Problem Statement + +Today's display ad pipeline on most publisher sites is structurally sequential +and browser-bound: + +1. Page HTML arrives at browser +2. Prebid.js (~300KB) downloads and parses +3. Smart Slots SDK scans the DOM to discover ad placements +4. `addAdUnits()` registers slot definitions +5.

GAM creative renders + +**Total time to ad visible: ~3,100ms.** + +The browser is the slowest possible place to run an auction. It must first download and parse +multiple SDKs, scan the DOM to discover what ad slots exist, and then fire SSP requests over +a consumer internet connection with high and variable latency. + +Trusted Server sits at the Fastly edge — milliseconds from the user, with data-center-to-data-center +RTT to Prebid Server (~20–30ms vs ~80–150ms from a browser). The server knows, from the request +URL alone, exactly which ad slots are available on any given page. There is no reason to wait for +the browser. + +--- + +## 2.

Non-Goals + +- Eliminating client-side GPT / Google Ad Manager — GAM remains in the rendering pipeline + for Phase 1. The GAM call (`securepubads.g.doubleclick.net`) moves server-side in a future phase. +- Dynamic slot discovery (reading the DOM) — this design commits to pre-defined, URL-matched + slot templates. Smart Slots' dynamic injection behavior is replaced by server knowledge. +- Changing the `AuctionOrchestrator` internally — the orchestrator already handles parallel + provider fan-out. This design adds a new trigger point, not new auction logic. + +--- + +## 4. Architecture + +### 4.1 New File: `creative-opportunities.toml` + +A new config file at the repo root, alongside `trusted-server.toml`. It holds all slot templates: +page pattern matching rules, ad formats, floor prices, and GAM targeting key-values. Bidder-level +params (placement IDs, account IDs) live in Prebid Server stored requests, keyed by slot ID — not +in this file. + +Loaded at build time via `include_str!()`, parsed into `Vec` at startup. +Ad ops can edit this file independently of server configuration. + +`floor_price` is the publisher-owned hard floor per slot — the source of truth for the minimum +acceptable bid price, enforced at the edge before bids reach the ad server. Any bid below the +floor is discarded at the orchestrator level before it enters `__ts_bids`. SSPs may apply their +own dynamic floors independently within their platforms; this floor is the publisher's baseline +that supersedes all other floor logic by virtue of being enforced earliest in the pipeline. + +**Schema:** + +```toml +[[slot]] +id = "atf_sidebar_ad" +page_patterns = ["/20*/"] +formats = [{ width = 300, height = 250 }] +floor_price = 0.50 + +[slot.targeting] +pos = "atf" +zone = "atfSidebar" + +[[slot]] +id = "below-content-ad" +page_patterns = ["/20*/"] +formats = [{ width = 300, height = 250 }, { width = 728, height = 90 }] +floor_price = 0.25 + +[slot.targeting] +pos = "btf" +zone = "belowContent" + +[[slot]] +id = "ad-homepage-0" +page_patterns = ["/", "/index.html"] +formats = [{ width = 970, height = 250 }, { width = 728, height = 90 }] +floor_price = 1.00 + +[slot.targeting] +pos = "atf" +zone = "homepage" +slot_index = "0" +``` + +**Rust type:** + +```rust +#[derive(Debug, Clone, serde::Deserialize)] +pub struct CreativeOpportunitySlot { + pub id: String, + pub page_patterns: Vec, + pub formats: Vec, + pub floor_price: Option, + pub targeting: HashMap, +} +``` + +### 4.2 URL Pattern Matching + +At request time, TS matches the request path against each slot's `page_patterns`. Patterns are +glob-style strings: + +- `/20*/` — matches all date-prefixed article paths (e.g., `/2024/01/my-article/`) +- `/` — matches the homepage exactly +- `/index.html` — exact match + +Multiple slots can match a single URL. All matching slots are collected and fed into a single +auction as separate impressions. Pattern matching is purely in-memory against the pre-parsed +config — sub-millisecond. + +### 4.3 Auction Trigger + +When slots are matched, TS immediately calls `AuctionOrchestrator::run_auction()` with the +matched slots converted to `AdSlot` objects. This happens at request receipt time — in parallel +with the origin fetch. + +The orchestrator's existing behaviour is unchanged: +- All providers (PBS, APS, any configured wrappers) are dispatched simultaneously +- Per-provider timeout budgets are enforced from the remaining auction deadline +- Floor price filtering, bid unification, and winning bid selection are applied as today +- PBS resolves bidder params from its stored requests by slot ID — no bidder params travel + through TS or the browser + +**On NextJS 14 (buffered mode):** TS must buffer the full origin response before forwarding. +This gives the auction the entire origin response time (~150–400ms typical) to run before +any HTML is forwarded. In practice, bids are often collected before origin even responds. + +**On NextJS 16 (streaming mode):** TS streams HTML chunks to the browser immediately. The +auction runs in parallel. Bid injection into `` must complete before the `` tag +is forwarded. If the auction has not returned by the time `` is encountered, TS waits +up to the remaining auction budget, then flushes with whatever bids have arrived (partial +results) or no targeting if timed out. Content after `` is never held. + +### 4.4 Head Injection + +TS injects two separate ``, not +> raw string interpolation. -Prebid.js is eliminated. The client-side ad bootstrap is replaced by a small inline script -(~20 lines) that reads `__ts_ad_slots` and `__ts_bids` and drives GPT directly: +> **Cache contract:** Any response with `__ts_bids` injected is per-user data and must +> not be cached. TS sets `Cache-Control: private, no-store` on the response before +> forwarding, overriding any conflicting cache headers from the publisher origin. +> `Surrogate-Control` and `Fastly-Surrogate-Control` are also stripped. + +### 4.5 Win Notifications + +Win notification responsibilities are split by where the truth lives: + +**`nurl` (SSP win event) — fired server-side.** When the orchestrator selects a winning +bid, TS fires a fire-and-forget background HTTP request to `nurl` from the edge +(edge→SSP RTT ~20–30ms, no auction-path latency cost). A per-integration switch +(`[integrations.prebid].fire_nurl_at_edge`, default `true`) handles cases where the PBS +deployment already fires win events internally to avoid double-firing. APS win +notification follows its own spec. + +**`burl` (billing event) — fired client-side.** `burl` is embedded per slot in +`__ts_bids` (see §4.4). The `__tsAdInit` script registers a GPT `slotRenderEnded` +listener after defining slots. On render: if `!event.isEmpty` and +`event.slot.getTargeting('hb_adid')[0] === bidData.hb_adid`, the client fires `burl` +via `navigator.sendBeacon`. This confirms both that the ad rendered and that our specific +Prebid bid (not a direct deal or backfill) won the GAM line item match. + +### 4.6 Client Residual + +Prebid.js is eliminated.

The +architecture is designed so that everything that can be cached, is. + +**What gets cached where:** + +| Asset | Cached at | Cacheability | +| ------------------------ | -------------------------------- | --------------------------------------------------------- | +| Origin HTML | Fastly edge HTTP cache | Yes, if origin sends `Cache-Control: public, max-age=...` | +| Origin CSS / fonts / JS | Fastly edge + browser | Yes (typically hashed URLs, immutable) | +| `tsjs` bundle | Fastly edge + browser | Yes (already content-hashed via `bundle.rs`, immutable) | +| `__ts_ad_slots` payload | Could be precomputed per pattern | In-memory match is sub-millisecond — not worth caching | +| `__ts_request_id` | **Never** | Per-request UUID, minted at request receipt | +| Bid results (`/ts-bids`) | In-process `bid_cache`, 30s TTL | Per-request, never shared across users | + +**Architecture:** + +1. Fastly's built-in HTTP cache stores the **origin response** keyed by URL. TS + does not implement its own HTML caching layer — it leverages the existing + Fastly cache. +2. On request: TS reads from cache (cache hit, ~5ms) or fetches from origin + (cache miss, ~150ms typical). +3. TS injects `__ts_ad_slots` + `__ts_request_id` at the `` open via the + existing `el.prepend()` head handler. This injection is per-request — origin + HTML in cache is unmodified. +4. TS forces `Transfer-Encoding: chunked` and streams the assembled response + to the browser. +5. The auction runs in parallel regardless of HTML cache state — bids land in + `bid_cache` keyed by `request_id`, served via `/ts-bids` when the client + fetches. + +The `bid_cache` (per-request bid results) and Fastly's HTML cache are +**independent systems**. HTML cache hit/miss does not affect auction firing; +auction firing does not affect HTML caching. + +**`Cache-Control` handling:** + +TS preserves the origin's `Cache-Control` header on the response sent to the +browser, with one override: when `__ts_request_id` is injected (any matched +page), TS sets `Cache-Control: private, no-store` on the **browser-facing** +response to prevent intermediate caches or the browser from caching the +per-user assembled HTML. The Fastly edge cache for the **origin** response is +unaffected — TS reads the cached origin HTML and assembles a fresh per-request +response on every hit. + +`Surrogate-Control` and `Fastly-Surrogate-Control` headers from origin are +preserved (they control Fastly's cache, not the browser's). + +**When caching doesn't apply:** + +- **Logged-in users** — origin typically returns `Cache-Control: private`. Falls + back to cache-miss timing (full origin fetch). +- **Personalized SSR** (per-user content, A/B test variants) — same. +- **Dynamic NextJS routes without ISR** — origin sends `Cache-Control: no-store` + or short max-age. Falls back to cache-miss timing. +- **First request after deploy or cache purge** — cold cache, full origin fetch. +- **Long-tail URLs** — low cache hit rate, treat as cache-miss case. + +For typical news / content publisher sites with anonymous visitors on stable +content pages, expect 70–90%+ edge cache hit rate. The cache-hit timing in §5 +is the realistic common case, not the optimistic best case. + --- ## 5. Request-Time Sequence +Sequence applies to all origins (WordPress, Drupal, Rails, NextJS 14/16, static sites). +TS forces chunked encoding on every response, so origin format is invisible from the +browser's perspective. + +### 5.1 Visual Sequence (full content + creative flow) + +```mermaid +sequenceDiagram + autonumber + participant B as Browser + participant E as TS Edge

When origin TTFB + body download exceeded the auction budget, the check fired after collecting the first SSP response, abandoning the second SSP's already-buffered response. This left responses with only one (possibly errored) SSP, causing remaining_ms == 0 which skipped the mediator, and select_winning_bids on the partial set returned zero bids. The deadline break is wrong in this context: SSP HTTP connections are already bounded by the backend first_byte_timeout set at dispatch time (1000ms per provider). By the time collect is called at origin EOF, all SSPs have either responded or been errored by Fastly's host. The select() calls drain instantly — no WASM-level deadline enforcement is needed or safe. Also add info-level log statements at dispatch, collect, and write_bids_to_state to make the auction pipeline observable without requiring a dashboard. --- .../src/auction/orchestrator.rs | 10 --------- crates/trusted-server-core/src/publisher.rs | 22 +++++++++++++++++++ 2 files changed, 22 insertions(+), 10 deletions(-) diff --git a/crates/trusted-server-core/src/auction/orchestrator.rs b/crates/trusted-server-core/src/auction/orchestrator.rs index 820031050..867bdf3a7 100644 --- a/crates/trusted-server-core/src/auction/orchestrator.rs +++ b/crates/trusted-server-core/src/auction/orchestrator.rs @@ -751,8 +751,6 @@ impl AuctionOrchestrator { request, } = dispatched; - let deadline = Duration::from_millis(u64::from(timeout_ms)); - log::info!( "Collecting {} in-flight SSP responses (timeout: {}ms remaining: {}ms)", pending_requests.len(), @@ -833,14 +831,6 @@ impl AuctionOrchestrator { } } - if auction_start.elapsed() >= deadline && !remaining.is_empty() { - log::warn!( - "Auction timeout ({}ms) reached, dropping {} remaining request(s)", - timeout_ms, - remaining.len() - ); - break; - } } let (mediator_response, winning_bids) = if let Some(mediator_name) = &self.config.mediator { diff --git a/crates/trusted-server-core/src/publisher.rs b/crates/trusted-server-core/src/publisher.rs index f5caa5710..5284e20f3 100644 --- a/crates/trusted-server-core/src/publisher.rs +++ b/crates/trusted-server-core/src/publisher.rs @@ -561,6 +561,15 @@ pub(crate) fn write_bids_to_state( price_granularity: PriceGranularity, ad_bids_state: &Arc>>, ) { + log::info!( + "write_bids_to_state: {} winning bid(s): [{}]", + winning_bids.len(), + winning_bids + .keys() + .cloned() + .collect::>() + .join(", ") + ); let bid_map = build_bid_map(winning_bids, price_granularity); let bids_script = build_bids_script(&bid_map); *ad_bids_state.write().expect("should write bid state") = Some(bids_script); @@ -655,11 +664,16 @@ async fn one_behind_loop( // Origin exhausted — pending holds the last chunk. // Collect the auction before feeding it to lol_html so that // the handler sees populated ad_bids_state. + log::info!("one_behind_loop: EOF — collecting dispatched auction"); let placeholder = Request::get("https://placeholder.invalid/"); let collect_ctx = make_collect_context(settings, services, &placeholder); let result = orchestrator .collect_dispatched_auction(dispatched, services, &collect_ctx) .await; + log::info!( + "one_behind_loop: collect complete — {} winning bid(s)", + result.winning_bids.len() + ); write_bids_to_state(&result.winning_bids, price_granularity, ad_bids_state); // Process the held last chunk (not is_last — finalization is separate). @@ -906,6 +920,14 @@ pub async fn handle_publisher_request( } else { None }; + log::info!( + "dispatch_auction: {}", + if dispatched_auction.is_some() { + "Some — auction running async" + } else { + "None — falling back to sync or skipped" + } + ); // Only advertise encodings the rewrite pipeline can decode and re-encode. restrict_accept_encoding(&mut req); From f172f4477c60ae0fc0e0d68b0d9f969652dc092f Mon Sep 17 00:00:00 2001 From: prk-Jr Date: Mon, 11 May 2026 13:15:23 +0530 Subject: [PATCH 047/315] Cargo fmt --- crates/trusted-server-core/src/auction/orchestrator.rs | 1 - crates/trusted-server-core/src/publisher.rs | 6 +----- 2 files changed, 1 insertion(+), 6 deletions(-) diff --git a/crates/trusted-server-core/src/auction/orchestrator.rs b/crates/trusted-server-core/src/auction/orchestrator.rs index 867bdf3a7..e9d8fa198 100644 --- a/crates/trusted-server-core/src/auction/orchestrator.rs +++ b/crates/trusted-server-core/src/auction/orchestrator.rs @@ -830,7 +830,6 @@ impl AuctionOrchestrator { log::warn!("A provider request failed during collection: {:?}", e); } } - } let (mediator_response, winning_bids) = if let Some(mediator_name) = &self.config.mediator { diff --git a/crates/trusted-server-core/src/publisher.rs b/crates/trusted-server-core/src/publisher.rs index 5284e20f3..3a9eb0895 100644 --- a/crates/trusted-server-core/src/publisher.rs +++ b/crates/trusted-server-core/src/publisher.rs @@ -564,11 +564,7 @@ pub(crate) fn write_bids_to_state( log::info!( "write_bids_to_state: {} winning bid(s): [{}]", winning_bids.len(), - winning_bids - .keys() - .cloned() - .collect::>() - .join(", ") + winning_bids.keys().cloned().collect::>().join(", ") ); let bid_map = build_bid_map(winning_bids, price_granularity); let bids_script = build_bids_script(&bid_map); From 14cd493ee907fbf2cce5030062bfed4ccac41043 Mon Sep 17 00:00:00 2001 From: prk-Jr Date: Mon, 11 May 2026 13:32:28 +0530 Subject: [PATCH 048/315] Fix mediator always skipped when origin body exceeds SSP auction budget MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit In collect_dispatched_auction, the mediator was skipped when remaining_budget_ms(auction_start, timeout_ms) == 0. In the async-dispatch path, auction_start is set before pending_origin.wait(), so elapsed time includes the full origin TTFB and body download. For heavy SSR pages (autoblog), this exceeds the 1500ms SSP budget, making remaining_ms == 0 at every collection and causing the mediator to be permanently skipped. The mediator (adserver_mock) is the primary bid source — SSPs alone return no bids. Skipping it means window.__ts_bids == {} on every full page load, while handle_page_bids (which uses the sequential run_auction path) works correctly because it measures remaining time from after SSP collection. Fix: give the mediator its own configured timeout (mediator.timeout_ms()) instead of the exhausted SSP budget. This mirrors how run_parallel_mediation works: the mediator's deadline is independent of SSP round-trip time. Side effect: mediator backend name is now stable (always t1000 for adserver_mock) rather than varying per request with remaining_ms. --- .../src/auction/orchestrator.rs | 32 +++++++++---------- 1 file changed, 16 insertions(+), 16 deletions(-) diff --git a/crates/trusted-server-core/src/auction/orchestrator.rs b/crates/trusted-server-core/src/auction/orchestrator.rs index e9d8fa198..892ff9ebb 100644 --- a/crates/trusted-server-core/src/auction/orchestrator.rs +++ b/crates/trusted-server-core/src/auction/orchestrator.rs @@ -835,24 +835,25 @@ impl AuctionOrchestrator { let (mediator_response, winning_bids) = if let Some(mediator_name) = &self.config.mediator { match self.providers.get(mediator_name.as_str()) { Some(mediator) => { - let remaining_ms = remaining_budget_ms(auction_start, timeout_ms); - if remaining_ms == 0 { - log::warn!("Auction timeout exhausted during bidding — skipping mediator"); - let winning = self.select_winning_bids(&responses, &floor_prices); - return OrchestrationResult { - provider_responses: responses, - mediator_response: None, - winning_bids: winning, - total_time_ms: auction_start.elapsed().as_millis() as u64, - metadata: HashMap::new(), - }; - } + // Use the mediator's own configured timeout, not the remaining SSP + // budget.

Unlike the `Stream` path, which drives `one_behind_loop` to collect the dispatched auction at origin EOF, the `BufferedProcessed` branch previously discarded `dispatched_auction` entirely — so `ad_bids_state` stayed `None` and lol_html injected the fallback `window.__ts_bids = {}` instead of real bids. Fix: collect the in-flight dispatched auction in the `BufferedProcessed` branch before calling `process_response_streaming`, using the same `collect_dispatched_auction` + `write_bids_to_state` pattern that the stream path uses.

unify the ourBidWon check (hb_adid confirmation with hb_bidder fallback for APS bids) across both implementations - Wire validate_slot_id into Settings::prepare_runtime so every load path (including env-injected slots on runtime-config adapters) rejects invalid slot IDs; build.rs settings stub gains a no-op - Normalize the client-controlled page-bids path parameter: strip query/fragment and force a leading slash before glob matching - Document the deliberate Cache-Control private, max-age=0 choice (BFCache eligibility per design spec section 4.7, not no-store) - Align orchestrator collect path with the parallel path: use parse_response_with_context for providers and the mediator, and add a defense-in-depth deadline check to the collect select-loop - Migrate adserver_mock off request-scoped Mutex state: the SSP bid index is rebuilt in parse_response_with_context from the context's provider responses; document why APS's slot_id_map cannot follow yet - Make platform_response_to_fastly infallible; drop the dead error arms - Remove redundant PriceGranularity::dense and MediaType::banner constructors in favor of Default-based serde field defaults - Clarify that the Prebid stored-request fallback cannot fire for the client /auction path (every ad unit carries a trustedServer entry) - Consolidate GPT JS suites under test/integrations/gpt/, replace the leaked module-scope addEventListener patch with a restored wrapper, and add installSpaAuctionHook coverage (pushState/replaceState/ popstate, stale-response guard, non-OK response, idempotence) --- crates/js/lib/src/core/types.ts | 6 + crates/js/lib/src/integrations/gpt/index.ts | 24 ++- .../integrations/gpt/ad_init.test.ts} | 95 ++++++---- .../test/integrations/gpt/spa_hook.test.ts | 167 ++++++++++++++++++ crates/trusted-server-core/build.rs | 8 + .../src/auction/orchestrator.rs | 157 ++++++++-------- .../trusted-server-core/src/auction/types.rs | 19 +- .../src/creative_opportunities.rs | 8 +- .../src/integrations/adserver_mock.rs | 147 ++++++++------- .../src/integrations/aps.rs | 5 + .../src/integrations/gpt_bootstrap.js | 15 +- .../src/integrations/prebid.rs | 7 + .../trusted-server-core/src/price_bucket.rs | 7 - crates/trusted-server-core/src/publisher.rs | 50 +++++- crates/trusted-server-core/src/settings.rs | 45 ++++- 15 files changed, 545 insertions(+), 215 deletions(-) rename crates/js/lib/{src/integrations/gpt/index.test.ts => test/integrations/gpt/ad_init.test.ts} (89%) create mode 100644 crates/js/lib/test/integrations/gpt/spa_hook.test.ts diff --git a/crates/js/lib/src/core/types.ts b/crates/js/lib/src/core/types.ts index 4fb99f3b4..1bdf1057b 100644 --- a/crates/js/lib/src/core/types.ts +++ b/crates/js/lib/src/core/types.ts @@ -98,6 +98,12 @@ export interface TsjsApi { servicesEnabled?: boolean;

Previously an iframe under slot A could request slot B's adId and receive slot B's creative while firing slot B's beacons. - Refresh ad units now include configured client-side bidders by merging matching pbjs.adUnits bid entries, so native Prebid demand is not dropped on refresh/scroll impressions. - Inline GPT bootstrap wraps its internal refresh with the adInitRefreshInProgress sentinel, mirroring the TS adInit so a pre-installed slim-Prebid refresh wrapper does not clear TS targeting.

GPT requires a display() call to register/render a slot, so TS-owned first-impression slots no-op ("defineSlot was called without a matching display call") and miss impressions. Reused publisher-owned slots are unaffected because the publisher already displayed them. Track TS-defined slot element IDs separately, display() them once after services are enabled, and keep refresh() for reused publisher-owned slots only. Mirror the change in the inline gpt_bootstrap.js. Add Vitest coverage for the TS-owned display path and keep the refresh-bypass test on a reused slot. --- crates/js/lib/src/integrations/gpt/index.ts | 32 ++++++++--- .../lib/test/integrations/gpt/ad_init.test.ts | 53 ++++++++++++++++++- .../src/integrations/gpt_bootstrap.js | 23 ++++++-- 3 files changed, 97 insertions(+), 11 deletions(-) diff --git a/crates/js/lib/src/integrations/gpt/index.ts b/crates/js/lib/src/integrations/gpt/index.ts index 9fd9ca5c3..2effbc593 100644 --- a/crates/js/lib/src/integrations/gpt/index.ts +++ b/crates/js/lib/src/integrations/gpt/index.ts @@ -392,8 +392,14 @@ export function installTsAdInit(): void { // Slots TS defined itself — tracked for SPA destroy.

EC generation is the adapter's real-browser-gated responsibility; the duplicate inline call re-ran for any navigation with no real-browser signal, so a non-real-browser client could get an IP-derived EC minted in memory and forwarded to PBS/APS even though the adapter blocked EC operations. Gate /__ts/page-bids slot output on the effective ad-stack condition (auction kill switch + consent), not just winning bids. Returning slots while the stack is disabled let the SPA hook run adInit() and create or refresh GPT slots client-side, defeating the kill switch. This matches the publisher navigation path's should_run_server_side_ad_stack gate. Add deny_unknown_fields to the top-level creative-opportunities config and nested provider/format structs so misspelled keys fail at startup instead of silently disabling or mis-timing the ad stack. Add regression tests for all three and update the page-bids tests to isolate the bot/prefetch variable from the consent gate. --- .../src/creative_opportunities.rs | 46 ++++ crates/trusted-server-core/src/publisher.rs | 245 ++++++++++++++---- 2 files changed, 239 insertions(+), 52 deletions(-) diff --git a/crates/trusted-server-core/src/creative_opportunities.rs b/crates/trusted-server-core/src/creative_opportunities.rs index cf2b401d6..2b3fa6e72 100644 --- a/crates/trusted-server-core/src/creative_opportunities.rs +++ b/crates/trusted-server-core/src/creative_opportunities.rs @@ -16,6 +16,7 @@ use crate::settings::vec_from_seq_or_map; /// Top-level configuration for the creative opportunities system. #[derive(Debug, Clone, Deserialize, Serialize)] +#[serde(deny_unknown_fields)] pub struct CreativeOpportunitiesConfig { /// GAM network ID used to build default unit paths. pub gam_network_id: String, @@ -288,6 +289,7 @@ impl CreativeOpportunitySlot { /// An ad format combining a media type with pixel dimensions. #[derive(Debug, Clone, Deserialize, Serialize)] +#[serde(deny_unknown_fields)] pub struct CreativeOpportunityFormat { /// Creative width in pixels. pub width: u32, @@ -320,6 +322,7 @@ impl CreativeOpportunityFormat { /// Provider-specific slot identifiers for a [`CreativeOpportunitySlot`]. #[derive(Debug, Clone, Default, Deserialize, Serialize)] +#[serde(deny_unknown_fields)] pub struct SlotProviders { /// Amazon Publisher Services (APS/TAM) slot parameters. pub aps: Option, @@ -333,6 +336,7 @@ pub struct SlotProviders { /// APS-specific parameters for a slot. #[derive(Debug, Clone, Deserialize, Serialize)] +#[serde(deny_unknown_fields)] pub struct ApsSlotParams { /// The APS slot ID string used when making TAM bid requests. pub slot_id: String, @@ -345,6 +349,7 @@ pub struct ApsSlotParams { /// When `bidders` is non-empty the map is forwarded verbatim, bypassing /// automatic expansion (useful for slots that need explicit per-bidder params). #[derive(Debug, Clone, Deserialize, Serialize)] +#[serde(deny_unknown_fields)] pub struct PrebidSlotParams { /// Per-bidder inline params map.

Strip surrogate cache headers on every Set-Cookie response — even one keeping a stricter no-store directive — and treat no-store as protected in the operator-header guard. Reject OPTIONS /__ts/page-bids at the adapter so the side-effecting endpoint never grants a CORS preflight the publisher origin might. Drain every dispatched SSP request in the collect loop instead of breaking on the auction deadline, so a slow origin can no longer discard SSP responses that already arrived. Reject empty/whitespace div_id overrides at runtime validation, which would otherwise bind a slot to the first id-bearing DOM element. Recover Prebid refresh params and client-side bids from candidate codes ([gpt element id, injected div_id]) so container-backed slots keep the publisher's configured demand on refresh/scroll auctions. --- .../js/lib/src/integrations/prebid/index.ts | 52 +++-- .../test/integrations/prebid/index.test.ts | 68 +++++++ .../trusted-server-adapter-fastly/src/main.rs | 100 +++++++--- .../src/route_tests.rs | 185 +++++++++++++++++- .../src/auction/orchestrator.rs | 18 +- .../src/creative_opportunities.rs | 41 ++++ 6 files changed, 409 insertions(+), 55 deletions(-) diff --git a/crates/js/lib/src/integrations/prebid/index.ts b/crates/js/lib/src/integrations/prebid/index.ts index 835d28fdb..fe175b44d 100644 --- a/crates/js/lib/src/integrations/prebid/index.ts +++ b/crates/js/lib/src/integrations/prebid/index.ts @@ -342,6 +342,27 @@ function firstTargetingValue(values: string[] | undefined): string | undefined { return values?.find((value) => value.length > 0); } +/** + * Find the publisher's original `pbjs.adUnits` entry for a refreshing slot. + * + * A TS-owned GPT slot may be defined on `${div_id}-container`, so the GPT + * element id used as the synthetic refresh ad unit code can differ from the + * inner `div_id` the publisher keyed their Prebid ad unit by.

Previously client-provided EIDs from the request body or ts-eids cookie were resolved unconditionally, so a US/GPC or US-Privacy opt-out context — where EC identity use is denied but a non-personalized auction may still run — could forward persistent EIDs, since `gate_eids_by_consent` only strips on TCF/GDPR signals. This matches the publisher and /__ts/page-bids paths. Refresh TS-defined GPT slots when the publisher disabled initial load. With pubads().disableInitialLoad(), display() only registers a freshly defined slot and the ad request must come from refresh(); TS-owned first-impression slots were only display()ed, so they rendered blank. A wrapper around disableInitialLoad() records the state on window.tsjs, and adInit() refreshes its own slots when it is set (bundle and gpt_bootstrap.js).

An invalid pattern such as `["["]` now fails the build instead of being embedded and dropped at runtime settings load. - Reject an empty/whitespace div_id override at build time, mirroring CreativeOpportunitySlot::validate_runtime. - Validate nested creative-slot fields (formats, providers, aps, prebid) against the runtime structs' deny_unknown_fields so env-injected typos like `mediatype` or `slotId` fail the build, not runtime. Observability and correctness: - Mirror the parallel auction path on the dispatch/collect path: attribute provider parse failures (error_type + message) and transport failures (via failed_backend_name) in provider_details. - Warn on each page pattern dropped during compile_patterns so a mixed valid/invalid set is visible to operators. - Escape the terminator in the configured slim_prebid_url so it cannot break out of its inline script tag. - Guard SPA navigation: onNavigate no-ops when the path is unchanged, so popstate (hash-only or same-path back/forward) no longer re-requests impressions. Docs and comments: - Update the GPT scroll/refresh handoff comment to reflect installSpaAuctionHook + /__ts/page-bids ownership of SPA navigation. - Note that targeting.zone is not forwarded when explicit prebid.bidders are set. - Split the page-bids same-origin-gate and path-normalization docs onto their own functions; remove the stale # Panics section on handle_publisher_request. - Correct the stale slotRenderEnded/beacon comment in gpt_bootstrap.js. Tests added for div_id, nested-field, slim_prebid_url escaping, and SPA same-path guard behavior. --- crates/js/lib/src/integrations/gpt/index.ts | 13 +- .../test/integrations/gpt/spa_hook.test.ts | 50 ++++- crates/trusted-server-core/build.rs | 18 +- .../src/auction/orchestrator.rs | 48 ++++- .../src/creative_opportunities.rs | 24 ++- .../src/creative_slot_build_check.rs | 186 +++++++++++++++++- .../src/integrations/gpt.rs | 56 +++++- .../src/integrations/gpt_bootstrap.js | 7 +- crates/trusted-server-core/src/publisher.rs | 16 +- 9 files changed, 369 insertions(+), 49 deletions(-) diff --git a/crates/js/lib/src/integrations/gpt/index.ts b/crates/js/lib/src/integrations/gpt/index.ts index aad98c96c..30071220d 100644 --- a/crates/js/lib/src/integrations/gpt/index.ts +++ b/crates/js/lib/src/integrations/gpt/index.ts @@ -661,8 +661,15 @@ export function installSpaAuctionHook(): void { ts.spaHookInstalled = true; let inflight: AbortController | null = null; + // Last path an auction was run for. popstate fires for hash-only and + // same-pathname back/forward (scroll restoration), and pushState/replaceState + // can be called with the current URL, so guard every entry point against + // re-requesting impressions for a path we already loaded. + let currentPath = location.pathname; async function onNavigate(path: string): Promise { + if (path === currentPath) return; + currentPath = path; inflight?.abort(); const controller = new AbortController(); inflight = controller; @@ -696,12 +703,10 @@ export function installSpaAuctionHook(): void { function patchHistoryMethod(method: 'pushState' | 'replaceState'): void { const original = history[method].bind(history); history[method] = function (state: unknown, unused: string, url?: string | URL | null): void { - const prevPath = location.pathname; original(state, unused, url); const newPath = url ? new URL(String(url), location.href).pathname : location.pathname; - if (newPath !== prevPath) { - void onNavigate(newPath); - } + // onNavigate no-ops when newPath equals the last loaded path. + void onNavigate(newPath); }; } diff --git a/crates/js/lib/test/integrations/gpt/spa_hook.test.ts b/crates/js/lib/test/integrations/gpt/spa_hook.test.ts index 751b081f0..6be0a8484 100644 --- a/crates/js/lib/test/integrations/gpt/spa_hook.test.ts +++ b/crates/js/lib/test/integrations/gpt/spa_hook.test.ts @@ -21,6 +21,12 @@ async function flushAsync(): Promise { describe('installSpaAuctionHook', () => { let fetchStub: ReturnType; + // popstate listeners registered by each module import.

The EdgeZero entry point re-applies an HttpResponse enforce_set_cookie_cache_privacy after ec_finalize_response and request-filter effects so a late EC Set-Cookie cannot reach a shared cache. Adds middleware tests for both cases. P1 — empty page-bids must not enable GPT services: adInit() only enables GPT services when it has a slot to display or refresh, and the SPA hook skips adInit() for an empty page-bids response unless prior TS state needs sweeping. Prevents a consent-denied or kill-switched navigation from activating the publisher's GPT setup. P2 — scope Prebid refresh targeting to the refreshed slots: setTargetingForGPTAsync is called with the synthetic refresh ad-unit codes so a one-slot refresh no longer mutates unrelated GPT slots. P2 — validate nested slot value shapes at build time: The creative-slot build check now validates media_type against the runtime MediaType variants, targeting as a string map, page_patterns as strings, providers.aps.slot_id as a string, providers.prebid.bidders as a map, and floor_price as a number — closing build-green/runtime-broken gaps. A drift-guard test ties media_type to the runtime enum. CI — suppress CodeQL cleartext-logging false positives: Annotate the provider/mediator "not registered" warnings; they log static config identifiers, not secrets. --- .../trusted-server-adapter-fastly/src/main.rs | 98 +------ .../src/middleware.rs | 218 +++++++++++++++- .../src/auction/orchestrator.rs | 4 + .../src/creative_slot_build_check.rs | 246 ++++++++++++++++++ .../lib/src/integrations/gpt/index.ts | 26 +- .../lib/src/integrations/prebid/index.ts | 7 +- .../lib/test/integrations/gpt/ad_init.test.ts | 34 +++ .../test/integrations/gpt/spa_hook.test.ts | 43 +++ .../test/integrations/prebid/index.test.ts | 51 ++++ 9 files changed, 636 insertions(+), 91 deletions(-) diff --git a/crates/trusted-server-adapter-fastly/src/main.rs b/crates/trusted-server-adapter-fastly/src/main.rs index 274b37c22..711aa2008 100644 --- a/crates/trusted-server-adapter-fastly/src/main.rs +++ b/crates/trusted-server-adapter-fastly/src/main.rs @@ -6,8 +6,7 @@ use edgezero_core::app::Hooks as _; use edgezero_core::body::Body as EdgeBody; use edgezero_core::config_store::ConfigStoreHandle; use edgezero_core::http::{ - header, HeaderName, HeaderValue, Method, Request as HttpRequest, Response as HttpResponse, - StatusCode, + header, HeaderValue, Method, Request as HttpRequest, Response as HttpResponse, StatusCode, }; use error_stack::Report; use fastly::http::Method as FastlyMethod; @@ -16,10 +15,7 @@ use fastly::{Request as FastlyRequest, Response as FastlyResponse}; use trusted_server_core::auction::endpoints::handle_auction; use trusted_server_core::auction::AuctionOrchestrator; use trusted_server_core::auth::enforce_basic_auth; -use trusted_server_core::constants::{ - COOKIE_SHAREDID, COOKIE_TS_EIDS, ENV_FASTLY_IS_STAGING, ENV_FASTLY_SERVICE_VERSION, - HEADER_X_GEO_INFO_AVAILABLE, HEADER_X_TS_ENV, HEADER_X_TS_VERSION, -}; +use trusted_server_core::constants::{COOKIE_SHAREDID, COOKIE_TS_EIDS}; use trusted_server_core::ec::batch_sync::handle_batch_sync; use trusted_server_core::ec::consent::ec_consent_withdrawn; use trusted_server_core::ec::device::DeviceSignals; @@ -374,6 +370,11 @@ fn edgezero_main(mut req: FastlyRequest, config_store: ConfigStoreHandle) { if let Some(effects) = &request_filter_effects { effects.apply_to_response(&mut response); } + // Final cache guard: EC finalization and request-filter + // effects above may have added a per-user Set-Cookie after + // `apply_finalize_headers` ran, so re-apply the privacy + // downgrade before send, mirroring legacy_main. + crate::middleware::enforce_set_cookie_cache_privacy(&mut response); compat::to_fastly_response(response).send_to_client(); if ec_state.is_real_browser { @@ -403,6 +404,9 @@ fn edgezero_main(mut req: FastlyRequest, config_store: ConfigStoreHandle) { if let Some(effects) = &request_filter_effects { effects.apply_to_response(&mut response); } + // Final cache guard for the no-EC-finalization fallback: request-filter + // effects may still have added a per-user Set-Cookie after finalize headers. + crate::middleware::enforce_set_cookie_cache_privacy(&mut response); compat::to_fastly_response(response).send_to_client(); } @@ -1212,84 +1216,10 @@ fn publisher_response_carries_body(method: &Method, status: StatusCode) -> bool /// version/staging, then operator-configured `settings.response_headers`. /// This means operators can intentionally override any managed header. fn finalize_response(settings: &Settings, geo_info: Option<&GeoInfo>, response: &mut HttpResponse) { - if let Some(geo) = geo_info { - geo.set_response_headers(response); - } else { - response.headers_mut().insert( - HEADER_X_GEO_INFO_AVAILABLE, - HeaderValue::from_static("false"), - ); - } - - if let Ok(v) = ::std::env::var(ENV_FASTLY_SERVICE_VERSION) { - if let Ok(value) = HeaderValue::from_str(&v) { - response.headers_mut().insert(HEADER_X_TS_VERSION, value); - } else { - log::warn!("Skipping invalid FASTLY_SERVICE_VERSION response header value"); - } - } - if ::std::env::var(ENV_FASTLY_IS_STAGING).as_deref() == Ok("1") { - response - .headers_mut() - .insert(HEADER_X_TS_ENV, HeaderValue::from_static("staging")); - } - - // Any response that sets a per-user cookie (notably the EC identity cookie - // minted on a visitor's first navigation) must never be shared-cached, or a - // shared cache could replay one user's Set-Cookie to others.

it was only used by #[tokio::test] and was linking the runtime into the wasm prod build. Confirmed the release wasm adapter build no longer pulls tokio. - Roll back the SPA currentPath on a failed /__ts/page-bids fetch so a transient error no longer permanently strands that route (gpt/index.ts). Build/runtime parity and diagnostics: - Bound creative-opportunity format width/height to u32 range at build time so values the runtime u32 cannot hold are rejected early. - Add #[serde(deny_unknown_fields)] to the build.rs config stub to match the runtime type and reject mistyped table keys at build time. - Warn when the end-tag handler is absent so a silently non-rendering server-side ad feature is diagnosable. - Log dropped slot bidders that are neither configured nor the aps provider. - Log build_bid_index collisions (multiple bids per seat/imp). JS correctness: - Narrow uid.atype to a number before the range check in sanitizeAuctionUid. - Resolve findInjectedSlotForRefresh by exact/container match before the prefix fallback, with a regression test for prefix-overlapping div_ids. - Guard the gpt_bootstrap prefix scan against an empty div_id. - Route injectAdmIntoSlot through findSlotElementByDivId for consistency. Cleanup and docs: - Remove the dead has_post_processors routing dependency from classify_response_route and (now unused) handle_publisher_request. - Extract the duplicated EID resolution/consent-gating/device tail shared by the initial-page and page-bids dispatch paths into one helper. - Anchor the surrogate cache-header list in a shared const so the legacy and EdgeZero Set-Cookie privacy paths stay aligned. - Refresh stale docs (PublisherResponse::Stream, the publisher module platform-coupling note, and UserInfo.eids consent-gate location). --- crates/trusted-server-adapter-axum/src/app.rs | 1 - .../src/app.rs | 1 - .../trusted-server-adapter-fastly/src/app.rs | 1 - .../trusted-server-adapter-fastly/src/main.rs | 6 +- .../src/middleware.rs | 11 +- crates/trusted-server-adapter-spin/src/app.rs | 1 - crates/trusted-server-core/Cargo.toml | 2 +- crates/trusted-server-core/build.rs | 1 + .../trusted-server-core/src/auction/types.rs | 6 +- .../src/creative_slot_build_check.rs | 10 +- .../trusted-server-core/src/html_processor.rs | 9 + .../src/integrations/adserver_mock.rs | 24 +- .../src/integrations/gpt_bootstrap.js | 1 + .../src/integrations/prebid.rs | 11 + crates/trusted-server-core/src/publisher.rs | 262 +++++++++--------- .../lib/src/integrations/gpt/index.ts | 16 +- .../lib/src/integrations/prebid/index.ts | 24 +- .../test/integrations/prebid/index.test.ts | 57 ++++ 18 files changed, 276 insertions(+), 168 deletions(-) diff --git a/crates/trusted-server-adapter-axum/src/app.rs b/crates/trusted-server-adapter-axum/src/app.rs index 882aa69c8..8cd53d48f 100644 --- a/crates/trusted-server-adapter-axum/src/app.rs +++ b/crates/trusted-server-adapter-axum/src/app.rs @@ -176,7 +176,6 @@ async fn dispatch_fallback( }; handle_publisher_request( &state.settings, - &state.registry, services, None, &mut ec_context, diff --git a/crates/trusted-server-adapter-cloudflare/src/app.rs b/crates/trusted-server-adapter-cloudflare/src/app.rs index 92b1c17e7..d4e8fb3d6 100644 --- a/crates/trusted-server-adapter-cloudflare/src/app.rs +++ b/crates/trusted-server-adapter-cloudflare/src/app.rs @@ -305,7 +305,6 @@ fn build_router(state: &Arc) -> RouterService { }; handle_publisher_request( &state.settings, - &state.registry, &services, None, &mut ec_context, diff --git a/crates/trusted-server-adapter-fastly/src/app.rs b/crates/trusted-server-adapter-fastly/src/app.rs index 8d2d9ae13..13a348314 100644 --- a/crates/trusted-server-adapter-fastly/src/app.rs +++ b/crates/trusted-server-adapter-fastly/src/app.rs @@ -729,7 +729,6 @@ async fn dispatch_fallback( }; handle_publisher_request( &state.settings, - &state.registry, &publisher_services, ec.kv_graph.as_ref(), &mut ec.ec_context, diff --git a/crates/trusted-server-adapter-fastly/src/main.rs b/crates/trusted-server-adapter-fastly/src/main.rs index e1c0da9a5..30e91b01f 100644 --- a/crates/trusted-server-adapter-fastly/src/main.rs +++ b/crates/trusted-server-adapter-fastly/src/main.rs @@ -1270,7 +1270,6 @@ async fn route_request( match handle_publisher_request( settings, - integration_registry, runtime_services, kv_graph.as_ref(), &mut ec_context, @@ -1399,8 +1398,9 @@ fn enforce_set_cookie_cache_privacy(response: &mut FastlyResponse) { // keeping a stricter `no-store`/`private` directive — Surrogate-Control is // independent of Cache-Control and would otherwise let a shared cache store // and replay one visitor's Set-Cookie. - response.remove_header("surrogate-control"); - response.remove_header("fastly-surrogate-control"); + for name in crate::middleware::SURROGATE_CACHE_HEADERS { + response.remove_header(*name); + } let already_uncacheable = response .get_header_str("cache-control") .map(str::to_ascii_lowercase) diff --git a/crates/trusted-server-adapter-fastly/src/middleware.rs b/crates/trusted-server-adapter-fastly/src/middleware.rs index 6aa9cddd4..91b7dcdec 100644 --- a/crates/trusted-server-adapter-fastly/src/middleware.rs +++ b/crates/trusted-server-adapter-fastly/src/middleware.rs @@ -257,6 +257,12 @@ pub(crate) fn apply_finalize_headers( } } +/// Surrogate cache headers stripped from every cookie-bearing response.

The blocking findings were all cross-adapter parity gaps in the server-side auction: - Build the geo-aware EC context in the /auction handlers on Axum, Cloudflare, and Spin. They passed EcContext::default(), leaving jurisdiction Unknown and failing the consent gate closed even for consented users. A shared per-adapter build_ec_context helper now serves /auction, page-bids, and the publisher fallback, and logs (rather than swallows) a malformed-consent read error. - Wire GET /__ts/page-bids and its OPTIONS->403 CSRF guard on the Fastly EdgeZero path and all three portability adapters, reusing core handle_page_bids and a shared page_bids_preflight_denied() helper. Previously it was Fastly-legacy-only, so SPA re-auction silently fell through to the origin on every other path. - Add trusted_server_core::response_privacy with the Set-Cookie cache-privacy downgrade and the uncacheable-operator-header guard, and call it from every adapter's apply_finalize_headers so a shared cache (Cloudflare) can no longer serve an operator/origin public Cache-Control on a cookie-bearing response. Also address the inline and non-blocking findings: warn on a dropped dispatched auction for bodiless responses, extract build_slot_json shared by the initial-page and page-bids paths, use creative_opportunity_slots() everywhere, drop the PBS id->ad_id fallback, log APS slot-id collisions, align the parallel provider parse with the collect path, remove the dead sync buffer_publisher_response, factor the mediator placeholder request, drop the unused toml dependency, guard MediaType against a future serde(default), and document the Fastly-only KV EID enrichment. JS: dedup win/billing beacons across concurrent renders, add the SSR guard to installSlimPrebidLoader, and short-circuit waitForSlotElements on an already-aborted signal. Add regression tests for the currentPath rollback and the u32::MAX format-dimension rejection. --- Cargo.lock | 1 - crates/trusted-server-adapter-axum/src/app.rs | 94 +++++--- .../src/middleware.rs | 23 +- .../src/app.rs | 81 ++++--- .../src/middleware.rs | 24 +-- .../trusted-server-adapter-fastly/Cargo.toml | 1 - .../trusted-server-adapter-fastly/src/app.rs | 52 ++++- .../src/middleware.rs | 93 ++------ crates/trusted-server-adapter-spin/src/app.rs | 97 ++++++--- .../src/middleware.rs | 23 +- .../src/auction/orchestrator.rs | 9 +- .../trusted-server-core/src/auction/types.rs | 5 + .../src/creative_slot_build_check.rs | 14 ++ .../src/integrations/aps.rs | 15 +- .../src/integrations/prebid.rs | 5 +- crates/trusted-server-core/src/lib.rs | 1 + crates/trusted-server-core/src/publisher.rs | 202 +++++++++--------- .../src/response_privacy.rs | 180 ++++++++++++++++ .../lib/src/integrations/gpt/index.ts | 19 ++ .../test/integrations/gpt/spa_hook.test.ts | 33 +++ trusted-server.toml | 5 +- 21 files changed, 654 insertions(+), 323 deletions(-) create mode 100644 crates/trusted-server-core/src/response_privacy.rs diff --git a/Cargo.lock b/Cargo.lock index e026ef3af..629e5df60 100644 --- a/Cargo.lock +++ b/Cargo.lock @@ -3713,7 +3713,6 @@ dependencies = [ "log-fastly", "serde", "serde_json", - "toml", "trusted-server-core", "url", "urlencoding", diff --git a/crates/trusted-server-adapter-axum/src/app.rs b/crates/trusted-server-adapter-axum/src/app.rs index 953a0839f..18548c631 100644 --- a/crates/trusted-server-adapter-axum/src/app.rs +++ b/crates/trusted-server-adapter-axum/src/app.rs @@ -19,7 +19,8 @@ use trusted_server_core::proxy::{ handle_first_party_proxy_sign, }; use trusted_server_core::publisher::{ - AuctionDispatch, buffer_publisher_response_async, handle_publisher_request, handle_tsjs_dynamic, + AuctionDispatch, buffer_publisher_response_async, handle_page_bids, handle_publisher_request, + handle_tsjs_dynamic, page_bids_preflight_denied, }; use trusted_server_core::request_signing::{ handle_trusted_server_discovery, handle_verify_signature, @@ -129,6 +130,34 @@ where .unwrap_or_else(|e| http_error(&e))) } +// --------------------------------------------------------------------------- +// EC context +// --------------------------------------------------------------------------- + +/// Builds the geo-aware [`EcContext`] for consent-gated endpoints (`/auction`, +/// `/__ts/page-bids`, and the publisher fallback). +/// +/// Mirrors the Fastly entry point: `EcContext::default()` leaves jurisdiction +/// Unknown, which fails the auction consent gate closed even for consented +/// users.

Slots merge across runs: --page-pattern unions patterns into a re-seen slot, existing slots are preserved, and --replace wipes. Ephemeral div-id noise (React hashes, -container, hex UUIDs) is normalized to stable prefixes so verify matches across renders, and TOML keys/strings are escaped defensively. Add --cookie to ad-templates generate and verify so a valid bot-protection clearance cookie can carry the browser audit past an origin challenge.

EC +finalization can perform a second pre-send read-modify-write lookup while +ingesting `ts-eids` or `sharedId`. Post-send pull sync performs another lookup +for eligibility and then one read-modify-write lookup per successful partner. + +When a request contains a valid-looking EC cookie but its KV row is missing, +generation is skipped because an EC ID is already active. Browser EID ingestion +and pull sync both reject the missing root, leaving the request in a permanent +degraded state until the cookie expires. + +The cookie and live KV entry currently both have a one-year lifetime and neither +is refreshed on ordinary returning visits. The concrete correctness defect is +therefore missing-row recovery, not a general long-term mismatch between two +rolling expiration policies. + +## Scope + +This change covers the publisher-navigation EC path on Fastly, shared core EC +snapshot and mutation primitives, response finalization, and pull sync. It does +not change batch-sync root-creation policy, introduce sampled sliding TTL +refresh, change the EC cookie wire format, or refactor unrelated adapters. + +GitHub issue #880 separately owns avoiding pull-sync reads when no partners are +enabled or when a browser-side completeness marker proves the current partner +set is complete. This design does not add that early no-partner optimization, +the completeness marker, partner-set fingerprinting, or marker validation. Its +pull-sync changes consume the single request-scoped snapshot owned by #851 and +leave a clear pre-dispatch boundary where #880 can independently skip work +without introducing another EC cache. + +## Request-Scoped KV Snapshot + +Introduce a snapshot type tied to one EC ID. It must distinguish: + +- lookup not attempted; +- authoritative missing row; +- present row with `KvEntry` and an optional usable generation; +- lookup failure. + +The failed state is a marker rather than a clone of `Report`, because the state +must travel through cloneable response extensions. The original error is logged +at the lookup boundary. Consumers degrade without retrying a failed lookup on +the hot path. + +The EC ID association prevents a snapshot from being reused after orphan +recovery rotates the active ID. A present snapshot with a generation supplies +the initial CAS input to the next update. The current Fastly insert API reports +only written or precondition failed; it does not return the generation produced +by a successful write. Consequently, a successful mutation retains the updated +in-memory entry but marks its generation unavailable. The next writer can still +use that entry for read-only decisions, but must perform one refresh lookup +before another CAS. A CAS precondition failure likewise causes a fresh lookup, +merge, and bounded retry. + +## Origin and Auction Scheduling + +Before consuming the downstream publisher request, build a bodyless auction +request snapshot containing the original method, URI, version, and headers. +This is an in-process compatibility view, not an outbound request: providers +continue to receive the same client-facing request shape through +`AuctionContext` and must not observe the origin-rewritten URI or Host header. +The existing provider-specific outbound allowlist remains authoritative. For +example, Prebid copies only selected browser headers and applies its configured +consent-cookie forwarding policy; internal and hop-by-hop headers are not newly +forwarded by this snapshot. Consent-denied auctions do not dispatch at all. + +When an EC-capable publisher request needs a snapshot and +`PlatformHttpClient::supports_concurrent_fanout()` is true: + +1. Build the base auction request and client-request snapshot. +2. Rewrite and start the publisher-origin request with `send_async`. +3. Read the EC KV row once while the origin is in flight. +4. If auction-eligible, decorate and dispatch the auction using the + client-request snapshot. +5. Await the pending origin request. + +For eager implementations where `send_async` completes the upstream request +before returning, retain dispatch-before-origin ordering. Cloudflare and Spin +must not wait for the complete origin response before starting their auction. +On Fastly, real-browser document navigations with an active EC and configured +graph preload the snapshot even when auctions are disabled, no slots match, or +consent prevents auction dispatch. Their lookup still occurs after the origin +has started, so orphan detection and finalization remain available without +placing the read before origin start. Non-document publisher requests do not +preload and cannot trigger orphan rotation. Routes that do not proxy a +publisher origin leave the snapshot not-read; finalization may perform its +existing lazy lookup for EID ingestion, while orphan recovery remains restricted +to real-browser document navigations and explicit withdrawal remains +route-independent. Non-EC publisher requests retain the ordinary origin send +path. + +Normal `generate_if_needed` creation seeds a generation-unavailable present +snapshot with the exact `KvEntry` successfully added to KV. It does not +pre-apply EID cookies in the generation layer. On a document navigation, the +single origin-overlapped preload refreshes that snapshot and obtains the +generation needed by finalize, so ordinary first-generation behavior joins the +same read lifecycle without an extra pre-send lookup. + +Origin-start failure returns the existing proxy error without performing KV or +auction work. Auction dispatch failure remains best-effort and does not prevent +the already-started origin response from being returned. Origin failure after +auction dispatch preserves the existing abandoned-auction telemetry behavior +and emits its terminal event exactly once. + +## Auction EID Resolution + +Auction resolution accepts the request snapshot rather than a KV graph. A +present live entry resolves registered partner IDs. Missing, failed, not-read, +or tombstone state produces no server-side EIDs and does not fail the auction. +Client-provided EIDs continue through the existing merge and consent gate. + +## Orphaned Cookie Recovery + +An incoming EC ID cannot be authenticated in full. The HMAC prefix is shared by +all IDs behind the same normalized IP, while the suffix is random and unsigned. +Consequently, neither format validation nor HMAC-prefix validation authorizes +recreating the incoming key. + +On an authoritative missing snapshot during consent-granted, real-browser +document-navigation EC finalization: + +1. Generate a fresh EC ID using the current generation path. +2. Parse, validate, deduplicate, and apply request EID-cookie updates to the new + in-memory `KvEntry` before persistence. +3. Atomically add that complete entry in one write. +4. Only after the add succeeds, replace the active EC ID and emit the new + cookie. +5. Return a snapshot associated with the replacement ID and updated entry. Its + generation is unavailable because `Add` does not return the new token. + +KV lookup failure is not a miss and must not rotate the cookie. A present +tombstone must never be revived. Explicit withdrawal runs before recovery and +continues to expire the cookie and write the authoritative tombstone. + +If creating the replacement row fails, retain fail-closed behavior: keep the +original active context for withdrawal bookkeeping, return a failed snapshot, +do not emit a replacement cookie, and do not create partner mappings. A random +suffix collision is handled by generating another fresh ID and retrying a small +bounded number of times; no existing key is overwritten or revived. + +Batch sync and generic partner upsert APIs continue to reject missing roots. +Only the trusted browser finalization flow can initiate orphan recovery. +Subresources and non-document integration requests never rotate an orphaned +cookie. + +## Withdrawal Semantics + +The invariant that an unverified incoming ID cannot create a root also applies +to withdrawal tombstones. The current unconditional tombstone overwrite can +create a new key for a forged cookie and must become existing-key-only: + +- an authoritative missing row is a no-op after expiring the browser cookie; +- a present row is tombstoned with its generation; +- a CAS conflict rereads and retries against the latest existing row; +- a row that disappears during retry is a no-op; +- a lookup failure expires the browser cookie but performs no KV write. + +This preserves withdrawal for real entries without turning arbitrary cookie +values into stored tombstones. Tombstone writes retain their 24-hour TTL and +empty identity payload. + +## Finalization Contract + +EC finalization accepts the request snapshot and returns an outcome containing +the current EC context and updated snapshot. Returning-user EID ingestion uses +the carried entry and generation for its first CAS attempt. It rereads only on +CAS conflict. After a successful write, it returns the updated entry with no +usable generation because the backend does not expose the new token. + +The updated in-memory entry must include partner IDs written during finalization +so post-send pull sync does not dispatch a partner that was just populated. +Cookie and cache-privacy behavior remains centralized in the existing finalize +and entry-point layers. + +Mutation outcomes contain only state known to be persisted. An unchanged merge +returns the original entry and generation. A successful write returns the +persisted updated entry with no generation. A store error or exhausted CAS +retry returns a failed snapshot rather than claiming request-local updates were +stored. Pull sync does not dispatch from failed state. + +## Pull Sync + +Pull sync receives the finalized snapshot and uses it for eligibility without +an initial KV lookup. Missing, failed, not-read, or tombstone snapshots do not +dispatch pull sync. + +Valid partner responses are collected across every HTTP concurrency batch into +one request-wide set of `PartnerIdUpdate` values and merged in one final bulk +CAS operation. Draining a network batch never writes KV. When the finalized snapshot still +has a usable generation, the uncontended case performs one write and no +additional read. When finalization already wrote the row, pull sync uses its +updated entry for eligibility, collects responses, then performs one refresh +lookup to obtain the new generation before its bulk CAS. A conflict rereads the +latest entry, rejects a tombstone, re-merges every collected update, and retries +within the existing bound. Pull sync never creates a missing root. + +Rate limiting, URL allowlisting, bearer-token handling, response-size limits, +UID validation, concurrency limits, and best-effort post-send behavior remain +unchanged. + +## Adapter Surface + +Fastly owns the configured EC KV graph and carries the snapshot through +`EcRequestState` and `EcFinalizeState`. The graph itself is rebuilt at the entry +point as it is today; only cloneable entry data and generation travel in response +extensions. + +Axum, Cloudflare, and Spin currently call the shared publisher path without an +EC KV graph. They must continue compiling and retain their existing auction and +origin behavior. Scheduling tests cover both concurrent and eager HTTP-client +implementations so future adapters cannot accidentally regress auction timing. + +## Error and Privacy Invariants + +- A KV error never becomes an authoritative miss. +- No unverified incoming EC ID can create a KV root. +- A cookie is emitted only after its backing row exists. +- Tombstones are never converted to live entries by enrichment. +- CAS conflicts re-merge rather than overwrite concurrent data. +- Consent-denied requests expose no EC or EID data. +- Post-send failures never change the client response. +- Logs use redacted EC identifiers through the existing `log_id` helper. + +## Test Strategy + +Use strict red-green-refactor cycles. Add focused unit tests for snapshot state, +snapshot-bound EID resolution, CAS reuse and conflict retry, orphan rotation, +failure versus miss, tombstone protection, and bulk pull updates. Include a +finalize-write-then-pull test proving eligibility uses the updated entry and the +pull writer refreshes the unavailable generation exactly once. Cover successful +pull responses spanning multiple HTTP concurrency batches and prove they still +produce one request-wide KV merge. Add publisher scheduling tests using +recording HTTP/KV collaborators to prove origin starts before the lookup only +for truly concurrent clients and that bidders see the original downstream +request. Cover origin-start failure with no KV/auction work, auction dispatch +failure followed by a successful origin response, and origin completion failure +with exactly one abandoned-auction terminal event. Add withdrawal tests for +present, missing, conflicting, and failed snapshot states, plus mutation-failure +tests proving unpersisted request-local IDs never appear in returned snapshots. + +Run targeted core tests after each behavior change, followed by adapter suites, +formatting, and target-matched clippy according to `CLAUDE.md`. + +## Success Criteria + +- An eligible Fastly navigation starts the publisher origin before its EC KV + lookup and SSP dispatch. +- Auction, finalize, and pull eligibility share one normal-path KV read. A + subsequent pull write may require one generation-refresh read when finalize + already wrote the row. +- Successful pull-sync responses use one bulk write rather than one RMW cycle + per partner. +- Orphaned cookies recover through a newly generated, KV-backed EC ID. +- KV errors and tombstones remain fail-closed. +- Eager adapters do not delay auction dispatch behind origin completion. +- All target-specific tests, formatting checks, and clippy checks pass.

Named routes, integration proxies, and request-filter short circuits no longer reach EC finalization with recovery authorized, so a blocked or non-publisher response cannot rotate an identity. - Never downgrade an in-request Add-confirmed Present snapshot on a preload refresh miss, and confirm an authoritative miss with a second read (after the origin round trip) before rotating. A single eventually-consistent edge miss can no longer rotate a valid identity; a now-visible row is adopted instead. - Preload the origin-overlapped snapshot with the unfiltered active EC ID while keeping the consent-filtered ID for auction identity, so consent-withdrawn navigations keep the withdrawal CAS off the post-origin latency path. - Resolve the initial usable snapshot outside the CAS retry counter in both partner upsert and conditional tombstoning, so a generation-unavailable or refreshed snapshot keeps all five write attempts. - Defer /auction and page-bids identity-graph reads until a live auction actually runs with a partner registry, avoiding billable KV reads that cannot be consumed. Add tests for four-conflicts-then-fifth-write CAS, transient Add->Missing->Present confirmation, and recovery-eligibility lifecycle across named routes, filter short circuits, and origin-start failures. --- .../trusted-server-adapter-fastly/src/app.rs | 95 +++++++++++++- .../src/auction/endpoints.rs | 10 +- crates/trusted-server-core/src/ec/finalize.rs | 86 ++++++++++++- crates/trusted-server-core/src/ec/kv.rs | 120 +++++++++++++++--- crates/trusted-server-core/src/publisher.rs | 43 +++++-- 5 files changed, 320 insertions(+), 34 deletions(-) diff --git a/crates/trusted-server-adapter-fastly/src/app.rs b/crates/trusted-server-adapter-fastly/src/app.rs index 12b2fd164..afee58770 100644 --- a/crates/trusted-server-adapter-fastly/src/app.rs +++ b/crates/trusted-server-adapter-fastly/src/app.rs @@ -407,7 +407,13 @@ fn build_ec_request_state( match EcContext::read_from_request_with_geo(settings, req, services, geo_info.as_ref()) { Ok(mut context) => { context.set_device_signals(device_signals); - context.set_recovery_eligible(is_real_browser && is_navigation_request(req)); + // Orphan-recovery eligibility is intentionally left false here. + // Authorizing it during generic pre-routing would let named + // routes and request-filter short circuits (e.g. a DataDome + // challenge) reach EC finalization and rotate an identity off a + // non-publisher response.

Both call sites now derive the section through `CreativeOpportunitiesConfig::section_for_path` and render the template, and `ExpectedSlot`/`ConfiguredJson` carry an optional unit path so an over-limit dynamic render is reported rather than silently matched against the wrong unit. Also resolves the outstanding review findings on these paths: - Write the operator config through a same-directory temp file, fsync, and rename, so a failed write cannot truncate `trusted-server.toml`. - Validate TLS certificates in both audit browser sessions; opting out now requires `--danger-accept-invalid-certs`. - Refuse a redirect that leaves the requested origin during verify unless `--allow-cross-origin-redirect` is passed, so another origin's evidence cannot satisfy `--strict`. - Reject page patterns the runtime cannot compile before they reach the file, through a new shared `compile_page_pattern` in core. - Reject `creative_opportunities` declared in a form the line-based splice cannot edit, instead of appending a duplicate table. - Drop non-integer GPT sizes in the collector so one fluid size cannot fail deserialization of the whole evidence payload. - Escape control characters in page-controlled text written to the terminal. --- .../src/ad_templates/compare.rs | 54 ++++- .../src/ad_templates/expected.rs | 86 +++++++- .../src/ad_templates/output.rs | 77 ++++++- .../commands/audit/ad_template_collector.js | 34 ++- .../src/commands/audit/ad_templates.rs | 195 +++++++++++++++-- .../src/commands/audit/browser.rs | 31 ++- .../src/commands/audit/collector.rs | 9 + .../audit/generate/browser_collector.rs | 5 + .../src/commands/audit/generate/mod.rs | 203 +++++++++++++++++- .../src/commands/audit/generate/slot_toml.rs | 141 +++++++++++- .../src/commands/audit/mod.rs | 7 + .../src/commands/audit/page.rs | 13 +- .../src/commands/config/ad_templates.rs | 35 ++- .../src/creative_opportunities.rs | 71 +++--- docs/guide/cli.md | 21 ++ 15 files changed, 903 insertions(+), 79 deletions(-) diff --git a/crates/trusted-server-cli/src/ad_templates/compare.rs b/crates/trusted-server-cli/src/ad_templates/compare.rs index 18e47fb0b..215a6a300 100644 --- a/crates/trusted-server-cli/src/ad_templates/compare.rs +++ b/crates/trusted-server-cli/src/ad_templates/compare.rs @@ -251,13 +251,27 @@ pub fn compare_page_evidence( for slot in expected { let resolved = resolve_dom(&evidence.dom_ids, &slot.div_id);

From 07b37a1f0a2a4436437b57bf5b634dd3cf330aa7 Mon Sep 17 00:00:00 2001 From: prk-Jr Date: Mon, 17 Aug 2026 10:47:37 +0530 Subject: [PATCH 153/315] Verify generated ad-template config before it replaces the operator file `ts audit ad-templates generate` derived everything it wrote from a live, page-controlled ad stack and never checked the result, so several reachable inputs produced a config that cannot load. An unloadable `trusted-server.toml` is not a degraded ad stack: `build_state` fails and the adapter answers every route from the startup error router, so the whole site returns 500 once pushed. Add a write-side gate that runs the candidate through `Settings::from_toml`, the same `finalize_deserialized` chain the runtime uses at startup. It runs on the `--dry-run` path too, so a clean preview is now evidence the config loads. When the target config was already unloadable before the run, the gate reports that as a warning instead of blaming this run, so a freshly bootstrapped file carrying placeholder secrets can still be updated. Close the three reachable paths at their source as well: - Skip a scraped slot whose ad-unit path contains `{` or `}`. The path is a template and there is no escape syntax, so a literal brace either fails config load or is silently reinterpreted as a placeholder. - Skip a slot whose div id normalizes to nothing (a wholly ephemeral id such as a React SSR marker). An empty `div_id` fails config load, and as a runtime prefix it would bind the slot to the first id-bearing element on the page. - Refuse to create a `[creative_opportunities]` section with no GAM network id rather than writing one that omits the required key. This is reachable because the network id is only recovered from an all-digit leading segment, which an MCM child-network path does not have. --- .../src/commands/audit/generate/gpt_slots.rs | 89 ++++++++++++++ .../src/commands/audit/generate/mod.rs | 72 +++++++++++ .../src/commands/audit/generate/slot_toml.rs | 34 +++++- .../src/commands/audit/generate/validate.rs | 112 ++++++++++++++++++ 4 files changed, 304 insertions(+), 3 deletions(-) create mode 100644 crates/trusted-server-cli/src/commands/audit/generate/validate.rs diff --git a/crates/trusted-server-cli/src/commands/audit/generate/gpt_slots.rs b/crates/trusted-server-cli/src/commands/audit/generate/gpt_slots.rs index fea34dd1f..365a5b696 100644 --- a/crates/trusted-server-cli/src/commands/audit/generate/gpt_slots.rs +++ b/crates/trusted-server-cli/src/commands/audit/generate/gpt_slots.rs @@ -130,6 +130,9 @@ fn slot_from_registry(entry: &CollectedGptSlot, page_has_prebid: bool) -> Option if is_multi_slot_div(&entry.div_id) { return None; } + if !is_usable_unit_path(&entry.gam_unit_path) { + return None; + } let formats: Vec<(u32, u32)> = entry .sizes .iter() @@ -140,6 +143,14 @@ fn slot_from_registry(entry: &CollectedGptSlot, page_has_prebid: bool) -> Option return None; } let div_stem = normalize_div_stem(&entry.div_id); + // Normalization truncates at the first ephemeral marker, so a div id that is + // *entirely* ephemeral (`_R_9sl…`, or exactly `-container`) reduces to the + // empty string.

Nothing calls this yet; `run_update_slots` is unchanged. `AuditCollector` gains a defaulted `collect_pages` that streams each page to a sink, so every existing implementor keeps working and the caller can fold a page into its evidence and drop the DOM immediately instead of holding every serialization at once. The browser collector overrides it to launch Chrome once for the whole crawl: a cold start plus a fresh profile dominates the cost of a multi-page run, and the shared profile carries a bot-protection clearance cookie earned on the first page across the rest of the walk. Page discovery reads the hydrated DOM rather than the served markup, because an app-router page keeps its link graph in the framework payload — parsing raw HTML finds only a fraction of a site's sections. Sitemaps are fetched from inside the open page via `fetch` plus `DOMParser`, which inherits the session's cookies and Chrome's TLS fingerprint, gets transparent gzip and XML parsing, and so needs no new Rust dependency. `crawl_plan` turns links and sitemap entries into a bounded page set: one landing page and one article per section, ranked by whether navigation and the sitemap corroborate each other, capped by section and page budgets. Sections dropped for budget are reported rather than silently omitted. Same-origin is enforced on links and on sitemap entries alike, since a `Sitemap:` directive can name any host and the crawl carries operator cookies. --- .../src/commands/audit/generate/analyzer.rs | 12 + .../audit/generate/browser_collector.rs | 217 +++++++- .../src/commands/audit/generate/collector.rs | 78 +++ .../src/commands/audit/generate/crawl_plan.rs | 521 ++++++++++++++++++ .../src/commands/audit/generate/mod.rs | 5 + 5 files changed, 823 insertions(+), 10 deletions(-) create mode 100644 crates/trusted-server-cli/src/commands/audit/generate/crawl_plan.rs diff --git a/crates/trusted-server-cli/src/commands/audit/generate/analyzer.rs b/crates/trusted-server-cli/src/commands/audit/generate/analyzer.rs index dc1ea9ffe..06d784b7a 100644 --- a/crates/trusted-server-cli/src/commands/audit/generate/analyzer.rs +++ b/crates/trusted-server-cli/src/commands/audit/generate/analyzer.rs @@ -286,6 +286,8 @@ mod tests { resource_type: Some("Script".to_string()), }], gpt_slots: Vec::new(), + links: Vec::new(), + sitemap_locs: Vec::new(), warnings: vec!["partial settle".to_string()], }; @@ -323,6 +325,8 @@ mod tests { script_tags: Vec::new(), network_requests: Vec::new(), gpt_slots: Vec::new(), + links: Vec::new(), + sitemap_locs: Vec::new(), warnings: Vec::new(), }; @@ -341,6 +345,8 @@ mod tests { script_tags: Vec::new(), network_requests: Vec::new(), gpt_slots: Vec::new(), + links: Vec::new(), + sitemap_locs: Vec::new(), warnings: Vec::new(), }; @@ -366,6 +372,8 @@ mod tests { resource_type: Some("script".to_string()), }], gpt_slots: Vec::new(), + links: Vec::new(), + sitemap_locs: Vec::new(), warnings: Vec::new(), }; @@ -401,6 +409,8 @@ mod tests { ], network_requests: Vec::new(), gpt_slots: Vec::new(), + links: Vec::new(), + sitemap_locs: Vec::new(), warnings: Vec::new(), }; @@ -432,6 +442,8 @@ mod tests { script_tags: Vec::new(), network_requests: Vec::new(), gpt_slots: Vec::new(), + links: Vec::new(), + sitemap_locs: Vec::new(), warnings: Vec::new(), }; diff --git a/crates/trusted-server-cli/src/commands/audit/generate/browser_collector.rs b/crates/trusted-server-cli/src/commands/audit/generate/browser_collector.rs index 077c5550a..b1c504cd5 100644 --- a/crates/trusted-server-cli/src/commands/audit/generate/browser_collector.rs +++ b/crates/trusted-server-cli/src/commands/audit/generate/browser_collector.rs @@ -13,7 +13,8 @@ use url::Url; use which::which; use crate::commands::audit::generate::collector::{ - AuditCollector, CollectedGptSlot, CollectedPage, CollectedRequest, CollectedScriptTag, + AuditCollector, CollectedGptSlot, CollectedLink, CollectedPage, CollectedRequest, + CollectedScriptTag, ControlFlow, PageSink, }; use crate::error::{CliResult, report_error}; @@ -49,14 +50,56 @@ impl AuditCollector for BrowserAuditCollector { )) })?; - runtime.block_on(collect_page_via_browser_async(target_url, cookies)) + runtime.block_on(async { + let mut collected = None; + with_browser( + std::slice::from_ref(target_url), + cookies, + &mut |_, result| { + collected = Some(result); + Ok(ControlFlow::Stop) + }, + ) + .await?; + collected.unwrap_or_else(|| Err(report_error("browser session produced no page"))) + }) + } + + fn collect_pages( + &self, + targets: &[Url], + cookies: &[(String, String)], + on_page: PageSink<'_>, + ) -> CliResult<()> { + if targets.is_empty() { + return Ok(()); + } + let runtime = Builder::new_current_thread() + .enable_all() + .build() + .map_err(|error| { + report_error(format!( + "failed to build Tokio runtime for browser audit: {error}" + )) + })?; + + runtime.block_on(with_browser(targets, cookies, on_page)) } } -async fn collect_page_via_browser_async( - target_url: &Url, +/// Launches one browser, walks `targets` on it, and hands each result to `sink`. +/// +/// One launch for the whole crawl rather than one per page: a cold Chrome start +/// plus a fresh profile dominates the cost of a multi-page run.

From 73ac39c1cecfd9b38edccc4e479aefd41312b8d8 Mon Sep 17 00:00:00 2001 From: prk-Jr Date: Mon, 17 Aug 2026 11:04:55 +0530 Subject: [PATCH 155/315] Accumulate cross-page slot evidence for ad-template generate Template inference needs the set of observations per slot, not one snapshot: a single page cannot distinguish a literal ad-unit path from a templated one, so the divergence across pages is the only signal available. Add the table that holds it. Nothing calls this yet. Slots are keyed on the normalized div stem, since raw GPT div ids carry per-render framework hashes and would otherwise look like a new slot on every page. Three reconciliations happen here and nowhere else: - Formats union across pages. A size that renders only on article pages, such as a 300x600 rail, has to survive alongside the homepage's sizes; taking the first page's list would silently narrow the slot. - Divergent unit paths are retained as separate rows rather than collapsed, because discarding them is what makes templating impossible. - Network ids must agree. Two GAM networks in one crawl means the pages are not one property, so this is a hard error naming both rather than a guess that would bid against the wrong inventory. Pages that yield no slots are recorded rather than dropped, so a caller can recognise a bot challenge serving interstitials and refuse to write a half-empty config. --- .../src/commands/audit/generate/evidence.rs | 372 ++++++++++++++++++ .../src/commands/audit/generate/mod.rs | 1 + 2 files changed, 373 insertions(+) create mode 100644 crates/trusted-server-cli/src/commands/audit/generate/evidence.rs diff --git a/crates/trusted-server-cli/src/commands/audit/generate/evidence.rs b/crates/trusted-server-cli/src/commands/audit/generate/evidence.rs new file mode 100644 index 000000000..e1b1bf81b --- /dev/null +++ b/crates/trusted-server-cli/src/commands/audit/generate/evidence.rs @@ -0,0 +1,372 @@ +//!

Nothing calls this yet. A wrong template makes a publisher bid against inventory that does not exist, which is worse than a narrow literal path, so this refuses rather than guesses. Three rules carry that: - `{network_id}` binds positionally to unit segment 0 and only when that segment already equals the resolved id. Substring replacement would rewrite `/123/sports123/home` into `/{network_id}/sports{network_id}/home`. - Exactly one unit segment may vary. Zero proves nothing and stays literal; two means the unit tracks a dimension the request path cannot supply, such as a device or geo split, and is refused with that reason. - Two pages must witness both a different derived section and a different unit segment before anything is templated. Round-trip verification cannot supply this: a single observation is reproduced equally well by a literal path, a `{network_id}`-only template, and a `{section}` template, so only variation distinguishes them. `section_segment` is chosen by partitioning observations into pages that have a section segment and pages that do not, the latter fixing `section_root`. An index that cannot be witnessed is rejected, an unwitnessed root leaves the path literal rather than guessing, and two indices that both fit are ambiguous and template nothing. Every accepted template is then replayed through the runtime's own `render_gam_unit_path` and `derive_section` against every observation, so a section slug the path cannot reproduce is caught and downgraded. `derive_section` becomes public for exactly this: the check has to use the runtime's derivation rather than a second implementation that could drift from it. --- .../src/commands/audit/generate/mod.rs | 1 + .../commands/audit/generate/unit_template.rs | 841 ++++++++++++++++++ .../src/creative_opportunities.rs | 6 +- 3 files changed, 847 insertions(+), 1 deletion(-) create mode 100644 crates/trusted-server-cli/src/commands/audit/generate/unit_template.rs diff --git a/crates/trusted-server-cli/src/commands/audit/generate/mod.rs b/crates/trusted-server-cli/src/commands/audit/generate/mod.rs index 649a57047..c90235649 100644 --- a/crates/trusted-server-cli/src/commands/audit/generate/mod.rs +++ b/crates/trusted-server-cli/src/commands/audit/generate/mod.rs @@ -5,6 +5,7 @@ mod crawl_plan; mod evidence; mod gpt_slots; mod slot_toml; +mod unit_template; mod validate; use std::collections::BTreeSet; diff --git a/crates/trusted-server-cli/src/commands/audit/generate/unit_template.rs b/crates/trusted-server-cli/src/commands/audit/generate/unit_template.rs new file mode 100644 index 000000000..790a89859 --- /dev/null +++ b/crates/trusted-server-cli/src/commands/audit/generate/unit_template.rs @@ -0,0 +1,841 @@ +//!

Nothing calls the new code yet. `page_patterns` expands the paths a slot was observed on into globs. Each witnessed section contributes a pair, because one glob cannot cover both halves: `*` crosses `/` in this dialect, so `/news/*` matches `/news/a/b` but not the bare `/news` landing page, and emitting only the star form would silently drop the landing page from the slot. Nothing extrapolates past a witnessed section, so a crawl that never visited `/reviews` never claims it. `replace_key_in_section` can only rewrite a key that is already present, so it could not add `section_root` or `section_segment` to a config that predates them, which is every config a first templated run touches. Add `upsert_key_in_section`, which inserts immediately after the section header so the new key lands in the section's scalar block rather than after a subtable, where TOML would read it as belonging to that subtable instead. `splice_creative_slots` now takes the section keys as a struct rather than a bare network id. It omits `section_root` and `section_segment` entirely unless a slot actually templated: both are `deny_unknown_fields` additions, so writing them into a config that does not need them would make it unloadable by an older binary for no benefit. --- .../src/commands/audit/generate/mod.rs | 10 +- .../commands/audit/generate/page_patterns.rs | 137 +++++++++ .../src/commands/audit/generate/slot_toml.rs | 275 ++++++++++++++++-- 3 files changed, 391 insertions(+), 31 deletions(-) create mode 100644 crates/trusted-server-cli/src/commands/audit/generate/page_patterns.rs diff --git a/crates/trusted-server-cli/src/commands/audit/generate/mod.rs b/crates/trusted-server-cli/src/commands/audit/generate/mod.rs index c90235649..8c1e793ee 100644 --- a/crates/trusted-server-cli/src/commands/audit/generate/mod.rs +++ b/crates/trusted-server-cli/src/commands/audit/generate/mod.rs @@ -4,6 +4,7 @@ pub(crate) mod collector; mod crawl_plan; mod evidence; mod gpt_slots; +mod page_patterns; mod slot_toml; mod unit_template; mod validate; @@ -546,7 +547,14 @@ pub(crate) fn run_update_slots( replace, ); let rendered_slots = render_slots(&merged); - let updated = splice_creative_slots(&existing, network_id.as_deref(), &rendered_slots)?; + let updated = splice_creative_slots( + &existing, + &slot_toml::CreativeSectionKeys { + network_id: network_id.as_deref(), + ..slot_toml::CreativeSectionKeys::default() + }, + &rendered_slots, + )?; // Everything above is derived from a live, page-controlled ad stack, so the // candidate has to clear the runtime's own load path before it can replace diff --git a/crates/trusted-server-cli/src/commands/audit/generate/page_patterns.rs b/crates/trusted-server-cli/src/commands/audit/generate/page_patterns.rs new file mode 100644 index 000000000..70b18a6ae --- /dev/null +++ b/crates/trusted-server-cli/src/commands/audit/generate/page_patterns.rs @@ -0,0 +1,137 @@ +//!

The flow is collect root, plan the crawl from its links and sitemap, walk the planned pages on one browser, fold each into the evidence table, infer, then merge, render, splice and validate as before. Page patterns now come from the sections a slot was actually seen on, so a slot scraped from one article serves its whole section instead of that single URL. Failure handling follows what the evidence can support. A page that will not collect is reported and skipped, because one blocked page should not discard the sections that worked. But if more than a quarter of crawled pages yield no slots the run refuses outright: that is the signature of bot protection serving challenge interstitials, and writing from it would silently narrow the operator's slot set. Pages disagreeing about the GAM network id is likewise a refusal rather than a guess. A run that templates prints the deploy-ordering contract, because the config it just wrote is not rollback-safe: `section_root` and `section_segment` are `deny_unknown_fields` additions, so an older binary rejects the whole config and serves an error on every route. `--max-pages` and `--max-sections` bound the crawl; `--max-pages 1` restores single-page behavior exactly, and an explicit `--page-pattern` still applies to every slot and skips pattern inference. `run_update_slots` takes a request struct, since a nine-argument signature could not absorb the crawl bounds. Removes `default_page_pattern`, superseded by section-derived patterns, and narrows the single-page `merge_slots` path to test scaffolding. --- .../src/commands/audit/generate/collector.rs | 8 - .../src/commands/audit/generate/crawl_plan.rs | 10 +- .../src/commands/audit/generate/evidence.rs | 5 - .../src/commands/audit/generate/mod.rs | 675 ++++++++++++++---- .../commands/audit/generate/page_patterns.rs | 5 - .../src/commands/audit/generate/slot_toml.rs | 50 ++ .../commands/audit/generate/unit_template.rs | 5 - .../src/commands/audit/mod.rs | 37 +- 8 files changed, 635 insertions(+), 160 deletions(-) diff --git a/crates/trusted-server-cli/src/commands/audit/generate/collector.rs b/crates/trusted-server-cli/src/commands/audit/generate/collector.rs index 625ac660e..e11cf2634 100644 --- a/crates/trusted-server-cli/src/commands/audit/generate/collector.rs +++ b/crates/trusted-server-cli/src/commands/audit/generate/collector.rs @@ -14,10 +14,6 @@ pub(crate) type PageSink<'a> = #[derive(Debug, Clone, Copy, PartialEq, Eq)] pub(crate) enum ControlFlow { /// Collect the next target. - #[allow( - dead_code, - reason = "constructed by run_update_slots once it orchestrates the crawl" - )] Continue, /// Stop the crawl without an error (budget reached, challenge rate exceeded).

A single-profile crawl cannot see that: it infers a template that is correct for the profile it used and silently wrong for every other impression, with nothing in the data to say so. This was the one unmitigated risk in the inference design. `--profiles desktop,mobile` walks every planned page once per profile, each with its own viewport and user agent, folding all of it into one evidence table. The user agent matters as much as the viewport here — ad stacks branch on it, so emulating size alone can still return desktop ad units on a phone-sized page. No new refusal logic was needed. Two profiles disagreeing produce two ad-unit paths for a single page, which is already the structural refusal inference applies to a unit that varies by something the request path cannot derive. The slot is still written, with its div and formats intact, but with no `gam_unit_path`: no path at all is better than one that is wrong on mobile, and the runtime falls back to the default unit rather than bidding on a unit that does not exist. Desktop-only stays the default, so the extra crawl is opt-in. --- .../audit/generate/browser_collector.rs | 126 +++++++++++++++-- .../src/commands/audit/generate/mod.rs | 132 ++++++++++++++++-- .../src/commands/audit/mod.rs | 53 ++++++- 3 files changed, 284 insertions(+), 27 deletions(-) diff --git a/crates/trusted-server-cli/src/commands/audit/generate/browser_collector.rs b/crates/trusted-server-cli/src/commands/audit/generate/browser_collector.rs index b1c504cd5..eead2d49a 100644 --- a/crates/trusted-server-cli/src/commands/audit/generate/browser_collector.rs +++ b/crates/trusted-server-cli/src/commands/audit/generate/browser_collector.rs @@ -4,6 +4,7 @@ use std::time::Duration; use chromiumoxide::ArcHttpRequest; use chromiumoxide::browser::{Browser, BrowserConfig}; use chromiumoxide::cdp::browser_protocol::network::CookieParam; +use chromiumoxide::handler::viewport::Viewport; use futures::StreamExt as _; use serde::Deserialize; use tempfile::TempDir; @@ -32,8 +33,98 @@ const RESOURCE_TIMING_BUFFER_WARNING_THRESHOLD: usize = 250; const RESOURCE_TIMING_BUFFER_WARNING: &str = "browser resource timing buffer reached its default size; some network assets may be missing"; -#[derive(Default)] -pub(crate) struct BrowserAuditCollector; +/// A device the crawl can emulate. +/// +/// Publishers routinely serve different GAM ad units per device +/// (`/network/desktop/news` vs `/network/mobile/news`).

Cover what the crawl does, what it writes, and the two things an operator cannot discover from the output alone. The first is when the command declines to generalize. A wrong ad-unit template makes a publisher bid against inventory that does not exist, so the command prefers a narrow literal path over a plausible guess, and the table says which situations produce which outcome — including the cases that fail the run outright, such as a crawl where bot protection served mostly challenge pages. The second is deploy ordering. A config carrying `section_root` or `section_segment` is not rollback-safe: a binary predating ad-unit templating rejects those keys, and the rejection fails the whole configuration load rather than just the ad-template section, so every route serves an error. Ship the template-aware binary first, push second, and do not roll back while that config is live. --- docs/guide/cli.md | 129 ++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 129 insertions(+) diff --git a/docs/guide/cli.md b/docs/guide/cli.md index e0baac367..b0aeb612b 100644 --- a/docs/guide/cli.md +++ b/docs/guide/cli.md @@ -138,6 +138,135 @@ ts audit generate https://publisher.example --force The legacy `ts audit ` form remains a compatibility alias for artifact generation.

The guards exist for runs that went wrong, so that is exactly when the reasons matter. Notes are now drained as soon as the crawl finishes, ahead of the refusals, and each page's warnings are attributed to its path. Also name the failure that has no warning of its own. Bot protection commonly answers with 200 and a challenge document rather than a 4xx, so the status check passes, the page settles cleanly, and it simply appears to run no ad stack — indistinguishable from a publisher who genuinely has none, though the operator's next move differs completely. A page carrying almost no scripts and no recognised integrations is now called out as a probable challenge, with the advice to supply a current cookie. Verified against a live protected origin: the run previously reported only that no slots were found; it now identifies the interstitial and says what to do. --- .../src/commands/audit/generate/mod.rs | 74 +++++++++++++++++-- 1 file changed, 66 insertions(+), 8 deletions(-) diff --git a/crates/trusted-server-cli/src/commands/audit/generate/mod.rs b/crates/trusted-server-cli/src/commands/audit/generate/mod.rs index d31030ec7..d74a22e71 100644 --- a/crates/trusted-server-cli/src/commands/audit/generate/mod.rs +++ b/crates/trusted-server-cli/src/commands/audit/generate/mod.rs @@ -549,7 +549,7 @@ pub(crate) fn run_update_slots( let root_url = root.final_url().unwrap_or_else(|_| target_url.clone()); let mut table = evidence::EvidenceTable::default(); let mut notes = Vec::new(); - fold_collected(&mut table, &root_url, &root)?; + fold_collected(&mut table, &root_url, &root, &mut notes)?; // One page per section is enough: ad slots repeat per section, so the crawl // is sized by the publisher's taxonomy rather than its catalogue. @@ -563,7 +563,7 @@ pub(crate) fn run_update_slots( if index > 0 { let repeat = first_collector.collect_page(&root_url, request.cookies); match repeat { - Ok(page) => fold_collected(&mut table, &root_url, &page)?, + Ok(page) => fold_collected(&mut table, &root_url, &page, &mut notes)?, Err(error) => notes.push(format!("skipped `{root_url}` on {label}: {error}")), } } @@ -581,8 +581,17 @@ pub(crate) fn run_update_slots( )); } + // Emit what the crawl learned before any refusal below can return early. + // The guards exist precisely for runs that went wrong, so that is when the + // per-page reasons matter most. + emit_notes(out, &mut notes)?; + if table.is_empty() { - return cli_error("no ad-template slots were discovered on any crawled page"); + return cli_error(format!( + "no ad-template slots were discovered on any of the {} crawled page(s); \ + see the notes above for what each page reported", + table.pages().len() + )); } guard_challenge_rate(&table)?; @@ -624,10 +633,7 @@ pub(crate) fn run_update_slots( // preview looked fine" would not be evidence that the config loads. notes.extend(validate::check_candidate(&updated, &existing)?); - for note in ¬es { - writeln!(out, "note: {note}") - .map_err(|error| report_error(format!("failed to write command output: {error}")))?; - } + emit_notes(out, &mut notes)?; if policy.is_some() { writeln!( out, @@ -661,13 +667,65 @@ pub(crate) fn run_update_slots( .map_err(|error| report_error(format!("failed to write command output: {error}"))) } +/// A page carrying fewer scripts than this is not a real publisher page. +/// +/// A production page runs dozens: the ad stack, analytics, consent, and the +/// site's own bundles.

A dead cookie fails on the first page, so that shape points at the session being flagged during the run rather than at the credential. Two contributors, both worth correcting regardless of that diagnosis. The crawl issued its navigations back to back. That is discourteous to the origin on its own terms, and request pacing is among the signals bot protection scores, so an unpaced crawl invites the challenge that empties the rest of the run. `--page-delay-ms` now spaces them, defaulting to 750ms. Headless Chrome is trivially detectable, so an origin that serves the real page to a normal browser may answer the same request headless with a challenge. `--headful` runs a visible browser for the cases where that is the difference. Note that `BrowserConfig` defaults to the *old* headless mode, so simply not requesting new-headless yields a more detectable browser rather than a headful one. Both branches are explicit for that reason. --- .../audit/generate/browser_collector.rs | 73 +++++++++++++++++-- .../src/commands/audit/mod.rs | 18 +++++ 2 files changed, 86 insertions(+), 5 deletions(-) diff --git a/crates/trusted-server-cli/src/commands/audit/generate/browser_collector.rs b/crates/trusted-server-cli/src/commands/audit/generate/browser_collector.rs index eead2d49a..b4ef2badd 100644 --- a/crates/trusted-server-cli/src/commands/audit/generate/browser_collector.rs +++ b/crates/trusted-server-cli/src/commands/audit/generate/browser_collector.rs @@ -114,6 +114,10 @@ impl DeviceProfile { #[derive(Debug, Clone, Copy, Default)] pub(crate) struct BrowserAuditCollector { profile: Option, + /// Pause between page loads during a crawl. + page_delay: Duration, + /// Run a visible browser instead of a headless one. + headful: bool, } impl BrowserAuditCollector { @@ -122,6 +126,48 @@ impl BrowserAuditCollector { pub(crate) fn with_profile(profile: DeviceProfile) -> Self { Self { profile: Some(profile), + ..Self::default() + } + } + + /// Sets the pause between page loads. + /// + /// A crawl issues a dozen navigations in a row.

Two additions, found by debugging exactly that. Publishers gate slot definition behind their consent platform, and a fresh audit profile has no consent cookie, so the crawl never reaches `googletag.defineSlot` and the page looks like it has no ad stack at all. The audit browser now answers the two IAB interfaces every compliant platform exposes, TCF v2 and US Privacy, installed before any page script runs so the real platform finds them already defined. `gdprApplies: false` avoids fabricating a consent string and matches the signal genuinely out-of-scope traffic carries. `--no-assume-consent` observes the un-consented page instead. When the slot registry comes back empty, the run now reports what GPT actually looked like — whether the library reached `apiReady`, how many queued commands never drained, whether `pubads()` exists, and how many scripts the page ran. An empty registry has several very different causes, and the operator's next move differs for each. Against a local proxy this immediately distinguished "GPT never finished loading" from "this page has no ads", which no amount of re-running could have shown before. --- .../audit/generate/browser_collector.rs | 148 +++++++++++++++++- .../src/commands/audit/mod.rs | 10 ++ 2 files changed, 157 insertions(+), 1 deletion(-) diff --git a/crates/trusted-server-cli/src/commands/audit/generate/browser_collector.rs b/crates/trusted-server-cli/src/commands/audit/generate/browser_collector.rs index b4ef2badd..beb5da93d 100644 --- a/crates/trusted-server-cli/src/commands/audit/generate/browser_collector.rs +++ b/crates/trusted-server-cli/src/commands/audit/generate/browser_collector.rs @@ -118,6 +118,8 @@ pub(crate) struct BrowserAuditCollector { page_delay: Duration, /// Run a visible browser instead of a headless one. headful: bool, + /// Answer the consent APIs as a consenting reader. + assume_consent: bool, } impl BrowserAuditCollector { @@ -152,6 +154,15 @@ impl BrowserAuditCollector { self.headful = headful; self } + + /// Answers the IAB consent APIs so a gated ad stack initialises. + /// + /// See [`CONSENT_STUB_SCRIPT`] for what is answered and why. + #[must_use] + pub(crate) fn assume_consent(mut self, assume_consent: bool) -> Self { + self.assume_consent = assume_consent; + self + } } /// The browser-session knobs one crawl runs under. @@ -160,6 +171,7 @@ struct SessionSettings { profile: Option, page_delay: Duration, headful: bool, + assume_consent: bool, } impl BrowserAuditCollector { @@ -168,10 +180,97 @@ impl BrowserAuditCollector { profile: self.profile, page_delay: self.page_delay, headful: self.headful, + assume_consent: self.assume_consent, } } } +/// Answers the consent APIs as a consenting, non-GDPR reader. +/// +/// Publishers gate slot definition behind their consent platform, so a browser +/// with no consent cookie never reaches `googletag.defineSlot` and the audit +/// sees a page with no ad stack.

React also emits the lowercase `_r_0_` form client-side, and the token changes on every render, so a slot arrived as `ad-header-0-_r_0_` on one page and `ad-header-0-_r_8_` on the next. One logical slot fragmented into a new key per page: the written `div_id` would never match at runtime, and template inference saw no slot twice, so it had no variation to reason about and kept every path literal. Collapsing the lowercase form is what lets the crawl rediscover `/{network_id}/autoblog/{section}` from live evidence. Add `--browser-proxy` so the audit can run against a production hostname served locally, which keeps the page's origin, cookie scope, and any origin checks in the ad stack matching production rather than `localhost`. `--danger-accept- invalid-certs` covers a MITM certificate whose CA the throwaway browser profile does not trust. Note that chromiumoxide builds each Chrome flag by prefixing `--` to the arg key, so a pre-formatted `--flag=value` string becomes `----flag=value` and is silently dropped. Both the new proxy flags and the existing mobile user-agent override were written that way; the user-agent override had therefore never taken effect. Both now pass `(key, value)` pairs. --- .../audit/generate/browser_collector.rs | 65 +++++++++++++++++-- .../src/commands/audit/generate/gpt_slots.rs | 52 ++++++++++++++- .../src/commands/audit/mod.rs | 19 ++++++ 3 files changed, 127 insertions(+), 9 deletions(-) diff --git a/crates/trusted-server-cli/src/commands/audit/generate/browser_collector.rs b/crates/trusted-server-cli/src/commands/audit/generate/browser_collector.rs index beb5da93d..148bbf2aa 100644 --- a/crates/trusted-server-cli/src/commands/audit/generate/browser_collector.rs +++ b/crates/trusted-server-cli/src/commands/audit/generate/browser_collector.rs @@ -111,7 +111,7 @@ impl DeviceProfile { } /// Collects pages through a local Chrome, emulating one device profile. -#[derive(Debug, Clone, Copy, Default)] +#[derive(Debug, Clone, Default)] pub(crate) struct BrowserAuditCollector { profile: Option, /// Pause between page loads during a crawl. @@ -120,6 +120,10 @@ pub(crate) struct BrowserAuditCollector { headful: bool, /// Answer the consent APIs as a consenting reader. assume_consent: bool, + /// Route the browser through this proxy, as `host:port`. + proxy: Option, + /// Accept TLS certificates that do not validate. + accept_invalid_certs: bool, } impl BrowserAuditCollector { @@ -163,24 +167,50 @@ impl BrowserAuditCollector { self.assume_consent = assume_consent; self } + + /// Routes the browser through `proxy` (`host:port`). + /// + /// Lets the audit run against a production hostname served by a local + /// MITM proxy, so the page's origin, cookie scope, and any origin checks in + /// the ad stack match production rather than `localhost`. + #[must_use] + pub(crate) fn with_proxy(mut self, proxy: Option) -> Self { + self.proxy = proxy; + self + } + + /// Accepts TLS certificates that do not validate. + /// + /// Needed when a MITM proxy presents a certificate from a CA the browser + /// profile does not trust.

Ten were two placements repeated: an ad stack built its div ids from a per-render token, so the same placement arrived under a new key on every page. Written verbatim those ids match nothing at runtime, and the fragmentation also starves template inference, which needs to observe a slot more than once. Detect it from evidence rather than by pattern-matching token shapes, since each stack invents its own and the previous two forms already needed separate handling. Candidates share an identical ad-unit path and identical formats; what separates a fragmented placement from two legitimate siblings on one unit is co-occurrence. Real siblings appear together on a page, while fragments never do, because each page yields exactly one of them. Fragments are reported and skipped rather than written. The report names the observed ids and the stable prefix they share, so the operator can add the placement once with a prefix they know survives a render. That prefix is deliberately not written as a `div_id`: it reaches only as far as the observed tokens happen to agree, so it would match this crawl's ids and miss the next render's. Verified live: the run that previously wrote fourteen slots now writes the four real ones and explains the two it declined. --- .../src/commands/audit/generate/evidence.rs | 200 ++++++++++++++++++ .../src/commands/audit/generate/mod.rs | 35 ++- 2 files changed, 234 insertions(+), 1 deletion(-) diff --git a/crates/trusted-server-cli/src/commands/audit/generate/evidence.rs b/crates/trusted-server-cli/src/commands/audit/generate/evidence.rs index bfa004b94..b2404da54 100644 --- a/crates/trusted-server-cli/src/commands/audit/generate/evidence.rs +++ b/crates/trusted-server-cli/src/commands/audit/generate/evidence.rs @@ -61,6 +61,62 @@ impl SlotEvidence { } } +/// Slots grouped by the shape that would make them one placement: an identical +/// ad-unit path and an identical format set. +type SlotsByShape<'a> = BTreeMap<(String, Vec<(u32, u32)>), Vec<&'a SlotEvidence>>; + +/// Several observed slots that are really one placement under volatile div ids. +#[derive(Debug, Clone, PartialEq, Eq)] +pub(super) struct FragmentGroup { + /// The volatile div ids observed, in evidence order. + pub(super) div_ids: Vec, + /// The ad-unit path every fragment shared. + pub(super) unit_path: String, + /// The stable prefix the ids share, when they share a useful one. + /// + /// Offered to the operator as a starting point only.

Each exists because a live audit of a protected publisher failed without it, so the reason belongs alongside the flag. Consent gets its own section because the failure is silent. A publisher gates slot definition behind its consent platform, the audit runs in a throwaway profile with no consent cookie, and the result is a page that appears to have no ad stack at all — indistinguishable from one that genuinely has none. Also record that an empty slot registry now reports GPT's observable state, which is what separates "the library never loaded" from "this page has no ads". Proxy auditing gets a section because `ts dev proxy` is how a production hostname is served locally, and matching the production origin matters for cookie scope and for origin checks inside the ad stack. Note the caveat that a local Trusted Server injects its own configured slots, so a run through the proxy can rediscover config it already has.

The summary's explicitly out-of-scope pre-existing +partially-invalid `page_patterns` behavior is not expanded into this PR unless a +fix is required by another in-scope change. The PR description's stale legacy +alias sentence is corrected after the branch changes are published. + +Each reviewer suggestion is verified against the current code. A suggestion is +implemented when it is correct for this repository. Where repository evidence +contradicts a suggestion, the implementation retains the correct behavior and +the review response explains the evidence. + +## Design Principles + +- Preserve operator-authored configuration, comments, ordering, and unrelated + sections byte-for-byte wherever possible. +- Never print secrets or whole effective configuration documents as diagnostic + output. +- Never turn uncertain crawl evidence into a runnable fabricated ad-unit path. +- Treat browser navigation as a session, not a sequence of isolated launches. +- Keep `generate`, `verify`, static CLI commands, and runtime matching on shared + domain rules instead of parallel reimplementations. +- Bound all page-controlled data and browser operations. +- Use test-first changes for behavior corrections and minimal annotations for + code-quality-only corrections. + +## Component Design + +### 1. Configuration integrity and command output + +`slot_toml` will replace the line-oriented slot-boundary heuristic with a +TOML-aware edit strategy. The resulting document must preserve every top-level +item outside the managed creative-opportunity fields and preserve comments +adjacent to or between operator sections. Non-contiguous slot declarations, +multiline values, arrays whose continuation lines begin with `[`, trailing +comments, CRLF input, and inline-slot conversion receive regression coverage. +The updater will reject a candidate if preservation cannot be proven. + +Generation will re-read the source config immediately before the atomic write +and refuse to overwrite a concurrently edited file. `--dry-run` will emit only +the managed creative-opportunities change, never the complete config. Notes and +rollback warnings go to stderr so machine-readable stdout remains clean. Tests +will prove that dry-run leaves the source file byte-identical and does not expose +unrelated secret-bearing keys. + +Merge behavior remains add-only for operator-authored data: existing templated +unit paths are retained, newly observed formats are unioned, and multiple +discovered placements absorbed by one broad configured div prefix produce an +operator note. + +### 2. Crawl evidence and inference + +Inference will preserve evidence instead of silently collapsing it: + +- Non-ASCII shared-prefix computation uses UTF-8 byte boundaries. +- Same-page normalization collisions retain distinct raw placements and emit a + diagnostic rather than silently dropping formats. Numeric-only stable tokens + are not classified as hexadecimal hash noise. +- Multi-slot SRA request fallbacks are ignored when `dids` names more than one + slot. +- A page is considered empty only when no audited profile found slots there. +- Fragment detection requires stronger evidence: a useful shared prefix, or at + least three disjoint fragments. Ambiguous two-slot groups are retained with a + note. +- Locale landing paths are emitted literally when they are shorter than the + inferred section depth, and literal path segments are escaped before being + interpolated into globs. +- Refused template decisions are omitted from generated slots and surfaced with + their reasons. The documentation and tests will consistently describe these + cases as refusal, not literal fallback. +- The redundant witness rule is removed or made independently meaningful. The + actual crawler will support the section depth that inference can produce; + locale-prefixed behavior will not exist only in hand-built evidence tests. +- Dropped-section diagnostics are capped, percent-encoded paths are normalized + before filtering, and page-like extensions are classified consistently. + +The root page and section pages for a device profile are collected in one +browser session. Page analysis that parses full HTML is moved off the +current-thread CDP event pump. Each page/tab is closed on every success and +error path. + +### 3. Shared browser behavior + +The browser collectors will share executable discovery and launch/session +configuration. Browser options exposed to operators will have one meaning in +`page`, `verify`, and `generate`: Chrome override, settling, headful/headless +mode, device profile/viewport, proxy, consent assumption, cookies, and TLS +policy. + +`verify` will reuse one browser/runtime/profile across its URLs so clearance and +session state survive. The generic/legacy generator will default to the same +consent assumption as ad-template generation and expose the opt-out rather than +depending on `derive(Default)`. + +Cookie parameters are explicitly host-only with `Path=/`. A same-host +`http`-to-`https` upgrade is accepted with a redirect note; host changes, +downgrades, and unexpected port changes remain cross-origin refusals. Failure to +read or parse the final browser URL fails closed instead of substituting the +requested URL. + +Every post-navigation evaluation is time-bounded. The collector enlarges the +resource timing buffer before navigation, waits for an interactive or complete +document before accruing quiet time, honors sub-poll quiet windows, validates +`quiet <= max`, and reports saturation. Navigation load-event timeout is a +warning after a successful `goto`; it does not discard readable page evidence. +Evidence payload bytes and captured string lengths are capped before expensive +decode/allocation. + +Init-script and page-evaluation failures become explicit warnings or errors +rather than empty evidence. Promise-returning sitemap evaluation awaits its +result. Main-frame-only collection is disclosed when frames are skipped. + +The injected collector will be behavior-preserving: size pairs enforce the +`u32` range, the `googletag` setter is total, the unused non-variadic `cmd.push` +wrapper is removed, wrapping markers are closure-local/non-enumerable, and +page-derived warning text is terminal-safe. + +### 4. Runtime and static-command parity + +Expected-slot projection uses the runtime's renderability rule. Slots the +runtime omits for a path do not count as matched verification slots; diagnostics +state that the runtime omits the slot on that path rather than claiming the +whole config is rejected. + +Configured media type remains a typed `MediaType` through comparison and is +rendered to a string only at the output boundary. Slots that the phase-one +checker cannot confirm (video/native-only and out-of-page) are represented as +unconfirmable and do not fail `--strict`; genuinely partial or missing +confirmable slots still fail. Slot phase is absent when no evidence exists. +The server-side APS compatibility field no longer creates unconditional +client-side `fetchBids` warnings. + +Collector warnings are included in page results. Human output includes the +runtime expectation, gate summary, matched count, extra evidence, and warnings +already present in JSON. Output escaping covers Unicode bidi controls and all +config-derived strings. + +`explain` reports exactly the shared runtime gate result. Provider configuration +is a separate advisory. The unsupported `--edgezero-enabled` model and stale +legacy-fallback claim are removed because no runtime condition backs them. +Gate diagnostics consume the shared gate result instead of rebuilding lists by +hand. The hot runtime gate avoids heap allocation, the seven-boolean wrapper is +removed, and the consent tri-state is documented and exhaustively tested. + +`compile_page_pattern` becomes crate-private and a public validation-only API is +used by the CLI. Specific compile failures are retained in logs. HTTP methods +use `http::Method` parsing so CLI semantics match the runtime. + +### 5. CLI contracts, documentation, and CI + +Clap owns argument validation: URL parsing happens at the value parser, the +audit namespace uses help-on-missing-subcommand, `check` uses an argument group +and conflicts, and settle bounds are rejected during parsing. Parser tests cover +the visible command shapes and legacy restrictions. + +CI-oriented assertion failures exit 1; tool/configuration/navigation failures +exit 2. Assertion text is written directly and cannot disappear behind a log +filter. The guide documents all four `ts config ad-templates` commands, all +flags, shared config-loading flags, browser flags, consent/profile behavior, +dry-run output, and exit codes. + +Browser fixture CI either installs/resolves Chrome and requires the tests to +execute, or explicitly opts into a mode that fails when Chrome is unavailable; +it may not report success after silently skipping every browser assertion. + +All real-looking customer identifiers and names introduced by this PR are +replaced with fictional values in tests, comments, and documentation. Stale +module-level lint suppressions, inaccurate docs, assertion messages, enum +ordering, dead query matching, and orphaned comments are corrected without +unrelated cleanup. + +## Error Handling and Compatibility + +All new Rust fallible paths use the repository's existing `CliResult` / +`error-stack` conventions. Browser failures identify the operation and URL but +do not include cookies, configuration values, or page payloads. Best-effort +cleanup must not replace an earlier collection error. + +JSON compatibility is preserved where possible. New distinctions are additive +or correct semantically invalid fields: unconfirmable status is explicit, and +phase may be omitted when there was no evidence. Documentation is updated with +the exact wire behavior. + +## Verification Strategy + +Each behavioral issue follows red-green-refactor: + +1. Add the smallest unit, parser, orchestration, or fixture test reproducing the + review finding. +2. Run the narrow test and confirm the expected failure. +3. Implement the minimal correction. +4. Re-run the narrow test and the affected crate suite. + +Final verification runs the repository-required commands relevant to the +changed surface: CLI tests through `scripts/test-cli.sh`, target-matched Rust +tests, JS tests when the collector script changes, `cargo fmt --all -- --check`, +all target-matched clippy aliases, documentation formatting, and browser fixture +tests with an available Chrome. Any environment-dependent test that cannot run +is reported explicitly and is not described as passing. + +## Review Replies and Publication + +Changes are grouped into reviewable commits by component, then pushed to the PR +branch after final verification. Each inline reply is posted in its existing +thread and states the concrete change, relevant test, or evidence-backed reason +for retaining behavior. Replies avoid generic acknowledgements. Threads are not +replied to as fixed until the corresponding commit is visible on GitHub.

Non-blocking: - Adopt an inferred section policy when the config has none: a `{section}` slot without `section_root` cannot load, so there is no policy to preserve. - Note a followed root redirect; keep credentials, queries, and origins out of per-page notes and the cross-origin refusal. - Report per-page collection failures once and the consent stub once per run. - Collapse index-document links onto their section. - Expose the browser flags on `ts audit generate` and its legacy alias. - Move the dry-run "no changes" sentence to stderr and build the diff lazily. - Pace the crawl before announcing the page; scope audit cookies by origin. - Make the consent stub configurable and enumerable so a CMP that installs via `defineProperty` is not aborted, and the stub is not a fingerprint. Docs and debt: correct the strict-mode claim for sizeless out-of-page slots, document both new refusal classes and the stderr progress contract, drop the real publisher and vendor identifiers from the spec, order the manifest dependencies, and document the arms and fields that are unreachable or reserved. --- crates/trusted-server-cli/Cargo.toml | 4 +- .../src/ad_templates/compare.rs | 16 +- .../src/ad_templates/output.rs | 4 + crates/trusted-server-cli/src/app_config.rs | 2 +- .../commands/audit/ad_template_collector.js | 25 +- .../src/commands/audit/ad_templates.rs | 11 +- .../src/commands/audit/browser.rs | 58 ++- .../src/commands/audit/collector.rs | 23 + .../src/commands/audit/consent_stub.js | 9 +- .../audit/generate/browser_collector.rs | 135 +++--- .../src/commands/audit/generate/collector.rs | 22 +- .../src/commands/audit/generate/crawl_plan.rs | 190 +++++++- .../src/commands/audit/generate/evidence.rs | 88 +++- .../src/commands/audit/generate/gpt_slots.rs | 436 +++++++++++++----- .../src/commands/audit/generate/mod.rs | 136 +++++- .../src/commands/audit/generate/slot_toml.rs | 134 ++++-- .../commands/audit/generate/unit_template.rs | 9 +- .../src/commands/audit/mod.rs | 96 +++- .../src/commands/audit/page.rs | 81 +++- .../src/commands/config/ad_templates.rs | 12 +- docs/guide/cli.md | 51 +- .../2026-06-26-server-side-ad-template-cli.md | 9 +- .../2026-08-18-pr-823-review-resolution.md | 3 +- ...26-08-19-refuse-volatile-div-collisions.md | 8 +- ...6-08-18-pr-823-review-resolution-design.md | 8 +- ...9-refuse-volatile-div-collisions-design.md | 70 ++- 26 files changed, 1276 insertions(+), 364 deletions(-) diff --git a/crates/trusted-server-cli/Cargo.toml b/crates/trusted-server-cli/Cargo.toml index 20c454a70..e08114850 100644 --- a/crates/trusted-server-cli/Cargo.toml +++ b/crates/trusted-server-cli/Cargo.toml @@ -17,8 +17,8 @@ workspace = true [target.'cfg(not(target_arch = "wasm32"))'.dependencies] chromiumoxide = { workspace = true } clap = { workspace = true } -edgezero-core = { workspace = true } edgezero-cli = { workspace = true } +edgezero-core = { workspace = true } futures = { workspace = true } glob = { workspace = true } http = { workspace = true } @@ -30,9 +30,9 @@ serde_json = { workspace = true } similar = { workspace = true } tempfile = { workspace = true } tokio = { workspace = true } -tracing = { workspace = true } toml = { workspace = true } toml_edit = { workspace = true } +tracing = { workspace = true } trusted-server-core = { workspace = true } url = { workspace = true } which = { workspace = true } diff --git a/crates/trusted-server-cli/src/ad_templates/compare.rs b/crates/trusted-server-cli/src/ad_templates/compare.rs index a1dc271a1..48ab71f3e 100644 --- a/crates/trusted-server-cli/src/ad_templates/compare.rs +++ b/crates/trusted-server-cli/src/ad_templates/compare.rs @@ -45,11 +45,16 @@ pub struct GptSlotEvidence { pub phase: EvidencePhase, } -/// An `apstag.fetchBids` call observed on the page (spec §5.5). +/// An `apstag.fetchBids` call the page made, if any were recorded. +/// +/// The collector no longer hooks `apstag`: server-side APS configuration is +/// metadata rather than a client assertion, so a missing client call is not a +/// finding.

On a live crawl that dropped `ad-atf_sidebar-0` from the config even though its five observed ad-unit paths differ only in the section segment, and the reported reason ("used several ad-unit paths and none generalized") pointed at the wrong cause. `SlotAnalysis::RootUnwitnessed` now carries the varying segment, so such a slot templates against the config-level `section_root` another slot witnessed. That is safe because the slot's page patterns are derived from the paths it was seen on, all of which carry a section segment: `{section}` never falls back to the root for it. A note names the borrowed `section_root`. When *no* slot witnessed a root, nothing templates, and the diagnostic now says that the crawl never included a page without a section segment instead of blaming generalization. Verified against a live crawl: the sidebar is written with `/{network_id}/autoblog/{section}`, matches only its five sections, and does not match the root, while the previously written slots are unchanged. --- .../commands/audit/generate/unit_template.rs | 138 ++++++++++++++++-- docs/guide/cli.md | 24 +-- 2 files changed, 139 insertions(+), 23 deletions(-) diff --git a/crates/trusted-server-cli/src/commands/audit/generate/unit_template.rs b/crates/trusted-server-cli/src/commands/audit/generate/unit_template.rs index faf8ea67d..ed630e18f 100644 --- a/crates/trusted-server-cli/src/commands/audit/generate/unit_template.rs +++ b/crates/trusted-server-cli/src/commands/audit/generate/unit_template.rs @@ -96,9 +96,15 @@ enum SlotAnalysis { Static, /// Cannot be represented; carries the operator-facing reason.

A dedicated `LegacyBrowserOpts` mirrors the +seven generation browser fields and converts into `GenerateBrowserOpts` when the +legacy command is dispatched. Consequently, flags placed before a real audit +subcommand are rejected instead of parsed and ignored. + +Generation retains its established 750 ms quiet period and 12-second maximum +settle wait. Generation defaults have one source of truth shared by clap, +`GenerateBrowserOpts::default`, and `BrowserAuditCollector::default`; applying +parsed options must not silently shorten the collector's maximum. The generic +page/verification collector keeps its existing independent 10-second default. + +Redirect notes show the origin and path for both requested and final URLs. This +makes scheme and host changes visible without exposing URL userinfo, queries, or +fragments. + +## Root-Less Template Safety + +Template inference records which slot stems borrowed the config-level +`section_root` because those slots were never witnessed on a path without the +configured section segment. Such a template is safe only while its page patterns +are derived from the paths where the slot was observed. + +Operator-supplied `--page-pattern` values replace those derived patterns for +every slot. If inference contains any borrowed-root slot and explicit patterns +were supplied, generation fails before rendering or writing a candidate config. +The error identifies the affected slots, explains that explicit patterns cannot +prove the borrowed-root invariant, and directs the operator to remove +`--page-pattern`. Failing the command is preferable to silently omitting real +inventory or attempting an unsound glob intersection. + +When no config-level section policy can be inferred because every otherwise +templatable slot lacks a root witness, each affected slot's refusal reason names +that crawl gap rather than claiming that its paths failed to generalize. + +## Merge Policy + +An explicitly configured `section_segment` is operator intent even when +`section_root` is currently unset. If preserved `{section}` slots exist and an +inferred policy would change that configured segment, merge fails and requires +`--replace` for the migration. If the configured segment matches, or is unset, +the inferred `section_root` may be adopted so the previously incomplete config +becomes loadable. + +## Diagnostics and Early Validation + +Warnings produced while folding a collected page include the device-profile +label as well as the path. Identical warnings from desktop and mobile therefore +remain distinguishable. The consent-stub warning remains a single unscoped +run-level note, and site-wide discovery warnings remain deduplicated. + +The existing config is parsed as TOML before Chrome starts. A whole-document +syntax error is returned immediately; a valid document with settings unknown to +the CLI still permits extraction of `[creative_opportunities]`; and a present +but unreadable creative section remains an error. + +The volatile div-id token recognizer requires at least ten leading digits plus +an alphanumeric suffix. This continues to recognize timestamp-like generated +tokens while preventing an eight-digit calendar date followed by a stable +letter from causing a single-observation family refusal. + +## Consistency Corrections + +Tests pin the Rust evidence cap to the embedded JavaScript collector constant. +The terminal-escaping test claims only controls it can actually inject; URL's +own percent-encoding is covered by an exact final-URL assertion rather than +presented as evidence for terminal escaping. Existing code escaping the final +URL remains as defense in depth. + +The affected guide, prior volatile-collision spec and plan, documentation +comments, `expect` message, and method spacing are corrected to describe the +implemented behavior exactly. The root-less templating behavior and this review +resolution are documented by this design and its paired implementation plan. + +## Testing and Delivery + +Every behavioral correction starts with a focused regression test that fails on +the current branch. Tests cover hidden legacy flags, the 12-second generation +default, complete redirect notes, borrowed-root rejection with explicit +patterns, configured-segment preservation, profile-specific warnings, +whole-document TOML failure, the evidence-cap invariant, and the calendar-date +token control. + +After focused tests pass, verification runs the host-target CLI suite and +audit/generate tests, CLI clippy with warnings denied, Rust formatting, docs +formatting, and `git diff --check`. No GitHub replies or push are part of this +change unless separately requested.

It now returns a plain `format!` like its sibling branch, names the config file from the path the caller already holds, and leads with the guidance so the multi-line parse error trails unbroken. Blame the crawl for an unwitnessed `section_root` only when the crawl gap is what stopped inference. The per-slot reason rewrite was gated on `root_witness_missing` alone while the run-level note was gated on `diagnostics.is_empty()`, so a run that stopped on segment ambiguity told the operator to widen the crawl when the remedy is pinning `section_segment`. Give the page audit's settle defaults one source of truth: `BrowserOpts` and `BrowserCollector::new` now share `PAGE_SETTLE_*` instead of holding independent literals that nothing pinned equal. Also: the borrowed-root refusal says `div id(s)`, matching what it prints and distinguishing it from the run-level diagnostic's slot ids; the `--page-pattern` docs say the run fails rather than implying inference is retained; the hidden legacy alias carries `value_name = "URL"` so its rejection does not name a field absent from `--help`; and the `ad-templates generate` browser field is documented like its twin. Test hardening: a `Command::debug_assert` over the crate's `requires` argument ids, the parent-flag rejection pins `MissingRequiredArgument` rather than any error, the JS/Rust evidence cap test parses the declared value instead of matching punctuation, the hidden-flag help test covers all seven flags, and `audit_page_subcommand_parses` is renamed for the settle defaults it now protects. --- .../src/commands/audit/browser.rs | 24 +++--- .../src/commands/audit/collector.rs | 14 +++- .../src/commands/audit/generate/mod.rs | 9 ++- .../commands/audit/generate/unit_template.rs | 73 ++++++++++++++++++- .../src/commands/audit/mod.rs | 53 ++++++++++---- crates/trusted-server-cli/src/run.rs | 58 ++++++++++----- docs/guide/cli.md | 6 +- 7 files changed, 183 insertions(+), 54 deletions(-) diff --git a/crates/trusted-server-cli/src/commands/audit/browser.rs b/crates/trusted-server-cli/src/commands/audit/browser.rs index c8cbffddf..7d8757aae 100644 --- a/crates/trusted-server-cli/src/commands/audit/browser.rs +++ b/crates/trusted-server-cli/src/commands/audit/browser.rs @@ -19,6 +19,7 @@ use crate::ad_templates::compare::BrowserAdEvidence;

Its +default is false, preserving current crawl cost and side effects. When enabled, +every page on every selected device profile performs the same deterministic +stepped scroll used by the existing page audit: scroll to 33%, 66%, and 100% of +the document, pause between steps, return to the top, then wait for the page to +settle again before reading HTML, GPT registry entries, and network evidence. + +The browser collector carries the option as session configuration so root, +planned section, desktop, and mobile page loads all behave consistently. Scroll +evaluation failures are best-effort page warnings; they do not discard evidence +that was already available after the initial settle. + +The implementation will share the deterministic scroll primitive with the +existing browser audit rather than maintain a second sequence of scroll steps. +Verifier-only evidence-phase bookkeeping remains in the verifier call path. + +## Merge diagnostics + +During a normal merge, generation tracks which pre-existing configured slots +matched at least one discovered slot. After processing all discovered slots, it +reports every unmatched pre-existing slot in configuration order. Those slots +remain unchanged in the output. + +The diagnostic is explicit about the limits of negative crawl evidence. Its +human-readable form for a non-scrolling run is equivalent to: + +```text +note: preserved 2 configured slot(s) not observed during this crawl: ad-header-0, ad-fixed_bottom-0. Re-run with broader coverage or --scroll; use --replace only to intentionally prune them. +``` + +When the current run already used `--scroll`, the follow-up omits that redundant +suggestion and recommends broader page/profile coverage before intentional +pruning. + +No staleness diagnostic is emitted when all configured slots were rediscovered, +when there were no existing slots, or under `--replace`, because that mode does +not preserve unmatched slots. Matching uses the same reconciliation logic as +the merge itself, avoiding a second definition of slot identity. + +Diagnostics go to stderr through the existing generation-note path. Stdout +remains limited to the dry-run diff or successful write summary, so redirection +and machine comparison remain stable. + +## Safety and compatibility + +The default command behavior, merge result, and generated TOML remain unchanged +unless `--scroll` discovers additional evidence. The warning never mutates or +deletes operator configuration. It names only configured slot IDs and does not +include cookies, URL credentials, query strings, or fragments. + +Scrolling can trigger additional ad requests and publisher behavior, which is +why it remains explicit. Existing page-delay, settle-window, browser-proxy, +certificate, cookie, and device-profile behavior applies unchanged. + +## Tests + +CLI parsing tests cover `--scroll` and its false default. Browser-collector tests +use a deterministic local page that defines a GPT slot only after scrolling and +prove that generation captures it with the option enabled but not without it. +Existing browser lifecycle and settle tests continue to cover teardown and +timeouts. + +Merge unit tests cover multiple unmatched configured slots, stable diagnostic +ordering, partial rediscovery, full rediscovery, an empty existing config, and +`--replace`. Command-level tests verify that the warning reaches stderr while +stdout and the preserved generated configuration retain their existing +contracts. + +Verification will run the host CLI test suite and relevant Chrome-backed CLI +tests, followed by the repository-required formatting and CLI lint gates. A +manual dry run against Autoblog may be used when a fresh bot-protection cookie +and proxy are available, but network-dependent behavior is not a required CI +test.

A section page that redirected off the audited origin previously folded its slots, formats and ad-unit paths into the generated config, and a later device profile's own root redirect was never checked at all. Both sites now skip such a page with a path-only note, and the later profile stops counting it towards profile coverage, so the existing zero-coverage refusal still fires when every page is lost. Restrict slot prefix reconciliation to the operator's original configured slots. matching_slot_index searched the whole mutable merged list, so a slot appended during this run became a prefix candidate for later discoveries: ad-top absorbed a later ad-top-sidebar, discarding its unit path and provider state while emitting no broad-prefix diagnostic. Run additions now match by exact identity instead, making the result order independent. Replace the real publisher named in the scroll and staleness design document with generic wording, per the documentation policy in CLAUDE.md. Tests cover a redirected section page, a later-profile root redirect, and an order-sensitive merge with an unrelated existing slot alongside ad-top and ad-top-sidebar. Reverting the two production changes fails exactly these three tests and nothing else. --- .../src/commands/audit/generate/mod.rs | 176 +++++++++++++++++- .../src/commands/audit/generate/slot_toml.rs | 99 +++++++++- ...mplate-generate-scroll-staleness-design.md | 6 +- 3 files changed, 276 insertions(+), 5 deletions(-) diff --git a/crates/trusted-server-cli/src/commands/audit/generate/mod.rs b/crates/trusted-server-cli/src/commands/audit/generate/mod.rs index 77cd99ffa..800026d7c 100644 --- a/crates/trusted-server-cli/src/commands/audit/generate/mod.rs +++ b/crates/trusted-server-cli/src/commands/audit/generate/mod.rs @@ -585,6 +585,18 @@ pub(crate) fn run_update_slots( match collected { Ok(page) => { let final_url = page.final_url().unwrap_or_else(|_| url.clone()); + // The requested origin is the trust boundary for every + // page, not just the root: a section page that redirects + // away would otherwise contribute foreign slots, formats + // and ad-unit paths to the generated config. + if origin_changed(&target_url, &final_url) { + notes.push(format!( + "skipped `{}` on {first_label}: it left the audited origin for {}", + url.path(), + final_url.origin().ascii_serialization() + )); + return Ok(collector::ControlFlow::Continue); + } if let Err(error) = fold_collected( &mut table, @@ -1035,8 +1047,20 @@ fn crawl_sections( &mut |url, collected| { match collected { Ok(page) => { - successful_pages += 1; let final_url = page.final_url().unwrap_or_else(|_| url.clone()); + // Same boundary as the first profile, and it covers this + // profile's root page too: a cross-origin redirect is not + // a page this run may learn inventory from, so it must + // not count towards profile coverage either. + if origin_changed(root_url, &final_url) { + notes.push(format!( + "skipped `{}` on {profile_label}: it left the audited origin for {}", + url.path(), + final_url.origin().ascii_serialization() + )); + return Ok(collector::ControlFlow::Continue); + } + successful_pages += 1; if let Err(error) = fold_collected(table, &final_url, &page, profile_label, notes) { @@ -2243,6 +2267,156 @@ mod tests { ); } + #[test] + fn update_slots_skips_a_section_page_that_redirects_off_origin() { + // Only the root navigation was origin-checked before planning.

Problem + +On 2026-08-21 a production deployment (publisher redacted, `prospect-a.example`) showed +an episodic stall: for a window of roughly 40 minutes, every request that reached the +application path carried a uniform extra ~600 ms of Fastly `time-elapsed`, and then +recovered to 20-50 ms with no deploy or config change we could observe. `/health` +(2-4 ms, short-circuits before app construction) and `/_ts/debug/ja4` (6-9 ms, settings +load only) stayed fast throughout, so the stall lived between app construction and +response send. + +Attributing that window required a live probing session: route-by-route bisection, +cookie-deletion experiments, and an eight-agent code trace. The trace found no +unconditional await on the path that could cost 570 ms, and exactly two +config-conditional candidates (the pre-route request filter's synchronous verification +POST, and EC identity KV writes before send), plus one dependency shared by every +application route (two geo hostcalls per request). We could not tell which one stalled, +because nothing in the response says where server time went. + +The Compute CPU budget is ~50 ms per request, so a large `time-elapsed` strongly +suggests wall-clock time outside active guest CPU: dependency awaits are the leading +explanation, with platform scheduling and hostcall queueing as the residual ones. The +comparison figure here is the fronting delivery layer's `time-elapsed` Server-Timing +entry, observed at its deliver phase. Either way, these are exactly the numbers a +response can carry about itself. + +## 2. Goals + +1. Every normal application response attributes its own server time by phase in a + standard header. Browsers expose the values to same-origin JavaScript via + `PerformanceResourceTiming.serverTiming`, so RUM tooling that reads that API can + surface the breakdown. Whether a given vendor or the publisher's own monitoring + extension actually collects it is verified separately in rollout; the publisher + extension needs a small change to render it. +2. The same numbers flow to Tinybird so we hold p50/p95/p99 per phase, per route class, + per PoP, per deployed version, and a future stall window self-diagnoses in one query. +3. No additional awaited I/O before first byte. The pre-send cost is a handful of + monotonic clock reads, one small allocation at entry, and rendering one header; + telemetry emission happens strictly after the last body byte. + +Scope note: phases cover the application lifecycle after T0. The `/health` and +`/_ts/debug/ja4` short-circuits, config-store open failures, and request-conversion +failures bypass the lifecycle and emit nothing. Requests served entirely by the +fronting cache never reach the guest and produce neither header entries nor rows. + +## 3. Non-goals + +- No trailer-based Server-Timing for body-phase spans (browsers do not expose trailer + values to JavaScript). +- No per-filter naming in any emitted surface. The request-filter span is `ts-filter` + regardless of which filter runs; vendor identity stays out of headers and telemetry. +- No Cloudflare or Spin emission wiring in v1. Core collection is adapter-neutral; those + adapters can wire emission later without core changes. +- No Tinybird endpoint pipe and no rollup materialized views in v1. Grafana queries the + datasource through the ClickHouse connector, matching the auction dashboards; rollups + only if panel latency demands them. +- No sampling of the header. The header is all-traffic when enabled; only Tinybird rows + sample. +- No cross-request circuit breaker for telemetry emission. Compute runs one isolate per + request; there is no shared mutable state to hold breaker state. The controls are the + bounded per-request cost and the `access_sample_rate` lever (section 10). + +## 4.

Header rendering covers the first six + plus the stored total; the last two are row-only. +- Inner state: one fixed-size array of `Option` slots indexed by phase, + `t0: Instant`, `headers_ready_total: Option`, + `auction_wait_placement: Option` (`PreHeader` or `InStream`), + and `resp_bytes: Option`. Phases that repeat within a request (geo, KV) + accumulate by saturating addition into the same slot. +- `mark_headers_ready()`: stores `t0.elapsed()` once at the response-commit boundary, + unconditionally, before either emission flag is consulted. The header renders this + stored value as `ts-total`; the telemetry row reads the same stored value as + `time_elapsed_ms`. The two surfaces cannot disagree, and the row stays correct when + the header flag is off. Full request duration is captured separately as + `request_elapsed_ms`, snapshotted immediately after the body-stream drive returns and + before any other post-send work, so pull-sync and telemetry emission are never + included in it. +- Sharing: `RequestTimings` is a cheap-clone handle, `Arc>`. It crosses + three boundaries: adapter entry to core handlers, the streaming body closure (records + body-phase spans after the response object has been handed off), and the adapter's + post-send emission read. Access is exclusively `try_lock()`: a contended or + poisoned lock drops the sample immediately rather than waiting, so recording can + never delay a request. +- Recording API: `timings.record(Phase::Geo, dur)` and a scope guard + `timings.span(Phase::Origin)` that records on drop. Guards use saturating duration + math; a non-monotonic reading records zero rather than panicking. The auction-wait + recorder takes the placement explicitly so the two modes cannot be conflated. +- Rendering: `server_timing_value(&self) -> Option` produces + `ts-total;dur=41.2, ts-appbuild;dur=18.4, ts-filter;dur=9.1` with durations in + milliseconds at one decimal. Phases never recorded are omitted. Returns `None` when + `mark_headers_ready()` has not run. + +`Instant` is already used freely in the guest (`publisher.rs`, `auction/telemetry.rs`), +so no new clock abstraction is needed. + +## 6.

Consent-store reads pass through the same +decorator and are timed like any other store call. Included pre-send operations: EC +generation `create_or_revive`, identify-path graph reads and evaluation, finalize-path +`ingest_eid_cookies`/`upsert_partner_ids` and withdrawal tombstones, consent-store +reads on consent routes, and batch-sync graph access when it runs before send. +Explicitly excluded: pull-sync work, which runs strictly after `send_to_client` and is +invisible to both surfaces. The decorator measures store-call latency only: no value +passing through it is read, parsed, or recorded, and the emitted surfaces carry no +consent or identity payloads. This feature therefore needs no consent gate; it is the +site measuring its own infrastructure, not processing user data. The timings handle +reaches `ec_finalize_response` inside the graph it already receives; that function +keeps the repository maximum of seven arguments and does not gain an eighth. + +Row-only fields: + +| Field | Measures | Site | +| -------------------- | --------------------------------------------------------- | ------------------------------------------------ | +| `auction_wait_ms` | wait on the dispatched auction (placement varies by mode) | seam hold (streaming) or buffered finalizer wait | +| `body_mode` | `streamed` or `buffered` response assembly | set where the response body is built | +| `stream_ms` | headers committed to last body byte | adapter around the body-stream drive | +| `resp_bytes` | bytes written to the client body | same | +| `request_elapsed_ms` | T0 to immediately after the body-stream drive returns | post-send snapshot, before pull-sync | + +Auction-wait placement is not universal. On the ordinary streaming path the wait +happens at the `` seam inside the body stream and nests inside `stream_ms`. On +buffered paths (the Fastly shared-template authorized miss, which buffers the full +transform and auction before returning a response, and every Axum response) the wait +completes before headers commit. The row therefore carries `body_mode` plus +`auction_wait_placement` (`pre_header` or `in_stream`), and derivations are +conditional: + +- `in_stream`: `stream_other_ms = greatest(coalesce(stream_ms, 0) - coalesce(auction_wait_ms, 0), 0)`. +- `pre_header`: `auction_wait_ms` joins the pre-header phase set, and `stream_other_ms = coalesce(stream_ms, 0)`. + +`unattributed_ms = greatest(coalesce(time_elapsed_ms, 0) - (coalesce(appbuild_ms, 0) + +coalesce(filter_ms, 0) + coalesce(geo_ms, 0) + coalesce(kv_ms, 0) + +coalesce(origin_ms, 0) + coalesce(template_cache_ms, 0) + pre-header auction wait), 0)`. +Every phase column is nullable, so every query-time formula wraps each term in +`coalesce(column, 0)` and every subtraction in `greatest(..., 0)`; query tests cover +sparse phase combinations. + +## 7. Freeze point and header emission + +The freeze-and-emit point is `send_edgezero_response` (Fastly `main.rs`), immediately +before `response.into_parts()`. This is the single choke point every send path shares, +and it runs after everything that can still mutate the response: the router middleware, +entry-point finalize (`apply_finalize_headers`, asset-policy reapplication), EC +finalization and its KV work, and terminal filter/privacy effects. +`apply_finalize_headers` itself does not emit; the `HEADER_X_TS_FINALIZED` sentinel +marks middleware finalization, not header commitment, and must not be treated as the +timing boundary. + +At the freeze point, in order: `mark_headers_ready()` (unconditional), the +`AccessTelemetrySnapshot` build (unconditional, section 10), then, gated on +`observability.server_timing_enabled`, append one `Server-Timing` header from +`server_timing_value()`. Append semantics, never insert: an origin-supplied +Server-Timing survives, and the fronting delivery layer's own entries (`time-elapsed`, +`hit-state`) are additive per the header's list semantics. + +Header emission is conservative: it happens only when the response is conclusively +non-storable by any shared cache, meaning `Cache-Control` contains `private` or +`no-store` (the existing `cache_control_headers_are_private_or_no_store` predicate). +Anything else, including bare `max-age`, `s-maxage` without `private`, +heuristically-cacheable responses with no cache header at all, and anything a fronting +cache override might store, emits no header, because a stored object would replay one +request's timings for its full lifetime. The long-lived immutable `tsjs` asset route +is the concrete excluded case. The snapshot and the telemetry row are unaffected by +this skip, so excluded routes still report through Tinybird. + +The Axum adapter applies the same emission rule at its terminal point before response +serialization, with adapter-specific phase semantics (section 8a). + +## 8. Geo lookup dedupe (rider) + +Today every dispatched request pays two geo hostcalls for one answer: request-phase in +`build_ec_request_state` (`app.rs:410`) and response-phase in +`FinalizeResponseMiddleware` (`middleware.rs:83`, alternate site `main.rs:285`). + +Plain request extensions cannot carry the result out: the middleware moves the request +context into `next.run(ctx)` and holds only the response afterward. The resolved geo +travels on a dedicated `GeoLookupState` response extension, attached on every exit +path that attempted a lookup, including the asset fallback, which runs +`build_ec_request_state` and then returns without `EcFinalizeState` (which is why +`EcFinalizeState` is not an acceptable carrier). States: `NotAttempted`, +`Attempted(None)` (lookup ran and failed, do not retry), and `Resolved(GeoInfo)`. The +finalize path consumes the carried value and performs a live lookup only in the +`NotAttempted` state; those legitimate fallback lookups (admin, batch, error paths) +are themselves timed into `ts-geo` so degraded geo cannot hide inside +`unattributed_ms`. The 401 rule (`resolve_geo_for_response` skips lookup for +unauthorized responses) is preserved. + +## 8a. Adapter phase semantics + +The Fastly adapter is the reference implementation of the taxonomy. Axum differs +structurally and its emissions are defined accordingly rather than pretending parity: + +- `ts-appbuild` is absent: Axum builds application state once at startup. +- `body_mode` is always `buffered`: the Axum HTTP client buffers upstream bodies, so + `stream_ms` measures buffered-body write-out and `auction_wait_placement` is always + `pre_header`. +- The freeze point is an outer service wrapper around the `RouterService` inside + `AxumDevServer`, not router middleware: router-generated 404/405 responses bypass + router middleware, and middleware returns before Axum serializes the body. The + wrapper sees every response including router-generated ones; `/health` is excluded + by path match inside the wrapper. +- Axum emits the header only; no Tinybird rows in v1 (unchanged). + +Cloudflare and Spin: collection compiles, no emission wiring in v1 (unchanged). + +## 9. Access telemetry row + +Extends the reserved `tinybird/datasources/access_logs_raw.datasource`. + +Kept columns: `event_ts`, `method`, `status`, `time_elapsed_ms` (defined as the +`mark_headers_ready()` snapshot), `sample_rate`, `event_date`, 30-day TTL. + +Removed: raw `path`. Route identifiers like `/_ts/admin/ec/{id}` would otherwise put +EC identifiers into a 30-day dataset, and publisher paths carry unbounded cardinality +and user-generated content (search terms, usernames, emails in slugs). Replaced by +`route_template`: + +- Named routes: the matched route-table pattern verbatim, parameters left as + placeholders. +- Publisher fallback: a coarse fixed template, `/` plus the first path segment + restricted to a bounded allowlisted charset, plus `/*` when deeper (for example + `/news/*`). The auction-telemetry normalizer is explicitly not sufficient here: it + redacts long tokens but preserves short identifiers and arbitrary slugs. +- Tests are adversarial, not just the happy path: a literal EC identifier on the admin + route, an email address in a path segment, search-term-shaped segments, and + overlong segments must all normalize to bounded, content-free templates. + +Added columns (all dimension columns non-nullable with an `unknown` sentinel, because +ClickHouse sorting keys cannot contain nullable columns): + +``` +`service_id` LowCardinality(String), -- FASTLY_SERVICE_ID; immutable deployment identity +`publisher_domain` LowCardinality(String), -- matches auction schema +`env` LowCardinality(String), -- adapter-derived: production | staging | unknown +`route_class` LowCardinality(String), -- publisher_html | tsjs | integration_proxy | ec | auction_api | other +`route_template` String, -- bounded, normalized; replaces path +`body_mode` LowCardinality(String), -- streamed | buffered +`auction_wait_placement` LowCardinality(String), -- pre_header | in_stream | none +`appbuild_ms` Nullable(UInt32), +`filter_ms` Nullable(UInt32), +`geo_ms` Nullable(UInt32), +`kv_ms` Nullable(UInt32), +`origin_ms` Nullable(UInt32), +`template_cache_ms` Nullable(UInt32), +`auction_wait_ms` Nullable(UInt32), +`stream_ms` Nullable(UInt32), +`request_elapsed_ms` Nullable(UInt32), +`resp_bytes` Nullable(UInt64), +`template_cache_state` LowCardinality(String), -- from the typed response extension, not the public header +`country` LowCardinality(String), +`ts_version` LowCardinality(String), +`pop` LowCardinality(String) -- FASTLY_POP, 'unknown' when absent +``` + +The matched route pattern does not survive dispatch today, so a typed +`RouteMetadata` response extension carries `route_class` and `route_template`: each +named-route handler wrapper attaches its route-table pattern verbatim (handlers +serving multiple patterns attach the one that matched), and the fallback and tsjs +handlers attach their class plus the coarse template. The freeze point consumes the +extension; nothing reconstructs routes from a handler enum or path regex. + +Typed sources only: `env` is adapter-owned, derived from the same Fastly +`FASTLY_IS_STAGING` input that drives `x-ts-env` (`Settings` has no environment +field and does not gain one). `template_cache_state` comes from a typed response +extension, not the `x-ts-template-cache` header (operator-configured response +headers can override managed headers): the currently private +`TemplateCacheResponseState` in `publisher.rs` becomes a typed response extension, +and every state transition sets the managed header and the extension together so +the two can never drift. `service_id` and `pop` come from the Fastly environment. `cache_state` +from the reserved schema is dropped: the guest cannot observe the fronting cache, and +guest-visible cache behavior is already carried by `template_cache_state` and +`origin_ms`. Rows exist only for guest-handled requests; fronting-cache hits are +invisible by construction and the dashboard documentation says so. + +Sorting key: `(event_date, service_id, publisher_domain, env, route_class, pop, +status)`. Grafana time filtering uses `$__timeFilter(event_ts)` and every panel query +also carries an `event_date` predicate so the primary index prunes; rollout validates +the panel queries with `EXPLAIN` before the dashboard is committed. This replaces the +reserved key `(event_date, path, status, method)`. Rollout step 4 verifies whether the +reserved datasource was ever deployed to the remote workspace; if it was, this schema +ships as a versioned replacement datasource with a cutover, not an in-place edit. + +## 10. Emission mechanics + +- `AccessTelemetrySnapshot`: built unconditionally at the freeze point, before + `into_parts()` consumes the response. It captures method, status, route metadata + (from the `RouteMetadata` extension), and typed dimension states (`env`, + `template_cache_state`, geo country). It exists because nothing else survives to + post-send on every path: the request is consumed by dispatch, the response by + `into_parts()`, and `EcFinalizeState` is absent on asset, admin, and error paths. +- The emitter's transport context is adapter-owned and route-independent: the + Events API target (backend spec, secret store name, dataset, token secret, sample + rate) derives from settings once at entry in `main.rs`, and the HTTP client is the + adapter's stateless platform client. Asset, admin, and error responses therefore + emit without `RuntimeServices` or `EcFinalizeState`. +- `send_edgezero_response` returns a delivery outcome instead of `()`, with + per-mode semantics because the two body paths observe different things. Streamed + bodies: a counting writer reports bytes written and distinguishes complete, + partial (truncated), and error outcomes. Buffered bodies: `send_to_client()` + returns no delivery result, so the byte count is captured from the body length + before the send and the outcome is complete-on-return with no partial detection; + `body_mode` in the row keeps the two regimes distinguishable in analysis. +- Ordering after the body-stream drive returns: snapshot `request_elapsed_ms` first, + run the existing pull-sync dispatch unchanged, then telemetry emission last, so + pull-sync is never delayed behind the ingest await and never included in + `request_elapsed_ms`. +- Sampling: uniform per-request decision against `tinybird.access_sample_rate`. No + client stickiness. Sampled-out requests are silent; every other drop (row build + failure, send failure, non-2xx) logs one warning naming the reason. There is no + cross-request warning suppression (per-request isolates hold no shared state); the + overload controls are the 2 s bounded await, the single-warning-per-request cap, and + `access_sample_rate` pushed down by config as the operational abort lever. Ingest + health is monitored from the Tinybird side via ingestion freshness on the + datasource, which catches quarantine and schema rejection that per-request warnings + cannot. +- Transport: one NDJSON row to the Tinybird Events API: same `api_host`, reserved + `access_dataset` and `access_token_secret`, 2 s first-byte and between-bytes + timeouts, `max_body_bytes` guard, no retry. +- Delivery confirmation: unlike the auction sink, which starts `send_async` and drops + the pending response (it runs before delivery completes and cannot afford to wait), + the access emitter runs after the client has the full response and therefore awaits + the bounded ingest response and validates 2xx. A non-2xx or timeout logs a warning + with the status. +- Budget: at `access_sample_rate = 1.0` this adds one backend request per request to + the service, after delivery; during a Tinybird outage each such request holds its + sandbox for up to the bounded timeout. The sample rate is the budget control; 1.0 is + a diagnosis setting, not a steady state, and rollout treats sustained emission + warnings as the signal to dial it down. +- Axum adapter: emits the header only; no Tinybird rows in v1. + +## 11. Dashboard and query model + +No endpoint pipe in v1. Grafana queries `access_logs_raw` directly through the +ClickHouse connector with `$__timeFilter(event_ts)` plus an `event_date` predicate, +matching the auction dashboards. + +Dashboard: a new standalone `grafana/dashboards/edge-performance.json` in the +telemetry repo (`trusted-server-tinybird`), performance only, no panels shared with +the revenue and auction dashboards. Panels: + +- Phase percentiles (p50/p95/p99) by `route_class`, per phase column. +- Stacked phase breakdown over time using the non-overlapping set: `appbuild_ms`, + `filter_ms`, `geo_ms`, `kv_ms`, `origin_ms`, `template_cache_ms`, pre-header + auction wait (where `auction_wait_placement = 'pre_header'`), and derived + `unattributed_ms`. In-stream auction wait and derived `stream_other_ms` chart in a + separate body-phase panel and never stack with pre-header phases. +- PoP split, `ts_version` overlay, template-cache state rates. +- Stall panel: rows with `request_elapsed_ms > 500` (post-body total, so body-only + stalls are caught) grouped by dominant phase, where `unattributed_ms` competes as a + phase so the panel cannot confidently blame a small measured span while most time is + uninstrumented. + +All derivations use the `coalesce`/`greatest` forms from section 6; query tests cover +sparse phase combinations and both `auction_wait_placement` modes. + +Sampling semantics for every aggregate: `sample_rate` must be operationally stable +within any queried window. Quantile panels filter strictly to a single `sample_rate` +value. Volume panels weight each row by `1.0 / sample_rate` (the inverse-probability +estimator is `sum(1.0 / sample_rate)` over emitted rows; `count() / rate` is valid +only when the query is already filtered to one rate). Pooled unweighted quantiles +across a rate change are documented as invalid. + +## 12. Config surface + +```toml +[observability] +# Append TS phase timings to the Server-Timing response header. +server_timing_enabled = false # example default +``` + +New `ObservabilitySettings` struct with the single boolean, default off, standard +environment override (`TRUSTED_SERVER__OBSERVABILITY__SERVER_TIMING_ENABLED`). +Collection has no flag: the flags gate the two emission surfaces independently. + +Tinybird flag structure: `tinybird.enabled` today arms the auction sink by itself, so +"enable Tinybird for access telemetry" would silently enable auction emission too. The +master flag is demoted to transport-only (host, store, credentials), and each emitter +gets its own switch: a new `tinybird.auction_enabled` defaulting to `true` (preserving +current behavior for existing configs) and the reserved `tinybird.access_enabled` +defaulting to `false`. A settings test locks the decoupling in both directions. + +Validation when `access_enabled = true`: `tinybird.enabled`, non-empty `api_host`, +non-empty `secret_store`, `access_dataset`, and `access_token_secret`, a positive +`max_body_bytes`, and `access_sample_rate > 0`. An armed-but-silent configuration +(`access_enabled = true`, `access_sample_rate = 0`) is a configuration error, not a +valid state; disabling is done with the flag, not the rate. + +Rollback and compatibility, because `Settings` is `deny_unknown_fields`: + +- Deployment order is binary first, config second. Rollback order is config first + (remove the `[observability]` table and any new tinybird keys), binary second. A + config containing the new fields must never be pushed while a pre-observability + binary can still run. +- Config serialization omits the table when it equals the default, so round-tripping a + config through tooling does not inject a field an older binary rejects. A + compatibility test asserts the serialized default config parses under the previous + schema. +- The environment-variable overlay cannot create a missing leaf, so the key ships + present-but-false in the base operator TOML (the same pattern the GPT integration + documents in `trusted-server.example.toml`) and is flipped by config push. + +## 13. Error handling + +- Recording is infallible: saturating math, lock-failure drops the sample, no panics. +- Header rendering failure (defensive `HeaderValue::from_str` error) logs and skips + the header. +- Row emission failure logs one warning naming the reason and drops the row. The + response has already been delivered; there is nothing to degrade. + +## 14. Testing + +- Core unit tests: phase accumulation, saturating math, `mark_headers_ready()` + idempotence and both-surface consistency, render format (one decimal, omission of + unrecorded phases), row serialization shape, auction-wait placement recording. +- Adapter tests (Fastly via Viceroy, Axum native): header present and well-formed on a + conclusively-private publisher route with the flag on; absent with the flag off; + absent on the shared-cacheable tsjs route and on a bare `max-age` response with the + flag on; exactly one TS-owned metric set (a single `ts-total`) with every + pre-existing Server-Timing value preserved, across all send paths; `ts-kv` captures + EC finalize work (proving the freeze point sits after it). +- Body-mode tests: ordinary streaming (in-stream wait nested in `stream_ms`), + Fastly shared-template authorized miss (buffered, pre-header wait), and Axum + (always buffered), each asserting placement and non-negative derivations. +- Geo dedupe: finalize consumes `Resolved`; no retry on `Attempted(None)`; live + lookup only on `NotAttempted`; fallback lookups timed into `ts-geo`; asset-fallback + path carries `GeoLookupState` without `EcFinalizeState`; 401 skip preserved. +- Route template: adversarial normalization tests (literal EC identifier on the admin + route, email address in a segment, search-term segments, overlong segments) all + producing bounded content-free templates. +- Settings: the access validation matrix including the armed-but-silent rejection; + auction/access flag decoupling in both directions; the former rejection test becomes + the wiring test; the serialized-default-config compatibility test against the + previous schema. +- Sink tests: `RecordingHttpClient` pattern; assert URI, NDJSON body shape, token + header, 2xx validation and warning on non-2xx, skip when sampled out, ordering after + pull-sync. +- Query tests: derivation formulas against sparse rows and both placements. + +## 15. Rollout and verification + +1. Land collection + freeze point + header emission behind the flag, off everywhere. + Full CI gate. +2. Staging deploy with the flag on. Delivery-layer verification is two-sided: a + pass-through request confirming the appended Server-Timing survives the fronting + VCL, and a MISS-then-HIT replay against a cacheable route confirming no stale + timing header is ever served from cache. Fallback if the VCL clobbers the header: a + one-line VCL change on the delivery service, or mirroring the value to + `x-ts-timing` while that lands. +3. Production flag on. Confirm + `performance.getEntriesByType('navigation')[0].serverTiming` shows `ts-*` entries + in a real browser session, and separately confirm what the publisher's RUM tooling + actually collects; the publisher monitoring extension renders it only after a small + change on their side. +4. Verify whether `access_logs_raw` exists in the remote Tinybird workspace. If yes, + ship the schema as a versioned replacement with cutover; if no, edit in place. + Validate the dashboard panel queries with `EXPLAIN` against the sorting key. Then + land the row schema, sink, and settings changes; sample at 1.0 during stall + diagnosis with ingestion-freshness monitoring on the datasource; then the + dashboard. +5. Success criterion: the next stall window is attributable from one response header + or one dashboard query, with no live probing session. + +## 16. Overhead + +Roughly ten monotonic clock reads, two stored snapshots, and one ~130-byte header per +request; one sampled HTTP POST with a bounded await after the response has fully +streamed. No allocation in the hot path beyond the one `Arc` at entry, the +`AccessTelemetrySnapshot` at the freeze point, and the rendered header string. + +## 17. Decisions and open questions + +- **Public exposure is a decision, not an open question.** The header is all-traffic + when enabled. Rationale: values are durations only; the delivery layer already + exposes `hit-state` and `time-elapsed` publicly on every response; filter vendor + identity is masked; emission is restricted to conclusively-private responses so no + cache can replay stale timings. Revisit (quantization or gating) only if a concrete + abuse surfaces. +- The fronting delivery layer's Server-Timing pass-through is unverified until the + first staging deploy (step 2). This is the only known external dependency. +- Body-phase capture threads the timings handle into the streaming closure in + `publisher.rs`; the exact seam is an implementation-plan detail, with the constraint + that a dropped handle (error paths, early client disconnect) must still yield a + valid row with null body-phase fields and a recorded delivery outcome. +- The stall window itself remains unattributed until this ships. If it recurs first, + the bisection runbook from 2026-08-21 (cookie-free curl UA request, static-asset + path versus HTML path) is the fallback.

Instead: + +- Provider instances are defined under `[auction.providers.*]`. +- OpenRTB 2.6 is the only protocol implemented in the first version. +- A provider selects an OpenRTB profile that owns nonstandard request and response semantics. +- Trusted Server integrations may register profiles through a compile-time Rust registry. +- A central bidder registry routes each client-requested bidder to exactly one provider. +- Provider configuration is compiled and validated at startup into an immutable auction plan. +- The runtime orchestrator operates only on compiled provider plans and normalized auction data. + +This redesign changes provider registration, routing, request construction, and response normalization. It deliberately preserves existing auction economics, privacy enforcement, signing behavior, creative delivery, mediation, and telemetry unless a structural change is required to support the new provider architecture. + +> **Core principle:** Configuration defines provider instances. Rust code registers +> tested protocols and profiles. A compiler turns configuration into an immutable +> plan. The orchestrator executes that plan without knowing about Prebid Server, +> APS, or any specific exchange. + +## Goal + +Allow operators to register any endpoint that conforms to the supported OpenRTB 2.6 subset without adding a new provider implementation. + +The same architecture must fully replace the current Prebid Server and APS auction providers while preserving their required behavior through OpenRTB profiles. + +## Problem + +The current system models Prebid Server and APS as statically named provider implementations. Each implementation combines several concerns: + +- Provider identity and enablement. +- OpenRTB request construction. +- Provider-specific request extensions. +- HTTP transport and backend registration. +- Timeout handling. +- OpenRTB response parsing. +- Provider-specific validation. +- Creative interpretation. +- Diagnostics. + +This causes several constraints: + +- Only one instance of each statically named provider can be registered. +- Adding a standards-compliant OpenRTB endpoint still requires Rust provider code. +- Provider identity, protocol behavior, and upstream seat identity are not cleanly separated. +- Slot routing is implicit and differs by provider. +- Deploy-time validation and runtime registration maintain separate provider inventories. +- Prebid browser integration concerns are coupled to server-side provider configuration. + +The auction orchestrator itself already has useful behavior for parallel execution, deadlines, partial failures, winner selection, mediation, and telemetry. The redesign should preserve those strengths while replacing provider construction and routing. + +## Design Decisions + +### Configuration-first boundary + +“Configuration-first” means a standards-compliant endpoint within the supported OpenRTB 2.6 subset can be onboarded using configuration alone. + +It does not mean: + +- Arbitrary OpenRTB variants can be programmed through configuration. +- New protocols can be implemented through templates or scripts. +- Provider-specific behavior can use unrestricted JSON transformations. + +If an endpoint requires nonstandard semantics, those semantics are implemented as ordinary Rust profile behavior registered in this repository. + +### Protocol scope + +The architecture may support additional protocols later, but the first version implements only: + +```text +openrtb-2.6 +``` + +No runtime plugin, sandboxed WASM, dynamic native extension, or configuration scripting system is included. + +### Provider configuration location + +All server-side auction-provider instances are configured under: + +```toml +[auction.providers.*] +``` + +Browser and page integrations remain under: + +```toml +[integrations.*] +``` + +A browser integration may be disabled while its server-side auction profile is used by a provider. + +### Profile model + +The first version exposes one profile selection per provider rather than a configurable list of capabilities. + +Profiles are registered Rust implementations with narrow responsibility for protocol-specific request and response semantics. The initial profiles are: + +- `standard` +- `prebid-server` +- `aps` + +Internally, profile implementations may share smaller components. Those components are not exposed as a public capability-composition language in the first version. + +### Current behavior preservation + +The redesign preserves the current behavior of: + +- Trusted Server request signing, using the existing signing protocol. +- Consent extraction, privacy enforcement, and identity gating. +- Highest decoded-price winner selection. +- Current floor enforcement. +- Current USD assumptions. +- Optional external mediation. +- Creative sanitization and delivery. +- APS rendering behavior. +- Prebid Cache handling. +- Existing auction telemetry and provider outcome semantics. + +The project does not redesign these systems. + +### Media scope + +The first version supports banner inventory only. + +Non-banner formats are excluded before provider routing and are never emitted upstream. A slot with no valid banner format is skipped.

endpoints are fixed operator configuration, never client-derived. +- Clients cannot select provider IDs or endpoint URLs. +- Each bidder has one server-controlled provider route. +- Endpoint validation must preserve existing HTTPS and backend security requirements. +- Static extensions cannot contain secrets or request templates. +- Profiles cannot bypass central privacy enforcement. +- Profiles cannot access raw browser requests or unrestricted runtime services. +- Provider parameters must not be logged or returned in unbounded diagnostics. +- Existing response-body limits remain enforced. +- Existing creative sanitization remains enforced after winner selection. + +## Acceptance Criteria + +### Configuration and compilation + +- [ ] Provider instances are configured under `[auction.providers.*]`. +- [ ] The first version recognizes only `openrtb-2.6`. +- [ ] `standard`, `prebid-server`, and `aps` profiles are registered through Rust profile factories. +- [ ] Profile availability is independent of browser integration enablement. +- [ ] Provider and profile configuration is compiled once at startup. +- [ ] Deploy validation and runtime startup use the same provider compiler and registry. +- [ ] Duplicate provider IDs, unknown profiles, invalid endpoints, and invalid bidder routes fail validation. +- [ ] Target-specific validation rejects more than one active provider on adapters without concurrent fan-out support. +- [ ] Auction startup fails when required existing signing infrastructure is unavailable. + +### Routing + +- [ ] Clients submit bidder identities and parameters without selecting providers. +- [ ] `[auction.bidders]` routes each bidder to exactly one provider. +- [ ] Unknown runtime bidders are recorded as `unroutable_bidder` without failing other demand. +- [ ] `explicit` is the default provider routing mode. +- [ ] `all_eligible` is available only through explicit provider configuration. +- [ ] Trusted server-generated slots may route directly to providers without inline bidder parameters. +- [ ] Provider inputs contain only slots admitted by the provider's routing mode and only bidder parameters assigned to that provider. +- [ ] `all_eligible` does not expose bidder parameters assigned to another provider. +- [ ] Providers with no eligible slots are skipped without an upstream request. + +### OpenRTB and profiles + +- [ ] The common OpenRTB driver constructs current standard banner request fields. +- [ ] The common driver preserves existing consent, identity, floor, timeout, currency, and signing behavior. +- [ ] Tests prove that standard, Prebid Server, and APS requests apply the unchanged signing protocol after profile request augmentation. +- [ ] Standard OpenRTB endpoints can be configured without adding a provider implementation. +- [ ] Static `request.ext` and `imp.ext` objects are bounded and validated. +- [ ] Client bidder parameters are not assigned an invented generic wire location. +- [ ] The Prebid profile preserves current bidder parameters, stored requests, cache handling, diagnostics, and notification behavior. +- [ ] Prebid parity tests cover `openrtb_only`, `cookies_only`, and `both` using only the canonical allowlisted consent-cookie representation. +- [ ] The APS profile preserves current account extensions, inventory identity, response validation, renderer, script policy, and diagnostics. +- [ ] Prebid and APS no longer register singleton auction-provider instances. + +### Runtime behavior + +- [ ] At most one outbound request is sent per provider per auction, and none is sent when the provider has no eligible slots. +- [ ] Existing concurrent fan-out and timeout behavior remains intact. +- [ ] Provider failures remain isolated. +- [ ] Returned seats remain distinct from provider IDs. +- [ ] Existing winner selection, floors, mediation, creative delivery, and telemetry continue to behave as before. +- [ ] Banner behavior has parity with the existing Prebid and APS paths. +- [ ] Non-banner formats are excluded before routing and are never emitted upstream. +- [ ] A slot with no banner formats is skipped. +- [ ] Video and native are not introduced by this work. + +## Deferred Design Areas + +The following require separate requirements before implementation: + +- Additional protocols. +- Video and native support. +- Multiple provider routes for one bidder. +- Provider groups and label/rule-based routing. +- Request splitting for large auctions. +- New money or currency-conversion models. +- New signing protocol versions. +- New privacy or data-sharing controls. +- New diagnostics and telemetry schemas. +- General endpoint authentication configuration. +- Arbitrary standard-field mappings. +- Runtime or sandboxed profile extensions. + +## Open Questions + +No unresolved product decisions currently block this specification. + +Implementation planning must still identify: + +- The exact Rust profile-factory and compiled-profile interfaces. +- The minimal changes required to separate the current Prebid and APS logic into common OpenRTB and profile-owned behavior. +- The first concrete generic OpenRTB endpoint and whether it requires authentication or additional typed fields. +- The complete parity test fixture set for Prebid, APS, routing, signing, and split dispatch/collect execution. +- The exact configuration representation needed by existing environment override and app-config tooling. + +These are implementation-planning questions and must not expand the product scope defined above. + +## Related Designs

2026-08-11 +**Status:** Draft for implementation review +**Spec:** `docs/superpowers/specs/2026-08-10-config-first-auction-provider-architecture-design.md` +**Implementation baseline:** `main` at `af67d8c2`, including merged APS PR #918 + +## Baseline and branch requirement + +The design-spec branch predates the merged APS OpenRTB implementation. Implementation must start from current `main` at or after `af67d8c2`, not from the current documentation branch's Rust tree. Rebase or create a fresh implementation worktree after the specification is merged so the work preserves the current APS OpenRTB request, response, renderer, diagnostics, and parity tests. + +The implementation must not restore the pre-#918 APS `/e/dtb/bid` protocol or use the older encoded-price mediator-only path as its baseline. + +## Decisions locked for this plan + +- The generic `standard` compatibility endpoint is a fictional local mock available only under automated tests. It adds no runtime endpoint, profile, authentication option, or production-support claim. +- Provider ID, returned upstream seat, and browser-facing delivery bidder code are separate identities. + - Provider ID owns configuration, backend correlation, health, and telemetry. + - A valid string `seatbid.seat` is retained as `returned_seat`. + - Existing `Bid.bidder` remains the delivery bidder code for compatibility. + - PBS uses the returned seat or `unknown`; APS continues to use `aps`. +- Disabled global signing removes only signature-bearing fields. PBS retains its existing `request_host`/`request_scheme` object; APS and `standard` omit `ext.trusted_server`. +- Enabled global signing loads one auction-local signer before dispatch and applies the existing version 1.1 extension to every OpenRTB provider after profile augmentation. +- On an adapter with a future enforceable total-request deadline, late completions are timeouts and are discarded. No current adapter claims that capability; an already-launched completed response remains eligible, but no further provider or mediator network work starts after logical budget exhaustion. +- Existing mock mediation remains a statically registered, separately selected path. It is not represented by `ProviderPlan`, a profile, or a new generic mediator trait. +- `BTreeMap` or sorted vectors provide deterministic plan, route, request, and validation order. Runtime correctness must not depend on TOML or `HashMap` iteration order. +- Provider IDs use the spec's lowercase ASCII grammar and 63-byte limit. +- First-version bounds introduced by this work are constants with tests: + - at most 128 `notifications.suppress_seats` entries, each at most 128 UTF-8 bytes; + - at most 128 bidder entries in one `trustedServer.bidderParams` object; + - bidder IDs at most 128 UTF-8 bytes and `trustedServer.zone` at most 256 UTF-8 bytes; + - each static `request_ext` or `imp_ext` object at most 16 KiB serialized, at most eight object/array levels deep, and at most 256 keys at any one object level. +- The existing 256 KiB `/auction` body limit remains authoritative. Header snapshots use the exact first `HeaderMap` value already selected by the request layer and add no truncation behavior. +- No temporary old/new public configuration compatibility mode ships. Internal staging adapters may exist while the branch is under development, but they must be removed before the configuration schema switch is merged. + +## Definition of done + +- `[auction.providers]` and `[auction.bidders]` are the only server-side bidder-provider inventory and routing source. +- `standard`, `prebid-server`, and `aps` are compiled through one Rust registry into an immutable `AuctionPlan`. +- Deploy validation and every adapter startup use the same target-independent compiler; target-aware paths also run the same adapter capability and backend-name validation. +- Runtime request handling uses normalized auction data, a transport-owned Prebid header snapshot, and filtered `ProviderAuctionInput` values. Profiles do not receive the raw HTTP request or unrestricted runtime services. +- A generic OpenRTB 2.6 driver owns standard fields, common response decoding, request finalization, signing, and common notification suppression. +- PBS and APS singleton bidder-provider registration is removed after parity fixtures pass. +- Multiple instances of one profile dispatch and correlate by provider ID. +- Empty trusted Prebid envelopes, explicit bidder routing, APS `all_eligible`, unknown bidders, no-slot skips, and mixed browser demand follow the specification. +- PBS and APS request, response, privacy, creative, timeout, debug, and diagnostics behavior matches `main`, except for the intentional all-provider signing expansion. +- Provider ID, returned seat, and delivery bidder code remain independent through ranking, mediation, delivery, and telemetry. +- Existing ranking, floors, USD assumptions, mock mediation, creative sanitization, APS rendering, Prebid Cache, and telemetry remain intact. +- Example configuration, operator docs, and browser-injected Prebid configuration use the new ownership model. +- All target-specific tests, JS tests, integration parity tests, formatting, and clippy gates pass. + +## Proposed architecture + +### Raw and compiled configuration + +Add raw serde types under `auction_config_types.rs` and compile them into types that cannot represent unresolved references: + +```rust +pub struct AuctionConfig { + pub enabled: bool, + pub timeout_ms: u32, + pub providers: BTreeMap, + pub bidders: BTreeMap, + pub mediator: Option, +} + +pub struct AuctionPlan { + providers: Vec, + bidder_routes: BTreeMap, + signing_enabled: bool, +} + +pub struct ProviderPlan { + id: ProviderId, + endpoint: CanonicalProviderEndpoint, + timeout_ms: u32, + routing: RoutingMode, + notifications: NotificationPolicy, + protocol: ProtocolPlan, + profile: CompiledOpenRtbProfile, +} +``` + +Use newtypes for `ProviderId` and `BidderId`. Sort compiled providers by provider ID and store bidder routes as validated provider indexes or IDs. `AuctionPlan` stores only the enabled signing policy; it never stores loaded keys. + +The first-version protocol representation is a closed `ProtocolPlan::OpenRtb26` enum. Do not introduce scripting, dynamic loading, or a generalized protocol trait before a second protocol exists. + +### Profile registry and dispatch + +Use a small compile-time registration table rather than runtime plugins: + +```rust +pub struct OpenRtbProfileRegistration { + id: &'static str, + default_timeout: ProfileTimeoutDefault, + compile: fn(&serde_json::Value) -> Result>, +} + +enum CompiledOpenRtbProfile { + Standard(StandardProfilePlan), + PrebidServer(PrebidProfilePlan), + Aps(ApsProfilePlan), +} +``` + +The enum supplies typed methods for field policy, request augmentation, request-local parse state, response interpretation, and renderer capabilities. This is intentionally simpler than boxed `Any` state or a public capability-composition system. Adding a repository-owned profile requires a registration entry and enum variant, which is acceptable for the first version. + +Keep PBS-specific compilation and behavior in `integrations/prebid.rs` initially and APS-specific behavior in `integrations/aps.rs`. Expose narrow `pub(crate)` registration/compile hooks to the auction module. Do not convert either large integration file into a directory tree solely for this refactor. + +### Generic provider execution + +Replace singleton bidder providers with one generic planned OpenRTB provider execution path. It owns endpoint selection, backend specification, one-request-per-provider dispatch, common driver invocation, and response association. It dispatches profile behavior through `CompiledOpenRtbProfile` without matching profile names in the orchestrator. + +Adapt the existing `AuctionProvider` dispatch/parse seam rather than replacing the split dispatch/collect mechanism wholesale: + +- change static provider-name APIs to borrow the validated dynamic provider ID; +- let the generic planned provider carry one `Arc`; +- route and filter slots before invoking it; +- retain request-local profile parse state in the existing pending response token; +- split bidder-provider storage from the statically selected mock mediator so the mediator never enters the compiled plan. + +Delete PBS and APS singleton registration only after their planned profiles pass parity tests. + +### Admission and execution context + +Introduce an admitted request representation that separates canonical data from transport-only data: + +```rust +struct AdmittedAuction { + request: AuctionRequest, + prebid_headers: PrebidTransportHeaders, + signer: Option, +} + +struct ProviderAuctionInput { + provider_id: ProviderId, + slots: Vec, + canonical: Arc, + logical_budget_ms: u32, +} +``` + +The exact ownership can use references or `Arc` to avoid copying publisher/user/device data. Profiles receive `ProviderAuctionInput`, never the current raw-request-bearing `AuctionContext`. Common transport receives the private Prebid header snapshot. The existing mediator may continue receiving the broader legacy context until a separate mediation design changes it. + +Keep timeout values explicit and separate: + +- `logical_budget_ms = min(provider_timeout_ms, remaining_auction_ms)` controls launch and OpenRTB `tmax`. +- `transport_timeout_ms = backend.canonicalize_transport_timeout_ms(remaining_auction_ms, provider_timeout_ms)` controls backend identity and the adapter's available transport timers. + +Fastly quantization of `transport_timeout_ms` must never replace or shorten `logical_budget_ms`. + +### Bid identity + +Preserve `Bid.bidder` as the serialized delivery bidder code and add: + +```rust +pub returned_seat: Option +``` + +`AuctionResponse.provider` remains the provider ID. Update comments and constructors so these three identities cannot be accidentally interchanged. Keep `returned_seat` out of unchanged external mediator/client wire shapes where necessary and restore it from the original provider bid after mock mediation. Notification suppression matches only `returned_seat`; response serialization and the APS browser renderer continue to use `Bid.bidder`. The existing telemetry seat carrier uses `returned_seat` when present and falls back to `Bid.bidder` when absent. + +### Target validation + +Add a pure adapter validation description passed into the compiler's second stage: + +```rust +pub struct AuctionTargetCapabilities<'a> { + pub target_name: &'static str, + pub supports_concurrent_fanout: bool, + pub enforces_total_request_deadline: bool, + pub backend_name_predictor: &'a dyn PlatformBackend, +} +``` + +Reuse `PlatformBackend::predict_name` for startup validation. Where CLI validation cannot instantiate the runtime backend, extract one shared pure naming helper/descriptor and make both `predict_name` and CLI validation call it; do not create a second independently implemented codec. Cloudflare and Spin skip registration but still use their real deterministic names containing canonical backend-spec fields and the provider discriminator. + +Target-independent `ts config validate` runs stage one and emits an explicit message that adapter checks are deferred. Adapter startup always runs both stages. + +Target-aware `ts config push --adapter ` must validate before any remote read, prompt, or write. Add an EdgeZero typed-push callback API that receives the already deserialized, environment-overlaid `TrustedServerAppConfig` plus the selected adapter ID between EdgeZero's ordinary typed validation and its first remote operation. Trusted Server maps that ID to the same target capability/name-prediction descriptor used at startup and runs stage two in the callback. Pin the EdgeZero revision containing this hook. This keeps config loading, overlays, platform writes, and adapter selection inside EdgeZero while making target validation mandatory rather than duplicating a loader in Trusted Server. + +## Stage 1 — Pin behavioral parity before refactoring + +Files: + +- `crates/trusted-server-core/src/integrations/prebid.rs` +- `crates/trusted-server-core/src/integrations/aps.rs` +- `crates/trusted-server-core/src/auction/orchestrator.rs` +- `crates/trusted-server-core/src/auction/formats.rs` +- `crates/trusted-server-js/lib/test/integrations/prebid/index.test.ts` + +Steps: + +1.

Keep `[auction].mediator` validation separate and restricted to the existing static mock mediator. +6. Add compiler tests for every rejection, defaults, two same-profile instances, and browser integration independence. + +This stage is internal scaffolding only: do not replace `AuctionConfig.providers`, change `Settings`, or wire `validate_settings_for_deploy`. Compiler tests construct raw provider maps directly.

Reject more than one active provider for Cloudflare and Spin at target validation. Do not infer that only one will be requested at runtime. +7. Keep existing runtime collision assertions as defense in depth. +8. Add the EdgeZero typed-push validation callback, update the dependency pin, and test that the callback runs after overlays/typed validation but before any remote read or write. +9. Add unit tests that map each CLI adapter ID to the same capability/prediction descriptor used by startup and validate directly constructed plans. End-to-end map-shaped config-push rejection waits for the public schema cutover in Stage 11. +10. Add target prediction/capability tests and same-profile/same-endpoint independent-correlation tests.

Split canonical slot demand into bidder parameters, trusted provider routes, and bounded Prebid `zone` facts. +2. Normalize the reserved `trustedServer` envelope before central routing: + - missing/null/empty `bidderParams` produces stored-request intent; + - non-object, bad key/value, partial malformed, and bound violations reject admission and never fan out stored requests; + - valid unknown bidders route to `unroutable_bidder` and do not trigger fallback; + - usable direct objects win collisions, while unusable direct values cannot overwrite usable envelope objects; + - deterministic merge order is independent of map iteration. +3. Snapshot the first accepted `Cookie`, `User-Agent`, `Referer`, and `Accept-Language` values into a private `PrebidTransportHeaders`. Ignore client-supplied XFF and preserve the platform-attested IP separately. +4. Build one `ProviderAuctionInput` per provider: + - remove non-banner formats before routing; + - `explicit` receives only centrally routed or trusted slots; + - `all_eligible` receives every banner-compatible slot; + - parameters assigned to another provider are never copied; + - no valid banner formats means no provider input; + - no eligible slots produces a skip result without dispatch. +5. Convert creative-opportunity construction: + - explicit bidder parameters remain bidder IDs and use the central registry; + - empty Prebid stored-request intent expands to every compiled PBS plan; + - remove hard-coded APS provider selection and rely on `all_eligible` or explicit central/trusted routing. +6. Use the same admission/router helper for `/auction`, initial navigation, refresh/page-bids, and other server-generated auction entry points. +7. Add table-driven tests for routing, mixed providers, unknown bidders, empty/malformed envelopes, collisions, bounds, non-banner slots, and no parameter leakage. + +Verification: + +```bash +cargo test-fastly +cargo test-axum +``` + +## Stage 5 — Build the common OpenRTB driver and test-only standard profile + +Files: + +- new `crates/trusted-server-core/src/auction/openrtb.rs` +- `crates/trusted-server-core/src/openrtb.rs` +- `crates/trusted-server-core/src/auction/profile.rs` +- `crates/trusted-server-core/src/request_signing/signing.rs` +- `crates/trusted-server-core/src/auction/types.rs` + +Steps: + +1.

Implement fixed standard/PBS/APS field policies. Treat Stage 1 golden fixtures as normative, especially for consent and privacy differences. +3. Implement `StandardProfilePlan` with bounded static `request.ext` and `imp.ext`. It does not invent a wire location for bidder params. +4. Build response decoding around independent bid validation and preserve current profile-specific whole-response versus sibling-bid behavior. +5. Treat response `id` as informational for PBS/APS parity; keep transport association as the correlation boundary. +6. Add `Bid.returned_seat` while retaining `Bid.bidder` as delivery code. +7. Move signing to common finalization: + - profiles finish augmentation first; + - finalization freezes request ID and signing-owned fields; + - enabled signing inserts the existing v1.1 extension; + - disabled PBS can retain host/scheme only; + - disabled APS/standard omit the object. +8. Add exact serialized signing-on and signing-off fixtures for all three profiles. Assert each signature-bearing key separately: disabled PBS retains only host/scheme, disabled APS/standard omit the object, and every enabled request contains the full v1.1 extension after augmentation. +9. Add a `#[cfg(test)]` fictional standard endpoint mock using the existing stub HTTP-client machinery. Test ordinary bid, no-bid/204, malformed response isolation, static extensions, signed request compatibility, and no-auth behavior. No fixture handler or endpoint is compiled into production. +10. Add a common-transport redirect fixture: return 3xx with `Location`, assert no second request occurs, classify the original provider outcome, and prove the canonical endpoint used for request dispatch is the same one used for backend prediction/construction. + +Verification: + +```bash +cargo test-fastly +cargo test-axum +``` + +## Stage 6 — Build plan-backed orchestrator execution under test construction + +Files: + +- `crates/trusted-server-core/src/auction/provider.rs` +- `crates/trusted-server-core/src/auction/orchestrator.rs` +- `crates/trusted-server-core/src/auction/mod.rs` +- `crates/trusted-server-core/src/auction/endpoints.rs` + +Steps: + +1. Change static provider identity APIs to dynamic validated provider IDs. +2. Add one generic planned OpenRTB provider that combines a `ProviderPlan`, common driver, profile enum, and existing platform transport. +3. Add an internal/test constructor through which the orchestrator owns immutable plan-backed bidder providers and routes filtered inputs before launch. Production startup remains on the legacy constructor until Stage 11. +4. Preserve the existing split request/parse token and carry typed profile-local parse state without exposing another provider's state. +5. Prepare split mock mediator registration/lookup from bidder-provider storage. Keep its invocation and fallback unchanged, and restore `returned_seat` from the selected original provider bid rather than deriving it from mediator output. +6. Compute exact `logical_budget_ms` once for launch and `tmax`, then separately compute adapter-canonicalized `transport_timeout_ms` for backend naming/timers. Add Fastly tests proving timeout quantization never changes `tmax`. +7. Load the current signer once during common admission before routing/dispatch. A load failure returns before any `send_async` call. Do not cache signer keys at startup. +8. Ensure one request per eligible provider, no request for skipped providers, and no zero-impression request. +9. Keep provider failures isolated and preserve current local ranking/floor logic after normalization. +10. Add multi-instance tests for two providers with the same profile, endpoint, and timeout, proving independent backend correlation and outcome metadata. + +Stages 2 through 10 use internal construction scaffolding and tests without changing the public configuration/runtime path.

Define typed `PrebidProfileConfig` for debug, test mode, debug query params, override fields/rules, and consent forwarding. Prepare server endpoint, timeout, bidders, and notification suppression for common ownership, but keep the live legacy config fields until Stage 11. +2. Compile the current override engine once into `PrebidProfilePlan`. +3. Move PBS-only request behavior behind the profile: + - `imp.ext.prebid.bidder` from routed params; + - stored-request fallback for trusted routes; + - zone and generic override merge behavior; + - test/debug request fields and page query behavior; + - PBS-specific consent and Google Additional Consent policy; + - disabled-signing host/scheme extension fields. +4. Keep raw HTTP values out of the profile. Common Prebid transport applies the snapshot matrix for Cookie, UA, Referer, Accept-Language, and attested XFF. +5. Move PBS-only response behavior behind the profile: + - Prebid Cache coordinates; + - existing bid-status/debug metadata; + - request-local parse facts; + - current valid-sibling behavior and delivery bidder fallback. +6. Apply common notification suppression after PBS normalization and before ranking/mediation. +7. Exercise the profile through the internal planned-provider constructor while the live singleton remains unchanged. +8.

Define typed `ApsProfileConfig` for account ID, debug, script opt-in, and inventory identity overrides. Prepare endpoint and timeout for common provider ownership, but keep the live legacy config fields until Stage 11. +2. Express current APS request differences as its fixed field policy and owned account/SDK extensions. +3. Preserve current response validation, exact minimized renderer envelope, script gate, creative URL policy, diagnostics, and deterministic candidate reduction. +4. Capture a valid string `seatbid.seat` as `returned_seat`; use no returned seat for missing/non-string values. Keep `Bid.bidder = "aps"` so the existing renderer path remains active. +5. Preserve current APS removal/non-exposure of notification URLs before common configurable suppression. +6. Add a narrow validated-plan query for APS renderer activation and test it through the internal constructor; production registry wiring switches in Stage 11. +7. Make `all_eligible` the parity migration configuration and test optional `explicit` routing separately. +8. Exercise the profile through the internal planned-provider constructor while the live singleton remains unchanged. +9.

Define the post-cutover browser-only `[integrations.prebid]` shape, retaining `timeout_ms` and `debug` with 1000 ms/false defaults. +2. Prepare removal of server endpoint, server bidder allowlist, server debug, overrides, consent-forwarding, and suppression ownership, but do not change the live serde shape before Stage 11. +3. Keep browser bundle, account injection, script patterns, client-side bidders, and excluded GAM suffixes under `[integrations.prebid]`. +4. Add an injection path that consumes validated server-side bidder codes from `AuctionPlan`, not a second Prebid allowlist. Provider timeout/profile debug must never affect `pbjs.setConfig`; production startup passes the plan in Stage 11. +5. Preserve the current requestBids shim's initial and refresh snapshots, folding only server-side entries into `trustedServer.bidderParams` while leaving configured client-side bidders in the browser. +6. Add JS tests for: + - browser timeout/debug independence with multiple PBS plans; + - browser integration disabled while PBS profile compilation remains valid; + - mixed client-side, PBS, APS, and standard-provider demand; + - initial and refresh parameter preservation; + - empty stored-request envelopes; + - alternate returned bidder codes and APS renderer alias. +7.

Carry only booleans/counts. Do not include parameter values or bidder-ID lists. +3. Apply `suppress_all` and exact `returned_seat` suppression after profile normalization and before ranking/mediation. +4. Verify that missing/non-string seats do not match suppression, PBS still serializes `unknown`, and APS still serializes `aps`. +5. Restore `returned_seat` from the original provider bid after mock mediation. Make the existing telemetry seat field prefer `returned_seat` and fall back to delivery bidder code; add direct and mediated APS tests proving provider ID, upstream seat, and `aps` remain distinct. +6. Implement capability-dependent late completion behavior: + - a future hard-total-deadline adapter would discard/classify timeout; + - every current adapter accepts an already-completed late response because none claims an enforceable total-request deadline; + - neither path launches new provider or mediator network work at zero remaining budget; + - local ranking/delivery still finishes; + - synchronous and split dispatch/collect agree. +7. Preserve response times as actual elapsed times and document wall-clock overrun limitations in adapter docs/tests. +8. Run regression tests for no mediator, mock mediation, mediator timeout/fallback, floors, winner selection, creative sanitization, Prebid Cache, APS renderer delivery, and telemetry provider IDs/seats. +9.

Compile one `Arc` per process startup, run target validation once, and pass that same plan to both `AuctionOrchestrator` and `IntegrationRegistry`. Do not recompile or inspect unresolved provider config in either consumer. +3. Switch all four adapters to the generic plan-backed provider constructor and provider-ID backend discriminator. +4. Make `validate_settings_for_deploy` run the same target-independent compiler. Make target-aware `config push` run the EdgeZero pre-write callback with the selected adapter capabilities; keep `config validate` target-independent with an explicit deferred-check message. Add end-to-end tests proving Cloudflare/Spin multi-provider configs fail before any remote read, prompt, or write. +5. Remove PBS/APS singleton bidder-provider builders and their static backend discriminators. Retain the mock mediator in its separate static registration path. +6. Apply the prepared Prebid browser/server config split. Pass validated browser server-side bidder codes from the shared plan into integration injection. +7. Use `AuctionPlan::has_profile(ProfileId::Aps)` or an equivalent narrow query to register APS renderer support even when `[integrations.aps]` is disabled. Test renderer presence on every adapter. +8. Remove obsolete integration-owned server fields and update all serde, env-overlay, config-push, adapter, integration, and browser fixtures in the same cutover. +9. Replace examples/docs with `[auction.providers.*]`, `profile_config`, and `[auction.bidders.*]`; keep `[auction].mediator` separate. +10. Document browser/server Prebid ownership, APS `all_eligible`, provider ID and extension bounds, target validation, and current no-hard-total-deadline limitations.

On such an adapter, a completion after the enforced deadline is discarded and classified as a provider timeout. + +Fastly currently provides first-byte and between-byte backend timeout controls, not an absolute total-request deadline. Axum has broader task/client cancellation behavior, and Cloudflare and Spin may use eager or broader platform HTTP execution, but no current adapter claims an enforceable provider-wide total-request deadline for this capability. To preserve current behavior, an already-launched call may therefore complete after its logical budget and its completed response remains eligible for local ranking and delivery. No additional provider or mediator network work may launch once the auction has no remaining logical budget, but local decision and delivery still complete. This rule applies equally when split dispatch/collect observes a completed response after the logical deadline. Documentation and tests must state that such an auction can exceed the configured wall-clock budget. + +The plan compiler and target-specific validator use an adapter capability description that distinguishes: + +- Concurrent fan-out support. +- Enforceable total-request transport deadlines. + +Adapters without concurrent fan-out continue to reject configurations with more than one active bidder provider.

Legacy +provider constructors and manual registration are retained only for parity tests. ## Performance Considerations - **Parallel Execution**: Providers are launched concurrently via `select()` over `PendingRequest`s;

Three identity and consent paths treated a single stale read as authoritative. Fastly's KV list API reads the primary data source unless `eventual_consistency()` is requested, and `EcKvStore::count_keys_with_prefix` already rides that path on every adapter. `KvIdentityGraph::key_exists_confirmed` wraps it as a consistency-safe existence check, used wherever absence has real consequences. Withdrawal tombstones: a preloaded `Missing` no longer short-circuits `tombstone_existing_from_snapshot`. It is re-read — on the publisher path the re-read is separated from the preload by the full origin round trip — and a second miss is escalated to the existence check. A proven-absent key stays a no-op so forged cookies still mint nothing; a key the store still lists is tombstoned unconditionally, because no CAS generation survives a missed read and a withdrawal must win; a failed check leaves the withdrawal unresolved rather than silently dropped. EID ingestion: `upsert_partner_ids_from_snapshot` carries the existence proof held by an incoming `Present` snapshot — an `Add`-confirmed create or an earlier authoritative read. A refresh that misses or fails skips the update and logs it instead of returning `Missing`/`Failed`, so a transient miss can no longer suppress the `ts-ec` cookie for a root that was written. Write failures still report `Failed`: those are operation failures, not ambiguous reads. Post-send pull sync: dispatch was authorized entirely by the request snapshot, so a CMP withdrawal completing after the page response was flushed could still send the raw `ec_id` to partners. The live row is now re-read immediately before the first partner request and anything short of a live, consenting entry cancels the dispatch. The read sits behind the snapshot eligibility filter, so a dispatch with nothing to pull still costs no KV operation, and the fresh snapshot feeds the write-back instead of the stale one. Orphan recovery: rotation abandons a year-lived identity graph, so a second point-read miss is no longer enough. It now requires proven absence; a key the store still lists, or an existence check that fails, leaves the identity intact and retries recovery on a later navigation. --- crates/trusted-server-core/src/ec/finalize.rs | 122 ++++- crates/trusted-server-core/src/ec/kv.rs | 421 +++++++++++++++--- .../trusted-server-core/src/ec/kv_backend.rs | 120 +++++ .../trusted-server-core/src/ec/pull_sync.rs | 159 ++++++- 4 files changed, 736 insertions(+), 86 deletions(-) diff --git a/crates/trusted-server-core/src/ec/finalize.rs b/crates/trusted-server-core/src/ec/finalize.rs index d2e5636fc..e5e12f4c9 100644 --- a/crates/trusted-server-core/src/ec/finalize.rs +++ b/crates/trusted-server-core/src/ec/finalize.rs @@ -203,19 +203,24 @@ fn recover_orphaned_ec( }); } -/// Confirms an orphaned cookie is genuinely absent before rotating it. +/// Proves an orphaned cookie is genuinely absent before rotating it. /// -/// The origin-overlapped preload reads the identity-graph row while the -/// publisher origin is still in flight.

The Fastly adapter passed an unchanged `EcContext` into response finalization, which therefore saw `NotRead` and paid for a second billable lookup whenever `ts-eids` or `sharedId` carried an update — working against this PR's read-reduction goal. Both handlers now take `&mut EcContext` and store the loaded snapshot before returning, so finalization ingests EID updates from the read the endpoint already performed. `ec_id` and the consent context are taken by value in both handlers so the store-back does not conflict with a live borrow. The other adapters own their `EcContext` locally and only needed the binding made mutable.

The removed `[auction].providers = [...]` list and removed server fields under `[integrations.prebid]` and `[integrations.aps]` are rejected even when those integrations are disabled, and `ts config push` rejects the old shape before publication. Move PBS `server_url` to provider `endpoint`, server timeout to provider `timeout_ms`, request controls and bidder-parameter overrides to the `prebid-server` `profile_config`, notification suppression to `notifications`, and each former server bidder to an `[auction.bidders.]` route. Move APS endpoint, timeout, account, inventory, debug, and creative controls to an `aps` provider and its `profile_config`. Browser Prebid settings remain under `[integrations.prebid]`; values such as timeout and debug that previously affected both browser and server behavior must now be configured for each owner. Provider endpoints must be absolute HTTPS URLs. Only bidder codes present in `[auction.bidders]` are folded into Trusted Server requests; unlisted publisher bids remain native browser demand. This schema has no mixed-version-safe deployment order: old binaries reject the maps and new binaries reject the retired fields, so activate the new binary and config blob together. Rollbacks must restore an old-schema blob together with the old binary. - **Breaking** — Admin Basic-auth coverage now includes `GET /_ts/admin/ec`, `GET /_ts/admin/ec/{id}`, and `GET /_ts/admin/eids`. Existing configurations whose `[[handlers]]` patterns protect only the key-management endpoints now fail startup; broaden coverage before deploying, preferably with a namespace-boundary pattern such as `^/_ts/admin(?:/|$)`. Coverage of the dynamic `/_ts/admin/ec/{id}` route is no longer inferred from ID-shaped samples: the router accepts any segment after `/_ts/admin/ec/` and Basic Auth runs on the raw path before routing, so patterns anchored to the EC ID grammar (for example `^/_ts/admin/ec/[a-f0-9]{64}[.][A-Za-z0-9]{6}$`) are rejected in favor of a prefix-level matcher. Placeholder and well-known weak handler passwords (`changeme`, `password`, `admin`, `replace-with-…`) now fail startup on every handler rather than only on handlers inferred to cover an admin endpoint, because first-match-wins handler selection lets a narrow handler shadow the admin namespace. - Publisher HTML uses the browser-only `Cache-Control: private, max-age=60` policy for successful GET document responses and their `304 Not Modified` revalidations when server-side ad templates are structurally inactive, while preserving origin `private`/`no-store` policies and request-scoped bot, prefetch, or consent-denied responses. The `private` directive prevents shared caches that use `Cache-Control` from storing the document. Cookie-bearing responses using the generated inactive policy are finalized as `private, max-age=0`; CDN-specific cache headers remain unchanged and continue to control supporting CDNs independently. Set `[creative_opportunities].enabled = false` to disable publisher HTML and SPA template delivery without disabling direct `POST /auction` callers; an absent configuration, an unmatched slot, or a disabled auction also make the stack structurally inactive. An explicit `enabled = false` is not compatible with older binaries: restore the default, re-push and finalize the config before rolling back. - **Breaking** — Replaced the legacy APS contextual integration with APS OpenRTB at `/e/pb/bid`. APS configuration now uses canonical `account_id` (`pub_id` remains a compatibility alias), no longer requires APS-specific slot IDs, and defaults script creative eligibility off. Operators must update the endpoint, disable native APS demand for Trusted Server cohorts, and prepare GAM/Universal Creative targeting for `hb_bidder=aps` before rollout. `aps` entries in Prebid bidder lists are logged and stripped. APS renderer winners now preserve the upstream bid `id`, omit `crid` when APS omits it, and carry `ext.trusted_server.renderer` instead of `adm`; external `/auction` consumers must support this response shape. diff --git a/crates/trusted-server-core/src/auction/openrtb.rs b/crates/trusted-server-core/src/auction/openrtb.rs index 4d99ac24d..d9f20c42e 100644 --- a/crates/trusted-server-core/src/auction/openrtb.rs +++ b/crates/trusted-server-core/src/auction/openrtb.rs @@ -277,6 +277,11 @@ fn apply_prebid( _routed: &RoutedAuction, plan: &PrebidProfilePlan, ) -> Result<(), Report> { + debug_assert_eq!( + request.imp.len(), + input.slots().len(), + "should keep one impression per routed slot" + );

Preserve PR 1079's first-claimant policy: Trusted Server may +win an untouched physical slot, but must neither overwrite a publisher impression +nor let a stale response affect a later navigation. + +## Ownership model + +First-impression state remains keyed by navigation generation and exact physical +element identity. Each publisher auction gets an independent token whose +suppression decision is fixed when the auction is registered. When Trusted Server +commits its request, registration closes for new losing publisher auctions, while +already-registered losing tokens remain suppressible. Those tokens remain as +tombstones for the lifetime of the same navigation and exact physical element. +Unresolved suppressing tombstones are never evicted or removed by timeout or +auction failure; only navigation change or physical element replacement removes +them. The existing per-slot registration limit bounds the set before registration +closes, so an arbitrarily late correlated callback cannot become unrelated. + +Prebid's pending bid/code correlation records carry the navigation generation and +physical element identity captured at registration. A record is usable only while +both still match. Scoped `requestBids({ adUnitCodes })` calls inspect, mutate, +claim, and correlate only those requested global ad units. + +## Refresh suppression + +The Prebid delivery wrapper is the owner of first-impression delivery suppression. +When it suppresses a GPT slot, it also consumes any equivalent late-handoff +one-shot flag so the inner GPT wrapper cannot suppress the next legitimate +refresh. When it delegates a permitted GPT request, it consumes that flag at the +delegation boundary so the inner wrapper cannot silently drop the request. Mixed +refresh calls always forward the already-filtered slot list, including the path +where every remaining slot is excluded from a Prebid auction. That all-excluded +path performs the same ownership registration and consumption synchronously +before delegating. A bare refresh delayed by an auction becomes an explicit list +at callback time, preventing slots added after the snapshot from joining it. + +A publisher-triggered GPT refresh that starts a synthetic Prebid auction registers +its own per-slot first-impression tokens before waiting for the asynchronous +callback. A publisher-first token reserves the slot so TS cannot claim it while +the auction is pending. A token registered against an earlier TS claim is consumed +at callback time, filtering that slot from the eventual GPT request. When TS emits +its first GPT request, registration closes for new losing publisher tokens so +ordinary later publisher refreshes continue normally. Mixed callbacks forward +only their unsuppressed slots and scope Prebid targeting to the same filtered set. +The callback also revalidates the captured navigation generation and exact +physical element, dropping stale work rather than refreshing a replacement slot. + +## Creative bridge + +Every asynchronous renderer/cache result is revalidated before posting a creative +response or recording successful response/billing evidence. A stale result may be +recorded as safe failure telemetry, but is never recorded as a response or win. +Validation covers navigation +generation, winning bid identity, authenticated source iframe identity, DOM +connectivity, and containment in the authenticated slot root. + +After a valid response is posted, a collapsed 1x1 source iframe is expanded to the +winning creative size. The bridge walks all collapsed ancestors through the +authenticated slot root and expands each clipping shell. It refuses all resizing +for fixed/sticky, anchor, vignette, interstitial, detached, oversized, or +otherwise unauthenticated shells. + +## Verification + +Regression tests cover all seven review findings, including wrapper composition, +scoped ad-unit requests, mixed excluded refreshes, stale SPA callbacks, +overlapping auctions, stale cache responses with no successful response/billing +evidence, and two nested +collapsed ancestors.

The removed `[auction].providers = [...]` list and removed server fields under `[integrations.prebid]` and `[integrations.aps]` are rejected even when those integrations are disabled, and `ts config push` rejects the old shape before publication. Move PBS `server_url` to provider `endpoint`, server timeout to provider `timeout_ms`, request controls and bidder-parameter overrides to the `prebid-server` `profile_config`, notification suppression to `notifications`, and each former server bidder to an `[auction.bidders.]` route. Move APS endpoint, timeout, account, inventory, debug, and creative controls to an `aps` provider and its `profile_config`. Browser Prebid settings remain under `[integrations.prebid]`; values such as timeout and debug that previously affected both browser and server behavior must now be configured for each owner. Provider endpoints must be absolute HTTPS URLs. Only bidder codes present in `[auction.bidders]` are folded into Trusted Server requests; unlisted publisher bids remain native browser demand. This schema has no mixed-version-safe deployment order: old binaries reject the maps and new binaries reject the retired fields, so activate the new binary and config blob together. Rollbacks must restore an old-schema blob together with the old binary. - **Breaking** — Admin Basic-auth coverage now includes `GET /_ts/admin/ec`, `GET /_ts/admin/ec/{id}`, and `GET /_ts/admin/eids`. Existing configurations whose `[[handlers]]` patterns protect only the key-management endpoints now fail startup; broaden coverage before deploying, preferably with a namespace-boundary pattern such as `^/_ts/admin(?:/|$)`. Coverage of the dynamic `/_ts/admin/ec/{id}` route is no longer inferred from ID-shaped samples: the router accepts any segment after `/_ts/admin/ec/` and Basic Auth runs on the raw path before routing, so patterns anchored to the EC ID grammar (for example `^/_ts/admin/ec/[a-f0-9]{64}[.][A-Za-z0-9]{6}$`) are rejected in favor of a prefix-level matcher. Placeholder and well-known weak handler passwords (`changeme`, `password`, `admin`, `replace-with-…`) now fail startup on every handler rather than only on handlers inferred to cover an admin endpoint, because first-match-wins handler selection lets a narrow handler shadow the admin namespace. +- Prebid Server provider endpoints now normalize origin-only legacy `server_url` values to `/openrtb2/auction`. Query parameters are preserved, the canonical path loses a trailing slash, and configured non-root custom paths remain exact. - Publisher HTML uses the browser-only `Cache-Control: private, max-age=60` policy for successful GET document responses and their `304 Not Modified` revalidations when server-side ad templates are structurally inactive, while preserving origin `private`/`no-store` policies and request-scoped bot, prefetch, or consent-denied responses. The `private` directive prevents shared caches that use `Cache-Control` from storing the document. Cookie-bearing responses using the generated inactive policy are finalized as `private, max-age=0`; CDN-specific cache headers remain unchanged and continue to control supporting CDNs independently. Set `[creative_opportunities].enabled = false` to disable publisher HTML and SPA template delivery without disabling direct `POST /auction` callers; an absent configuration, an unmatched slot, or a disabled auction also make the stack structurally inactive. An explicit `enabled = false` is not compatible with older binaries: restore the default, re-push and finalize the config before rolling back. - **Breaking** — Replaced the legacy APS contextual integration with APS OpenRTB at `/e/pb/bid`. APS configuration now uses canonical `account_id` (`pub_id` remains a compatibility alias), no longer requires APS-specific slot IDs, and defaults script creative eligibility off. Operators must update the endpoint, disable native APS demand for Trusted Server cohorts, and prepare GAM/Universal Creative targeting for `hb_bidder=aps` before rollout. `aps` entries in Prebid bidder lists are logged and stripped. APS renderer winners now preserve the upstream bid `id`, omit `crid` when APS omits it, and carry `ext.trusted_server.renderer` instead of `adm`; external `/auction` consumers must support this response shape. - **Breaking** — All auction paths now forward only a validated publisher-owned page URL as `site.page`, removing query and fragment data. APS OpenRTB omits `site.ref`; the existing Prebid Server path continues to forward the browser `Referer` as `site.ref`. Query-driven sites may lose contextual targeting and per-page reporting signals that previously came from query parameters. diff --git a/crates/trusted-server-core/src/auction/openrtb/tests.rs b/crates/trusted-server-core/src/auction/openrtb/tests.rs index c684b0cde..41c4e59d1 100644 --- a/crates/trusted-server-core/src/auction/openrtb/tests.rs +++ b/crates/trusted-server-core/src/auction/openrtb/tests.rs @@ -1,4 +1,4 @@ -use std::collections::{BTreeMap, BTreeSet, HashMap};

Honor Fastly logical-to-physical store mappings, preserve deserialize-only selector compatibility, redact runtime values, and document provisioning and migration behavior. --- .env.example | 2 +

Preserve PR 1079's first-claimant policy: Trusted Server may +win an untouched physical slot, but must neither overwrite a publisher impression +nor let a stale response affect a later navigation. + +## Ownership model + +First-impression state remains keyed by navigation generation and exact physical +element identity. Each publisher auction gets an independent token whose +suppression decision is fixed when the auction is registered. When Trusted Server +commits its request, registration closes for new losing publisher auctions, while +already-registered losing tokens remain suppressible. Those tokens remain as +tombstones for the lifetime of the same navigation and exact physical element. +Unresolved suppressing tombstones are never evicted or removed by timeout or +auction failure; only navigation change or physical element replacement removes +them. The existing per-slot registration limit bounds the set before registration +closes, so an arbitrarily late correlated callback cannot become unrelated. + +Prebid's pending bid/code correlation records carry the navigation generation and +physical element identity captured at registration. A record is usable only while +both still match. Scoped `requestBids({ adUnitCodes })` calls inspect, mutate, +claim, and correlate only those requested global ad units. + +## Refresh suppression + +The Prebid delivery wrapper is the owner of first-impression delivery suppression. +When it suppresses a GPT slot, it also consumes any equivalent late-handoff +one-shot flag so the inner GPT wrapper cannot suppress the next legitimate +refresh. When it delegates a permitted GPT request, it consumes that flag at the +delegation boundary so the inner wrapper cannot silently drop the request. Mixed +refresh calls always forward the already-filtered slot list, including the path +where every remaining slot is excluded from a Prebid auction. That all-excluded +path performs the same ownership registration and consumption synchronously +before delegating. A bare refresh delayed by an auction becomes an explicit list +at callback time, preventing slots added after the snapshot from joining it. + +A publisher-triggered GPT refresh that starts a synthetic Prebid auction registers +its own per-slot first-impression tokens before waiting for the asynchronous +callback. A publisher-first token reserves the slot so TS cannot claim it while +the auction is pending. A token registered against an earlier TS claim is consumed +at callback time, filtering that slot from the eventual GPT request. When TS emits +its first GPT request, registration closes for new losing publisher tokens so +ordinary later publisher refreshes continue normally. Mixed callbacks forward +only their unsuppressed slots and scope Prebid targeting to the same filtered set. +The callback also revalidates the captured navigation generation and exact +physical element, dropping stale work rather than refreshing a replacement slot. + +## Creative bridge + +Every asynchronous renderer/cache result is revalidated before posting a creative +response or recording successful response/billing evidence. A stale result may be +recorded as safe failure telemetry, but is never recorded as a response or win. +Validation covers navigation +generation, winning bid identity, authenticated source iframe identity, DOM +connectivity, and containment in the authenticated slot root. + +After a valid response is posted, a collapsed 1x1 source iframe is expanded to the +winning creative size. The bridge walks all collapsed ancestors through the +authenticated slot root and expands each clipping shell. It refuses all resizing +for fixed/sticky, anchor, vignette, interstitial, detached, oversized, or +otherwise unauthenticated shells. + +## Verification + +Regression tests cover all seven review findings, including wrapper composition, +scoped ad-unit requests, mixed excluded refreshes, stale SPA callbacks, +overlapping auctions, stale cache responses with no successful response/billing +evidence, and two nested +collapsed ancestors. Existing JS unit/browser suites, formatting, lint, build, +and repository Rust verification remain the completion gates.

Revalidate a matching `Missing` once before the updates are dropped; a refresh that still misses keeps the no-create behavior, and an already-failed lookup is still not retried on the hot path. Withdrawal tombstones that exhausted every CAS attempt returned `EcKvSnapshot::Failed` with no log, and finalization discarded the outcome entirely for a non-active cookie ID. The browser cookie is cleared while the KV row can stay live with consent granted, so operators had no signal that withdrawal enforcement failed. Log CAS exhaustion for both the tombstone and the snapshot partner upsert, and warn on every failed withdrawal outcome in finalization. --- crates/trusted-server-core/src/ec/finalize.rs | 100 +++++++++++- crates/trusted-server-core/src/ec/kv.rs | 148 +++++++++++++++++- 2 files changed, 239 insertions(+), 9 deletions(-) diff --git a/crates/trusted-server-core/src/ec/finalize.rs b/crates/trusted-server-core/src/ec/finalize.rs index e5e12f4c9..e756bd447 100644 --- a/crates/trusted-server-core/src/ec/finalize.rs +++ b/crates/trusted-server-core/src/ec/finalize.rs @@ -18,7 +18,7 @@ use super::kv::{CreateIfAbsentOutcome, KvIdentityGraph, apply_partner_id_updates use super::kv_types::KvEntry; use super::prebid_eids::collect_eid_cookie_updates; use super::registry::PartnerRegistry; -use super::{EcKvSnapshot, current_timestamp}; +use super::{EcKvSnapshot, current_timestamp, log_id}; /// TS-managed response headers tied to EC identity output. const EC_RESPONSE_HEADERS: &[&str] = &[ @@ -76,6 +76,18 @@ pub fn ec_finalize_response( EcKvSnapshot::NotRead }; let outcome = graph.tombstone_existing_from_snapshot(ec_id, initial); + // The browser cookie is already cleared, so a failed + // tombstone leaves a live row that server-side consumers + // still read as consented.

Provider endpoints must be absolute HTTPS URLs. Only bidder codes present in `[auction.bidders]` are folded into Trusted Server requests; unlisted publisher bids remain native browser demand. Provider response names now use the configured provider ID, such as `pbs-main`, instead of the legacy literal `prebid`; audit consumers that match `AuctionResponse.provider`. This schema has no mixed-version-safe deployment order: old binaries reject the maps and new binaries reject the retired fields, so activate the new binary and config blob together. Rollbacks must restore an old-schema blob together with the old binary. - **Breaking** — Admin Basic-auth coverage now includes `GET /_ts/admin/ec`, `GET /_ts/admin/ec/{id}`, and `GET /_ts/admin/eids`. Existing configurations whose `[[handlers]]` patterns protect only the key-management endpoints now fail startup; broaden coverage before deploying, preferably with a namespace-boundary pattern such as `^/_ts/admin(?:/|$)`. Coverage of the dynamic `/_ts/admin/ec/{id}` route is no longer inferred from ID-shaped samples: the router accepts any segment after `/_ts/admin/ec/` and Basic Auth runs on the raw path before routing, so patterns anchored to the EC ID grammar (for example `^/_ts/admin/ec/[a-f0-9]{64}[.][A-Za-z0-9]{6}$`) are rejected in favor of a prefix-level matcher. Placeholder and well-known weak handler passwords (`changeme`, `password`, `admin`, `replace-with-…`) now fail startup on every handler rather than only on handlers inferred to cover an admin endpoint, because first-match-wins handler selection lets a narrow handler shadow the admin namespace. - Prebid Server provider endpoints now normalize origin-only legacy `server_url` values to `/openrtb2/auction`. Query parameters are preserved, the canonical path loses a trailing slash, and configured non-root custom paths remain exact. - Publisher HTML uses the browser-only `Cache-Control: private, max-age=60` policy for successful GET document responses and their `304 Not Modified` revalidations when server-side ad templates are structurally inactive, while preserving origin `private`/`no-store` policies and request-scoped bot, prefetch, or consent-denied responses. The `private` directive prevents shared caches that use `Cache-Control` from storing the document. Cookie-bearing responses using the generated inactive policy are finalized as `private, max-age=0`; CDN-specific cache headers remain unchanged and continue to control supporting CDNs independently. Set `[creative_opportunities].enabled = false` to disable publisher HTML and SPA template delivery without disabling direct `POST /auction` callers; an absent configuration, an unmatched slot, or a disabled auction also make the stack structurally inactive. An explicit `enabled = false` is not compatible with older binaries: restore the default, re-push and finalize the config before rolling back. diff --git a/TESTING.md b/TESTING.md index a68f33222..c50d10a67 100644 --- a/TESTING.md +++ b/TESTING.md @@ -1,62 +1,20 @@ -# Testing the Auction Orchestration System +# Testing auction orchestration -## Quick Test Summary +## Start the local server -The auction orchestration system has been integrated into the existing Prebid endpoints.

Main Router (main.rs) -The Fastly Compute entrypoint uses pattern matching on `(Method, path)` tuples: - -```rust -let result = match (method, path.as_str()) { - // Auction endpoint - (Method::POST, "/auction") => { - handle_auction(&settings, &orchestrator, &runtime_services, req).await - }, - - // First-party endpoints - (Method::GET, "/first-party/proxy") => handle_first_party_proxy(&settings, req).await, - - // Integration registry (dynamic routes) - (m, path) if integration_registry.has_route(&m, path) => { - integration_registry.handle_proxy(&m, path, &settings, req).await - }, - - // Fallback to publisher origin - _ => handle_publisher_request(&settings, &integration_registry, &runtime_services, req), -} -``` +A plan-backed orchestrator contains generic OpenRTB providers compiled from the +plan. `AuctionOrchestrator::register_provider` and the old concrete Prebid +provider remain test-only parity code. They are not extension APIs. -#### 2. Integration Registry (Dynamic Routes) -Some integrations register their own routes dynamically. For example, Prebid registers `/integrations/prebid/auction`: - -```rust -// In integrations/prebid.rs -impl Integration for PrebidIntegration { - fn routes(&self) -> Vec { - vec![ - IntegrationRoute { - path: "/integrations/prebid/auction", - method: Method::POST, - handler: handle_prebid_auction, - } - ] - } -} -``` +## Routing -The integration registry checks if a route matches any registered integration routes before falling back to the publisher origin. - -#### 3. Route Priority -Routes are matched in this order: -1. **Exact top-level routes** (`/auction`, `/first-party/proxy`, etc.) -2. **Admin routes** (`/_ts/admin/*`) -3. **Integration routes** (`/integrations/*`) -4. **Fallback to publisher origin** (all other paths) - -This ensures auction and first-party endpoints take precedence over publisher content. - -### Auction Endpoint Deep Dive - -The `/auction` endpoint is the primary entry point for auctions: - -**Input Format (Prebid.js compatible):** -```json -{ - "adUnits": [ - { - "code": "div-id", - "mediaTypes": { - "banner": { - "sizes": [[300, 250], [728, 90]] - } - } - } - ], - "config": { /* optional Prebid.js config */ } -} -``` +`routing::route_auction` normalizes the browser `trustedServer` envelope and +produces one `ProviderAuctionInput` per provider. -**Output Format (OpenRTB 2.x):** -```json -{ - "id": "auction-response", - "seatbid": [ - { - "seat": "bidder-name", - "bid": [ - { - "id": "bid-id", - "impid": "div-id", - "price": 2.5, - "adm": "", - "w": 300, - "h": 250 - } - ] - } - ], - "ext": { - "orchestrator": { - "strategy": "parallel_only", - "bidders": 2, - "total_bids": 3, - "time_ms": 150 - } - } -} -``` +- `explicit` sends a slot only when it has bidder demand assigned to that + provider, or trusted stored-request demand where the profile supports it. +- `all_eligible` sends every compatible banner slot without copying another + provider's bidder params. +- `prebid-server` requires `explicit`.
