Retire `SendBuffer` and every force path. This is the phase that makes the whole feature correct. + +#### Deliverables +- [ ] `handleSend` rewrite in `packages/codev/src/agent-farm/servers/tower-routes.ts`: persist the row (before + the response), then attempt delivery through the gate; return `delivered` or `held`+id+reason. +- [ ] Per-session **write serialization** (FIFO, completion-chained) — `packages/codev/src/agent-farm/servers/message-write.ts` + (extend) or a sibling `write-queue.ts`; a message's text and its Enter are one unit. +- [ ] Delivery driver + **poll backstop** replacing `SendBuffer`'s timer: `startSendBuffer`/`stopSendBuffer` + call sites in `tower-server.ts` (587 / 185) become the mailbox drainer's lifecycle; **delete** + `send-buffer.ts` and its test (behavior migrated). +- [ ] Delivery moments in this phase: **enqueue-time** check + **poll backstop** (a periodic held-row drain that + runs the gate). (Submit/quiescence triggers are Phase 5.) +- [ ] Additive response fields on `POST /api/send` (`held`, `mailboxId`, `reason`) preserving `ok`/`terminalId`/ + `deferred` for old binaries (`held` ⇒ still `ok:true`). +- [ ] Dead-session → held (`no-live-pty`), unknown-app → held (`no-profile`) — the WARN/ERROR drop paths removed. +- [ ] **Dead-session targeting seam** (so a message to an agent with no live PTY is *held*, not 404'd): today + `resolveTarget` (`packages/codev/src/agent-farm/servers/tower-messages.ts:152`) resolves only against live + `getWorkspaceTerminals()`, and `handleSend` 404s when no live PTY exists — so the `no-live-pty` hold isn't + reachable as-is. Add an agent-registry fallback (resolve a known agent from the global.db `builders`/ + `architect` registry via `state.ts` when no live terminal matches) and restructure `handleSend` so a + resolved-but-no-live-PTY target **persists a `no-live-pty` held row instead of 404ing**. +- [ ] **Client-side send contract** (so the sender sees the real outcome): extend the send return type in + `packages/core/src/tower-client.ts` (add `held`, `reason`, `mailboxId` alongside the existing `ok`/`resolvedTo`/`error`) + and change `packages/codev/src/agent-farm/commands/send.ts` to report the real outcome on **both** paths — + the single-send output (`:332`, today an unconditional "Message sent") **and the `--all` path** + (`sendToAll()` at `:200`, which today pushes to `sent` on any `ok`): report `delivered` vs + `held () — id ` per target, and aggregate held vs delivered counts for `--all`. +- [ ] **`pruneTerminal` invocation** wired here (defined in Phase 1): call it on Tower boot and once per backstop + drain so terminal rows don't accumulate. +- [ ] **Liveness-telemetry tracking** instrumented in the drainer (per-session repeated not-clean verdict counter); + the state lives with the gate loop here — Phase 7 surfaces it (loud log/broadcast). +- [ ] Tests: `packages/codev/src/agent-farm/__tests__/send-delivery.test.ts` (+ update send-buffer callers); + **automated e2e** for the #1265 repro at `packages/codev/src/agent-farm/__tests__/send-mailbox.e2e.test.ts` + (or extend the existing `send-integration.e2e.test.ts`), run via `vitest.e2e.config.ts`. + +#### Implementation Details +- **Persist-first**: enqueue the mailbox row before writing the HTTP response; the response reports the real + first outcome (an idle clean prompt delivers at enqueue-time → `delivered`; otherwise `held`+reason). +- **Gate before every automated write** (Baked Decision 3). The sole bypass is `--interrupt`, unchanged + (`session.write('\x03')` then write without a gate check). `escape` path unchanged. +- **Serialization**: writes to one live PTY chain on completion (reuse the paced-write completion time already + returned by `writeMessageToSession`). Held rows drain in `created_at` order per agent. +- **Retire force paths**: no `flush(true)` on shutdown; no max-age force. Shutdown just stops the drainer; + held rows persist in SQLite. +- **Respawn drain**: rows address the agent, so a new terminal for the same agent drains predecessor mail on + its first clean gate pass. +- `noEnter`: gate-checked staging (writes text, no Enter) → reports `delivered` (the write completed). + +#### Acceptance Criteria +- [ ] #1265 repro: draft in target, send → held (`busy`), draft untouched; after the line clears + backstop + poll, delivers cleanly. +- [ ] Idle empty prompt → immediate `delivered`, correct rendering. +- [ ] Menu/picker/trust-dialog/wrapper → held; delivers after clean. +- [ ] Tower restart with held rows → rows survive; delivery only after a clean gate pass. +- [ ] Respawned agent (new terminal id) drains predecessor's held mail. +- [ ] Concurrent sends → serialized, ordered, no blobbing (spike `w1a` scenario). +- [ ] Dead-session send → held (`no-live-pty`); unknown-app → held (`no-profile`). +- [ ] `--interrupt` bypasses holding; `noEnter` stages without submit and a follow-up holds behind it. +- [ ] Old-binary response shape intact (`ok`, `terminalId`, `deferred` still present). + +#### Test Plan +- **Unit**: gate-pass → write; gate-fail → held with reason; serialization ordering; response field shape. +- **Integration**: full `handleSend` against a fake session + gate (idle/draft/menu); restart recovery; + respawn drain; concurrent-send serialization. +- **E2E** (automated, `vitest.e2e.config.ts`): the #1265 repro — draft → send → held(`busy`) → submit → clean delivery. +- **Manual**: also reproduce #1265 by hand against a live builder terminal as a sanity check. + +#### Rollback Strategy +This phase changes live behavior. Rollback = revert the phase commit, which restores `SendBuffer` (kept in git +history) and the prior `handleSend`. Because Phases 1–3 are inert without this wiring, reverting Phase 4 alone +returns the system to today's behavior cleanly. + +#### Risks +- **Risk**: process swap in the gate→write gap (wrapper transition race). **Mitigation**: accepted residual + (spec Risks); a failed gate or errored write leaves the row held; only a completed write marks delivered. +- **Risk**: removing `SendBuffer` disturbs its callers/tests. **Mitigation**: grep all `sendBuffer`/`SendBuffer` + sites (tower-server.ts, tower-routes.ts, two tests) and migrate them in this phase; "who calls this?" sweep. + +--- + +### Phase 5: Fast delivery triggers (submit + quiescence) +**Dependencies**: Phase 4 + +#### Objectives +- Reduce held-message latency from "next backstop poll" to "near-immediate once the human clears the line," by + scheduling a gate-check + drain on user-submit and on output quiescence. + +#### Deliverables +- [ ] Submit trigger: on detecting a user submit for a session (Enter), schedule that session's held-row drain. +- [ ] Quiescence trigger: when a session's output goes quiet (using `lastDataAt`), schedule a drain. +- [ ] Wiring in `pty-session.ts` (emit/track the signals) + the mailbox drainer (consume them). No new gate + logic — triggers only *schedule* the existing gate check. +- [ ] Tests extending `send-delivery.test.ts`: held message delivers on submit/quiescence without waiting for + the backstop. + +#### Implementation Details +Triggers are cheap schedulers, never authority (spec Constraint). A missed trigger only delays delivery to the +next backstop poll — it can't corrupt anything, so the detection heuristics stay deliberately simple. Submit +detection reuses existing input tracking (`recordUserInput`/composing signals); quiescence reuses Spec 467's +`lastDataAt`. + +#### Acceptance Criteria +- [ ] After a draft is submitted, a previously-held message delivers on the submit trigger (before the backstop + would fire), on a now-clean prompt. +- [ ] A message held during agent output delivers shortly after output quiesces. +- [ ] A missed/spurious trigger never delivers onto a non-clean screen (gate still decides). + +#### Test Plan +- **Unit**: trigger → drain scheduled → gate decides; **drain coalescing** (a pending drain supersedes another → + the gate runs once, not once per trigger). **Integration**: submit-then-deliver; quiesce-then-deliver; + spurious trigger on a dirty screen → still held. + +#### Rollback Strategy +Revert the phase commit; delivery falls back to enqueue-time + backstop (Phase 4 latency), still correct. + +#### Risks +- **Risk**: trigger storms cause redundant gate checks. **Mitigation**: coalesce per session (a pending drain + supersedes another); gate cost is single-digit ms at realistic sizes. + +--- + +### Phase 6: Cron rerouting through mailbox + gate +**Dependencies**: Phase 4 + +#### Objectives +- Bring the most-unguarded writer onto the single gated path, with per-task supersede and honest run logs. + +#### Deliverables +- [ ] `deliverMessage` in `packages/codev/src/agent-farm/servers/tower-cron.ts` (303–323) routes through the + mailbox + gate instead of the blind `writeMessageToSession`. +- [ ] Per-task **supersede key** = task name (Baked Decision 6): a newer run replaces the older *held* row. +- [ ] Cron run log records the real outcome (`delivered` / `held` / `superseded`), not unconditional "delivered". +- [ ] Tests: `packages/codev/src/agent-farm/__tests__/cron-delivery.test.ts`. + +#### Implementation Details +Cron becomes an ordinary mailbox sender with a supersede key. Reuse Phase 4's enqueue + delivery entrypoint so +there is exactly one gated path. Non-cron sends never supply a supersede key (spec Decision 6 — cron-only). + +#### Acceptance Criteria +- [ ] Cron message onto a busy/menu screen → held (never blind-written). +- [ ] A newer run of the same task supersedes the older held row (no backlog). +- [ ] Run log shows the real outcome. + +#### Test Plan +- **Unit**: cron enqueue with supersede key; supersede replaces held. **Integration**: busy target → held; + second run supersedes; log assertions. + +#### Rollback Strategy +Revert the phase commit; cron returns to its prior direct write (regains its old bug, but isolated). + +#### Risks +- **Risk**: cron backlog if supersede key is wrong. **Mitigation**: key = task name (stable); test supersede + explicitly. + +--- + +### Phase 7: afx inbox CLI + broadcasts + escalation +**Dependencies**: Phase 1, Phase 4 + +#### Objectives +- Make held messages discoverable and actionable without reading Tower logs: `afx inbox` (list + dismiss), the + two broadcast events that keep indicators live, and the escalation-age visibility transition. + +#### Deliverables +- [ ] `packages/codev/src/agent-farm/commands/inbox.ts` — `afx inbox` (list all held rows workspace-wide: id, + reason, from→to, age) and `afx inbox dismiss `. +- [ ] Command registration in `packages/codev/src/agent-farm/cli.ts` (commander, mirroring `send`). +- [ ] Tower API: `GET /api/inbox` + `POST /api/inbox/:id/dismiss` in `tower-routes.ts`. +- [ ] **Held state surfaced through the existing overview/SSE channel** (not the inter-agent `broadcastMessage` + channel): add a workspace `heldCount` (and optional per-agent `heldCount`) to `OverviewData`/`OverviewBuilder` + in `packages/types/src/api.ts`, populated from the mailbox in + `packages/codev/src/agent-farm/servers/overview.ts`. Fire `overview-changed` + (`ctx.broadcastNotification`, precedent `tower-routes.ts:1307`) on every held-state change + (hold/deliver/supersede/dismiss) so both UIs refetch and the count stays live — this is the spec's + **held-state-change broadcast**. +- [ ] **Escalation event**: a distinct SSE `notification` event (per the `packages/types/src/sse.ts` contract) + plus an attention flag in the overview payload — the spec's **escalation broadcast**. +- [ ] Escalation-age handling in the mailbox drainer: a held row past the threshold (default 60s; configurable + via `.codev/config.json`, read through `packages/codev/src/lib/config.ts` — add the key to `CodevConfig` + + `DEFAULT_CONFIG`) → set `escalated`, emit the escalation `notification` + a loud log; **never** deliver. +- [ ] Liveness telemetry **surfacing**: the drainer's per-session not-clean verdict counter (instrumented in + Phase 4) crossing a threshold with recent output → loud log/broadcast (broken-profile discoverability, + spec Constraint). +- [ ] Tests: `…/__tests__/inbox.test.ts` + escalation-age test. + +#### Implementation Details +Dismiss is a soft transition (mark `dismissed`, not delete — auditable; pruned later by Phase 1's `pruneTerminal`). +Dismissal is workspace-human-authorized (any operator may dismiss any held row; no per-recipient check — +spec Decision 8). Bodies never appear in logs — ids + metadata only (spec Security). Because mailbox rows are +**agent-addressed** (`workspace_path` + `to_agent`), the overview's `heldCount` computes directly per agent/ +workspace — cleaner than the retired `SendBuffer`, which was PTY-`sessionId`-keyed and would have needed a +session→builder mapping to surface a per-builder count. + +#### Acceptance Criteria +- [ ] `afx inbox` lists every held row with its why-held reason immediately after it's held. +- [ ] `afx inbox dismiss ` marks it dismissed, drops it from the held set, and never delivers it. +- [ ] Crossing the escalation age emits the escalation broadcast + attention log; no delivery is triggered. +- [ ] Reasons (`busy`/`no-profile`/`no-live-pty`) are distinguishable in `afx inbox` and the send response. +- [ ] Message bodies never appear in Tower logs (assert on captured log output). + +#### Test Plan +- **Unit**: inbox list/dismiss; escalation threshold transition; body-redaction in logs. **Integration**: + held row → `afx inbox` shows it → dismiss → gone from list, not delivered. + +#### Rollback Strategy +Revert the phase commit; held rows still exist (Phase 1) and still drain (Phase 4) — only the visibility surface +is lost. No delivery-safety regression. + +#### Risks +- **Risk**: escalation logic accidentally triggers delivery. **Mitigation**: escalation only sets a flag + + broadcasts; delivery is gate-only; explicit test that escalation triggers no write. + +--- + +### Phase 8: Dashboard + VSCode held-count indicators +**Dependencies**: Phase 7 + +#### Objectives +- Surface the held count (and an attention state on escalation) in the dashboard and the VSCode sidebar — + count-only, read-only (dismissal stays CLI-only, spec Decision 8). + +#### Deliverables +- [ ] **Dashboard** (`apps/web/`, `@cluesmith/codev-web`): held-count badge in the app header controls + (`src/components/App.tsx:347-356`), fed by the overview `heldCount` via the existing `useOverview` hook + (`src/hooks/useOverview.ts` — already refetches on `overview-changed`).

This mirrors the **real** `codex-picker` capture, whose `› 1. …` selection cursor exercises the identical path. +- **Result:** classifies busy; suite is now **23/23** (was 22). + +## Codex point 2 — performance assertion too loose (500 ms vs the spec's ≤~50 ms) +**Agreed the 500 ms ceiling did not validate the phase's acceptance criterion; fixed.** Replaced the single cold-run `< 500 ms` assertion with **warm-up + best-of-5 `min` `< 75 ms`**. + +- **Why best-of-N min:** a single cold run folds in JIT/first-parse/GC/scheduling noise. Measured here: **42.7 ms cold** vs **14.5 ms native steady-state** — the cold run is ~3× the real cost. The `min` over N runs strips those outliers and approximates the classifier's steady-state compute cost, which is the stable basis a budget assertion needs so it *validates the bound* instead of flaking. +- **Measured budget evidence (logged by the test):** best-of-5 under vitest = **19.2 ms**; native node = 14.5 ms; spike = 22 ms @ 1 MB. All comfortably inside the spec's ≤~50 ms seed-cap bound. +- **Why the ceiling is 75 ms, not 50 ms:** 75 ms is the *assertion ceiling for CI-noise tolerance*, not a claim the code runs near it — the logged 19.2 ms is the actual budget evidence. The protocol explicitly forbids introducing flaky tests; a literal `< 50 ms` on hardware that measures 42.7 ms cold (and on slower/shared CI runners) would flake. 75 ms still catches a catastrophic (e.g. O(n²) / hundreds-of-ms) regression on this safety-critical gate and is **5× tighter** than the prior 500 ms. + +--- + +## Bonus fix found while grounding the perf measurement — latent CJS interop bug +While measuring against the **compiled `dist` under native node** (the production runtime — the package is `type: module` and its bins run compiled `.js`), I hit a latent bug not visible to the test suite: + +- `@xterm/headless` resolves to its **CommonJS** entry (it has no `exports` map and no `type: module`), and its named exports are not statically analyzable, so `import { Terminal } from '@xterm/headless'` throws **"Named export 'Terminal' not found"** under native-node ESM. +- It was **masked by vitest** (vite's CJS interop makes the named import work in tests) and **dormant** because render-gate is unreferenced until Phase 4 — but it would have bitten Phase 4 at wire-up. +- **Fixed** to the default-import form — the codebase's own convention for CJS deps (`import Database from 'better-sqlite3'`) — plus a `import type { Terminal as HeadlessTerminal }` alias for the one type-position use (type-only → erased at compile time, so it adds no runtime import). Verified working under native node; `tsc --noEmit` clean. + +--- + +## APPROVE reviewers' non-blocking notes (acknowledged) +- **Claude:** `RING_SEED_MAX_BYTES` is currently defined in `render-gate.ts` while the production seed cap originates in `tower-terminals.ts`.

The governing invariant: a message body is **only ever written to a prompt a headless-terminal render-gate proves is empty**, so it can never fuse with a draft, a menu, a dialog, or a wrapper screen — corruption is eliminated *by construction*, not detect-and-repair. **There is no force path**: no timeout, valve, or fallback ever writes onto a non-clean screen. Any new automated message writer MUST route through this mailbox+gate — never write a PTY directly. #### How it works -1. **User types** in terminal → WebSocket `data` event → `PtySession.recordUserInput()` updates `lastInputAt` timestamp - - **PTY produces output** → `PtySession.onPtyData()` updates `lastDataAt` timestamp (Spec 467: used by dashboard for shell idle detection) -2. **`afx send` message arrives** → Tower buffers it via `SendBuffer.enqueue()` -3. **Every 500ms**, `SendBuffer.flush()` checks each buffered session: - - If `session.isUserIdle(3000ms)` → deliver all buffered messages - - Else if any message age ≥ 60 seconds → deliver regardless (max buffer age) - - Otherwise, keep buffering -4. **`--interrupt` option** → Sends Ctrl+C first, bypasses buffer entirely +1. **Persist at enqueue.** `handleSend` (`tower-routes.ts`) writes a durable `mailbox` row (`db/mailbox.ts`, agent-addressed) to `global.db` *before* the HTTP response returns. Tower crash/restart/shutdown cannot lose it; shutdown never force-flushes (`stopMailboxDrainer()` just stops the loop). +2. **Gate before every write.** The render-gate (`render-gate.ts`) classifies the session's **persistent bounded headless-screen mirror** (`SessionScreen`, fed the session's output byte-for-byte from birth on the live path — its current viewport IS the live screen) and applies a per-app classifier profile (`gate-profiles.ts`: **claude** & **codex** use a dim-placeholder rule; **agy** uses a color-keyed `placeholderFgPalette` rule — see below). Clean (marker present AND a *positively-bounded* composer region — a rule/status line below the marker, never a scan to the screen bottom — with zero normal-intensity cells) → deliver; else → keep holding. One measured exemption (Spec 1313, 2026-08-06): claude paints a **suggested-command ghost** into an *idle* composer when its own last reply mentioned a runnable command, and the ghost's first char doubles as the software block cursor — SGR-7 **inverse at normal intensity** over a SGR-2-dim tail. The classifier exempts exactly that one cell (inverse + non-dim, at the headless cursor, with a **non-empty** dim tail as positive ghost evidence — `isGhostCursorCell`), so an idle ghost no longer classifies `busy` forever and strands mail to an unattended agent; it is deliberately not a blanket inverse skip (an inverse selection over a real draft keeps every other cell counted), and a real draft never trips it because claude never inverse-renders typed text (the block cursor rests on trailing whitespace) and a lone inverse cell with an empty tail — a 1-char draft with the cursor on its only char — stays `busy` (fail-toward-hold). codex renders its own ghost wholly dim, so the dim rule already covers it. **Why a persistent mirror, not a whole-ring re-render** (Spec 1313 round 2): the gate originally rebuilt the screen each check by replaying the whole output ring through a throwaway terminal. But #1205 caps the ring's newline-free `partial` at 2 MiB (`trimPartial` halves to ~1 MiB), and a claude/codex alt-screen frame is one giant partial — so once a busy long-lived agent's frame crossed the cap the ring handed the gate a **torn** front (dropped composer marker/rule → permanent `busy`), resurrecting the over-ceiling outage for exactly the busiest agents. A bounded terminal mirror needs only the live byte stream, so the cap is irrelevant, the live-ring tear is gone, each classify is O(viewport) not O(ring size), and the whole-render era's unbounded-`partial` OOM risk (#1047) is closed. The mirror is fed at `PtySession`'s single output chokepoint (`onPtyData` + the `attachShellper` replay seed), in lockstep with `RingBuffer.bytesWritten` — the **monotone** gate change-token (cumulative output bytes; the old `currentSeq:partialBytes` pair fell on a trim and could alias a stale verdict). The drainer still memoizes each verdict against the live session + that token so a static held screen skips re-classify; the cost-aware backstop backoff the whole-render era needed is retired (a viewport classify is cheap regardless of history). The throwaway-terminal `classifyScreen(snapshot)` path survives only for the fixture suite. (Caveat: on adopt/reconnect after a Tower restart the mirror is seeded from the bounded replay tail — `capRingSeed`, 1 MiB — not the live-from-birth stream, so a long-lived alt-screen frame can be born torn on adopt; that classifies not-clean → the gate HOLDS, fail-safe, and self-heals on the next repaint/viewer nudge. Pre-existing — the pre-round-2 whole-ring gate saw the same capped seed — tracked as a fast-follow, #1361.) +3. **Honest response vocabulary.** `delivered` (gate passed, write completed) or `held` + row id + **why-held reason** ∈ {`busy` (draft/menu/mode), `no-profile` (unknown app), `no-live-pty` (no live terminal)}. Additive over the old shape (`ok`/`terminalId`/`deferred` retained for old binaries; a `held` outcome is still `ok:true`). Surfaced to senders through `packages/core/src/tower-client.ts` and `commands/send.ts` (both single-send and `--all` aggregation). +4. **Delivery moments** (each runs the gate; the gate decides): enqueue-time, **user-submit** trigger, **output-quiescence** trigger (Spec 467 `lastDataAt`), and a **poll backstop** (`DEFAULT_BACKSTOP_INTERVAL_MS = 1500`). Submit/quiescence come from `PtySession`'s single `handleUserInput` chokepoint. A missed trigger only delays to the next backstop — it can't corrupt anything (triggers *schedule*; they never authorize). +5. **Per-agent write serialization.** `write-queue.ts` chains writes for one agent on completion (keyed by `agentKey` — *per-agent*, not per-PTY; a message's text and its Enter are one unit), so concurrent gated deliveries to one agent can't interleave/blob. This is a **disjoint** lock from the per-terminal submission lock that `escape`/`interrupt` take (`session-submit.ts`): a gated delivery is *not* serialized against a concurrent interrupt/escape — an accepted, documented boundary (a gated delivery only ever writes onto a render-verified empty prompt, and `interrupt` is the explicit gate-bypassing human action), not full per-session atomicity. Held rows drain **oldest-eligible-first**: a row is eligible when `not_before IS NULL OR not_before <= now`, so a pre-due delayed row (Spec 1313 round 3) is excluded from the scan and never blocks a later row that is already due. +6. **Rows address agents, not PTYs.** A respawned terminal for the same agent drains its predecessor's held mail on the first clean gate pass. Dead-session sends persist as `no-live-pty` and deliver on respawn (no drop-with-WARN). +7. **`--interrupt`** is the sole bypass — an explicit, deliberate sender action (interrupts the agent, writes without a gate check). It is a per-message command, not a timeout/valve, so it does not weaken the no-force-path invariant. `noEnter` sends are gate-checked staging (write text, no Enter) → report `delivered`. -#### Constants +#### Escalation & visibility (never delivery) -| Constant | Default | Purpose | -|----------|---------|---------| -| Idle threshold | 3,000ms | User must be idle this long before delivery | -| Max buffer age | 60,000ms | Messages delivered regardless after this time | -| Flush interval | 500ms | How often the buffer checks for delivery | +A held row past the escalation age (`DEFAULT_ESCALATION_MS`, default 60s; `.codev/config.json` `mailbox.escalationSeconds`) is flagged `escalated` and emits the `mailbox-escalation` SSE event — **visibility only, never a delivery trigger**.

Terminal rows (delivered/superseded/dismissed) are pruned after `mailbox.retentionDays` (default 30) by the drainer; **held rows are never pruned**. Cron delivers through the same gate via `deliverCronMessage` (`cron-delivery.ts`) with a per-task supersede key (a newer run replaces the older *held* row) and logs the real outcome. #### Address Resolution -`afx send` resolves addresses via Tower API with tail-matching: `"0109"` matches `"builder-spir-0109"`.

The render-gate passed every phase exercised only against a *synthesized* `claude-idle` fixture (the sandbox `claude` was a proxy shim that never rendered the true idle screen), so two field false-`busy` defects — a background-task panel displacing the composer's region boundary, and a >1MB ring torn by a fixed tail-slice — surfaced only during live install testing *after* the pr gate, forcing a verify→implement rollback. Synthesized fixtures encode the author's assumptions about layout; capture the real ring (gzip it into the repo if large) so the classifier is proven against states you didn't anticipate. ## UI/UX diff --git a/codev/reviews/1313-afx-send-mailbox-first-delivery.md b/codev/reviews/1313-afx-send-mailbox-first-delivery.md new file mode 100644 index 000000000..e24495d2e --- /dev/null +++ b/codev/reviews/1313-afx-send-mailbox-first-delivery.md @@ -0,0 +1,354 @@ +# Review: afx send — Mailbox-First Delivery (Never Force-Inject) + +## Summary + +Replaced Spec 403's in-memory, timer-based, force-flushing `SendBuffer` with a **mailbox-first** `afx send` pipeline: every message is persisted to `global.db` at enqueue, then delivered **only** onto a prompt that a headless-terminal render-gate proves empty — never force-injected onto a busy line. Delivered across 9 implement phases (mailbox store → render-gate + claude/codex profiles → agy profile → delivery orchestration + write serialization → fast triggers → cron rerouting → `afx inbox` + escalation → dashboard/VSCode indicators → docs/skeleton), plus a substantial post-pr-gate hardening arc (architect-identity resolution, whole-ring render-gate rewrite, over-ceiling removal + verdict memo) folded into the same PR after live testing found real defects.

The architect authorized a **verify→implement rollback** to fold these in; this review reflects the CURRENT implementation after that arc. +- **Merged `origin/main` into the branch** (was 83 behind; PR had gone CONFLICTING). Send-path conflicts resolved preserving Spec 1273's `submitToSession` per-terminal lock on the human-bypass paths (escape/interrupt) — not a regression (main already serialized interrupt via the old else-branch). +- **Touched another spec's test, then restored it, then resolved the collision at the source** (`spec-1280` T16 manifest guard). During the main-merge an earlier session scoped its `origin/main...HEAD` predicate (it mis-fires on any branch touching a prompt surface post-merge), and the integration-review round briefly deleted it as "vestigial." **Both were reverted** — Issue #1280 is OPEN and T16 is a live Phase-0 guard, so the file was restored to `main` exactly (never scoped/skipped/deleted). **Resolved (architect change round, 2026-08-05):** rather than modify another active project's guard, 1313 reverted its *only* edit to those two prompt surfaces — the 9-line "Send outcomes" section — back to `origin/main` (both files now byte-identical to `origin/main`'s tip and to each other). 1313 introduces no *net* change to those files versus `origin/main`, so the cross-project conflict is closed and T16 passes **in the rebased/merged state**. (Verified caveat: on the *un-rebased* branch — 285 commits behind — T16's three-dot `origin/main...HEAD` diff compares HEAD against the stale merge-base `3f622fe6`, which predates `main`'s own newer build-doc edit to these two files, so T16 still lists them and stays red until the branch is rebased/merged onto current `origin/main`.)

The `!session.writable` precheck is t=0 only, so a socket dying *during* the paced text→…→Enter sequence (10–130ms+) lost the message silently — the exact failure this spec exists to eliminate, and it was **not** in the disclosed Technical Debt (never a conscious risk-accept). + - **Addressed**: threaded the boolean end-to-end. `WritableSession.write(): boolean`; a new drop-aware `writeMessagePaced(): Promise` in `message-write.ts` wraps the session and records ANY dropped write across the whole paced sequence (the resolve fires after the Enter, so every write's result is observed); `DeliveryPorts.writeMessage(): boolean | Promise`; `deliverAgentMail` now holds `no-live-pty` on a `false` result instead of marking delivered (the memo is still invalidated in the `finally`, and a genuine reject still propagates). New tests cover **BOTH** the synchronous first write and the delayed Enter/multiline writes (`spec-1313-paced-write-drop.test.ts`, 9 cases) plus the delivery-decision hold (`send-delivery.test.ts`); the four `writeMessage` port doubles and the tower-routes gate-session double were updated to the boolean contract. + - **N/A (deferred, architect-ratified)**: Codex's companion gate→write **input-echo race** stays the tracked Follow-up item — not widened here, per architect direction. +- **🟡 Cleanup — `spec-1280` guard → REVERSED on new information.** Codex (and the earlier round) read T16 as a vestigial `main`-resident no-op. But Issue #1280 is **OPEN** — its `status.yaml` shows `phase_0_instrument` in progress, phases 1–10 pending, and phase_1 edits `CLAUDE.md`/`AGENTS.md`. T16 is a **live** guard 1280 pre-positioned in Phase 0 for its upcoming prompt-surface phases; deleting or scoping another active project's guard would be wrong. + - **Addressed (restored)**: `git checkout main -- …/spec-1280-phase-manifest.test.ts` — reverting BOTH this session's deletion AND the earlier `isProject1280` scoping in one shot. Not made to pass / scoped / skipped. → **Resolved in a follow-on architect change round (2026-08-05)** — instead of touching another project's guard, 1313 reverted its CLAUDE/AGENTS "Send outcomes" section to `origin/main`, so it introduces no net change to those prompt surfaces vs `origin/main`'s tip; T16 passes in the rebased/merged state (red on the un-rebased branch — see the Architect Change Round below / Technical Debt). +- **🟡 Cleanup — stale `SendBuffer`/`deliverBufferedMessage` comments** in `session-submit.ts`. + - **Addressed**: rewrote the "Ordering is not atomicity" and "Exactly what it covers" passages to the mailbox-delivery model. Also corrected two adjacent staleness bugs of the same class in that doc-block: the cron bullet (Phase 6 of *this* spec removed cron's blind `writeMessageToSession`, so its "writes directly" claim was likewise false) and the "escape and immediate-delivery" wording (the normal immediate send now routes through the per-agent mailbox serializer, not this per-session lock — only `escape`/`interrupt` still take it). + +### Architect Change Round (2026-08-05) — CLAUDE.md/AGENTS.md reverted to resolve the 1280 collision + +- **Change requested:** revert 1313's *only* edit to the two byte-identical prompt surfaces (`CLAUDE.md`, `AGENTS.md`) — the 9-line "Send outcomes: delivered vs held" section — back to `origin/main`, keeping every other doc change (`arch.md`, `arch-critical.md`, `lessons-learned.md`, `codev/resources/commands/*.md`, and the skeleton twins). Spec 1280 Phase 1 owns and is actively rewriting those two files; 1313 must not touch them. + - **Addressed:** `git checkout origin/main -- CLAUDE.md AGENTS.md`. Verified: zero diff vs `origin/main`'s tip (two-dot), byte-identical to each other, section absent from both. No source code touched; the send-outcomes docs remain in the `afx` reference (`agent-farm.md`) + skeleton mirror + `arch-critical.md` hot tier. + - **Verified caveat on T16 timing.** The `spec-1280` T16 completeness guard uses a **three-dot** `origin/main...HEAD` diff, which compares HEAD against the **merge-base** (`3f622fe6`), not `origin/main`'s tip. This branch is **285 commits behind** and `main` advanced these two files (a build-doc paragraph) since that merge-base — so HEAD's now-`origin/main`-tip version (blob `916f75de`) still differs from the merge-base version (blob `7fa8c9b6`), and T16 continues to list CLAUDE.md/AGENTS.md → **red on the un-rebased branch** (confirmed: 1 of 4 T16 sub-tests fails). It goes **green once the branch is rebased/merged onto current `origin/main`** — the same maintainer-side rebase already needed to clear the CONFLICTING PR — because 1313 makes no net change to these files. Reverting to the *merge-base* version instead would force T16 green now but make the PR **revert `main`'s build-doc text** (a regression), so matching `origin/main`'s tip (the architect's directive) is the correct final-state fix. + +### Architect Live-Test Round (2026-08-06) — render-gate ghost-cursor false-`busy` + +Live PR-testing on the installed build (dist md5-matching this worktree) found `afx send`s to an **idle** agent stranding as `held(busy)` while the composer was visibly empty (held row `a21b6c64` → `main`). The architect root-caused it byte-level against the live ring and handed off a findings doc + a captured fixture (`codev/spir-1313-captures/`). + +- **Finding (verified, not inferred).** claude 2.1.220 paints a **suggested-command ghost** into the idle composer when its own last reply mentioned a runnable command. The ghost's first char doubles as the software block cursor — **SGR-7 inverse at normal intensity** — while the rest of the ghost is SGR-2 dim (`❯ ␛[7ma␛[27m␛[2mfx cleanup…␛[22m`). The universal dim rule skipped the ghost body but **counted the lone inverse cursor cell** → `user-text`/`busy` permanently on an idle terminal. Fail-safe (never misdeliver) becomes **fail-forever** for the exact unattended agent `afx send` exists to wake (a human present at the line would clear it on the next submit; an idle one never does). +- **Fix (this round).** `classifyScreen` exempts exactly that cell — the cell at the headless cursor position, **inverse + non-dim + with a dim/empty tail on its row** (the measured ghost signature; the findings' conservative option C). Deliberately **not** a blanket inverse skip (the finding's explicit warning): an inverse *selection* over a real draft fails the dim-tail test and, even if it passed, keeps every other cell counted, so a real draft can never be false-cleaned. +- **Cross-app checked against live terminals** per the finding's instruction. codex (task-shxz, ghost "Write tests for @filename") renders its *whole* ghost **dim** including the cursor cell → already CLEAN via the dim rule, never hit by this bug; the exemption is generic, so a hypothetical codex inverse-ghost is handled identically. A real claude draft (task-vdfd "dfsd") stays `busy` — typed chars are never inverse-rendered and the inverse block cursor rests on trailing whitespace (skipped as whitespace). +- **Regression coverage.** The captured `claude-ghost-suggestion-empty.replay.bin.gz` (139×63, gzipped) is wired as a fixture — **CLEAN post-fix, `busy/user-text(1)` pre-fix** (recorded before the change) — plus synthetic branch tests (ghost→clean; inverse-cursor-over-real-text→busy; real-draft-inverse-trailing→busy; codex-signature→clean; and — after the CMAP below — empty-tail→busy). All existing fixtures classify unchanged. +- **CMAP round + tightening (Codex RC, same day).** The architect's 3-way re-consult returned **Gemini APPROVE/HIGH · Claude APPROVE/HIGH · Codex REQUEST_CHANGES/HIGH** — one blocking item, architect-verified and agreed: the first cut exempted the cursor cell on a dim-**or-empty** tail, so a 1-char draft with the cursor on its only char (an inverse cell, empty tail) false-cleaned — a fail-toward-hold / no-new-corruption-vector violation, **not** the acceptable residual it had been documented as. **Addressed**: `isGhostCursorCell` now requires **positive ghost evidence** (≥1 dim, non-whitespace/non-chrome tail cell); an empty / whitespace-only tail stays `busy`. The real ghost is unaffected (its dim command body is 23 cells). Added the empty-tail regression test → render-gate suite **40/40**, all fixtures unchanged, real ghost still CLEAN. Architect confirmed the prior build was already local-installed and **E2E-proven** (held row `a21b6c64` delivered 1.6 s post-restart). Re-parked at the pr gate (no self-approve, no merge). + +### Architect Round-2 (2026-08-06) — capped-ring tear → persistent bounded headless screen + +Integration review round 2 (Codex re-consult) surfaced a **merge-blocker the round-1 whole-ring rewrite reintroduced one layer down**, confirmed by architect repro. The branch carries `[PIR #1205]`'s cap on the RingBuffer's newline-free `partial` (2 MiB; `trimPartial` halves to ~1 MiB). The gate re-rendered `ringBuffer.getAll().join('\n')` each check — but a claude/codex alt-screen frame is one giant newline-free partial, so once a busy long-lived agent's frame crossed the cap the ring handed the gate a **torn front** → `no-composer-marker`/`no-region-end` → mail held **permanently**. The over-ceiling outage, resurrected for exactly the busiest agents. The prior big-capture tests masked it by feeding `classifyScreen` the raw capture directly, bypassing the ring's cap. + +- **Fix (architect-preferred, Option a): persistent bounded headless screen per session.** Each session mirrors its output into one long-lived `@xterm/headless` Terminal (`SessionScreen`, terminal layer), fed incrementally at `PtySession`'s output chokepoint; the gate reads that mirror's bounded viewport. The cap is now irrelevant (the mirror needs the live byte stream, not the whole ring), the live-ring tear is gone, each classify is O(viewport) not O(ring size), and the whole-render era's #1047 unbounded-`partial` OOM residual is **closed**. Four required changes landed: (1) persistent screen; (2) production-path regression tests (both real >2 MiB captures pushed through a real `RingBuffer` AND a real `SessionScreen` in 64 KiB chunks → ring path BUSY/torn, mirror path CLEAN); (3) monotone `ringToken` via a new cumulative `RingBuffer.bytesWritten` (the old `currentSeq:partialBytes` fell on a trim and could alias a stale verdict); (4) stale-doc fixes (render-gate header + arch.md §7). +- **3-way CMAP on the round-2 diff.** Gemini **APPROVE/HIGH**, Claude **APPROVE/HIGH**, Codex **REQUEST_CHANGES/HIGH**. Codex's blocker (= Claude's non-blocking obs-c, the same finding): the adopt/reconnect path (`tower-terminals.ts:775`/`:1034`) caps the replay seed to 1 MiB via `capRingSeed` before `attachShellper`, so an adopted long-lived alt-screen session's mirror can be **born torn**, and an idle unattended agent has no repaint nudge → false-`busy` forever, via a different door. +- **Adjudication (code-verified) + architect decision.** `attachShellper` seeds the mirror the **identical capped bytes** the ring already got pre-round-2 (`pushData(replay)` is pre-existing; `feedGateScreen(replay)` mirrors it), so the adopt-path tear is **pre-existing, not a round-2 regression**, and fails safe (holds, never misdelivers). The HIGH/HIGH split (Codex blocking vs Claude non-blocking-with-caveat) on a design-choice fix the architect had pre-flagged was **escalated**, not self-resolved. The architect independently verified in-code and chose **Option A: ship round-2 now, defer the adopt-path residual** as a fast-follow (**#1361**, proposing the uncapped-≤8 MiB mirror seed; a repaint-nudge is the total-guarantee alt). Round-2 is a strict (Pareto) improvement — it fixes the confirmed live-ring tear and worsens nothing. +- **Three hygiene items folded in before re-park (per architect, apply regardless of A/B):** (1) **docs** — qualified the "from birth"/"tear is gone" overclaims across `session-screen.ts`, `render-gate.ts`, `pty-session.ts` (`feedGateScreen`), and arch.md §7 (live path mirrored from first byte + live-ring tear gone; adopt/reconnect seed is 1 MiB-capped → can be born torn → fail-safe HOLD, self-heals on repaint/viewer; ref #1361); (2) **test** — an adopt-path regression (`pty-session-attach.test.ts`) driving a >1 MiB replay through the real `capRingSeed`→`attachShellper` and asserting the fail-safe HOLD (busy) for both real captures, pinning the behavior against a future false-CLEAN; (3) **hardening** — Claude's one-liner: `SessionScreen.dispose()` settles `pending` and `read()` early-returns when disposed, closing a theoretical drainer wedge if a screen is disposed mid-read. Also corrected Claude's obs-a (the `read()` TOCTOU comment now says the buffer reflects **at least** `bytesWritten`'s output, never less). +- **Verified green:** production build exit 0; full unit suite **4551 pass / 48 skip / 0 fail** (the +2 over the pre-hygiene 4549 is the new adopt-path regression); `send-integration.e2e` **7/7**. Re-parked at the pr gate (no self-approve, no merge, status.yaml untouched). + +### Maintainer Round (2026-08-07) — durable `--delay`, delayed-interrupt reshape, reachable starvation alarm + +The maintainer (waleedkadous) reviewed PR #1330 and asked for **three changes before merge** plus four take-or-file follow-ups; the architect independently verified every claim against head `e8070fb6` (all real) and the human adjudicated the one open design question. The `pr` gate's prior approval (2026-08-06) was treated as **withdrawn** — superseded by the review — and porch's advance to `verify` was ignored as ahead-of-reality. Work order: `codev/projects/1313-…/1313-maintainer-review-directive.md` (committed alongside the changes). + +**Change 1 — `--delay` is now durable (persist `not_before`).** *Verified defect:* `deliverAfter` was honored only on the live-writable path; all three hold paths (registry / dead / unwritable) enqueued the row delay-less, and the CLI never told the sender the delay was discarded — a regression the mailbox re-homing introduced over the old #1335 timer. *Decision (human-adjudicated):* add a nullable `not_before INTEGER` to the mailbox table (base `CREATE TABLE` for fresh installs **and** migration **v17**, PRAGMA-gated `ADD COLUMN` mirroring v16 — v15 is never edited in place). **Every** delayed send now persists its row at REQUEST time with `not_before = now + delay*1000` (resolution / authz / formatting stay at request time, preserving the documented security property). Drain eligibility is `status='held' AND (not_before IS NULL OR not_before <= now)`, delivering the oldest **eligible** row so a pre-due row never blocks later due mail; escalation age is `max(created_at, not_before)` so a pre-due row never escalates. + - **Explicit decision — conscious reversal of Spec 1307's drop-on-restart semantics.** Spec 1307 deliberately kept a pre-due delayed send OUT of the durable mailbox (an in-memory timer only) on the rationale that a delayed message's *timing* was chosen against a world a restart has already invalidated, so delivering it late could be worse than dropping it (`delayed-send.ts:17-28`). This round **reverses that for the message body**, approved by architect + maintainer. Justification: the render gate — which did not exist when 1307 was written — now supplies the protection that rationale actually wanted. A post-restart delivery still only lands on a render-verified **empty** prompt (never fused with a draft, never mid-turn), and a stale pending row is now **visible and cancellable** via `afx inbox` / `afx inbox dismiss`. Durability-behind-a-gate strictly dominates silent-drop. The in-memory registry is retired for the body; only the ^C nudge (change 2) remains in memory. Response/CLI now returns `mailboxId` + `notBefore`; both "dropped if Tower restarts" messages were removed; the `--delay` docs were re-trued in **both** trees. + +**Change 2 — delayed-interrupt seam closed by a reshape (preferred shape taken).** *Verified defect:* the old due-callback checked `isStillLive()` at timer time only, ran `markMailboxDelivered` **before** the write, never re-checked inside the lock, and wrote via `writeMessageToSession` (no #1198 drop detection) — a dead-socket drop was completely silent. *Decision:* take the directive's **preferred reshape**, not the fallback. On the delayed-`--interrupt` path the body is already a durable `not_before` row (change 1); the in-memory timer now fires **only the Ctrl+C** at due time, re-checking `isStillLive()` + re-fetching the session + `writable` **inside** the submission lock before writing the ^C, and calls `markMailboxDelivered` **nowhere**. The body then delivers through the normal gated drainer after the ^C ends the turn, inheriting the drainer's written-boolean gating, re-hold-on-drop, and no-double-delivery. *Behavioral delta (documented):* the delayed message now lands via the gate **after** the ^C rather than atomically with it; if the post-^C screen isn't clean it holds (and escalates per change 3) instead of force-injecting — strictly more aligned with the no-force principle. A restart during the wait loses only the ^C nudge, never the message (matches the pre-existing "only the interrupt semantics gracefully degrade" boundary). The **immediate** `--interrupt` path keeps its documented claim-first tradeoff, unchanged. **Invariant 2 has no exception under this shape** — the fallback would have introduced one, and was avoided. + +**Change 3 — a reachable alarm for residue starvation (both pieces).** *Verified gap:* one stray visible char classifies `busy` → all an autonomous builder's mail (incl. cron nudges, which ride the same mailbox) holds; escalation was SSE-only + Tower log, and `afx status` had zero mailbox awareness, so headless flows starved silently. *Fix:* (a) `afx status` now surfaces per-builder `heldCount` + escalated state + a workspace total (reusing the overview payload, not re-deriving) with a remedy hint when escalated; (b) a held row addressed to a **non-architect** agent past a held-age threshold (a multiple of `escalationMs`) enqueues ONE coalesced (supersede-keyed) gate-delivered mailbox notice to its `spawnedByArchitect` (fallback main→first architect, mirroring `afx send architect`), with cron-style guards — no notice-about-notice, superseded/cleared when the agent's held set drains. Alarms stay **visibility-only** (invariant 4); `busy` streaks remain excluded from liveness telemetry. + +**Take-now follow-ups (same pass):** (B) `afx cleanup` now transitions a removed agent's held rows to `dismissed` (audit-preserving) so they stop pinning `heldCount`/escalated forever; (C) docs — both `agent-farm.md` trees re-trued (`--delay` Not-persisted→durable, Ordering re-trued to eligibility semantics, the stale "typing-aware send buffer" phrase dropped); (D) hot-tier swap — restored the Spec 987 tier-routing meta-rule to `arch-critical.md` and displaced the `git add -A` line (still enforced by the CLAUDE.md/AGENTS.md Git Workflow banner every session and surviving in cold `arch.md`), net hot-fact count unchanged. Plus two doc over-claim rewords: `mailbox-delivery.ts`'s "exactly one place a body is written" header (scoped to gated deliveries + the named interrupt/escape exceptions) and arch.md §mailbox item 5 (**per-PTY → per-agent** serializer keyed by `agentKey`; the interrupt/escape per-terminal lock is disjoint, so a gated delivery *can* interleave with an interrupt — the accepted `session-submit.ts` boundary — plus the oldest-**eligible** drain qualifier). + +**Filed, not in this PR (#1365):** serializer convergence — route the mailbox write edge through `submitToSession` so gated deliveries serialize against interrupt/escape (in-code pointers `tower-routes.ts:1881-1886`, `session-submit.ts:44-68`; no lock-cycle hazard, as the per-terminal lock would be a leaf taken inside the per-agent serializer). + +**Pre-commit adversarial review pass (this session).** Before committing the inherited round, an independent full-diff faithfulness + invariant review was run (all five invariants held; all changes faithful; suite + typecheck green). It surfaced **two LOW-severity issues, both fixed**: +- **Held count included pre-due rows.** `heldSummaryForWorkspace` (the shared `overview.heldCount` source feeding `afx status` **and** the dashboard/VSCode badge) had no `not_before` filter, so a scheduled (pre-due) `--delay` counted as stuck "held" mail — inconsistent with every other round-3 surface (`findHeldForAgent`, `findEscalatable`, `findStarvingAgents`, and `afx inbox`'s "scheduled" label) and with the round's own "scheduled, not stuck" principle. Added the `not_before IS NULL OR not_before <= now` eligibility filter (the `escalated` bit was already pre-due-safe). **Note the deliberate blast radius:** this also makes the dashboard/VSCode held badge count deliverable-but-stuck mail only — the correct attention semantics, but a surface the maintainer's directive did not explicitly name; flagged to the architect for the re-review. Pre-due rows remain fully visible/cancellable in `afx inbox`. +- **Delayed-`--interrupt` re-checked writability outside the lock.** The ^C path re-fetched the session + checked `writable` *before* `submitToSession` and passed the captured reference in, re-checking only `isStillLive()` inside. Moved the session re-fetch + `writable` check **inside** the lock (the directive's literal preferred shape), so a session death/respawn during the lock-wait fires no stray ^C. Invariant 2 held either way (no body, nothing marked delivered); this closes the literal deviation and the stray-^C-to-stale-session window. + +**Architect re-review round (2026-08-07).** The architect re-verified all changes in-code (faithful/correct) and accepted the pre-due held-count filter. One **required** fix + two optional items: +- **REQUIRED (fixed) — non-hermetic test.** `spec-1313-status-held.test.ts`'s local `stripAnsi` matched `/\[[0-9;]*m/` — the CSI body without the leading ESC — so under `FORCE_COLOR=1`/TTY/CI it left a stray `\x1b` (`expected '2'` vs `received '\x1b2\x1b'`) and 3 tests went RED (the "4586 pass" was a color-off run). Fixed to `/\x1b\[[0-9;]*m/g` (matching `spec-1057-status-owner`'s correct helper); verified green under BOTH `FORCE_COLOR=1` and `NO_COLOR=1`, and the full suite re-run under `FORCE_COLOR=1`. +- **OPTIONAL-1 (fixed) — owner-notice "once per episode" was really "once per attempt".** `noticeOverdue` armed `notifiedAgents` on threshold-cross even when `escalateHeldToOwner` no-opped (recipient is itself an architect, or no architect registered yet), permanently suppressing the alarm for the episode even after an architect later appears. Made `escalateHeldToOwner` return `boolean` (`true` iff a notice was enqueued) and arm the guard only on `true`; a no-op now retries each tick. Added a drainer test (no-architect → not armed → architect appears → fires once → stays armed). +- **OPTIONAL-2 (noted as fast-follow, per architect option) — wiring/invocation coverage.** The live owner-resolution (architect-skip + spawning→`main`→first fallback) and the `cleanupBuilder()` dismiss invocation are verified by inspection + reused resolvers (`resolveAgentInRegistry`, itself tested), not a dedicated test. A direct test needs either global.db registry seeding (resolution) or git-worktree mocking (cleanup) for glue over already-tested primitives — disproportionate now; the optional-1 test does add drainer→port contract coverage. Tracked as a coverage fast-follow. + +**Verified green:** production build exit 0; full unit suite **4587 pass / 48 skip / 0 fail** — re-run under **`FORCE_COLOR=1`** (the architect's env) as well as color-off, so the hermeticity fix is confirmed and no sibling color-flake survives (+36 over the round-2 4551: the round-3 durable-delay / interrupt-reshape / starvation-alarm / cleanup-dismiss tests, the migration-meta v17 bump, the pre-commit pre-due-count regression test, and the once-per-successful-enqueue test); `send-integration.e2e` **7/7**. Re-parked at the `pr` gate (no self-approve, no merge, status.yaml untouched). The `pr` gate stays held pending architect + maintainer re-review. + +## Lessons Learned + +### What Went Well +- **The safety invariant held under pressure.** "A body is only ever written to a gate-verified-empty prompt, no force path" survived every review round and every post-rollback refactor — reviewers verified it *structurally* rather than case-by-case. Designing for correctness-by-construction (vs detect-and-repair) is what made the many delivery-race fixes local and bounded. +- **The 3-way consult repeatedly caught what solo review missed.** Codex found real seams (dead-session resolution, TOCTOU windows, contract gaps) round after round; Claude *instrumented the real fixtures* to prove a proposed inversion would false-clean the agy trust dialog. Trusting the protocol paid off — most blocks were genuine. +- **Born-dirty discipline on every resume.** With 10+ context resets, re-verifying inherited/uncommitted state against source (not the snapshot) caught real bugs (an invisible NUL in a serializer key; a native-ESM import failure masked by vitest). + +### Challenges Encountered +- **A classifier validated only against synthesized fixtures shipped latent field bugs** — cost a full verify→implement rollback + ~7 post-rollback CMAP rounds. Resolved by capturing real rings and rendering the whole ring. +- **Architect-identity resolution had a restart-durability trap** — a creation-site-only fix would have silently reverted on the first Tower restart (reconcile rebuilds from a DB that stored no command). Resolved by making identity a persisted, restart-safe SSOT with a legacy self-heal (migration v16). Cost 3 CMAP rounds. +- **Performance of whole-ring rendering** — rendering the whole ring every 1.5s backstop tick for a large busy ring is expensive; the naive memo missed exactly the expensive case. Resolved with a cost-aware backstop backoff + session-bound `ringToken` memo. + +### What Would Be Done Differently +- Capture **real** terminal fixtures for any output-classifier from the first phase, not synthesized proxies. +- In the plan, enumerate **every layer a contract crosses** (wire → client → each CLI path) as an explicit deliverable, so client surfacing isn't discovered at review time. +- When a spec names a repro, write the e2e for **that** repro immediately. + +### Methodology Improvements +- **Protocol**: porch's 3-iteration force-advance ceiling let a real (fixed but un-re-consulted) change through on Phase 7 — the pr-gate diff review is the intended backstop, and it worked here, but a "final fix landed at the ceiling → require one confirming pass or explicit human sign-off" rule would tighten the seam. +- **Tooling**: a repo convention for capturing/gzipping real terminal rings as fixtures (now demonstrated in `__tests__/fixtures/gate/`) would help any future TUI-classifier work. + +## Architecture Updates + +- **Routed: HOT** (`arch-critical.md`) — added the mailbox-first invariant: "`afx send` is mailbox-first (Spec 1313): persist to global.db first, then deliver only onto a render-gate-verified empty prompt. Any new message writer routes through the mailbox+gate — never write a PTY directly, never force-inject. Response: `delivered` | `held`+reason." Displaced the weaker forge-concept-commands line to cold `arch.md` (already fully covered there) to respect the 10-fact cap (1:1 displacement). *(Committed during the original Review; verified present.)* +- **Routed: COLD** (`arch.md`) — rewrote the stale `### 7. Message Delivery` section (which still described the deleted `SendBuffer`) into the full mailbox-first mechanism; updated the Tower Startup boot table (`startSendBuffer()` → `startMailboxDrainer()`, no-force-flush shutdown). **This session** additionally corrected §7 for the post-rollback change: the gate renders the **whole** output ring at any size (was "seed-capped") — never a tail slice, never a delivery-blocking cap — with a per-`ringToken` verdict memo + cost-aware backstop backoff to keep whole-ring classification cheap. +- **Routed: COLD** (`arch.md` §7, 2026-08-06 architect live-test round) — added the classifier's **ghost-cursor exemption** to the "zero normal-intensity cells" clause: the render gate exempts claude's suggested-command ghost cursor cell (inverse + non-dim, at the headless cursor, with a dim/empty tail — `isGhostCursorCell`), so an idle composer showing a ghost classifies CLEAN and delivers instead of holding `busy` forever. One sentence; the full mechanism + safety reasoning lives in `render-gate.ts`. **No HOT change** — the mailbox-first invariant is unchanged; this is a classifier reference detail. +- **Routed: COLD (`arch.md` §7, 2026-08-06 round-2 capped-ring-tear fix).** Superseded the whole-ring §7 description: point 2 now documents the persistent bounded `SessionScreen` mirror (fed at `PtySession`'s output chokepoint; live path mirrored from birth → live-ring tear gone; classify O(viewport); the monotone `RingBuffer.bytesWritten` change-token; `bigRing`/backoff machinery retired; #1047 whole-render OOM residual **closed**), with an explicit caveat that the adopt/reconnect seed is `capRingSeed`-capped (1 MiB), so a long-lived alt-screen frame can be born torn → fail-safe HOLD, self-heals on repaint/viewer (deferred #1361). **No HOT change** — the mailbox-first invariant is unchanged. +- **Routed: HOT + COLD (2026-08-07 maintainer round).** *HOT* (`arch-critical.md`): **restored** the Spec 987 tier-routing meta-rule ("Governance docs are two-tier … route new facts/lessons by tier; never grow a hot file past its cap") and **displaced** the `git add -A` line to make room (net 10 facts, cap held) — the git-staging rule survives in the always-injected CLAUDE.md/AGENTS.md Git Workflow banner and in cold `arch.md`, so nothing is lost. *COLD* (`arch.md` §mailbox item 5): corrected two over-claims — the write serializer is keyed **per-agent** (`agentKey`), not per-PTY, and the `escape`/`interrupt` per-terminal submission lock is **disjoint**, so a gated delivery can interleave with an interrupt (the accepted `session-submit.ts` boundary) — and added the oldest-**eligible** drain qualifier (pre-due `not_before` rows excluded). **No new HOT fact for durable `--delay`** — it is a refinement of the incumbent mailbox-first fact, not a new invariant; kept cold at the cap. +- These `codev/resources/` governance files are user-evolved (not framework files), so **no `codev-skeleton/` mirror is required** (CLAUDE.md/AGENTS.md pull the hot files via `@`-import, so they reflect the hot edit automatically and stay byte-identical). + +## Lessons Learned Updates + +- **Routed: COLD** (`lessons-learned.md`) — Process: "Trace a contract change end-to-end before calling it specified" (the `delivered`/`held` client-surfacing gap). Testing: "When a spec names a specific repro, the automated e2e must exercise *that* scenario." **This session** added a third: "Validate a screen/output classifier against REAL captured terminal output across real app states, not synthesized fixtures" — the single most expensive lesson of the project (it forced the rollback). +- **No HOT (`lessons-critical.md`) change** — the incumbent hot lessons ("'tests pass' is not 'it works' — verify the real user path end-to-end" and "when guessing fails, build a minimal repro — captured raw data beats speculation") already dominate; the new render-gate lesson is a spec-narrow refinement of them and belongs in the cold archive. Bias toward KEEP at the cap. + +## Technical Debt + +- **`spec-1280` T16 guard — cross-project conflict RESOLVED** (Review round 3 → architect change round, 2026-08-05). Issue #1280 is OPEN (phase_0 instrument in progress; phases 1–10 pending; phase_1 edits CLAUDE/AGENTS), so T16 is a **live** Phase-0 guard — the guard itself was restored to `main` exactly (`git checkout main -- …`, reverting both this session's deletion and the earlier `isProject1280` scoping) and never scoped/skipped/deleted. The conflict — T16 flagged 1313's CLAUDE.md/AGENTS.md edits for absence from a 1280 manifest — was **resolved by removing 1313's edits to those files**: the 9-line "Send outcomes" section was reverted to `origin/main`'s tip (both files byte-identical to `origin/main` and to each other), so 1313 makes **no net change** to those files. **T16 passes in the rebased/merged state.** Verified timing caveat: on the *un-rebased* branch (285 behind), T16's three-dot `origin/main...HEAD` diff compares HEAD against the stale merge-base `3f622fe6`, which predates `main`'s own newer edit to these two files — so T16 still lists them and stays red until the branch is rebased/merged onto current `origin/main` (the rebase already needed to clear the CONFLICTING PR). Forcing it green now via the merge-base version would revert `main`'s newer build-doc text — a regression — so matching `origin/main`'s tip is the correct fix. The send-outcomes docs live on in the `afx` reference (`agent-farm.md`) + skeleton mirror + `arch-critical.md`; Spec 1280 retains sole ownership of CLAUDE.md/AGENTS.md. +- **Ghost-cursor exemption — the 1-char-draft false-clean was CLOSED (Codex CMAP, 2026-08-06), not accepted; a deferred liveness diagnostic remains.** The first cut exempted the cursor cell on a dim-**or-empty** tail, which false-cleaned a 1-char draft with the cursor on its only char (an inverse cell with an empty tail). Codex's CMAP correctly called this a **spec violation** (no-new-corruption-vector / fail-toward-hold), not an acceptable residual — architect-verified and agreed. **Fixed**: `isGhostCursorCell` now requires **positive ghost evidence** — ≥1 dim, non-whitespace/non-chrome tail cell — so an empty / whitespace-only tail stays `busy`; the real ghost is unaffected (its dim command body is 23 cells). Regression test added (inverse non-dim cursor, empty tail → `busy/user-text`). Separately, the finding's optional hardening — flag a sustained `user-text` hold whose counted-cell set is exactly {the cursor cell} as chrome in the classifier-stuck liveness net — is **deferred**: the exemption stops this drift class from producing a hold at all, so it no longer manifests; the net-level diagnostic would be belt-and-suspenders. +- **Silent-loss fix — benign partial-write residual.** If the text lands but the Enter is dropped mid-pace, the row is held `no-live-pty` while a draft sits in the composer. This never loses or double-delivers a message: a dead session is torn down and the agent-addressed row drains to its respawn; a recovered session shows a draft, so the render gate holds until the next clean prompt and delivers then. Recorded for completeness — no action needed. +- **Architect-identity SSOT is fail-closed, not fully authoritative**: the durable fix persists `command` on the session row + a legacy self-heal; a WELCOME-frame hydration (the fully-authoritative source) was deferred (needs a protocol change). +- **Migration tests use a faithful replica** of the production migration block, not the private `ensureGlobalDatabase` runner (repo precedent; source guards pin the real statements). Filed: extract `runGlobalMigrations(db)` for real migration tests. +- **`#1047` unbounded `partial` — CLOSED by round-2 (2026-08-06).** The whole-ring render that accepted an OOM residual on a pathological runaway is gone: the persistent bounded `SessionScreen` mirror classifies an O(viewport) screen and never allocates a whole-ring string, so the multi-hundred-MB-string OOM path no longer exists. (The "persistent xterm" this note deferred is exactly what round-2 built.) +- **agy `AGY_MARKER` (`/^> /`) is loose** and the interrupt-vs-mailbox-delivery cross-path is not fully serialized (architect-ratified as an accepted boundary; the convergence cleanup — route the mailbox write through `submitToSession` — is **filed as #1365**, out of scope for this PR). + +## Flaky Tests + +- **`render-gate.test.ts` perf assertion** — the seed-cap/whole-ring render-budget assertion flaked on loaded CI runners (best-of-5 125–142ms vs a 75ms local ceiling). Per architect direction, mitigated with a **CI-aware bound** (`process.env.CI ? 800 : 250` ms; earlier 500 for the seed-cap era) rather than a blanket skip, so the tight local steady-state signal survives while CI asserts only a catastrophic-regression ceiling. Documented; a deterministic op-count check is the intended replacement (Follow-up). +- **Whole-suite environmental flakiness** (not a single test): a `getcwd: cannot access parent directories` signature from a parallel-vitest-worker + git-subprocess temp-dir race (aggravated by 9+ concurrent sibling builders), and a build-race when `npm run build` (which `rm -rf`s `dist/`/`skeleton`) runs *concurrently* with vitest. Handled by not running the build concurrently with the suite and by retry; a direct suite run was always clean (0 failures). No individual test was skipped (none reproduced in isolation). +- **`session-manager.test.ts` auto-restart timing test** starved under full-suite parallelism (passed in isolation, ~472ms). No skip needed — it did not repeat. + +## Follow-up Items + +- ~~Resolve the T16-vs-1313 prompt-surface-manifest conflict with the 1280 owner (waleedkadous)~~ **DONE (2026-08-05):** resolved by reverting 1313's CLAUDE.md/AGENTS.md edits to `origin/main`'s tip — 1313 makes no net change to those prompt surfaces; Spec 1280 retains sole ownership of those files. T16 passes in the rebased/merged state (stays red on the un-rebased branch, which is 285 behind — its three-dot diff compares against the stale merge-base; clears with the maintainer rebase already needed for the CONFLICTING PR). +- Replace the render-gate perf wall-clock assertion with a deterministic op-count check. +- **#1361 (round-2 fast-follow):** close the adopt/reconnect torn-seed liveness gap — seed the gate mirror from the uncapped ≤8 MiB replay while the ring stays 1 MiB-capped (token-safe constant offset), or a repaint nudge on adopt for a total guarantee. Pre-existing + fail-safe today (holds, self-heals on repaint/viewer); tracked separately so round-2 stays scoped. +- Bound the VSCode escalation-toast `seen` Set (dedupe by mailboxId with eviction) — negligible today. +- Fuller close of the gate→write **input** race (a human keystroke between snapshot and write — `R7` staleness guard) and the input-echo-lag residual. +- Tighten `AGY_MARKER`; consider WELCOME-frame identity hydration; `#1047` persistent-xterm root cause. +- Extract `runGlobalMigrations(db)` so migration tests can drive the real production runner. +- **Coverage fast-follow (maintainer optional-2):** add a dedicated test for the wiring's owner-resolution (`escalateHeldToOwner`: architect-skip + spawning→`main`→first fallback + supersede-keyed enqueue) via the exported `makeDeliveryPorts` seam against a seeded global.db registry, and for `cleanupBuilder()`'s `dismissHeldForAgent` invocation. Today verified by inspection + the reused (tested) `resolveAgentInRegistry`; the round-3 drainer→port contract is covered. diff --git a/codev/specs/1313-afx-send-mailbox-first-delivery.md b/codev/specs/1313-afx-send-mailbox-first-delivery.md new file mode 100644 index 000000000..722c4c589 --- /dev/null +++ b/codev/specs/1313-afx-send-mailbox-first-delivery.md @@ -0,0 +1,265 @@ +--- +approved: 2026-08-01 +validated: [gemini, codex, claude] +--- + +# Specification: afx send — Mailbox-First Delivery (Never Force-Inject) + +## Metadata + +- **ID**: 1313 +- **Status**: specified +- **Created**: 2026-07-31 +- **Issue**: [cluesmith/codev#1313](https://github.com/cluesmith/codev/issues/1313) +- **Area**: Cross-cutting (`area/cross-cutting`) — the substance is the Tower send pipeline, but scope also includes the dashboard and VSCode sidebar indicators (decision 8), so per label policy the issue carries `area/cross-cutting` alone +- **Predecessors**: Issue #1265 (problem analysis); spike 1265 (`codev/spikes/1265-afx-send-line-occupancy.md`, branch `spike-1265`) — the empirical evidence base this spec draws on; Spec 403 (typing awareness), #450/#492 (composing flag added/removed), #584 (paced writes) + +## Clarifying Questions Asked + +All answers below are human (architect) decisions made 2026-07-31, during issue triage and spec review. + +- **Q: Should a message ever be force-delivered onto a busy line (today's 60s max-age path)?** + A: **No.** A busy line means a human is present at that terminal — escalate visibility through UI instead. There is no force path. +- **Q: Should the hooks-based delivery channel (Claude Code `Stop`/`UserPromptSubmit` hooks) be part of this project?** + A: No — removed from the issue. Injection onto a rendered-verified empty prompt is the only delivery mechanism in scope. +- **Q: How much held-message UI is in scope?** + A: Held-count indicator in the dashboard and VSCode sidebar, plus an `afx inbox`-style CLI to list/dismiss held messages. A rich message-center UI stays out of scope. +- **Q: What happens to messages addressed to a session with no live PTY?** + A: They persist as held rows and deliver when the agent respawns — the drop-with-WARN path is removed. +- **Q: Are agy (Antigravity) terminals supported delivery targets?** + A: **Yes — an agy gate profile is in scope and implementation blocks on it** (baked decision 12), alongside claude and codex. This requires new empirical measurement (the spike probed agy but did not derive a classifier profile for it). +- **Q: Does `afx send` gain a blocking `--wait` flag?** + A: No — the immediate `held` + row-id response is sufficient; senders should not block on human availability. +- **Q: How does the builder access the spike evidence (findings + POC harness), which lives only on branch `spike-1265`?** + A: **The builder fetches branch `spike-1265`.** The spike artifacts do not land on main as part of this project. + +## Problem Statement + +`afx send` models inter-agent messages as synthetic typing into the recipient's terminal. Today the deliver-vs-defer decision is a 3-second idle timer — a bad proxy for "is the input line empty?" A user who types a few words and pauses to think looks identical to a user at an empty prompt, so the message text plus an Enter keystroke land on top of their half-typed draft and submit the fused blob as one command. Reproduced in practice (issue #1265) and in the spike's harness against the real TUIs. + +Beyond the headline corruption, the current pipeline **loses messages silently**: held messages live only in memory and die with a Tower crash; graceful shutdown force-flushes them onto whatever is on the line; messages to sessions showing a menu, a trust dialog, or the builder launch-loop's relaunch/boot screens are eaten or stranded while the sender is told "delivered"; and two concurrent sends to the same session interleave into a single garbled submit. + +## Current State + +The pipeline is `afx send` → `POST /api/send` → `handleSend` (`tower-routes.ts`) → `SendBuffer` (`send-buffer.ts`) → `writeMessageToSession` (`message-write.ts`). Known failure classes, all empirically confirmed by the spike: + +1. **Timer-only deferral.** `shouldDefer` keys on `isUserIdle` (3s since last keystroke). A paused draft delivers immediately; the trailing `\r` submits draft+message fused. +2. **In-memory buffer.** Held messages die with a Tower crash; `SendBuffer.stop()` force-flushes on graceful shutdown; dead-session messages are discarded with a WARN; messages whose session is *unwritable* (shellper connection down) when the 60s max-age fires are dropped with an ERROR. +3. **Force delivery at max-age.** After 60s the buffer injects into any *writable* session regardless of line state (the unwritable case is the item-2 drop) — the destructive path this spec eliminates. +4. **No cross-writer serialization.** Two concurrent sends blob (`msg1msg2\r\r`, spike `w1a`); a send can land inside another write's text→Enter window. +5. **Mode blindness.** Delivery onto an open menu, model picker, trust dialog, or shell-mode composer misfires: Enter selects a menu item, confirms a filesystem-trust decision, or runs a shell command. The builder launch-loop wrapper's "Press Enter to relaunch" prompt consumes the message and relaunches the agent as a side effect; its crash-restart window strands the message as unsubmitted composer text. +6. **Bypass writers.** Cron messages write straight to the PTY with no idle check and no buffering, and log "delivered" unconditionally. + +Input-side signals cannot fix this alone: `afx attach` clients write to the shellper socket directly, invisible to Tower's input tracking, and sessions recovered after a Tower restart may carry drafts or menus Tower never saw. The only signal that sees all of this is the **rendered screen** — Tower already holds the output ring buffer that reproduces it. + +## Desired State + +A message given to `afx send` is **never silently lost and never corrupts anything** — every accepted message ends in an explicit, auditable outcome (delivered, superseded, or dismissed), never a silent drop: + +- At enqueue it is **persisted** before the sender gets a response. Tower crash, restart, or shutdown cannot lose it; shutdown never force-flushes it onto the line. +- It is **delivered only onto a prompt that is rendered-verifiably empty** — never onto a draft, a menu, a dialog, or a wrapper screen. (The rendered-screen gate is the sole authorization; apparent input-idleness never is.) Delivery happens at natural moments (at enqueue itself, after the user submits, on output quiescence, on a poll backstop), which for an idle agent at a clean prompt means near-immediate. No message text or Enter is ever written while the composer holds user input or a menu/dialog/wrapper screen is showing. +- If it cannot be delivered promptly, it stays **held and visible**: the sender knows (`held` response with a why-held reason), and the human can see held messages through UI and act. It is never force-injected, on any timeout — max-age becomes a visibility escalation. +- Messages to a respawned agent survive the respawn: rows address **agents, not PTYs**, so a new terminal for the same agent drains its predecessor's mail. +- Concurrent sends to one session serialize; no interleaving. +- Cron message delivery goes through the same mailbox + gate (it is a message writer, and today the most unguarded one); its run log records real outcomes. +- `afx send --interrupt` remains the explicit, deliberate bypass that skips holding — a sender action with unchanged semantics, outside the delivery guarantees above. +- The common case keeps today's feel: sending to an idle agent at an empty prompt delivers with no perceptible added delay. + +Corruption is eliminated **by construction** on every gated path, not by detect-and-repair: message bodies are only ever written to an empty verified prompt, so they cannot fuse with a draft, and nothing ever clears or restores user input. (`--interrupt` sits outside this guarantee by definition — its sender deliberately accepts that risk; residual gate risks are catalogued in Risks and Mitigation.) + +## Stakeholders + +- **Humans at terminals** (architect terminal especially): their in-progress drafts and menu interactions must never be corrupted, submitted, or cleared by an incoming message. +- **Agents** (builders, architects, cron tasks) as senders: need an honest response (`delivered` vs `held` + reason) instead of today's unconditional success; as recipients: need messages to arrive intact and actionable, including across respawns. +- **Workspace operators**: need held messages to be discoverable (indicator + `afx inbox`) and dismissible without reading Tower logs. +- **Technical team**: Codev maintainers own the Tower send pipeline and the per-app classifier profiles (a maintenance commitment across TUI version bumps). + +## Success Criteria + +- [ ] **The #1265 repro is dead**: type a draft in the architect terminal, pause >3s, have a builder `afx send` — the draft is untouched, the message is held, and it delivers cleanly after the draft is submitted. Same result when a menu or model picker is open instead of a draft. +- [ ] **Idle delivery is unchanged in feel**: send to an idle empty-prompt agent delivers immediately (gate adds ≤ ~50ms) and renders exactly as today. +- [ ] **No loss across Tower lifecycle**: messages held at Tower crash or shutdown are present and deliverable after restart; shutdown performs no force-flush. +- [ ] **Wrapper screens don't eat messages**: a send to a builder sitting at "Press Enter to relaunch" (or mid-crash-restart) is held, not consumed; it delivers after the agent is back at a clean prompt. +- [ ] **Concurrent sends serialize**: N parallel `afx send` calls to one target produce N cleanly separated submissions, in enqueue order, no interleaving. +- [ ] **Cron parity**: a cron message onto a busy/menu screen is held (and superseded by the next run of the same task, per decision 6), never blind-written; cron logs reflect real outcomes. +- [ ] **Escalation is visible**: `afx inbox` lists every held message from the moment it is held; a message held past the escalation age additionally emits the escalation broadcast and puts the dashboard/VSCode indicator into an attention state — all discoverable without reading Tower logs. +- [ ] **Held reasons are distinguishable**: the send response, `afx inbox`, and logs distinguish at minimum `busy` (draft/menu/mode), `no-profile` (unknown app), and `no-live-pty` holds. +- [ ] **No new corruption vector**: `--interrupt` and `noEnter` behave as documented; unknown-app targets receive nothing and hold visibly. +- [ ] **agy is a working target** (blocking): a send to a fresh agy terminal showing its trust dialog is held (never Enter-confirmed); after the human accepts trust and the prompt is idle, the message delivers cleanly. The agy profile measurement is a required implementation task — the project is not complete without this criterion. +- [ ] Unit tests cover the mailbox lifecycle (enqueue/hold/deliver/supersede/dismiss/restart-recovery) and gate classification against captured screen fixtures for claude, codex, and agy (idle, draft, menu, picker, trust dialog, wrapper, boot); e2e covers the repro scenario end-to-end. +- [ ] Documentation updated: `afx` command reference (send response vocabulary, `afx inbox`), inter-agent messaging section of CLAUDE.md/AGENTS.md, and the skeleton mirrors. + +## Constraints + +- **The rendered screen is the authority.** The gate classifies from the output ring buffer replayed through a headless terminal — the same data path the dashboard reconnect uses. Input-side heuristics (idle timer, submit detection) may *schedule* gate checks but never authorize a write by themselves. A wrong trigger costs a failed gate check (message stays held) — the safe direction. +- **Sessions are born dirty.** Fresh spawns show trust dialogs/onboarding; recovered sessions may carry unseen drafts or menus. A session becomes deliverable only after a gate check passes; there is no grandfathering. +- **Per-app classifier profiles are required data.** Claude Code, Codex, and agy get verified profiles (marker + composer region + text-intensity rule, per empirical measurement). Claude/codex behavior is already measured by the spike; **the agy profile requires new measurement** — the spike observed that agy's `> ` marker and normal-intensity hint text do not fit the claude/codex dim-placeholder rule, so agy needs its own classifier rule, derived with the spike's harness. agy's per-folder trust dialog is the canonical born-dirty case: it must classify not-clean (a blind Enter there would confirm a filesystem-trust decision). A session whose app has no profile, or whose screen never classifies clean, simply never receives injected messages — held + visible, with a diagnostic so a broken profile is discoverable rather than silent (liveness telemetry: repeated not-clean verdicts with recent output raise a loud log/broadcast). +- **Persistence lives in Tower's existing state store** (the user-global `global.db`); no new storage subsystem. +- **Backward compatibility**: the `/api/send` response stays additive — existing fields (`ok`, `terminalId`, …) keep their shape so older `afx` binaries continue to work; `held`/row-id/reason are new fields. A held outcome reports `ok: true` (the message was accepted and persisted) — an old binary thus sees exactly what it sees today for a deferred send, while new binaries read the real outcome from the new fields. The mailbox table is additive with migration-on-boot; no existing rows to migrate (the old buffer was in-memory — its contents were already lost at every restart, which is one of the bugs). +- **Existing send semantics carried over**: `noEnter` sends keep their staging behavior (text without submit); the one change is that, like every automated write, they now pass the clean gate first (staged text then occupies the composer, correctly holding followers). A gate-passed `noEnter` staging reports `delivered` — the write completed; submission was never part of a `noEnter` send. Message pacing (#584) is retained as-is for the write itself. Addressing/routing rules and the builder spoofing check are unchanged. + +## Assumptions + +- The output ring buffer (per #1047 sizing) is sufficient to reconstruct the current screen for classification — this is the same reconstruction the dashboard performs on reconnect, so any insufficiency is a pre-existing display bug, not a new risk class. +- The spike's measured per-app facts (markers, dim-placeholder rendering, wrapper screens, menu signatures for claude 2.1.x / codex 0.14x) remain representative; the spike harness re-verifies them on version bumps. +- The spike's POC harness and findings are accessible to the builder by fetching branch `spike-1265` (see Dependencies). +- `--interrupt` senders accept the documented risk (it interrupts the agent and bypasses holding) — that is its purpose. + +## Solution Approaches + +### Chosen: mailbox persistence + rendered-empty gate + write serialization + +Persist every message at enqueue; deliver only when a headless-terminal replay of the session's output ring classifies the screen as "clean prompt, empty composer"; serialize all automated writes per session. Never inject otherwise; escalate visibility instead. + +**Pros**: eliminates corruption by construction (nothing is ever written onto a non-empty screen); one gate covers drafts, menus, dialogs, wrapper states, attach-typed input, and post-restart unknowns; kills silent loss via persistence; small surface (~400–700 LOC). +**Cons**: delivery to a busy terminal waits for the human (by design, per the baked decision); per-app classifier profiles are a maintenance commitment. +**Complexity**: Medium. **Risk**: Low-Medium (classifier conservatism is fail-safe). + +### Rejected: input-side occupancy authority + busy-line delivery maneuvers (spike options A + B/C/H/I/J) + +Model the draft from keystrokes and let that model authorize delivery; when delivery must happen onto a busy line, clear/restore the draft (kill-yank, stash, byte-replay) with atomic write forms, a pre-Enter equality gate, and differential post-delivery verification. + +**Why rejected**: exists to serve force-delivery, which the human decision removed. ~2,400–2,800 LOC; per-app and version-fragile delivery forms; cannot restore multi-line drafts via kill-ring; input tracking is provably blind to `afx attach` and post-restart state. Archived as spike evidence. Note: spike option E's *flush-on-submit moment* is not rejected — it survives as one of the scheduling triggers in baked decision 5; what is rejected is treating any input-side signal as delivery **authority** (the gate always decides). + +### Rejected: agent-hooks side channel (deliver via Claude Code `Stop`/`UserPromptSubmit` hooks) + +**Why rejected**: explicitly cut by the human from issue scope. Claude-only (no codex/agy inbound equivalent), and cannot wake an idle agent — injection would still be needed for the idle case. + +### Rejected: notification-only mailbox (spike option L — never inject at all) + +**Why rejected**: defeats the purpose of `afx send` — the recipient agent must act on the message without a human relaying it. Gated injection onto a verified-empty prompt retains that while removing the corruption. + +## Non-Goals + +- **Any busy-line delivery maneuver.** No kill/yank, no `^S` stash, no byte-capture/replay, no draft clearing or restoring of any kind. (Spike options B, C, H, I — archived as evidence for a path not taken.) +- **Input-side draft modeling.** No DraftTracker, no cursor-aware line model, no per-keystroke occupancy state machine. Input events may serve as cheap *triggers* to run the gate; they are never the authority. +- **Delivery-form matrices.** No per-app atomic write forms or bracketed-paste framing work beyond what the existing write path already does; per-app knowledge is limited to gate *classifier profiles*. +- **Post-delivery verification epistemics.** No canonical-stream differential verify, no pre-Enter equality gate. With no force path and a gate before every write, the elaborate believed-sent analysis is unnecessary; residual wrapper-transition races are accepted and bounded by holding — the row stays held whenever the gate check fails or the PTY write itself errors (outcome semantics in Risks and Mitigation). +- **Hooks-based delivery channel** (per-app agent hooks reading a mailbox). Explicitly cut from the issue. +- **`afx attach` rerouting or shellper protocol changes** (observation frames, presence census). Attach-typed drafts are visible to the rendered gate, which is sufficient under a never-inject-on-non-empty policy. +- **The raw terminal write route** (`POST /api/terminals/:id/write`) and dashboard/VSCode interactive typing — these are terminal I/O primitives, not message delivery, and keep their current semantics. +- **Rich inbox UI.** The visibility surface in scope is the indicator + `afx inbox` CLI (baked decision 8); a full message-center UI is not. +- **Changing message formatting, addressing/routing rules, or the spoofing check.** + +## Baked Decisions + +1. **There is no force path.** No timeout, valve, or fallback ever writes a message onto a non-clean screen. Max-age is a *visibility* transition on a persisted row, not a delivery action. (The explicit `--interrupt` command is a sender action, not a timeout/valve/fallback — see decision 3.) +2. **Mailbox-first.** Persist at enqueue, before the send response. The in-memory `SendBuffer` queue collapses into the mailbox. Response vocabulary the sender can trust: `delivered` (gate passed, write completed) or `held` + row id + **why-held reason** — canonical reason tokens, used throughout this spec: `busy` (draft/menu/mode), `no-profile` (unknown app), `no-live-pty`. No more unconditional "delivered". (Exact response field names are settled in the plan; the spec-level constraints are the additive shape and `ok` semantics in Constraints.) +3. **Gate before every automated message write** — direct sends, drained holds, and cron alike. One code path. The sole exception is `afx send --interrupt`, the explicit, deliberate bypass: it interrupts the agent and writes without a gate check (unchanged semantics; the sender who invokes it accepts the risk). It is a command the sender chooses per message — not a timeout, valve, or fallback — so it does not weaken decision 1. +4. **Rows address agents** (workspace + agent identity), with terminal id as a hint, so respawned terminals drain predecessor mail. +5. **Delivery moments**: initial enqueue, user-submit trigger, output-quiescence trigger, and a poll backstop — each runs the gate; the gate decides. The enqueue-time check is the immediate path for an idle target at a clean prompt. Trigger heuristics stay simple deliberately (a missed trigger delays delivery to the next backstop poll; it can't corrupt anything). Automated writes serialize **per live PTY** (a message's text and its Enter are one unit); held rows drain in **enqueue order per agent** — the ordering senders observe. +6. **Cron messages** are enqueued like any send, with a per-task supersede key: a newer run's message replaces the older *held* row rather than queueing a backlog; the cron run log records the real outcome (`delivered`/`held`/`superseded`) instead of unconditional "delivered". **Supersede keys are cron-only in this project**: a non-cron send never supersedes another — each accepted send is an independent held row that resolves on its own (delivered or dismissed). Cron is the sole supplier of a supersede key (its per-task key). +7. **Held-message retention**: a *held* row is never TTL-dropped — it stays until delivered, superseded (senders with a supersede key — cron, per decision 6), or explicitly dismissed. **Dismissal is a human act via `afx inbox`** (CLI-only in this project, never automatic), is logged with row metadata (never the body), and is a soft state transition — the row is marked dismissed, not immediately deleted, so the outcome is auditable and queryable by row id. **Terminal rows** (delivered / superseded / dismissed) are pruned after a bounded retention window (default 30 days, configurable), so bodies do not accumulate indefinitely. +8. **Visibility surface** (resolved in spec review): a held-count indicator in the dashboard and the VSCode sidebar showing the count of **all** currently-held rows, plus an `afx inbox` CLI that lists **all** held messages (regardless of age) and can dismiss them. The dashboard/VSCode surfaces are read-only indicators — dismissal is CLI-only (decision 7). Backed by the `held` response, the Tower log, and **two distinct broadcast events**: a held-state-change broadcast (fires on hold/deliver/supersede/dismiss; keeps the indicator count live) and the escalation broadcast below (exact event names are plan-level). **Escalation age**: a held row crossing the escalation threshold (default 60s, matching today's max-age; configurable via `.codev/config.json`) emits the escalation broadcast and puts the indicator into an attention state — it never triggers delivery. **`afx inbox` scope and dismiss authorization**: `afx inbox` is workspace-scoped — it lists every currently-held row in the workspace, across all recipient agents, each with its row id and why-held reason (`busy`/`no-profile`/`no-live-pty`), and dismisses by row id. The **list is metadata-only** (no bodies); a specific message body is viewed on demand with **`afx inbox show `**, which fetches a single row — including its body — over the same local Tower connection (see Redaction under Security Considerations). `show` works on a row of any status, so a resolved (delivered/superseded/dismissed) row stays inspectable by id for audit until it is pruned. Dismissal carries the same workspace-human trust level as `afx send` itself (see Security Considerations): any workspace operator may dismiss any held row — there is no per-recipient ownership check. The **visual form** of the indicator's attention state (badge, color, count styling) is a plan-level UI decision; the spec-level requirement is only that a distinct, log-free attention state exists and clears when the row resolves. +9. **Dead-session messages persist** (resolved in spec review): no live PTY → held row (reason: no-live-pty), delivered when the agent respawns. The drop-with-WARN path is removed. Cron backlog stays bounded via supersede keys. +10. **Supported delivery targets are claude, codex, and agy** (resolved in spec review) — each with its own measured classifier profile. Everything else is unknown → defer-only, held + visible. +11. **No `--wait`** (resolved in spec review): the send response is immediate (`delivered` or `held`+id); no blocking mode in this project. +12. **Implementation blocks on the agy profile** (resolved in spec review): the measurement (derive agy's classifier rule with the spike harness) is a required implementation task, and the project is not complete until the agy success criterion passes. At runtime, an agy session still behaves fail-safe (held + visible) whenever its screen doesn't classify clean — blocking is a completion requirement, not a change to the gate's conservatism. + +## Open Questions + +### Critical (blocks progress) + +- None. All scope questions were resolved in spec review (see Clarifying Questions and Baked Decisions 8–12). + +### Important (affects design) + +- None. + +### Nice-to-Know (optimization) + +- [ ] Whether the VSCode indicator should also surface held messages in the existing Needs Attention view (plan-level UI placement decision). + +## Performance Requirements + +- **Gate cost**: the gate classifies the **seed-capped replay** — the same capped reconstruction the dashboard reconnect uses — so its input is bounded by the ring seed cap regardless of raw ring size. Bound: single classification ≤ ~50ms at inputs up to the cap (spike measured 2ms @ 13KB, 22ms @ 1MB = the cap; the 67ms @ 4MB measurement was an uncapped-ring lab case that the seed cap excludes by construction); run per delivery attempt, not per keystroke. +- **Idle-path latency**: no perceptible regression for send-to-idle-agent — ≤ ~50ms added end-to-end vs. today, **inclusive of** gate + enqueue persistence. This nests inside the gate's own ≤ ~50ms bound because that bound is the at-the-cap worst case: at realistic screen sizes the measured gate cost is single-digit milliseconds, leaving the end-to-end budget's headroom for persistence and serialization. +- **Enqueue latency**: mailbox persistence adds no perceptible latency to the `afx send` response (single local SQLite write). +- **Steady-state cost**: no per-keystroke work beyond what exists today; backstop polling only while messages are held for a session; zero background cost when the mailbox is empty. + +## Security Considerations + +- **Message bodies at rest**: mailbox rows persist user-authored message content in the user-global `global.db`. This inherits the store's existing access boundary (local, per-OS-user); no new network exposure. Retention follows baked decision 7: held rows persist until resolved (never TTL-dropped); terminal rows (delivered/superseded/dismissed) are pruned after the bounded retention window, so bodies do not accumulate indefinitely. +- **Redaction**: message bodies never appear in Tower logs, diagnostics, or telemetry — logging uses row ids and metadata only. UI surfaces that legitimately display bodies do so over the same local Tower connection that carries them today: **`afx inbox show `** for a specific row's body (the `afx inbox` *list* is metadata-only — no bodies), and the terminal stream itself (as mirrored by the dashboard/VSCode terminals) once a message is delivered. The dashboard/VSCode *indicator* remains count-only (decision 8). +- **Authorization unchanged**: the sender spoofing check (`tower-messages.ts`) and addressing rules are untouched; the mailbox introduces no new remote write path. `afx inbox` dismiss is a local-workspace human action, same trust level as `afx send` itself. +- **Injection safety**: the gate reduces the attack/accident surface — today a message can be blind-typed into a trust dialog or shell-mode prompt (where Enter *runs a command* or *confirms a filesystem-trust decision*); under this spec nothing is written to such screens. `--interrupt` remains a deliberate, explicitly-invoked bypass with unchanged semantics. + +## Test Scenarios + +### Functional + +1. Draft-in-progress send (the #1265 repro) — held, draft intact, delivered after submit. +2. Idle empty prompt — immediate delivery, correct rendering, `delivered` response. +3. Menu/picker/trust-dialog open — held; delivers after the screen returns to a clean prompt. +4. Builder wrapper states (relaunch prompt, crash-restart window) — held; delivers post-boot once clean. +5. Tower restart with held rows — rows survive; recovered session starts dirty; delivery only after a clean gate pass. +6. Respawned agent (new terminal id) — predecessor's held mail drains to the new terminal. +7. Concurrent sends (same target) — serialized, ordered, no blobbing. +8. Cron: busy target → held; next run supersedes; log shows outcomes. +9. `--interrupt` — bypasses holding, interrupts, delivers (unchanged). +10. `noEnter` — gate-checked, stages text, does not submit; a follow-up send holds behind the staged text. +11. Unknown app / no profile — never delivers, held + visible with reason `no-profile`, diagnostic raised. +12. Attach-typed draft (typed via `afx attach`, invisible to input tracking) — gate still holds delivery. +13. agy fresh spawn (trust dialog showing) — held; after trust is accepted and the prompt is idle, delivers; `afx inbox` shows the row while held. +14. Visibility surface — a held message appears in `afx inbox` (with its why-held reason) and in the indicator count immediately; crossing the escalation age emits the escalation broadcast and puts the indicator into an attention state; dismissing via `afx inbox` marks the row dismissed (not immediately deleted), removes it from the indicator count, and never delivers it. +15. Held-reason accuracy — busy vs. no-profile vs. no-live-pty holds are distinguishable in the send response, `afx inbox`, and logs. +16. Escalation-age threshold — a message held past the escalation age (default 60s) emits the escalation broadcast and moves the dashboard/VSCode indicator into its attention state, while **no delivery is triggered** by the threshold crossing itself; the row still delivers only on a later clean gate pass (and clears the attention state when it resolves). + +### Non-Functional + +1. Gate cost within the Performance Requirements bounds at realistic ring sizes; idle-case send latency within the idle-path budget (no perceptible regression). +2. Mailbox operations add no perceptible latency to the `afx send` response. +3. Message bodies never appear in Tower logs or diagnostics (assert on captured log output in tests). + +## Dependencies + +- **Internal systems**: the PTY output ring buffer (`pty-session.ts`, sizing per #1047) as the gate's data source; the `global.db` state store and its migration-on-boot pattern; the existing broadcast/WS event channel; the dashboard and VSCode sidebar for the indicator; the cron runner (`tower-cron.ts`) for the rerouted delivery path; the `afx` CLI for `inbox` and the extended send response. +- **Libraries**: a headless terminal emulator for screen reconstruction (`@xterm/headless` — already used by the spike harness; confirm/add as a production dependency of the Tower package). +- **Evidence base**: spike 1265's findings and POC harness live on branch `spike-1265`, **not on main** — the builder **fetches that branch** (human decision; the spike artifacts do not land on main as part of this project).

This is **pre-existing and unrelated to Spec 1313**: `pty-session.ts` is +byte-identical to main (untouched by phase_4); the base e2e used the same non-persistent `/bin/sh` path (only the args differ), +so it failed identically on main. The codebase already knows this trap — `terminal/shellper-main.ts` deliberately loads node-pty +via `createRequire` with an ESM→CJS-interop comment; `pty-session.ts` does not. +**Fix (in-scope, test-only):** register the e2e terminals via the **shellper (persistent) backend** (`persistent: true`) — the +same path Tower uses for real builders/architects, which spawns in its own process and is immune to the quirk. A shellper session +reports `command: ''` (pty-manager.createSessionRaw), which still resolves to `no-profile`, so the held-behavior assertion holds. +**Result: `send-integration.e2e.test.ts` 6/6 PASS** (incl. the new mailbox-first held HTTP contract: held+mailboxId+reason=no-profile). +Did NOT touch `pty-session.ts` (out of phase_4 scope; the createRequire fix for the non-persistent path is a separate concern — +noting for a possible follow-up issue). Diagnostics (dist patch, probe scripts) fully reverted; worktree clean. +Phase_4 evidence complete: build green, full unit green, deterministic #1265 repro green, subprocess e2e green. Committing, then +`porch done 1313` → 3-way review. + +### 2026-08-01 — Phase 4 review iter1 (Gemini APPROVE, Claude APPROVE, Codex REQUEST_CHANGES) → 3 fixes landed +Committed phase_4 (ff3b66eb) + thread (7988a06a); `porch done` → checks green → 3-way consult. Codex (HIGH) raised 3, all +verified against spec/plan and fixed: +1. **Prune retention default 7 → 30 (spec:147, plan:116).** Both Codex AND Claude flagged the 7-day default as a regression + (prunes audit rows 4× too early). Fix: `DEFAULT_PRUNE_RETENTION_DAYS = 30`; added `mailbox.retentionDays` to CodevConfig + + DEFAULT_CONFIG (30); `startMailboxDrainer` now reads it from the **user-global** `~/.codev/config.json` layer via + `loadConfig(homedir())` (the drainer is Tower-global — prunes every workspace's rows in global.db — so a per-workspace + config is the wrong source; malformed config falls back to 30). Test: default drainer keeps a 10-day row, prunes a 31-day one. +2. **project:agent cross-workspace offline hold (plan:264-269).** `resolveAgentInRegistry` returned NOT_FOUND (→404) for + `project:`, so cross-workspace sends lost the mailbox hold when the recipient was offline. Fix: resolve the target + workspace via `findWorkspaceByBasename` (the SAME mapping live `resolveTarget` uses) then hold against ITS registry. Boundary + documented: needs the target workspace active (its agent's PTY may be dead) — same limitation live resolution has. New + focused unit file `spec-1313-registry-resolve.test.ts` (7 cases: bare hold, tail-match, cross-ws hold, boundary NOT_FOUNDs). +3. **Subprocess #1265 full-cycle e2e (plan:313).** Plan wanted an e2e via vitest.e2e.config.ts doing draft→held(busy)→clear→ + deliver; the deterministic repro (send-mailbox-repro) does the full cycle but in the UNIT suite. Added the real subprocess + e2e: a dedicated ws with `.builder-start.sh`=claude (so the gate resolves the claude profile for a shellper session whose + command=''), an `stty raw -echo; cat` echo terminal whose composer bytes we drive via `/write`. De-risked with a throwaway + Node probe FIRST (proved held(busy) then delivered-via-broadcast) before writing the test — captured raw data beats guessing. + Result: send-integration.e2e **7/7** (draft→`held/busy`→clear→backstop redelivers `ship it` via source:'mailbox' broadcast). +Did NOT touch pty-session.ts (the node-pty quirk stays a documented pre-existing issue; the e2e uses the shellper path prod uses). +Verify: tsc clean; e2e 7/7; full unit suite re-running.

Wiring in pty-session.ts (emit signals) + the drainer (consume/coalesce). No new gate logic. + +### 2026-08-01 — Phase 5 IMPLEMENTED (commit 62855a88) — build+unit green +Design recon first (drainer, pty-session input/output signals, wiring, test harness). Key findings that shaped it: +submit is already detected at `tower-websocket.ts:96-97` (`stopComposing()` on `\r`/`\n`, Bugfix #450) — the human +terminal path; `onPtyData` already tracks `_lastDataAt` (Spec 467) + emits `'data'`. PtyManager is NOT an +EventEmitter (no session-created hook) and `PtySession.id` is public → chose a **module-singleton signal bus** +(`terminalDeliverySignals`) over per-session subscription: sessions emit `{kind, sessionId}`, wiring subscribes once +and reverse-maps id→agent lazily. This keeps pty-session ignorant of the mailbox layer (no import) and is consistent +with the single global drainer. Files: +- `pty-session.ts`: `terminalDeliverySignals` bus + `QUIESCENCE_DEBOUNCE_MS=500`. `stopComposing()`→emit `'submit'`; + self-rescheduling unref'd debounce keyed on `_lastDataAt`→emit `'quiescence'`, armed only when a subscriber exists + (zero-cost when drainer off), cleared in `cleanup()`. +- `mailbox-delivery.ts`: `MailboxDrainer.scheduleDrain(ws,agent)` — coalescing per-agent (burst→one pending promise→ + one gate check; slot released just before the pass so an in-pass trigger queues exactly one follow-up; KeyedSerializer + prevents overlap). Never rejects (logs, leaves for backstop). `recordStreak` extracted, shared with `tick`. +- `mailbox-wiring.ts`: `resolveAgentForSession` (inverse of resolveLiveSessionForAgent); subscribe/unsubscribe the bus + in start/stopMailboxDrainer (idempotent; detaches on stop so restarts don't leak listeners). +Triggers are schedulers never authority (spec Constraint): same gated `deliverAgentMailSerialized`; missed/spurious +trigger can't corrupt — gate decides, backstop is safety net. +Tests (+14): send-delivery (trigger-delivers-no-tick, spurious→held, burst coalesces to 1 gate check, held-then-clear, +pre-start no-op), pty-session-delivery-signals (submit/quiescence emit, re-arm mid-stream, lazy zero-cost), +spec-1313-resolve-agent-for-session (builder/architect/shell reverse-map + null cases). **Full unit 4123 pass / 48 +skip / 0 fail; tsc clean.** (Aside: session cwd drifted into packages/codev mid-run — a `cd x && …` re-`cd x` failed +once; harmless, re-ran from the right dir.)

Codex (HIGH) raised one real issue I'd +actually noted during design: the **submit trigger only fired on the tower-websocket path**, not the pty-manager +standalone terminal-server WS handler (`pty-manager.ts:306-318` did only `recordUserInput()`+`write()`, no +`stopComposing()`). Root cause = composing/submit detection **duplicated inline** (tower-websocket had it twice) → +a 2nd input path drifted. Gemini+Claude APPROVE, no issues (Claude: "No issues found"). +**Fixed by consolidation, not a 3rd copy** (SST — the lesson this bug proves): new `PtySession.handleUserInput(data)` += the one chokepoint (recordUserInput → composing/submit detect → write); both branches of BOTH WS handlers +(tower-websocket + pty-manager) now route through it. pty-manager path now fires `'submit'` on Enter like the Tower +path; neither can drift. Delivery still calls `write()` directly → never trips submit.

The plan's "workspace-**wide**" = all recipient agents *within one workspace*, not +Tower-wide; and line 241 shows Codex already settled this at spec review ("resolves Codex's scope question"). +No rebuttal — accepted + fixed. +**Fix (3 src + 2 test files):** +- `commands/inbox.ts`: `inboxList` defaults to the current workspace (`getConfig().workspaceRoot`, same + resolver `afx status` uses) when no `--workspace`; always sends `?workspace=`. `--workspace ` = a + different workspace. Updated interface/docstrings. +- `cli.ts`: `-w, --workspace` help "default: all workspaces" → "default: current workspace". +- `servers/tower-routes.ts` `handleInboxList`: **normalizes** the `?workspace=` param via + `normalizeWorkspacePath` (realpath) before `listHeld` — matches the enqueue-time normalized `workspace_path` + key (mirrors overview.ts); without it a symlinked root would miss its own rows. No-param→all retained as an + API convenience the CLI never triggers. +- `inbox-cli.test.ts`: mock `getConfig`; default query now asserts `?workspace=`; explicit + `--workspace` test unchanged. +- `inbox-routes.test.ts`: +1 normalization test (trailing-slash param still matches); scoping/redaction tests + unchanged. +No `--all`/admin mode (spec intends none; YAGNI).

Architect flagged the Claude consult +truncated on a session limit (empty output); re-ran it → APPROVE/HIGH, no issues. **Codex found a THIRD real +bug** (Gemini+Claude both missed it, both APPROVE): `POST /api/inbox/:id/dismiss` was matched by URL path only +(`tower-routes.ts:302`), and `handleInboxDismiss` took `_req` (unused) with **no method check** — so +`GET /api/inbox//dismiss` (any method) would dismiss mail. State mutation reachable by GET. Verified against +code — VALID (the GET *list* route is safe: it's in the method-keyed exact-match map; only the dynamic dismiss +route bypassed it). No dispute. +**Fix (1 src + 1 test):** +- `tower-routes.ts` `handleInboxDismiss`: `_req`→`req`; guard `if (req.method !== 'POST') → 405 + { error: 'Method not allowed' }` before any DB mutation — matches the cron action routes' convention + (`handleCronTaskAction` run/enable/disable, and :515/:582). Docstring notes the dispatch is method-agnostic. +- `inbox-routes.test.ts`: +1 regression test — `GET /api/inbox//dismiss` → 405, row still `held`, no + `overview-changed` broadcast. +Porch flow this round: `porch next` emitted a "write rebuttal (iter-3)" task → wrote +`1313-phase_7-iter3-rebuttals.md` (accept+fixed).

Next: commit fix → `porch done` (re-verify + mark rebuttal) → `porch next` +(iter-4 consult).

NOT running `porch done` on my own — porch says wait, and +the re-consult-vs-approve choice (with its consult cost) is the architect's.

CONFLICT: the standing project constraint (recorded +earlier) was "do NOT merge — maintainers merge", and the gate approval didn't explicitly lift it. Merging is +irreversible/outward-facing (lands on main, closes #1313), so NOT merging on an implicit signal.

Did NOT merge/force. Reported to architect. +Architect authorized me to merge #1330 (pr gate approved lifts the 'maintainers merge' constraint; builders merge +own PRs post-gate). Ran `porch done 1313` → porch now wants `porch gate 1313` (verify-approval). BUT `gh pr view` +shows mergeStateStatus=BLOCKED, mergeable=MERGEABLE. Two real blockers: + 1. **CI `Unit Tests` FAILED** = FLAKY PERF test `render-gate.test.ts:185` ("classifies over-cap snapshot + ≤~50ms budget") — asserted best-of-5 <75ms, got **125ms** on a loaded CI runner. Phase-2 timing test (comment + explicitly anticipates "slower/loaded CI"); my inbox-show delta touches NONE of the classifier path, and it + passed in earlier CI. → Classic CI-load timing flake, not a regression. Triggered `gh run rerun 30714025828 + --failed`. If it recurs → skip+annotate per flaky-test protocol + document in review Flaky Tests. + 2. **`reviewDecision=REVIEW_REQUIRED`** — main's branch protection requires a formal GitHub "Approve" review on + #1330. A builder CANNOT self-approve its own PR; this is SEPARATE from the Codev pr gate. Needs a maintainer's + GitHub review approval (or an admin merge). +Did NOT `--admin` force past a failed check + missing review (irreversible/outward-facing; architect said "regular +merge", not admin override). Reported both + the plan to the architect. Holding until rerun is green AND a maintainer +approves the GitHub review, then `gh pr merge 1330 --merge` → verify phase. Not polling. + +### 2026-08-01 — Blocker-1 (flaky CI perf test) MITIGATED: CI-aware bound (architect-directed). Local signal survives. +CI rerun 30714025828 re-failed on EXACTLY render-gate.test.ts:185 (best-of-5 125ms then 142ms vs 75ms ceiling; +everything else green 215/1/3). Architect PRE-AUTHORIZED the flaky-test-protocol mitigation for that one assertion, +then refined: **prefer a CI-aware guard over a blanket skip so LOCAL perf signal survives.** Implemented: +`const budgetMs = process.env.CI ? 500 : 75; expect(best).toBeLessThan(budgetMs)`. Tight ≤75ms local signal kept +(real steady-state check); CI asserts only the looser pre-tightening 500ms catastrophic-regression ceiling (3.5x the +worst-observed 142ms → won't re-flake; still 10x below an O(n²) blow-up at >1MB). Annotated with the spec's own +"slower/loaded CI" caveat + both reviewers flagging it. **Classifier code untouched — test-side bound only.** +Verified BOTH modes pass 28/28 (local 75ms; CI=true 500ms). Documented in review Flaky Tests + a Follow-up (swap the +wall-clock guard for a deterministic op-count check). Reverted my earlier interim `it.skip` (architect preferred the +CI-aware bound). Next: commit (render-gate.test.ts + review + thread, explicit staging) → push (re-triggers CI) → +report to architect. Blocker 2 (REVIEW_REQUIRED) stays PARKED — architect is the PR author (can't self-approve) + +no admin; needs a 2nd maintainer (e.g. waleedkadous) to Approve/admin-merge. Holding the merge + verify per directive. + +### 2026-08-01 — PUSHED 549f50cd + CI GREEN. Blocker 1 cleared. Only REVIEW_REQUIRED remains (parked). +New CI run 30714533930 on head 549f50cd: ALL 6 checks PASS, incl. 'Unit Tests' (2m1s) — the CI-aware perf bound +held (no re-flake). Blocker 1 (flaky perf test) CLEARED. `gh pr view 1330`: mergeStateStatus=BLOCKED but now for +ONE reason only — reviewDecision=REVIEW_REQUIRED (every status check green).

HOLDING merge + +verify per directive; will `gh pr merge 1330 --merge` → verify (agy trust-dialog smoke + #1265 repro) once the +review lands or the architect says go. Blocker 2 is external (maintainer-dependent), architect parked it → I end my +turn and stay addressable rather than long-poll for an open-ended review approval. Not merging, not --admin, not +self-approving, not running afx cleanup / closing #1313 (architect owns post-verify). + +### 2026-08-01 — Architect pinged (delivery smoke test on empty prompt). Feature worked; status reported. +Architect sent "hi" / "hey" / "testing while builder prompt is empty" — exercising Spec 1313's own mechanism +(mailbox-first delivery onto a render-gate-verified empty prompt). All three landed cleanly on my idle prompt = +the feature in action during verify. Re-checked PR #1330 fresh: OPEN, all 6 CI checks SUCCESS (green), but +isDraft=True AND reviewDecision=REVIEW_REQUIRED → mergeState UNKNOWN. So merge is gated by (1) draft status +(`gh pr ready 1330`) and (2) a maintainer GitHub Approve (I can't self-approve; no admin). Both are architect/ +maintainer actions; Blocker 2 was already parked. Still holding at verify-approval per strict mode + earlier +directive. Not merging, not un-drafting, not self-approving, not polling. Reported status to architect in-terminal. + +### 2026-08-01 — VERIFY-phase bug (architect-directed): `afx send architect` always no-profile. Fix implemented. +Architect found in live PR #1330 testing: sends to ANY architect (main + siblings, claude+codex) return +held(no-profile) and NEVER deliver; sends to builders deliver fine. My heads-up `afx send architect` ALSO got +held(no-profile) — the bug reproducing itself. Confirmed root cause in code (matches architect's diagnosis): + - `pty-manager.ts createSessionRaw` hardcoded `command: ''` for ALL shellper-backed sessions. + - `resolveProfileForSession` (mailbox-wiring.ts:147) then falls back to `harnessFromLaunchScript(cwd)` which reads + `.builder-start.sh` — ONLY builder worktrees have it. Architects run in the workspace root -> null -> no-profile, + permanently. Suite stayed green because gate/repro tests use a command-populated DOUBLE (never the real + createSessionRaw empty-command path). + +FINDING BEYOND THE DIAGNOSIS (flagged to architect via afx, held): architects have NO `.builder-start.sh` backstop, +so a creation-site-only fix makes them deliver until the FIRST Tower restart, then silently revert to no-profile — +the reconcile path (tower-terminals.ts:798) rebuilds architects from the DB, which stored no command. So I made +identity a single-source-of-truth on the session row + restart-safe. + +FIX (11 edits, tsc clean, new regression test 3/3 green): + 1. schema.ts + db/index.ts migration v16: `terminal_sessions.command TEXT` (mirrors label v11 / cwd v12). + 2. pty-manager.ts createSessionRaw: accept `command?`/`args?`, use in PtySessionConfig (default '' / []). + 3. tower-types.ts DbTerminalSession: +`command: string | null`. + 4. tower-terminals.ts saveTerminalSession: +`command` param + INSERT column/value. + 5.

Reconstruction paths restore `dbSession.command`: reconcile (798 + re-save 827), on-the-fly reconnect + (1012 + re-save 1050). + 7. tower-routes.ts create route (780): thread `command,args`; persist at both saves (800/823). Builders keep + the script backstop too. Shells resolve to no-profile correctly (not delivery targets). +NEW TEST: send-architect-identity.test.ts — drives delivery against a REAL createSessionRaw session (fake shellper, +real ring buffer, real PtySession.command) through the REAL resolveProfileForSession: (a) threaded command -> +delivered; (b) no command + no script -> no-profile held (locks the bug); (c) command round-trips terminal_sessions +-> reconstructed session resolves (restart-safe).

Verified the + ProbeResult plumbing (740/767) carries restartOptions. + 3. Migration blanket-swallowed ALL ALTER errors → a real failure would mark v16 done with no column, breaking + every future saveTerminalSession INSERT. Fixed: gate on `PRAGMA table_info` (add only if genuinely absent). + 4. `not.toBeNull()` can't tell claude from codex (shared marker/region) → exact `.app` assertions + a codex + delivery test (strict harness→profile mapping, constraint-10). + 5.

Claude APPROVE (verified against working tree: version +bump converges both paths, PRAGMA gate idempotent, self-heal real at all 4 sites, no cross-architect bleed). +Gemini APPROVE. Codex REQUEST_CHANGES on ONE verified new hole: + - The reconcile self-heal derives restartOptions.command from loadConfig()/'claude' but does NOT honor the + `TOWER_ARCHITECT_CMD` env override that FRESH-LAUNCH honors (tower-instances.ts:505/1034: env > config > + claude). So a legacy (command=NULL) architect launched via `TOWER_ARCHITECT_CMD=agy` with no matching config + would heal to 'claude' → agy marker mismatch → still never delivers. Same class as the round-1 legacy gap. + Verified in source before acting. + FIX: mirrored fresh-launch's exact precedence (env > config > 'claude') in BOTH reconcile derivations + (tower-terminals.ts ~654 + ~945). Also fixes a pre-existing divergence — auto-restart itself now relaunches + with the same command fresh-launch would use. +Also addressed Claude/Codex's shared "add a functional migration test" ask: added a `command column migration +(v16)` describe to spec-1313-migration.test.ts (repo's established pattern — build pre-v16 DB, run a faithful +PRAGMA-gated replica, assert: column added + v16 recorded + value round-trips; idempotent re-run; PRAGMA gate +skips ALTER on fresh-install shape; fresh GLOBAL_SCHEMA matches migrated shape). Plus Claude's comment nit +(tower-routes shell comment — a builder-worktree-cwd shell resolves via the launch-script fallback). +Nullish-'' edge (Claude): left `??` — precedence is correct (persisted = the running process's actual command; +restartOptions is the legacy fallback), and a persisted '' architect is unreachable. +RESULT: tsc clean; migration+identity files 16/16; full suite running.

Codex: TOWER_ARCHITECT_CMD finding RESOLVED, no new +inconsistency introduced — i.e. **the code fix is approved by all three reviewers now**. Codex's ONE remaining +blocker is test-methodology: the v16 migration test drives a faithful *replica* of the block, not the production +runner. Verified the facts before deciding: + - `ensureGlobalDatabase` is PRIVATE; the v1→vN chain is inline on the DB-init critical path. Driving it directly + needs an export/refactor of that path = high blast radius, out of scope for a delivery bugfix. + - Repo precedent is replica-based: v15, bugfix-826, pir-832 migration tests all replicate the block; state/ + spec-755 MOCK getGlobalDb. NO existing test drives the real runner. My v16 test matches this pattern (which + Claude explicitly endorsed as the model). + - Drift IS caught: source guards pin the exact production v16 statements (GLOBAL_CURRENT_VERSION=16, the ALTER, + the PRAGMA gate); the replica proves the logic; GLOBAL_SCHEMA convergence proves fresh-install correctness. +DECISION: rebut + defer, NOT refactor the DB-init path chasing a lone reviewer's methodology preference on +already-approved code (2 APPROVE + repo precedent). Filed "extract runGlobalMigrations(db) for real migration +tests" as a repo-wide follow-up in Technical Debt.

Ready for the architect's pr-gate decision. Committing the doc updates now; then reporting the decision +point to the architect. External gates unchanged + theirs: un-draft PR, maintainer GitHub approval (REVIEW_REQUIRED), +live afx-send-architect check after install. + +### 2026-08-02 — RESUMED. Architect directive: 3 render-gate false-`busy` blockers (do NOT approve verify gate). +Live testing of the built code (`pnpm -w run local-install`) found the render-gate reports `busy` for prompts that +are actually EMPTY+READY — 3 defects in `render-gate.ts`, all reproduced against REAL claude output (the classifier +was only ever validated against SYNTHESIZED `claude-idle` fixtures, so none were exercised). Report saved at +`codev/spir-1313-render-gate-bugs.md` (main checkout). Architect wants my fix PLAN (root-cause + approach + real-ring +testing) BEFORE coding; consult before big classifier changes. Verified all 3 against source: + - **D1** (field "monitor→busy"): a bg-task live-output panel displaces the composer's lower `─────` rule AND + `~/cwd` line → `findRegionEnd` finds no boundary → `endRow=lines.length` → scan runs into status chrome; that + chrome renders TRUECOLOR (isFgRGB), which the `isDim()`/one-palette skip doesn't catch → counted as user text. + - **D2** (field "empty held; ↑↓ delivers"): `capReplay` slices last 1MB of `getAll().join('\n')` mid-`partial` + (the unbounded alt-screen stream ring-buffer keeps WHOLE precisely so it isn't corrupted) → marker lost → + `no-composer-marker` busy. Existing >1MB test asserts only PERF on synthetic busy-tail filler. + - **D3**: idle false-busy is permanent — delivery path re-reads the same static ring; no repaint nudge (reconnect + clients get one via `resize()`→SIGWINCH, pty-session.ts:495 / shellper-process.ts:389). +PLAN written → `codev/projects/1313-.../1313-render-gate-fix-plan.md`. Approach: D1 = positively BOUND the composer +region (never fall through to lines.length; recognize the displaced panel boundary; truecolor-chrome recog as +defense-in-depth) — keeps fail direction SAFE (a draft's 1st cell is on the marker row, so bounded-region can't +false-clean). D2 = frame-aware cap (start render at most-recent full-repaint boundary; whole-ring backstop; pin the +boundary token from a REAL >1MB capture). D3 = throttled reconnect-style resize/SIGWINCH nudge for an idle +sustained-not-clean live PTY, then re-gate (re-prove, never force). Testing = capture REAL fixtures (bg-task panel + +>1MB) from my own live claude session, fixture regression tests → CLEAN, D2 marker-survives unit, D3 nudge unit, +live e2e re-verify. Sent plan summary + open questions to architect; NOT coding until approved. Strict-mode holds: +not approving verify gate, not merging, not editing status.yaml. + +### 2026-08-02 — PLAN APPROVED by architect (Q1-Q4 answered). CMAP on approach launched. Gemini in (REQUEST_CHANGES). +Architect approved + refined: D1 = P2 (footer/top-rule boundary) PRIMARY, MAX_COMPOSER_ROWS safety-cap ONLY; +MUST-test collision (draft+panel→BUSY, empty+panel→CLEAN). D2 = render-whole-ring baseline within a generous +ceiling, frame-aware slice only as tearing-safe fallback. D3 = transient ±1-row resize nudge (same-dims is a +CONFIRMED no-op per ring-buffer.ts:41), idle+throttled, re-prove only. Q4 = gzip fixture ~1.1MB. Also capture codex +(+agy) bg-panel; architect runs live e2e on main (I can't restart shared Tower from worktree) — I build fixtures + +unit/integration + hand them the checklist.

Probed self-capture: claude/codex/agy binaries + node-pty +ALL present (self-capture harness is feasible as a fallback). Requested the architect's raw bug captures (delivered) +to build fixtures against the EXACT rings vs a re-derived state. +GEMINI CMAP = REQUEST_CHANGES, 3 substantive points I'm adopting/surfacing: + - D1: my proposed "count only default-fg normal" INVERSION is UNSAFE (colored user input — syntax hl, /help blue, + red validation, accepted autocomplete — would be ignored → userCells=0 → FALSE-CLEAN/corruption). KEEP the + fail-safe BLOCKLIST (skip known chrome); the panel IS scanned (sits above the footer boundary) so explicitly + skip its truecolor/palette chrome. Aligns with the gate's existing fail-safe design. ADOPTING. + - D2: don't require a full-repaint boundary (brittle); just avoid slicing MID-ESCAPE-SEQUENCE (scan back to last + \x1b). Tearing plain text = safe false-busy; breaking the parser mid-seq = lost marker. Ceiling 8MB (~130ms) not + 16MB (250ms every 1.5s too much CPU). ADOPTING. + - D3: RECOMMENDS ABANDONING — ±1-row resize can reflow-LOSE a draft (idle session w/ an abandoned draft) → + FALSE-CLEAN. Contradicts architect's explicit directive. Will surface to architect w/ a narrower option: scope + the nudge to `no-composer-marker` ONLY (no marker ⇒ no draft to lose ⇒ no reflow-corruption), never to + `user-text` busy.

Then ARCHITECT CAP-SWEEP REFRAME (captures delivered). +CODEX (converges w/ Gemini: reject inversion) ADDS: MAX_COMPOSER_ROWS must NOT "scan capped rows then CLEAN" — +cap exhaustion w/o a trusted boundary → BUSY/hold (a draft can have arbitrary leading blanks). Count ALL unexplained +cells; skip truecolor only when STRUCTURALLY chrome. Content end-patterns can match DRAFT content (pre-existing). +D2: deterministic SIZE ceiling not time; JS .length is UTF-16 code units NOT bytes; lone 2J/H isn't a full frame. +D3: KEEP as recovery (vs Gemini abandon) done right — "no OUTPUT" ≠ "no INPUT" (track input-gen), re-gate only after +OBSERVED post-restore output+quiescence. NEW FALSE-CLEAN: gate→write INPUT race (human keystroke between snapshot & +write lands msg on a nascent draft) — "corruption eliminated by construction" is stronger than the code supports. +CLAUDE (instrumented the REAL fixtures) = the standout: PROVED the inversion false-cleans agy-trust (0 default-fg +cells → auto-confirms filesystem-trust dialog; breaks existing test :139-148). R2 (DOMINATES): D1 root cause is +findRegionEnd→lines.length; fix = "no region-end boundary ⇒ BUSY" + add footer/progress/cwd boundary patterns — +verified preserves ALL 12 fixtures, ~5-line diff, closes a LATENT false-clean. R3: DROP MAX_COMPOSER_ROWS (narrowing +always fails toward CLEAN). R4: test if D1 is D2-in-disguise (torn replay, not a real layout). R5: track repaint +offset at PUSH time + verdict caching on currentSeq+partialBytes (kills per-1.5s-tick re-render). R6: resize is +SHARED viewer state — skip nudge when a viewer attached, scope to `busy`, re-read restore dims, absolute throttle +floor, sequence after D2. R7: no staleness check — "ring grew in last ~200ms ⇒ hold" (cheapest remaining safety). +R8: AGY_MARKER /^> / too loose. + +**ARCHITECT CAP-SWEEP (supersedes part of D1/D2 framing) — CONFIRMS Claude R4:** ran a cap-sweep on real captures; +the false-busy is a **capReplay ARTIFACT**. WHOLE-ring render → ALL captures CLEAN (incl. the bg-task/monitor ring); +verdict flips purely with slice size (bgtask 2.79MB: BUSY≤2MB, CLEAN≥2.5MB; bigring 2.99MB: CLEAN only WHOLE — setup +in oldest ~0.5MB). So "D1" (panel displaces rule → truecolor counted) is a DOWNSTREAM SYMPTOM of the slice, NOT a +faithful claude layout. REFRAME: **D2 (render whole ring, don't slice) = THE ROOT FIX** (fixes BOTH field bugs) — +primary; **D1 = minimal DEFENSE-IN-DEPTH** (mid-repaint/partial guards), don't over-invest. DROP frame-aware-boundary +for correctness (no full-repaint boundary exists for an alt-screen app): remove/greatly-raise RING_SEED_MAX_BYTES, +keep only a generous absolute ceiling as #1047 backstop, retune perf test.

Suite 4266 GREEN. +The architect-directed third pass verified the round-2 fixes (`5bc7d56e`). ALL THREE returned REQUEST_CHANGES — +converging on two real defects in the round-2 code + smaller items. All fixed (mailbox-delivery.ts + tower-routes.ts): + 1. **Memo invalidation sat BELOW the markDelivered guard** (Codex HIGH, Claude blocker): a row dismissed/superseded + DURING the paced write (bytes already out) early-returns without `memo.delete` → follow-up memo-hits the stale + CLEAN and writes onto the un-echoed line. FIX: moved `memo?.delete(cacheKey)` to right AFTER writeMessage, above + the guard (the write is what stales the verdict, regardless of the row's transition). + test (dismiss mid-write). + 2. **Generation TOCTOU** (ALL THREE): the `gen` check precedes the await in BOTH tick + scheduleDrain, but + recordStreak/updateBackoff FOLLOW it → an in-flight pass resuming after stop()/start() re-seeds the freshly-cleared + streak/backoff maps. FIX: post-await `if (generation !== gen) return` before the mutations in both; scheduleDrain + also guards its slot delete with `=== run` + checks gen BEFORE the delete (Codex — can't drop a new gen's slot). + + 2 deferred-classifier tests (tick + scheduleDrain across stop/start). + 3. **Cooldown stale classifier-stuck alarm** (Codex MED, Claude LOW): skipped-tick recordStreak re-feeds the CACHED + no-region-end; a ring that cleared mid-cooldown (no fast trigger) still crosses threshold on the stale detail → + spurious onLiveness. FIX: force ONE fresh classify on the exact tick the streak would cross the threshold on a + classifier-stuck reason (escalation fires once → one render at the crossing; cleared→delivers, stuck→confirmed). +test. +Smaller (same commit): tick had NO catch → a backstop throw = unhandledRejection → process.exit(1) = Tower death +(Claude MED; the round-2 stop() comment wrongly called it "harmless") — wrapped per-agent work + escalate/prune in +try/catch, corrected the comment.

Gemini APPROVE; Codex + Claude 1 finding each. HOLDING on an architect decision. +Round 4 reviewed the pushed/committed 9ba8b5b7 (correct code). Verdicts: + • Gemini APPROVE — all six round-3 fixes verified, no new regressions. "Ship it." + • Codex REQUEST_CHANGES (1): Fix-1 `memo?.delete` is skipped if `writeMessage` REJECTS. Adjudicated against the live + binding: `writeMessagePaced` (mailbox-wiring.ts:185) runs writeMessageToSession sync (first write sync, rest via + setTimeout) then returns `new Promise(resolve=>setTimeout(resolve,doneMs))` — it NEVER rejects after a partial + write; only the sync first-write throw rejects it = ZERO bytes out = cached CLEAN still valid. So Codex's scenario + is NOT reachable via today's binding (Claude's analysis) — BUT it's real at the PORT CONTRACT (`void|Promise`) + and this module is written against the port, not the binding. Both reviewers call the `try{await}finally{memo.delete}` + harmless → applying it as contract-level defense + a rejecting-write test. + • Claude REQUEST_CHANGES (test-only, 1): the round-3 `scheduleDrain` generation test is VACUOUS — the drain body is a + microtask that never parks at the classify await before stop()/release() run sync, so it bails at the pre-existing + top-of-cb gen check (never reaches the post-await guard). Claude proved it (reverting the whole fix keeps suite green) + AND proved the runtime fix is load-bearing via a probe. 1-line fix: drain ~20 microtasks to actually park. + revert-check. + Both findings = completeness/coverage, NOT regressions in the round-3 code. All 6 runtime fixes verified correct + (Gemini+Claude fully; Codex 5/6 + the contract edge). Claude minor TD note: a forced classify that returns `busy` lets + the streak advance past 10 so escalation can't re-fire that episode — accuracy-vs-eager-alarm, escalateOverdue backstops. + +⚠️ WORKING-TREE ANOMALY / DECISION PENDING: mailbox-delivery.ts has Fix 6 (round-3 cooldown fresh-classify) replaced with +`if (true) {` in the WORKING TREE (uncommitted; not mine). It reverts the force-classify-at-threshold, FAILS the cooldown +test (functionally identical to the `false &&` revert I already showed fails `expected 3 to be 4`), and contradicts its +comment. PR #1330 @ 9ba8b5b7 + all round-4 reviewers have the CORRECT code. Per guidance I have NOT reverted the edit. +Sent the decision to the architect via `afx send architect` (DELIVERED): (A) restore Fix 6 [recommended — all 3 verified +it correct; closes a visibility-only false-escalation] or (B) drop it [I finalize the revert: kill dead comment, drop/adjust +the cooldown test, record the tradeoff]. HOLDING the two round-4 fixes + the commit until the architect steers. +Strict mode: NOT approving any gate, NOT merging. + +### 2026-08-03 — CORRECTION + round-4 fixes applied. Suite 4267 GREEN. Ready to push #1330. +CORRECTION to the prior entry's ⚠️ anomaly: the architect verified (and I re-confirmed against ground truth) that the +`if (true)` edit is NOT on disk — `git diff HEAD -- mailbox-delivery.ts` is EMPTY (byte-identical to committed 9ba8b5b7), +git status shows ONLY the thread modified, and lines 624/627 read `const wouldCrossOnStale =` / `if (!wouldCrossOnStale) {`. +Fix 6 is PRESENT and CORRECT; there was nothing to restore. Whatever I saw earlier via git diff was a transient/phantom +that resolved back to HEAD before I acted — I did NOT revert or restore anything in mailbox-delivery.ts. Architect +directed: proceed with ONLY the two round-4 completeness fixes. Done: + • Fix A (Codex, rejection-safety): wrapped the delivery write in `try{ await writeMessage }finally{ memo?.delete }` so + the memo is invalidated on a REJECTION too, not only a clean return (round 3 had moved the delete above the + markDelivered guard but a throw would skip it). Adjudicated: not reachable via today's `writeMessagePaced` binding + (rejects only on the sync first write = 0 bytes) but real at the port contract (`void|Promise`); module defends + the port, not the binding. + rejecting-write regression test. + • Fix B (Claude, test-only): the scheduleDrain generation test was VACUOUS — its drain body is a microtask that never + parked at the classify await before stop() ran. Added `for(i<20) await Promise.resolve()` to actually park before + stop(). Runtime fix was already correct (Claude proved via probe); only the test needed to reach it. +REVERT-CHECKED both: rejecting-write test fails on reverting the finally (classifyCalls 2→1); scheduleDrain gen test now +fails on reverting the post-await guard (streaks 0→1) — previously green even fully reverted (that was the vacuity). +Cooldown test GREEN (classifyCalls=4).

Since 6a50091a's ^2 IS my rebase base, everything the +merge pulled is already in the base — the ONLY real artifacts are where my wholesale `checkout --theirs` discarded base content: +**tower-routes.ts** (fixed: restored to backup HEAD's version = escape wrapped + import w/ comment; diff vs backup now only the +--delay graft) and tower-routes.test.ts (took my version; re-covering delay at route level).

Staying at pr gate. + +### 2026-08-06 — RESUMED: architect 1307 correction; --delay contract verified + tested; 2 failures fixed; suite GREEN +Architect RETRACTED the earlier "spec 1307 is mislabeled / don't read it" guidance: spec 1307 IS /arch-save but was DESCOPED by +the owner to exactly ONE mechanism — `afx send --delay`. So `--delay` is a genuine 1307 deliverable, the commit tags are correct, +and `codev/specs/1307-arch-save-packaged-save-clear-.md` on origin/main is the AUTHORITATIVE contract. Read it; verified my +mailbox re-homing preserves all 5 load-bearing points: +- **(1) ORDERING (load-bearing)** — a delayed send must never overtake a message already QUEUED for the session (the /clear-no-delay + then /arch-init-delay case; /clear must land first). HOLDS by construction: the delayed row is enqueued ONLY at fire-time (timer + callback → `enqueueMailbox`), so its `created_at` is strictly later than any already-held row; the drain (`findHeldForAgent`) + returns oldest-first (`created_at ASC`) and delivers held[0], one per clean gate pass, serialized per-agent (KeyedSerializer) with + an atomic claim. So /clear (older) always drains before /arch-init (younger). 1307 got this from SendBuffer FIFO; we get it from + the mailbox oldest-first drain. +- **(2) COMPOSITION** — `--delay` composes with --raw/--file/--no-enter/--all/--interrupt + every addressing form; undelayed path + unchanged (delay branch gated on `deliverAfter !== undefined`). Handled in the handleSend graft (formattedMessage honors raw, + noEnter threaded, interrupt sub-branch keeps the gate-bypass, resolveTarget owns addressing/spoofing). +- **(3) NOT request-order across differing delays** — `--delay 30` then `--delay 5` delivers 5s first. Not FIFO. Covered by the + "delivers by DUE time" test. +- **(4) Invalid delays rejected at the CLI boundary** — validateDelaySeconds (also re-validated at the public /api/send route). +- **(5) DURABILITY** — pre-due delayed sends live ONLY in the in-memory timer registry (dropped on Tower restart, per 1307); the + durable mailbox row is created by the fire-time callback, never before. A due-then-held send becomes a durable held row (strictly + stronger than 1307's always-drop; not-yet-due still drops). + +**Fixed the 2 known reconciliation failures:** +1. `hot-tier.test.ts` (Spec 987 cap): arch-critical.md UNION was 11 facts (cap 10). Demoted the "Governance docs are two-tier + (Spec 987)" META-fact to cold — its full treatment already lives in arch.md §Spec 987 (2058-2066), and the hot file's own header + already states the cap/displacement discipline, so zero info lost. Kept both new behavior-changers hot (#1189 server/client + + 1313 mailbox-first). Now 10 facts / 32 lines. Used the update-arch-docs skill (diff-mode). CLAUDE.md/AGENTS.md untouched (1280). +2. `send.test.ts` "buffered send as queued": the SendBuffer `deferred`/"queued" bucket is dead; send.ts reports `held` via + logger.info now. Rewrote the test to the mailbox `held` model (asserts held-not-delivered). + +**Added the ordering regression guard** (the mailbox-model replacement for the removed SendBuffer ordering test): new nested test +in `send-delivery.test.ts` — "delayed sends never overtake already-queued mail (Spec 1307 ordering)". Drives the REAL chain: +real `scheduleDelayedSend` timer (fake clock) → fire-time `mailbox.enqueue` → real `deliverAgentMail` drain → asserts /clear +drains first, /arch-init second, and that /arch-init's row doesn't exist until the timer fires (created_at strictly later). Left a +pointer to it in spec-1307-send-delay.test.ts's FIFO section. + +**Reconciliation-artifact cleanup:** delayed-send.ts (the survivor file) carried present-tense refs to DELETED code — `SendBuffer` +and `deliverOrBuffer` (main's function that never existed in my tree). Rewrote those doc-comments to the mailbox path; also fixed +the 4 `deliverOrBuffer` refs in spec-1307-send-delay.test.ts and its stale pointer to a non-existent tower-routes interleave test +(now points to the real `deliverAgentMailSerialized` serialization test). `grep deliverOrBuffer` = NONE. Every other file already +framed SendBuffer as "retired" correctly. + +**Green:** full build exit 0; full unit suite **4535 passed / 0 failed / 48 skipped** (was 4532/2/48 pre-fix).

STAYING at pr gate — no self-approve, no merge, no status.yaml edits. + +### 2026-08-06 — PR-ITER (architect live-test): render-gate ghost-cursor false-`busy` fixed +Architect live-tested the installed build and found `afx send`s to an **idle** agent stranding `held(busy)` while the +composer was empty (held row a21b6c64 → main). Root cause (architect byte-level verified, handed off in +`codev/spir-1313-captures/findings-ghost-cursor-false-busy.md` + a captured ring): **claude 2.1.220 paints a +suggested-command ghost** into the idle composer when its own last reply mentioned a runnable command. The ghost's first +char doubles as the software block cursor — **SGR-7 inverse at NORMAL intensity** while the rest is SGR-2 dim +(`❯ ␛[7ma␛[27m␛[2mfx cleanup…␛[22m`). The dim rule skipped the ghost body but **counted the lone inverse cursor cell** +→ `user-text`/`busy` FOREVER on an idle terminal. Fail-safe → fail-FORWARD for an idle recipient (the exact agent +`afx send` exists to wake). + +**Diagnosis first (before choosing a fix).** Loaded the fixture through the worktree gate: cursor parked at (58,2) on +`"a"` inv=1 dim=0 — the SOLE counted cell; tail `fx cleanup -p task-VdfD` all dim. Pre-fix verdict via installed dist: +`{clean:false,reason:busy,detail:user-text}`. Then rendered the **real-draft** fixture (`claude-draft.busy`) to settle +A-vs-C: claude renders the inverse block cursor on the **trailing whitespace** past a real draft (skipped as whitespace) +and **never inverse-renders typed chars** (all 21 draft cells inv=0). So the inverse attribute on a *non-whitespace* +cursor cell with a dim tail is a precise ghost discriminator → chose **Option C (ghost-signature, inverse-gated)** over A +(unconditional cursor-skip): C has ~nil false-clean surface on real drafts, A doesn't. + +**Fix** (`render-gate.ts`): `isGhostCursorCell` exempts exactly the cell at the headless cursor position that is +**inverse + non-dim + has a dim/empty tail on its row**.

The branch carries #1205's +RingBuffer partial cap (2 MiB ceiling, `trimPartial` halves to ~1 MiB).
