feat(gate): add the live route surface as a third source for CONTRACT-001 - #83
Merged
Conversation
…-001 WAVE-GA-VERDICT false-green #11. published-contract-drift compares repo-declared against gateway-published. Neither side is the live route table, so a route that is live and absent from BOTH documents is invisible to it by construction — the gate can be green forever while production serves undocumented, billable API. Measured against production 2026-09-05, 232 candidate routes probed: 12 routes live and absent from BOTH artifacts, 10 of them answering 402 — live, mapped and PRICED. 0 findings from the same input under the two-artifact comparison. The probe semantics are the load-bearing part. On this gateway an unmapped path answers 403 with error.code ROUTE_NOT_MAPPED; anything else, INCLUDING 402, means the route exists. A 402 is the strongest evidence of presence available — mapped and priced — so reading a paywall as an absence would blind the gate to exactly the routes that charge customers. Probes are unauthenticated GETs at concurrency 4; no credential is sent and a 402 is returned before any work, so they are free. Enumeration unions five public sources and probes every candidate. The gateway's own capability index is an advisory enumerator, not an authority: it is derived from the route->scope map, so a PRE-AUTH route cannot appear in it. That is a class, not an oversight — /v1/samples/clips answers 200 and is absent from openapi.yaml, from the published contract, and from that index. It is carried in live-route-seeds.json so it can be a candidate at all. Two false positives from an earlier draft were removed by narrowing what the evidence supports, not by suppressing findings: - A GET probe cannot judge a POST-only declaration. /v1/agent/auth/{device,token} are POST-only and answer ROUTE_NOT_MAPPED to a GET. Now INDETERMINATE and surfaced — unknown is not a pass, and it is not a finding either. - /robots.txt, /health and friends are outside the spec's own servers[0] base. Scoped out by that base, so every /v1 route stays in scope; a control test proves an undeclared /v1 route is still caught. Tests: 20 new, offline, injected fetch. Positive controls throughout so the gate discriminates rather than blanket-failing. Mutation proof: reading 402 as absence fails 2 tests; removing the live-undeclared direction fails 6, including one that asserts the two-artifact comparison finds nothing on input the probe catches. Full .github/scripts suite 59/59. The diff artifact is uploaded per run, never committed: it enumerates the live route surface and this repository is public.

Re-trigger cubic
…rd source
Every finding was re-verified against current code before being fixed; none
dismissed. All are duplicates or independent reports of the same set of real
defects from coderabbitai and cubic-dev-ai across the three-way comparison.
- basePath threw on a relative servers[0].url (e.g. "/v1") and silently
collapsed to base "", dropping /v1 off every candidate and probed path.
Resolved against a dummy origin instead.
- classifyProbe treated ANY status carrying error.code === ROUTE_NOT_MAPPED as
ABSENT. The documented contract requires HTTP 403 specifically; a non-403
gateway error with the same code could hide a real live-route finding. Also
added: a 3xx (redirect: manual leaves a non-JSON body) fell through to
MAPPED, which is wrong in both directions since a redirect proves nothing
about route existence. Both now require the exact contract.
- The two-segment fallback in compareAgainstLive covered ANY probed path
sharing a declared prefix, not just the product-root case it was built for
-- so an undeclared route nested under a declared product segment (e.g.
/v1/clips/export-all under declared /v1/clips) was invisible, the exact
false-green class this gate exists to close. Restricted the fallback to
paths that ARE their own two-segment key.
- Operations with their own OpenAPI servers override (the Realtime API,
documented under this document's base but served at realtime.wave.online)
were probed and compared as if served at api.wave.online/v1 -- MEASURED:
this produced a false declared-not-live finding for /v1/realtime/connect.
candidatePaths and compareAgainstLive now exclude any path where every
operation carries its own servers override.
- decideExit: a run where every probe came back 5xx/timeout/transport-failure
produced zero findings and exited OK, so a gateway outage both read as "no
drift" and would have closed a real open tracking issue. Probe-level
indeterminates now force EXIT_UNKNOWN; method-based indeterminates (a
POST-only route probed with GET) remain excluded, since those are expected.
- enumeratorShapeError: a 200 with valid JSON in an unexpected shape was read
as "this enumerator has zero routes" rather than "this enumerator could not
be read". MEASURED: the real capability index is a bare JSON array (valid,
since candidatePaths reads it via Object.values) while the published
contract and scope catalog are objects -- shape checked per-source rather
than requiring one universal shape.
- parseArgs: --out <path> with the default spec treated the output filename
as the spec and exited UNKNOWN before ever probing. Extracted into its own
testable function and fixed to skip the value --out consumes.
- Workflow: both npm installs now pass --ignore-scripts (lifecycle scripts on
a job that later holds an issues:write token). Removed the registry-reaching
install from the offline unit job entirely (the test imports no js-yaml).
workflow_dispatch on the drift job is now restricted to the default branch,
since it files/closes one repo-wide tracking issue. gh issue list --limit
100 was replaced with gh search issues (still exact-title filtered in jq)
so the tracking issue is found regardless of how many newer open issues
exist.
New regression tests split into live-route-drift-regressions.test.mjs (a real
seam: this feature's original suite vs. regressions on findings fixed after
the fact) so neither test file grows unbounded.
Measured:
node --test .github/scripts/*.test.mjs -> 66/66 pass
node .github/scripts/assert-refs.mjs openapi.yaml -> 710 refs resolve
npx @redocly/cli@2.40.0 lint openapi.yaml -> 0 errors, 55 warnings (baseline)
actionlint .github/workflows/live-route-drift.yml -> clean
zizmor .github/workflows/live-route-drift.yml -> only the pre-existing adhoc-packages advisory
node .github/scripts/live-route-drift.mjs openapi.yaml --out ... -> runs clean against the live
gateway, 0 declared-not-live false positives from the realtime.wave.online operations

What this fixes
WAVE-GA-VERDICT false-green #11.
published-contract-driftis green, and it is structurally incapable of seeing the thing CONTRACT-001 actually cares about.By its own header it compares repo-declared (
openapi.yaml) against gateway-published (https://api.wave.online/openapi.json). Neither side is the live route table. Both are documents we write, and both can be wrong in the same direction at the same time. A route that is live in production and absent from BOTH is invisible to that gate by construction — it can serve traffic, and be billable, while the check stays green forever. Green there means "the two documents agree", not "the documents describe reality".A gate must be able to observe the thing it gates. This adds the third source: the live surface itself.
What I measured
232 candidate routes probed against production on 2026-09-05:
That last row is the finding. Ten live, priced, billable routes that neither document describes, and the existing gate reports none of them — not because it is broken, but because it is looking at the wrong two things.
Positive control
A zero with no control is not a measurement, so every probe result was paired with one.
/v1/clipsand/v1/renderare present in all three sources and answer 402; a path that does not exist answers 403ROUTE_NOT_MAPPED. The method discriminates rather than reporting everything as missing.One premise from the verdict was wrong, and I am reporting it as wrong
The verdict named
/v1/clipsas live-and-absent-from-both. It is not. It is declared inopenapi.yaml(as/clips, under the/v1server base), it is in the published contract, and it is in the gateway's capability index — present in all three. It served as my positive control./v1/samples/clipsis the real case, and it is worse than described: absent from all three, including the gateway's own index.Why the capability index is not sufficient either
The gateway publishes a capability index, and it would be tempting to treat it as the live route table. It is not: it is derived from the route-to-scope map, so a route dispatched pre-auth never consults a scope and therefore cannot appear in a scope-derived index. That is a class, not an oversight.
/v1/samples/clips— a deliberate, free, unauthenticated developer sample route — answers 200 and appears in none of the three artifacts.So the index is an advisory enumerator; the probe is the authority. Same discipline the fleet has paid for twice elsewhere: a Worker's runtime environment is not its committed
wrangler.toml, so repo-only verification of anything env-keyed is unsound. If we claim something about production, we probe it.The probe semantics are the load-bearing part
An unmapped path answers 403 with
error.code: ROUTE_NOT_MAPPED. Anything else — including 402 — means the route exists.A 402 is not an absence. It is the strongest evidence of presence available: mapped and priced. Reading a paywall as "route not found" would blind this gate to exactly the routes that charge customers money, inverting its purpose. A test asserts this by name so nobody can quiet a noisy run that way.
A bare 403 is also presence — an authorization failure proves there was something there to be unauthorized for. Only the explicit code counts as absence. A 5xx or timeout is INDETERMINATE, never absent, so an origin having a bad minute cannot silently clear a real finding.
Cost: nothing. Every probe is an unauthenticated GET at concurrency 4. No credential is sent, so no tenant, meter or balance is touched, and the 402 is returned before any work — the challenge is the response. No paid calls, no POSTs, no load testing.
Two false positives I removed by narrowing the claim, not the gate
An earlier draft reported 21 findings. Two classes were my own gate overreaching, and I fixed them by refusing to assert more than the evidence supports:
ROUTE_NOT_MAPPEDto a GET while its POST is perfectly live. Those are now INDETERMINATE and surfaced — unknown is not a pass, and it is not a finding either. Closing that gap properly means probing the declared method, which for a POST is a write this gate will not do./robots.txt,/healthand similar are outside the spec's ownservers[0]base. Scoped out by that base, so the entire/v1surface stays in scope; a control test proves an undeclared/v1route is still caught. This is a scope rule, not a suppression.Tests
20 new tests, fully offline, injected
fetch— no network on the PR path. Full.github/scriptssuite: 59/59.Built so they cannot pass vacuously: the previously-invisible condition fails; positive controls prove the gate discriminates rather than blanket-failing; the 402 semantics are pinned by name.
Mutation proof: reading 402 as an absence fails 2 tests. Removing the
live-undeclareddirection — reducing this back to a two-artifact comparison — fails 6, including one that asserts explicitly that the two-artifact comparison finds nothing on the input the live probe catches.The scheduled job will be RED
It exits 2 today, on real findings. That is the correct outcome and I have not softened anything to avoid it. Each finding clears by documenting the operation, withdrawing the route, or adding an allowlist entry with a real justification — the allowlist ships empty on purpose. The specific routes are in the run artifact, which is deliberately not committed: it enumerates the live route surface and this repository is public.
