Conversation
The post-deploy verify step treated an unresolved host as a pass: when resolve-deploy-host.mjs returned nothing, the step printed a ::notice and exited 0 regardless of environment. That already let a real production deploy through with zero verification (wave-email-edge run 33994760933) because resolve-deploy-host.mjs did not recognize the wrangler.toml shape and silently produced no host. Production always has a routable host once it is live, so "no route" after a production deploy means the resolver or the toml regressed, not a legitimate skip. Add a hard ::error + exit 1 for TARGET_ENV == production, inside the existing zero-host branch, before the notice/exit-0 fallback that the other environment keeps. Ports the fix merged in wave-av/wave-spoke-template#77 and exemplified in wave-av/wave-seo#71. Tracked in wave-av/wave-foundation#1453.

…-deploy-host The prior commit (this PR) fixed the fail-open two-state bug by hard-failing production whenever resolve-deploy-host.mjs printed nothing, but that conflated two different absences: a route declared but unparseable (a real regression, must fail) with no route declared at all (a legitimate skip, e.g. this repo's canary, which deliberately sets routes = [] per the ROUTE ISOLATION incident 2026-07-12). A whole-file declared-anywhere scan would misfire here specifically: production's top-level routes key would make canary's deploys look declared-but-unresolved and fail closed on every canary dispatch, which is exactly the over-collapse gitar-bot flagged on wave-vision-ingest#15. resolve-deploy-host.mjs now emits a four-state exit code (0=resolved, 1=declared-but-unresolved, 2=nothing declared, 3=resolver crashed), with the declared check scoped PER ENV exactly like the existing host resolution walk (top-level-before-first-table for production, the env.<name> section for anything else) so canary's own routes = [] reads as nothing declared for canary, not production's route seen from canary's perspective. deploy.yml's post-deploy verify step now branches on the resolver's real exit code (captured via set +e / dollar-question instead of || true, which discarded it) instead of on env name or string emptiness. Measured for this repo: TARGET_ENV=production resolves to rt.wave.online (exit 0); TARGET_ENV=canary resolves to exit 2 (no route declared for canary, by design, not a failure). Ports wave-av/wave-spoke-template's corrected four-state contract. Tracked in wave-av/wave-foundation#1453.

@gitar-bot — engaging your review on the first commit rather than dismissing it. Your approval ("Adds production-only hard-fail to post-deploy verification when the host resolver returns empty... No issues found") was correct in scope for the diff you reviewed. The shape itself, though, was insufficient — the same two-state pattern (hard-fail on ANY empty resolver output for production) is what your own team's review caught elsewhere in this fleet on wave-av/wave-vision-ingest#15: it conflates "a route is declared but the resolver failed to parse it" (a real regression, must fail) with "no route is declared at all for this env" (a legitimate skip). This repo makes that distinction concrete: canary deploys via [env.canary], which deliberately sets routes = [] (incident 2026-07-12, ROUTE ISOLATION comment in wrangler.toml). A whole-file "is anything declared" scan would have read production's top-level route as "declared" while resolving canary, turning canary's deliberate empty route into a false "declared but unresolved" — a hard failure on every canary dispatch. Measured directly: node scripts/ci/resolve-deploy-host.mjs canary now correctly returns exit 2 (nothing declared for canary, not a failure), and production returns exit 0 with host rt.wave.online. This PR now carries a second commit porting the corrected four-state contract (0=resolved, 1=declared-but-unresolved-for-THIS-env, 2=nothing-declared-for-THIS-env, 3=resolver-crashed), with the declared-check scoped per env specifically to avoid the canary false-fail above.

…n resolve-deploy-host
coderabbitai review on this PR flagged two real gaps in the just-added
four-state discriminator:
1. resolveProductionHost() required routes = [ ... ] and pattern = "..."
on the SAME line, but hasDeclaredRoute() counted a multiline top-level
routes array (routes = [ on its own line, the pattern on the next) as
declared regardless. A cosmetic reformat of a genuinely valid
production route (no change in what is actually configured) would
therefore resolve to null while still counting as declared, producing
a false exit 1 (fail closed) on a config that was never broken.
resolveProductionHost() now scans for pattern = "..." on ANY top-level
line before the first [table], matching the style
resolveNamedEnvHost() already uses for env sections.
2. hasDeclaredRoute()'s emptiness check compared the raw (unstripped)
right-hand side of a routes/route key against "[]"/"{}"/"" literally,
so a trailing comment (routes = [] # no custom route) survived into
the comparison and made a deliberately empty declaration register as
non-empty (declared). Added stripTrailingComment() (quote-aware, so a
"#" inside a pattern string is not treated as a comment) and apply it
before every route-key comparison.
Measured against this repo's actual wrangler.toml: unchanged (production
exit 0 / rt.wave.online, canary exit 2). Added fixtures for both gaps
plus the equivalent trailing-comment case on canary's own declaration.

…redRoute A sibling PR (wave-av/wave-realtime-edge#487) received a coderabbitai review flagging that hasDeclaredRoute()'s emptiness check compared the raw (unstripped) right-hand side of a routes/route key against "[]"/"{}"/"" literally, so a trailing comment (e.g. routes = [] # deliberately empty) survived into the comparison and made a deliberately empty declaration register as non-empty (declared). This repo's resolver was ported from the same lineage and carries the identical gap in its own hasDeclaredRoute(), even though this repo's actual wrangler.toml has no [env.*] sections today and so does not exercise it in practice. Added the same stripTrailingComment() helper (quote-aware, so a "#" inside a pattern string is not treated as a comment start) and apply it before every route-key line is classified, for both the top-level scan and the [env.<name>] section scan. resolveDeployHost()'s own top-level scan already tolerated a multiline routes array and a trailing comment on a resolved route (verified directly, not assumed) so no change was needed there — only the newly-added discriminator had the gap. Measured against this repo's actual wrangler.toml: unchanged (production exit 0 / bridge.wave.online, staging exit 2). Added fixtures for the trailing-comment-on-empty case (top-level and [env.production] scope) and confirmed multiline-array + trailing-comment-on-resolved-route were already handled correctly.
…claredRoute
isRouteKeyLine compared the routes/route key line against exactly three
sentinels ("", "[]", "{}") to decide whether a value was empty. A
multiline-reformatted empty array (routes = [\n]) puts only "[" on the
keys own line, so its rhs was the bare unbalanced string "[" -- a
fourth shape matching none of the three sentinels -- so the key was
misread as non-empty ("declared"), turning a legitimate exit-2 skip
into a false exit-1 fail-closed for both the top-level (production)
scan and the [env.<name>] section scan (canary).
Replace the three-sentinel check with isRouteValueEmpty(), which
tracks bracket depth across as many continuation lines as it takes to
close (comment-stripping each candidate line the same way the single-
line case already did), so it is correct regardless of how many lines
the empty array/table is split across -- not just one more literal
string. Ported from the same fix already landed in
wave-spoke-template#79.
Also adds the exit-3 (unexpected crash) test this four-state resolver
never had, spawning the script as a real subprocess. That test file is
TypeScript and imports node:fs/node:child_process/node:os/node:path
directly; this repos tsconfig.json scoped "types" to
@cloudflare/workers-types only (Workers-runtime types, no Node
ambient types), so add @types/node as a devDependency and to the
types array specifically to typecheck this new Node-side test code
without touching how src/ is checked.

What this fixes
The
post-deploy verify — proven live, not merely deployedstep in.github/workflows/deploy.ymlresolves the deploy host vianode scripts/ci/resolve-deploy-host.mjs "$TARGET_ENV". Before this PR'sfirst commit, when that resolution came back empty, the step printed a
::noticeand exited0— regardless of which environment was beingdeployed. That was fail-open: the step measured the absence of an
answer and rendered it as a pass, instead of distinguishing "this
environment intentionally has no route" from "production just lost its
verification."
This already happened for real, on a sibling worker. On the
wave-email-edgedeploy run 33994760933,resolve-deploy-host.mjsdidnot recognize the
wrangler.tomlshape it was given, produced no host fora live production deploy, and the post-deploy verify step quietly
exited 0. The worker happened to be live and correct that time, but the
gate proved nothing — it was luck, not verification.
Why this PR now carries a SECOND commit — the first fix was itself wrong
This PR's first commit fixed the fail-open bug by hard-failing production
whenever the resolver printed nothing. That was a two-state shape
(resolved / not-resolved), and it over-collapsed: it treated "a route is
declared but the resolver failed to parse it" (a real regression) the same
as "no route is declared for this env at all" (a legitimate, deliberate
skip). That over-collapse broke deliberately-routeless repos elsewhere in
the fleet before a review bot (gitar-bot, on
wave-av/wave-vision-ingest#15) caught it. This PR was deliberately heldback from merge specifically so it could land the corrected shape instead.
This repo has its own sharp edge that makes the distinction concrete:
canarydeploys via[env.canary], which deliberately setsroutes = [](incident 2026-07-12 — an inherited top-level route once leta canary steal the production custom domain;
wrangler.toml's own ROUTEISOLATION comment documents this). A naive "is a route declared ANYWHERE in
the file" scan would read production's top-level
routeskey as"declared" while resolving
canary, turning canary's deliberate emptyroute into a false "declared but unresolved" — a hard failure on every
single canary dispatch. That is exactly the class of over-collapse this PR
corrects.
The corrected fix: a four-state exit contract
scripts/ci/resolve-deploy-host.mjsnow emits one of four exit codes:The new
hasDeclaredRoute(tomlSrc, envName)is scoped per env, exactlymirroring this repo's existing host-resolution split: the top-level scope
(before the first
[table]) forproduction, or the[env.<name>]section for anything else — so canary's own
routes = []reads as"nothing declared for canary," never "production's route, seen from
canary's perspective."
.github/workflows/deploy.yml's post-deploy verifystep now captures the resolver's real exit code
(
set +e; HOST=$(...); RC=$?; set -e— replacing the old|| true, whichdiscarded the code entirely and is exactly what let the two-state bug
ship) and branches on it directly, independent of
TARGET_ENVstringcomparisons.

On the existing bot review
gitar-bot(and several other automated reviewers) approved this PR'sFIRST commit — the two-state shape — with "No issues found." That approval
was correct in scope (it reviewed the diff it was given) but the shape
itself was insufficient, per the
wave-vision-ingest#15catch referencedabove, which is why this second commit exists. Not dismissing that review
— flagging that the shape it approved has been superseded, and why, with a
concrete measured case (canary) showing what the old shape would have
broken.
