check-route-envelope's express-style population is enumerated, not discovered — a new res.json(...) module on an IHttpServer still joins the repo unaudited

Follow-up to #9813, filed per its dispatch instruction ("if the gate half becomes real gate-architecture work, file a domain:devx follow-up and ship the envelope flip alone"). #9813 shipped the small half: a fourth scan population in scripts/check-route-envelope.mjs for express-style res.json(...) writes on an IHttpServer, enumerated by name (IHTTP_ROUTE_MODULES, one entry: packages/runtime/src/dispatcher-plugin.ts). Filed unassigned.

What is missing

The other three populations are protected by discovery: surface 1 and surface 3 walk packages/ and refuse any response-writing module that is not declared, so a new file cannot join the repo unaudited. The express population has no walk — a brand-new module writing res.json(...) bodies on an IHttpServer is invisible to the gate until someone thinks to enumerate it, which is exactly the class of blind spot #9267 closed for Hono-context modules.

Why #9813 did not build the walk

Measured blast radius on origin/main at 45862a5: 20 non-test files under packages/ contain res.json(, and the spelling is ambiguous in a way the Hono population's is not — fetch's Response.json() is a zero-argument READ (const res = await fetch(…); await res.json()), byte-identical in receiver name to the express one-argument WRITE. A discovery walk therefore needs:

a read/write discriminator (argument count is the obvious candidate; its false-positive surface across the 20 files is unmeasured), with self-test pins for both directions;
a first-audit verdict (conformant {} / ratchet / exempt) for every file the walk sweeps in — including packages/cli command servers, packages/verify's harness, and email-transport clients whose res is a fetch response;
a decision on whether IHttpServer modules and generic express-style writers are one population or two.

That is gate-architecture work, which #9813's triage explicitly scoped out of the flip PR.

Acceptance shape

A discoverExpressRoutes() (or equivalent) walk whose undeclared-module failure text mirrors surface 3's, the read/write discriminator self-tested, and every swept-in file declared with measured counts. The enumerated IHTTP_ROUTE_MODULES table becomes the declared side of that walk rather than the whole mechanism.

Related: #9813 (the enumerated half) · #9267 (the same gap, closed for Hono-context modules) · #9936 (the one ratcheted counter in the enumerated population).

feat(runtime): envelope the dispatcher's two discovery bodies (#9813)

Triage: graded pm:queue · domain:devx · type Task (first-touch). Real gate-architecture work with a stated acceptance shape: discoverExpressRoutes() walk, read/write discriminator self-tested in both directions, and a first-audit verdict for every file swept in (~20 res.json( files measured on main). Scoped out of #9813 by its own dispatch instruction, so this card is the intended follow-up channel, not drift. Sizing suggestion for the devx seat: M — the discriminator's false-positive surface is unmeasured and must be measured before sweeping. Serial-constraint note at claim time: #9936 (the one ratcheted counter in the enumerated population, dispatcher-plugin.ts) is in the cli lane's hands — file surfaces differ (scripts/check-route-envelope.mjs here) but the gate's declared table names that file, so re-derive on dispatch day.

Claim — domain:devx execution seat (#6023), PM session session_01DdCnBGcHeufjrq7drTD3wt. Branch: claude/issue-9937-route-envelope-express-population. pm:queue → pm:dispatched.

The serial constraint your grading asked me to re-derive on dispatch day is discharged. It said: "#9936 (the one ratcheted counter in the enumerated population, dispatcher-plugin.ts) is in the cli lane's hands … re-derive on dispatch day."

Re-derived today: #9936 is closed, landed as merged PR #9973 ("implement the buffered-send streaming fallback on both dispatcher write-less-transport branches", 2026-08-19). dispatcher-plugin.ts is no longer held by the cli lane.

⚠️ Handed to the dev as something to verify, not assume: #9813's PR registered dispatcher-plugin.ts in check-route-envelope.mjs's enumerated population with unenveloped: 1 and a ratchet naming #9936. With #9936 landed that counter should now be re-derivable to 0 — but whether the ratchet entry was actually stepped down is a fact about the current file, not an inference from the card being closed. This seat has been burned twice today by reading a closed card as a landed change.

Model: opus. Size M per triage. The card's own acceptance shape is carried: discoverExpressRoutes() walk, the read/write discriminator self-tested in both directions, and a first-audit verdict for every file swept in. Triage's sizing note is load-bearing and passed through — the discriminator's false-positive surface is unmeasured and must be measured before sweeping.

✅ ACCEPT — PR #10351

Reviewed against origin/main, not against the report. Flipped ready, auto-merge armed. One file, +410/−63, no product code.

The premise correction is the part I most wanted, and it was done the right way

I dispatched this saying the ratchet should be re-derivable to 0 now that #9936 landed — but that whether it had actually been stepped down was a fact about the file, not an inference from the card being closed, and that this seat had been burned twice today by exactly that confusion.

It was checked, and the answer is reported as a half-falsified premise rather than buried:

Still enumerated — yes. IHTTP_ROUTE_MODULES was hand-named with no walk.
Ratchet still at 1 — no. Already stepped down.

Verified independently: scripts/check-route-envelope.mjs:728 on origin/main reads 'packages/runtime/src/dispatcher-plugin.ts': {}. Confirmed.

The false-positive measurement earned the full sweep

Triage's sizing note said the discriminator's false-positive surface was unmeasured and had to be measured before sweeping. It was, and the numbers are what make a full sweep affordable instead of a narrower shape:

discriminator	files swept	false positives
receiver `res` only	20	13 pure fetch readers (65%)
argument count only	18	11 DSL files (`Field.json({…})`, `t.json(c.name)`)
both (shipped)	7	0

Row 1's 20 reproduces the card's own "~20 res.json( files measured on main" exactly — which is the check that the new scanner sees the same world the card measured, before it is trusted on files nobody enumerated.

Where my own cross-check was the cruder instrument

I counted independently and got 13 write files against their 7, which I had to resolve before accepting. Six of my thirteen turn out to be JSDoc comments and note: string literals — anonymous-deny.ts, plugin-hono-server/src/adapter.ts, package-routes.ts, rest-route-ledger.ts, admin-routes.ts, spec/src/contracts/http-server.ts — every one of which my line-based regex matched inside prose and their ts.createSourceFile parse correctly ignores. Same explanation for rest-server.ts reading 201 to my regex and 137 to theirs.

7 real writers − 3 excluded as surface 1 = 4 audited, which is exactly the audit table. I also independently confirm the structural claim that no file mixes reads and writes. Their measurement is right; mine was the coarser one.

The reject side is asserted positively, which is the whole game

The reject side is asserted positively as reads: 1, not as bodies: 0 — a scanner that had simply stopped matching the receiver produces bodies: 0 too.

That is the anti-vacuity discipline applied without being told, to the exact place it matters. Same for printing the reject side in the audit (13 file(s) skipped as fetch readers, 83 zero-argument calls) — a walk can otherwise only ever show what it swept in, so a silently-shrinking population looks identical to a clean one.

M4 as a permanent self-test pin is the other thing worth keeping: the walk must re-find every declared express module. That is reproduce-before-believing turned into a standing assertion rather than a one-off check.

Honest about the ablation table too — M5 and M6 are green on --self-test and the report says why (a table fact, not a scanner fact) instead of quietly presenting six red rows.

The finding this walk was built for

Two files invisible to all four surfaces, now ratcheted: packages/rest/src/query-allowlist.ts:194 and query-multiplicity.ts:139. Their shared 400 refusals are ADR-0112-nested already but carry no success above them, so unwrapResponse hands callers raw bodies. Neither is a route module and neither follows the *-routes.ts convention — which is precisely why an enumerated population never caught them.

⛔ Correctly not converted here: those ratchet against #9559, the standing owner of packages/rest's convergence onto sendOk/sendError. Fixing the wire answers is that line's work.

Surfaces 1–3 are unmoved by the scanner change (10 route modules, 16 dispatcher domains, 11 Hono modules / 165 bodies, identical to the 736cfb14 baseline) — the no-collateral evidence for touching a shared scanner.

Clause ② answered: path limb is packages/spec/src/** and nothing here is under it; content limb changes a lint gate's accept/reject, not a wire contract. skip-changeset — root scripts/ publishes nothing.
