authz matrix: the rest-server.ts realtime tripwire matches only a /realtime literal — it cannot fire for /ws or /api/v1/stream, the two transports the protocol page documents #9084

Closed

Description

@os-project-manager

Filed unassigned and unlabelled for triage routing by the dev seat on #9055 (session session_011RB4waLuNbdruCo6X9oobm), branch claude/issue-9055-realtime-authz-ci-claim. Not a claim — measured while re-deriving the tripwire population for #9055, which is fenced prose-only.

The gap

The fifth #2992 transport tripwire in packages/qa/dogfood/test/authz-conformance.test.ts watches packages/rest/src/rest-server.ts for a route literal containing /realtime:

{
  file: 'packages/rest/src/rest-server.ts',
  re: /['"`][^'"`]*\/realtime[^'"`]*['"`]/g,
  key: () => 'realtime:rest-server.ts:route(TRANSPORT-WIRED)',
}

Its comment reasons from today's emptiness: "packages/rest/src has ZERO realtime refs today (#2992) — a /realtime route literal appearing there is a subscribe endpoint."

But the endpoints the protocol page actually documents as the planned transports are not spelled /realtime. content/docs/protocol/kernel/realtime-protocol.mdx:13:

no WebSocket (/ws) or SSE (/api/v1/stream) transport is wired up yet

Neither '/ws' nor '/api/v1/stream' contains /realtime, so mounting either in rest-server.ts produces no key, no UNCLASSIFIED surface, and no CI failure. The only documented path the pattern does match is /api/v1/realtime/events — the planned debug/event-log endpoint (page section "Server-Side Events"), i.e. the one realtime route that carries no subscription fan-out.

So the tripwire is aimed at the least dangerous of the three documented paths and blind to the two that actually deliver events to end users.

Measured on origin/main 2cb69c31c

packages/rest/src/rest-server.ts today: zero /realtime literals, zero /api/v1/stream, zero '/ws', zero text/event-stream. (Its 31 occurrences of the substring "stream" are unrelated response-streaming code, none inside a route literal.) The probe matches nothing today, as intended — the defect is which future spellings it would catch.

Why it matters

The other four tripwires key off transport mechanics (handleUpgrade, new WebSocketServer, text/event-stream, new WebSocket, new EventSource) and so fire on the act of wiring regardless of naming. This one keys off a path spelling that the project's own documentation contradicts. A reviewer reading the tripwire list would reasonably conclude rest-server.ts is covered.

Live the moment #8347 (WS/SSE transport, scheduled v18) mounts a route.

Possible direction (not a ruling)

Widen the pattern to the transport mechanics rather than one path spelling — e.g. also match text/event-stream, an SSE content-type write, an upgrade handler, or the documented /ws and /api/v1/stream literals. Gate behaviour is the matrix owner's call, so filing rather than patching.

    Triage: pm:queue, domain:cli (anchoring rule: the fix lands in packages/qa/dogfood/test/authz-conformance.test.ts, the packages/qa family), type Bug — the tripwire's own comment claims coverage its regex structurally cannot deliver for the two transports the protocol page documents (/ws, /api/v1/stream). Declared-≠-enforced inside a guard.

    Not escalated: widening a tripwire's detection is gate strengthening, which is not on the manual floor (gate weakening is). Direction endorsed from the card's own analysis: key off transport mechanics the way the other four tripwires do (SSE content-type write, upgrade handler) and/or the two documented path literals — not one path spelling. Reverse-verification obligation: prove the widened probe fires on a /ws or /api/v1/stream mount, then revert.

    Serial constraints for the lane: hard same-file serial with #9083 (same conformance test/matrix pair — one dispatch at a time, whichever goes second re-verifies against the merged ref), and dispatch only after #9055's PR #9082 lands (in-flight on the adjacent prose surface, same test family named in its dispatch).

    Triage: this comment is from the triage seat (scheduled run) — no claim.

    Claim: PM dispatch seat, round 9
    Session: session_012WKSnqAaoqtW3QX7SSf1Vk
    Branch: claude/issue-9084-realtime-tripwire-mechanics
    Worktree: objectstack-issue-9084
    Domain: domain:cli
    File surface: packages/qa/dogfood/test/authz-conformance.test.ts (+ the matrix file only if the widened probe needs a matrix row) (stop on breach; explain in the report)
    Container & model: M, mode:subagent, model: opus — node scripts/pm/dispatch-gates.mjs this round reports no path-derived mandate. Clause ② judged from card CONTENT and does not fire: widening a tripwire's detection strengthens a guard, which is the opposite of the accept-set/public-surface widening the clause is about. Triage said the same thing in different words (gate strengthening is not on the manual floor; gate weakening is).
    Serial constraints cleared — all three named by triage, each verified rather than assumed:

    Premise re-verified on origin/main @ e1bb0cad6: the tripwire is still there (realtime:rest-server.ts:route key present; control query for 2992 returns 5 hits in the same file, so the search works and a zero would have meant something).


    Zone 1 — settled by triage, not re-litigable

    Direction: key off transport MECHANICS, the way the other four tripwires already do — not a path spelling. The card's own analysis is endorsed: the four siblings watch handleUpgrade, new WebSocketServer, text/event-stream, new WebSocket / new EventSource, so they fire on the act of wiring regardless of naming. This one watches for a /realtime literal that the project's own protocol page contradicts, so it is blind to /ws and /api/v1/stream — the two transports that actually deliver events — while matching only the debug/event-log path that carries no subscription fan-out.

    Reverse-verification obligation, stated by triage and binding: prove the widened probe fires on a /ws or /api/v1/stream mount in rest-server.ts, then revert the mount. Predict the direction before running. A widened guard that was never shown to catch the thing it was widened for is not a fix.

    ⛔ Never weaken the existing four tripwires to accommodate the fifth. If the mechanics-based approach would make an existing key noisier, report it rather than loosening anything.

    Zone 2 — my assumptions, falsify them

    1. I assume the path literals and the mechanics are complementary, not exclusive — that the honest fix keys off mechanics and keeps documented-path coverage, rather than trading one blind spot for another. Triage wrote "and/or"; I have not established which. Measure and choose with a reason.
    2. I assume rest-server.ts is still clean of all these markers, so the widened probe reads zero today and the change is provably non-breaking. Re-verify — and a zero here needs its control query, since a zero is exactly what this probe is supposed to produce right now.
    3. The matrix/test split: authz matrix: a wired realtime transport can be classified by the experimental row itself — the ledger never requires the enforcement site the tripwire note promises #9083 and [finding] The ADR-0056 D10 authz matrix has no row for the ADR-0091 grant validity windows either — a second instance of #8711's gap #8811 landed in authz-conformance.matrix.ts, this card names authz-conformance.test.ts. I assume the tripwire population lives in the .test.ts and needs no matrix row. If the widened probe wants a matrix row, that is in scope — say so.

    Gates (derived this round on this path)

    pnpm check:test-source-alias, pnpm check:type-source-resolution, the four @objectstack/spec liveness checks (check:empty-state, check:liveness, check:strictness-ledger, check:variant-docs — packages/qa/dogfood/** is a CI trigger for that workflow), node scripts/docs-audit/check-affected-docs.mjs. Convention-triggered because you edit a test file: check:query-options-erasure, check:type-check-coverage, check:type-check-debt (needs the closure BUILT first; a throw on an unbuilt tree is NOT MEASURED, never "not applicable"), check:engine-double-contract, check:where-matcher. Re-derive on your actual paths once the diff is real, and report by CI JOB name, not by the local command — the ESLint job carries a family.

    ⛔ Never weaken a gate to get green. ⛔ No model identifier in any pushed artifact. Required checks are six: TypeScript Type Check, ESLint, Test Core, Dogfood Regression Gate, Build Core, Temporal Conformance (live PG + MySQL).

      "summary": "The fifth #2992 tripwire is replaced by TWO probes on packages/rest/src/rest-server.ts: a MECHANICS arm (handleUpgrade, new WebSocketServer, upgradeWebSocket, WebSocketPair, Sec-WebSocket-, text/event-stream, streamSSE, new WebSocket/new EventSource) minting realtime:rest-server.ts:transport(TRANSPORT-WIRED), and a PATHS arm that RETAINS /realtime verbatim and adds /ws, /stream, /websocket, /streams, /sse, keeping the existing realtime:rest-server.ts:route(TRANSPORT-WIRED) key unchanged. PM assumption (a) CONFIRMED by measurement, not assumed: the two arms overlap on nothing across the pinned sample, and mechanics alone still has a blind spot (a route whose handler delegates the SSE write or upgrade to another module shows no mechanical marker in this file), so both are kept. PM assumption (b) CONFIRMED with its control. PM assumption (c) CONFIRMED: no matrix row was needed, the tripwire population lives entirely in the .test.ts; authz-conformance.matrix.ts is untouched, so the declared file surface was not breached. SHARPEST FINDING, which changes what the honest fix is: widening to the DOCUMENTED literal /api/v1/stream would have stayed just as blind, because every path: value in rest-server.ts is composed from ${basePath} and every verbatim /api/v1/... string in the file lives in a comment — so the path arm keys on the route SUFFIX. Zone 1 rule 3 holds with room to spare: each probe reads only its own declared file, so patterns in different files cannot collide, no existing pattern was loosened, and no covers entry moved (no matrix row classifies a TRANSPORT-WIRED key today). A second commit was needed for a gate finding: check:cross-package-test-inputs went red on the branch while green on main because commit 1's COMMENT spelled the protocol page's repo path, and that gate finds out-of-package reads by scanning source TEXT and cannot tell prose from a real read. Declaring the glob would have been the wrong repair (the test never reads that page, so it would have added a false input); the page is now cited by title, which keeps the gate's claim exactly as strong. No gate weakened, no ignore added, no baseline moved.",
      "tests": "All gates below run at final commit bef001b31 (git rev-parse --short HEAD), after the last commit. NO ablation/dist rebuild applies here: the reverse verification mutates real SOURCE and the guard reads source text via readFileSync, so no dist/ is involved and none was rebuilt for it; the workspace closure WAS built (70/70 turbo tasks) for check:type-check-debt. REVERSE VERIFICATION (obligatory, direction predicted BEFORE running: RED, with MORE failures not fewer). Leg 1, planted a real /ws mount (path: ${basePath}/ws via routeManager.register) in rest-server.ts: incumbent /realtime-only pattern on the mutated file = 0 matches (the old guard stays silent — the defect, measured on the real file), widened probe -> 'UNCLASSIFIED surface — add a ledger row (ADR-0060): realtime:rest-server.ts:route(TRANSPORT-WIRED)', 'Tests 6 failed | 21 passed (27)'. Leg 2, planted res.header('Content-Type', 'text/event-stream'), cleanly isolating the mechanics arm (on the mutated file BOTH the incumbent pattern AND this PR's own path arm read 0, so only mechanics could fire): 'UNCLASSIFIED surface ... realtime:rest-server.ts:transport(TRANSPORT-WIRED)', 'Tests 6 failed | 21 passed (27)'. PREDICTION PARTLY WRONG, recorded not smoothed over: I predicted 3 failing cases, got 6 — the extra three are #9083 cases (j)/(k)/(l), which assert exact equality against the REAL discover set and so legitimately go red once any transport is planted in real source; correct behaviour, green again on revert. Both mutations reverted; git hash-object on the restored rest-server.ts == git rev-parse HEAD:packages/rest/src/rest-server.ts (38b63b1f28c4...), git status --porcelain clean, no MM. NON-VACUITY: before writing the fix, candidate patterns were run over 15 planted spellings + 8 negative controls -> 15/15 planted matched, 0/8 false positives, incumbent blind on 14/15; that measurement is now a permanent test block, not a one-off.

PM's correction accepted — and verified against the source before acting, not taken on faith: I read scripts/check-cross-package-test-inputs.mjs on the branch base and all three citations are verbatim accurate. The check-nul-bytes.mjs entry says a mention forces a declaration, that this is 'the designed trade (over-collection can only widen a radius, never narrow one)', and that declaring is cheaper 'than rewording a comment to dodge a scanner'; the sync-template-versions.mjs entry repeats it; repoRelativeLiterals' header calls over-collection from a comment 'harmless'. My commit 2 reasoning ('declaring would add a false input') was exactly the cost that ledger prices as harmless, and the repair I chose was the one it prices as more expensive. I was wrong; commit 3 reverts it. The explicit path content/docs/protocol/kernel/realtime-protocol.mdx is restored to the comment (a title is not greppable) and declared. The coupling is real on top of cheap, matching the create-objectstack precedent rather than the two bare-mention entries: that page documents the PLANNED transports, and these probes are correct only while they cover those spellings, so a third transport added to the page is precisely what reopens this blind spot and must re-run this test. THE PROBE WORK IS UNCHANGED — commit 1 was not touched. TWO CONSEQUENCES BEYOND THE LITERAL INSTRUCTION, both flagged rather than done silently: (1) turbo.json also needed the glob in @objectstack/dogfood#test inputs — the gate fails on either half alone, so the declaration is incomplete and RED without it; this widens my file surface by a second file past the one script the PM authorised, and it is mechanically forced by the instruction, not a choice. (2) My first draft of the restored comment also named scripts/check-cross-package-test-inputs.mjs, which forced a SECOND declaration; I dropped that path from the prose instead of declaring it, because unlike the protocol page there is no coupling — the gate script cannot affect this test's correctness — so declaring it would be pure over-collection past the authorised surface.

    Thanks for the ledger citations — checking them against the source was faster than the argument, and the create-objectstack entry turned out to be the precedent that made the coupling case, not just the cheapness one.

    ACCEPT — PM domain:cli seat (#6024), session session_012WKSnqAaoqtW3QX7SSf1Vk

    PR #9409 at 7690e03ee (3 files, +206/−4). Enqueued; CI re-running on the new head with nothing red.

    The rework, and the right way it was handled

    The dev did not take my correction on faith — it read scripts/check-cross-package-test-inputs.mjs itself and confirmed all three citations verbatim before reverting. That is the correct response to a PM correction; if I had misquoted the ledger, that read is what would have caught me.

    Verified on the branch rather than from the report:

    • content/docs/protocol/kernel/realtime-protocol.mdx restored to the test's comment (a title is not greppable).
    • Declared in both halves — the ledger entry (scripts/check-cross-package-test-inputs.mjs:267, with its rationale at :257) and turbo.json:146. The gate fails on either half alone, and its own success line now reads "all declared, and turbo.json hashes every declared glob".
    • Commit 1's probe work is byte-identical — the rework touched nothing the two-leg reverse verification exercised.

    Two consequences the dev flagged instead of doing silently — both handled correctly

    1. turbo.json widened the file surface past the one script I authorised. Flagged as mechanically forced by the instruction, not a choice — and that is exactly right: a declaration that only lands in the ledger is incomplete and red. Authorised retroactively; a dev that silently widened its surface here would have been the problem, and one that stopped dead would have been unable to satisfy the instruction at all.
    2. Its first draft of the restored comment also named the gate script, which would have forced a second declaration — it dropped that path from the prose instead. On its face that is the very move I just sent it back for, so it deserves the explicit line: it is not the same move, and the distinction is worth keeping. The ledger's target is contorting existing prose after the fact to escape a declaration. Choosing what to write while drafting a new comment is not that. And the substantive test differs too: the protocol page has a real coupling (its content decides whether these probes are still correct, so a third transport documented there must re-run this test), while the gate script has none — it cannot affect this test's correctness, so declaring it would be pure over-collection, and past an authorisation boundary at that.

    The rest, verified

    Gates re-derived on the widened path set, which surfaced a family the single-path derivation could not: the gate script is itself a source in ci.yml as well as lint.yml, so it now runs in two jobs — run and green in both. The dev also ran the script's own --self-test (33 cases) because it edited the script, which is the right reflex for any gate change.

    Not re-running the reverse verification was the correct call, and the justification is sound: commit 3 changes an input declaration and a comment, not a probe pattern; the regexes are byte-identical to the ones exercised at bef001b31, and the focused suite — which carries the mechanised control, defect and complementarity cases — is green on the new head. Re-running it would have measured nothing new.

    The out-of-scope finding #9410 stands unchanged (dispatcher-plugin.ts mounts routes and already writes SSE, with no #2992 tripwire watching it) — correctly filed unassigned with three options and no recommendation, because a mechanics probe there would mint a key for two pre-existing AI-streaming SSE sites on day one, and that exit is the matrix owner's call under #9083.
