From 09d9b609de3bb510175ff49ab5fe588b218b78b6 Mon Sep 17 00:00:00 2001 From: secret-mars Date: Sun, 10 May 2026 22:57:11 +0000 Subject: [PATCH 1/3] fix(cache-invariants-test): match headers.set() Cache-Control form + add pattern coverage tests MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Address the gap @arc0btc flagged on #726 review: the regex set in `CACHE_CONTROL_PRIVATE_PATTERNS` didn't cover the common Next.js form `response.headers.set('Cache-Control', 'private, no-store')`. The first pattern requires a `['"\s:]+` separator between `Cache-Control` and `private`, which doesn't include `,`; the second pattern requires a `:` between key and value. The `.set()` form has a `,` argument separator, so it falls through both. When the first `auth-required-get` route lands, a contributor could correctly set the private cache header via `.set()` and Invariant 2 would still fail at test time — a confusing false negative. This commit: 1. Adds two regex patterns covering `headers.set('Cache-Control', 'private...')` (specific) and the generic `'Cache-Control', 'private...'` comma-separated form (catches `new Headers([['Cache-Control', 'private']])` arrays too). 2. Adds a `describe("hasCacheControlPrivate pattern coverage")` block with 7 positive + negative test cases pinning each form so a future regex tweak can't silently regress the coverage. 3. Adds a doc-comment over the pattern array enumerating which form each pattern handles, and a contributor note: "add a positive case before adding the pattern." Manually verified against all 7 cases via node REPL before commit (pattern 4 fires on the .set() form; pattern 1 still handles the comment/colon forms; negative cases stay negative). No runtime changes. Test-only.

Stale-marker check (Cairn blocker) The original posture-marker design protected against MISSING declarations on enumerated files but not against declarations becoming WRONG over time. A future PR that adds GET-side auth to `app/api/inbox/[address]/route.ts` while leaving `// CACHE_INVARIANTS:POSTURE=public-only-get` unchanged would have silently passed: extractPosture returns "public-only-get", marker test passes, auth-required Cache-Control check early-returns. The exact agent-news#802 scenario the test claims to defend against was not caught. New test: `if posture=public-only-get, GET handler must NOT contain auth tokens`. Scope-isolation is the load-bearing piece — the auth-import-detection pivot in #726 rejected file-scope auth scanning because POST/PATCH handlers legitimately import `verifyBitcoinSignature` for write-path sender auth, and the bug class (agent-news#802) only applies to GET-side cache HITs. So this new test extracts the GET handler's lexical scope (from `export async function GET(` to the next `export async function X(` or EOF) and scans ONLY that region. Additionally, string literals get stripped before scanning to avoid a false-positive that fires on the outbox 405 response body, which is a JSON-shaped docstring that mentions "BIP-322 signature" + "uses verifyBitcoinSignature" in error/help text. Verified against the real outbox/[address]/route.ts file before commit (the unfiltered scan flagged it incorrectly; the string-stripped scan returns clean). 7 new test cases under "extractGetHandlerScope + getHandlerHasAuthToken": - mixed-handler isolation (PATCH auth imports don't pollute GET scope) - stale-marker positive (auth-token in GET → caught) - no-GET-handler (write-only files → no check) - BIP_322 namespace use → caught - getServerSession call → caught - docstring-only mention (5xx body documenting POST) → NOT flagged (string-literal strip) - real auth + adjacent docs → caught (token outside string literal) ## 2. Glob auto-discovery — fail-closed on new routes (Cairn+Forge convergent) Original design: manual INBOX_ROUTE_FILES allowlist. Cairn+Forge convergent finding: a future `app/api/inbox/foo/route.ts` added without updating the allowlist silently does not get enforced. The fail-closed argument is independent of route count — even at 3 files today, the failure mode is real. New test: `INBOX_ROUTE_FILES allowlist must cover all discovered routes`. Uses Node's built-in `fs.readdirSync` (no new dep) to walk `app/api/inbox/**` and `app/api/outbox/**`, collects every `route.ts` / `route.tsx`, and asserts the allowlist is a superset. Discovery excludes underscore-prefixed directories (Next.js convention for `_internal/`, `_helpers/`, etc. that aren't part of the public surface) so private helper routes can be excluded deliberately. Dotfiles and `node_modules` also skipped for defense-in-depth. If a new route lands without being added to INBOX_ROUTE_FILES, this test fails with a message naming the file + how to add it to the allowlist OR how to exclude it via leading-underscore directory convention. ## 3. POSTURE_PATTERN block-comment support Original regex: `/\/\/\s*CACHE_INVARIANTS:POSTURE=([a-z-]+)/` matched only line-comment form. After prettier or eslint reflows that convert `// ...` into `/* ... */`, or in JSDoc-style headers where the marker would naturally be written as `* CACHE_INVARIANTS:POSTURE=...`, the marker would not match and the file would fail the "declare marker" check. New regex: `/(?:\/\/|\/\*\*?|\*)\s*CACHE_INVARIANTS:POSTURE=([a-z-]+)/` also matches `/* ... */`, `/** ... */`, and `* ... ` (JSDoc continuation). ## 4. Array-of-arrays Headers test case (arc nit) The doc-comment over CACHE_CONTROL_PRIVATE_PATTERNS already documented that `new Headers([['Cache-Control', 'private']])` is covered by pattern 4, but no test case locked it in. Per the discipline I documented ("add a positive case to the pattern coverage describe block BEFORE adding the pattern"), filled the gap. ## Verification Manually verified against the actual 3 route files via node REPL — all return clean (`✓ consistent`), no false positives. Verified the synthetic stale-marker scenario triggers as expected. Verified the discovery walk finds exactly the 3 existing route files (excludes `_internal/` etc.). Verified the docstring false-positive case is suppressed by string-literal stripping while real adjacent auth code still gets caught. No runtime changes. Test file only — moves from ~118 LOC to ~453 LOC, all additions in test/helper logic + 7 new describe blocks under `extractGetHandlerScope + getHandlerHasAuthToken`.

The strip was bypassed. CI failure on d457ecb: app/api/outbox/[address]/route.ts → flagged by /\bBIP[_-]?322\b/i because the GET handler's 405 NextResponse body documents the POST request shape via `signature: "string — BIP-137/BIP-322 signature (base64 or 130-char hex)"`. That string is doc/AX data, not auth code. @whoabuddy flagged this at https://github.com/aibtcdev/landing-page/pull/727#issuecomment-from-whoabuddy. This commit applies `stripStringLiterals(scope)` before the AUTH_TOKENS_IN_GET scan inside the structural enforcement test loop — which is the code path that actually runs against real route files. Updated assertion message to mention "after stripping string literals" so the failure mode is self-documenting. Verified locally against real outbox/route.ts: raw scope flags BIP-322 in the docstring at offset 1683 (".../signature: \"string — BIP-137/BIP-322 signature (base64 or 130-char hex)\"..."); scrubbed scope returns clean. Synthetic stale-marker scenario still fires correctly. Adjacent-real-auth-plus-docs scenario still fires correctly. Pure-docstring case no longer false-positives. Same v143/v158/v163-family "verify before publishing" lesson firing: I verified the helper works (`getHandlerHasAuthToken`) but didn't verify the structural enforcement test runs the same code path. The two code paths diverged; the helper test passed locally; the structural test failed in CI. Refactor opportunity: have the structural enforcement test go through the helper (single source of truth). Doing that here.
