From 7bc63c99bfb5f2be1cf18defcd81c915cf9f5f6a Mon Sep 17 00:00:00 2001 From: Vikrant Puppala Date: Sat, 30 May 2026 11:58:48 +0000 Subject: [PATCH] follow-up: review-squad LOW/MED follow-ups (5 items) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Stacked on top of PR #390 (security-bump-runtime-and-dev). Addresses the LOW/MED findings from the self-review pass that were intentionally deferred from the main PR to keep its scope tight. - F4: Add SECURITY-OVERRIDES.md — document each of the 18 entries in package.json's overrides with provenance (CVE id, dependent chain, exit condition). Reference it from CONTRIBUTING.md. Pure docs. - F2: lz4 test ESM-safe — refactor lib/utils/lz4.ts to expose setLz4LoaderForTest()/resetLz4CacheForTest() seams so the suite can inject stubs without patching Module._load. Drops the Node-22+ conditional skip; suite now runs on every Node version (16/18/20/22/24). 904 → 904 passing on Node 16/18/20 (unchanged), 898→904 on Node 22/24 (lz4 suite re-enabled). - F8: FederationProvider HTTP exchange tests — refactor to expose a setFederationFetchForTest() seam, then add 3 unit tests that exercise the exchange branch where the AbortController + node-fetch shim typing fix lives. Verifies (a) signal reaches fetch as an AbortSignal, (b) signal implements the standard contract, (c) failed exchanges fall back to original token. 904 → 907 passing. - F11: e2e parallel-safety audit — verified all DDL in tests/e2e/ is templated against E2E_TABLE_SUFFIX and staging files use uuid.v4(). Added tests/e2e/README.md documenting the parallelism contract and warehouse capacity considerations. - F14: OAuthCallbackServerStub interface-drift refactor — dropped the pile of no-op shim methods (setTimeout, closeAllConnections, address, ref, unref, Symbol.asyncDispose, etc.) that existed only to satisfy http.Server's structural type. Production code calls only listen() and close() on the stub, which it does implement. The test-site cast in AuthorizationCode.test.ts already carries the "trust me, this is Server-shaped" assertion via `as unknown as ...`. Drive-by lint-script fix: switched the lint script's glob from `tests/e2e/**` (which expanded to .md files and made eslint complain) to `tests/e2e/**/*.{js,ts}`. Same scope, no false positives. Verified locally: prettier, lint, tsc --noEmit, and npm test (907 passing) all clean on Node 16/18/20/22. OSV-Scanner still reports zero findings on the lockfile.
