From 93322a6412ad6b0e1c16286a7a15ac53806bc68e Mon Sep 17 00:00:00 2001 From: Rishi Tank Date: Thu, 8 Oct 2026 14:23:55 +0100 Subject: [PATCH 01/19] feat(runtime-gate): add the runtime-gate toolkit Composite action with a deterministic browser crawler that fails on runtime errors, an advisory Gemini explorer, a static file server, and self-tests against healthy and broken fixture sites.

never re-post forms via history - Sign in first: the signed-out crawl fills open sign-up forms with ci@example.com and could claim the test account's address before the gate registers it (seen on quarterdeck). - login-check: only a form with a single password field counts as "still on the sign-in page", so a signed-in settings page with a change-password form no longer reads as a failed sign-in (seen on quarterdeck). - After submitting a form, always reload the page, and the client-side navigation pass returns to / with goto instead of goBack: going back to a form result re-posts the form, which produced false 4xx findings. - Regression tests for all three.

(Completes 858b3d0, whose message described these two files.) - Self-tests start every server on port 0 and read the port it prints, and fail fast if a server exits before listening, instead of polling fixed ports that another process could hold. - The ignore-list test now asserts the crawl ran (exit 1, the page that logs the ignored message was visited) and that other errors still block. - New: a form's own POST answering 404 is a warning while an unrelated GET 404 in the same window still blocks (fixtures/broken/signin.html); a rejected sign-in that leaves a password + security-code form on the sign-in page is a blocking login-failed (fixtures/app-server /login-code). Both fail against the previous code.

pin third-party actions; docs - runtime-gate.yml: the runtime job (which runs the app's install, build, migrate and start) drops pull-requests: write and keeps contents/actions read. The sticky comment moves to a separate `comment` job that needs runtime, downloads only the runtime-gate report artifact, reads it as text, and is the only job holding pull-requests: write. - Every third-party action in runtime-gate.yml, runtime-gate-flows.yml and runtime-gate-selftest.yml is pinned to its full commit SHA with the tag as a trailing comment (same versions as before), so Renovate's digest pinning keeps them current. - runtime-gate-selftest.yml: say why `node-version: current` (account policy, and what action.yml installs) and why callers still grant pull-requests: write (a caller must grant what a called job declares). - upgrades.test.mjs: servers on free ports; a regression test for the two-password sign-in form. - docs/runtime-gate.md: form 4xx scoping, the comment job and the grant it needs, the sign-in check, the Gemini data-use terms with the source link, grammar.
