Closes the CI-infra half of P0 #7's follow-up. PR #16 (squash commit
7e97254) added scoped permissions to both workflows but exposed that
Vercel Deployment Protection 401s anonymous GitHub-runner requests,
causing both Playwright smoke and Screenshot diff to time out at 10
minutes on every PR. This brief plumbs the bypass secret end-to-end
so the wait-action's healthcheck reaches 200.
Per architect Decision A (.convoys/fix-vercel-deployment-protection-in-ci.md):
- preview-smoke.yml + visual-diff.yml: wait-for-vercel-preview's
`path:` input now carries the bypass as a query parameter
`?x-vercel-protection-bypass=${{ secrets.* }}&x-vercel-set-bypass-cookie=true`.
The action only logs the bare targetUrl (verified in action.js:357,360,363)
so the secret stays out of workflow logs.
Per Decision B:
- max_timeout: 600 -> 120. PR #16 evidence shows Vercel previews are up
within seconds of job start; 120s gives ample headroom and surfaces
misconfigurations in ~2 minutes instead of ~10.
Per Decision D (NEW -- surfaced by Boot-the-brief):
- gate: job's Decide step now checks github.event.pull_request.head.repo.fork
FIRST. Forks lack repo secrets, so they would otherwise burn ~4 minutes
per PR on a misleading 401. The fork-check emits `::notice::` and short-
circuits before the existing skip-via-PR-body directive runs.
Forward-compat for adopt-playwright-smoke:
- Both workflows' Playwright/screenshot-capture step now exports
VERCEL_AUTOMATION_BYPASS_SECRET as env. The actual Playwright config
consumes it via extraHTTPHeaders in adopt-playwright-smoke's brief.
BASE_URL stays as the bare \${{ steps.vercel.outputs.url }} (no query
string) so it remains safe to echo.
Verification:
- YAML parses (js-yaml load on both files: preview-smoke jobs [gate, smoke];
visual-diff jobs [gate, visual])
- actionlint not run (binary not installed locally); recommend installing
for future PRs. Future adopt-actionlint convoy could add it to CI.
- No `set -x`, `echo`, `cat`, or `printf` of the secret or bypass URL
in any modified step
- permissions: and concurrency: blocks unchanged (PR #16 contracts preserved)
