Why

The browser e2e ran as a step inside the preview deploy job. That caused three problems:

  • The deploy job, and the preview comment, waited for the whole e2e run.
  • The only way to retry the e2e was to redeploy the preview.
  • Third-party test tooling ran in a job holding the AWS deploy role and every preview secret.

What

  • A new e2e job runs after deploy-pr-preview (only when the seed and smoke test pass). It builds the web and API URLs from the PR number (app-pr-<n> / api-pr-<n>.maple.dev). The deploy job's URL outputs can't be used: GitHub drops a job output that contains any masked value, and some short Infisical values appear in those hostnames.

  • It loads only PREVIEW_SIGNIN_KEY (required) and ANTHROPIC_API_KEY (optional), each fetched by secret-name, so no other preview secret ever reaches the job. It gets no AWS role, its checkout doesn't keep the token, and its permissions are contents: read and id-token: write.

  • Chromium is cached, keyed by the @e2e-dev/web version. The --with-deps apt install is dropped because ubuntu-latest already has the libraries (same approach as ci.yml).

  • No more continue-on-error: a failing e2e now shows as its own red check. It isn't required, so it doesn't block merges.

  • The job condition uses !cancelled(), like the deploy job. The implicit success() fails when ingest-binary two jobs up is skipped, which is always the case on preview:web.

  • "keeps an API-made tiered rule intact through UI edits" now registers only when the preview has Electric sync (MAPLE_E2E_NO_SYNC). It loads the rule over sync, which preview:web doesn't deploy. Before this PR it failed on every web-only preview and passed on full ones, hidden by continue-on-error.

Verification

  • actionlint is clean.
  • The secret extraction was tested locally against a sample KEY='value' file.
  • This PR carries preview:web, so the new job runs against a real preview.

Summary by CodeRabbit

  • CI Improvements
    • Preview browser tests now run in a separate job after a successful deployment and smoke test. Test results are available as an artifact, including when the job fails.
    • The preview’s web and API URLs and smoke-test outcome are exposed as deployment outputs.
  • Documentation
    • Clarified where to find browser test results and how to rerun the tests without redeploying.

The browser e2e ran as a step of the deploy job, so it held the deploy (and the
preview comment) for its whole run, could only be retried by redeploying, and ran
third-party test tooling next to the AWS deploy role and every preview secret.

- New `e2e` job after `deploy-pr-preview`, reading the URLs from its outputs.
- It loads only PREVIEW_SIGNIN_KEY and ANTHROPIC_API_KEY: Infisical exports to a
  file, the two keys move to the env masked, the file is deleted.
- Chromium is cached by the @e2e-dev/web version instead of installed with
  apt deps every run.
- No longer continue-on-error: a failure shows as its own red, non-required check.

🟢 Confidence 8/10 · likely safe to merge
Held at 8 because a warning is open.
1 warning −1 · 1 note · tests not needed · risk low

Moves the preview browser e2e out of the deploy job into its own e2e job that gets the preview URLs as inputs, loads only two Infisical keys and no AWS role. Sound apart from a stale action pin.

  • deploy-pr-preview now exports web_url, api_url and smoke for downstream jobs
  • New e2e job runs Chromium (cached by @e2e-dev/web version) against the seeded preview
  • PREVIEW_SIGNIN_KEY and ANTHROPIC_API_KEY are extracted from an Infisical file export, then the file is removed
  • e2e is no longer continue-on-error, so it reports as its own check

Before merge

  • Manual · On the first live run, confirm the Infisical action writes .e2e-secrets.env where the extraction step reads it ($GITHUB_WORKSPACE/.e2e-secrets.env)

The workflow-level permissions (lines 33-37) apply to this job as well, so a job whose whole point is a small blast radius — it runs PR-authored test code and third-party browser tooling after loading an API key — keeps pull-requests: write and deployments: write.

🟢 Confidence 10/10 · safe to merge
Both earlier findings are fixed at this head; the only open question is the new job's first live run, which CI has not finished.
no findings · tests not needed · risk medium

Moves the preview browser e2e out of the deploy job into its own e2e job that takes the preview URLs from deploy outputs and loads only two Infisical keys. Both earlier findings are fixed; no new defects found in the delta.

  • deploy-pr-preview exposes web_url, api_url and smoke as job outputs
  • New e2e job runs only after a passing smoke test and fails red instead of continue-on-error
  • e2e loads only PREVIEW_SIGNIN_KEY and ANTHROPIC_API_KEY via an Infisical file export, masking each value
  • e2e runs with its own contents: read / id-token: write permissions and no AWS role

Before merge

  • Manual · Confirm ANTHROPIC_API_KEY exists in the pr-preview Infisical environment (slug from PREVIEW_INFISICAL_ENV_SLUG or dev), or the agent.* tests skip
  • Manual · Watch the first live e2e run on this PR's preview; the previous run was cancelled before it executed

Fixed since the last review

What was checked
  • F1 fixed: Infisical/secrets-action is now d2e351f # v1.0.18, the same pin as deploy-setup/action.yml:48
  • F2 fixed: the job-level permissions block replaces the workflow's pull-requests: write and deployments: write
  • A missing PREVIEW_SIGNIN_KEY fails the suite loudly (apps/web/e2e/tests/auth.setup.e2e.ts:13), so secret extraction cannot silently skip

Moves the preview browser e2e out of the deploy job into its own e2e job that runs after a passed smoke test, loads only two secrets and no AWS role, and caches Chromium. Safe to merge.

  • e2e job split out of deploy-pr-preview, gated on the smoke step's outcome
  • Only PREVIEW_SIGNIN_KEY and ANTHROPIC_API_KEY leave the Infisical file export
  • Chromium cached by @e2e-dev/web version; the --with-deps install dropped
  • continue-on-error dropped, so a failing suite is a red check
What was checked
  • apps/web/e2e reads only MAPLE_E2E_APP_URL, MAPLE_E2E_API_URL, ANTHROPIC_API_KEY, PREVIEW_SIGNIN_KEY — all set by the new job
  • ci.yml:272-284 installs Chromium the same way (no --with-deps, ~/.cache/ms-playwright), so the apt step is redundant there too
  • Teardown, failed deploy and fork PRs all leave smoke non-success, so the new job stays skipped

…acked test on preview:web

- Infisical `secret-name` fetches PREVIEW_SIGNIN_KEY (required) and
  ANTHROPIC_API_KEY (optional) into the env, so no other preview secret ever
  reaches the job. Drops the file export, its parsing and its path mismatch.
- The e2e checkout no longer persists the token.
- "keeps an API-made tiered rule intact through UI edits" loads the rule over
  Electric sync, which preview:web does not deploy: it failed on every web-only
  preview and passed on full ones. It registers only when sync exists
  (MAPLE_E2E_NO_SYNC).

Maple review

🟢 Confidence 9/10 · safe to merge
No defects in either diff; the one gap is coverage: the tiered-rule e2e no longer runs on the default preview:web previews.
no findings · tests partial −1 · risk medium

Moves the preview browser e2e out of the deploy job into its own e2e job that loads only two named secrets, gates the sync-dependent alert-rules test on preview:web, and drops continue-on-error. It ran green on this PR, so it is safe to merge.

Fixed since the last review

  • ✅ F3 · Infisical export path is rooted at one step and workspace-relative at the other
What was checked
  • F3's export file is gone: no SECRETS_FILE/filter step remains in .github at the head; both keys use secret-name + export-type: env.
  • Skip rationale holds: the editor resolves ?ruleId= from synced collection rows (apps/web/src/page/alerts/editor/draft.ts:64), absent on preview:web.
  • Chromium cache and the dropped --with-deps mirror ci.yml:272-284, keyed on the e2e engine version.
