PR: #435
reviewed_head: 1c32e36
base: main
source: cheerc/talented-easyorder
scope_source: live repository evidence + decision d-20260812090623041816-47

audit_mode: light sanity review (single reviewer; read-only; exact-head)

Verified conclusions

• .github/workflows/ci.yml now targets main for both push and pull_request; no stale dev branch filter remains.
• .github/workflows/e2e-tests.yml active branch references now use main, including the nightly gh run list --branch main lookup and failure issue text/title. It retains only workflow_dispatch and scheduled execution; no PR trigger was introduced.
• The diff is limited to the two workflow files and changes branch-targeting/comment/report text only. No dev environment or Firebase/Vite configuration semantics were changed.
• Runtime-sensitive workflow behavior is validated by the PR's exact-head CI run 31581694443: build-and-test and e2e both completed successfully.

Findings

None in the assigned scope.

Scope

Audited: .github/workflows/ci.yml, .github/workflows/e2e-tests.yml; push/pull_request branch filters; active E2E main references; environment/config semantic preservation; exact-head PR CI evidence.
Excluded per assignment: product behavior, archived docs, lockfile/devDependencies, historical docs, and unrelated workflow semantics.

Uncertified / blind spots

No product tests were run locally (review is read-only and workflow-focused). This review does not certify behavior outside the changed workflow branch routing and the exact-head CI jobs listed below.
