Summary
PULL_REQUEST_NUMBER(fromgithub.event.pull_request.number) andFORGEJO_TOKEN(fromsecrets.FORGEJO_TOKEN) to thee2e-browserstep's env block in.forgejo/workflows/ci.yml.e2e/screenshotscope.ShouldPostto post a screenshot to a PR.SCREENSHOT_JOURNEY) remains unset in CI, so the full browser suite never dumps every journey's screenshot onto a PR — a targeted journey run must set it explicitly (seescreenshotscope.ShouldPostand the package-level doc comment for the three-var pattern).PULL_REQUEST_NUMBERis empty on push/main runs, so non-PR CI stays clean — the helper already no-ops when it is empty.FORGEJO_TOKEN secret caveat
One manual step required by the repo owner:
FORGEJO_TOKENmust exist as a repo secret in Forgejo (Settings → Actions → Secrets) with PR-comment write scope. If the secret is absent, the post still no-ops gracefully (no CI failure), but screenshot auto-post will not work until the secret is added.Test plan

[MAJOR] .forgejo/workflows/ci.yml:314-315 — Screenshot auto-post goal not achieved; SCREENSHOT_JOURNEY env var missing
The bead's stated goal ("UI screenshot auto-post stops no-op'ing") requires all THREE env vars: PULL_REQUEST_NUMBER, FORGEJO_TOKEN, and SCREENSHOT_JOURNEY. ShouldPost (e2e/screenshotscope/scope.go:51) gates posting on all three being non-empty:
This PR wires the first two but leaves SCREENSHOT_JOURNEY unset in CI. Without it, shouldPostJourneyScreenshot returns false on every journey, so uploadJourneyScreenshotToPR still no-ops even on PR runs. The comments in the PR even acknowledge this: "without it the full suite never auto-posts even with these two set" — which describes the current state after merge.
For screenshots to actually auto-post on a normal UI PR CI run, SCREENSHOT_JOURNEY must be set to the target journey slug. Current options:
Without one of these, the feature remains incomplete and UI teams still need manual capture + post (same as pre-PR state).

MAJOR fix:
[shot:<slug>]PR title marker now wiresSCREENSHOT_JOURNEYautomaticallyThe code review flagged that wiring only
PULL_REQUEST_NUMBER+FORGEJO_TOKENwas insufficient —screenshotscope.ShouldPosthas a three-var gate andSCREENSHOT_JOURNEYwas never set in CI, so no screenshot ever auto-posted.What changed (commit
03420ebf)A new step "Extract screenshot journey slug from PR title" runs before
make e2e-browser. It parses[shot:<slug>]from the PR title usingsedand writesSCREENSHOT_JOURNEY=<slug>to$GITHUB_ENV. The run step picks it up via${{ env.SCREENSHOT_JOURNEY }}.Convention for UI PRs
Include
[shot:<slug>]anywhere in the PR title — the slug must match the string passed touploadJourneyScreenshotToPRin the journey test:That is all. CI extracts the slug, the three-var gate opens for exactly that journey, and only that screenshot posts to the PR.
Why not a committed file?
A committed
.screenshot-journeyfile would be inherited by every branch subsequently branched frommainand cause stale screenshots from a different PR to be posted on unrelated PRs. The PR title is PR-scoped by design — it never persists tomain.Non-UI PRs / push runs
No

Phase 0: DEMO Verification
N/A — this is a CI/workflow infrastructure fix with no end-user DEMO.
Phase 1: Spec Compliance
Prior MAJOR (from previous review): SCREENSHOT_JOURNEY environment variable was unset, allowing ANY journey's screenshot to post when PULL_REQUEST_NUMBER and FORGEJO_TOKEN were set. This caused cross-PR pollution (PR #776 accumulated 38 stray screenshots).

Phase 2: Code Quality

The MAJOR is RESOLVED. The three-variable gate (
tokenANDprNumANDtargetJourneymatch) is now enforced at the gating function (screenshotscope.ShouldPost), and SCREENSHOT_JOURNEY is populated from the PR title via sed extraction in the CI step — eliminating cross-PR pollution. When a UI PR includes[shot:<slug>]in its title, only that journey's screenshot posts. Non-UI PRs and push/main runs produce no screenshots.REVIEW VERDICT: 0 blocker, 0 major, 0 minor
