Cuts the Chromatic builds that rebuild every story without need. Since the Oct 20 reset, 14 of Angular's 24 builds were full rebuilds (68% of its snapshots).
Changes
Merge build (angular-release.yml): before publishing, fetch the commits of the merged PR's Chromatic builds: the chromatic-sha marker, every commit a force-push replaced (from the PR timeline) and the PR head. Without them Chromatic logs Missing commit detected, falls back to an old build and rebuilds everything. Checked against the four stale rc builds from Oct 22 to Oct 29: the missing commit is in the fetched set every time.
Approval build (angular-chromatic.yml):
skip the build when the PR changes .storybook/, a file preview.tsx imports, or an @angular/ or @storybook/ version, because each forces a full build and the rc build repeats it anyway; a comment says so and points to the manual run
fetch the commits of the PR's earlier builds before publishing
read all PR comments, not just the first page, and only trust chromatic-sha markers from the workflow's own comments (shared with the merge build in .github/scripts/chromatic-baseline.cjs)
chromatic.config.json: untrace the public barrels (src/tedi/index.ts, src/tedi/components/index.ts, src/community/index.ts). Today about 135 snapshots recapture on every TurboSnap build through them.
text-group and status-indicator stories: deep imports instead of the barrels.
Behaviour-only stories with snapshots disabled:KeepOpenOnSelect in dropdown (closed trigger only). ClearButtonOnInteraction in search, select and form-field stays snapshotted: the hidden clear button uses visibility: hidden, so it keeps its space at rest (and select also makes the separator transparent), which no other story shows. Search's "no visible label" story stays snapshotted too, because it is a real visual variant.

only still-valid issues, skip the rest with a brief reason, keep changes
minimal, and validate.

Review comments at @.github/workflows/angular-chromatic.yml:
- Around line 58-65: Update the Checkout step to read `.github/scripts` from the
pull request’s base branch rather than its approved head, so older PR branches
can use the repository-local helper. Add the required `contents: read`
permission while preserving the existing checkout settings.
Walkthrough
The Chromatic workflows now collect prior build and force-push commits, fetch available baselines, and avoid selected redundant approval builds. The PR also updates dependency tracing and Storybook imports, disables one snapshot, and paginates comment lookups.
Changes: Chromatic workflow and story updates
Layer / File(s)
Summary
Tracing and Storybook snapshot inputs chromatic.config.json, src/tedi/components/content/text-group/text-group.stories.ts, src/tedi/components/tags/status-indicator/status-indicator.stories.ts, src/tedi/components/overlay/dropdown/dropdown.stories.ts
The untraced list adds three source entry points. Two stories switch to direct component imports. KeepOpenOnSelect disables Chromatic snapshots.
The helper paginates comments, collects valid bot-comment build markers, and adds commit OIDs from pull-request force-push events. It warns and continues if force-push history retrieval fails.
Approval build guard and baseline fetching .github/workflows/angular-chromatic.yml
The guard uses the shared baseline helper, skips already-built heads and selected full-build cases, and posts a marked notice when needed. The workflow fetches available prior commits and paginates build-result comments.
Release baseline discovery and fetching .github/workflows/angular-release.yml
The release workflow finds the pull request associated with the release commit, collects baseline SHAs, and attempts to fetch the pull-request head and prior commits. Comment lookup now paginates results.

Full details: Title check
Explanation
The title names the CI change, the Chromatic TurboSnap baseline fix, and the skipping of redundant builds, which match the workflow, script, and story changes in the summary. It is specific and accurate. It cites #824 (the linked issue number) while the objectives cite PR #827, a minor inconsistency that does not affect the title's relevance.
Full details: Linked Issues check
Explanation
Issue #824 is the only direct linked issue, so its coding requirements apply. The reviewed head implements each one:
Baseline fetch [#824]: angular-release.yml (chromatic job) fetches the commits from chromatic-sha markers and the PR head before publishing. angular-chromatic.yml has a Fetch the commit of the previous build step before Publish to Chromatic. Both read comments with pagination through the shared helper .github/scripts/chromatic-baseline.cjs.
Approval skip [#824]: the guard job in angular-chromatic.yml returns build: no when the PR changes .storybook/**. It posts a skip notice and does not repeat it. workflow_dispatch still returns build: yes (verified in the workflow file).
Barrels and deep imports [#824]: chromatic.config.json adds src/tedi/index.ts, src/tedi/components/index.ts, and src/community/index.ts to untraced. text-group.stories.ts and status-indicator.stories.ts use deep imports.
Snapshot settings [#824]: dropdownKeepOpenOnSelect gains chromatic.disableSnapshot. The issue requires snapshots to stay for search, select, and form-fieldClearButtonOnInteraction, and for searchAccessibilityNoVisibleLabel. None of these story files appears in the changed-file summary, so their snapshots remain.
The previous FAIL is withdrawn. It required disableSnapshot on AccessibilityNoVisibleLabel. #824 states that this story keeps its snapshots, so the requirement was misread.
Post-merge verification steps (no Missing commit detected, Inherited via TurboSnap > 0) are not coding requirements and are not assessed.
Full details: Out of Scope Changes check
Explanation
Every changed file maps to #824 or supports its objectives:
.github/workflows/angular-release.yml and .github/workflows/angular-chromatic.yml: baseline fetch, pagination, and approval skip logic.
.github/scripts/chromatic-baseline.cjs: shared helper that reads only github-actions[bot]chromatic-sha markers and adds force-push commits. It supports the fetch step.
chromatic.config.json: the three barrels from #824.
text-group.stories.ts and status-indicator.stories.ts: deep imports from #824.
dropdown.stories.ts: KeepOpenOnSelectdisableSnapshot from #824.
The approval skip also covers changes to files preview.tsx imports and @angular/ or @storybook/ version changes. #824 names only .storybook/**. These extra conditions serve the same goal: they avoid paying for a full build twice. #824 also names dependency changes as full-build causes. They are related, not unrelated changes.

Restrict and bound comment-derived SHAs.
The legitimate chromatic-sha: marker is posted by the GitHub Actions bot from .github/workflows/angular-chromatic.yml. The release workflow accepts the marker from every PR comment, so any commenter can add valid markers.
A sufficiently large set can exceed Linux’s per-string environment limit for SHAS. The fetch step can then fail before its shell starts. continue-on-error: true allows the release to continue, so Chromatic may use an older baseline and capture extra snapshots.
This is a minor workflow availability and quota issue, not a major security issue. Restrict markers to the trusted bot and cap the comment-derived SHAs before setting SHAS.

Update the comment-derived SHA collection around the c.body marker-matching loop
to accept markers only from the trusted GitHub Actions bot identity used by
angular-chromatic.yml, and cap the collected unique SHAs before setting SHAS so
the environment value remains within the platform’s limit.

untraced also stops TurboSnap from tracing through this file. Community components import TEDI through @tedi-design-system/angular/tedi, which maps here, so e.g. a TEDI Button or Icon change no longer re-tests the community Search or FileDropzone stories. They get copied from the baseline. Could src/tedi/index.ts come out of untraced?

It was considered and it's a deliberate trade-off here. Untracing the barrels is what removes the roughly 135 snapshots that were recaptured on every TurboSnap build, whatever the PR changed. Community stories are still recaptured when community files change and on full builds.

This only checks .storybook/, but the note at line ~221 says a dependency change or a preview.tsx import also forces a full rebuild. preview.tsx imports theme.service and the token files, so a PR touching those, or bumping a dependency, still pays for two full builds. Should the check cover them too?
- Read chromatic-sha markers only from the workflow's own comments, via a
shared script both workflows require
- Paginate the sticky comment lookups
- Also skip the approval build for changes to files preview.tsx imports
and for @angular/ or @storybook/ upgrades
- Say the rc build comments only when it finds visual changes
- Keep ClearButtonOnInteraction snapshots: the hidden clear button keeps
its space at rest, so the layout differs from the base story

Check out the base branch instead of the approved head.
After this workflow lands, an older approved PR can still have a head that predates .github/scripts/chromatic-baseline.cjs. The guard then fails at require, so the approval build is skipped.
Use the base branch for this repository-local helper. Grant the checkout its required read permission.
