Follow-up to #243. Restoring the deleted lockfile blocks was necessary and not
sufficient: Pages still failed in Set up job with the same annotation.
The dependency list lives on the wrong entry after a re-pin:
'actions/upload-pages-artifact@v5.0.0': # gh actions-lock wrote `uses:` hereuses:
- 'actions/upload-artifact@bbbca2dd…''actions/upload-pages-artifact@fc324d35…': # the workflow names THIS oneref: 'v5.0.0'# no `uses:` — so GitHub found no dependency list and refused the job
Regeneration now copies the uses: list onto every entry describing the same
commit, so re-pinning an action can never separate it from the actions it
resolves at run time.

📝 Summary
Summary by CodeRabbit
Documentation
Updated the CI/CD guide to explain that lockfiles include pins for dependencies used by composite actions, and that rebuilding a lockfile from workflow references alone may omit them.
Bug Fixes
Lockfile generation now retains existing dependency pins and includes dependencies referenced by composite actions. Validation remains consistent with the merged lockfile.
The pinning script now preserves existing dependencies: entries, adds missing entries for workflow action SHAs, and copies composite-action dependency lists between entries for the same commit. The CI/CD guide documents these lockfile requirements and the script’s merge and check behaviour.

The script adds entries for workflow action SHAs and copies composite-action uses: lists between entries for the same commit. The guide documents the lockfile requirements and the script’s merge and --check behaviour.

Merge Risk: Low · up to 3f5d8
The current lockfile is not shown to be broken, but the checks can miss a nested pin that would prevent a Pages job from starting. Address that gap and the parser safeguard before relying on future lockfile regeneration.

…kflow names
The lockfile blocks were restored but Pages still failed in Set up job with the
same message. The reason is which entry carries the dependency list:
'actions/upload-pages-artifact@v5.0.0': <- gh actions-lock wrote `uses:` here
...
uses:
- 'actions/upload-artifact@bbbca2dd…'
'actions/upload-pages-artifact@fc324d35…': <- the workflow names THIS one
ref: 'v5.0.0'
...
The tag-keyed entry had the `uses:` list; the workflow re-pinned to the SHA, so
GitHub resolved the SHA entry, found no dependency list, and refused the job.
Restoring the block was necessary and not sufficient.
Regeneration now copies the `uses:` list onto every entry describing the same
commit, so a re-pin cannot separate an action from the actions it resolves.

- Around line 158-161: Update parse_lock to reject non-blank content under
dependencies: that is not part of a recognised block, rather than silently
ignoring it or attaching it to the previous block. Continue accepting the
current four-space, single-quoted block keys, field lines, uses: lists and their
list entries.
- Around line 285-316: Update the lockfile generation flow in build_lock to
validate every nested reference in preserved `uses:` lists before emitting the
lockfile. Normalise each nested reference to its lockfile key, collect keys
absent from merged, and fail with a clear error listing the missing pins; leave
existing dependency-block generation and emission unchanged.
- Around line 296-298: In the deps_by_commit loop, remove the no-op if/pass
branch and compute block_fields(lines) when retrieving commit. Rename ambiguous
l iterator variables to line in the uses checks, including the later check that
triggers Ruff’s E741 rule.

Validate every nested uses: pin before emitting the lockfile.
build_lock creates dependency blocks only from workflow and local-action references. It preserves a composite action's existing uses: list, but it does not create blocks for nested references in that list. Therefore, --check can accept an unchanged lockfile that is missing a nested pin. The validator has the same gap.
GitHub can then reject the affected job during Set up job with lockfile missing pin for <the nested action>.

Remove the no-op branch and rename the ambiguous variable l.
The if body at lines 297-298 is only pass, so the branch has no effect. The any(...) check at line 297 has no effect either, because the branch never runs its body.
Ruff's default rule set includes E741 (ambiguous variable name). The repository has no Ruff configuration, so the default rules apply to ruff check . in the lint task. That check reports l at lines 297, 300 and 308. Because the task chains commands with ||, a Ruff failure does not fail mise run lint when prettier --check . or black --check . succeeds. The lint task can therefore pass while this violation remains.
block_fields(lines) on line 296 only supplies commit. Compute it at the point of use.
♻️ Suggested fix
deps_by_commit: dict[str, list[str]] = {}
for lines in merged.values():
- fields = block_fields(lines)- if "uses" in fields or any(l.lstrip().startswith("uses:") for l in lines):- pass
try:
- idx = next(i for i, l in enumerate(lines) if l.strip() == "uses:")+ idx = next(i for i, line in enumerate(lines) if line.strip() == "uses:")
except StopIteration:

deps_by_commit.setdefault(commit, lines[idx:])

Fail on unrecognised dependency-section lines.
parse_lock recognises only four-space, single-quoted block keys. A different block-key layout can be absorbed into the previous block, or ignored before the first recognised block. The rebuilt lockfile can then lose a dependency block or associate its uses: list with the wrong entry.
Add a clear error when dependencies: contains non-blank content that does not belong to a recognised block. Allow the current format, including field lines, uses: lists, and their list entries.
