ci: canary setup-soldr 66c33b0 exact SHA -- not for merge

[zackees]

Canary only (not for merge) for promoting zackees/setup-soldr@v0 to 66c33b01e682c4dbe3869c2adffd9d55f16a7d67 (current setup-soldr main: zackees/setup-soldr#554, #558, #560, #561). Same shape as #1580: every setup-soldr pin set to the exact candidate SHA, on fbuild main 70e08e3. Labeled ci-full so full / Full coverage runs, which setup-soldr's update-v0-tag.yml gate requires. (Earlier commit canaried 3b3a716: run 37044298475, green.)

Summary by CodeRabbit

📝 Walkthrough

Walkthrough

Workflow files and the workflow renderer now pin zackees/setup-soldr to commit 66c33b01e682c4dbe3869c2adffd9d55f16a7d67 instead of prior tags or commit references.

Changes

setup-soldr action pinning

Layer / File(s)	Summary
Update setup-soldr action pins .github/workflows/*, ci/render_workflows.py	Workflow action references and the render_fbuild_bin_job output now use commit 66c33b01e682c4dbe3869c2adffd9d55f16a7d67.

Priority: ⬇️ Low

Estimated code review effort: 1 (Trivial) | ~5 minutes

Change: Other

Merge Risk: 🟡 Moderate · up to 499bf

Restore the approved references or update the repository policy before merging the candidate action pins.

Security Architecture Review

Security architecture risk: 🔵 Low · up to 499bf

The fixed commit reduces exposure to a moving action tag, and no new workflow permissions or execution paths were identified. However, the candidate action also runs in privileged release builds; its credential handling and cache recovery behavior have not been fully compared with the previous revisions.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

• inferred — Compromise of the selected action could affect shared board-build executables and native release artifacts, with downstream GitHub Release and PyPI distribution exposure. Publication runs in separate gated jobs. No such compromise or access to an external cloud account is established.

Trust Boundaries and Controls

• observed — Full CI validates an exact candidate SHA and the actual checkout. The shared fbuild producer disables persisted checkout credentials and requests cache saving only on main. These caller controls remain unchanged; they do not independently constrain all token access available to an action or prove that the action honors its cache inputs.

Resilience and Maintainability Implications

• observed — The shared producer and standalone template retain the fbuild-rust-debug cache suffix and main-only save request. Restoring the prior action reference therefore does not itself demonstrate isolation from candidate-produced cache state; action-level keys, compatibility, concurrency and cleanup remain unverified.

Hardening Proposals

• proposed — Before promotion, compare the candidate action's credential use and cache lifecycle with the previously selected revisions, including concurrent saves, cancellation and rollback compatibility. Confirm the authoritative promotion gate rather than relying solely on the canary description.

Restore the candidate pins to the policy-approved action reference.

.github/workflows/README.md:124-131 permits an action-level canary only for the full board template and requires the documented reference to remain at @v0 otherwise. The PR changes multiple workflows to candidate SHA 66c33b01e682c4dbe3869c2adffd9d55f16a7d67. A canary or not-for-merge status is not a documented repository exception.

If merged, the affected jobs will run the unpromoted candidate action commit instead of the stable @v0 action reference. Restore @v0 for the changed call sites, or update the README policy before merging.

Suggested fix

-        uses: zackees/setup-soldr@66c33b01e682c4dbe3869c2adffd9d55f16a7d67
+        uses: zackees/setup-soldr@v0

Apply this replacement to the changed non-exception call sites, including acceptance-205.yml, template_native_build.yml, and the CI, benchmark, platform, and check workflows. Keep an action-level canary only when it uses the documented full-board-template exception.

Canary served its purpose: run 37058102658 was the evidence for promoting setup-soldr v0 to 66c33b0 (https://github.com/zackees/setup-soldr/actions/runs/37061368573). Closing, not for merge.
