ci: float setup-soldr at v0 (v0.9.82 Dylint cache fixes)

[zackees]

Tracking: zackees/ci.yml#31. Reference: zackees/kernal-api#368.

Floats every zackees/setup-soldr use at @v0 (currently v0.9.82, a07bab94f16124b5c6857b137a237a53a61e06d1).

Old pins: v0.9.62 (_build, _unit-test, _integration-test, _terminal-test, linux-x86-dwarf-smoke, linux-x86-render-smoke), dfbe9627f6cb0226716b61625b99a58949162720 # v0.9.80 (_lint), bb28e96d2dc32c058242f56722297caf1efcbd90 (macos-arm-live-test, macos-x64-guest-webkit-probe)

Reason: v0.9.82 includes setup-soldr#539 and #541. Without them a successful Dylint run never saves dylint-cache / dylint-output-cache ("no matching successful Dylint marker - skipping save"), so every Dylint run is cold. Floating v0 picks up future fixes in the same major.

Updates tests/unit/test_ci_modes.py anchors from @v0.9.62 to @v0. Local: 17 passed, 1 failed (test_platform_workflows_have_normalized_tiers on macos-arm-lint.yml), which fails identically on main and is unrelated.

Summary by CodeRabbit

• Chores
  • Updated automated build, lint, and test workflows to use the v0 setup-action reference.

📝 Walkthrough

Walkthrough

Nine CI workflows now use the floating zackees/setup-soldr@v0 action reference instead of pinned versions or revisions. The unit test now locates setup steps by the v0 action prefix.

Changes

Soldr action references

Layer / File(s)	Summary
Update workflow action references .github/workflows/*, tests/unit/test_ci_modes.py	The workflows use the floating v0 action reference. The unit test matches the updated reference; its version-selection assertions remain unchanged.

Priority: ➖ Normal

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

Change: Other

Merge Risk: 🔵 Low · up to fc208

CI now always pulls the latest v0 release of the Soldr setup action. This picks up the Dylint cache fixes automatically, but future action updates will also run without review. The change is mergeable if the maintainers accept that tradeoff; otherwise, pin the full commit SHA where the workflows previously used one.

Security Architecture Review

Security architecture risk: 🟠 High · up to fc208

A moving action tag lets future action updates run across build and release jobs without a corresponding change to this repository. Those jobs produce published binaries and wheels, and release builds may expose a token with write permissions to the action.

Retained concerns

• High · security · inferred: The moving action runs in release build jobs that inherit write-capable workflow permissions and explicitly pass it GITHUB_TOKEN. This increases the external action publisher's ability to change code executed with that authority without a repository workflow change; the token handoff itself predates the PR.
• Medium · security · inferred: Future v0 revisions can change the setup code preceding builds and the artifacts subsequently tested or published, independently of the verified repository SHA. The commit-pinned macOS ARM action becomes moving, while the reusable build's existing version tag becomes a broader moving major tag.

Security review details

Security Blast Radius

• inferred — The independently changing external tag is trusted by nine changed CI workflows and, through the reusable build, by six release build jobs. Directly evidenced outcomes include CI workspace execution, test artifacts, release wheels and binaries, and exposure to each job's workflow token; exposure beyond those jobs depends on their effective permissions.

Security Findings and Attack Paths

• inferred — If an attacker can alter the external v0 tag or its resolved code, an eligible CI run can execute that code at setup time with the supplied token and influence later build outputs. The retained finding covers the changed macOS ARM action reference; no evidence establishes that the currently resolved action is malicious.

Trust Boundaries and Controls

• observed — Checkout SHA verification protects the selected repository source, and successful-build gates protect release ordering. Neither control pins the external action. The macOS x64 probe has explicit read-only contents permission, while release builds are invoked beneath a workflow declaring contents and pull-requests write permissions.

Resilience and Maintainability Implications

• inferred — The unchanged macOS ARM producer/consumer ordering and required-artifact failure check contain some partial failures. They do not authenticate artifact contents or make a repeat run use the same action code. The release preflight similarly checks artifact structure rather than its producer identity.

Hardening Proposals

• proposed — Resolve the desired Soldr action release to a reviewed full commit SHA and advance it deliberately; this retains the cache fix without accepting subsequent tag moves automatically.
• proposed — Explicitly narrow permissions on release build caller jobs and other action-running jobs to the minimum they require, separately from jobs that tag or publish. Verify the resulting effective token permissions before relying on this separation.

Both workflows replace reviewed commit pins with a mutable action tag.

If the upstream v0 tag moves or its release account is compromised, later runs will execute unreviewed action code. GitHub identifies a full-length commit SHA as the only immutable action reference. (docs.github.com) The ARM workflow passes GITHUB_TOKEN and builds artifacts; the x64 workflow runs the action before its build. Restore the reviewed SHA at both sites or use reviewed SHA-update automation.
