📝 SummarySummary by CodeRabbit
WalkthroughThe pull request hardens reusable workflows and CI policy checks. It pins Standards checkouts, verifies mirror SSH hosts, validates Hypatia cache commits, rejects invalid workflows, and adds ruleset repair planning with tests and documentation. ChangesCI hardening
Estimated code review effort: 4 (Complex) | ~45 minutes Severity of issue fixed: High Merge Risk: 🟠 High · up to The governance workflow remains vulnerable to mutable helper code and can miss prohibited path checks, so these issues should be fixed before merge. Sequence Diagram(s)sequenceDiagram

Inline comments:
In @.github/workflows/governance-reusable.yml:
- Line 270: Update the stale workflow terminology in
.github/workflows/governance-reusable.yml: at lines 270 and 1254, revise
comments to describe the explicit helper commit pin rather than
job.workflow_sha; at line 1278, update the failure message to use the same
explicit helper-pin terminology. Keep the workflow behavior unchanged.
In @.github/workflows/mirror-reusable.yml:
- Around line 194-214: Extract the duplicated SSH host verification logic into a
local composite action with host and approved-fingerprint inputs, preserving
validation, key scanning, fingerprint comparison, and GIT_SSH_COMMAND setup.
Replace each job’s inline verification block with a single invocation of the
action, and add the corresponding local action reference to this workflow’s
actions.lock entry.
- Around line 86-87: Make the “Verify gitlab SSH host” step advisory-only by
configuring it to continue on error, matching the existing mirror push behavior.
Preserve the current conditional on env.GITLAB_KEY and ensure a failed
ssh-keyscan does not fail the workflow or turn main red.
- Line 147: Update the APPROVED_FINGERPRINT configuration for Disroot so it does
not rely on the unverified hardcoded default: confirm and replace it with an
authoritative git.disroot.org ED25519 fingerprint, or require
DISROOT_SSH_FINGERPRINT to be explicitly provided. Preserve fail-closed SSH host
verification.
In `@docs/MIRROR-HOST-VERIFICATION.adoc`:
- Around line 36-40: Update the documentation paragraph to identify
scripts/tests/science-ci-security-test.sh as the launcher and
scripts/tests/science-ci-security-test.rb as the assertion file containing the
SSH and Hypatia checks.
In `@scripts/check-descriptile-policy.sh`:
- Line 12: Update the detection logic on line 12 to match only actual executed
file-existence tests, excluding quoted descriptive text such as echo statements
containing “test -f” or the retired path. Preserve detection of genuine -f, -e,
and check_file usage, and add a negative test covering the quoted-example case.
In `@tools/policy/check-workflows-parse.sh`:
- Line 55: Update the yq branch of has_no_jobs to require that .jobs is a
mapping while still accepting null or an empty mapping; reject scalar and
non-empty sequence values, and add fixtures covering those cases.

Detect retired paths split across shell quoting.
The scanner misses test -f ".machine_readable"/STATE.a2ml. Shell concatenates these fragments into the retired path, but lines 21-23 discard the quoted prefix because it is not a complete path. Normalise literal fragments within a shell word, or use a shell-aware parser. Add prefix- and suffix-quoted regression cases.

In `@scripts/check-descriptile-policy.sh` around lines 21 - 23, Update the scanner
logic around the quoted-fragment handling in the policy-check script so
shell-concatenated literals such as a quoted directory prefix plus an unquoted
filename are normalized into one path before retired-path matching. Preserve
existing command-substitution and backtick detection, and add regression cases
covering both prefix- and suffix-quoted retired paths.

The SSH mirror work looks good, but there are still two security blockers before I would approve.
First, "hypatia-scan-reusable.yml" still resolves moving Hypatia HEAD on every run and then builds/executes that code with "HYPATIA_SCAN_PAT" or "GITHUB_TOKEN". Checking that the fetched SHA equals the SHA resolved earlier in the same run fixes cache/TOCTOU consistency, but it does not establish trusted provenance: a caller pinned to Standards revision X will execute a new Hypatia revision whenever upstream HEAD advances. Please use a reviewed immutable Hypatia commit, with an explicit bump/review process, as the baseline-validation path already does.
Second, the immutable-helper repair in "governance-reusable.yml" is incomplete. There are still several "standards@main" checkouts whose scripts are subsequently executed, not just the pin-existence gate identified by CodeRabbit. This includes the trusted-base and licence-consistency checks and other shared-script jobs. A pinned reusable workflow therefore still does not imply pinned implementation code; some of these checkouts also retain checkout credentials. Please move executable Standards helper checkouts to the reviewed helper revision consistently.
The current "check-descriptile-policy.sh" quoted-fragment bypass is also valid: shell concatenation such as "".machine_readable"/STATE.a2ml" executes as the retired path but escapes the scanner. Please add prefix/suffix quoted regression cases and fix the normalisation. Since that helper is pinned to "874ffe…", remember to advance the helper pin after fixing it.

Repairs the shared causes behind natsci-studio #82 and fraying-model-computational-testbed #65: Hypatia fetches and verifies its resolved source commit, SSH mirrors verify independently approved fingerprints before pushing, and governance rejects empty job templates and retired descriptile path requirements. Replaces the nonexistent job.workflow_sha context with a reviewed immutable helper commit. Includes negative controls for forged/empty/malformed host keys, an advancing upstream scanner branch, mismatched scanner caches, and contradictory policy checks. Validation: three executable security regression tests pass; actionlint passes on the changed reusable workflows; governance contract and all 14 shape assertions pass. Fixes #762.
