Merge Risk: 🔵 Low · up to RE001 can incorrectly warn on commented secret text and jobs that quote a valid Harden-Runner reference. This does not affect workflow execution, but reduces the reliability of egress-monitoring findings and should be corrected before relying on the updated rule. 🚥 Pre-merge checks | ✅ 5✅ Passed checks (5 passed)

installs_harden? checks to scope all three values to the containing job rather
than the entire workflow, so only the same job’s runner and hardening state can
trigger the finding. Add a regression test covering a workflow with both
reusable and local jobs, where the reusable job passes a secret without
triggering RE001 because the unrelated local job is not involved.

the research extension rule to restrict runs-on matches to direct job-field

Preserve detection of valid local runner configuration and actual Harden-Runner

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Recognise quoted Harden-Runner references.
This regex accepts only an unquoted uses: value. A step such as - uses: "step-security/harden-runner@<sha>" is a YAML string but does not match. installs_harden? then becomes false and RE001 reports a warning for a hardened job.
Allow an optional single or double quote before step-security/harden-runner@. Add coverage for quoted values.

197-200: RE001 still fails the quoted-use and nested-value cases.Line 200 requires
uses:to be followed immediately bystep-security, so quoted Harden-Runner values leaveinstalls_harden?false. Both quoted cases intest/research_extensions_test.exswill report RE001.Lines 197 and 200 also scan arbitrary indented job text. A multiline
run:orenv:value containingruns-on:or- uses:changes the result, although it is not job configuration or a step. Scope these checks to direct job fields and actual step entries.

RE001 emitted file-wide findings without a source line. GitHub attached those warnings to line 1, so adding the native action-lock header made pre-existing egress-monitoring gaps appear to be new PR defects. The rule also asked reusable-only callers to install steps even though the called workflow owns the runner.
Anchor findings to the actual secret reference, ignore commented configuration when testing applicability, and leave reusable-only callers to the source workflow's scan. Keep warning severity and retain findings on workflows that execute locally. Use the immutable Dependabot actor ID for the existing trust condition and consume the shared workflow contract that recognizes Hypatia's
warnseverity.Validation: 39 research-rule and CLI/SARIF integration tests pass, including a real secret reference, commented hardening as a negative control, reusable-only callers, and the source line surviving through CLI normalization into SARIF. Related consumer repairs: natsci-studio#82 and fraying-model-computational-testbed#65; shared contract: standards#764.
