- Line 713: Update the pattern-matching flow for the bun install rule around the
regex at line 713 to remove YAML comments before evaluating commands, while
preserving # characters inside quoted scalars. Ensure trailing comments cannot
satisfy the frozen-lockfile check or create false bun install matches, and add
regression coverage for both cases.

…rived rule `Hypatia.Rules.CicdRules.scan_content_patterns/1` is a complete glob+regex per-line content-rule engine over a `@blocked_patterns` table — supporting `applies_to` globs, `path_allow_prefixes`, `exception`/`exception_repos`, `negative: true` absence rules and inline `# hypatia:ignore <rule_id>` pragmas — and it emits line-anchored findings. It had no caller anywhere in `lib/`; its only reference was its own test file. This wires it in. H1 adds a `:content_patterns` entry to `@all_rule_modules` with a normalization branch in `Hypatia.CLI.collect_findings/2` that carries `line:` through to the finding map, so SARIF gets a real `startLine` rather than the degenerate fallback of 1. H2 adds the first scanner-derived rule as a table row rather than a module: `--frozen-lockfile` enforcement in CI, the one piece of advice flagged independently by both CodeRabbit and Codacy across the estate. Matching runs over comment-stripped content, so a commented-out install line does not fire. H3 covers all three with tests: a positive case, an explicit negative proving the canonical fix is not flagged, and a comment-only case. Not encoded: Codacy's "switch to a commit SHA" advice, which contradicts the standing ruling that `sha_pinning_required` is off and `actions.lock` is the pin. Scanner advice is input to triage, not a rule. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

with “--” as comments for the workflow YAML rule; retain the valid “#” and “//”
markers and ensure long-option lines are still scanned for matches.
- Line 845: Update scan_content_patterns/1 to enumerate repository files once,
pruning .git during traversal, and pass the resulting relative-path list into
each content rule instead of having matching_files/2 call Path.wildcard/2 per
rule. Preserve existing rule matching behavior while eliminating repeated
directory walks and post-traversal .git filtering.

All findings in this review are incorporated: content_patterns appears in both help lists, and YAML comments cannot supply or conceal the frozen-lockfile flag. Verified against current code and 18 passing content-scanner tests.

Activates a rule engine that was already written and had no caller in
lib/.The finding
Hypatia.Rules.CicdRules.scan_content_patterns/1(lib/rules/cicd_rules.ex:793) is a complete glob + regex, per-line content-rule engine over a@blocked_patternstable. It supportsapplies_toglobs,path_allow_prefixes,exception/exception_repos,negative: trueabsence rules and inline# hypatia:ignore <rule_id>pragmas, and it emits line-anchored findings.Its only reference anywhere was its own test file. Verified with a control:
check_repo_requirements, found by the same grep style, is wired atcli.ex:478.The consequence is that authoring a new rule meant writing a module. With this wired, it means adding a table row.
What changed
H1 — wiring.
:content_patternsadded to@all_rule_modules, with a normalization branch inHypatia.CLI.collect_findings/2. The branch carriesline:through, soHypatia.SARIF.render/2gets a realstartLineinstead of the degenerate fallback of1.H2 — first rule, as data.
--frozen-lockfileenforcement in CI files — the single piece of advice flagged independently by both CodeRabbit and Codacy across the estate, mechanical to fix and consistent with estate lockfile doctrine. Matching runs over comment-stripped content.H3 — tests. Positive case; explicit negative proving the canonical fix is not flagged; comment-only case proving a commented-out install line does not fire.
Deliberately not encoded
Codacy posts
🔴 HIGH RISK: switch to a commit SHA to ensure the action is immutable. That contradicts the standing ruling thatsha_pinning_requiredis off andactions.lockis the pin. Encoding it would automate a ruling violation across the estate. Scanner advice is input to triage, not a rule.Gates
