Uses source-aware patterns from git-pkgs/gitignore#35 to detect changes in sensitive ignore policy. Records the matching rule, source, and line for a bounded set of credential, environment, key, and certificate paths.

Summary by CodeRabbit

• New Features
  • Added local detection of ignore rules that may exclude credential, database, environment, private-key, secret, and state-file paths. Results identify matching patterns and their locations.
  • Reports invalid patterns and when an ignore file is too large to inspect, making coverage limitations visible.
  • Refreshes results when project ignore files change and during eligible full scans.
• Documentation
  • Updated the README with details about sensitive-ignore detection, scan behavior, and locally parsed evidence.

Walkthrough

The change adds a local detector that checks project .gitignore rules against sensitive-path candidates. It emits signals for matching and invalid patterns, applies scan-selection rules, and documents the detector.

Changes: Sensitive ignore detection

Layer / File(s)	Summary
Pattern loading and matching detector.go, go.mod, sensitive_ignores.go, sensitive_ignores_test.go	The detector checks credential, database, environment, private-key, secret, and state-file candidates against project ignore rules. It reports matching patterns and source locations, invalid patterns, and coverage signals for oversized files or truncated scope discovery. Tests check signal contents and file-size handling.
Scan selection and signal updates local.go, sensitive_ignores.go, sensitive_ignores_test.go, README.md	The local scan flow selects the detector for forced scans, prior detector errors, or relevant .gitignore changes. It records run status and duration, handles errors, and replaces signals on success. Tests check change filtering and signal-log updates. The README documents the detector, its scan behavior, and the dependency.

Review details

Systems and components

• observed — detector.go (service) was modified; 1 changed file maps to changed impact.
• observed — local.go (service) was modified; 1 changed file maps to changed impact.
• observed — go.mod (service) was modified; 1 changed file maps to changed impact.
• observed — README.md (service) was modified; 1 changed file maps to changed impact.

Before / after behavior

• observed — Modified behavior in sensitive_ignores.go: Adds package imports and constants defining sensitive-ignore categories, a 10,000-scope limit, and a 1 MiB ignore-file size limit.
• observed — Modified behavior in sensitive_ignores.go: Adds the candidate path table mapping credential, database, environment, private-key, secret, and state categories to paths checked against ignore patterns.
• observed — Modified behavior in sensitive_ignores.go: Adds signal generation that loads ignore patterns, reports ignored candidates and invalid patterns, adds a coverage signal when scope discovery is truncated, then sorts and deduplicates the signals. Loading errors are returned.
• observed — Modified behavior in sensitive_ignores.go: Adds recursive .gitignore loading. Excluded directories and files are skipped; files larger than 1 MiB produce an oversized-ignore-file coverage signal without being read. Other read and walk errors are returned. The root scope is included, discovered scopes are capped at 10,000, and new scopes beyond that cap set the truncation flag.

Full details: Title check

Explanation

The title "Detect sensitive ignore policy" matches the main change. The PR adds a Sensitive-Ignore detector that scans .gitignore files for sensitive-file patterns (credentials, databases, environment files, private keys, secrets, and state files). It also reruns when a project .gitignore changes. The title is short, specific, and uses no vague terms.

Full details: Docstring Coverage

Explanation

Docstring coverage is 0.00% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff with cyclomatic complexity of at least 2. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 9 functions across 4 files. (1 skipped: 1 unsupported.)

Resolution

Write docstrings for the functions missing them to satisfy the coverage threshold.
