5 YAML pattern files (role-override, instruction-injection, exfiltration, jailbreak, encoding) with 30 patterns total. Embedded at compile time via include_str!. External pattern directory support for community extensions. 7 pattern loading tests. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Pre-compiles all pattern regexes once before scanning (not per-line). Supports per-line suppression via allowlist integration. Includes 6 scanner tests with clean and injected fixtures. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Per-line suppression via HTML comments (<!-- injection-scanner:ignore PI001 -->). Supports multiple IDs per line. Suppression is pattern-specific: suppressing PI001 does not suppress PI011 on the same line. 9 allowlist tests. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Text reporter: per-file findings with line numbers, severity, message, remediation, pattern ID, and summary counts. JSON reporter returns Result<String, serde_json::Error> for precise error handling. 7 reporter tests. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
