 ## 2026-06-14 - Deferring Pathlib Operations in Hot Paths
 **Learning:** In highly repetitive loops like file scanners (e.g., iterating through thousands of safe files), preemptively calculating `Path.relative_to()` and sanitizing strings adds significant cumulative overhead. Pathlib operations internally parse paths, check parts, and construct new objects, which is extremely expensive when executed on a per-file basis unconditionally.
 **Action:** Always defer expensive path computations (like converting paths to relative or string sanitization) until *after* the fast-path condition (like a regex match) triggers. This drastically cuts down on unnecessary string operations for clean files.
+
+## 2024-06-16 - Optimizing tight loops with pre-extracted tuples
+**Learning:** In python tight loops, checking `rule["search"](line)` on a list of dictionaries requires a dictionary lookup (`__getitem__`) on every iteration which introduces unnecessary overhead. While `tuple(applicable_rules)` is fast to iterate, we can extract the function and avoid dict lookup.
+**Action:** In `_scan_file`, cache `applicable_rules` as a tuple of `(search_function, rule_dict)` tuples and use tuple indexing (`tup[0](line)`) to invoke the function. Also, `open(file_path)` is marginally faster than `file_path.open()`.

 **Vulnerability:** The CLI file scanner `vibesec scan` lacked detection rules for fundamental security vulnerabilities in JavaScript/TypeScript ecosystems, specifically arbitrary code execution via `eval()` and Cross-Site Scripting (XSS) via React's `dangerouslySetInnerHTML`.
 **Learning:** Even specialized "vibe-coding" static analysis tools must include detection for standard, catastrophic security anti-patterns (like eval and XSS injection vectors) to provide complete coverage.
 **Prevention:** Two new rules, `dangerous-eval` and `react-dangerously-set-inner-html`, were added to `SCAN_RULES` to flag these patterns.
-## 2025-02-12 - Prevent ReDoS by avoiding capturing groups in scanner rules
-**Vulnerability:** Regular Expression Denial of Service (ReDoS) vulnerability caused by tracking capturing group matches `(...)` during line-by-line file scanning in `SCAN_RULES`.
-**Learning:** In a highly repetitive inner loop (line-by-line file scanning), tracking backreferences and capturing group matches incurs unnecessary regex engine overhead. While unbounded quantifiers are the primary ReDoS cause, capturing groups exacerbate the tracking state, increasing scan time significantly on long lines or adversarial payloads.
-**Prevention:** Always use non-capturing groups `(?:...)` instead of capturing groups `(...)` when adding or modifying regular expressions in `SCAN_RULES` to prevent unnecessary performance overhead and ReDoS vulnerabilities.

-## 2026-06-16 - Add OWASP mapping and pre-commit hook integration
-**Vulnerability:** The VibeSec scanner lacked explicit mapping to standard vulnerability frameworks (like OWASP Top 10) and relied on manual invocation, meaning vulnerabilities could easily bypass detection and be committed by developers or AI agents (like Claude Code or Codex).
-**Learning:** To enforce security guardrails effectively, static analysis tools should intercept the workflow at commit time. Mapping findings to OWASP categories improves the clarity and actionability of the scanner output.
-**Prevention:** Updated `SCAN_RULES` messages to include relevant OWASP classifications (e.g., A01, A03). Added a `vibesec hook` command that automatically installs a `pre-commit` script to block commits if critical or high vulnerabilities are detected.
