Fixes #183. Users with large Codex session directories (45 GB, 10K+ files) experienced CPU pegging because every 30-second refresh re-parsed all session files from scratch. Three optimizations: 1. readFirstLine now reads 16 KB via fs.open() instead of loading the entire file through readSessionFile. Cuts discovery I/O from ~45 GB to ~160 MB for 10K files. 2. Per-file result cache (codex-results.json) with mtime+size fingerprinting. Parsed results are cached on first run; subsequent runs return cached data instantly for unchanged files. 3. Cache-accelerated discovery skips header validation for cached files, pulling the project name directly from the cache manifest. Cache safety: fingerprint captured before read (no TOCTOU), atomic write via temp+fsync+rename, 0o600 permissions, Object.hasOwn for prototype pollution defense, eviction of deleted files on flush, try/finally ensures flush even on parse errors. |
