Root cause analysis of the 2026-07-20 redundancy incident: 1. No single-source-of-truth rule -> same file legitimately lived in 4+ locations, diverging silently 2. Relative path resolution (Path(__file__).parent/'data') -> each hardlinked copy of mofin_db.py pointed to a DIFFERENT database 3. 'Backup habit' left .bak/legacy files in production dirs, which monitoring then scanned and reported as false alarms 4. Half-done migrations: DB tables created but old JSON writers/readers stayed (price_events), old files stayed 5. Dead modules never got buried: xiaoguo 'dead' but bot ran 8 days as root eating 2.5GB 6. Monitoring checked 'does it exist' not 'is it alive' -> stale file mtime reported as 'pipeline stalled 14 days' (false alarm) 7. No 'system hygiene' as a check category at all Prevention implemented: - dev-spec.md v2.0: 五条红线 -> 十条红线 #6 single source of truth (hardlink only, no independent copies) #7 absolute data paths only (no __file__-relative data resolution) #8 no backups/legacy in production data dirs (archive immediately) #9 dead module burial checklist (6 mandatory steps) #10 monitor liveness (DB table freshness) not existence - File Location Constitution: canonical location per content type - NEW system_hygiene_audit.py: weekly Monday 07:30 cron checking diverged copies / broken hardlinks / zombie processes / orphan data files / dead cron scripts / DB freshness -> hygiene_report.json + XMPP - specs/hygiene.json: module spec per red line #1 - Verified: audit found 5 real issues on first run, all fixed, re-run clean
