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

msg = """[笑笑] price_events.json 已彻底退役 — 全系统只认 DB
|
||
|
||
按你的指示，所有和 price_events.json 相关的代码已全部改完：
|
||
|
||
【代码修改（6个文件）】
|
||
1. price_monitor.py — record_event 只写 DB，EVENTS_PATH/load_events/save_events 全部删除
|
||
2. strategy_feedback.py — 价格事件只从 DB 读，JSON fallback 删除
|
||
3. system_health_check.py — 文件检查清单移除 price_events.json，事件统计只读 DB
|
||
4. mo_config.py — 删除无调用的 price_events_path 死属性
|
||
5. mofin_health.py — 新鲜度检查改回读 DB 表（现在它是权威了）
|
||
6. mofin_db.py — 修了一个更大的坑 ⬇️
|
||
|
||
【顺藤摸出的更大的坑：三个数据库】
|
||
mofin_db.py 的 DB_PATH 原来是相对路径（__file__.parent/data），导致每个硬链接副本解析到不同的库：主库、web-dashboard 库、还有 profile 本地一个几乎全空的第三库。健康检查之前读到 0 条事件就是因为读到了那个空库。已改为绝对路径 /home/hmo/MoFin/data，4 份 mofin_db 副本已统一硬链接。
|
||
|
||
【验证结果】
|
||
✅ record_event 只写 DB，JSON 不再被重建
|
||
✅ system_health_check：历史事件 6353 条 / 今日事件 2965 条（之前误报 0/0）
|
||
✅ strategy_feedback / price_monitor 完整跑通
|
||
✅ price_events.json 已归档 trashbox（数据早已全量回填 DB）
|
