catalog-repair（目录修复）

Purpose

Check and fix consistency of the topics.md index against actual .memory/ files.

Checks

1. Dead links → topics.md references non-existent files → auto-delete (fixed)
2. Missing registration → bucket files not indexed in topics.md → ai_actions
3. Duplicate topics → same topic header appears multiple times → manual_actions
4. Invalid anchors → #anchor not found in target file → ai_actions (if close match) or manual_actions

Required Flow

memory-hub catalog-repair

Output

JSON envelope with:

• data.fixed: auto-fixed items
• data.ai_actions: items AI should self-heal
• data.manual_actions: items requiring human confirmation

Post-Processing

After receiving results:

• ai_actions non-empty → AI executes self-healing (register missing files via memory.index, fix anchors), then runs catalog-repair again to confirm cleared
• manual_actions non-empty → report to user before task ends
