# Memory Fixer
## Purpose
Auto-fix low-hanging fruit in the graph. No judgment calls — only deterministic Level 1 operations. Escalate anything that needs Kwame's input.
## Level 0 Auto-Deletes (Allowed Without Approval)
Ephemeral heartbeat and log nodes that violate "Logs NEVER go in the graph":
- `[LITELLM-HEALTH]`, `[GPU-SELF-HEAL]`, `[PM2-SELF-HEAL]`
- `[PROXMOX-MONITOR]`, `[GPU-MONITOR]`, `[INFRA-MONITOR]`, `[AGENT-HEALTH]`, `[DISK-GC]`
- `[WAL]` entries older than 30 days
**Condition:** node must be an orphan (no edges). Deleting a connected node risks breaking other nodes.
**Method:** direct SQLite on `.65` (MCP has no delete tool):
```bash
ssh root@192.168.68.65 "sqlite3 /root/.local/share/RA-H/db/rah.sqlite \"
DELETE FROM nodes WHERE id IN (
SELECT id FROM nodes WHERE id NOT IN (SELECT from_node_id FROM edges)
AND id NOT IN (SELECT to_node_id FROM edges)
AND title LIKE '[LITELLM-HEALTH]%' -- add more prefixes as needed
);\""
```
## Level 1 Auto-Fixes (No Judgment Required)
### 1. Missing `type` Field
For nodes with content but no `metadata.type`:
- Title contains "Proxmox" or "infrastructure" → `type: infrastructure`
- Title contains "skill" or "how to" or "guide" → `type: skill`
- Title contains "doc" or "template" or "brand" → `type: documentation`
- Title starts with "WAL:" or "TASK:" → `type: note`
- Title starts with "[LEARN]" → `type: documentation`
- Otherwise → `type: note` (default)
### 2. Missing `tenant` / `namespace`
For any node with NULL tenant or namespace:
```sql
UPDATE nodes
SET metadata = json_set(
COALESCE(metadata, '{}'),
'$.tenant', 'syslogsolution',
'$.namespace', 'syslogsolution'
)
WHERE json_extract(metadata, '$.tenant') IS NULL
OR json_extract(metadata, '$.namespace') IS NULL;
```
### 3. Staleness State Transitions
Using the type-based windows from the memory-monitor contract:
- Nodes stale > their window → transition to `state: review_pending`
- Nodes in `review_pending` for >7 days → escalate to Kwame (Level 2)
## Level 2 Escalations (Kwame Decision Required)
1. **Nodes in `review_pending` >7 days** — Archive, refresh, or keep?
2. **Orphan Nodes >90 days old** — Delete or Connect?
3. **Potential Duplicate Nodes** — Same title or >70% overlap. Merge or Keep?
4. **Conflicting Metadata** — Content suggests one tenant but metadata says another.
## Logging
Every Level 1 fix logged to `~/.hermes/logs/memory-fixer/YYYY-MM-DD.md`
Every Level 2 escalation logged and delivered to Kwame.
