+# 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.
