# Memory Fixer

> **Canonical copy:** `/root/.hermes/contracts/memory-fixer-v3.md` (used by the `memory-fixer-daily` cron job). This file is the institutional record of the same contract. When the two diverge, treat the v3 source in `/root/.hermes/contracts/` as executable truth.

## Purpose
Auto-fix low-hanging fruit in the graph. No judgment calls — only deterministic Level 1 operations. Escalate anything that needs Kwame's input. When Kwame replies to an escalation, **execute the decision to completion** (update state and timestamps), never leaving a node in review-pending forever.

**Type:** Write-only (Level 1 fixes only)
**Scope:** RA-H OS knowledge graph (192.168.68.65)
**Schedule:** Daily at 8 AM ET
**Escalation:** Level 2+ to Kwame as task items

## Key Design Decision

The `updateNode` tool's `metadata` field performs a **restricted merge** — the `state` key only accepts `'processed'` or `'not_processed'`. Additionally, new metadata keys cannot be added via the merge.

**Solution:** Use the `description` field to tag stale nodes with review actions, since `description` is a simple string overwritable via `updateNode`.

**Tag Format:** `[REVIEW: action] original description text...`

Where `action` is one of:
- `archive` — node is stale and should be archived
- `refresh` — node is stale and should be refreshed (infrastructure)
- `keep` — node has been confirmed as current
- `merge` — node is a duplicate candidate

**Query for finding review-tagged nodes:**
```sql
SELECT id, title, description
FROM nodes
WHERE description LIKE '[REVIEW:%';
```

## Level 1 Auto-Fixes (No Kwame Decision Needed)

### 1. Missing `type` Auto-Classification

```sql
SELECT id, title,
  CASE
    WHEN title LIKE '%infrastructure%' OR title LIKE '%proxmox%' OR title LIKE '%setup%' THEN 'infrastructure'
    WHEN title LIKE '%skill%' OR title LIKE '%how to%' OR title LIKE '%guide%' THEN 'skill'
    WHEN title LIKE '%doc%' OR title LIKE '%template%' OR title LIKE '%brand%' THEN 'documentation'
    WHEN title LIKE 'WAL:%' OR title LIKE 'TASK:%' THEN 'note'
    WHEN title LIKE '%[LEARN]%' THEN 'documentation'
    ELSE 'note'
  END as auto_type
FROM nodes
WHERE json_extract(metadata, '$.type') IS NULL;
```

### 2. Missing `namespace` Auto-Population

```sql
SELECT id, title, json_extract(metadata, '$.tenant') as tenant
FROM nodes
WHERE json_extract(metadata, '$.namespace') IS NULL;
```

### 3. Staleness Review Tagging

Using the type-based windows from the memory-monitor contract, tag nodes stale beyond their window. **Only process a maximum of 10 nodes per run** to avoid overwhelming Kwame. Prioritize infrastructure first, then dynamic, then ephemeral.

**Exclusion Rules:**
- Nodes with `state` = `review_pending`, `deprecated`, `archived`, or `not_processed` are NOT processed
- Nodes whose `description` already starts with `[REVIEW:` are NOT re-processed

```sql
SELECT id, title, json_extract(metadata, '$.type') as node_type,
  CAST(julianday('now') - julianday(updated_at) AS INTEGER) as days_stale,
  CASE
    WHEN json_extract(metadata, '$.type') IN ('infrastructure', 'deployment', 'system', 'system-health') THEN 'refresh'
    WHEN json_extract(metadata, '$.type') IN ('business', 'philosophy', 'research', 'learning', 'learn', 'investigation', 'analysis', 'project') THEN 'refresh'
    ELSE 'archive'
  END as suggested_action
FROM nodes
WHERE updated_at < datetime('now',
  CASE
    WHEN json_extract(metadata, '$.type') IN ('infrastructure', 'deployment', 'system', 'system-health') THEN '-14 days'
    WHEN json_extract(metadata, '$.type') IN ('skill', 'documentation', 'template', 'protocol-enforcement', 'prd', 'architecture') THEN '-90 days'
    WHEN json_extract(metadata, '$.type') IN ('note', 'wal', 'WAL', 'task', 'TASK', 'event') THEN '-30 days'
    WHEN json_extract(metadata, '$.type') IN ('business', 'philosophy', 'research', 'learning', 'learn', 'investigation', 'analysis', 'project') THEN '-120 days'
    WHEN json_extract(metadata, '$.type') IN ('deprecated-relay', 'audit', 'audit-report', 'incident', 'incident-report') THEN '-3650 days'
    ELSE '-45 days'
  END
)
AND json_extract(metadata, '$.state') NOT IN ('review_pending', 'deprecated', 'archived', 'not_processed')
AND (description IS NULL OR description NOT LIKE '[REVIEW:%')
ORDER BY days_stale ASC
LIMIT 10;
```

For each identified node, call `updateNode(id, { description: "[REVIEW: action] " + originalDescription })`.

## Level 2 Escalations (Kwame Decision Required)

1. **Stale nodes** flagged with `[REVIEW: …]` — Archive, refresh, or keep?
2. **Duplicate Nodes** (same title or >70% title overlap) — Merge or keep?
3. **Orphan Nodes >90 days old** — Archive or connect?

## Reporting Format

The fixer reports to Kwame via this Zulip DM:

```
🦅 Memory Fixer — [HH:MM UTC]

Level 1 fixes applied:
- Missing type: X nodes classified
- Missing namespace: Y nodes populated

Stale nodes needing review (max 10):
1. [Node #XXX] Title — X days stale, SUGGEST: refresh
2. [Node #YYY] Title — Y days stale, SUGGEST: archive
...

Duplicates needing decision:
1. [Node #AAA] vs [Node #BBB] — Same title

Orphans >90 days:
1. [Node #EEE] Title — X days stale, orphaned

Reply with:
- "archive #XXX, #YYY" to mark for archive
- "archive all" to archive all stale nodes listed
- "keep #XXX" to confirm a node is current
- "merge #AAA into #BBB" to merge duplicates
- "refresh #XXX" to mark as current
```

## Execution on Next Run

The fixer reads Kwame's previous response and **executes the decision to completion** — it must not leave a node in review-pending forever. Tagging alone is NOT enough; each confirmed decision must also update `state` and `updated_at` so the node drops out of the stale window on the next run.

> ⚠️ `updateNode` cannot set `state` to non-standard values (restricted to `processed`/`not_processed`) and cannot add metadata keys. For state transitions and `updated_at` bumps, use **direct SSH + SQLite** on the bridge host:
> ```bash
> ssh root@192.168.68.65 "sqlite3 /root/.local/share/RA-H/db/rah.sqlite \"UPDATE nodes SET metadata = json_set(metadata, '$.state', '<state>'), updated_at = datetime('now') WHERE id = <id>;\""
> ```
> Use `updateNode` only for description/source/title/link edits.

Decision → completed action mapping:

| Kwame reply | Description change | State | `updated_at` |
|---|---|---|---|
| `archive #XXX` | replace `[REVIEW: archive] ` → `[ARCHIVED] ` prefix | `archived` | bumped to now |
| `keep #XXX` / `refresh #XXX` | **clear the `[REVIEW: …]` tag entirely** | `active` | bumped to now |
| `merge #AAA into #BBB` | set `[REVIEW: merge_into #BBB]` on #AAA, then follow manual merge workflow | handled manually | bumped to now |
| `archive all` | apply the archive row to every node listed in the prior report | `archived` | bumped to now |

**Why `updated_at` must be bumped (critical):** the Level-1 staleness query keys off `updated_at < now - window`. If the fixer clears the tag but leaves a stale `updated_at`, the node is immediately re-flagged on the very next run and the cycle repeats forever. Bumping `updated_at` to now pushes the node back to the front of the window.

**Exclusion after action:** once an action is applied, the node's description no longer starts with `[REVIEW:` (archive → `[ARCHIVED]`, refresh/keep → original text), so it is not re-processed.

After all actions are applied, verify with:
```sql
SELECT id, json_extract(metadata, '$.state') FROM nodes WHERE description LIKE '[REVIEW:%';
```
The result must be 0 rows when all decisions are executed. Report what was done.

## Checks

- **State integrity:** archived nodes have `state: archived` + `[ARCHIVED]` prefix; kept nodes are `state: active` without a `[REVIEW:]` tag.
- **No review-pending forever:** after executing Kwame's decisions, `[REVIEW:%` node count must be 0.
- **Timestamps:** every executed decision bumps `updated_at`, so the node exits the stale window on the next run.
