# T7.4: Multi-Signal Ranking API Reference
|
||||
|
||||
## Overview
|
||||
|
||||
Advanced ranking with 7 configurable signals. Choose preset profiles or customize weights.
|
||||
|
||||
---
|
||||
|
||||
## Signals
|
||||
|
||||
### Semantic (Default Weight: 40%)
|
||||
Vector similarity from pgvector. Range: 0.0-1.0.
|
||||
- Higher = more semantically similar to query
|
||||
|
||||
### Lexical (Default Weight: 25%)
|
||||
BM25 ranking from OpenSearch. Range: 0.0-1.0.
|
||||
- Higher = more lexically similar to query
|
||||
|
||||
### Recency (Default Weight: 15%)
|
||||
Time decay from last update. Formula: `exp(-age_days / 30)`
|
||||
- Recent updates boost score
|
||||
- 30-day half-life (score = 0.37 at 30 days)
|
||||
|
||||
### Frequency (Default Weight: 10%)
|
||||
Access count log scale. Formula: `log(access_count + 1) / log(max_access + 1)`
|
||||
- Frequently accessed entities ranked higher
|
||||
- Normalized to 0.0-1.0
|
||||
|
||||
### Confidence (Default Weight: 5%)
|
||||
Base confidence with staleness decay. Formula: `base * exp(-staleness_days / 90)`
|
||||
- Entities confirmed recently score higher
|
||||
- 90-day half-life
|
||||
|
||||
### Community (Default Weight: 3%)
|
||||
Activity in connected community. Range: 0.0-1.0.
|
||||
- Factor 1: Community size (0-100 entities)
|
||||
- Factor 2: Recent edges (0-50 edges in 7 days)
|
||||
- Score = (size_factor + activity_factor) / 2
|
||||
|
||||
### Contradiction (Default Weight: 2%)
|
||||
Penalty for unresolved contradictions. Range: -0.3 to 0.0.
|
||||
- Formula: `-min(0.3, ratio * 0.3)` where ratio = unresolved / total
|
||||
- No contradictions = 0
|
||||
- All contradictions = -0.3

## Profiles
|
||||
|
||||
### default
|
||||
Balanced ranking across all signals.
|
||||
|
||||
**When to use**:
|
||||
- General queries
|
||||
- No specific ranking priority
|
||||
- Balanced experience
|
||||
|
||||
### recency_focused
|
||||
Prioritize recently updated entities (35% weight).
|
||||
|
||||
**When to use**:
|
||||
- Troubleshooting (recent solutions better)
|
||||
- Current best practices
|
||||
- Up-to-date documentation
|
||||
|
||||
**Example**:
|
||||
```bash
|
||||
curl -X POST http://localhost:8080/memory/query \
|
||||
-H "Authorization: Bearer $TOKEN" \
|
||||
-d '{"query": "kubernetes 1.28 best practices", "ranking_profile": "recency_focused"}'
|
||||
```
|
||||
|
||||
### accuracy_focused
|
||||
High confidence (20%) + minimal contradictions (5% penalty weight).
|
||||
|
||||
**When to use**:
|
||||
- Critical decisions (production deployments)
|
||||
- Compliance audits
|
||||
- High-stakes troubleshooting
|
||||
|
||||
**Example**:
|
||||
```bash
|
||||
curl -X POST http://localhost:8080/memory/query \
|
||||
-H "Authorization: Bearer $TOKEN" \
|
||||
-d '{"query": "database backup procedures", "ranking_profile": "accuracy_focused"}'
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Custom Profiles (Future)
|
||||
|
||||
Currently, 3 preset profiles available. Future support for custom weights:
|
||||
|
||||
```bash
|
||||
# (Not yet implemented)
|
||||
curl -X POST http://localhost:8080/memory/ranking/profiles \
|
||||
-H "Authorization: Bearer $TOKEN" \
|
||||
-d '{
|
||||
"name": "my_custom",
|
||||
"weights": {
|
||||
"semantic": 0.5,
|
||||
"lexical": 0.3,
|
||||
"recency": 0.2,
|
||||
...
|
||||
}
|
||||
}'
|
||||
```
|
||||
|
||||

|
||||
|
||||
## Signal Analysis
|
||||
|
||||
### Score Contribution Example
|
||||
|
||||
Query: "kubernetes debugging"
|
||||
Profile: recency_focused
|
||||
|
||||
| Signal | Raw | Weight | Contribution | Impact |
|
||||
|--------|-----|--------|--------------|--------|
|
||||
| semantic | 0.95 | 0.30 | 0.285 | High semantic match |
|
||||
| lexical | 0.88 | 0.15 | 0.132 | Good BM25 match |
|
||||
| recency | 0.98 | 0.35 | 0.343 | Very recent (days old) |
|
||||
| frequency | 0.72 | 0.10 | 0.072 | Moderately accessed |
|
||||
| confidence | 0.90 | 0.05 | 0.045 | Recently confirmed |
|
||||
| community | 0.65 | 0.03 | 0.020 | Active community |
|
||||
| contradiction | 0.0 | 0.02 | 0.0 | No issues |
|
||||
| **TOTAL** | | | **0.897** | **89.7% relevance** |
|
||||
|
||||
---
|
||||
|
||||
## Tuning Guide
|
||||
|
||||
### If results are too general
|
||||
- Increase semantic weight (0.40 → 0.50)
|
||||
- Decrease lexical weight (0.25 → 0.15)
|
||||
- Use `accuracy_focused` profile
|
||||
|
||||
### If results are too fresh
|
||||
- Decrease recency weight (0.15 → 0.05)
|
||||
- Increase confidence weight (0.05 → 0.15)
|
||||
- Use `accuracy_focused` profile
|
||||
|
||||
### If results have errors
|
||||
- Increase contradiction penalty (0.02 → 0.10)
|
||||
- Increase confidence weight (0.05 → 0.20)
|
||||
- Use `accuracy_focused` profile

|
||||
```
|
||||
|
||||

|
||||
|
||||
## Use Cases
|
||||
|
||||
### Daily Verification (CI)
|
||||
```bash
|
||||
#!/bin/bash
|
||||
# Run every day at 2 AM UTC
|
||||
|
||||
TOKEN=$(get_jwt_token)
|
||||
RESULT=$(curl -s -X POST http://localhost:8080/memory/rebuild \
|
||||
-H "Authorization: Bearer $TOKEN" \
|
||||
-d '{
|
||||
"project": "poimen",
|
||||
"verify": true,
|
||||
"dry_run": false
|
||||
}')
|
||||
|
||||
STATUS=$(echo $RESULT | jq -r '.status')
|
||||
MATCH=$(echo $RESULT | jq -r '.checksum.match')
|
||||
|
||||
if [ "$MATCH" != "true" ]; then
|
||||
echo "CRITICAL: Rebuild parity failed!"
|
||||
echo $RESULT | jq '.diff_summary'
|
||||
alert_team
|
||||
exit 1
|
||||
fi
|
||||
|
||||
echo "OK: Rebuild is deterministic"
|
||||
```
|
||||
|
||||
### Dry-Run Before Production
|
||||
```bash
|
||||
# Test the rebuild without committing
|
||||
curl -X POST http://localhost:8080/memory/rebuild \
|
||||
-H "Authorization: Bearer $TOKEN" \
|
||||
-d '{
|
||||
"project": "prod",
|
||||
"verify": true,
|
||||
"dry_run": true
|
||||
}'
|
||||
|
||||
# Response shows what would happen
|
||||
# If satisfied, run again without dry_run
|
||||
```
|
||||
|
||||
### Incremental Rebuild
|
||||
```bash
|
||||
# For large datasets, resume from checkpoint
|
||||
curl -X POST http://localhost:8080/memory/rebuild \
|
||||
-H "Authorization: Bearer $TOKEN" \
|
||||
-d '{
|
||||
"project": "poimen",
|
||||
"verify": true,
|
||||
"from_checkpoint": "cp-2025-01-29"
|
||||
}'
|
||||
```
|
||||
|
||||
### Post-Incident Recovery
|
||||
```bash
|
||||
# After fixing corruption, verify system recovers
|
||||
curl -X POST http://localhost:8080/memory/rebuild \
|
||||
-H "Authorization: Bearer $TOKEN" \
|
||||
-d '{
|
||||
"project": "poimen",
|
||||
"verify": true
|
||||
}'
|
||||
|
||||
# Check status
|
||||
curl -H "Authorization: Bearer $TOKEN" \
|
||||
http://localhost:8080/memory/rebuild/status
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Checksum Details
|
||||
|
||||
### Computation
|
||||
```
|
||||
checksum = SHA256(
|
||||
sorted_entity_ids ||
|
||||
sorted_edge_ids ||
|
||||
event_metadata
|
||||
)
|
||||
```
|
||||
|
||||
**Deterministic because**:
|
||||
1. Entities sorted by ID (no random order)
|
||||
2. Edges sorted by ID
|
||||
3. Event replay sequential (no async variation)
|
||||
4. Embedding model pinned (same version)
|
||||
5. JSON serialization canonical (sorted keys)
|
||||
|
||||
### Interpretation
|
||||
|
||||
**Checksums match** (`match: true`):
|
||||
- ✅ Rebuild is byte-identical
|
||||
- ✅ No hidden non-determinism
|
||||
- ✅ Data is consistent
|
||||
|
||||
**Checksums differ** (`match: false`):
|
||||
- ❌ Non-determinism detected
|
||||
- ❌ Investigate: embedding model change? Event log corruption?
|
||||
- ❌ BLOCK further rebuilds until root cause fixed

## Incident: Rebuild Parity Failure
|
||||
|
||||
**Severity**: CRITICAL | **Impact**: Data integrity at risk | **SLO**: Consistency 100%
|
||||
|
||||
### Detection
|
||||
|
||||
Alert: `RebuildParityFailed`
|
||||
Symptoms:
|
||||
- Daily CI rebuild check fails
|
||||
- Checksums don't match before/after
|
||||
- Diff summary shows unexpected changes
|
||||
|
||||
### Immediate Actions (0-5 minutes)
|
||||
|
||||
1. **Acknowledge and declare incident**
|
||||
```bash
|
||||
# In war room: incident declare rebuild-parity-$(date +%s)
|
||||
```
|
||||
|
||||
2. **Assess scope**
|
||||
```bash
|
||||
# Get last successful rebuild
|
||||
curl -H "Authorization: Bearer $TOKEN" \
|
||||
http://localhost:8080/memory/rebuild/status \
|
||||
| jq '.last_rebuild | {rebuild_id, checksum, records_processed}'
|
||||
```
|
||||
|
||||
3. **Block writes** (if corruption suspected)
|
||||
```bash
|
||||
# Stop ingest pipeline
|
||||
kubectl scale deployment memory-ingest --replicas=0 -n poimen
|
||||
```
|
||||
|
||||
### Investigation (5-30 minutes)
|
||||
|
||||
1. **Check logs for non-determinism**
|
||||
```bash
|
||||
# Look for embedding model version changes
|
||||
kubectl logs -l app=memory -c worker -n poimen --since=24h | grep -i "embedding\|model\|version"
|
||||
|
||||
# Check for floating point precision issues
|
||||
kubectl logs -l app=memory -c worker -n poimen --since=24h | grep -i "float\|precision\|nan"
|
||||
```
|
||||
|
||||
2. **Verify event log integrity**
|
||||
```bash
|
||||
# Count records in event log vs database
|
||||
EVENTS=$(psql $DB -c "SELECT COUNT(*) FROM event_log WHERE project_id='poimen'" --csv | tail -1)
|
||||
ENTITIES=$(psql $DB -c "SELECT COUNT(*) FROM memory_entity WHERE project_id='poimen'" --csv | tail -1)
|
||||
|
||||
echo "Event log: $EVENTS, DB entities: $ENTITIES"
|
||||
[ "$EVENTS" -eq "$ENTITIES" ] || echo "MISMATCH: corruption likely"
|
||||
```
|
||||
|
||||
3. **Check for dependency changes**
|
||||
```bash
|
||||
# Get current container image versions
|
||||
kubectl get pods -l app=memory -o jsonpath='{.items[*].spec.containers[*].image}' -n poimen
|
||||
|
||||
# Compare to expected (git tag)
|
||||
git show HEAD:deploy/memory-deployment.yaml | grep image:
|
||||
```
|
||||
|
||||
### Resolution
|
||||
|
||||
**If embedding model changed** (likely cause):
|
||||
```bash
|
||||
# Option 1: Revert to previous model version
|
||||
kubectl set env deployment memory EMBEDDINGS_MODEL=sentence-transformers/all-MiniLM-L6-v2:v0.1 -n poimen
|
||||
kubectl rollout restart deployment memory -n poimen
|
||||
|
||||
# Wait for rebuild to complete
|
||||
sleep 300
|
||||
|
||||
# Re-run verification
|
||||
curl -X POST http://localhost:8080/memory/rebuild \
|
||||
-H "Authorization: Bearer $TOKEN" \
|
||||
-d '{"project":"poimen","verify":true}'
|
||||
```
|
||||
|
||||
**If event log corrupted** (rare):
|
||||
```bash
|
||||
# Restore from backup
|
||||
kubectl exec -it memory-backup-pod /bin/bash << 'EOF'
|
||||
pg_restore -d memory /backups/memory-$(date -d '1 day ago' +%Y-%m-%d).sql
|
||||
EOF
|
||||
|
||||
# Verify
|
||||
curl -X POST http://localhost:8080/memory/rebuild \
|
||||
-H "Authorization: Bearer $TOKEN" \
|
||||
-d '{"project":"poimen","verify":true}'
|
||||
```
|
||||
|
||||
**If timestamp drift** (clock skew):
|
||||
```bash
|
||||
# Verify NTP sync on all nodes
|
||||
timedatectl status
|
||||
chronyc tracking
|
||||
|
||||
# If unsync, force resync
|
||||
chronyc -a makestep
|
||||
|
||||
# Re-run rebuild
|
||||
curl -X POST http://localhost:8080/memory/rebuild \
|
||||
-H "Authorization: Bearer $TOKEN" \
|
||||
-d '{"project":"poimen","verify":true}'
|
||||
```
|
||||
|
||||
### Prevention
|
||||
|
||||
- Pin embedding model version in deployment
|
||||
- Automated tests for embedding determinism
|
||||
- Daily rebuild CI (catch early)
|
||||
- Event log backups (hourly)
|
||||
|
||||
### Escalation
|
||||
|
||||
If root cause unknown after 30 min:
|
||||
```bash
|
||||
# Escalate to engineering
|
||||
pagerduty trigger --title "Rebuild parity: unknown cause" \
|
||||
--description "$(curl -s http://localhost:8080/memory/rebuild/status | jq -c .)"
|
||||
```

|
||||
## Incident: Audit Chain Broken
|
||||
|
||||
**Severity**: CRITICAL | **Impact**: Compliance violation | **SLO**: Consistency 100%
|
||||
|
||||
### Detection
|
||||
|
||||
Alert: `AuditChainBroken`
|
||||
Symptoms:
|
||||
- Audit integrity check fails
|
||||
- Specific entity version has broken hash chain
|
||||
- Compliance audit fails
|
||||
|
||||
### Immediate Actions (0-5 minutes)
|
||||
|
||||
1. **Identify affected entity**
|
||||
```bash
|
||||
# Get entity with broken chain
|
||||
ENTITY=$(curl -s http://localhost:8080/memory/audit/verify \
|
||||
-H "Authorization: Bearer $TOKEN" \
|
||||
| jq -r '.first_broken_at.entity_id')
|
||||
|
||||
echo "Affected: $ENTITY"
|
||||
```
|
||||
|
||||
2. **Document for compliance**
|
||||
```bash
|
||||
# Create incident record
|
||||
cat > /tmp/audit-incident.json << EOF
|
||||
{
|
||||
"timestamp": "$(date -Iseconds)",
|
||||
"entity_id": "$ENTITY",
|
||||
"broken_at_version": $(curl -s http://localhost:8080/memory/entities/$ENTITY/versions \
|
||||
-H "Authorization: Bearer $TOKEN" | jq '.total'),
|
||||
"severity": "critical",
|
||||
"action": "see runbook"
|
||||
}
|
||||
EOF
|
||||
|
||||
# Save for audit trail
|
||||
cp /tmp/audit-incident.json /var/log/poimen/audit-incident-$(date +%s).json
|
||||
```
|
||||
|
||||
### Investigation (5-30 minutes)
|
||||
|
||||
1. **Check for unauthorized writes**
|
||||
```bash
|
||||
# Get who made the change
|
||||
curl -s http://localhost:8080/memory/entities/$ENTITY/versions \
|
||||
-H "Authorization: Bearer $TOKEN" \
|
||||
| jq '.versions[] | {version_num, changed_by, changed_at}'
|
||||
```
|
||||
|
||||
2. **Check for DB trigger bypass**
|
||||
```bash
|
||||
# Verify immutability trigger exists
|
||||
psql $DB -c "SELECT trigger_name, event_object_table FROM information_schema.triggers WHERE trigger_name LIKE '%immutable%';"
|
||||
|
||||
# If missing, recreate
|
||||
psql $DB -f crates/mem-store/migrations/007_versioning_schema.sql
|
||||
```
|
||||
|
||||
3. **Check Authentik logs for unauthorized access**
|
||||
```bash
|
||||
# Get Authentik audit
|
||||
kubectl logs -l app=authentik -n iam --since=24h | grep -i "$ENTITY\|unauthorized\|denied"
|
||||
```
|
||||
|
||||
### Resolution
|
||||
|
||||
**Audit logs are immutable** — cannot repair. Options:
|
||||
|
||||
1. **Document incident for compliance**
|
||||
```bash
|
||||
# Create compliance report
|
||||
cat > /tmp/compliance-report.md << EOF
|
||||
# Audit Chain Integrity Incident
|
||||
|
||||
**Date**: $(date)
|
||||
**Severity**: Critical
|
||||
**Entity Affected**: $ENTITY
|
||||
**Root Cause**: [Investigation finding]
|
||||
|
||||
## Actions Taken
|
||||
1. Incident documented
|
||||
2. Authentik access logs reviewed
|
||||
3. Immutability trigger verified
|
||||
4. [Preventive action]
|
||||
|
||||
## Compliance Impact
|
||||
- Audit trail for $ENTITY versions is compromised
|
||||
- Recommend manual review of $ENTITY history
|
||||
- All future versions protected by restored trigger
|
||||
EOF
|
||||
|
||||
# Store in compliance folder
|
||||
cp /tmp/compliance-report.md /var/log/poimen/compliance-incidents/
|
||||
```
|
||||
|
||||
2. **Restore trigger and lock down**
|
||||
```bash
|
||||
# Re-create immutability trigger
|
||||
psql $DB -f crates/mem-store/migrations/007_versioning_schema.sql
|
||||
|
||||
# Verify it worked
|
||||
psql $DB -c "UPDATE memory_entity_version SET operation='test' LIMIT 1" || echo "Trigger working"
|
||||
```
|
||||
|
||||
3. **Investigate root cause**
|
||||
- Was trigger accidentally dropped?
|
||||
- Was there an emergency maintenance window?
|
||||
- Was there an accidental SQL injection?
|
||||
- Was there a permission escalation?
|
||||
|
||||
### Prevention
|
||||
|
||||
- Immutability trigger on all audit tables
|
||||
- Regular trigger verification (weekly)
|
||||
- Authentik audit log retention (1 year)
|
||||
- Database role separation (no direct table updates)
|
||||
|
||||
### Escalation
|
||||
|
||||
After confirmation of compromise:
|
||||
```bash
|
||||
# Notify compliance/legal team
|
||||
notify compliance-team << EOF
|
||||
Audit chain integrity compromised for entity: $ENTITY
|
||||
See: /var/log/poimen/compliance-incidents/audit-chain-$(date +%Y-%m-%d).md
|
||||
EOF
|
||||
```
|
||||
|
||||

|
||||
|
||||
## Incident: Version Query Timeout
|
||||
|
||||
**Severity**: MEDIUM | **Impact**: Slow audits | **SLO**: Latency p99 < 500ms
|
||||
|
||||
### Detection
|
||||
|
||||
Alert: `MemoryVersionLatencyHigh`
|
||||
Symptoms:
|
||||
- `GET /memory/entities/{id}/versions` takes > 500ms
|
||||
- Audit reports slow
|
||||
- Dashboard unresponsive
|
||||
|
||||
### Investigation
|
||||
|
||||
1. **Check query performance**
|
||||
```bash
|
||||
# Explain the query
|
||||
psql $DB << EOF
|
||||
EXPLAIN ANALYZE
|
||||
SELECT * FROM memory_entity_version
|
||||
WHERE entity_id = 'e_kubernetes'
|
||||
ORDER BY version_num DESC;
|
||||
EOF
|
||||
```
|
||||
|
||||
2. **Check index status**
|
||||
```bash
|
||||
# Verify indexes exist and are healthy
|
||||
psql $DB -c "SELECT schemaname, tablename, indexname FROM pg_indexes WHERE tablename LIKE 'memory_entity_version';"
|
||||
|
||||
# Check if bloated
|
||||
psql $DB -c "SELECT * FROM pgstattuple('memory_entity_version');"
|
||||
```
|
||||
|
||||
### Resolution
|
||||
|
||||
1. **If indexes missing or bloated**
|
||||
```bash
|
||||
# Rebuild indexes
|
||||
psql $DB << EOF
|
||||
REINDEX TABLE memory_entity_version;
|
||||
REINDEX TABLE memory_edge_version;
|
||||
ANALYZE memory_entity_version;
|
||||
ANALYZE memory_edge_version;
|
||||
EOF
|
||||
```
|
||||
|
||||
2. **If table too large, partition by entity_id**
|
||||
```bash
|
||||
# Add range partition (future improvement)
|
||||
# For now, truncate old versions
|
||||
psql $DB << EOF
|
||||
DELETE FROM memory_entity_version
|
||||
WHERE changed_at < NOW() - INTERVAL '1 year';
|
||||
EOF
|
||||
```
|
||||
|
||||

|
||||
|
||||
## Incident: Ranking Profile Not Working
|
||||
|
||||
**Severity**: LOW | **Impact**: Search quality | **SLO**: None (feature)**
|
||||
|
||||
### Detection
|
||||
|
||||
Symptoms:
|
||||
- `GET /memory/ranking/profiles` returns empty
|
||||
- Query with `ranking_profile: "recency_focused"` returns 400
|
||||
- Ranking signals are all 0
|
||||
|
||||
### Investigation
|
||||
|
||||
1. **Check profile endpoint**
|
||||
```bash
|
||||
curl -v http://localhost:8080/memory/ranking/profiles \
|
||||
-H "Authorization: Bearer $TOKEN"
|
||||
```
|
||||
|
||||
2. **Check signal computation in logs**
|
||||
```bash
|
||||
kubectl logs -l app=memory -c worker -n poimen --tail=100 | grep -i signal
|
||||
```
|
||||
|
||||
### Resolution
|
||||
|
||||
1. **Restart ranking service**
|
||||
```bash
|
||||
kubectl rollout restart deployment memory -n poimen
|
||||
```
|
||||
|
||||
2. **Verify profiles loaded**
|
||||
```bash
|
||||
curl http://localhost:8080/memory/ranking/profiles \
|
||||
-H "Authorization: Bearer $TOKEN" | jq '.profiles | length'
|
||||
# Should return 3
|
||||
```
