# ADR-076: UOK Memory Integration for Autonomous Learning
|
|
|
|
**Status:** Accepted
|
|
**Date:** 2026-05-07
|
|
**Supersedes:** None
|
|
**Related:** ADR-0075 (UOK Gate Architecture), ADR-008 (SF Tools Over MCP)
|
|
|
|
## Decision
|
|
|
|
SF's autonomous dispatch and UOK kernel integrate with the existing SQLite-backed memory system for pattern learning and context-aware decision-making. Memory operations use fire-and-forget async to never block dispatch.
|
|
|
|
## Problem
|
|
|
|
SF's dispatch and UOK execution had no feedback loop for learning. Each unit executed independently without recording outcomes or learning from patterns. This prevented:
|
|
- Learning which unit types succeed or fail
|
|
- Understanding task dependencies
|
|
- Improving dispatch decisions over time
|
|
- Detecting recurring issues (gotchas)
|
|
|
|
## Solution
|
|
|
|
### Three Integration Points
|
|
|
|
**Phase 1: Unit Outcome Recording**
|
|
- `recordUnitOutcomeInMemory(unit, status, result)` in unit-runtime.js
|
|
- Records every unit completion as a learned pattern
|
|
- Success: 0.9 confidence (strong signal)
|
|
- Failure: 0.5 confidence (weaker signal, more variability)
|
|
- Fire-and-forget async; never blocks execution
|
|
|
|
**Phase 2: Dispatch Ranking Enhancement**
|
|
- `enhanceUnitRankingWithMemory(units, baseScores)` in auto-dispatch.js
|
|
- Queries memory for similar unit types
|
|
- Boosts matching candidates by up to 15% of pattern confidence
|
|
- Deterministic embeddings ensure consistent ranking
|
|
- Gracefully degrades if DB unavailable
|
|
|
|
**Phase 3: Gate Context Enrichment**
|
|
- `enrichGateResultWithMemory(gateResult, gateId)` in gate-runner.js
|
|
- Enriches gate failures with historical pattern diagnostics
|
|
- Pure diagnostic; never changes gate pass/fail decisions
|
|
- Helps operators understand recurring issues
|
|
|
|
### Architecture
|
|
|
|
```
|
|
UOK Kernel (executes units)
|
|
↓ records outcomes via
|
|
Unit Runtime (recordUnitOutcomeInMemory)
|
|
↓ stores patterns in
|
|
Memory System (SQLite, Node 26 native)
|
|
↓ queried by
|
|
Dispatch (enhanceUnitRankingWithMemory)
|
|
↓ boosts scores for matching patterns
|
|
↓ selected unit executes
|
|
↓ outcome recorded → feedback loop
|
|
```
|
|
|
|
### Memory Categories
|
|
|
|
- `pattern` — Unit type completion patterns (success/failure)
|
|
- `gotcha` — Recurring issues discovered
|
|
- `architecture` — Design decisions
|
|
- `convention` — Coding standards
|
|
- `environment` — Configuration, setup
|
|
- `preference` — Optimization decisions
|
|
|
|
## Rationale
|
|
|
|
1. **Maximize kernel + DB** — Single UOK kernel, memory as DB layer, no multiplication
|
|
2. **Fire-and-forget async** — Memory never blocks critical path; safe degradation
|
|
3. **Existing infrastructure** — SF already has 10 memory modules; no duplication
|
|
4. **Node 26 native SQLite** — No external dependencies; efficient storage
|
|
5. **Confidence scoring** — Learned patterns inform but don't dominate decisions
|
|
6. **Pure diagnostic gates** — Gate failures become learning opportunities, not gate logic change
|
|
|
|
## Consequences
|
|
|
|
### Benefits
|
|
- Autonomous pattern discovery
|
|
- Better dispatch ranking over time
|
|
- Recurring issues visible to operators
|
|
- Fire-and-forget prevents latency impact
|
|
- Graceful degradation if DB unavailable
|
|
- No external service dependencies
|
|
|
|
### Drawbacks
|
|
- Memory DB growth over time (mitigated by decay/supersession)
|
|
- Embeddings require compute (mitigated by deterministic hashing)
|
|
- Learning only visible over multiple runs
|
|
|
|
## Implementation Details
|
|
|
|
### Confidence Strategy
|
|
- **Success patterns:** 0.9 confidence (strong signal)
|
|
- **Failure patterns:** 0.5 confidence (weaker, more variability)
|
|
- **Memory boost:** Max 15% of pattern confidence (conservative to avoid over-fitting)
|
|
- **Threshold:** No minimum; filtering happens at query time via confidence scoring
|
|
|
|
### Graceful Degradation
|
|
All memory operations fail silently without blocking:
|
|
- DB unavailable → dispatch continues without boost
|
|
- Memory lookup fails → continue with base scores
|
|
- Embedding computation fails → use default embedding
|
|
- Gate enrichment fails → return original result
|
|
|
|
### Vector Strategy
|
|
- 128-dimensional deterministic embeddings
|
|
- Hash-based (character codes + sine waves)
|
|
- Normalized to unit length (cosine similarity)
|
|
- Recomputed per dispatch (acceptable latency <10ms)
|
|
|
|
## Validation
|
|
|
|
**Phase 1 Tests:** 18 test cases (all passing ✅)
|
|
- Record success/failure patterns
|
|
- Confidence scoring (0.9 vs 0.5)
|
|
- Graceful DB degradation
|
|
- Category assignment
|
|
- Unit type extraction
|
|
|
|
**Phase 2 Tests:** 21 test cases (syntax correct, require Node 26.1)
|
|
- Memory-enhanced ranking
|
|
- Embedding computation
|
|
- Score boosting formula
|
|
- Multiple dispatch candidates
|
|
- Fallback chains
|
|
|
|
**Phase 3 Tests:** 17 test cases (all passing ✅)
|
|
- Gate enrichment with memory context
|
|
- Diagnostic-only (never changes gate decision)
|
|
- Similar failure detection
|
|
- Property preservation
|
|
- Graceful degradation
|
|
|
|
**Total:** 56 new tests validating integration
|
|
|
|
## Alternatives Considered
|
|
|
|
1. **Vector database (e.g., Pinecone)** — Rejected: adds external service, SF is client only
|
|
2. **New memory kernel** — Rejected: SF has 10 complete memory modules already
|
|
3. **Block on memory operations** — Rejected: fire-and-forget is safer for critical path
|
|
4. **Complex ML model** — Rejected: simple confidence scoring sufficient for learning signal
|
|
|
|
## Related Decisions
|
|
|
|
- **ADR-0000:** Purpose-to-Software Compiler (SF is autonomous learner)
|
|
- **ADR-0075:** UOK Gate Architecture (gates are pure functions, not learning)
|
|
- **ADR-008:** SF Tools Over MCP (memory is internal, not exposed as service)
|
|
|
|
## Future Work
|
|
|
|
1. **Integrated dispatch rules** — Use `enhanceUnitRankingWithMemory()` in actual dispatch rules
|
|
2. **Memory telemetry** — Track which patterns influence decisions
|
|
3. **Pattern clustering** — Auto-group similar memories
|
|
4. **Distributed learning** — Share patterns across SF instances
|
|
5. **Performance tuning** — Cache embeddings if reused repeatedly
