ADR-075: Wire Self-Learning Pipeline End-to-End

Status: Implemented Date: 2026-04-06 Branch: feat/wire-learning-pipeline

Context

The learning pipeline had all building blocks (SONA, LocalReasoningBank, ONNX embeddings, trajectory recording, pattern search, file persistence) but they weren't connected end-to-end. Trajectories recorded without embeddings, so distillation produced 0 patterns. The memory bridge tried to use AgentDB's ReasoningBank/LearningSystem but they require a better-sqlite3 db handle that ControllerRegistry doesn't expose.

Decision

Auto-generate embeddings in recordTrajectory — each step gets ONNX embedding (all-MiniLM-L6-v2, 384d) before distillation
Store successful trajectory steps as patterns — directly into LocalReasoningBank with confidence scoring
Wire intelligence module into hooks — session-start initializes SONA+ReasoningBank, post-task records trajectories
Wire intelligence into memory bridge — bridge registers LocalReasoningBank and SONA as controllers (bypassing AgentDB's constructor requirements)
Add patternsLearned and signalsProcessed to global stats

Verification

Capability	Before	After	Evidence
Trajectory recording	Worked but no patterns	9 patterns from 3 trajectories	`stats.patternsLearned: 9`
Embedding generation	Not called during trajectory	Auto-generated per step	ONNX all-MiniLM-L6-v2, 384d
Pattern search	0 results	Correct semantic matches	"auth" → JWT pattern (0.584), "security" → SQL injection (0.661)
Pattern persistence	File never created	`patterns.json` written	`persist.patternsExist: true`
SONA coordinator	Initialized but idle	Active with trajectories	`stats.sonaEnabled: true`
Intelligence in hooks	Not wired	session-start inits, post-task records	Automatic on every session
