# Phase 3 Summary

**Status:** Complete
**Completed:** 2026-04-26

## Delivered

- Added `internal/learnermemory` for profile, concept mastery,
  misconceptions, interventions, review schedule, and snapshots.
- Added in-memory learner memory store and service.
- Extended `GradedAnswer` with `user_id`.
- Implemented `ExtractLearningMemory` in the workflow stub.
- Wired diagnostic answer submission to memory extraction and evidence-backed
  memory application.
- Added `GET /api/v1/learners/{userID}/memory`.
- Added unit and HTTP tests for memory application and readback.

## Verification

```powershell
gofmt -w cmd internal
go test ./...
openspec validate bootstrap-job-tutor-platform --strict
```

Additional smoke check:

- Diagnostic create/answer followed by learner memory read returned 1 mastery
  entry for `user-1`.

## Deferred

- Durable database persistence.
- Memory decay and ranking.
- Repeated-mistake clustering beyond the current evidenced candidate writes.
- Progression readiness map UI/API.
