# Phase 4 Verification

## Verdict

PASS

## Requirement Coverage

- PROG-01: PASS. Readiness map API returns learner concept readiness.
- PROG-02: PASS. Each concept maps to a challenge ladder level.
- PROG-03: PASS. Next challenge selection targets the weakest evidenced
  learner-memory concept.
- PROG-04: PASS. Boss unlocks are produced only from stable evidenced concepts.
- PROG-05: PASS. Rewards are deterministic, evidence-backed, and do not punish
  missed days or use random reward mechanics.

## Evidence

- `go test ./...` passed.
- `openspec validate bootstrap-job-tutor-platform --strict` passed.
- Live diagnostic create/answer plus readiness and next-challenge smoke passed.
- Go source line-count check passed.

## Residual Risk

Progression is currently an in-memory projection. It is enough for MVP proof but
will need persisted campaign state before real streaks or long-running
readiness histories.
