# Phase 4 Context: Progression

**Status:** Ready for execution
**Started:** 2026-04-26

## Goal

Expose visible, evidence-backed progression after diagnostic practice.

## Inputs

- OpenSpec `learning-progression` requirements.
- `docs/planning/GAMIFICATION.md`.
- Phase 3 learner memory snapshots.
- Existing workflow contracts for `NextChallenge` and `ReadinessUpdate`.

## Decisions

- Derive MVP readiness directly from learner memory.
- Keep progression read-only except for future workflow outputs.
- Do not add streak persistence yet.
- Rewards and unlocks must be deterministic and evidence-backed.

## Boundaries

In scope:

- Role readiness map API.
- Concept ladder level calculation.
- Next challenge selection API.
- Boss-style unlock when prerequisite concepts are stable.
- Tests and verification.

Out of scope:

- Frontend map UI.
- Persistent campaign/streak storage.
- Social leaderboards.
- Random reward economy.
