# Phase 2 Execution Plan: Plan -> Routine -> Habit

> **Status:** Complete
> **Owner:** `learning_ai_common_plat`
> **Golden Flow:** FlowMonk plan -> ChronoMind routine -> EffoRise habit
> **Primary Lead:** Codex

## 1. Scope

This phase implements the second ecosystem handoff seam:

1. FlowMonk exports a canonical `plan` artifact
2. ChronoMind consumes that plan and creates a canonical `routine` artifact
3. EffoRise consumes that routine and creates a canonical `habit` artifact
4. the event lineage remains replayable through persisted latest-event indexes

This phase uses the same narrow, disk-backed proof strategy as Phase 1.

- [`learning_ai_flowmonk`](/Users/saravana/BytelystAI/learning_ai/learning_ai_flowmonk)
- [`learning_ai_clock`](/Users/saravana/BytelystAI/learning_ai/learning_ai_clock)
- [`learning_ai_efforise`](/Users/saravana/BytelystAI/learning_ai/learning_ai_efforise)

---

## 3. Contract Decisions

- `artifact.created` remains the canonical creation event for `plan`, `routine`, and `habit`
- `artifact.linked` remains the canonical linkage event for generated downstream artifacts
- `EcosystemArtifactTypeSchema` now includes `habit`
- link relations now include `generated-habit`
- no product-specific `plan.created` or `plan.habit.generated` event names were introduced in this phase

## 4. Implementation Summary

### 4.1 learning_ai_common_plat

- [x] extend shared artifact types for `plan`, `routine`, and `habit`
- [x] extend generic event payloads so `artifact.created` can carry the new artifact types
- [x] extend `artifact.linked` relation vocabulary for `generated-routine` and `generated-habit`
- [x] add contract tests covering the new artifact and event shapes

Commit:

- `78918fb` `feat(events): add phase2 plan routine habit contracts`

### 4.2 learning_ai_flowmonk

- [x] add `backend/src/lib/ecosystem-phase2.ts`
- [x] build a canonical `plan` artifact from planning-export data
- [x] persist latest plan artifact + created-event indexes
- [x] add focused producer test

Commit:

- `59ab8b1` `feat(phase2): export flowmonk plan artifacts`

### 4.3 learning_ai_clock

- [x] add `backend/src/lib/ecosystem-phase2.ts`
- [x] import the latest `plan` artifact into a `routine`
- [x] persist latest routine artifact + created/linked-event indexes
- [x] preserve upstream plan-created causation
- [x] add focused consumer/producer test

Commit:

- `fdd3743` `feat(phase2): import chronomind routines from plans`

### 4.4 learning_ai_efforise

- [x] add `backend/src/lib/ecosystem-phase2.ts`
- [x] import the latest `routine` artifact into a `habit`
- [x] persist latest habit artifact + created/linked-event indexes
- [x] preserve upstream routine-linked causation
- [x] add focused consumer/producer test

Commit:

- `4975498` `feat(phase2): import efforise habits from routines`

## 5. Verification

### Shared contract

- [x] `pnpm exec vitest run src/ecosystem.test.ts`
      Workdir:
      `learning_ai_common_plat/packages/events`
      Result:
      `1` file passed, `5` tests passed.

### Repo-local focused tests

- [x] `node --experimental-strip-types --test backend/src/lib/ecosystem-phase2.test.ts`
      Workdir:
      `learning_ai_flowmonk`
      Result:
      `1` test passed.

- [x] `node --experimental-strip-types --test backend/src/lib/ecosystem-phase2.test.ts`
      Workdir:
      `learning_ai_clock`
      Result:
      `1` test passed.

- [x] `node --experimental-strip-types --test backend/src/lib/ecosystem-phase2.test.ts`
      Workdir:
      `learning_ai_efforise`
      Result:
      `1` test passed.

### Manual end-to-end walkthrough

- [x] manual walkthrough completed at `/tmp/bytelyst-phase2-walkthrough.WpEjZu`
- [x] persisted causal chain:
      `evt_plan_created_b202f23f69a4 -> evt_routine_created_4c07d3fdcd07 -> evt_routine_linked_08b9db8a7013 -> evt_habit_created_f532f13332d1 -> evt_habit_linked_7be9a47928e3`

## 6. Closeout Decision

- `complete`

Phase 2 is complete as a contract-backed ecosystem handoff.
Future route/UI adoption can build on these modules, but the artifact/event seam itself is now implemented and verified.
