# Version 1 Implementation Plan

This plan defines the path from MVP to **Version 1 complete**.  
The objective is to deliver the full scoped product with readiness for reliable personal-scale operation, while explicitly separating refinements/enhancements into a future document.

---

## 0) Plan Governance & Scope Control (Foundation)

**Goal:** Keep execution focused on V1 completion and avoid unnecessary process overhead.

### Implementation Steps
1. Create and maintain a **V1 Traceability Matrix**:
   - Requirement ID
   - Current status (`done`, `partial`, `not started`)
   - Validation method
2. Define V1 completion gates:
   - Functional complete
   - Operationally complete
   - Personal-deployment ready
3. Snapshot the MVP baseline (tag/changelog reference).
4. Keep a standing rule: non-V1 ideas go to a separate enhancements backlog, and enter V1 only by explicit approval.

### Deliverables
- `docs/ver1/ver1.md` (this plan)
- V1 traceability artifact:
  - `docs/ver1/ver1-step1-2-carry-forward-checklist.md`
  - `docs/ver1/ver1-step2-error-path-inventory.md` (supporting artifact)

### Exit Criteria
- Every in-scope requirement has explicit status and validation evidence.
- Scope-change discipline is followed consistently.

---

## 1) Architecture Consolidation

**Goal:** Align implementation with intended architecture while preserving simplicity.

### Implementation Steps
1. Compare implemented modules/components with architecture documentation.
2. Identify and classify architectural debt:
   - Temporary coupling
   - Missing interfaces
   - Placeholder services/components
3. Resolve architecture gaps that threaten reliability, maintainability, or clear boundaries.
4. Record material decisions and tradeoffs in ADRs.

### Deliverables
- Updated architecture diagrams and boundaries
- ADR entries for material decisions

### Exit Criteria
- Architecture documentation reflects system reality.
- High-impact architecture risks are addressed or explicitly scheduled.

---

## 2) Error Handling & Reliability Hardening

**Goal:** Ensure predictable, diagnosable behavior under expected failure conditions.

### Implementation Steps
1. Apply the canonical taxonomy and response model from `docs/error_handling.md` across UI/API/service/worker boundaries.
2. Ensure clear distinction between:
   - User-facing safe messages
   - Internal diagnostic detail
   - Retryable vs non-retryable failures
3. Implement practical resilience controls where needed:
   - Timeouts
   - Bounded retries with backoff
   - Explicit terminal failure states
4. Add failure-path tests for critical workflows.

### Deliverables
- Error handling reference aligned with `docs/error_handling.md`
- Failure-mode test coverage for critical paths

### Exit Criteria
- Error behavior is consistent across major flows.
- Known failure scenarios are tested and pass.
- Failed jobs include actionable, traceable failure detail.

## 3) Functional Completion by Requirement Domain

**Goal:** Complete all V1 requirements in a practical, user-first order.

### Recommended Order
1. End-user core flows (upload → transcribe → review)
2. Data integrity and persistence behavior
3. Minimal operator controls needed for personal use
4. In-scope UX quality improvements

### Implementation Steps
For each requirement slice:
1. Confirm contract/schema
2. Implement service/domain logic
3. Implement persistence/state transitions
4. Integrate API/UI behavior
5. Add or update automated tests
6. Update relevant docs

### Deliverables
- Requirement completion report with validation evidence linked to REQ IDs

### Exit Criteria
- All V1 must-have requirements are complete and verified.

## 4) Data Model and Migration Safety

**Goal:** Keep schema evolution safe and simple for personal-scale deployment.

### Implementation Steps
1. Validate schema against finalized V1 domain needs.
2. Implement forward-safe migrations for expected upgrades.
3. Define a simple rollback/mitigation path for migration failures.
4. Add backfill scripts only where truly required.
5. Rehearse migration + rollback locally using representative sample data.

### Deliverables
- Migration and rollback runbook
- Backfill checklist (if applicable)

### Exit Criteria
- Migration path is tested and documented.
- No unresolved data-loss risk for V1 upgrade.

---

## 5) Private-Network Safety Baseline

**Goal:** Apply right-sized security controls for a single-user system on a trusted private network.

### Implementation Steps
1. Enforce private-network deployment assumptions in docs and configuration.
2. Ensure basic single-operator access control for UI/API actions.
3. Enforce input validation and safe error output behavior.
4. Keep secrets out of source control; document local secret handling.
5. Run lightweight dependency/security scanning and resolve high-risk findings.

### Deliverables
- Security assumptions checklist (private network, single operator)
- Basic risk update for V1 scope

### Exit Criteria
- No unresolved critical vulnerabilities.
- Access behavior and validation rules are verified for intended operating model.

---

## 6) Minimal Observability & Operability

**Goal:** Keep operation and troubleshooting simple, clear, and reliable.

### Implementation Steps
1. Standardize structured logging across UI/API/service/worker boundaries.
2. Ensure logged errors include category and error reference IDs per `error_handling.md`.
3. Add lightweight health/startup checks.
4. Document a concise operator runbook:
   - start/stop
   - log locations
   - common failure patterns and recovery steps
5. Add minimal counters/timings only where they clearly improve diagnosis.

### Deliverables
- Logging and error-traceability baseline
- Operator runbook

### Exit Criteria
- Operator can diagnose common failures using logs + runbook.
- System recovery procedures are documented and repeatable.

---

## 7) Test Coverage and Practical Quality Gates

**Goal:** Prevent regressions in critical flows without overbuilding test infrastructure.

### Implementation Steps
1. Expand unit and integration tests for all V1 requirement slices.
2. Add end-to-end tests for critical journeys:
   - upload
   - process/transcribe
   - view result
   - failure visibility
3. Add targeted contract tests where adapter boundaries are error-prone.
4. Keep CI gates focused on high-value checks (tests, lint, type checks, dependency scan).

### Deliverables
- V1 test matrix mapped to requirements and critical flows
- CI quality-gate checklist

### Exit Criteria
- Critical-path regressions are automatically detected.
- Test suite gives consistent release confidence for personal-scale operation.

   - run tests
   - run one end-to-end transcription check
   - verify migration compatibility
2. Document environment configuration requirements clearly.
3. Validate deployment and rollback steps in a local rehearsal.
4. Add backup/restore verification for core persisted data.

### Deliverables
- Release checklist
- Environment and rollback guide

### Exit Criteria
- Deployment/rollback is rehearsed and documented.
- Operator can release safely without hidden steps.

---

## Recommended Execution Rhythm

- **Weekly:** Requirement closure + risk review
- **As needed (small batch releases):** Run release checklist and deploy
- **Milestone check-ins:** After phases 2, 6, 9, and 11

---

## Scope Discipline Rule (V1 Focus)

To preserve delivery focus:
- V1 execution prioritizes completion of scoped requirements.
- Refinements/enhancements are captured in a separate future document and backlog.
- Only explicitly approved scope changes may enter this plan.
