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.

---

8) Performance Validation for Personal Scale

Goal: Confirm acceptable responsiveness for expected personal-use workload.

Implementation Steps

1. Define practical performance expectations for key flows.
2. Run representative tests using real document samples.
3. Address obvious bottlenecks in queries, file handling, or worker concurrency.
4. Document known limits and expected operating bounds.

Deliverables

• Short performance validation note
• Known-limits summary

Exit Criteria

• Core flows remain responsive for expected corpus size and usage patterns.

---

9) Release Readiness and Environment Simplicity

Goal: Make deployment and rollback repeatable for a single-operator Docker Compose setup.

Implementation Steps

1. Define a simple release checklist:
   • 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.

10) Documentation Completion

Goal: Ensure V1 can be built, operated, and supported from documentation.

Implementation Steps

1. Update core project docs to match final V1 behavior:
   • Architecture
   • Error handling
   • Requirements status
   • Index/navigation
   • Intent alignment summary
2. Add operator troubleshooting guides.
3. Add integration/API examples for the operator and future maintainers.
4. Publish changelog/version notes for V1.

Deliverables

• Updated documentation set for V1
• V1 release notes

Exit Criteria

• A future maintainer can run and support the system using docs alone.

---

11) Final Validation and Launch

Goal: Confirm V1 readiness and launch with low operational risk.

Implementation Steps

1. Run end-to-end acceptance validation against the V1 traceability matrix.
2. Complete operator acceptance checks on representative real documents.

---

12) Post-Launch Stabilization

Goal: Address early issues quickly and lock in a reliable V1 baseline.

Implementation Steps

1. Track defects and operational pain points observed after launch.
2. Prioritize short-cycle stabilization fixes.
3. Remove temporary launch-only workarounds when safe.
4. Capture a brief retrospective and update the next-phase backlog.

Deliverables

• Stabilization summary
• Updated backlog for post-V1 enhancements

Exit Criteria

• Major launch issues are resolved.

• 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.
