- Is there a requirement for encryption/signing of snapshots during transit/storage?
Addressing these clarifications will shape the detailed implementation plan.
## Execution Task Breakdown
To operationalize the plan, execute the following sub-tasks sequentially. Each task lists its prerequisites and expected outputs to simplify coordination across contributors.
1. **Clarify Merge Semantics (Design Task)**
- **Prerequisites**: Gather input from stakeholders on merge requirements, including conflict rules for users, identities, and sessions.
- **Actions**: Document chosen merge strategy (field preservation rules, conflict resolution order, snapshot validation needs) and update this plan accordingly.
- **Deliverables**: Design decision record or updated specification ready for implementation sign-off.
2. **Define Configuration Schema**
- **Prerequisites**: Approved merge semantics and understanding of deployment environments.
- **Actions**: Draft `SyncConfig` Go structs, configuration file layout, and validation rules; prepare example manifests in `docs/`.
- **Deliverables**: Schema proposal merged into repository, including sample configuration and documentation references.
3. **Prototype Merge-capable Importer**
- **Prerequisites**: Finalized merge semantics and schema guidance for importer flags/options.
- **Actions**: Implement `--merge` flag, dry-run support, identity/session diffing, and logging counters. Add unit tests covering merge scenarios.
- **Deliverables**: Pull request containing importer changes, tests, and updated CLI documentation.
4. **Implement Service Mode MVP**
- **Prerequisites**: Prototype importer merged; configuration structs available.
- **Actions**: Add `service` command with scheduling loop, context cancellation, and structured logging. Integrate configuration loading and sequential job execution.
- **Deliverables**: Running service mode executable with basic observability hooks and documentation updates.
5. **Add Observability and Reliability Enhancements**
- **Prerequisites**: Service mode MVP operational.
- **Actions**: Introduce metrics emission, health endpoints, retry/backoff behavior, and optional alerting hooks.
- **Deliverables**: Instrumented service with documented metrics/alerts plus corresponding tests where applicable.
6. **Expand Testing & Automation**
- **Prerequisites**: Importer and service features in place.
- **Actions**: Build integration tests using ephemeral PostgreSQL, end-to-end service sync scenarios, and update CI pipelines to run them.
- **Deliverables**: Automated test suite covering merge/service workflows with CI integration notes.
7. **Documentation & Rollout Preparation**
- **Prerequisites**: Feature implementation stabilized.
- **Actions**: Update `docs/account-service-deployment.md`, produce operator runbooks, and outline staged rollout/monitoring steps.
- **Deliverables**: Comprehensive documentation bundle and rollout checklist ready for production enablement.
8. **Operational Review & Handoff**
- **Prerequisites**: All technical tasks completed and documented.
- **Actions**: Conduct readiness review, gather final approvals, and schedule deployment. Ensure metrics and alerting are monitored during rollout.
- **Deliverables**: Signed-off deployment plan and ownership handoff notes.
