NK-WP-0019 - User Engine Implementation Assessment And Polish

Goal

Assess the implemented user-engine against its PRD, architecture blueprint, NetKingdom boundary contracts, and integrated test scenarios. Finalize documentation, operational readiness, release packaging, and handoff criteria for future user-account and user-manager UI work.

Scope

In scope:

• implementation review against PRD and blueprint;
• boundary review against NetKingdom IAM Profile, flex-auth, key-cape, Keycloak, OpenBao, and Railiance responsibilities;
• API/schema polish;
• operability and documentation polish;
• release readiness;
• State Hub and responsibility-map reconciliation;
• UI handoff readiness.

Out of scope:

• building user-account or user-manager UIs;
• adding new major product capabilities;
• enterprise provisioning beyond documented adapter boundaries.

state_hub_task_id: "116b5362-ebbf-4d21-83e8-bbc82e80a71a"

Implementation assessment. Review implemented behavior against INTENT.md, the PRD, the architecture blueprint, the architecture review, and NK-WP-0014 boundary contracts. Record gaps, accepted deviations, and follow-up work.

state_hub_task_id: "08bd8ca3-dd7e-41c9-b8d2-c9b7c72ceb0a"

Boundary and responsibility review. Verify that user-engine has not absorbed identity provider, MFA, credential, PDP, UI, or deployment responsibilities. Update NetKingdom responsibility-map classification if user-engine is now a shared platform service holding NetKingdom-orchestrated resources.

status: todo
priority: medium
state_hub_task_id: "b8ff89a1-cdfb-445a-ae4d-ca4fd4a455eb"

API and schema polish. Stabilize endpoint names, error taxonomy, catalog descriptor schemas, projection responses, audit event shapes, and migration contracts. Remove accidental implementation details from public contracts.

status: todo
priority: medium
state_hub_task_id: "f57d87d7-fdc8-485c-ba93-86c5a8342f04"

Operability polish. Add readiness diagnostics, metrics, structured logs, audit correlation checks, outbox drain diagnostics, cache status, and runbooks for common failure modes.

status: todo
priority: medium
state_hub_task_id: "42a01f4e-c646-4551-bd94-e122c9c16226"

Documentation and examples. Finalize developer docs for standalone setup, application onboarding, catalog authoring, projection consumption, tenant administration boundaries, and event/audit integration.

priority: medium
state_hub_task_id: "7838d62b-94eb-437a-8418-7a900cde9716"

Release readiness. Decide versioning, packaging, image/build artifacts, SBOM/security scan requirements, migration policy, and compatibility guarantees for future consumers.

status: todo
priority: low
state_hub_task_id: "19569b30-c8df-441a-b815-c9217a82abaf"

UI handoff readiness. Produce the API, projection, catalog metadata, and test fixtures needed for future user-account and user-manager repos to start without inventing separate backends.

Acceptance Criteria

• A final assessment document records what was implemented, what changed, and what remains open.
• Public API/schema/catalog/projection contracts are coherent and documented.
• Operability and release-readiness checks pass.
• NetKingdom State Hub and responsibility-map records are reconciled.
• Future UI work has a clear backend contract.

Dependencies And Sequencing

• Depends on NK-WP-0018 integrated scenario tests.
• Closes the initial user-engine implementation program and feeds future UI workplans.
