NK-WP-0024 - Portal integration expansion

Track deferred integration breadth separately from the completed live MVP. Activate with the corresponding user-engine product-expansion tasks.

Provider workplans established 2026-08-08:

• FLEX-WP-0009 provides the user-engine policy package and cluster service.
• AUDIT-WP-0003 provides authenticated durable event ingestion.
• EMAIL-WP-0004 provides transactional invitation-mail delivery.

This workplan remains the consumer-side coordination and deployed integration gate; provider implementation status stays authoritative in the owning repos.

T01 - Establish flex-auth production authorization

id: NK-WP-0024-T01
status: progress
priority: high
state_hub_task_id: "7dff0ac6-c5eb-486c-83db-a1400f30f77d"

Define self, tenant-admin, and platform-admin resource/action vocabulary, deploy the policy package, replace user-engine's local runtime adapter with a fail-closed flex-auth HTTP adapter, and correlate decision IDs with audit.

2026-08-08 implementation: added the fail-closed flex-auth HTTP adapter in user-engine, including request mapping, decision-ID propagation, timeout and malformed-response denial tests. The role/resource contract and safe rollout gate are recorded in docs/user-engine-platform-expansion-contract.md. Deployment remains pending because no cluster-local flex-auth Service or validated user-engine policy package currently exists on railiance01.

2026-08-09 deployment: the validated user-engine policy is live at flex-auth-user-engine.flex-auth.svc.cluster.local:8080; an in-namespace live probe produced self-service allow and cross-tenant deny decisions. The portal runtime switch remains coupled to the event/mail activation gate below.

T02 - Add invitation and verification mail delivery

id: NK-WP-0024-T02
status: progress
priority: medium
state_hub_task_id: "9d5f272b-115c-404d-8387-7f987cee65ea"

Deliver invitation and verification messages through approved custody and mail lanes. Mailbox ownership remains evidence, never authorization.

2026-08-08 implementation: added authenticated, idempotent invitation-mail delivery from durable outbox events. The delivery token is a required runtime secret and the NetKingdom contract pins it to the existing OpenBao runtime lane. Live completion waits for an approved mail receiver and its custody entry; production is deliberately not pointed at a fabricated endpoint.

T03 - Operate durable event delivery

id: NK-WP-0024-T03
status: progress
priority: high
state_hub_task_id: "17d6390b-05a8-436c-879b-4e0331d85be5"

Connect the user-engine transactional outbox to the platform event lane with bounded retries, replay, dead-letter visibility, redaction, and correlation.

2026-08-08 implementation: added an authenticated HTTP event adapter carrying event ID, tenant, correlation, occurrence time, and redacted domain payload. It uses Idempotency-Key; the existing durable store supplies bounded retry, dead-letter, diagnostics, and replay. Live completion waits for a selected cluster event receiver and scoped delivery credential.

T04 - Run expanded integration failure matrix

id: NK-WP-0024-T04
status: progress
priority: high
state_hub_task_id: "4c54e8e4-19d9-4470-bb43-3d43cf27af71"

Prove flex-auth denial/unavailability, mail failure, identity-provider outage, partial provisioning recovery, invitation replay/expiry, and cross-tenant negative behavior through the deployed path.

2026-08-08 source matrix: user-engine's full suite passes 119 tests with three external-provider tests skipped. New coverage proves flex-auth allow mapping, decision correlation, fail-closed unavailability, invitation mail routing, event routing, and idempotency. Existing USER-WP-0021 coverage proves provider outage, recovery, invitation expiry/replay, dead-letter/replay, and cross-tenant denial. The deployed-path matrix remains pending on the three production endpoints above.
