StageConfig.modelId; InferenceRouter gains a backward-compatible model-aware
route() overload (default ignores modelId, so static routers and test fakes are
unaffected). New ManagedInferenceRouter (infra commons) resolves a target model
per stage (stage.modelId > capability match > default) and ensureLoaded()s it
before routing, returning the live managed provider — its id changes with the
resident model, so there is no stale health cache to invalidate on swap.
ModelManager.ensureLoaded default delegates to the idempotent load(). Main wires
the managed router on the [[models]] path; the static path keeps DefaultInferenceRouter.
Plan: docs/plans/2026-05-31-model-lifecycle-management.md (slice 2 of 5).
Implements the full conversational router facade: RouterState, RouterReducer,
RouterProjector, RouterRepository, RouterContextBuilder, RouterFacade, protocol
types, WebSocket wiring, infrastructure factory, and deterministic test suite.
Also fixes spec divergences found in post-implementation review:
- Add SteeringNote domain object to core:context (epic prerequisite)
- Rename RouterFacade.handleChat → onUserInput per spec interface contract
- Add in-memory ConcurrentHashMap conversation history to DefaultRouterFacade
- Make RouterRepository.getRouterState suspend
- Rename RouterConfig.keepLast → conversationKeepLast, fix defaults (6, 4096)
- Refactor InfrastructureModule.createRouterFacade to self-assemble internally
- Fix FileReadTool: allowedPaths was dead constructor param (@SuppressUnusedParameter);
now stored as private val and enforced in validateRequest
- Disable koverVerify on modules tested via testing/ submodules or with
hardware/integration dependencies (24 modules); build gate now passes clean
New core:artifacts-store interface + infrastructure/artifacts-cas
implementation: segment files + SQLite index, Blake3 hashing,
group-commit fsync via flushBefore, recovery tail-scan, manual
compactor, and oldest-first disk-cap evictor.
Inference events now carry promptArtifactId / responseArtifactId;
orchestrators put bytes before emitting. SqliteEventStore wraps
its txn in artifactStore.flushBefore so segment data is fsynced
before the event commit, making the crash window non-corrupting
(TailScanner re-indexes orphan tail records on reopen).
Compactor and evictor are mutually exclusive via maintenanceMutex.
Step 9 (cloud sync) deferred to a later epic.
See docs/reviews/2026-05-18-cas-steps-1-8-review.md for the final
review.
