The shipped Store 1 persisted repo-file descriptors in a new SqliteObservationStore
— a second, unsynchronized SQLite writer on the event-log DB (no WAL/busy_timeout,
one shared Connection across coroutines) holding a fact the log already carries. That
violates "the event log is the only source of truth" (inv #1/#8): an Observation is
just FileWrittenEvent.path + postImageHash + describe(bytes).render(), and render is a
pure function of content-addressed CAS bytes.
Replace the whole durable apparatus with an in-process memo (descriptorMemo, keyed on
repoRoot+path+contentHash) on the orchestrator, next to the existing artifactContentCache.
Rebuilt from the log on restart, disposable, no external store. Preserves the perf win
(skip CAS read + regex on repeat describes) with none of the concurrency/lock risk.
Deletes: ObservationStore/InMemoryObservationStore/SqliteObservationStore (+ tests),
InfrastructureModule.createObservationStore, the FileReadTool priming path (which never
hit anyway — it keyed on a workspace-relative path while every consumer looks up the
absolute FileWrittenEvent.path), the FileReadConfig/SessionOrchestrator plumbing, and
five orphaned build.gradle deps.
Store 2 (soft-confidence hints) unchanged — it was correct.

Store 2 (Fixes): ConceptCompilerProjection already tracked the
unconfirmed(validatedFixes>=1)/falsified(contradicted)/confirmed(promoted)
lifecycle as data, but only confirmed (>=threshold) clusters were ever
delivered. unconfirmedFixEntries reactively matches the CURRENT retry's
classKey against that state and injects a soft one-shot hint (below
threshold) or steer-away (contradicted) before hard promotion — wired
into stage context build in SessionOrchestratorExecution.kt.
Store 3 (Plan-shapes): already shipped as SessionOrchestratorPlanPatterns.kt
(deterministic keyword-Jaccard over eventStore.allEvents(), no embedder
needed) — confirmed complete, no new code required.
FileReadTool hot-path extension to Store 1: a whole-file read now primes
the cross-session ObservationStore (when wired) the same way the write
path already does, so a later describeCached lookup for the same content
hash is warm even if the file was only read, not written, this session.
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
