Lifts inputMode/inputBuffer out of InputState into top-level TuiState,
renames InputMode variants to ROUTER/NAVIGATE/FILTER/STEER, adds
TuiToolRecord and TuiEventEntry for per-session tool/event history,
expands SessionsReducer to track tool lifecycle and recent events, and
adds ToggleApprovalOverlay/ToggleEventOverlay/EnterSteer actions.
Deletes 21 Module.kt scaffolding objects that were never wired into any DI
registry. Removes unused imports across 8 production and 3 test files.
Restores StageExecutor, CyclePolicyResolver, PolicyValidation, and
ReplayContractTest — these are deferred features, not dead code.
Removes 6 files audited as fully unused: StageExecutor interface (shadowed
by kernel), CyclePolicyResolver and PolicyValidation (deferred cycle policy),
ApprovalRoutes (never registered), TuiNavigation (superseded by reducer),
and ReplayContractTest abstract class (no concrete subclasses).
ArtifactRelationshipType and CyclePolicy were audited but retained —
both are actively referenced by production code.
- SessionEventBridge: replaySnapshot() sends all historical events on connect;
streamLive(sessionId) subscribes to live event flow per session
- DomainEventMapper: maps 14 domain event types to ServerMessage; reads
InferenceCompleted response text from ArtifactStore with empty-string fallback
- GlobalStreamHandler: wires bridge on connect for replay, launches per-session
live-stream job on StartSession, cancels all jobs on disconnect; removes
ProtocolError("ping") heartbeat hack
- SessionStreamHandler: fixes replay to use DomainEventMapper instead of
emitting SessionStarted for every event; injects real artifactStore;
removes ProtocolError("ping") heartbeat; adds structured logging throughout
- Main: startup log block showing port, model config, sandbox, stores, tools,
providers
- SessionsReducer: StageCompleted/StageFailed now clears currentStage; adds
5 missing tests (InferenceCompleted, StageStarted, ToolCompleted, SessionPaused)
- RouterPanel: new TUI widget rendering active session's lastResponseText
- TuiWsClient: remove println that was polluting the TUI on WS connect failure
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.
Add log4j2/SLF4J deps and log4j2.xml, install Ktor CallLogging, replace
manual System.err.println sites with leveled loggers, and wrap the
EventStore with a LoggingEventStore decorator so every append/appendAll
is logged in one place.
