Threads reasoning_content across inference calls and journal renders, filters
markdown noise out of L3 repo-knowledge retrieval, adds PlanLinter H3 checks,
and tightens filesystem tool output/dir-listing behavior surfaced by prior
live QA (see project_readloop_campaign memory).
Context rework from the 2026-07-05 context-poisoning diagnosis (session
6ca236c4 read-loop):
- ContextBucket on ContextEntry: REQUIRED (task, constraints, needed
artifacts, failure feedback) is never pruned/compressed/dropped; the
build fails fast (RequiredContextOverflowException -> non-retryable
stage failure) if required alone exceeds the stage budget.
- OptionalCeilings: per-sourceType token caps for the optional block
(repoMap 1200, relevantFiles 1600, journal 800, profiles 400/600,
vocabulary 400), tuned for the 9-26B tier at 16k; enforced by
truncation (journal keeps its tail, others their head).
- Repo map is now a structural 'what exists' listing (alphabetical,
per-directory, no recency ranking, no symbols); .md/docs paths are
gated behind an explicit docs mention in the stage prompt — retrieval
hits remain the only other path for docs to enter context.
- file_written needs render as a manifest of ALL files the producing
stage wrote (projected from ArtifactContentStored -> ToolInvocation
-> FileWritten events), fixing the last-write-wins collapse; content
stays lazy behind file_read.
- Decision journal folds a stage's RETRY records into one summary line
once a later transition leaves that stage (render-time only).
- Dedupe retrieved-file lines in buildRelevantFilesEntry.
Found while live-QAing freestyle_planning on a 12B local model:
- list_dir tool: recursive, .gitignore-aware listing so weak models stop
flooding context with `ls -R` over node_modules/build/dist. Wired into
the fileRead toggle + advertised to the planner (architect_freestyle).
- ContextClassifier: assistantToolCall turns are STRUCTURED, so the token
pruner never shreds the model's own tool-call history — that was causing
amnesia loops (re-issuing calls it had already made).
- Retire instruction-doc LLMLingua pruning (DOC_SOURCE_TYPES emptied): it
fused load-bearing procedural text into unparseable soup. The static
block stays small by dropping CLAUDE.md at the loader instead.
- AgentInstructionsLoader: load only AGENTS.md, not CLAUDE.md — the latter
targets the outer assistant and polluted the agent's stage context.
- DefaultSessionReducer: WorkflowFailed flips session status to FAILED (was
stuck ACTIVE forever, so clients/approval loops never saw a terminal).
- ShellTool: run shell command lines (cd/&&/pipes) via `sh -c`; unrunnable
program is recoverable instead of an uncaught IOException killing the
stage; malformed argv (non-string/collapsed-array) rejected with guidance.
- llmlingua sidecar: cap force_tokens to max_force_token (big docs blew the
assert and 500'd, so doc pruning silently failed open).
Tests added/updated across all of the above.
The big win the pipeline missed: projectProfile + agentInstructions doc dumps
(~14k chars) are L0-SYSTEM -> STATIC -> never pruned, re-sent verbatim every turn.
Now pruned via the same TokenPruner at a gentler ratio (keep 60% vs 45% freeform),
protected spans (code fences/paths/keys) kept so directives survive. Gated by
TOKEN_PRUNE (level 3+); base systemPrompt stays verbatim.
ContextSummarizedEvent (registered) keyed on stable session sequence, not the
ephemeral pack ordinal, so replay reuses the recorded summary artifact and never
re-calls the LLM (invariants #6/#8). TierContextSummarizer mirrors
JournalCompactionService for freeform context (tool outputs/docs/retrieved text)
the journal path doesn't cover. ContextState + DefaultContextReducer fold the
event; reducer replay-safety unit-tested.
FactSheet derives load-bearing spans (newest-first, capped) and pins them as an
L0 SYSTEM entry never dropped by the compressor (level 7). Event-derived each
assembly, not a persisted file, per invariant #1. Strict budget allocation
(level 9) compresses structured groups before freeform so conversation can't
starve tool logs / artifacts.
Root Child DOX Index assembled, plus a per-module AGENTS.md across the tree
(core/*, infrastructure/*, apps/*, testing/*, and docs/examples/frontend/etc),
each following the DOX section shape: Purpose, Ownership, Local Contracts,
Work Guidance, Verification, Child DOX Index.
Tool-calling loops were rendered as all-assistant-calls-then-all-tool-results
with the original task last, causing the model to re-issue the same tool call
indefinitely. Two stacked reorderings caused it:
- DefaultContextPackBuilder grouped entries by sourceType for per-type
compression, discarding a,t,a,t interleaving.
- PromptRenderer forced L1 (the live user turn) to render last, pushing the
task after the entire transcript.
- SessionOrchestrator's tool loop re-fed currentContext.layers.values.flatten()
(grouped by layer) each round, compounding the scramble.
Add a chronological `ordinal` to ContextEntry, stamped by the builder from
input order and restored after grouping/compression (the compressor preserves
entry identity, so ordinals survive). PromptRenderer now orders non-system
messages by ordinal, with the old L1-last layer priority kept only as a
tiebreak so router chat (ordinal 0) is unchanged. The orchestrator keeps a
running ordered accumulator instead of reading back the grouped pack.
Adds builder + renderer ordering regression tests.
P4-1: Wire steering to actually work (advisory-only):
- RouterFacade emits SteeringNoteAddedEvent via event store in STEERING mode
- SessionOrchestrator reads steering notes from event store and includes them
as ContextEntry objects (sourceType=steeringNote) in stage context packs
- Delete dead SteeringNote data class; single vocabulary = SteeringNoteAddedEvent
- Add optional validateSteering callback to DefaultRouterFacade for future
ValidationPipeline wiring (avoids cross-core dependency)
- Update RouterFacadeTest to assert event emission
P4-2: Router FACE — move hardcoded generation config:
- Add GenerationConfig field to RouterConfig with same defaults
- RouterFacade uses config.generationConfig instead of inline literals
- (Remaining P4-2 items: conversation persistence and coordination
semantics are design decisions requiring ADRs, deferred)
P2-1: Guard SessionId NPE with safe-call in SessionsReducer
P2-2: Remove 16 dead event classes + reducer branches; replace with live orchestration events in tests
P2-3: Standardize ChatInput divergences — guard CancelSession, single-arg ProtocolError
P2-4: Remove dead TuiToolRecord.diff and ToolDisplayStatus.REQUESTED
P2-5: Remove dead streamLive from SessionEventBridge
P2-6: Extract SessionsReducerContext data class for 6+ param method
P2-7: Replace StageId("none") sentinel with TypeId.NONE
P2-9: Add TypeId.random() factory on all type-alias IDs
P2-10: Add KDoc on schemaVersion documenting reserved-for-migration
P2-8: Verified RouterReducer string-template already correct (TypeId value class toString)
- GlobalStreamHandler.handleCreateGrant validates scope (SESSION/STAGE)
and sends ProtocolError to client on validation failure instead of
silent log.warn + drop.
- Derive event stageId directly from GrantScope type, removing
redundant stageIdForEvent tuple.
- SessionOrchestrator integrates ApprovalEngine to check active grants
before requesting user approval for T2+ tool calls.
- ContextEntry gains EntryRole (SYSTEM/USER/ASSISTANT/TOOL) field for
proper chat message role mapping.
- RouterContextBuilder.build is now suspend; uses Tokenizer for
accurate token estimation with fallback to character-based estimate.
- LlamaCppInferenceProvider maps EntryRole to ChatMessage role instead
of heuristic layer-based inference.
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
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.
