After a freestyle plan compiles successfully, requestPlanApproval is invoked
before ExecutionPlanLockedEvent is emitted. Rejection emits
ExecutionPlanRejectedEvent(source="operator") with no lock and no phase-2 run.
Adds public SessionOrchestrator.requestPlanApproval seam delegating to
requestStageApproval, wired in Main.kt. Two new tests cover the reject and
approve paths; existing tests stay green via the default passthrough param.
emitLlmArtifacts previously emitted ArtifactCreated/Validating/Validated for every
llm-emitted slot unconditionally, fabricating "validated" artifacts when the model
produced no content. Gate now mirrors the F-015 file_written check: slots with null
or blank cached content are skipped with a warn log. Regression test added in
NeedsArtifactInjectionTest verifies no artifact events appear for a blank-response stage.
Follow-ups spotted while fixing the artifact-content bug:
- #1 robustness: listArtifacts resolves content via runCatching, degrading to null
instead of failing the whole listing on one bad CAS read (resolveContent helper)
- #2 eviction visibility: WARN when a referenced artifact hash resolves to null
(most likely evicted/compacted while still referenced by the event log)
- #3 ordering trap: document on ArtifactCreated/ArtifactContentStored that 'Created'
fires at validation, AFTER ContentStored at inference — the latent fold hazard
- #4 reopen gap: SessionSnapshot now carries workspaceRoot (derived from
SessionWorkspaceBound), so a reopened session restores its workspace label
- #5 orchestrator headroom: isBackEdge externalised to a top-level function so
DefaultSessionOrchestrator drops below the TooManyFunctions threshold (was at it)
#6 (orphaned empty F-010-era artifacts) needs no code change — empty content is
already normalised to null ('(no content stored)'); emission is prevented going
forward by the shipped F-010/F-018/F-020 fixes.
Implements the replay-safe half of preemptive redirect (graph re-routing). An
operator-confirmed PreemptRedirectEvent overrides the resolver's edge at the next
transition boundary; the pure resolver stays untouched.
- PreemptRedirectEvent / PreemptRedirectBlockedEvent (+ serialization registration)
- TransitionExecutedEvent + TransitionDecision.Move gain optional redirectId — the
durable 'consumed once' marker
- PreemptRedirect.decide: pure decision over the event log (override / block / none),
so replay reaches the identical outcome without re-classifying (invariant #8)
- override wired in DefaultSessionOrchestrator.step above resolveTransition; back-edge
jumps count against the existing maxRetries cap via executeMove
- blocks jumps to unknown stages or targets with unsatisfied needs
- DomainEventMapper: redirect events mapped to null (operator surface ships with the
LLM-proposal + approval-confirm front-half)
- tests: override+consume-once, block-on-needs, block-on-unknown, ignore-consumed
Front-half (LLM proposal -> approval-gate confirm -> emit PreemptRedirectEvent) is
deferred; needs live LLM verification. Until it ships no redirect event is emitted in
production, so the override is inert. Spec: docs/plans/2026-06-10-freestyle-graph-rerouting.md
- generic SystemResourceProbe: owner-agnostic /proc/meminfo system RAM
overlaid on the vendor GPU probe, wired on both managed and static paths
so the VRAM/GPU/RAM gauge renders with an external llama-server (was dormant)
- F-002: classify provider 4xx (e.g. llama.cpp 400) as terminal, not retryable
(except 408/429); stops retrying deterministic request failures to exhaustion
- F-003: FileSystemPromptLoader expands leading ~ / ~/ to user home
- F-004: map InferenceFailedEvent + RetryAttemptedEvent to new
ServerMessage.InferenceFailed / RetryAttempted, decoded+rendered in tui-go;
ArtifactContentStoredEvent explicitly mapped to null (internal, no warn)
- tests: tilde expansion, SystemResourceProbe (static/managed/fail-soft)
Two operator features over the existing WebSocket protocol, plus a tui-go nav fix.
Config editor (g / palette "config"):
- core:config gains a thin registry stack: OrchestrationKnobs ([orchestration]
block), CorrexConfigWriter (round-trip TOML serializer; parseToml(write(c))==c),
ConfigHolder (AtomicReference live config), and EditableConfig (allowlist of
editable fields + patch applier; security fields are absent so they can never
be patched).
- ConfigService validates -> persists (atomic temp+move) -> swaps the holder ->
rebuilds config-derived services. Live-apply is scoped to safe seams: stage
timeout, compaction threshold (now a supplier), router knobs (routerFacade
rebuild), and personalization/project toggles all take effect on the next
session/turn; in-flight sessions keep the config they started with.
server.host/port are persisted + badged "restart required", not hot-swapped.
- Protocol: GetConfig / UpdateConfig / ConfigSnapshot; TUI overlay with
type-aware editing (bool toggle, enum cycle, inline int/string edit) and save.
Artifact viewer (v / palette "artifacts"):
- Server assembles a session's artifacts from the event log and resolves bytes
from the CAS store (StreamQueries.listArtifacts) — a replay-neutral snapshot
read. TUI overlay lists artifacts and shows scrollable content.
tui-go fix: workflow failure no longer clears selectedID (which yanked the user
to the list); listNav lands on the first session when nothing is selected
instead of wrapping to a random one.
Config is not event-sourced (it lives in TOML); editing stays outside the log.
rehydrate() now scans ArtifactContentStoredEvent (the durable slot->CAS-hash
bridge) and fetches stored bytes by content hash, keying the cache by the
logical slot name. The slot name is never passed to the hash-keyed CAS, so the
odd-length-hex crash is gone and artifact content is restored on cold-start
resume. RehydrateTest reworked to use a content-addressed fake store (slot name
!= content hash) so it actually exercises the bug. Replay (#8) is unaffected —
rehydrate is live-resume-only.
Also bump router narration maxTokens 1024 -> 4096: reasoning models were
spending the whole budget thinking and emitting empty content (finishReason=
length), so narrations never reached the TUI.
Removes the stale TUI-refactor progress doc.
Live QA audit of role_pipeline against a sample repo surfaced and fixed a
chain of defects that prevented any tool+artifact workflow from running
end-to-end. The pipeline now completes cleanly with a real, validated,
reviewed file change.
- F-008 workflow: propagate stage token_budget -> generationConfig.maxTokens
(TomlWorkflowLoader) so large stages stop truncating at the 2048 default.
- F-009 tools/kernel: file_read missing-file is recoverable; recoverable tool
errors feed back into the loop instead of aborting the stage.
- F-010/F-018 kernel: reject premature stage_complete and nudge the model to
emit the owed artifact / invoke a write tool (bounded by MAX_TOOL_ROUNDS).
- F-011 schemas: list-typed artifact fields string -> array (analysis/design/
impl_plan) to match model output.
- F-012 kernel: strip an outer markdown code fence from LLM artifacts.
- F-013 validation: payload-validation failures are retryable; structural
failures stay terminal (wires the invariant-#7 reject+retry contract).
- F-014 tools: file_edit schema matches its real params; edits emit a diff.
- F-015 kernel: record tool-execution events + materialise a real file_written
artifact from the on-disk write; gate validation so a no-write stage cannot
be rubber-stamped (no more false-success runs).
- F-016 server: raise stageTimeoutMs 60s -> 180s for slow local models.
- F-019 artifacts/kernel: file_written artifact carries the unified diff so the
reviewer can verify the change (shared DiffUtil; file_write emits a diff too).
- F-020 tools: model-correctable file_edit failures are recoverable + steer
toward replace/file_write over the fragile patch op.
Full findings register (F-001..F-021, incl. open F-021 resume rehydrate bug)
in qa/audit-report-2026-06-08.md. All module tests green.
ArtifactPayloadValidator passed the logical slot name into the
content-hash-keyed CAS store, crashing every workflow with a typed
produces slot. Validator now reads payloads from a content map threaded
through ValidationContext (populated from the orchestrator's per-session
artifact cache across all stages) and no longer depends on ArtifactStore.
Also records the slot->CAS-hash mapping as a new ArtifactContentStoredEvent
(registered for serialization), emitted at both CAS write sites, so
artifact content is recoverable from CAS by hash after a cold start.
Records operator profile as a snapshot event at session start (invariants #8/#9),
populates SessionState.boundProfile via reducer, and injects the about text as a
pinned L0 SYSTEM context entry in every stage. Gated by PersonalizationConfig.enabled.
Extract a SubagentRunner fun-interface (SubagentRunRequest/SubagentRunResult)
and an InSessionSubagentRunner default that delegates to the existing
executeStage path, with per-run effectives captured in the lambda closure so
the seam stays free of the internal RunEffectives type.
DefaultSessionOrchestrator.enterStage now dispatches through subagentRunner.run
instead of calling executeStage inline; effectives threading is dropped from
run/step/executeMove/enterStage/resume. ReplayOrchestrator supplies its own
runner. Behaviour is identical — RefinementLoopTest and full check stay green.
Stages declaring needs=[...] now receive each needed artifact's validated
JSON (from artifactContentCache) as an L1/USER neededArtifact context entry,
so a one-shot subagent sees its inputs.
Also emit llm-emitted artifact lifecycle events (Created/Validating/Validated)
on successful validation via emitLlmArtifacts, closing a latent gap where
verifyProduces would fail for stages producing only an llm-emitted artifact.
Events are emitted only after validation passes, preserving invariant #7.
Two issues surfaced during live QA once workflows began progressing past the
first stage:
1. Narration prompts went out with no user message, so the chat template
rejected them ("No user query found in messages"). buildNarrationContext
filed the trigger instruction (a user turn) under ContextLayer.L0, and
PromptRenderer folds every L0 entry into the system message regardless of
role. Move the trigger to L1 so it renders as the user turn.
2. TransitionExecutedEvent was emitted after the next stage had already run:
executeMove called enterStage (which executes the stage) before advanceStage
(which emits the transition), so the event log showed a stage running before
the event marking entry into it. Emit the transition before entering.
Adds a regression test asserting a rendered narration prompt carries a user
message.
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.
Wires the workspace handshake end to end so a session's workspace is bound
from the client's cwd at connect time and is event-sourced for replay.
- Go TUI sends Hello{workingDir=os.Getwd()} as the first WS frame on connect
(protocol.go encoder + client.go connect path; golden test pins the wire
format against the Kotlin discriminator).
- Server adds ClientMessage.Hello, stashes the per-connection workingDir, and
on session start resolves it through WorkspaceResolver's trust pipeline,
emits SessionWorkspaceBoundEvent (invariant #9), and threads the resolved
workspace into OrchestrationConfig for the live run. A Hello after the first
StartSession is ignored (warn); a rejected path binds the resolver fallback.
- Replay derives the workspace from the recorded event: SessionState gains
boundWorkspace, DefaultSessionReducer fills it from SessionWorkspaceBoundEvent,
and ReplayOrchestrator uses it (Path.of only, no filesystem re-query —
invariant #8) with graceful fallback to config for pre-Phase-B logs.
Absent Hello / null resolver degrades to the prior config-workspace behavior.
A stage's allowedTools only shaped which tool definitions were offered to
the model; the dispatch path resolved returned tool calls straight from the
full registry and executed them without checking stage membership. A
hallucinated, jailbroken, or edited-transcript tool call for any registered
tool would run unchecked (violating invariant #5 / policy-is-absolute).
dispatchToolCalls now rejects any tool call whose name is not in the stage's
allowedTools (STAGE_COMPLETE_TOOL exempt), emitting ToolExecutionRejectedEvent
and feeding an error ContextEntry back to the model instead of executing.
Empty allowedTools means deny-all domain tools, consistent with offering
only STAGE_COMPLETE_TOOL at inference time.
A steering note attached to a tool approval was recorded but only
consumed by the NEXT stage's prompt build (buildSteeringNoteEntries runs
once, before the tool loop), so on a single-stage task it had no visible
effect. Two changes:
- Approve+note: capture userDecision.userSteering at the gate and inject
it as a context entry right after the tool result, so the same stage's
loop re-infers with the note and the model acts on it.
- Reject: buildSteeringNoteEntries now also emits anti-repeat feedback for
REJECTED decisions with no note, so the model does not re-propose the
identical call on the retryable re-run (a bare reject previously fed
back only "approval denied").
Integration test drives an approval with a steering note and asserts the
next inference's context carries it.
Compute the effective tool registry/executor and plane-2 WorkspacePolicy per run
from config.workspace (effectivesFor), threaded through the orchestrators; a null
workspace falls back to the boot instances byte-for-byte. Wire the concrete
WorkspaceToolRegistryProvider in Main (buildToolConfigForWorkspace). Session undo
unions the session's recorded workspace into its jail roots. (Axis 2 Phase A, tasks 3 + 7.)
Add a WorkspaceContext value type and a nullable OrchestrationConfig.workspace,
plus SessionWorkspaceBoundEvent registered in eventModule. Purely additive; no
behavior change when workspace is null. (Axis 2 Phase A, tasks 1-2.)
A stage declaring no `produces` passed verifyProduces vacuously, letting an
agent stage_complete with zero work. Gate on allowedTools: a produce-less stage
with tools available must have >=1 ToolInvocationRequestedEvent scoped to its
stageId, else Failure(retryable). Produce-less + no tools is exempt (only
stage_complete is ever offered), so pure-reasoning stages aren't bricked.
DefaultContextPackBuilder already enforced the token budget, but SessionOrchestrator discarded the entriesDropped signal at both build sites — overflow was enforced yet unobserved. Emit ContextTruncatedEvent when entriesDropped>0, matching the router path (open-threads 6.2 contract).
- LlamaCppInferenceProvider: check HTTP status and surface the real error body instead of masking it as a ChatCompletionResponse deserialization failure
- PromptRenderer: render the live conversation layer (L1) last so the user turn is the final message (fixes Qwen 'No user query found' 500 when L3 recall is present)
- TomlWorkflowLoader: resolve stage prompts relative to the workflow file's own dir (bundle), CWD-independent; config-dir fallback for globals
- SessionOrchestrator: hard-fail a stage whose declared prompt can't resolve (was a silent user-less request)
- move healthcheck prompts next to the example workflow (examples/workflows/prompts/)
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).
Tools can declare how their output is compressed before it enters the
context pack, replacing uniform handling. Open-threads 6.3 / ADR-0003.
- core:tools/compression: ToolOutputCompressor interface,
IdentityCompressor default, declarative OutputCompressionSpec +
CompressionRule (StripBlankLines, StripLeadingWhitespace,
DropMatching, HeadTail), and the pure DeclarativeCompressor engine
(regexes compiled at construction; bypassOnError passes raw on
non-zero exit; never throws on input).
- Tool gains `outputCompressor` (default IdentityCompressor). FileReadTool
strips blanks + leading whitespace; ShellTool strips blanks + head/tail.
- SessionOrchestrator applies the resolved tool's compressor on the
ToolResult -> ContextEntry path only. Raw output stays authoritative
in the event log (invariant #6); compression is a pure function of
(raw, exitCode, spec), so no new event and replay stays deterministic.
- Spec is @Serializable/config-shaped (JSON round-trip tested). No
custom-tool-from-config path exists today, so first-party tools wire
in code; TOML-declared compression rides along when that path lands.
Tier B (format-aware parsers: failures-only test output, git-log oneline)
is a documented per-tool extension behind the interface, not built here.
Add ParamRole and a defaulted Tool.paramRoles to the tool contract; built-in
tools declare which params carry effects: file_read/write/edit -> path=PATH,
shell -> argv=EXEC_COMMAND. PathContainmentRule / ExecInterpreterRule /
NetworkHostRule now inspect only the declared params when roles are present, and
fall back to the looksLikePath / leading-token / extractHost heuristic only for
un-enriched (e.g. custom) tools - so a custom FILE_WRITE tool is still
containment-checked. Shared extractParamStrings flattens String and List<*>
(argv) values. SessionOrchestrator.runPlane2Assessment resolves the tool once
and passes tool.paramRoles into the assessment input.
This retires the arg-guessing from the first-party path: a slashy edit 'content'
arg is no longer mis-flagged as a path.
Implements the full vertical slice for invariant #9 tool-call assessment:
- core:toolintent — new module with ToolCallRule seam, ToolCallAssessor,
WorldProbe/FileSystemWorldProbe, WorkspacePolicy, PathContainmentRule,
and RiskMapping (assessment → RiskSummary / AssessedIssue)
- core:tools — ToolCallAssessmentRecord + ToolInvocationRecord.assessment
field; DefaultToolReducer handles ToolCallAssessedEvent (replay proof)
- core:config — ToolsConfig gains workspaceRoot + privilegedLocations;
ConfigLoader parses both; DEFAULT_PRIVILEGED_LOCATIONS built-in
- core:kernel — OrchestratorEngines gains toolCallAssessor/workspacePolicy/
worldProbe fields; SessionOrchestrator.dispatchToolCalls runs
runPlane2Assessment before the tier gate: BLOCK → hard-reject without
executing; PROMPT_USER → elevates tier into approval path with plane2Risk
in the ApprovalRequestedEvent
- apps/server — constructs PathContainmentRule + ToolCallAssessor +
WorkspacePolicy from config and wires them into OrchestratorEngines
Assessment is recorded as ToolCallAssessedEvent (environment observed once,
facts stored, replay reads events — invariant #9). Assessor and WorldProbe
are only invoked on the live orchestrator path, never in replay.
Carry the full RiskSummary (level, signals, rationale) inline on
ApprovalRequestedEvent instead of discarding it after assessment. The two
server-side DTO builders (live ApprovalCoordinator path and replay
DomainEventMapper path) now render real risk level, recommended action,
signal factors, and the [code] rationale lines into the approval WebSocket
message, with a consistent enum-name fallback when no assessment ran (tool
path). RiskSummary/RiskSignal made @Serializable for event embedding;
shared RiskSummary.toDto() lives next to RiskSummaryDto.
Flags when a workflow stage's allowedTools references a tool name that
is not registered in the tool registry (config drift), surfaced as a
non-blocking WARNING.
- Add ValidationContext.availableTools (nullable; null = registry
unavailable, skip the check)
- MissingToolRule emits one MISSING_TOOL warning per (stage, tool) pair,
deterministically ordered
- Populate availableTools from the ToolRegistry at the orchestrator
construction site; wire the rule into the prod SemanticValidator
Extract message-rendering logic from LlamaCppInferenceProvider into a
provider-agnostic PromptRenderer in core:inference. SessionOrchestrator
now serializes the rendered ChatMessage list as JSON for the prompt
artifact, so the audit trail reflects what the LLM actually saw.
Resolves the TODO at SessionOrchestrator.kt:691.
- Add STAGE_COMPLETE_TOOL constant and meta-tool handler in executeStage
loop: when LLM calls stage_complete, break out of tool dispatch loop
and proceed to normal validation/transition
- Inject stage_complete tool definition in every inference request so
the LLM always has the option to signal stage completion
- Replace expand-all diff with scrollable diff window in approval
surface (ctrl+x toggles, up/down scrolls, shows line range)
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)
P1-1: Replace check-then-act with computeIfAbsent for activeSessionJobs to
prevent double-launch. Register pendingApprovals[requestId] BEFORE emitting
ApprovalRequestedEvent to close the approve-before-register window.
P1-2: ToolCompleted with a diff now appends msg.diff to routerMessages
instead of the static "--- diff from $toolName ---" marker.
P1-3: Change routerMessages from List<String> to Map<String, List<String>>
keyed by sessionId.value. RootReducer appends to the correct session's list;
RouterPanel renders only routerMessages[selectedId].
P1-4: On IDLE chat submit, SessionsReducer creates an optimistic
SessionSummary(status="STARTING") and sets selectedId.
processSessionStartedMessage removes any STARTING session and inserts the
real one on echo. RootReducer sets sessionEntered=true for the optimistic
session.
Tests: LaunchRegistrationRaceTest, ApprovalRegisterBeforeEmitTest,
RootReducerTest (diff/per-session/isolation/optimistic-submit),
SessionsReducerTest (optimistic/reconciliation). All P0/P1 tests pass.
./gradlew check green.
- Fix duplicate inference requests after approval resume by registering orchestrator
jobs in activeSessionJobs (ServerModule.launchSessionRun), so the guard in the
OrchestrationResumedEvent subscription prevents spurious duplicate resume.
- Replace blocking Files.readString in computeToolPreview with withContext(Dispatchers.IO)
by making the function suspend — no blocking I/O on the coroutine dispatcher.
- Guard orderedIds.add() in rebuildTools against duplicate invocation IDs on replayed
ToolInvocationRequestedEvent to prevent duplicate tool records in snapshots.
- Add unified-diff preview for file_write tools: computeToolPreview reads existing
file and generates ---/+++ diff before emitting ApprovalRequestedEvent.
- Render diff preview with color coding in ApprovalSurface (@@ yellow, +/- green/red).
- Include current-stage tool records in SessionSnapshot via rebuildTools event replay.
- Fix RouterContextBuilderTest: recursive buildPack helper and 2 tests using class-level
builder instead of their local builder instances (conversationKeepLast mismatch).
- Add suspend keyword to RouterFacadeTest mock, fix buildPack recursion.
- 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.
Three coordinated changes:
1. DefaultOrchestrationReducer now handles TransitionExecutedEvent,
updating currentStageId so the projected state always reflects the
actual current stage rather than staying stuck at the start stage.
2. DefaultSessionOrchestrator.resume() re-enters the execution loop at
the current stage without re-emitting WorkflowStartedEvent. It reads
currentStageId from the projected state, creates an ExecutionContext
there, and calls enterStage → step exactly as run() does after its
first stage.
3. ServerModule.start() calls resumeAbandonedSessions(), which scans all
RUNNING/PAUSED sessions on startup and launches resume() for each one
whose orchestrator is no longer in memory. Sessions that have a live
deferred are unaffected; only sessions with no coroutine (e.g. the
server was restarted while a tool was executing or approval was pending)
are picked up and re-executed from their current stage.
