Stage agents were spending most of their turn budget re-discovering files
already known from prior stages/attempts. Root cause: nothing durable carries
acquired knowledge across handoffs and retries. First four slices of the fix:
- core:sourcedesc — new dependency-free module: describe(path, bytes) derives
comment-free structural navigation metadata (module, bounded symbols, bounded
imports, versioned format). Deliberately non-prose: descriptors are derived
from agent-writable files and rendered into successor-stage context, so
comments/docstrings/literals are excluded to close a prompt-injection channel.
CAS post-image hash stays authoritative; descriptor is disposable navigation.
- kernel retry-repair state (ContextFeedback): on retry, name the authoritative
CAS images of files this stage already wrote so the agent patches them instead
of re-reading to rediscover them.
- kernel file-written manifest (SessionOrchestratorArtifacts): each produced
file surfaced with its authoritative CAS image plus a comment-free structural
descriptor (via core:sourcedesc, over recorded CAS bytes — replay-safe).
- apps/server RepoMapIndexer: route the injected repo-map descriptor through the
comment-free describe(). Previously scraped leading comments, which were
embedded into L3 and surfaced verbatim to successor stages — an injection
channel from one stage into the next. Structural facts (module + imports +
symbols) remain as the retrieval signal.

Discovery-stage clarifications could only be answered over WebSocket
(ClientMessage.ClarificationResponse), so the curl-based headless QA
driver parked forever at discovery.
Add POST /sessions/{id}/clarify mirroring approveStageRoute. The server
resolves the live (stageId, requestId) from the session id via
SessionOrchestrator.pendingClarificationFor() — the newest still-live,
unanswered ClarificationRequestedEvent from the event log — so a curl
caller need not know the requestId. Empty answers = free-text skip.

A plan that failed grounding used to dead-end — every gate rejection in
FreestyleDriver.lockAndRun was terminal, so a legitimate grounding catch
(e.g. a stage declaring a PROJECT build with no manifest) left the run stuck
with no retry.
lockAndRun is now a gate loop: on a grounding rejection with retries left it
re-runs the planning workflow from the architect stage (rerunArchitect), which
emits a corrected plan, then re-gates. Other gate failures — and grounding once
maxGroundingRetries is spent — stay terminal.
- FreestyleDriver: gate loop + rerunArchitect/maxGroundingRetries seams;
groundPlan returns findings (String?) instead of Boolean; post-grounding
tail extracted to lockAndRunGrounded.
- DefaultSessionOrchestrator.runFrom(startStage) + emitWorkflowStarted(startStage);
run() delegates to it. Lets the re-run enter directly at architect.
- buildGroundingFeedbackEntry (ContextFeedback) injects the already-recorded
PlanGroundingEvaluatedEvent findings into the architect's L1 context on re-run;
wired in SessionOrchestratorExecution.
- Main: rerunArchitect lambda (rehydrate -> runFrom(architect) -> rehydrate).
The architect stage-entry approval gate already reuses a prior APPROVED decision
(alreadyApproved), so the re-run does not re-prompt the operator — added a
FreestyleApprovalGateTest regression guard proving runFrom(architect) with a
seeded approval emits no second request and runs straight through.
Tests: FreestyleDriverTest retry-then-lock + exhaustion->reject(source=grounding);
FreestyleApprovalGateTest reuse-approval guard.

This branch's uncommitted WIP, committed together (entangled at file level).
Distinct pieces of work:
Freestyle QA fixes (this session):
- FileEditTool: pre-validate replace anchor in validateRequest — reject a
missing/ambiguous target BEFORE the approval gate, mirroring read/write's
file-not-found / read-before-write pre-checks. Shared not-found/ambiguous
messages between validate and execute so they can't drift.
- PlanGrounder: add `scanned` flag; when no RepoMapComputedEvent was recorded,
repoMapPaths is "unknown" not "empty workspace" — skip scope grounding
(which proves a path ABSENT) so real paths (apps/server/**) aren't falsely
rejected. Build-manifest check still runs.
- FreestyleDriver: wire scanned=(repoMap!=null); on plan rejection emit a
session-terminal WorkflowFailedEvent so a rejected run reads FAILED, not the
COMPLETED-lie (last verdict was the planning-phase WorkflowCompleted).
- ServerModule: resolve project-memory workspace root from the session's bound
workspace (sessionWorkspaceRoot) instead of boot-static pm.repoRoot(), fixing
the workspace-binding divergence (correx vs empty scratch dir). Retire tracked
in Vikunja #266.
- LaunchRegistrationRaceTest: join registered jobs before asserting launchCount
— computeIfAbsent returns the Job immediately but the fire-and-forget launch
body lagged awaitAll (the 49-vs-50 flake).
ACR concept-compiler experiment (pre-existing WIP on this branch):
- ExecutionPlanCompiler/Model/PlanLinter, #264 needs-seam (sessionArtifacts),
LSP diagnostics subsystem (LspDiagnosticEvents/Runner/Lsp4j), BootWorkspace,
config surface, workflow prompts/schemas, orchestrator advance-don't-rerun.

codebase-memory search tools failed 9/9 ("project not found or not indexed")
because index_repository was never called for the repo. After MCP servers
mount, if one advertises index_repository, invoke it once with the workspace
root (repo_path) through the normal ToolExecutor path, on a background daemon
so a slow index doesn't block startup. "fast" mode to reach usable quickest.

SessionStreamHandler.handle() already registers the connected socket into
ApprovalCoordinator's per-session client map before entering the inbound
read loop, and ApprovalCoordinator.broadcast() (fed by ServerModule.start()'s
live subscribeAll().filter{ApprovalRequestedEvent} subscription) already
targets that map — so a gate firing after connect does reach the socket,
and CLI --auto-approve is not actually blind. Add integration coverage
(none previously existed for SessionStreamHandler) proving: (1) a live
ApprovalRequired fired post-connect reaches the socket, and (2) a
disconnected client is cleanly deregistered without disrupting delivery
to a later client on the same session — covering the 8d7c827e non-blocking
emit and 3559ea67 cleanup-on-termination invariants.

Adds an MCP host layer so external MCP servers (AST/LSP code-intelligence,
package resolvers, etc.) can be mounted at startup and surface their tools/list
as first-class Correx tools named mcp__<server>__<tool>. Each MCP tool is a
Tool+ToolExecutor, so it rides the normal ToolExecutor path and inherits tier
gating, receipts, and event-recorded execution (#5) with zero special-casing;
replay reads the recorded receipt rather than re-calling the server (#8/#9).
- McpProtocol/McpStdioClient/McpTool/McpMounter in infrastructure:tools
(stdio JSON-RPC 2.0, tools/* slice only). Capabilities empty; safety via
default T2 tier since external side effects are opaque.
- [[mcp]] config (id/command/env/tier) + array-of-tables parsing.
- Main wires mounted servers into extraTools (main + per-workspace paths) with
a shutdown hook; a server that fails to start is logged and skipped.
- Tests: in-process fake transport (handshake/list/call/error + tool mapping),
[[mcp]] parser.

Vikunja #167/#168/#169.
#167 PlanGrounder (infrastructure/workflow): build-prereq + touches-scope
existence grounding, emits PlanGroundingEvaluatedEvent. Deterministic fold
over recorded workspace/plan events (invariants #8/#9).
#168 positive-pattern mining (SessionOrchestratorPlanPatterns): mine
SuccessfulPlanShape from cross-session log — a locked plan whose own
workflow later completed — and inject the closest-resembling plan shape as
L0/SYSTEM advisory context for the planning stage. Keyword-Jaccard
resemblance, no LLM/embedder, replays identically. Advisory only (#3).
#169 stage-prompt audit + CORREX_STAGE_GUIDANCE ON/OFF toggle in
SessionOrchestratorExecution. RunCommand gains --intent to seed a
freestyle session over REST.
Also: workspace verification events + concept-compiler wiring. ./gradlew
check green.
Promotes recurring validated failure->fix patterns into L3 as retrieval-on-demand
concepts. Deterministic core: ConceptCompilerProjection clusters
RetryAttempted->StageCompleted pairs by fingerprint (gate-agnostic), promotes at
N=3 cross-session validated fixes, never-contradicted. ConceptPromotedEvent is the
sole authoritative write (idempotent under replay); ConceptCompilerService appends
it + best-effort injects to L3 (non-authoritative, inv #6). Wired live in
ServerModule.start() on StageCompleted.

Claude-Session: https://claude.ai/code/session_01DhFXmKe4WisSSPf9LrmmTg
Tool results injected into model context are now consistently framed and
globally bounded. Success output over the floor (TOOL_RESULT_MAX_CHARS=8000)
is head/tail-truncated with a marker naming a retrieval ref; the full raw
output spills to the artifact store (CAS) and its hash is recorded on the
ToolReceipt (fullOutputHash) in the event log. Agents recover the full text
via the new read-only tool_output(ref=...) tool.
- SessionOrchestrator: frameTruncatedToolResult + renderToolResult; char-cap
head/tail so a single pathological long line can't defeat the bound.
- ToolReceipt.fullOutputHash (additive, nullable).
- ToolOutputTool (Tier T1, no fs capability) resolves ref -> full bytes.
- Wired via extraTools in Main.kt; tool_output added to ALWAYS_AVAILABLE_READ_TOOLS.
- Failure path keeps ERROR:/FATAL: prefixes (all-rejected breaker dependency).
Tests: FrameTruncatedToolResultTest, ToolOutputToolTest.
DomainEventMapper.kt had grown into a single ~280-line `when` over every
domain event type with a ~40-line flat import list ('god mapper' smell).
Split the when body by domain area into four files, each a suspend fun
returning a MapOutcome sentinel:
- SessionEventMappers.kt — session/workflow lifecycle + chat turns
- StageInferenceEventMappers.kt — stage transitions + inference lifecycle
- ToolEventMappers.kt — tool exec/assessment + review findings (+ prettyToolParams)
- LifecycleEventMappers.kt — approval/clarification/proposal/narration/artifact/model/preempt
The dispatcher chains them; MapOutcome.Emit(msg?) vs MapOutcome.Skip
preserves the null-vs-unhandled distinction (a suppressed event like
ArtifactValidating returns Emit(null), not Skip). Public entry points
(DomainEventMapper class, domainEventToServerMessage, prettyToolParams)
unchanged — no behavior change, pure maintainability. Each per-domain
import list is now local to its file. DomainEventMapperTest green.
Vikunja #31.
GenerationConfig only carried temperature/top_p/max_tokens/stop/seed. Added nullable
topK/minP/repeatPenalty, serialized to the llama.cpp and OpenAI-compat request bodies
via @EncodeDefault(NEVER) so an unset knob is omitted (the model keeps its own default)
and behavior is unchanged unless the operator opts in.
Surfaced as a new [sampling] config section feeding the default stage GenerationConfig
(the main agentic loop) through TomlWorkflowLoader + ExecutionPlanCompiler; the former
hardcoded temperature=0.7/topP=1.0 stage defaults now come from config. Talkie
chat/narration keep their own generation settings.
Vikunja #46 (task 76) — sampling half.
The kernel's ReAct-loop tuning constants (max tool rounds, read/rejection-loop
nudge thresholds, feedback issue cap, repo-map top-k/files-per-dir, docs catalog
cap, clarification-round cap, review-block confidence/retry cap, default
refinement, recovery/intent route budgets) were hardcoded in SessionOrchestrator/
DefaultSessionOrchestrator. Relocated to a new OrchestrationTuning value threaded
through the orchestrator constructor, mapped from CorrexConfig.orchestration in
Main.kt, parsed in ConfigLoader, written by CorrexConfigWriter. Defaults equal the
former constants so an absent [orchestration] section reproduces prior behavior.
Startup-load (not hot-reload); pure output-truncation caps left as constants.
Vikunja #46 (task 76).
Two event-delivery back-pressure faults from the core audit (#7).
(a) streamGlobal forwarded globalFlow → a per-connection Channel with
buffer.send (SUSPEND). globalFlow is also SUSPEND-overflow, so one wedged
WebSocket client back-pressured globalFlow → append() suspended → the whole
kernel stalled. Now the collector uses trySend; on overflow it closes the
buffer with SlowClientException, tearing down that one connection (client
reconnects and re-syncs via replaySnapshot) instead of blocking append().
(b) Per-session subscriptions (extraBufferCapacity 64) used tryEmit with the
return ignored: a lagging in-process collector (e.g. LiveArtifactRepository)
silently diverged from the durable log. Both SqliteEventStore and
InMemoryEventStore now warnIfDropped() — the event is still persisted; only the
live SharedFlow drops, and we surface it. ponytail: log-only; bounded
rebuild-on-lag if divergence ever bites.
Added slf4j-api to :infrastructure:persistence (already the standard logging
dep across modules) for the warn.
Green: :infrastructure:persistence + :apps:server compile+detekt+test (the one
pre-existing ModelLifecycleWiringTest failure needs a real llama-server, fails
identically on clean checkout).
Two unbounded per-session leaks that never released after a workflow ended:
- SessionOrchestrator.artifactContentCache (full file contents, keyed
"<sessionId>:<path>") grew for the process lifetime. Added
evictArtifactContentCache(sessionId) — session-prefix key removal,
rehydrate-safe — called on both completeWorkflow and failWorkflow.
cancellations was already evicted on both terminal paths.
- NarrationSubscriber leaked a Channel + worker coroutine + lanes map entry
per session forever. closeLane() now closes the lane channel on
WorkflowCompleted/WorkflowFailed (draining the terminal narration first);
the worker self-removes from lanes when its for-loop exits on close.
Deferred: SqliteEventStore.subscriptions eviction — removing the SharedFlow
mid-life would strand LiveArtifactRepository's downstream collector (a
suspended-coroutine leak worse than the tiny empty-SharedFlow entry).
Green: :core:kernel compile+detekt, :apps:server *NarrationSubscriber* (8).
S5 — GET /sessions re-read + re-projected every session's full log on every
call. Cache keyed on eventStore.lastGlobalSequence(); volatile pair-swap,
no lock — any append bumps the seq so a stale read is impossible.
S6 — close research + health-probe HttpClients via shutdown hook; log the
real configured host:port (was hardcoded 8080) and bind to it; System.err
-> SLF4J; WARN at startup on non-loopback bind (unauthenticated surface).
resolveApiKey precedence item N/A — no such code exists.
Both verified green in isolated worktrees (226 pass). Full local build
currently blocked by an unrelated concurrent core:config edit.
SessionEventBridge.replaySnapshot ran per WS connection and appended a repair
OrchestrationResumedEvent — a write side effect on a pure read path that two
concurrent clients could double-append (and 'open TUI' mutated replay history).
Moved to a one-shot ServerModule.repairStuckApprovalPauses() at boot; replaySnapshot
is read-only again. The state it repairs comes from a fixed pre-Feb-13 bug, so no
session newly enters it at runtime — boot coverage is sufficient.
Note: :apps:server:test not run (core:kernel broken by concurrent work); edits are
isolated and mirror the existing preRegisterPendingApprovals shape.
broadcast() wrapped each client.send in a bare runCatching with no logging or
dead-client eviction, so an approval prompt could vanish silently and the session
hang until reconnect. Now log+evict failed clients from both registries and error
when a prompt reaches 0 live clients.
Note: :apps:server:test not run (core:kernel temporarily broken by concurrent work);
change is isolated, compiled clean before the breakage, detekt passes.
S7: DomainEventMapper mapped every non-APPROVAL_PENDING pause (CLARIFICATION_PENDING,
ABANDONED_STALE) to USER_REQUESTED, so clients rendered the wrong pause state. Added
the two PauseReason enum values, mapped the real reason string, and gave the Go TUI
distinct labels.
S8: REST POST /sessions launched a run without resolving/recording a workspace, so the
session had no SessionWorkspaceBoundEvent (path containment, project profile, grants had
nothing to anchor to). Extracted the WS path's resolve+emit into ServerModule.bindWorkspace
and called it from both launchers.
S1: ApprovalCoordinator marked a request resolved before submitApprovalDecision,
so a throwing submit left it permanently unanswerable; now resolve only on success
and clear the flag on failure so the client can retry. Recorded decision also used
a hardcoded Tier.T2 regardless of the real tier — now tracked per request.
S2: streamGlobal numbered live frames from a per-connection counter starting at 1,
colliding with the snapshot's lastSessionSequence (MAX(session_sequence)) after
reconnect and causing the TUI dedup filter to drop/misorder frames; now uses each
event's own persisted sessionSequence. Approval broadcast no longer sends 0.
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).
Adds the failure-ticket + recovery-routing mechanism: a deterministic
gate->capability table gates whether a stage has agency to fix its own
failure, opens a FailureTicketOpenedEvent when it doesn't, and routes to
a metadata role=recovery stage (per-stage budget, cap 2, not reset by
TransitionExecuted) instead of retrying in place. Extends salvage
decisions with a RECOVER option so the review-gate judge can also route
to recovery, unifies deterministic-gate and review-gate routing through
routeToRecovery(), and has ExecutionPlanCompiler synthesize a
write-capable recovery stage + edge for freestyle plans. Read-only tools
(file_read, list_dir) are now always available on any tool-granting
stage so a recovery stage can inspect the write-less stage's failure
without flooding context via shell ls -R.
A stage parked on operator clarification lost its modal whenever the
client disconnected or the server restarted — the questions were stranded
in the event log with no way to re-surface them (unlike approvals, which
already rehydrate).
Two composing mechanisms, mirroring the approval path:
- On reconnect: SessionEventBridge.replaySnapshot() now re-pushes the last
unanswered ClarificationRequestedEvent for a PAUSED/CLARIFICATION_PENDING
session as a ClarificationRequired message. Gated on the orchestrator
still holding a live deferred (SessionOrchestrator.liveClarificationRequestIds)
so a client never sees a modal whose answer could not be delivered.
- On restart: ServerModule.resumeAbandonedSessions() eagerly relaunches
clarification-parked sessions (approval-parked stay lazy). rehydrate+resume
re-runs the parked stage, which re-emits a fresh, live
ClarificationRequestedEvent (round budget MAX=3, 1 prior round recorded, so
it re-parks rather than silently proceeding), re-arming the deferred that
the reconnect path gates on.
pauseReason == "CLARIFICATION_PENDING" is the discriminator because the
reducer sets pendingApproval=true for every pause.
The clarification modal hard-truncated each question's head line with
clip(), so long prompts (e.g. an API question and an Architecture
question) were cut at the modal edge and unreadable. Wrap the prompt
across rows instead: wrapPrompt() greedily word-wraps with a narrower
first line (marker + header chip eat into it) and full-width
continuation lines, indented to align under the prompt.
Docs were indexed as up to 40 h1-h3 headings per .md (a TOC flood) and
force-fed or excluded wholesale by a binary docs gate. Replace with a
compact, always-on catalog the agent reads on demand.
- RepoMapIndexer: .md now yields ONE descriptor (frontmatter
description/summary/title -> first # H1 -> first prose line), not a
heading dump. Replay-safe (still List<String> symbols).
- SessionOrchestrator: always-on '## Docs available (file_read to open)'
catalog — top-N docs by recency as 'path — descriptor', hard-capped at
DOCS_CATALOG_MAX. One line each, so it stays present without the
poisoning the docs gate suppressed. Source layout still excludes doc
content for non-doc prompts.
Bounded LLM "are you sure?" pass over the capability gaps part 1 detects, run
once at plan-lock before the operator is asked to approve — honest mistakes
self-correct without escalation; only a genuine tool need reaches the human.
- CapabilityGapReflector: fun-interface seam in core:kernel (plain-data in/out,
no infrastructure:workflow dep), mirroring SemanticReviewer/SalvageJudge.
- CapabilityGapReflectorImpl (apps/server): one InferenceRouter call for the
whole gap batch, no per-gap loop, no retry; runCatching degrades to a safe
RESOLVED-advisory default on any failure (unroutable/timeout/malformed JSON) —
a broken pass can never manufacture a NEEDS_TOOL escalation or a grant.
- CapabilityGapReflectedEvent(verdict RESOLVED|NEEDS_TOOL) recorded per gap and
registered in eventModule; replay reads the event, never re-invokes inference
(invariants #7/#8/#9).
- FreestyleDriver.lockAndRun: RESOLVED is advisory (recorded, plan untouched —
invariant #3); NEEDS_TOOL is appended to the existing requestPlanApproval
preview so the operator decides — no auto-grant anywhere (#4/#5).
- reflector nullable -> degrades to part-1 behavior when unwired.
Verified: ./gradlew :core:events:test :core:kernel:test :infrastructure:workflow:test :apps:server:test green.
Bundles three operator-reliability guardrails (Vikunja #28/#29/#30) plus the
in-flight branch WIP they were built on top of (reasoning_content capture,
operator/project profile editor, write-jail workspaceRoot fix) — the tree is
interdependent (SessionOrchestrator references reasoningArtifactId from the WIP)
and does not compile as separable subsets, so it lands as one commit.
Guardrails:
- #28 mid-stage steering: ClientMessage.SteerSession -> GlobalStreamHandler ->
orchestrator.submitSteering, reusing SteeringNoteAddedEvent + existing context
fold (advisory, non-authoritative; invariants #3/#7). Closes the gap where
steering typed off an approval gate was silently dropped.
- #29 shell-in-file guardrail: ShellInFileContentRule (core:toolintent) blocks a
file_write whose content is a bare shell command (e.g. "mkdir -p ..."); FileWriteTool
description now advertises auto-mkdir of parent dirs. Basename-allowlist so the
extensionless case is caught; scripts/Makefiles/multiline exempt.
- #30 pt1 capability-gap detector: deterministic CapabilityGapDetector maps stage
intent -> implied ToolCapability, compares to granted tools, emits advisory
CapabilityGapDetectedEvent in FreestyleDriver.lockAndRun. Recorded, never fails
the gate and never auto-grants (invariants #3/#4/#5). Reflection rung is pt2.
Verified: ./gradlew check green (whole tree).
Retry-agency invariant: a stage may only retry a gate it has the capability
to change. A write-less stage failing a build/contract/static gate (e.g.
freestyle final_verification with allowedTools=[shell]) can never fix it, so
retrying in place is futile until the budget drains (Vikunja #41).
Instead: open a FailureTicketOpenedEvent (category + requiredCapability derived
deterministically from the gate id, no LLM) and route to a recovery stage that
holds the capability, bounded by a small per-stage route budget.
- Slice 2: SalvageDecision.RECOVER (ternary CONTINUE/RECOVER/FAIL) lets the
review-gate salvage judge hand off to recovery. Shared routeToRecovery()
unifies the deterministic agency guard and the judge on one destination;
decideGateExhaustion now returns StepResult?.
- Return-to-sender: recovery's exit is dynamic (recoveryReturnMove) — it goes
back to the exact ticket-origin stage to re-run its gate, so a write-less
gate anywhere in the graph is handled without skipping intervening stages.
The synthesized recovery->terminal edge is now only a no-ticket fallback.
- Freestyle wiring: ExecutionPlanCompiler injectRecovery flag (Main passes
true) synthesizes a write-capable recovery stage; ticket evidence reaches it
via buildRecoveryTicketEntry.
- Read-only tools always present: StageConfig.effectiveAllowedTools adds
file_read/list_dir to any tool-granting stage (fixes the verifier reaching
for `shell ls -R` to inspect the tree).
Tests: RecoveryRoutingTest (deterministic gate, no static return edge — proves
dynamic return) + GateRetryBudgetExhaustionTest RECOVER case + two compiler
tests. All green; detekt clean.
Replaces the single shared per-stage retryCount (reset on TransitionExecuted,
shared across all post-stage gates) with a per-gate budget. Motivated by run
2e468f9f, where a promising freestyle run was terminally FAILED because the
contract gate burned all 3 shared retries on one trivial miss before the
semantic-review gate ever ran.
- StageExecutionResult.Failure gains a `gate` id; each gate tags its failures.
- OrchestrationState gains gateRetryBudgets / gateFailureFingerprints /
gateSalvageUsed (all rebuilt from events, reset per-stage on TransitionExecuted).
- FailureFingerprint normalizes+hashes the failure reason; RetryCoordinator.decide
charges a gate's budget only when the fingerprint is unchanged (no progress),
so a moving run is never penalised. Returns Retry | Exhausted.
- Hybrid exhaustion: deterministic gates fail; the review gate consults a
SalvageJudge (LLM, or a deterministic allow-one-reset fallback), recorded as
RetrySalvageDecidedEvent (invariant #9). CONTINUE resets the gate budget once;
a second exhaustion is terminal.
- Review gate is now the sole authority on review-retry termination; the old
REVIEW_BLOCK_RETRY_CAP is repurposed as a high absolute backstop only.
- ServerModule escaped-exception path now records a truthful terminal
WorkflowFailed (real stage/reason/retryExhausted) via recordUnhandledFailure.
Tests: DefaultRetryCoordinatorTest (fingerprint charging) +
GateRetryBudgetExhaustionTest (deterministic exhaust / review CONTINUE-then-
terminal / review FAIL / null-judge fallback) + reducer coverage.
Plan-compile gate (#19): PlanCompilationCheck seam (null-on-replay),
runPlanCompileGate guards a produced execution_plan slot and compiles its
cached content via ExecutionPlanCompiler, emitting PlanCompileCheckedEvent.
On failure the architect gets a retryable hand-back and self-corrects;
exhaustion terminates the dead-end workflow instead of shipping an
uncompilable plan.
Semantic-review gate (#20): SemanticReviewer seam + StageConfig.semanticReview
opt-in (TOML semantic_review + freestyle plan JSON). runReviewGate reads the
FileWritten manifest (never blind context), asks a review-capable model for
PR-comment findings, and is advisory — blocks retryably only on FAIL plus a
correctness finding >=0.7 confidence, capped at 2 blocks so a stubborn stage
completes advisory-only rather than trapping. SemanticReviewerImpl talks to
the provider directly; any reviewer error degrades to PASS. REVIEW_MAX_TOKENS
is 8192: gemma is a reasoning model and 1024 truncated it mid-reasoning before
it reached the JSON verdict (empty content -> parse degraded to PASS).
Both gates live-QA'd on the real repo: plan-compile passed on a freestyle
web-UI scaffold; semantic review caught all 3 planted bugs in a maxOf() and
exercised the block->retry->cap safety valve end-to-end.
Gate 2 (contract) and Gate 4 (execution) of the 4-gate staged-verification
design, plus the two gate-quality fixes found in live QA.
- Gate 2: KindContractTable (kind→assertions registry, universal floor,
additive project overrides) + KindInference (path→kind, pure/replay-safe)
+ ContractAssertion model; ContractGateEvaluatedEvent (registered);
ContractAssertionEvaluator seam + FileSystemContractEvaluator (FS/TEXT,
COMPILER skipped); runContractGate in runPostStageGates — a stage that
produces file_written artifacts must have every declared+written file
exist/non-empty/parse, else retryable hand-back with per-assertion feedback.
- Option A: ExecutionPlanCompiler puts concrete (non-glob) plan `writes` into
StageConfig.expectedFiles, so a declared-but-unwritten file fails file_exists.
- Gate 4: BuildExpectation enum (none|module|project|tests) + plan field +
closed-set compiler validation; runExecutionGate resolves the alias against
the bound project profile commands and runs it as a deterministic gate.
- Live-QA fixes: react_entry kind so main.tsx/index.tsx aren't required to
export a default component (was an unwinnable false-positive); JSONC
tolerance (allowComments/allowTrailingComma) so tsconfig.json passes valid_json.
Seams are null on the replay harness (no-op) — recorded events are truth (#9).
The 'router' name was misleading — it's the always-on conversational front-end
(CHAT triage + STEERING into a running workflow), not a routing layer, and it's
distinct from InferenceRouter. Rename core:router -> core:talkie, package
com.correx.core.router -> com.correx.core.talkie, and RouterFacade/Config/State/
Repository/ContextBuilder/Projector/Reducer/Response -> Talkie*. Config section
[router] -> [talkie] (legacy [router] still read as fallback).
Persisted wire formats are preserved: ChatTurnRole.ROUTER and the
RouterNarrationEvent @SerialName("RouterNarration") stay, so existing event
logs still replay. RouterNarrationEvent the class is now TalkieNarrationEvent.
RepoMapComputed recorded per session (in-memory scan cache keeps the walk-once
guarantee); zero-score embedder hits filtered before reaching the agent, falling
back to the deterministic repo map; REFERENCE_EXISTS surfaces a closest-path hint
via closestPathByFilename. Breaks the hallucinated-package-path read loop even
with a noop embedder.
Wrap the per-event mapper.map in runCatching in the replay loop so a single
event the mapper can't handle no longer kills the whole WebSocket stream.
Defense-in-depth beyond the AnyMapSerializer fix.
- clarDismissed was model-global but only reset when the clarification's
session was selected on arrival, so a clarification for an unselected
session stayed silently hidden. Reset on every arrival.
- input bar (in-session + launcher) only truncated lines, never padded to
width, so the terminal backdrop bled through the right. Pad with padTo.
- action/narration/user rows prefixed plain (unstyled) spacers around their
icons, leaving transparent gaps near the symbols. Use bg-styled spacers.
Approval-card and preview JSON artifacts (the freestyle execution_plan, the analyst's analysis) rendered as a raw JSON dump. Add a JSON-aware preview: a scannable goal + numbered stage list for execution_plan, indented key/value lines for other objects, with light highlighting. Non-JSON previews fall back to the raw line view unchanged.
The main render path never applied the Screen backdrop, so any sub-view that left a line short or a row empty showed the transparent terminal background. Pad every frame to full width×height with the theme backdrop before display; content stays top-left anchored so caret coords are unaffected.
The /events limit test still asserted the oldest event (seq 1) after 18cbd34 deliberately switched the no-fromSeq path to return the tail (so a pending approval at the tail stays visible to a headless operator). Expect the tail (seq 3) and add a post-filter tail assertion (seq 2) so the test actually verifies truncate-after-filter.
Move embedder construction ahead of the engines so the context pack builder ranks
freeform turns by query relevance (query-conditioned selection). Default
compression_level 4 (format + static cache + token pruning + age-tiering) for a 12b
on a 16k window.
Three defects surfaced by a live headless freestyle_planning run (all made a
long execution workflow fail or stall in ways invisible to a REST operator):
1. retryCount was session-global (DefaultOrchestrationReducer): TransitionExecuted
updated currentStageId but never reset retryCount, while shouldRetry gates on
it per-stage. An early stage that burned its 3 retries starved every later
stage of its own — the next stage's first *retryable* failure went terminal.
Reset retryCount on stage entry; back-edge loops stay bounded by the separate
refinementIterations counter. Regression test added.
2. Freestyle stages ran at StageConfig's 4096-token default (ExecutionPlanCompiler
never set a budget) vs 16384-32768 for static role_pipeline stages. A tool-heavy
stage truncated its context every round, evicting the file_read results it just
gathered, so it re-read forever and never accumulated enough to write. Set 16384.
3. GET /events returned the OLDEST `limit` events (readFrom(0) then take): for a
session past `limit` events the tail — including a pending ApprovalRequested —
was invisible to a headless/REST poller, the exact caller POST /approve serves.
Default now tails; explicit fromSeq still paginates forward.
Stage approvals were WS-only (ClientMessage.ApprovalResponse), so a headless
run had no way to clear an approval gate — and apps/cli ApproveCommand already
POSTs to this path (it 404'd). The route is keyed by session: a session
suspends on at most one approval at a time, so ApprovalCoordinator resolves the
pending requestId server-side (new pendingRequestFor reverse lookup). Decision
maps approve/steer->APPROVE, reject->REJECT; routes through the same
ApprovalCoordinator.handleResponse the WS path uses.
buildToolConfig built FileReadConfig without workingDir, unlike the sibling
fileWrite/fileEdit configs (and buildToolConfigForWorkspace), so the default
tool registry's file_read resolved relative paths against the JVM process cwd
instead of the configured workspace. When the server is launched from outside
the workspace (e.g. `./gradlew :apps:server:run`, whose cwd is apps/server),
a `file_read .` from a curl-started session resolved to the launch dir, which
is not in the allowed paths, and was rejected with "Path '.' is not in the
allowed list" — while it worked on machines where the launch cwd happens to
coincide with an allowed path. Pass workingDir so relative paths anchor to the
workspace, matching the other file tools.
