Both defects come from live session fced377e, where scaffold_frontend burned 89
turns without converging.
#419 — the stage output manifest never tracked deletions. A deletion is a
FileWrittenEvent with a null postImageHash, and stageWrittenPaths filtered that
per-event instead of per-path, so a written-then-deleted file stayed in the
manifest forever. The contract gate stamps file_exists on every entry, which made
deleting — and therefore renaming, which is delete plus write — a permanent
contract violation. That deadlocked against the build gate: it ordered "rename it
to use the '.cjs' file extension", the agent complied, and the contract gate then
failed file_exists on the .js it had just been told to remove. Keep the last
mutation per path instead. Fixed in the shared function, so the build-gate
toolchain probe, the review gate, and verification all stop seeing deleted files
too. Moved to its own file to keep the gates file under the detekt function cap.
#417 — file_edit failed 4 of 6 live calls, all "Target not found" with a correct
"did you mean" suggestion attached. flexibleMatch already tolerated indentation
drift but walked target lines against file lines positionally, so one blank line
the model dropped shifted every later index and missed the whole block. Compare
only non-blank lines and map the hit back to real file lines. Ambiguity still
fails rather than picking a match, and reindent keeps handling the writeback.
Guard tests both ways, each mutation-verified against the old logic.

A foreground long-running command (npm run dev, vite, a --watch task) hit
the 30s timeout and returned recoverable=false, giving the stage no
transition to take -> WorkflowFailed "no transition condition matched"
(killed session d734e1de). A non-zero exit right below already returns
recoverable=true; a timeout is no more fatal. Return recoverable and coach
the model to start the process detached (nohup ... &) and verify separately,
or run a one-shot that exits. No background-process registry: the model
backgrounds it itself via `&`, which already routes through `sh -c`.

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.
A stage (configure_ethos_theme) looped forever re-writing an identical
postcss.config.js: file_write returned "written successfully" on a byte-
identical write, and the retry-feedback entry that says WHY it failed got
truncated out of context every turn, so the model cold-started on the same
wrong idea. CAS hashes leaked into its face from two sides too.
- SandboxedToolExecutor: a write whose result is byte-identical to disk now
returns "No change: … nothing was written" (+ noop=true) instead of a false
success signal. Uses the pre-image hashes already captured for reversibility.
- DefaultContextPackBuilder: pin "retryFeedback" in neverDropSourceTypes so the
failure reason + already-written-files list survives truncation.
- ContextFeedback: drop the opaque "— CAS <hash>" from the retry entry; path only.
- tool_output withheld until the session actually spills over-cap output to CAS
(StageConfig.ALWAYS_AVAILABLE_READ_TOOLS -> on-demand via sessionHasSpilledOutput),
so a hash-eating tool isn't advertised to every stage that never spills.
- Wrap 10 long lines in kernel to bring detekt back under maxIssues (99 -> 89).
Tests: infrastructure:tools (+2 no-op cases), core:{transitions,context,kernel} green.

file_edit failed en masse for small models on two ergonomics traps:
- replace() rejected calls that sent `content` (the append param) instead of
`replacement` — intent unambiguous; now accepted as an alias.
- exact-string match died on leading-whitespace drift (model can't reproduce
indentation). Added whitespace-flexible line matching + replacement reindent,
wired into both the pre-exec validation gate and replace().
Also made the WRITE_SCOPE / PATH_OUTSIDE_MANIFEST block messages emit a literal
copy-pasteable task_update(id=..., affected_paths=[...]) call and warn against
action=block — the exact wrong turn models kept taking (18x in one session).

Weak models re-emit `npm -v` as ["npm,","-v"] or ["npm\",","\"-v\""] —
the JSON array separators leak into the tokens. The collapsed-array guard
rejected these, and the model re-emitted the identical mangle until
stage_loop_break killed the run (observed 6x on the web-ui QA workflow,
session 508c8d58). Strip stray leading/trailing quote/comma per token so
the call runs instead of looping the stage to death. Internal commas
(--foo=a,b) are kept; a single fully-collapsed token still rejects.
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
Diagnosed from session 508c8d58 (frontend freestyle run, WorkflowFailed):
three independent weak-model-hostile gates, none a model-capability problem.
- shell: split a collapsed single-string command line (["npm create vite …"])
into tokens instead of rejecting it as a "collapsed array". The model
reliably re-emits this shape; rejecting looped bootstrap_frontend until
stage_loop_break. JSON-escape mangles (quotes/commas in argv[0]) stay rejected.
- recovery: a stage_loop_break route now gets a "Stuck-loop ticket", not the
"Contract arbitration ticket". The arbitration prompt told the model to read
and reconcile "the files named below" — but a tool-syntax loop names zero
files, sending the recovery agent grepping the repo for 40+ turns until the
repair ladder exhausted.
- plan lint: H3 (unreferenced_prompt_artifact) demoted from hard failure to
soft finding, and seeds excluded from it. It word-matches artifact IDs in
free prose and cannot tell a forgotten dep from a descriptive mention, so as
a hard gate it burned architect retries on words it couldn't reword away
(analysis/dod). Hard tier is now deterministic graph facts only (H1/H2).
Tests: ShellToolTest, PlanLinterTest, RecoveryRoutingTest green; detekt clean.

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.

A full file_write that shrinks a non-trivial existing file (>=30 non-blank
lines) by >60% into a stub with literal `...` placeholders is almost always
the model rewriting a file from memory instead of editing it — the incident
that silently broke SessionRoutes.kt (273->28 lines) in run f11afb08. Reject it
(recoverable) and steer to file_edit. Requires BOTH the hard shrink AND elision
markers, so dead-code refactors and new-file scaffolds pass untouched. Runs
before the write regardless of approval tier, so the auto-driver can't wave it
through.

HeadTail now accepts an optional salience regex + cap: middle lines matching
it (error|fail|exception|panic|traceback|✗, case-insensitive) survive
truncation in place instead of being silently dropped, so a decisive error
buried in the middle of a long build/test log still reaches the model-facing
context entry. ShellTool's outputCompressor spec wires this in; the raw
build-gate receipt path is untouched.

ChildProcess defaults stdin to /dev/null (scaffolders fail fast rather than
hang). MCP stdio is the inverse: the server reads requests from stdin and sees
EOF then exits immediately without a live pipe. spawn() now restores
Redirect.PIPE. Verified end-to-end: Correx spawns the real codebase-memory-mcp
v0.9.0 and mounts its 8 tools as mcp__codebase-memory__*.
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
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.

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.
Weak local models reached for shell find/grep -r (unjailed, dumps
.gitignore'd trees, floods context) to answer 'does frontend/ exist?' /
'where is symbol X?'. Add two jailed, gitignore-aware read-only tools:
- GlobTool (name 'glob', T1, FILE_READ+DIRECTORY_LIST): find files by
glob pattern; survey-exempt from anti-hallucination read gates like
list_dir.
- GrepTool (name 'grep', T1, FILE_READ): regex content search, returns
path:line: text; skips gitignored, binary (NUL), and >2MB files.
Both reuse GitignoreMatcher + PathJail from the filesystem package,
share FileReadTool's jail/anchor/toggle, cap at 200 results. Registered
in ToolConfig.buildTools (fileRead block) and added to
StageConfig.ALWAYS_AVAILABLE_READ_TOOLS so every tool-granting stage can
call them. 6 tests green.
Vikunja #37.
withTimeout wrapped a blocking process.waitFor() that coroutine cancellation
can't interrupt, so a hung process hung the stage until it exited on its own;
and destroyForcibly() killed only the direct child, leaving sh -c grandchildren
(the real npm/tsc) as orphans. Use process.waitFor(timeout, MILLISECONDS) for
an on-the-clock deadline, and kill via toHandle().descendants() + the parent.
An operator argv runs via `sh -c`, so ["ls","&&","rm","-rf","/"] passed an
argv[0]-only allowlist check with {ls} then executed rm. Now every command
position (argv[0] + the token after each &&/||/|/;/& separator) must be
allowlisted; shell builtins are implicit, redirect targets are treated as
filenames. Tests for the bypass, an all-allowed chain, and a redirect target.
Backups were named workingDir/${fileName}.bak — two affected paths with the
same filename in different dirs overwrote each other's backup, so failure
restore wrote the wrong content. Name by full-path hash. Latent today
(single-path tools) but a correctness landmine for any multi-path tool.
The 'Not a directory' branch returned a bare message; models re-issued the
identical list_dir until cancel (session a60c54b0). Name the remedy: the path
is a FILE — file_read it or delete/convert it first. Regression test added.
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.
On a real (large) codebase, a file_read of a big file dumped the whole
body into L2 uncapped, evicting the files the stage actually needed —
the ContextTruncated we saw on real-repo runs. Bound it:
- readFile: auto-truncate a read-to-EOF past MAX_READ_LINES (400) with a
note pointing at start_line/end_line; hard char backstop (20k) for
very long lines. An explicit end_line is deliberate paging, honoured
in full. No contentHash baseline on a truncated view, so the
stale-write gate forces a real read before an edit.
- listDir (single-level): cap at LIST_MAX_ENTRIES (400) with a note.
(ListDirTool's recursive walk was already capped.)
Greenfield discovery/analyst stages thrashed on plane-2 REFERENCE_EXISTS
rejections: the model listed a not-yet-created dir (e.g. frontend/), got
hard-BLOCKED every round, and burned MAX_TOOL_ROUNDS without progress.
- New ToolCapability.DIRECTORY_LIST; ListDirTool declares it alongside
FILE_READ. ReferenceExistsRule now exempts directory enumeration (a
listing of an absent dir truthfully reports empty; only hallucinated
file *reads* still fail loud). Dispatch stays on capability, not name.
- Stage-agnostic rejection-loop breaker in the tool loop: after 3 rounds
where every tool call is rejected (BLOCKED/ERROR) with no success,
force the model to produce its output. Covers JSON-emitting stages the
read-loop breaker (file_written-only) never protected.
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).
Three tool-path correctness fixes:
- Tool-execution events were emitted twice — SandboxedToolExecutor and
SessionOrchestrator.recordToolExecution both emitted Completed/Failed/
FileWritten per call (double TUI rows, double-counted metrics). Split
ownership: orchestrator is the sole recorder of Completed/Failed (truncates
output, drives the read-before-write gate); executor owns Started +
FileWritten (pre/post-image hashes it alone can capture).
- computeToolPreview still gated on operation == "write", but file_write lost
its operation param when delete was split out, so it bailed to raw-args for
every write (approval card showed raw JSON). Drop the dead guard.
- A file_read blocked by REFERENCE_EXISTS can never complete, so it could never
lift read-only mode: a stage writing a NEW file deadlocked (writes filtered,
every read of the not-yet-created target blocked) until MAX_TOOL_ROUNDS.
Lift read-only on a REFERENCE_EXISTS block, and reword the block message to
tell the model to file_write directly. Regression test added.
Writing to an existing directory path threw an IOException marked recoverable=false, which the orchestrator turns into a FATAL non-retryable stage failure — dead-ending the workflow on a correctable model mistake. Guard the directory case up front with a clear message and make write IO errors recoverable so the retry-with-feedback loop can self-correct.
Uncommitted work from the session-robustness-and-dox branch sweep
(docs/qa/QA-session-robustness-and-dox.md), verified alongside the
compression/context fixes:
- SandboxedToolExecutor: validate tool args centrally before dispatch. A
malformed/missing-arg call becomes a recoverable ERROR: (surfaced with the
tool's arg schema so the model can correct + retry) instead of stranding
the stage with no artifact. + validation test.
- PlanLinter: seed artifacts (analysis) produced by the planning phase count
as available producers, so a plan stage that `needs` them isn't flagged as
an unproduced-need; H1 unproduced-needs + trap-state checks. + tests.
- DefaultSessionOrchestrator: live-QA robustness fixes (event-tail /
per-stage budget + retry handling).
- workflow prompts/configs: DOX AGENTS.md alignment + freestyle/task/role
prompt tweaks.
- SessionOrchestratorIntegrationTest: coverage for the above.
- FreestylePlanningWorkflowTest: allow list_dir in analyst tools (follows the
list_dir wiring in 968cbfa).
- QA plan doc for the branch sweep.
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.
Enable autonomous QA through a remote OpenAI-compatible provider (NVIDIA NIM)
and harden the tool/approval path so unattended multi-stage runs complete.
- inference: add openai_compat provider (Bearer chat-completions for NIM/OpenAI),
dispatched by provider type "nim"/"openai"; key via api_key/api_key_env.
- server: bind configured [server] host/port instead of a hardcoded 8080;
POST /sessions accepts an optional `intent` (WS parity) for intent-driven workflows.
- kernel: thread the bound operator profile's approval_mode into per-tool gating so
auto/yolo enable unattended approval (engine still consulted; policy/plane-2 BLOCK
stays terminal); on a recoverable tool failure feed the tool's arg-schema back into
context so the model self-corrects instead of repeating a malformed call.
- tools: split deletion out of file_write into a separate, explicitly-named file_delete
tool — a model can no longer delete a file by getting a write-mode parameter wrong.
- server: add GET /metrics/tool-reliability — per-model tool-call validity from the
event log (measurement groundwork for capability-aware routing).
- docs: update AGENTS.md across kernel, tools, server, inference.

When a write is blocked for being outside the claimed task's
affected_paths, the implementer can propose widening scope via a new
T2 propose_scope tool. The operator decides (invariant #4 — the agent
can't self-grant). Approve unions the proposed paths into the task's
affected_paths (existing TaskAffectedPathsSetEvent); activeScope
re-derives the wider manifest from events so the same write then passes.
Reject blocks the task (via TaskClaimCoordinator.blockActiveTask, hooked
on both approval-denial branches, scoped to propose_scope) so the loop
advances. No new event types.
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.
The freestyle analyst can now break a large goal with dependency seams or
independent review/handoff points into a parent epic + DEPENDS_ON-linked children
in a single T2 approval, instead of N separate task_create calls. Parent
DEPENDS_ON every child (completes last); each child IMPLEMENTS parent. Resolves
depends_on by ref or index; rejects cycles, unresolved refs, missing title/goal,
and empty batches; same batch dedup + force_reason convention as task_create.
A session works one active task, so multi-task work is multi-session by
construction: the analyst names the single ready task this run works, the architect
threads only that one, and siblings are claimed by later runs via task_ready
(claim-driven; no scheduler, /tasks/next stays rejected).
Doctrine: analyst_freestyle.md picks one-task-vs-decompose and names the ready
task; architect_freestyle.md threads only that one; plus the L0 policy line.
freestyle_planning.toml analyst gains task_decompose (pinned by
FreestylePlanningWorkflowTest).

Bypassing a gate with force=true now requires a force_reason, recorded as a
"[force] ..." note on the task so the override is auditable (visible in history
and the context bundle) rather than a silent escape hatch. Applies to the agent
tools: task_create (dedup override) and task_update (claim over unmet blockers,
complete with no in-scope writes). force without a reason is rejected.
The REST POST /tasks create override (operator/CLI path) still takes a bare force
and is left for a separate call.

Block writing a file whose on-disk content changed since the session read it — a
concurrent/external edit the agent's view doesn't reflect. file_read records a
content hash on whole-file reads; the orchestrator's completion path now carries
the tool's structuredOutput (it previously dropped it, unlike SandboxedToolExecutor
— the two paths were inconsistent), so SessionContext.readHashes folds it.
StaleWriteRule compares the current hash (WorldProbe.contentHash) against the
read-time hash and BLOCKs a mismatch, telling the agent to re-read first. Files the
session wrote itself are excluded, so its own edits never look stale; partial reads
set no baseline.

Completing a task that declared affected_paths but saw no matching write this
session is now blocked ("marked done without doing it"), escapable with force.
TaskUpdateTool reads the session's writes through a SessionWrites port whose
adapter folds SessionContext (writes = recorded receipt.affectedEntities), and
matches them against the task's affected_paths globs.
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
Claiming a task now emits SessionWorkingTaskEvent{taskId, affectedPaths} into the
session's own stream (via a SessionFactRecorder port + event-store adapter), and
SessionContextProjection folds it into SessionContext.activeTask. So a gate learns
"which task is this session working, and its scope" by reading the session stream
— no cross-stream scan, no kernel->tasks dependency. Re-emitted on an affected_paths
edit by the claimant, so the snapshot scope stays current; latest wins on replay.
This is the data source the write-scope gate needs (next).

Harden the claim warning into a block: task_update action=claim on a task with
unmet blockers is now rejected (no mutation) with the blocker list, instead of
claiming-with-a-warning. Escapable with force=true, which claims anyway and keeps
the "claimed despite unmet blockers" warning for the audit trail.

The doctrine says "search before creating", but that leans on the LLM; this is
the backstop against an agent re-creating a task across runs. TaskService.
findDuplicates matches active (non-terminal) same-title tasks, case- and
whitespace-insensitively — a DONE/CANCELLED look-alike is not a duplicate, since
that work may legitimately recur.
- task_create rejects a duplicate, naming the look-alike and offering force=true.
- POST /tasks → 409 with the duplicates, or force:true to override;
correx task create --force.

Bring the work graph into the agent loop:
- task_ready (T1): lists tasks ready to work now (TODO, all dependencies
satisfied) so an agent looking for work can pick one and claim it. Surfaces
work; never assigns (honouring the rejected /tasks/next). Registered in
TaskTools — left unwired in the request-driven example workflows, where it
would be noise; it belongs in an autonomous work-pull workflow.
- claim guard: task_update action=claim appends a WARNING naming any unmet
blockers, so an agent knows when it has jumped a dependency. Surfaced, not
hard-blocked — status is derived, so we don't fight the reducer.

The task tools were registered but had only mechanical descriptions and no
standing policy, so agents knew the tools existed but not when to reach for
them. Lead each of the five descriptions with its trigger (when to use, when
not to) and add a task-tracking convention to .correx/project.toml, which is
rendered into every stage's L0 context.

Ranked exact/substring search: TaskSearch (all terms AND, ranked title >
key > goal > criteria > notes) over one project or the whole board via
TaskService.search. Surfaced as GET /tasks?q=, a read-only task_search tool
for agents, and a `/` filter in the TUI board.

When an agent creates or claims a task via the tool, record its session as
a CONTEXT/SESSION link so the context bundle's session resolver has real
edges to inline (status/intent/workflow). Shared linkOriginSession helper;
reducer dedupes so create+claim from one session is a single edge. The REST
create path stays unlinked (no agent session there).

The context bundle resolved only TASK and DOC link targets; ARTIFACT and
SESSION stayed raw. Add two ports (TaskArtifactResolver/TaskSessionResolver)
with apps/server adapters: artifacts resolve to producing stage/session +
content excerpt from CAS, sessions to status/intent/workflow. Unresolved
targets still fall back to raw links. Wired through the tool and REST bundle.
