Delete branch "feature/m6-async-infra"
Deleting a branch is permanent. Although the deleted branch may continue to exist for a short time before it actually gets removed, it CANNOT be undone in most cases. Continue?
Summary
Add async command execution infrastructure allowing plan phases (Execute, Apply)
to run as background jobs processed by a thread pool of workers, per ADR-002 and
issue #312.
When
async.enabledisTrue, plan phase transitions enqueue jobs instead ofexecuting synchronously. An
AsyncWorkerservice polls for queued jobs anddispatches them to a
ThreadPoolExecutorfor concurrent execution withconfigurable concurrency, graceful shutdown, stuck job detection, cancellation
token propagation, and job cleanup.
Changes
Domain Model (
async_job.py)AsyncJobPydantic v2 model with ULID primary key, status state machine(
queued → running → succeeded/failed/cancelled),worker_id,last_heartbeat,error_message(audit trail for failed jobs), andpayload_jsonwith schema versioning for forward compatibility.AsyncJobStatusenum withVALID_JOB_TRANSITIONSmap enforcing legalstate transitions via
InvalidJobTransitionError.serialize_job_payload/deserialize_job_payloadhelpers with inputvalidation.
Application Service (
async_worker.py)AsyncWorkerwithThreadPoolExecutor-backed concurrent job execution(configurable via
async.max_workers).cancel_jobonly signals thecancellation token for running jobs;
pickup_and_execute(the owningworker thread) performs all state transitions.
WorkerHealthReportwithjobs_processed,jobs_failed,jobs_cancelledcounters and UTC heartbeat.InMemoryJobStorewith atomicsnapshot_counts()(single-lock queuedepth) and
remove_expired()(single-pass cleanup).detect_stuck_jobs()marks timed-out jobs as failed with descriptiveerror_message.Infrastructure

Thanks for the async infra buildout and the thorough test coverage. I found several blocking issues that need to be addressed before merge.

src/cleveragents/application/services/plan_lifecycle_service.py(or related plan execute/apply paths) to enqueue jobs whenasync.enabledis true, so the feature as described in the PR does not take effect. Please integrate job creation/dispatch into the plan execute/apply flow or narrow the PR scope and description accordingly.docs/specification.mdexplicitly states “No Plan Queuing,” but this PR introduces queued async execution. The reconciliation note indocs/reference/async_architecture.mdis not sufficient per CONTRIBUTING’s “specification-first” rule. Please update the specification (and/or add an ADR) to legitimize queuing, or align the implementation to the current spec.agents project context inspect/simulatenow raiseNotImplementedError, and ACMS config options were removed fromcontext set/show. This contradicts the spec and removes existing functionality/tests (src/cleveragents/cli/commands/project_context.py,docs/reference/project_context_cli.md, removedfeatures/context_cli_wiring.featureandfeatures/steps/context_cli_wiring_steps.py). Please restore the previous behavior or update the specification and provide equivalent behavior/tests.CHANGELOG.mddescribing the async subsystem and any behavior changes.error_messagepersists raw exception text; consider redacting withshared/redaction.pybefore storing/logging (src/cleveragents/application/services/async_worker.py).Given the P1 items, I’m marking this as request changes. Happy to re-review once these are addressed.
