Reviewer's GuideThis PR introduces a Docker Compose-backed durable bandit trainer that uses immutable image identities and job-scoped hardened containers, while reusing the existing transactional reservation, staged receipt, recovery, cancellation, settlement, and promotion flow; it also adds real Docker integration drills, documentation, PM evidence, and release coverage updates.

Recursive programmes can now select
adapter.kind: "compose-bandit"with a local immutable image ID through the durable process controller. Each generation uses the existing content-bound job, approved resource reservation, staged receipt validation, settlement and promotion checks.The controller generates a job-scoped, networkless Compose project with only job artifacts mounted, no host ports, a read-only root filesystem, dropped capabilities and the invoking numeric UID/GID. Cleanup resolves the exact named and labelled container and removes its immutable daemon ID. Recovery adopts valid staged completion without retraining or retains incomplete staging with a terminal outcome.
Cleanup errors previously replaced trainer errors in
finally, misclassifying cancellation and rejecting successful runs. Launch and recovery now reportcleanup: { code: "cleanup_failed", error }separately in the durable job body and transition history. A valid completion stays materialized, cancellation retainsprocess_cancelled, and trainer failure retains its original error. Diagnostic text is bounded to 4,096 characters and replaces the staging directory with<staging>. Cleanup failures can still leave job resources requiring inspection.Fifteen tests use real Docker Compose and real temporary SDK trackers. The four cleanup regressions run real container launch/training/kill/removal and inject only the
compose downfailure through the executable boundary; no SDK mocks. They cover cancellation, success, trainer failure and recovery of completed staging. Existing drills cover launch/replay, contention, crash windows, independent tracker isolation, missing receipts and two changed promoted generations.Behavioural revert proof: restoring only the throwing cleanup in
launchComposeTrainerfails all three primary-outcome regressions (0/3 pass); separately restoring the recovery cleanup behavior fails its regression (0/1 pass). Fixed code passes 4/4 through the linkedpm testsnapshot run. Original Compose feature reverts remain recorded on the PM item.Validation:
npm run release:checkandbun run release:checkeach pass 582/582 tests, zero failures/skips/cancellations/todo, exact 100/100/100/100 statement/line/branch/function coverage across 28 sources, 266 documented declarations, zero duplication and zero production audit findings. Identity, release attestation, packaging and changelog checks pass under isolated CI Git/home settings. All thresholds, dependency pins and CLI deadlines are unchanged. The packed LM CLI measured 12.623 seconds (npm) and 12.272 seconds (Bun), within its unchanged 20-second bound.PM result tracking is disabled by project policy; tracker comments preserve the gate and revert results. Kernel CPU/storage enforcement and existing packed LM CLI timing variability remain separate follow-ups. Items remain open for orchestrator verification.

Summary by cubic
Adds Docker Compose execution for durable process trainers so recursive programmes can select a container trainer through the same controller that runs local process trainers, using the same reservation, receipt, and cancellation contract. Kernel-enforced CPU and storage quotas remain a separate follow-up.
