Queue worker results before settlement cleanup, claim terminal and death boundaries before provider callbacks, and close late-message admission.
Make child cancellation and disposal reentrancy-safe across the workflow bridge and generic subagent wrapper, with adversarial regression coverage and RFC documentation.
Make Cordis construction and teardown ownership reentrancy-safe, then carry caller and provider ownership through reservation, setup, publication, quiescence, and sentinel retirement.
Stabilize registry carriers and factory/workflow boundaries, add adversarial lifecycle regressions, and align the rewritten RFC plus generated contracts with the enforced behavior.
The documented vm escape reaches process, and the worker inherited the
harness's env - so a buggy or prompt-injected script could read and
exfiltrate ambient credentials (DEEPSEEK_API_KEY et al.) without
touching a single file (ds-review-bot finding on #233).
Spawn with env: {} and a hermetic execArgv on both runtime shapes, the
same stance as dsh-code-runtime-worker and stronger than the scrubbed
env the defensive-patterns rule requires for spawned commands (a shell
needs PATH; this worker needs nothing). Ambient-channel hardening only:
an escapee keeps the process-wide privileges the trust premise already
admits - the genuine sandbox remains an engine swap.
agent-end was worker-authored only, so a start already forwarded to
observers lost its paired end whenever the worker could no longer speak
- the grace force-settle terminating a wedged script, or an unexpected
worker death - stranding progress consumers with agents that never
finish (ds-review-bot finding on #233).
The host now keeps a ledger of forwarded starts and funnels every
agent-end through one gate: worker-reported ends pair (and clear) their
entry, and both termination paths drain the remainder as synthesized
'cancelled' ends BEFORE the run settles, so ends always precede
workflow/end. A real settlement racing the force-settle loses to the
synthesized cancellation - the same first-wins override onResult applies
to the run's own result.
Pure mechanical rename now that the package's internals are the
worker-thread engine: directory, package name, spec/e2e filenames,
module tags and logger prefixes, tsconfig/knip/run-gates/AGENTS.md
references, example cordis.yml plugin ids, doc links; catalogs
regenerated and the lockfile refreshed.
