M13-04G Status

status: done
task: server process-tree cancellation
updated: 2026-08-19 America/New_York
enablingTask: false
parityStateChange: false

Scope

Real server jobs now run in a detached process group on POSIX and are cancelled as a tree. The cancellation path sends SIGTERM to the group, escalates to SIGKILL after the grace window, waits for the group to exit, and performs one idempotent job-directory cleanup. Windows uses taskkill /T /F. The receipt reports the actual signal path, cleanup count and orphan count. Execution remains DISABLED.

Evidence

npm --prefix web run test:server-job-cancellation passed 2/2 real-process unit tests and the checker.
Checker output: server-job-cancel-ok state=CANCELLED tree=SIGTERM_GROUP cleanup=1 orphan=0 residual=0 execution=DISABLED next=M13-04H.
git diff --check passed.
