M13-03F Status

status: done task: sandbox resource disposal gate updated: 2026-08-19 America/New_York enablingTask: false parityStateChange: false

Scope

The sandbox Worker now owns an explicit disposal receipt. Both MessagePort endpoints, the timer, AbortController, transferable buffer, pending request and cache reference are observed before disposal and are all zero after the first dispose. A second dispose is accepted and reports idempotent=true; the cleared timer produces no late message. Script execution remains DISABLED, and this task does not claim same-session recovery or server isolation.

Next Task

M13-03G: recover a small script in the same session with a new Worker generation while keeping the Main revision/source hash stable and extending the audit hash chain.

Rollback

Remove the dispose protocol, Worker, focused tests/checker, report, manifest, package command and this status entry; restore M13-03E as the queue tail and move nextTask back to M13-03F.
