Start tab and notification cleanup concurrently so a stalled notification
cannot prevent cancellation messages from reaching the page overlays.
Cover content completion, timeout, and cancellation across multiple tabs.
Share optional stop target parameters between browser_session and its internal
stop handler. Document exact request targeting, mutual exclusion, and default
stop retry behavior in the model-visible contract.
Add a public schema regression covering requestId, optional targets, and retry
guidance. Lifecycle execution remains unchanged.
Validation: 95 tool and stop recovery tests passed; TypeScript and formatting
checks passed. The new schema test reproduced the omission before the fix.
Route tool, overlay, archive, unload, and recovery cleanup through one lifecycle
owner and one job per request. Persist explicit stop intent before making a
session unusable; caller cancellation only ends its wait after admission.
Retain durable completion receipts independently of the current session so a
retry cannot stop another working session, even after background cleanup or
restart. Preserve failed default callers' retries across concurrent successful
waiters. Support exact request targeting and reject ambiguous stop targets.
Cover failed normal stops, queued and in-flight cancellation, concurrent entry
points, timer and disk recovery, persistence failures, anonymous starts, reused
IDs, unconfirmed replies, and completion receipt capacity accounting.
Validation: 303 plugin tests passed, including 31 stop recovery tests;
TypeScript checking, production build, and formatting passed.
Package lint was unavailable because publint is not installed in this environment.
Do not terminate a running child when its launcher cannot confirm startup.
A different client may already be using it, or publication may race the
launcher's deadline. Retain cleanup only before a Windows child resumes.
Add deterministic lifecycle regressions for reuse before timeout, delayed
publication and port mismatch. Run Windows success-path and updater tests
in a same-user WMI test host that verifies it is outside all Jobs, and keep
restricted-host rejection tests in the normal CI runner.

Capture initial tab identities when creating an Agent Window and retain them
through failed startup compensation. Retry cleanup through the production
stop handler, preserving later user tabs and keeping ownership if agent tabs
still cannot close.
Separate owned starting and cleanup resources from active sessions. Publish
sessions only after initialization and claim succeed, preserve the working
current session on failure, and reject ordinary operations and captures for
resources awaiting cleanup. Recheck queued operations before execution.
Add regression coverage for production stop retries, mixed windows, delayed
claims, current-session fallback, recovery, capacity, and queued operations.
Update window API fixtures for the creation result's initial tab identities.
Validation: extension 1862 passed (103 skipped), plugin 276 passed; both
TypeScript checks and production builds passed.
Use an explicit standard-handle inheritance list for daemon startup and the
Windows update helper. Require and verify breakaway before resuming a
background daemon, with an actionable error for restrictive host Jobs.
Share direct startup and its readiness deadline across explicit and
automatic entry points, retain child ownership through startup, and reap
Unix children after handoff.
Add native Windows EOF, Job lifetime, concurrency and failure regressions
to CI, and document persistent host setup.
Refs #268
Track prepared starts with stable request handles, durable plugin ownership, monotonic cancellation, and retryable cleanup. Retain delayed and failed startup resources until cleanup is confirmed, without touching other sessions.
Add regression coverage for lost replies, killed CLI processes, delayed creation, failed cleanup, restart recovery, archive and unload, capacity accounting, and reused session IDs.
Fixes#245
Preserve the streamlined skill workflow and document background support for both viewport and full-page screenshots. Keep Canvas capture guidance and remove the outdated visibility requirement for Agent full-page capture.
