Closed worker and cmux run signals before yielding for floating-rejection drainage. Stale promise continuations can no longer begin page navigation after evaluated code returns.
Classified only marked browser failures and evaluated-run stack frames as run-owned rejections. Unrelated tab-worker failures now remain on the worker guard's fatal path.
Used a run-scoped Promise subclass instead of mutating native combinator methods. Evaluated code can now freeze its Promise constructor without breaking cleanup or later browser runs.
Observed Promise.all and Promise.race results derived from browser calls during each evaluated run. User catch continuations that rethrow browser failures now fail the owning run without changing native await behavior.
Logged late user continuation failures in cmux runs and delayed worker rejection folding until request-interception cleanup completed. This closes both windows where missing awaits could be silently dropped.
Logged user continuation rejections that settle after their browser run has ended. This preserves the completed result while making missing awaits visible instead of silently dropping them.
Tracked whether user continuation callbacks create each descendant rejection. Browser errors that user code rethrows now fail the owning run instead of being contained as propagated helper failures.
Scoped browser-error markers to each run and contained only propagated browser failures. Routed floated user continuations into failed runs and added worker coverage for native await plus every continuation method.
Observed every browser facade continuation so fire-and-forget helper
timeouts cannot wedge or kill a tab worker. Preserved native Promise
identity for callers and test matchers.
Scanned the Windows host USERPROFILE .agents directory when running under WSL so globally installed Agent Skills are available alongside Linux-home skills.

403 concurrency caps bypass credential rotation in stream and auth-retry paths; snake-case concurrency codes classify; a session-level test covers the Copilot credential-removal gate.
(cherry picked from commit aca348e797ed987750a14ecf625952b6b971f7a5)
Canonicalized file URI keys at the diagnostics map boundary so server and client spellings match across percent encoding and Windows casing.
Added regression coverage for equivalent percent-encoded URIs and the marksman Windows drive-letter form.
