Transfer canonical leases through opening, session and storage boundaries. Keep response deadlines separate from actual completion, drain independent owners, and join late opening failure cleanup before confirming recovery. Remove error copies in favor of canonical primary/cleanup composition.
Preserve exact caller reasons, completed observations and independent physical failures through final-close cancellation and retry. Closes#4869.
Validation:155 tests pass across15 focused source, service, CLI subprocess and MCP files; static/docs/discovery1551 pass. Two original-revision controls fail as expected. Bounded authored-session public CLI comparison preserves equivalent Evidence and1282 reply token estimates; no real Chromium qualification or forced-termination recovery claim (#4659).
Own CDP transports from admission through observed close, retain failed
owners for retry, and keep active peers separate from pending cleanup.
Preserve primary errors and completed facts through final cancellation.
Forward passive Electron CLI cancellation and dispose browser, runtime and
scenario owners from CLI and MCP shutdown.

Share CLI boundary module evaluation in bounded forks while preserving fresh command instances and child processes. Keep module-mocked cleanup tests and source/compiled product catalog verification isolated, and update focused artifact selection.
