Model the requested signal setting a child termination marker before the launcher begins fallback handling. The regression proves close drains inherited stdio and propagates the original process error without sending a redundant SIGKILL.
This complements the post-check fallback-refusal race and restores the launcher's required 100% per-file statement and branch coverage.
Exercise both exitCode and signalCode arriving after the SIGTERM grace begins but before the bounded SIGKILL confirmation helper starts. This pins the fast path that avoids signaling an already-terminated child and restores the package's per-file 100% branch and statement coverage.
Keep the marker transition deterministic by withholding the synthetic exit event, matching the OS state race the defensive pre-check exists to absorb.
Bring the TUI branch onto master after PR #378 landed so PR #363 is evaluated against the current type-equivalence documentation contract.
Resolve the bilingual development-record overlap by regenerating the English/Chinese consistency record from the merged documents. This preserves the branch's built-subprocess guidance alongside master's expanded JSDoc type-equivalence rules.
Declare MoveFileExW's return value as Koffi int and model it as a numeric 32-bit Win32 BOOL. The previous Koffi bool declaration represented a one-byte C boolean and could read the native return register with the wrong ABI.
Test zero and nonzero results explicitly and assert the binding result type while preserving the existing write-through flags, error translation, and durable directory race behavior.
Update the workspace-edit Windows sidecar to the current permission preset description emitted by the ACP session configuration. The shared golden already carried this contract; only the native-Windows transcript retained the superseded wording.
Leave the platform-specific backslash path rendering unchanged so the sidecar continues to pin the one intentional Windows transcript difference.
Pass the fake descendant the parent process's stdout and stderr stream handles instead of Unix-style numeric file descriptors. This lets Windows duplicate the live ACP and diagnostic pipes so launcher shutdown can prove that inherited handles, buffered frames, and stderr all drain after the parent exits.
Observe the pending update promise before initiating shutdown as well, preventing a missing late frame from becoming a transient unhandled rejection before the assertion reports the fixture failure.
Treat a fallback kill refusal as successful termination when the child already carries an OS exit marker. Windows maps Node's supported signal names to forced termination, so the requested signal can end the process between the launcher error race and its fallback SIGKILL.
Drain inherited stdio, the ACP parser, and in-flight callbacks before propagating the original child error in either exit-race path. Preserve AggregateError reporting only for a refused fallback while the process is still live, and add a deterministic cross-platform regression for that ordering.
Remove the animated, dark, and light terminal captures and their bilingual RFC section. The implemented RFC retains the durable front-door decision and verification contract without carrying binary demo artifacts that need visual maintenance.
Tighten the package README ownership wording and refresh the bilingual consistency record so no repository link or prose claim refers to the removed files.
Copy an existing target's DACL onto the empty staging file before any content is written, then publish with ReplaceFileW so Windows replacement keeps the target security descriptor instead of inheriting the broader parent policy.
Keep new-file inheritance and POSIX mode behavior unchanged, retain the already-protected temp when a concurrently removed target requires rename fallback, and translate native errors into Node-style codes for the filesystem error boundary.
Add host-independent Win32 binding coverage, native Windows descriptor assertions, package documentation, and a bilingual implemented RFC that supersedes the earlier inheritance-only replacement claim.
Pass an explicit Linux platform to the two remaining SIGTERM-specific ladder tests instead of inheriting the host platform.
This keeps their synchronous-exit assertions focused on the POSIX middle and final rungs while the dedicated Windows case continues to verify the direct SIGKILL path.
Without the pin, native Windows coverage deterministically expected SIGTERM but observed the intended SIGKILL-only behavior.
Observe signal errors and bound the final forced-exit edge with disposeGraceMs so a refused or ineffective SIGKILL cannot leave disposal pending forever.
Apply the confirmation bound on POSIX and Windows, remove listeners and timers on every outcome, and update the ACP consumer contract plus the generated config catalog.
Cover emitted signal errors, synchronous kill exceptions, refused termination, and accepted termination that never reports exit.
Bring in the one-session surface manager landed through #376 after master advanced beyond the prior merge base.
Resolve the generated event-matrix overlap by regenerating from the merged TypeScript tree, preserving master's updated session declaration locations together with the TUI listener edges. Regenerate and verify the RFC index so both lifecycle updates remain represented.
Record the July 17 package split as an implemented bilingual feature RFC. The decision explains why TUI and stdio have separate terminal contracts, why concrete front-door selection belongs to composition, and how the TUI preserves existing session, tool-presentation, and lifecycle ownership.
Link the deterministic dark, light, and animated demos from the RFC so the assets have an in-repository owner. Cross-link the feature and testing decisions from the package README, then regenerate the RFC index and bilingual consistency record.
