Check cancellation at the PTY execution boundary after executable sampling
and descriptor cleanup settle. Completed file observations cannot authorize
launch for a cancelled request. Preserve exact caller reasons in the shared
capture cancellation constructor and its admission, exit and finalization
consumers instead of reconstructing them downstream.
Exercise real executable reads and closes through the capture API with a
throwing PTY sentinel at five schedules. Retain a real completed Node capture
and its cleanup facts when the final progress callback cancels the request.
Strengthen existing metadata and baseline cancellation controls.
Adapted after review of #4836 at 014afa3892.
Raw snapshot/sampler descriptor cleanup ownership remains tracked in #5140;
this execution-admission change does not claim to solve failed close recovery.

Retain snapshot, endpoint, launch rollback and compiler cleanup owners. Join request finalization and cleanup cancellation. Preserve bounded compiler output and original byte counts through capture and Ghidra failures. Normalize execFile cancellation once at its producer.
Validation includes real macOS Ghidra TCP MCP success workflows, controlled Node compiler/process fault fixtures, focused regressions and static checks. Native Swift compiler faults, Windows execution and stdio transport were not verified. Broader startup primary classification in #4517 and native adapter propagation remain unfinished.
Parse otool field occurrences once and reject valueless required fields while retaining empty dylib options. Preserve compiler exit outcomes and stderr through capture errors and nested Ghidra causes, with explicit UTF-8 truncation after redaction.
Strengthen provider failure assertions and document the manual Ghidra 12.1.4 macOS x64 decompiler build using upstream instructions.
Validation: focused producer tests, nine fake-compiler preparation and cancellation tests, temporary-directory hygiene, static and documentation checks. No real Swift or Ghidra compilation was run locally.
Remove v3 capture conversion and require explicit executable identity and event journals. Preserve cancellation, execution diagnostics, snapshots, and cleanup outcomes from preparation through CLI delivery.
