Distinguish absent CLI directories from unreadable directory counts and truncated slots while preserving known PE headers and readable CLI data.
Retain environment-entry coverage in the Darwin parser and classify restricted empty, unavailable and ambiguous environments at the native boundary. Keep cleanup fail-closed; code-signing flags do not establish ownership.
Validation: 116 managed source tests, 13 ownership tests, native Swift parser probe and two live Darwin run-token tests; build, static checks and docs checks pass. Restricted-flag cases use parser fixtures; no real restricted capture is claimed. Related to #2035.
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.
Cancelling the macOS process-ownership helper build left swiftc object files
in TMPDIR. Node's execFile sends SIGTERM on abort and rejects before the
child exits, and swift-driver runs each frontend job in its own process
group: on SIGTERM the driver exits while a job keeps writing, so REA removed
its root while objects were still being written outside and inside it.
Add an opt-in `stopSignal` to execFileOutput that stops the process with the
caller's signal on abort or timeout and settles only after it exits. Swift
helper builds stop swiftc with SIGINT, on which swift-driver stops its jobs
and deletes their objects, and point TMPDIR inside the root cleanup removes.
Fixes#1173
