 The PR appears safe to merge; no blocking correctness, security, or repository-rule violation remains. SummaryThe PR centralizes native backend-exit normalization and classification, identifies signed and unsigned Windows NTSTATUS values consistently, records the current Electron process signal separately from the durable crash journal, and includes localized native-fault context in crash reports.

In `@CHANGELOG.md`:
- Around line 13-17: Update both Unreleased changelog entries to reference PR
`#2267`: change the first entry’s parenthetical reference and make the Fixed entry
end with `#2267`, while retaining `#2250` only as a prior-issue reference in the
prose if needed.
In `@electron/src/renderer/src/components/report-bug.tsx`:
- Line 175: Replace the hardcoded native-fault cause text in the report-bug
component with the existing translation mechanism, adding a dedicated
translation key and corresponding localized value to all 21 Electron locale
bundles. Preserve the diagnostic meaning and interpolation behavior of the
generated bug report.
- Around line 145-153: Update the current backend failure section near
describeExitCode to detect a native fault using isNativeFaultExit with the
current crash record, and include the same no-Python-traceback explanation
already used by the later lastCrash section for NTSTATUS, SIGSEGV, and SIGILL
failures. Preserve the existing message and exit-code entries for non-native
failures.

A backend killed below Python leaves no traceback, only an exit code.
On Windows that code is an NTSTATUS, and the two desktop shells report
the same status differently:
Tauri Rust ExitStatus::code() -> i32 -> -1073741819
Electron Node -> the raw DWORD -> 3221225477
Both are 0xC0000005, STATUS_ACCESS_VIOLATION. The fault table held only
Rust's form, so the identical crash was a recognised native fault from
Tauri and an anonymous non-zero exit from Electron — which is how debpalash#2250
arrived titled "exit code 3221225477", with nothing in it saying the
backend had segfaulted. Signals split the same way: POSIX gives 11, Node
gives 'SIGSEGV', and the table only knew the number.
The fix is not to swap one representation for the other — both are real,
and the backend's own run-sentinel is a third producer. utils/nativeExit
normalises first and classifies second, and both shells now ask the same
question of the same table. backendCrash delegates to it, so the Tauri
path is unchanged and the two cannot drift apart again.
What changes for a user: the crash panel and the bug report say
"3221225477 (0xC0000005 STATUS_ACCESS_VIOLATION)" instead of a bare
number, and a native fault says outright that no Python traceback exists
so nobody hunts for one that was never written. The raw value is kept
first so it still matches the log and anything they searched for.
This does not stop crashes. It stops them being unidentifiable — six of
the twelve open issues are backend deaths sitting at needs-info.
Twenty tests: every fault in both representations, signals numbered and
named, and the boundaries that must NOT be called faults — SIGKILL is
the OS memory killer, SIGABRT is how a fatal CUDA error exits, and a
real-but-unlisted NTSTATUS is not invented into one.

The PR adds shared normalization for Windows NTSTATUS values and POSIX signals so Tauri and Electron classify native backend faults consistently. Crash details and bug reports retain raw values, add fault names, and state that native faults have no Python traceback. Human review should verify that unrestricted negative exit-code normalization cannot misclassify non-NTSTATUS values, while
SIGKILL,SIGABRT, and unknown NTSTATUS values remain non-faults.
