Signal stderr is saved as restricted artifacts and included in status records. Recovered crashes are reported as degraded. Bash tests cover retry, timeout, artifact, and classification behavior.

Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: ⚪ Minimal · up to The change retries synchronous SIGSEGV exits within the original timeout and preserves diagnostics; no actionable merge-blocking risk remains after normal checks and review. Sequence Diagram(s)sequenceDiagram

In `@scripts/lib/agent-sync.sh`:
- Around line 461-464: Update the command execution around run_with_timeout in
the agent-sync flow to capture its non-zero status within an if condition,
rather than unconditionally restoring errexit with set -e. Preserve the caller’s
original errexit state while still assigning exit_code and allowing the caller
to handle provider failures.
In `@tests/unit/test-agent-sync-signal-retry.sh`:
- Around line 67-71: Update the fixture’s run_with_timeout helper to enforce the
recorded timeout rather than only logging it, make at least one provider attempt
exceed its computed timeout, and assert that the attempt is interrupted before
retry execution can continue past the original deadline.
