The shell exited before error handling ran
An error-handling branch is useful only when the shell can reach it under the exact failing invocation.
What happened
A shell launcher captured a failing child's standard error, then exited at the child command before replaying that error or recording provider health because automatic exit-on-error was active.
2 prompts, in order
- Prove the failure branch is reachable A launcher contains recovery logic but shows nothing when a child fails.
- Drive failure through the actual launcher The launcher now captures the failed child result without premature termination.
1Prove the failure branch is reachable
- Run it when
- A launcher contains recovery logic but shows nothing when a child fails.
- It asks you for
- The complete dispatch statement, shell options, surrounding condition, redirections and recovery code.
- You get back
- The exact point where the shell terminates and a bounded repair that preserves normal strictness.
- It refuses if
- Do not analyze a simplified child invocation that changes the relevant shell context.
<stance> Your job is to separate an observed failure from a convincing explanation that has never been checked. Keep the reader's actual system in view. A result is useful when another person can repeat the observation and get a different answer if the proposed repair is wrong. </stance> <inputs> Ask for these before drawing a conclusion. Wait for anything essential that is missing. 1. The complete dispatch statement, shell options, surrounding condition, redirections and recovery code. 2. The exact user-visible symptom, including the original output and the time it was observed. 3. The implementation and launch conditions responsible for that output. Read the relevant source in full. 4. What may be changed safely, and which actions require the owner's approval. 5. Any existing verification that could distinguish the proposed cause from the alternatives. </inputs> <method> 1. Read the shell options active at dispatch and the complete command shape, including environment prefixes, input closure, error redirection and surrounding conditional structure. 2. Trace what happens when that child returns failure. Determine whether automatic exit-on-error terminates the parent before exit-code capture. A well-written recovery function is irrelevant if no failing execution reaches it. 3. Preserve the original error stream while investigating. Redirecting it into a file can make the failure disappear from the terminal if replay never runs. 4. Propose a narrowly bounded way to capture the child result and then restore normal strictness. Keep diagnostics, provider-health recording and temporary-file cleanup reachable. State how the exact invocation will establish each outcome. </method> <deliver> - OBSERVED: the behavior actually established, with the output that supports it. - EXPLANATION: what the observation settles and what remains unknown. - NEXT ACTION: one bounded action, its owner, and its expected result. - PROOF: the observation that would establish success, plus the result that would disprove it. </deliver> <refuse> Do not analyze a simplified child invocation that changes the relevant shell context. Do not invent measurements, defaults, source contents, or a successful run. Keep historical results separate from today's observations. Never transmit private inputs or perform a paid or external action just to complete this check. If access or authorization is missing, stop and name the exact missing condition. </refuse>
2Drive failure through the actual launcher
- Run it when
- The launcher now captures the failed child result without premature termination.
- It asks you for
- The existing launcher integration tests, child outcome, diagnostic stream and isolated health record.
- You get back
- Proof that failure reporting, repeated-failure state and cleanup all run through dispatch.
- It refuses if
- Do not copy test modules into the user's live configuration or claim a test launcher is a live provider.

Keep test health records and overridden modules in their declared scratch locations so the verification cannot modify the user's working setup. 2. Drive the already-supported failing child case and inspect the parent exit, replayed diagnostic and health record together. Confirm the failure reaches the original dispatch branch rather than a helper called directly by the test. 3. Repeat through the existing repeated-failure scenario and observe whether the health policy changes as intended. A healthy-looking record that never received failures would fail this check. 4. Confirm ordinary successful dispatch remains successful and temporary captures are cleaned up. Distinguish existing integration coverage from a fresh external-provider outage; the latter requires authorization and is unnecessary for this local repair. </method> <deliver> - OBSERVED: the behavior actually established, with the output that supports it. - EXPLANATION: what the observation settles and what remains unknown. - NEXT ACTION: one bounded action, its owner, and its expected result. - PROOF: the observation that would establish success, plus the result that would disprove it. </deliver> <refuse> Do not copy test modules into the user's live configuration or claim a test launcher is a live provider.

How you know it worked
A failing child must reach exit-code capture, diagnostic replay, health recording and cleanup through the actual launcher path. Verify ordinary success too. Reading the recovery branch or invoking its helper directly cannot prove the parent shell reaches it.
