[Candidate / unverified] Solution for 6a066822-47ce-4a89-9d9e-552fd28f53cf: After emitting any terminal failure result, abort further stages synchronously (

## Support semantics This is a **candidate / unverified** Solution from the KFA Solution Factory Tier-2 gate. It is source-grounded research material, not an Outcome, and does **not** claim independent reproduction or confirmed field success. ## Cause process.exitCode schedules an exit code for graceful process termination but does not halt current synchronous control flow; uncaughtException handlers that do not rethrow or exit allow the main script to continue, which Node documents as unsafe. ## Steps 1. Identify all post-crash stage entry points and side-effect seams (upload, publish APIs). 2. Set a terminal flag when writing a failure result; throw a typed abort at each subsequent stage boundary if the flag is set. 3. At top level, catch the abort and return the already-written result without overwriting it. 4. Prefer process.exit() only when stdout/stderr flush requirements are met; otherwise combine exitCode with hard abort before side effects. 5. Update tests to stub side-effect seams and assert zero calls after simulated uncaughtException. ## Expected result After a recorded fatal, no later stage runs and no live artifact is published while the result file reports failure. ## Misleading approaches - Assuming process.exitCode = 1 inside a handler stops the function or pipeline immediately. - Crash-path tests that only assert a result JSON was written. ## Limitations - Guards do not cancel in-flight async work or detached child processes started before the fatal. - process.exit() can truncate buffered stdout; adapters needing flush may need a different abort strategy. - No vendor-specific orchestrator documentation was fetched for this problem. ## Unknowns - Exact adapter codebase and stage ordering. - Whether the orchestrator ignores exit code when a result file exists. ## Evidence claims - (documented_platform_behavior) Assigning process.exitCode does not immediately terminate the process; Node expects the process to exit gracefully when no further event-loop work remains. — https://nodejs.org/api/process.html - (documented_platform_behavior) Code that only sets process.exitCode inside an error handler can continue running subsequent synchronous statements in the same turn unless it throws or calls process.exit(). — https://nodejs.org/api/process.html - (documented_platform_behavior) Node warns that resuming after uncaughtException without proper handling is unsafe, supporting the need for an explicit abort rather than logging and continuing. — https://nodejs.org/api/process.html
