It captures asynchronous spawn failures, handles missing streams, and settles on the first error or close event. New tests cover error ordering and absent stdio handles. ChangesProcess probe hardening
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: ⚪ Minimal · up to This localized test-only change adds handling for probe child-process spawn failures while preserving existing behavior, and no actionable merge-blocking risk remains after normal checks and review. Poem

runHardeningSettlementProbe with an isolated temporary directory and an
uncreated child path at tests/adapters/process-transport.test.ts lines
1751-1753, and apply the same separate per-test setup for the event-order test
at lines 1780-1784 and the no-stdio test at lines 1824-1828. Ensure each absent
path is guaranteed missing and cannot collide with other runs.

There was a problem hiding this comment.
Each of the three new spawn-failure tests calls makeTempDirectory() inline to construct absent, but none retains or passes that directory to removeTempDirectory; the helper is a raw mkdtempSync with no cleanup registry. Consequently every suite execution leaves three agentbridge-pr010-* directories under the system temp directory, and repeated local or CI runs accumulate them even when all tests pass. Keep the parent path and remove it in a finally block in all three tests.
Useful? React with 👍 / 👎.

- Around line 1753-1754: Update the tests around runHardeningSettlementProbe to
store each parent directory returned by makeTempDirectory and remove it with
removeTempDirectory in a finally block, including the cases near lines 1754,
1783, and 1827; preserve the existing assertions and probe behavior.

Purpose
Stacked validation PR for:
PR025-CR-FINDING-A-PROBE-CHILD-ERROR-UNHANDLEDThis PR is intentionally narrow and quarantined.
It targets protected parent PR #25.
It does NOT target
main.It does NOT directly target protected PR #10.
Finding
Classification:
CURRENT P3The PR #25 hardening-settlement regression probe created a ChildProcess without
an
errorlistener.A real asynchronous spawn failure could therefore emit an unhandled
ChildProcess
errorevent, terminate or destabilize the Vitest worker, anddestroy attributable regression evidence.
Fresh independent validation also proved that EMFILE/ENFILE-class spawn
failures can leave
stdout/stderrabsent before the asynchronouserrorevent arrives. The bounded repair therefore also tolerates absent stdio handles
so the real spawn failure reaches the probe evidence path instead of becoming a
misleading TypeError.
Repair
The bounded repair changes only:
