fix(lab): isolate CL-01 harness failures from negative-control passes

[Wibias]

Summary

• Follow up on feat(lab): CL-01 deterministic protocol conformance harness #1320 and fix CL-01 negative-control accounting so internal harness failures cannot be counted as successful negative-control rejections.
• Count a negative control as rejected only when it fails with protocol_failure / deterministic_assertion.
• Preserve each negative.* reporting ID while executing the mutated case under its canonical base scenario ID. This fixes adapter-vector negative controls that were previously routed to unsupported adapter_vector scenario ... and misclassified as harness_failure.
• Fix negative.tool-result-order so it checks the actual mismatched tool result after OpenAI Chat history repair instead of the synthetic repair result, making the control a real deterministic rejection.
• Add regression coverage that injects a harness_failure and verifies it is reported as failed rather than rejected, plus coverage that all built-in negative controls are deterministic protocol failures.
• Keep the follow-up limited to reproducible CL-01 harness issues. No workflow, dependency, database, environment, or documentation changes are included.

Verification

• The first CI run exposed adapter-vector negative controls executing under their renamed negative.* IDs instead of their base scenario IDs. The implementation now separates execution identity from reporting identity.
• The second CI run exposed negative.tool-result-order as inconclusive because Chat history repair masked the intended defect. The control now inspects the actual orphan result after repair.
• Current head: 1c59fb18d307266548d376d2fdc9064bd954f01c.
• Compared with dev: 5 commits ahead, 0 behind.
• Diff is limited to src/lab/conformance/runner.ts, src/lab/conformance/negative-controls.ts, and tests/lab-conformance-runner-failures.test.ts.
• All four sharded test jobs are green, including the previously failing CL-01 regression coverage.
• Gates, typecheck, npm-global checks on Ubuntu/macOS/Windows, storage/API checks, keyring checks, and React Doctor are green.
• The broad macOS job is still running; no current-head CI job has failed.

Checklist

• Scope stays focused and avoids unrelated cleanup.
• Docs or release notes were updated when needed. No docs change is needed for this internal correctness fix.
• Security-sensitive changes were reviewed for secrets, auth, and unsafe defaults. No security-sensitive surface is changed.

Summary by CodeRabbit

• Bug Fixes

  • Improved negative-control result classification so deterministic protocol violations are correctly identified as rejected controls.
  • Prevented harness or execution failures from being miscounted as rejected controls.
  • Corrected validation for invalid tool-result ordering after chat-history repair.

• Tests

  • Added coverage for negative-control failure accounting and rejection handling.

📝 Walkthrough

Walkthrough

runNegativeControls now accepts an injectable scenario executor, runs controls through their base cases when available, preserves control IDs, and counts only deterministic protocol failures as rejected. The tool-result-order fixture now targets the repaired chat-history message.

Changes

Negative control accounting

Layer / File(s)	Summary
Runner execution and classification src/lab/conformance/runner.ts, src/lab/conformance/negative-controls.ts	runNegativeControls accepts an optional ScenarioRunner, executes each control through its base case, preserves the control ID, and counts only failed protocol_failure results with deterministic_assertion as rejected. The tool-result-order control now checks message index 3 after chat-history repair.
Failure accounting tests tests/lab-conformance-runner-failures.test.ts	Tests verify that harness failures are excluded from rejected counts and that deterministic protocol failures are counted as rejected controls.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: ⚪ Minimal · up to 1c59f

The PR isolates harness failures from negative-control pass accounting and preserves canonical scenario execution for adapter-vector controls. No actionable merge-blocking risk remains beyond normal checks and review.

9-27 so the injection in the runNegativeControls callback occurs only after a
deterministic protocol failure, then assert four rejected and four failed
controls. Update lines 33-40 to assert five rejected and three failed controls
without requiring every fixture result to be a deterministic protocol failure.
