Add Moriarty Probe external adapter and probe-disagreement fixture

[jeffmoriartyai-max]

Implements an external GuardBench adapter for the Moriarty Probe (4yourhuman.com/research/llm-self-knowledge-v1) as the third external slot after Mem0 Platform and Zep Cloud. The adapter maps action signatures and seeded evidence to allow/warn/block via the paper's preference-dimension coding scheme (COMP/PRES/CAPX/HELP/EXPL) and emits the standard GuardBench result fields plus probe-specific extension fields (probe_method, revealed_dimensions, gap_score, confidence, latency_ms, cost_usd, false_block_note, false_allow_note).

The v1 implementation is deterministic and credential-free: it classifies actions and computes gap scores locally from scenario inputs. The coding scheme and probe-method taxonomy are preserved verbatim from the paper. A future revision will swap the local classifier for a live call to the Moriarty Probe API without changing the schema.

Adds benchmarks/fixtures/ as a directory for external adapters to contribute candidate scenarios. probe-disagreement.json is the first fixture: a case where direct self-report (a memory stating a policy) contradicts behavioral evidence (tool events showing the policy was repeatedly violated, with one production failure). The probe is designed to detect this category of disagreement.

Validation passes locally:

• adapter-registry:validate (4 adapters)
• adapter-module:validate (Moriarty Probe loads; setup/decide/cleanup detected)
• adapter-self-test (10/10 contract rows, decisionAccuracy 0.40, redactionLeaks 0, p50 latency 0.32ms)
• external conformance run passes alongside Audrey Guard, No Memory, Recent Window, Vector Only, and FTS Only baselines

Summary

Thanks for shipping this. I’m going to hold merge for two concrete fixes.

1. The PR says the probe-specific fields are emitted unchanged for downstream consumers, but validateAdapterResult() currently normalizes adapter output down to the standard GuardBench fields only. That means probe_method, revealed_dimensions, gap_score, confidence, latency_ms, cost_usd, false_block_note, and false_allow_note are dropped before they reach the result row/raw artifact. Either the harness needs an explicit extension-field passthrough shape, or the PR should stop claiming those fields survive the GuardBench path.

2. probe-disagreement.json expects revealed_dimensions: ["COMP", "EXPL"], while the deterministic cue set in moriarty-probe.mjs appears to produce COMP for the included memory/action text. If this fixture is meant to become an executable candidate scenario, the expected probe shape needs to match the adapter or the evidence text/cues need to be adjusted.

CI is approved and running now. After these are reconciled, I’ll review the scoring thresholds and registry behavior again.

CI is now back with a concrete failure in the Node jobs:

tests/guardbench.test.js > validates the GuardBench adapter registry

The test still expects the registry ids to be exactly:

['example-allow', 'mem0-platform', 'zep-cloud']

This PR adds moriarty-probe, so the registry test needs to be updated too. I’d make that explicit rather than loosening the test too much: keep asserting the known ids, just include moriarty-probe, and keep the adapter count/shape checks strict.

So the current fix list is:

1. Preserve or remove the claimed probe extension fields in the harness path.
2. Reconcile the COMP/EXPL expected fixture shape with what the deterministic cue set actually emits.
3. Update the adapter registry unit expectation for the new adapter id.

After that, rerun the failed Node jobs.

Thanks for the v2 push. Still holding merge. I’m not approving/running the untrusted workflow yet because the diff still has contract issues that should be fixed first.

Current blockers:

1. The branch is behind current master and mergeable=false. I merged the harness-side adapter extension support in Preserve GuardBench adapter extension evidence #46; please rebase/merge master so this PR is tested against the actual current GuardBench path.

2. The registry test is still not updated in this PR. benchmarks/adapters/registry.json adds moriarty-probe, but the existing registry unit expectation still needs to include that id explicitly and keep the shape/count assertions strict.

3. detectResolution() appears to suppress valid risk too broadly. Once a failed event with action overlap sets lastFailureIndex, the next succeeded event returns true if failedOverlap > 0.3. That condition is true by construction from the failed event, so an unrelated later success can mark the failure as resolved. The success event itself needs to match the action/failed command/resolution marker; reusing the failed overlap as a success condition is not safe.

4. probe-disagreement.json still expects revealed_dimensions: ["COMP", "EXPL"], but the v2 cue set looks like it will emit COMP and likely CAPX for the current fixture text (deploy plus failed). I still do not see an EXPL cue in the action/evidence corpus. Either the expected output needs to match the deterministic adapter, or the fixture evidence needs a real explainability/audit cue.

5. The PR body still has the template validation checklist rather than the exact commands/output from the v2 head. Please replace that with current validation after rebasing.

The direction is useful, but I’m going to keep this as an external experimental adapter until the diff, fixture expectations, and CI evidence line up.
