# AD-561 Intervention Classification Build Report

**Date:** 2026-04-30
**Status:** Complete
**Prompt:** `prompts/ad-561-intervention-classification.md`

## Summary

Implemented structured Counselor intervention classification. Counselor interventions now produce in-memory records with intervention type, agent, callsign, trigger, severity, detail, and timestamp; emit a dedicated intervention event; and are queryable through methods and an API endpoint.

Counselor assessment logic, intervention thresholds, event subscriptions, and persistence behavior were not changed.

## Files Changed

- `src/probos/cognitive/counselor.py`
  - Added `InterventionType`, `InterventionRecord`, intervention history, record/query methods, and instrumentation for therapeutic DM, cooldown, forced dream, and guidance directive paths.
- `src/probos/events.py`
  - Added `EventType.COUNSELOR_INTERVENTION`.
- `src/probos/routers/counselor.py`
  - Added Counselor intervention summary endpoint.
- `tests/test_ad561_intervention_classification.py`
  - Added 15 focused tests for enum values, records, event emission, intervention paths, filters, summaries, and endpoint behavior.
- `PROGRESS.md`, `docs/development/roadmap.md`
  - Updated AD-561 tracking.

## Sections Implemented

- `### Section 1: Create InterventionType enum and InterventionRecord`
  - Implemented in `src/probos/cognitive/counselor.py`; added `Enum` import and skipped redundant `time` import.
- `### Section 2: Add COUNSELOR_INTERVENTION event type`
  - Implemented in `src/probos/events.py`.
- `### Section 3: Add intervention tracking to CounselorAgent`
  - Implemented history initialization, `_record_intervention()`, event emission, and all four intervention-site recordings.
- `### Section 4: Add intervention query methods`
  - Implemented `get_intervention_history()` and `get_intervention_summary()`.
- `### Section 5: Add intervention API endpoint`
  - Implemented in `src/probos/routers/counselor.py` using `_get_counselor_agent()`.
- `## Tests`
  - Implemented in `tests/test_ad561_intervention_classification.py`.
- `## Tracking`
  - Updated `PROGRESS.md`, `docs/development/roadmap.md`, and this build report.

## Post-Build Section Audit

- `### Section 1: Create InterventionType enum and InterventionRecord` — complete; five intervention types and record dataclass exist.
- `### Section 2: Add COUNSELOR_INTERVENTION event type` — complete; event type exists in `EventType`.
- `### Section 3: Add intervention tracking to CounselorAgent` — complete; history list, recording helper, event emission, and therapeutic/cooldown/dream/directive instrumentation exist.
- `### Section 4: Add intervention query methods` — complete; history filtering and summary counts exist.
- `### Section 5: Add intervention API endpoint` — complete; endpoint returns summary and recent records through the Counselor router.
- `## Tests` — complete; 15 focused tests added.
- `## Tracking` — complete; tracker and build report updates added.

## Tests

- `d:/ProbOS/.venv/Scripts/pytest.exe tests/test_ad561_intervention_classification.py -v -n 0`
  - Result: 15 passed.
- `d:/ProbOS/.venv/Scripts/pytest.exe tests/test_ad561_intervention_classification.py tests/test_counselor.py tests/test_counselor_activation.py tests/test_counselor_therapeutic.py -v -n 0`
  - Result: 143 passed.
- `d:/ProbOS/.venv/Scripts/pytest.exe tests/ -q -n 4 --dist=loadfile`
  - Result: 10200 passed, 18 skipped.

## Deviations

- Skipped the prompt's redundant `import time` instruction because `counselor.py` already imported `time`.
- Dropped the `hasattr(assessment, "trigger")` guard and used the typed `CounselorAssessment.trigger` field directly.
- Wrapped intervention event emission in warning-level log-and-degrade handling per the review recommendation.
- Added 2 tests beyond the prompt's 13 to cover endpoint enabled and no-Counselor behavior.
