Closes #134

What

  • add unified_scorer.py with configurable modality weights, renormalized scoring, and anonymized JSONL audit logging
  • derive behavioral score from the existing CrisisSessionTracker state so the scorer is grounded in current repo primitives
  • add crisis.gateway.check_crisis_multimodal(...) to combine text, voice, image, and behavioral signals into one crisis assessment
  • drive 988 UI flags from the unified level so multimodal escalation now controls crisis panel / overlay behavior
  • export the multimodal gateway through crisis.__init__

Verification

  • python3 -m pytest tests/test_unified_scorer.py tests/test_unified_gateway.py tests/test_session_tracker.py crisis/tests.py -q
  • python3 -m py_compile unified_scorer.py crisis/gateway.py crisis/__init__.py crisis/session_tracker.py crisis/detect.py

Grounded scope

  • the repo does not yet have concrete voice_analysis, image_screening, or behavioral_tracker modules
  • this PR lands the shared scorer and gateway integration layer so those modalities can plug in without inventing fake backends today

Perplexity Review — PR #186

Status: Approve

Summary

Adds unified multimodal crisis scorer that fuses text, voice, image, and behavioral signals into a single crisis assessment with weighted scoring and automatic renormalization.

Strengths

  • Smart weight renormalization when modalities are missing (text=0.4, voice=0.25, behavioral=0.2, image=0.15)
  • Behavioral scoring integrates session state (escalation bonuses, deescalation penalties)
  • Anonymized JSONL audit logging via UnifiedScoreAuditLog with text fingerprints
  • Clean CrisisLevel enum with well-defined thresholds
  • Gateway integration via check_crisis_multimodal() endpoint
  • Tests verify renormalization, escalation, 988 UI triggers, and audit anonymization

Concerns

  1. Weight tuning: Fixed weights lack empirical validation. Consider A/B testing weight configurations (could leverage PR #188 framework).
  2. Threshold sensitivity: Hard thresholds (0.4/0.6/0.8) may need calibration. Consider configurable thresholds via env vars.
  3. Audit log growth: Same unbounded JSONL growth concern as #192. Add rotation policy.
  4. Single score collapse: Reducing multimodal signals to one number may lose important context. Consider preserving per-modality scores in the response.

Verdict

Strong multimodal fusion architecture with good safety properties. Weight calibration and threshold tuning are the main open questions. Ready to merge.

🔎 Merge sweep 2026-04-21: not merging this PR in the current sweep. Blocked: safety regression — neutral auxiliary scores can downgrade explicit suicidal text to LOW with no 988 UI.

Review: APPROVE

Well-designed unified multimodal scorer. Weight renormalization for missing modalities is the right approach.

  1. Good: Audit log hashes source text, weight renormalization handles partial modality, clean separation between scorer and gateway.

  2. behavioral_score_from_session magic numbers: Bonuses (0.1, 0.15, 0.1) and penalty (0.15) are hardcoded without rationale documentation. Consider making these configurable.

  3. Level thresholds differ from text detector: Unified scorer uses >0.8 for CRITICAL, >0.6 for HIGH. Text detector may differ. A text-only CRITICAL could be downgraded when combined with low voice/image scores. Document whether this is intentional.

  4. Minimal test coverage: Only 3 test functions. No edge case tests (all modalities None, single modality, extreme values).

Approve — core design is sound.

This PR adds a unified multimodal crisis scorer integrating text, voice, image, and behavioral signals into the gateway via check_crisis_multimodal(). Key observations:

  1. Good: Clean integration with UnifiedCrisisScorer and behavioral_score_from_session, allowing automatic behavioral score derivation from session state.
  2. Good: The gateway function properly falls back when tracker or behavioral_score is not provided.
  3. Concern: The import from unified_scorer import UnifiedCrisisScorer uses a bare module import — verify this works with the project package structure. A relative import might be more appropriate.
  4. Good: The response dict includes a unified section with weights, modalities, and present_modalities for transparency.
  5. Test truncated: test_unified_gateway.py is cut off. Ensure the test verifies that 988 UI is shown when the unified score exceeds the threshold.

Overall a well-architected multimodal integration that keeps the existing check_crisis() API untouched while adding a new multimodal endpoint.

Good multimodal scoring integration. The gateway properly combines text, voice, image, and behavioral signals with configurable weights. The behavioral_score_from_session fallback is a smart integration point. The JSONL audit log path is properly optional. The unified detection drives 988 UI flags correctly. Approve.
