+# Karthik EmpathRAG Core Dataset V2 Audit
+
+Date audited: 2026-05-05  
+Dataset path: `Data_Karthik/empathrag_core_dataset_v2`
+
+## Verdict
+
+Yes, we need this dataset and should use it.
+
+It is the first delivery that is large enough to make EmpathRAG Core look like a
+real ML/NLP system instead of only a rule-routed demo. It gives us:
+
+- 360 single-turn labeled prompts across all 14 routes.
+- 50 multi-turn scenarios.
+- 22 risky/ambiguous cases.
+- 11 resource profile additions.
+- Balanced train/dev/test split: 216/72/72.
+
+The single-turn data is immediately useful for the TF-IDF/logistic router and
+Eval A. The multi-turn data is useful, but weaker and needs a follow-up pass
+before it can be the strongest paper claim.
+
+## Ingest Result
+
+Command:
+
+```powershell
+.\venv\Scripts\python.exe -B eval\ingest_core_dataset_v2.py --delivery-dir Data_Karthik\empathrag_core_dataset_v2
+```
+
+Result:
+
+- Status: `pass_with_warnings`
+- Errors: none
+- Single-turn rows: 360
+- Multi-turn scenarios: 50
+- Risky/ambiguous rows: 22
+- Resource additions: 11
+
+Warnings:
+
+- 35 rows use `expected_usage_modes=none`.
+- All 35 are `out_of_scope`, so this is acceptable. Treat `none` as no retrieval expected.
+
+## Single-Turn Label Balance
+
+Route labels are well balanced:
+
+- Most routes have 25 rows.
+- `crisis_immediate`: 26 rows.
+- `general_student_support`: 24 rows.
+- `out_of_scope`: 35 rows.
+
+Safety tier distribution:
+
+- `support_navigation`: 145
+- `wellbeing`: 122
+- `high_distress`: 73
+- `imminent_safety`: 20
+
+This is strong enough for the class presentation and for preliminary Eval A.
+
+## Training And Eval A
+
+Training:
+
+```powershell
+.\venv\Scripts\python.exe -B eval\train_ml_router.py
+```
+
+Result:
+
+- Trained on 216 rows.
+- Model artifacts saved under `models/router/`.
+- Artifacts are local/ignored, so demo fallback remains safe if models are absent.
+
+Router test split:
+
+- Rows: 72
+- Model available: true
+- Rule route accuracy: 0.389
+- ML route accuracy: 0.903
+- ML tier accuracy: 0.889
+
+Full Core Eval A:
+
+- Rows: 360
+- Rule route accuracy: 0.389 CI95=[0.339, 0.439]
+- Hybrid route accuracy: 0.856 CI95=[0.819, 0.892]
+- Hybrid source org hit rate: 1.000
+- Unsafe generation count: 0
+- Pure validation/no-action count: 0
+- Ungrounded action count: 0
+
+Interpretation:
+
+The dataset makes the ML router contribution visible. This is good for the
+presentation. Do not overclaim it as final publication-quality route modeling;
+it is still synthetic and vocabulary-sensitive.
+
+## Bugs Exposed And Fixed
+
+The trained router initially overrode obvious rule routes because the confidence
+threshold was too low.
+
+Fixes made:
+
+- Raised ML router confidence threshold from `0.15` to `0.35`.
+- Moved `out_of_scope` rule detection earlier than anxiety/counseling keywords.
+- Added hard safety patterns for synthetic crisis shorthand:
+  - `doesn't feel survivable`
+  - `tonight ... survivable`
+  - `impulses loud`
+  - `impulses fast`
+  - `impulses unspecified`
+  - `spiraling fast ... impulses`
+- Added contextual high-distress signals:
+  - `panic attacks`
+  - `hopeless`
+  - `everything hollow`
+  - `ideation creeping`
+  - `goodbye texts`
+  - `mentioned goodbye`
+  - `refuse external help`
+  - `secrecy`
+- Added trajectory escalation reason for goodbye/farewell language in a high-risk context.
+- Fixed Eval B denominator so benign scenarios do not count as missed escalations.
+
+Regression:
+
+- `tests/test_v25_support_navigator.py`: 19 passed.
+
+## Multi-Turn Dataset Quality
+
+Eval B after harness fix and safety patches:
+
+- Scenarios: 50
+- Escalation scenarios: 4
+- Missed escalation count: 0
+- Missed escalation rate: 0.0
+- Unsafe generation count: 0
+- Pure validation/no-action count: 0
+- Ungrounded action count: 0
+
+Important caveat:
+
+Only 4 of 50 multi-turn scenarios actually require imminent/intercept
+escalation. That is too few for the headline multi-turn safety claim.
+
+The multi-turn set is useful for smoke testing, but not yet strong enough for
+the main paper story unless we clearly say it is preliminary.
+
+Issues:
+
+- Many auto-generated scenarios use shorthand/slang that can be hard to map
+  consistently.
+- Some `must_trigger_by_turn` values appear in benign/no-intercept scenarios.
+- Safety tier labels are noisy between `wellbeing`, `support_navigation`, and
+  `high_distress`.
+- Several scenarios mix routes without realistic narrative continuity.
+
+## Resource Profile Additions
+
+The 11 resource additions are useful as a source-target map and future registry
+input, but should not be auto-merged.
+
+Reasons:
+
+- Some contacts are descriptive prose rather than normalized contact fields.
+- Several entries duplicate resources already in our verified UMD registry.
+- Resource details need official page re-verification before runtime use.
+
+Use them as review suggestions, not production registry rows.
+
+## What To Ask Karthik For Next
+
+Ask for a focused `empathrag_core_dataset_v2_1` patch, not a full rewrite.
+
+Priority requests:
+
+1. Add 20-30 more multi-turn escalation scenarios.
+2. Ensure at least 25 of 50 multi-turn scenarios require a real escalation or
+   hard redirect.
+3. Add more peer-helper escalation scenarios.
+4. Add dependency and secrecy escalation scenarios with clear turn-by-turn
+   expected behavior.
+5. Add help-rejection scenarios where the system must redirect to human support.
+6. Reduce unrealistic slang/shorthand in at least half the multi-turn cases.
+7. Make `must_trigger_by_turn` blank/null for scenarios that should never
+   escalate.
+8. Add a short label rubric explaining the difference between:
+   - `wellbeing`
+   - `support_navigation`
+   - `high_distress`
+   - `imminent_safety`
+9. Keep the single-turn set mostly as-is.
+10. Mark out-of-scope rows with `expected_usage_modes=none`; this is acceptable.
+
+## Presentation Use
+
+Use these results in the class presentation:
+
+- Single-turn dataset size and balance.
+- Rule vs ML route accuracy improvement.
+- Zero unsafe generation / no-action / ungrounded-action counts in this eval.
+- Multi-turn eval as preliminary and now correctly measured.
+
+Do not present the multi-turn benchmark as final strong evidence yet. Present it
+as the next tightening step and show that it already exposed safety-language
+coverage gaps, which we fixed.
