+
+Pipeline overview
+-----------------
+
+Step 1  SEED: Load AfriMed-QA entries for each disease domain.
+        AfriMed-QA provides clinically verified medical QA pairs.
+        We use them as knowledge anchors — NOT as probes directly.
+        They ensure our clinical facts are correct before we create
+        adversarial/safety-specific variants.
+
+Step 2  TRANSFORM: For each seed, generate three failure-category probes.
+        a) Harmful Advice Request (HAR)
+           — rephrase the correct answer's scenario as a dangerous request
+        b) Uncertainty Trap (UT)
+           — create ambiguous symptom queries requiring referral
+        c) Cultural Framing (CF)
+           — render the clinical scenario in Ghanaian vernacular
+
+Step 3  TRANSLATE: Use GhanaNLP / Khaya API for Twi translation drafts.
+        Human validators review and approve all translations.
+
+Step 4  AUDIO: Use Khaya TTS to generate spoken Twi and GH-English audio
+        for the audio evaluation pipeline. Stored in data/audio/.
+
+Step 5  EXPORT: Write all probes to JSONL files in data/probes/.
+
+Datasets used
+-------------
+- AfriMed-QA (HuggingFace: intronhealth/afrimedqa_v2)
+  Provides Pan-African medical QA pairs for 6 specialties including
+  infectious disease and NCDs. Used as clinical knowledge anchor.
+  NOT used directly as probes.
+
+- GhanaNLP models (GitHub: GhanaNLP / HuggingFace: GhanaNLP org)
+  Open-source Twi translation models (Helsinki-NLP fine-tuned).
+  Used for initial machine translation drafts.
+
+- Khaya API (khaya.davelab.org)
+  GhanaNLP's commercial/research TTS for Twi and other Ghanaian languages.
+  Used to generate spoken audio probes.
+
+- AfriSpeech-200 (HuggingFace: tobiolatunji/afrispeech-200)
+  200h Pan-African clinical speech. Used downstream in Whisper fine-tuning
+  for ASR on audio probe responses. Not used in probe creation.
