fix ZeroGPU quota: reserve 45s not 180s per request, 384 max tokens, quota hint in UI

add explicit Send button (Enter alone is unreliable with Thai IME / mobile)

fix: hide UI events from API schema (same /info 500 bug)

EN disclaimer (DRAFT, verify before use) + going public

Update KB to ingredient_kb_v19 (enriched: therapeutic_bucket + otc_tier)

Add symptom->drug retrieval (OTC household remedies) so symptom queries get recommendations

Add ingredient KB grounding (indications/dose/legal); English UI chrome; keep Thai system prompt

API accepts base64 image (3rd arg) so images reach ZeroGPU

handle drug-identification intent (read package, do not screen)

scope lock: decline out-of-scope (X-ray/diagnosis/non-drug images) + scope label

explicit stateless /chat API (message, history_json) + UI with memory + new-chat button

multi-turn memory (ChatInterface messages) + convo-wide RAG

mini-RAG grounding + anti-hallucination system prompt

TMT trade-name lookup for grounding

robust gr.Blocks + explicit /chat api

PAI 4b ZeroGPU test chat
