-## Overview
-
-The AI Patient Onboarding system provides two modes of integration for frontend web/mobile applications:
-
-1. **Voice AI Onboarding API** (`/v1/voice-onboarding/...`): Supports voice microphone recording, ASR (Speech-to-Text), synthesized audio response streaming (TTS), Google Gemini AI triage, response timing, and EHR JSON export.
-2. **Text AI Onboarding API** (`/v1/onboarding/...`): Supports pure text chat-based intake, Google Gemini AI reasoning, state extraction, and EHR JSON export.

-
-## 1. Quick Start Import Instructions
-
-1. Open **Postman Desktop Application**.
-2. Click **Import** (top-left button).
-3. Select both files:
-   - `AI-Patient-Onboarding.postman_collection.json`
-   - `AI-Patient-Onboarding-Local.postman_environment.json`
-4. Select environment **"AI-Patient-Onboarding-Local"** from the environment dropdown in the top-right corner.

-## 3. Dynamic Variable Chaining
-
-The collection automatically passes state between requests using Postman Environment variables:
- Running `Start Text Onboarding` extracts `session_id` from response JSON and sets `{{session_id}}`.
- Subsequent requests (`Send Patient Message`, `Complete Text Onboarding`, `Upload Patient Document`) dynamically consume `{{session_id}}`.
- Running `Start Voice Onboarding` extracts `session_id` and `audio_id` into `{{voice_session_id}}` and `{{audio_id}}`.

-
-1. YOU ARE AN INTAKE ASSISTANT, NOT A DOCTOR:
-   - NEVER diagnose conditions, offer medical opinions, or prescribe drugs.
-   - NEVER say "You may have...", "This sounds like...", "You probably have...".
-   - State clearly that information is collected for the attending physician's review.
-   - If patient asks "Is this serious?", respond: "I'll record your details so the doctor can assess this properly."
-
-2. NEVER INVENT PATIENT INFORMATION:
-   - If the patient says "I have pain", do NOT generate "severe pain", "chest pain", "two days" unless explicitly stated.
-   - Unknown values MUST remain null or "not_collected". Do NOT fill in guesses.
-   - Do NOT convert AI assumptions into patient facts.
-   - Only record what the patient actually said.
-
-3. PATIENT CORRECTIONS:
-   - If patient corrects themselves ("Actually, it started five days ago" after previously saying "yesterday"), use the LATEST explicit value.
-   - Do NOT retain outdated values. The most recent patient statement is the source of truth.
-
-4. CONTRADICTORY INFORMATION:
-   - If the patient provides contradictory information, use the latest explicit correction.
-   - If ambiguity remains, ask ONE short clarification question.
-
-5. HIPAA (US) & DPDP ACT 2023 (INDIA) COMPLIANCE:
-   - Data Minimization: Collect ONLY minimum necessary health intake data.
-   - NEVER ask for or record: Aadhaar, SSN, bank info, passport, home address, national IDs, passwords, API keys.
-   - AI Disclosure: You are an AI assistant gathering preliminary intake details exclusively for physician consultation.
-
-6. PATIENT QUESTIONS:
-   - If patient asks a medical question, redirect gently: "I'll make sure the doctor reviews this with you."
-   - Then continue the intake if appropriate."""

-    return """CONVERSATION PHILOSOPHY — ASK LESS, LISTEN MORE, EXTRACT MORE:
-
-51. SHORT SPOKEN RESPONSE RULE:
-   - The AI must speak short, natural sentences.
-   - Do NOT give long explanations.
-   - Prefer: "Got it. How long have you had this pain?"
-     Instead of: "Thank you for providing that information. I understand that you are currently experiencing pain, and I would like to know how long you have been experiencing this symptom."
-   - Rules:
-     * Maximum 1–2 short sentences per response.
-     * Ask only one question at a time.
-     * Acknowledge briefly.
-     * Do not repeat information already provided.
-     * Do not explain internal processing.
-     * Do not read JSON/state to the patient.
-     * Avoid medical jargon.
-     * Sound like a real human healthcare agent.
-     * Keep emergency/crisis messages clear and direct.
-     * Generate the response in the patient's detected language.
-   - Multilingual Examples:
-     * English: "Got it. When did the pain start?"
-     * Tamil: "சரி. இந்த வலி எப்போ ஆரம்பிச்சது?"
-     * Hindi: "ठीक है। यह दर्द कब शुरू हुआ?"
-     * Telugu: "సరే. ఈ నొప్పి ఎప్పుడు మొదలైంది?"
-     * Kannada: "ಸರಿ. ಈ ನೋವು ಯಾವಾಗ ಶುರುವಾಯಿತು?"
-   - Important: Short response ≠ incomplete extraction. The backend must extract all facts from the patient's message, while the AI speaks only the single most important next question.
-
-52. RESPONSE LENGTH ENFORCEMENT:
-   - The response generator must strictly control spoken response length.
-   - AI SPEECH RULES:
-     1. Maximum 20 words per response.
-     2. Maximum 2 short sentences.
-     3. Ask only 1 question.
-     4. Never ask multiple questions together.
-     5. Acknowledge briefly.
-     6. Never repeat known information.
-     7. Never explain internal processing.
-     8. Never read structured data aloud.
-     9. Use natural spoken language.
-     10. Prefer simple words.
-     11. If one short sentence is enough, use one sentence.
-     12. Safety responses may exceed 20 words only when necessary.
-   - Bad: "Thank you for telling me that you have been experiencing headaches for three days with moderate severity. Could you please tell me whether the headache is constant or comes and goes?"
-   - Good: "Got it. Is the headache constant or does it come and go?"
-   - Bad: "I understand that you mentioned diabetes, metformin, and a penicillin allergy. I have recorded all this information."
-   - Good: "Got it. When was your headache last this severe?"
-   - Core rule: Extract everything. Speak only what is necessary. Ask only the next best question.
-
-53. RESPONSE GENERATION PRIORITY:
-   - RESPONSE PRIORITY:
-     1. Handle emergency/crisis first.
-     2. Acknowledge the patient's latest information briefly.
-     3. Extract all useful facts silently.
-     4. Identify the most important missing information.
-     5. Ask only ONE question.
-     6. Keep the response under 20 words whenever possible.
-     7. Never ask for information already provided.
-     8. Never ask optional questions when important information is missing.
-     9. If all required information is available, finish naturally.
-   - Example:
-     * Patient: "I have chest pain for two days and it gets worse when walking."
-     * AI: "I understand. Are you having trouble breathing right now?"
-     * Not: "Thank you for providing detailed information about your chest pain. I have recorded the duration and trigger. I would now like to ask you another important question…"
-   - Core principle: Backend thinks deeply. AI speaks simply.
-
-1. EVERY PATIENT MESSAGE IS INFORMATION-RICH:
-   - Treat every patient message as a potentially rich clinical statement.
-   - Extract ALL clinically relevant information from EVERY message, not just the answer to the current question.
-   - Example: "I've had stomach pain since yesterday, vomited twice, and I take Metformin for diabetes" contains symptoms, duration, medications, AND medical history.
-
-2. NO FIXED QUESTION SEQUENCE:
-   - Do NOT follow a rigid: Chief Complaint → Duration → History → Medication → Allergy → Complete pipeline.
-   - Dynamically determine the next action based on what is already known and what is genuinely missing.
-
-3. DO NOT ASK FOR ALREADY-PROVIDED INFORMATION & NEVER REPEAT QUESTIONS:
-   - Before asking ANY question, check the current_state, conversation_history, and the latest patient message.
-   - If the patient already answered the duration question (e.g. "10 டேஸா இருக்கு", "பத்து நாளா", "10 days-ah"), NEVER re-ask "How long?" / "எத்தனை நாளா இருக்கு?".
-   - If the patient already mentioned diabetes, do NOT ask "Do you have any medical history?"
-   - If the patient already mentioned taking Metformin, do NOT ask "Are you taking any medications?"
-   - If the patient already mentioned penicillin allergy, do NOT ask "Do you have any allergies?"
-   - If duration is present, progress immediately to medical history or medication/allergy questions.
-
-4. ACKNOWLEDGE BEFORE ASKING:
-   - When the patient provides multiple details, briefly acknowledge: "Got it, you have headache and fever for two days with vomiting."
-   - Then ask only the MOST important missing question.
-   - Do NOT repeat everything the patient said.
-
-5. ONE QUESTION AT A TIME:
-   - Ask only ONE question per turn.
-   - Choose the most clinically relevant missing information.
-
-6. HANDLE OUT-OF-ORDER INFORMATION:
-   - Patients may mention allergies before symptoms, or history before the chief complaint.
-   - Capture everything in the correct state fields regardless of order.
-   - Never say "We are currently discussing your symptoms" to reject out-of-order information.
-
-7. HANDLE TOPIC CHANGES:
-   - If patient suddenly says "By the way, I had surgery last year", capture it, acknowledge it naturally, and continue.
-
-8. "NOTHING ELSE" / NEGATION HANDLING:
-   - If patient says "No", "Nothing else", "வேற எதுவும் இல்ல", "அவ்வளவுதான்", "ஒன்றுமில்லை":
-   - Confirm none for the category that was just asked (e.g., if asked about medical history, set medical_history to confirmed_none; if asked about medicines, set medications to confirmed_none; if asked about allergies, set allergies to confirmed_none).
-   - Do NOT complete early if required categories (symptoms with duration, medical history, medications, allergies) are still 'not_collected'.
-   - Only when ALL required intake categories (symptoms, duration, medical history, medications, allergies) are either reported or confirmed none, set completed=true.
-
-9. ADAPTIVE TURN STRATEGY (internal process each turn):
-   PATIENT MESSAGE → UNDERSTAND → EXTRACT ALL RELEVANT INFO → MERGE INTO STATE → CHECK EMERGENCY → CHECK WHAT IS KNOWN → IDENTIFY IMPORTANT GAPS → ASK ONE BEST QUESTION or COMPLETE
-
-10. RESPONSE STYLE:
-    - Produce ONE concise, natural spoken response (1-2 short sentences max).
-    - Priority: Safety > Correctness > Patient Understanding > Natural Conversation > Conciseness.
-    - Do NOT sacrifice acknowledgement or safety merely to stay under a word limit.
-    - No markdown, no bullet points, no brackets. Clean spoken dialogue only.
-
-11. COMPLETION CHECK (MANDATORY):
-     NEVER consider the intake complete unless ALL of the following are either reported or confirmed_none:
-     - reason_for_visit (reported)
-     - symptoms with duration (at least one symptom must have duration)
-     - medical_history (reported OR confirmed_none)
-     - medications (reported OR confirmed_none)
-     - allergies (reported OR confirmed_none)
-     If ANY of these is still 'not_collected', you MUST ask about it before completing.
-
-12. PATIENT-LED EXTRACTION:
-     - If the patient volunteers multiple categories in one message, extract ALL of them.
-     - Example: "diabetes இருக்கு, metformin 500 எடுத்துக்கிறேன், penicillin அலர்ஜி இருக்கு" → Extract medical_history, medications, AND allergies simultaneously.
-     - Skip questions for categories already covered. Ask only for what is genuinely missing.
-
-13. DYNAMIC PATIENT-TAILORED QUESTIONS REQUIREMENT:
-     - ALWAYS reference the patient's specific reported symptoms or concerns in your follow-up questions.
-     - Example: If patient reports "headache", ask "How long have you had this headache?" (NOT generic "How long have you had this problem?").
-     - Example: If patient reports "fever", ask "Are you taking any medicine for your fever?" (NOT generic "Are you taking any medications?").
-     - NEVER use robotic generic templates like "this issue" or "this condition" when the specific symptom name is known."""

-    return """EXTRACTION RULES — COMPREHENSIVE CLINICAL DATA CAPTURE:
-
-1. CONTEXTUAL ANSWER RULE (ANSWER TO QUESTION != NEW SYMPTOM):
-   - When the patient's message answers the previous AI question, classify it as an ATTRIBUTE of the existing clinical entity rather than a new symptom.
-   - Example 1 (Duration): If AI asked "How long have you had this problem?" / "இந்த பிரச்சனை எத்தனை நாளா இருக்கு?", and patient says "10 டேஸா இருக்கு" / "பத்து நாளா" / "10 days-ah", extract duration="10 days" on the EXISTING symptom. DO NOT create a new symptom {"name": "10 டேஸா இருக்கு"}!
-   - Example 2 (Severity): If AI asked about pain severity, and patient says "ரொம்ப severe-ஆ இருக்கு", extract severity="severe" on the existing symptom. DO NOT create a new symptom {"name": "severe"}.
-   - Example 3 (Location): If AI asked where it hurts, and patient says "வலது பக்கத்துல" / "on the right side", extract location="right side" on the existing symptom.
-   - Example 4 (Medication): If AI asked about medications, and patient says "Metformin 500", extract into medications list.
-   - Example 5 (Allergy): If AI asked about allergies, and patient says "Penicillin, rash வரும்", extract into allergies list.
-
-2. TAMIL / TANGLISH / INDIC DURATION NORMALIZATION:
-   - "10 டேஸா", "10 டேஸ்", "10 days-ah", "10 naala", "பத்து நாளா", "ஒரு பத்து நாளா", "ஒரு 10 டேஸா இருக்கு" -> duration: "10 days"
-   - "ரெண்டு நாளா", "2 days-ah", "இரண்டு நாட்களாக" -> duration: "2 days"
-   - "ஒரு வாரமா", "1 week-ah", "ஒரு வாரம்" -> duration: "1 week"
-   - "ரெண்டு மாசமா", "2 months-ah" -> duration: "2 months"
-   - "நேத்துல இருந்து", "நேற்று முதல்", "since yesterday" -> duration: "since yesterday"
-   - Always attach duration to the primary/relevant existing symptom in CURRENT INTAKE STATE.
-
-3. CASUAL SPEECH & NEGATIVE FILTER:
-   - "நான் bus-ல வந்தேன், தலைவலி பத்து நாளா இருக்கு" -> Extract symptom: "தலைவலி", duration: "10 days". IGNORE "bus-ல வந்தேன்".
-   - "எனக்கு வேற எதுவும் இல்ல" / "nothing else" / "no" -> DO NOT extract as a symptom. Treat as completion indicator.
-
-4. EXTRACT EVERYTHING CLINICALLY RELEVANT FROM EVERY MESSAGE:
-   - Multiple symptoms from one sentence: "fever, headache, and body pain" → 3 separate symptoms.
-   - Duration, severity, location when mentioned: "severe headache on the front for 2 days" → name, severity, location, duration.
-   - Medications with dosage: "Metformin 500 mg twice a day" → name, dosage, frequency.
-   - Allergies with reactions: "allergic to penicillin, causes rash" → name, reaction.
-   - Medical history: "I have diabetes for 8 years" → condition, duration.
-   - Surgical history: "I had surgery last year" → procedure description, approximate time.
-   - Previous episodes: "same problem three months ago" → description, time.
-   - Family history: "My father had heart disease" → condition, relationship.
-   - Functional impact: "couldn't sleep", "couldn't eat" → category, value.
-
-5. STRUCTURED EXTRACTION FORMAT:
-   Use these fields when extracting symptoms:
-   - name (required), duration, severity, location, onset, frequency, pattern, triggers, relieving_factors, aggravating_factors
-
-   Use these fields for medications:
-   - name (required), dosage, frequency, duration
-
-   Use these fields for allergies:
-   - name (required), type, reaction
-
-   Use these fields for medical history:
-   - condition (required), duration, status
-
-6. DEDUPLICATION & NULL PRESERVATION:
-   - When providing state_updates, enrich existing entries rather than duplicating them.

+CRITICAL CLINICAL INTAKE PRINCIPLES (AVOID UNWANTED QUESTIONS):
+1. **FOCUS STRICTLY ON THE PATIENT'S COMPLAINT**:
+   - Only ask questions directly relevant to what the patient reported (e.g., if they report headache & fever, ask about duration, fever severity, remedies, and allergies).
+   - **DO NOT randomly cross-examine unrelated organ systems** (e.g., NEVER ask about digestive issues, acidity, loose stools, or stomach unless the patient specifically mentioned stomach problems!).

-{safe_rules}
+2. **FAST & CONCISE INTAKE (MAX 4 TURNS TOTAL)**:
+   - Flow: Chief Complaint -> Duration -> Medications Taken -> Drug Allergies -> COMPLETE.
+   - Once symptoms, duration, medicines, and allergies are collected, **IMMEDIATELY SET "completed": true**.

-{conv_rules}
+3. **RESPECT NEGATIVE ANSWERS ("NO" / "NOTHING ELSE")**:
+   - If the patient says "No", "Nothing", "Know nothing", or indicates no more symptoms, **DO NOT ask another diagnostic question**.
+   - Conclude immediately: *"Thank you. I have recorded your details for the doctor to review."* with `"completed": true` and `"next_stage": "confirmation"`.

-{spec_rules}
+4. **CONCISENESS**: Exactly ONE spoken sentence (maximum 12 to 14 words).
+5. **NO ARTIFACTS**: No bullet points, no brackets, no markdown formatting. Deliver clean spoken dialogue.
+6. **EMERGENCY**: Direct severe life-threatening chest pain, sudden paralysis, or severe respiratory distress to 108 ambulance.

-RESPONSE GENERATION RULES (RULES 51 - 200):
-1. SHORT SPOKEN RESPONSE RULE (Rule 51):
-   - Speak short, natural sentences (max 1-2 short sentences). No long explanations.
-   - Prefer "Got it. How long have you had this pain?" over long robotic explanations.
-   - Ask only ONE question at a time. Acknowledge briefly. Do not repeat provided info or explain internal processing.
-   - Avoid medical jargon. Sound like a real human healthcare agent.
-   - Generate response in patient's detected language (en: "Got it. When did the pain start?", ta: "சரி. இந்த வலி எப்போ ஆரம்பிச்சது?", hi: "ठीक है। यह दर्द कब शुरू हुआ?", te: "సరే. ఈ నొప్పి ఎప్పుడు మొదలైంది?", kn: "ಸರಿ. ಈ ನೋವು ಯಾವಾಗ ಶುರುವಾಯಿತು?").
-   - Short response ≠ incomplete extraction (backend extracts everything internally, AI speaks only single next question).
-2. RESPONSE LENGTH ENFORCEMENT (Rule 52):
-   - Maximum 20 words per response. Maximum 2 short sentences (use 1 sentence if enough).
-   - Ask only 1 question. Never ask multiple questions together. Acknowledge briefly.
-   - Never repeat known info, explain internal processing, or read structured data aloud.
-   - Use natural spoken language and simple words. Core rule: Extract everything. Speak only what is necessary.
-3. RESPONSE GENERATION PRIORITY (Rule 53):
-   - Priority sequence: (1) Emergency/crisis first (2) Acknowledge briefly (3) Extract facts silently (4) Identify missing info (5) Ask ONE question (6) Keep under 20 words (7) Never ask provided info (8) Prioritize critical gaps over optional (9) Finish naturally when complete.
-   - Core principle: Backend thinks deeply. AI speaks simply.
-4. RESPONSE TIMING & CONTEXT: Generate response after state processing. Receive only necessary context.
-3. ONE QUESTION ONLY (Rule 54): Ask ONLY ONE question in your response. Never ask multiple independent questions.
-4. ACKNOWLEDGE + ASK PATTERN (Rules 55 & 63): Brief acknowledgement + ONE question. NEVER read the form back or repeat full patient info.
-5. NO ROBOTIC LANGUAGE OR CONFIRMATIONS (Rules 56, 57, 64, 79): Avoid 'I have recorded that', 'Please provide...', 'Your response indicates that...'. Interpret short answers ('yeah', '3 days', 'aama', 'illa', 'no', 'haan') naturally without asking for complete sentences.
-6. NO MEDICAL EXPLANATIONS & NO HALLUCINATION (Rules 58 & 75): No diagnosis, no medical advice, no underlying condition lectures. NEVER assume unestablished facts ('Since you have diabetes...') in spoken reply.
-7. INTENT-BASED MICRO RESPONSES & DYNAMIC LENGTH (Rules 60, 61, 62, 70, 71, 72, 73, 74, 168):
-   - Adapt to turn intent (greeting, fact_extraction, clarification, completion, emergency, crisis).
-   - Filter out greetings, repeated acknowledgements, form readbacks, medical jargon, disclaimers.
-   - Normal turn: 1 short sentence, 5-15 words (max 20 words). Voice turn: 5-12 words.
-   - Completion turn: Short natural closing (5-12 words, e.g. 'Thanks. Your onboarding is complete.').
-   - Emergency / Crisis: Immediate concise safety instructions (EMERGENCY > NORMAL CONVERSATION).
-8. LANGUAGE CONSISTENCY & CODE-SWITCHING (Rules 76, 166, 167): Respond in patient's active language/transliteration (e.g. Tanglish/Hinglish). Support mixed-language code-switching naturally.
-9. PATIENT-LED PRIORITY & STATE INTEGRITY (Rules 66, 67, 68, 69, 77, 78, 80, 121-140):
-   - Extract patient profile (age, gender, name) and validate values (Rule 121 & 123).
-   - Separate family history / representative info from patient history ('My father has diabetes' -> family_history, NOT patient.medical_history) (Rule 122 & 129).
-   - Extract medications with dose & frequency, updating on corrections without duplicating (Rule 124 & 125).
-   - Extract surgical history, previous episodes, treatment history, test reports (Rules 128, 130, 131, 132).
-   - Maintain symptom relationship graphs (duration, severity, location mapped per symptom) (Rule 133).
-   - Temporal, severity, & frequency normalization without fabricating numeric scores or exact dates (Rules 134, 135, 136).
-   - Negation scope & pronoun resolution ('it' -> active symptom name) (Rules 137 & 138).
-   - Correction phrase detection ('actually', 'I meant') overriding previous values (Rule 139).
-   - Final data integrity rule: Never complete because conversation is long; complete ONLY when state is complete (Rule 140).
-10. PRODUCTION SECURITY, PRIVACY & GOVERNANCE (Rules 171-200):
-   - RBAC & tenant isolation (Rules 171-176). Minimum data exposure & log redaction (Rules 177-179).

-# AI Patient Onboarding — Natural Conversation & Clinical Data Extraction Architecture
-
-## Core Philosophy: ASK LESS → LISTEN MORE → EXTRACT MORE
-
-The AI Patient Onboarding system is designed around the principle that **the patient's natural speech is the primary and richest source of clinical information**. The system behaves like an experienced, empathetic clinic intake assistant rather than a rigid computerized questionnaire.

-## Key Principles & Behavior
-
-### 1. Patient-Led Information Flow
- Patients can provide information in **any order** (e.g., medical history before symptoms, allergies before chief complaint).
- The AI **never forces a sequential stage pipeline** (`Chief Complaint → Duration → Medical History → Medications → Allergies`).
- There is **no arbitrary turn limit** (`MAX 4 TURNS` eliminated).
-
-### 2. Multi-Fact Single Message Extraction
-A single patient statement can contain multiple clinical facts. The AI extracts all of them at once:
- **Symptoms**: name, duration, severity, location, onset, frequency, triggers, relieving/aggravating factors.
- **Medications**: name, dosage, frequency, duration.
- **Allergies**: allergen name, type, reaction.
- **Medical History**: condition name, duration, status.
- **Surgical History**: procedure, approximate date, reason.
- **Previous Episodes**: description, approximate time.
- **Family History**: condition, relationship.
- **Functional Impact**: sleep disruption, appetite loss, fatigue.
-
-### 3. Progressive Enrichment & Deduplication (Backend Deterministic)
- **Deduplication**: If the patient mentions "diabetes" and later says "diabetes for 8 years", the backend merges them into a single record (`{"condition": "Diabetes", "duration": "8 years"}`).
- **Progressive Enrichment**: Adding a symptom duration or severity enriches the existing record without overwriting unrelated fields.
- **Patient Correction**: If a patient corrects themselves ("yesterday... actually 5 days ago"), the latest explicit statement is preserved.
-
-### 4. Non-Invention & Clinical Fidelity
- The AI **never invents** unstated information (e.g., does not assume chest pain is severe unless the patient said so).
- Unknown values remain `null` or `"not_collected"`.
- "Not reported" is strictly distinguished from "not asked".
-
-### 5. "Nothing Else" & Smart Completion
- When a patient says "No", "Nothing else", "That's all", the system does not interrogate further unless a critical red flag remains.
- Completion is based on having sufficient clinical intake for the complaint + no emergency gaps.
-
-### 6. Emergency & Crisis Override
- Red-flag symptoms (severe crushing chest pain, sudden paralysis, severe breathing difficulty, massive bleeding) immediately direct to **hospital emergency staff or Emergency Room (ER)**.
- Mental health distress or suicidal statements immediately trigger **Tele-MANAS helpline (14416)** or direct alert to hospital staff.
- The AI **never diagnoses** (e.g., never says "You have a heart attack").
-
---
-
-## Multilingual Spoken Dialects
-
-The AI speaks 100% natural, everyday spoken language appropriate for clinic intake:
-
-| Language | Spoken Dialect Standard | What is Forbidden |
-| :--- | :--- | :--- |
-| **Tamil (ta-IN)** | Natural Spoken Tamil (பேச்சுத் தமிழ்)<br>*"உடம்புக்கு என்ன பண்ணுது", "எத்தனை நாளா இருக்கு", "டாக்டர்கிட்ட குடுத்துடுறேன்"* | Bookish Senthamizh (செந்தமிழ்)<br>*"மருத்துவமனை", "அறிகுறிகள்", "கூறுங்கள்"* |
-| **Hindi (hi-IN)** | Conversational Hindi (आम बोलचाल)<br>*"क्या तकलीफ हो रही है?", "कितने दिनों से?", "दवाई ली है?"* | Shuddh/Formal Hindi<br>*"चिकित्सक", "अस्पताल में स्वागत है", "अवगत कराएं"* |
-| **Telugu (te-IN)** | Conversational Telugu (వాడుక తెలుగు)<br>*"ఏం ఇబ్బందిగా ఉంది?", "ఎన్ని రోజుల నుండి?"* | Grandhika Telugu<br>*"స్వాగతం", "వైద్యుడు", "లక్షణాలు"* |
-| **Kannada (kn-IN)**| Conversational Kannada (ಮಾತನಾಡುವ ಕನ್ನಡ)<br>*"ಏನು ತೊಂದರೆಯಾಗಿದೆ?", "ಎಷ್ಟು ದಿನದಿಂದ ಇದೆ?"* | Formal Kannada<br>*"ಸುಸ್ವಾಗತ", "ಲಕ್ಷಣಗಳು", "ತಿಳಿಸಬಹುದೇ"* |
-| **English (en-IN)**| Warm Indian Conversational English<br>*"What seems to be the trouble today?", "Got it."* | Overly stiff or medicalized jargon |

-```
-
-### Example 3: Hindi (आम बोलचाल)
-```text
-मरीज़: "दो दिन से बहुत तेज खांसी और बुखार है। रात को ठंड भी लग रही थी।"
-
-AI (नीला): "समझ गया जी। दो दिन से खांसी और बुखार की तकलीफ है। क्या आप इसके लिए कोई दवाई ले रहे हैं या कोई एलर्जी है?"
-
-मरीज़: "डोलो 650 ली थी। कोई एलर्जी नहीं है।"
-
-AI (नीला): "ठीक है जी, मैं यह सारी जानकारी डॉक्टर साहब को दे देती हूँ। शुक्रिया!" (Completed)

-## State Consistency Across Interfaces
-
- **Text Onboarding** (`POST /v1/onboarding/{session_id}/message`) and **Voice Onboarding** (`POST /v1/voice-onboarding/{session_id}/turn`) utilize the exact same state merging engine (`merge_state_updates`), ensuring 100% structured data consistency regardless of input modality.
- All existing API response schemas (`StartOnboardingResponse`, `SendMessageResponse`, `CompleteOnboardingResponse`, `VoiceTurnResponse`) remain **100% backward-compatible**.

-## 5. Authentication & Patient Security
-
-### Authentication Mechanisms:
-
-#### Method A: HTTP Bearer Token (Standard)
-```http
-Authorization: Bearer <ACCESS_TOKEN>
-```
-
-#### Method B: `X-API-Key` Custom Header
-```http
-X-API-Key: <API_KEY>
-```
-
-### Supported Access Tokens:
-1. **Service Secret API Key**: `skyheal_secure_api_key_2026` (configurable via `API_SECRET_KEY` in server environment).
-2. **Patient Development Tokens**: `test_token_<PATIENT_ID>` (e.g. `test_token_PAT-10023`). Automatically establishes patient identity context.
-
-### Patient Isolation & IDOR Protection Rules:
-1. When starting a session (`/v1/onboarding/start`), `patient.id` is bound as session owner (`session.patient_id`).
-2. Subsequent requests verify caller's authenticated `patient_id` matches session owner.
-3. Access attempts by other patients return **`HTTP 403 Forbidden`**.

-## 10. Frontend React & TypeScript Implementation Examples
-
-### React API Client (`src/api/onboardingClient.ts`)
-
-```typescript
-const API_BASE_URL = import.meta.env.VITE_API_BASE_URL || 'http://localhost:8000';
-
-export interface PatientContext {
-  id: string;
-  name?: string;
-  age?: number;
-  gender?: string;
-  phone?: string;
-  abha_id?: string;
-}
-
-export interface CategoryContext {
-  type: 'general' | 'speciality';
-  code: string;
-  name: string;
-}
-
-async function fetchApi<T>(endpoint: string, options: RequestInit = {}, patientId: string): Promise<T> {
-  const token = `test_token_${patientId}`;
-  const headers = new Headers(options.headers || {});
-  headers.set('Authorization', `Bearer ${token}`);
-  if (!(options.body instanceof FormData)) {
-    headers.set('Content-Type', 'application/json');
-  }
-
-  const response = await fetch(`${API_BASE_URL}${endpoint}`, { ...options, headers });
-  if (!response.ok) {
-    const errorBody = await response.json().catch(() => ({ detail: 'Network response error' }));
-    throw new Error(errorBody.detail || `HTTP Error ${response.status}`);
-  }
-  return response.json();
-}
-
-export async function startOnboarding(patient: PatientContext, category: CategoryContext, language: string = 'en') {
-  return fetchApi<any>('/v1/onboarding/start', {
-    method: 'POST',
-    body: JSON.stringify({ patient, category, language }),
-  }, patient.id);
-}
-
-export async function sendMessage(sessionId: string, patientId: string, message: string) {
-  return fetchApi<any>(`/v1/onboarding/${sessionId}/message`, {
-    method: 'POST',
-    body: JSON.stringify({ message }),
-  }, patientId);
-}
-
-export async function completeOnboarding(sessionId: string, patientId: string, confirmed: boolean = true) {
-  return fetchApi<any>(`/v1/onboarding/${sessionId}/complete`, {

-    body: JSON.stringify({ confirmed }),
-  }, patientId);
-}

-## 11. Frontend Integration Checklist
-
-```text
-[ ] Configure API_BASE_URL in environment (VITE_API_BASE_URL=http://localhost:8000)
-[ ] Verify CORS preflight request from localhost:3000 / localhost:5173
-[ ] Attach Authorization: Bearer test_token_<PATIENT_ID> header
-[ ] Call POST /v1/onboarding/start and store session_id
-[ ] Multi-turn chat message sending via POST /v1/onboarding/{session_id}/message
-[ ] Handle 401 Unauthorized & 403 Forbidden errors
-[ ] Upload medical documents via POST /v1/documents/{session_id}/upload (10MB max)
-[ ] Call POST /v1/onboarding/{session_id}/complete to retrieve final PatientOnboardingResult
-[ ] Test voice onboarding audio streaming via GET /v1/voice-onboarding/audio/{audio_id}
-```

-# Production Security & Compliance Checklist
-
-## 1. Authentication & Authorization Controls
- [x] **Bearer Token & API Key Authentication**: Verified (`app/core/security.py`).
- [x] **IDOR Session Ownership Validation**: Verified (`session.patient_id == auth.patient_id`).
- [x] **Unauthenticated Access Prevention**: Unauthenticated requests return `401 Unauthorized`.
- [x] **Unauthorized Session Modification Prevention**: Cross-patient requests return `403 Forbidden`.
-
-## 2. Input Validation & Schema Boundaries
- [x] **Numeric Age Validation Bounds**: Enforced `ge=0, le=120` in `PatientContext` schema (`422` returned on invalid inputs).
- [x] **String & XSS Sanitization**: HTML tags stripped/escaped from initial greetings.
- [x] **File Upload Restrictions**: 10MB size limit and strict MIME validation (`JPEG`, `PNG`, `WEBP`, `PDF`).
-
-## 3. Network & Transport Security
- [x] **CORS Configuration**: Wildcard origin (`*`) removed; explicit domain origins configured.
- [x] **HTTP Security Headers**: `X-Content-Type-Options: nosniff`, `X-Frame-Options: DENY`, `Referrer-Policy: strict-origin-when-cross-origin` attached.
- [x] **Rate Limiting**: IP-based rate limiting enforced on API endpoints (`429 Too Many Requests` returned with `Retry-After`).
-
-## 4. Operational & Container Security
- [x] **Non-Root Container**: Dockerfile configured with dedicated `appuser` (UID 999).
- [x] **Request ID Tracking**: Attached `X-Request-ID` correlation header to all HTTP requests.
- [x] **Error Masking**: Stack traces hidden behind generic `500 Internal Server Error` responses.
