Planning Summary Audio Analyzer - Hugging Face Spaces App
Analyzes audio recordings of planning conversations and generates 
a structured Word document planning summary report using Google's Gemini API.
CHANGELOG (corrections applied):
  1. Treatment preference: added "conditional_comfort_care" option for nuanced cases
  2. Beneficiary status: improved prompt guidance to distinguish account access from
     formal beneficiary designation
  3. Values vs. care preferences: clarified prompt so medical decision criteria are not
     conflated with life meaning/joy
  4. Personal items: added "no_specific_items" option (deliberate choice vs. indecision)
  5. Name spelling: prompt now flags uncertain proper noun spellings with [verify spelling]
  6. Next Steps section: driven by extracted data and topics discussed, not hardcoded
  7. Prompt includes "topics_discussed" field so the report only covers relevant sections
  8. Resilience: retry logic (up to 3 attempts), robust JSON parser, raw response
     surfaced on failure for debugging
  9. Hallucination guard: prompt instructs model to return not_a_planning_conversation
     flag when audio does not contain advance care planning content; validation rejects
     such responses before generating a report.

# ============================================================================

EXTRACTION_PROMPT = """
You are analyzing a recorded conversation about advance care planning and end-of-life wishes.
Listen to the ENTIRE audio carefully and extract ALL relevant information.

IMPORTANT - NON-RELEVANT AUDIO DETECTION:
Before extracting any planning data, first determine whether this audio actually
contains an advance care planning conversation. The audio MUST contain a real
discussion about at least one of these topics: health care wishes, financial
planning, funeral/memorial preferences, or values and legacy.

If the audio is:
- Silence, noise, music, or unintelligible speech
- A conversation about unrelated topics (e.g. casual chat, a lecture, a podcast
  not about advance care planning)
- Too short or too unclear to extract meaningful planning information
- Random test audio or microphone checks

Then return ONLY this JSON and nothing else:
```json
{
  "not_a_planning_conversation": true,
  "reason": "Brief explanation of what the audio actually contains"
}
```

Do NOT invent, fabricate, or hallucinate planning data. If you cannot clearly hear
a real advance care planning discussion, you MUST return the above JSON.

Only proceed with the full extraction below if you are confident the audio contains
a genuine advance care planning conversation.

CRITICAL INSTRUCTIONS FOR SINGLE-SELECT FIELDS:
- You MUST select exactly ONE option for each single-select field
- Use the EXACT string values specified (copy them exactly)
- If the conversation implies something even indirectly, make your best inference
- NEVER leave single-select fields as null - always pick the best match
IMPORTANT RULES FOR PROPER NOUNS:
- If a last name is spelled out letter by letter, use that exact spelling.
- If a last name is only spoken (not spelled), transcribe it phonetically and append
  [verify spelling] after it. Example: "Potoff [verify spelling]"
- First names that are spelled out should use the spelled version.
Return a JSON object with this EXACT structure:
```json

DECISION GUIDE FOR COMMON SCENARIOS:
topics_discussed:
- Listen for which topics the participant chose to focus on
- Only include "health", "financial", and/or "funeral" if they were actually discussed
- If the participant said they only want to discuss health and financial, do NOT include "funeral"
advance_care_status:
- If they say they haven't done paperwork/documents yet -> "no_documents"
- If they have old documents that need updating -> "has_documents_needs_update"
- If they have current, up-to-date documents -> "has_current_documents"
treatment_preference:
- If they UNCONDITIONALLY want only comfort/palliative care, no machines ever -> "comfort_care_only"
- If they want full treatment/CPR/ventilation IF there's hope of meaningful recovery -> "full_treatment_if_recovery"
- If their preference DEPENDS ON CONDITIONS such as cognitive function, prognosis,
  or quality of life (e.g. "treat me if I can still think clearly, but let me go
  if I'm cognitively impaired") -> "conditional_comfort_care"
- If they're unsure or need more information -> "unsure"
beneficiary_status:
- IMPORTANT: "all_current" means the participant explicitly confirmed that formal
  beneficiary designations (not just account access) are filed and up to date
- If they say their trusted person "has access" or "knows about" the accounts but
  did NOT explicitly confirm legal beneficiary designations are current -> "unsure"
- If they know some designations need updating -> "need_to_update"
- If they're not sure who's listed or need to check -> "unsure"
has_info_list:
- If they have files/info but haven't shared the location or it's disorganized -> "yes_not_shared"
- If their trusted person knows where everything is -> "yes_shared"
- If they haven't created any list -> "not_created"
shared_with_loved_ones:
- If they've talked but nothing is written down -> "yes_not_written"
- If they've discussed AND written it down -> "yes_written"
- If they haven't discussed wishes yet -> "not_yet"
specific_items_status:
- If they named specific items for specific people -> "has_specific_items"
- If they explicitly said no specific designations are needed (e.g. "everything goes
  to my spouse" or "nothing specific needs to go anywhere specific") -> "no_specific_items"
- If they haven't thought about it yet or are undecided -> "not_yet_decided"
service_type / body_preference / cost_planning:
- If funeral planning was NOT discussed at all, use "not_discussed" for these fields
- Celebration of life, casual gathering, party -> "celebration_of_life"
- Traditional funeral -> "funeral"
- Memorial service -> "memorial"
- Cremation, ashes spread somewhere -> "cremation"
- Burial in cemetery/ground -> "burial"
- Donate body to science -> "donation"
- If they mention life insurance will cover it or family knows about funding -> "family_aware"
- If they have a pre-paid funeral plan -> "prepaid"
- If costs haven't been discussed -> "needs_discussion"
values_reflections:
- "meaning_and_joy": ONLY include hobbies, relationships, passions, and activities
  that bring happiness. Do NOT include medical decision criteria like cognitive
  function preferences here. Those belong in treatment_details.
- "want_remembered_for": Use the participant's own words about how they want to be remembered.
- "what_matters_most": Summarize their overall philosophy about living and legacy.
recommended_next_steps:
- Set each to true ONLY if it is relevant based on what was discussed
- For example, if funeral planning was not discussed, do not set explore_funeral_preplanning to true
- If documents already exist and are current, do not set create_healthcare_poa to true
- Base these on gaps identified during the conversation
Listen for these key topics:
- Who would make healthcare decisions (usually spouse first, then adult child)
- Who would handle finances (often same people)
- Whether they have existing legal documents
- Their wishes about medical treatment and life support
- Funeral/memorial preferences
- Special items to give specific people
- What matters most to them, their values
Return ONLY valid JSON, no markdown formatting or explanation.
