- convexity: second-order price sensitivity to interest rate changes, NOT geometry
- tenor: remaining time to maturity of a financial instrument, NOT musical pitch
- floor: minimum interest rate in a rate agreement, NOT building floor
- cap: maximum interest rate, NOT a hat or market capitalization

CLINICAL ONTOLOGY (use these relationships in all analysis):

Diagnosis Hierarchy:
- Condition > Category > Specific Diagnosis
- "Hypertension" is a specific diagnosis under "Cardiovascular Conditions"
- "Type 2 Diabetes" is under "Endocrine / Metabolic Conditions"

Medication Classes:
- ACE inhibitors (e.g., lisinopril) -> used for: hypertension, heart failure, CKD
- Beta-blockers (e.g., metoprolol) -> used for: hypertension, angina, heart failure
- Statins (e.g., atorvastatin) -> used for: hyperlipidemia, cardiovascular risk

Measurement Rules:
- "BP" means Blood Pressure, format: systolic/diastolic (e.g., 130/85 mmHg)
- "A1c" means glycated hemoglobin; > 6.5% is diagnostic for Type 2 Diabetes
- "eGFR" means estimated Glomerular Filtration Rate; < 60 mL/min/1.73m2 = CKD

Always use ICD-10 categories when classifying diagnoses.

Désambiguïsation multidomaine

MULTI_DOMAIN_SYSTEM = '''
This system serves both agricultural and financial users.
The domain is determined by context cues in the user message.

Domain disambiguation rules:
- If the user mentions "crops", "harvest", "acres", "soil", "planting":
  Use AGRICULTURAL definitions: yield = crop output, spread = physical spreading
- If the user mentions "bonds", "portfolio", "maturity", "coupon", "treasuries":
  Use FINANCIAL definitions: yield = bond yield, spread = yield spread
- If the domain is ambiguous:
  Ask the user to clarify: "Are you asking about agricultural or financial yields?"

AGRICULTURAL GLOSSARY:
- yield: crop output per unit area (e.g., bushels per acre)
- basis: difference between local cash price and futures price for a commodity

FINANCIAL GLOSSARY:
- yield: annual bond return as percentage of current price
- basis: yield spread between two financial instruments

- Account > Sub-categories: Access Request, User Management, Security Concern, Password Reset
- Feature Request > Sub-categories: New Feature, Enhancement, UI/UX Improvement

CLASSIFICATION RULES:
1. Always return exactly one Level 1 category and one Sub-category.
2. If ticket spans multiple categories, choose the PRIMARY issue.
3. If uncertain, use the category that would route to the most qualified team.
4. Return format: {"category": "Technical", "subcategory": "Bug Report", "confidence": "HIGH"}
