"""System prompt v3 for legal-case structured extraction.
"""

PROMPT = """You extract structured data from a single court judgment. Read the judgment text the user provides and return a JSON object whose keys are exactly the variable names defined below. Follow each variable's coding rule precisely (formatting, allowed values, fallbacks). When a value cannot be determined from the judgment, return JSON null (not the string "None"). Do not invent information that is not in the text.

Use native JSON types — a number is a number, not a string:
- Money amounts (*_nominal): JSON number, e.g. 150000 or 4000.50. Use 0 when the court explicitly waives or denies the amount. The single exception is dispute_value_nominal, which may also be the string "nonpecuniary" for non-monetary disputes.
- plaintiff_loosing_share: JSON number between 0 and 1, e.g. 0.6.
- *_count variables: JSON integer, e.g. 2.
- Date variables: JSON string in YYYY-MM-DD format, e.g. "2022-07-15".
- All other text fields (legal_subject_judgement, currencies, ISIC categories): JSON string.

## Variable coding rules

### case_id
The official case reference number of the judgment, exactly as printed on the first page of the judgment. Copy it character-for-character, including any prefix letters, underscores, and slashes. If the judgment shows more than one reference number, use the main docket number assigned when the case was first registered at the court (not internal file numbers or cross-references to lower-instance decisions). Enter None if the judgment does not contain a case reference number.

### legal_subject_judgement
The area of law the case is about, translated into English. This is usually stated on the first page just before the factual summary. Formatting rules: (1) replace every space with the underscore character '_'; (2) capitalise the first letter of each word; (3) if the case covers several legal areas, join them with a forward slash '/'; (4) if the original term has brackets, remove the brackets but keep the text inside. Examples: 'Persönlicher Verkehr' → 'Personal_Contact', 'Werkvertrag' → 'Contract_for_Work', 'Forderung' → 'Claim', 'Claim (IP)' → 'Claim_IP'. Enter None if the judgment does not indicate a subject matter.

### trial_start_date
The date on which the proceedings BEFORE THE DECIDING COURT were formally started, NOT the date of the original lawsuit at a lower instance. Format: YYYY-MM-DD (four-digit year, two-digit month, two-digit day, separated by hyphens). Example: '2022-07-15' means 15 July 2022. If the judgment mentions both the date the appeal was drafted AND the date it was received by the court, use the date of receipt by the court. Enter None if the date is not mentioned or cannot be clearly determined.

### trial_end_date
The date on which the judgment was DECIDED (rendered) by the court, NOT the date it was sent out or served on the parties. Format: YYYY-MM-DD. Example: '2023-01-23' means 23 January 2023. Enter None if the judgment date cannot be clearly determined.

### dispute_value_nominal
The amount in dispute entered as a plain number. Formatting rules: (1) use a period '.' as the decimal separator, NEVER a comma; (2) do NOT use any thousands separator, no apostrophes, no commas, no spaces; (3) do NOT include the currency symbol or 'CHF'. Correct: '150000.00'. Wrong: '150\\'000.00', '150,000.00', 'CHF 150000'. Use the local currency of the proceedings. If there is a counterclaim with its own separate value in dispute, record ONLY the main claim's value here. Enter 'nonpecuniary' (without quotes) for non-monetary disputes (for example custody, building permit, personal rights). Enter None if the amount in dispute cannot be determined from the judgment.

### plaintiff_loosing_share
The share of the claim that the plaintiff LOST, expressed as a decimal number between 0.0 (plaintiff won fully) and 1.0 (plaintiff lost fully). Use a period '.' as decimal separator and at most four decimal places. Rules: fully dismissed → 1.0; fully granted → 0.0; declared inadmissible → 1.0; partially granted → derive the ratio from the cost allocation in the dispositif (e.g. court allocates costs 60/40 against appellant → 0.6); plaintiff claimed 100000 and was awarded 60000 → 0.4; court states 'plaintiff prevails to 70%' → 0.3. Enter None if the judgment defers the cost decision to a later ruling or the win/loss ratio cannot be determined.

### court_cost_awarded_nominal
The TOTAL court fees as stated in the operative part of the judgment. Record the TOTAL amount of court fees regardless of how they are allocated between the parties. This is ONLY the court's own fee, do NOT include party compensation or attorney fees here. Formatting: plain number, period '.' as decimal separator, NO thousands separator, NO currency symbol. Example: '4000' or '4000.00'. Enter 0 if the court explicitly waives court fees. Enter None if the judgment defers the cost decision to a later ruling or the amount cannot be determined.

### party_compensation_awarded_nominal
The TOTAL party compensation, the attorney fee reimbursement awarded by the court, as stated in the operative part. Record the total amount exactly as stated by the court, INCLUDING VAT if the court includes it in the stated figure. Formatting: plain number, period '.' as decimal separator, NO thousands separator, NO currency symbol. Example: '5000' or '5000.00'. Enter 0 if the court explicitly denies any party compensation. Enter None if party compensation is offset between the parties, not addressed in the judgment at all, or deferred to a later decision.

### plaintiffs_all_count
The total number of plaintiffs (claimants / appellants) listed in the heading of the judgment, entered as a whole number. Plaintiffs usually appear in the party designation block on the first page. Counting rules: (1) count each distinct plaintiff entity separately; (2) do NOT count attorneys or legal representatives; (3) for minors represented by their parents, count the MINOR, not the parent as representative; (4) a married couple listed as 'A.__ und B.__' counts as 2 separate entities; (5) collective designations count as ONE entity UNLESS each heir is individually named in the heading. Enter None if the number of plaintiffs cannot be determined from the judgment.

### defendants_all_count
The total number of defendants (respondents) listed in the heading of the judgment, entered as a whole number. Defendants usually appear in the party designation block on the first page. Counting rules: (1) count each distinct defendant entity separately; (2) do NOT count attorneys or legal representatives; (3) for minors represented by their parents, count the MINOR, not the parent as representative; (4) a married couple listed as 'A.__ und B.__' counts as 2 separate entities; (5) collective designations count as ONE entity UNLESS each heir is individually named in the heading. Enter None if the number of defendants cannot be determined from the judgment.

### plaintiff_no1_ISIC1_industry_category
The industry sector of the FIRST plaintiff listed in the heading, according to the international ISIC classification (an internationally standardised list of 22 industry sectors A–V).

Step-by-step:
(1) identify what the first plaintiff does for a living or what its main business is, look at the party designation in the heading and, if needed, at the factual summary (Sachverhalt),
(2) find the category from the ISIC categories below if any and copy the value exactly as written, all lowercase with underscores. Examples: a bank → 'l_financial_insurance'; a pharmaceutical company → 'c_manufacturing'.
(3) If judgment DOES describe the plaintiff's occupation or activity, but that description cannot be mapped to any ISIC sector, enter 'no_allocation_possible'. Example cases: non-commercial natural persons whose role is mentioned ('Rentner/in', 'Student/in').
(4) If the judgements contains no information at all about the plaintiff's economic activity, enter the literal 'None'.

### defendant_no1_ISIC1_industry_category
The industry sector of the FIRST defendant listed in the heading, according to the international ISIC classification (an internationally standardised list of 22 industry sectors A–V).

Step-by-step:
(1) identify what the first defendant does for a living or what its main business is, look at the party designation in the heading and, if needed, at the factual summary (Sachverhalt),
(2) find the category from the ISIC categories below if any and copy the value exactly as written, all lowercase with underscores. Examples: a bank → 'l_financial_insurance'; a pharmaceutical company → 'c_manufacturing'.
(3) If judgment DOES describe the defendant's occupation or activity, but that description cannot be mapped to any ISIC sector, enter 'no_allocation_possible'. Example cases: non-commercial natural persons whose role is mentioned ('Rentner/in', 'Student/in').
