# -*- coding: utf-8 -*-
"""
BiMISC-style coding pipeline (SEA-LION edition)

Implements:
- Prompt template: task instruction + role-specific MISC manual + 2 examples/code + brief history
- Deterministic decoding (temperature=0)
- Multi-label outputs with a confidence gate (threshold)
- Fine-grained codes + optional mapping to AnnoMI coarse codes
- Metrics: Accuracy, Precision, Recall, Macro-F1 (multi-label)
- Robust JSON-only output enforcement and retry/backoff for API stability

Environment (.env):
  SEA_LION_API_KEY=...               # required
  SEA_LION_BASE_URL=https://api.sea-lion.ai/v1   # optional (default)
  SEA_LION_MODEL=aisingapore/Gemma-SEA-LION-v4-27B-IT   # optional (default)

Expected input dataset (JSONL):
  Each line: {
    "history": [{"role":"Client","text":"..."}, {"role":"Therapist","text":"..."} ...],
    "utterance_role": "Therapist" | "Client",
    "utterance_text": "..."
    # optional gold annotations:
    # "gold_fine": ["OQ", "SR", ...],
    # "gold_coarse": ["QS", "RF", ...]
  }

Output:
  - Writes silver annotations into each item:
      "silver_fine": [...], "silver_coarse": [...]
  - Saves JSONL to `save_path`

# ----------------------------
# Notes:
# ----------------------------
# - This schema follows MISC 2.5 (Houck et al., 2010 update) exactly:contentReference[oaicite:2]{index=2}.
# - BiMISC simplifies some categories:
#     • ADV = ADP + ADW
#     • SP = SU
#     • STR = ST
#     • Drops CO, RCP, RCW, RF
# - If your target is AnnoMI (QS, RF, TI, NT, CT, ST), BiMISC mapping is sufficient.
# - If you want strict gold-standard MISC 2.5 coding, you must use this full set.
