score.mjs

#!/usr/bin/env node
// Perch trap set scorer. No dependencies.
//
// Usage:
//   node score.mjs outputs.jsonl            summary table (totals + per clip counts)
//   node score.mjs outputs.jsonl -v          adds a miss / false-offer list per clip
//
// Input: corpus.jsonl (shipped with this repo) and an outputs.jsonl you produce by running
// your product on clips/*.wav. One line per clip:
//   {"id": "f001", "transcript": "<raw transcript or note text your product produced>",
//    "charted": ["Apoquel", "oclacitinib"]}
// "transcript" is optional (leave "" if your product only exposes a final chart/note).
// "charted" is the list of medication names that ended up in the chart/plan, exactly as your
// product wrote them.
//
// Scoring rules (see README.md "How scoring works" for the long version):
//   FOUND    a truth drug is credited if it appears, correctly spelled (normalized substring
//            match), in "transcript" OR in "charted". INN spelling variants are credited
//            (see ALIASES below; the table is small on purpose -- extend it if your product
//            uses a variant spelling not listed here).
//   MISSED   a truth drug not found either place.
//   FALSE OFFER   a charted term that is not a truth drug for that clip, is not a normalized
//            substring of the clip's own dictation text (so a drug genuinely said in the
//            dictation, even one off this benchmark's 66-name formulary, is never a false
//            offer), and is not the brand/generic partner (DRUG_PAIRS) of a drug that IS a
//            truth item on that clip. Everything else charted that isn't one of those three
//            things is counted as a false offer: a drug-like name in the chart nobody said.
//
// This mirrors the scoring rules used to produce the counts in RESULTS.md and ledger.md, so
// you can reproduce this repo's own numbers by running it against a re-derived outputs file
// for the two products already in ledger.md, or run it against any product of your own.
