Validated all 11,922 staged original .TXT datasheets against test_records.
0 genuine parse faults across 11,239 comparable records; mismatches all explained
(retests, reused serials, VAS format, legacy out-of-scope units). Adds the
validate-parsing.js tool, raw report, and verdict. Two follow-ups (NOT parse bugs):
608 staged units absent from DB (ingestion completeness), and same-day retests keep
the first run (ON CONFLICT strictly-greater-date).
