608 staged datasheets absent from DB. Two causes: (1) 229 units with encoded/
non-standard serials the importer's leading-digit regex silently skips - data is
in the .DAT, recoverable; full blind spot is 840 serials / 9,510 records / 141
models dropped fleet-wide. (2) 379 units whose per-model .DAT was overwritten by a
later work order - recoverable only from the staged .TXT or a log backup. Adds
John-facing report, raw data, and the chase-missing-units.js tool.

Whole-source sweep (981,716 records / 406,549 serials): 6,515 same-day multi-run
events; DB holds a NON-latest run for 311 (the strictly-greater-date conflict rule
freezes on an arbitrary same-day run). Corrects the verdict doc to flag same-day
retests as a latest-wins faithfulness violation (not benign). Adds the proposed
>= -with-data-differs conflict-rule fix (diagnose-only) and the sweep tool.

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).
