Per Mike: import runs every 15 min, so routine timing isn't the cause. The 379
absent units are confined to 2025-10..2026-01 (stop after Jan 2026) on TS-4L/4R/1R
- fingerprint of a one-time overwrite during the incident/recovery (fresh DOS logs
overwrote accumulated appended server-side logs for ~2 weeks). One-time, not
recurring; backfill from the surviving staged .TXT.

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.
