User, 17 Oct 2026: research on the inline QC equipment, which devices
can be used for the optical check.
- New docs/equipment/inline-optical-qc.md: defect-by-defect table with
the optical signature, device and limit (IEC 98 / DIN 45547 hole and
eccentricity, Stamper Discs targets, Mobineko warp limits), precedents
(no vinyl product; Dr. Schenk ISM CD scanner as template; Basler/Xiris;
PRP AQA 2023; CTU thesis), a station design (centring turntable, 4k
line-scan per side with dark-field, bright-field and transmitted light,
colour label camera, two laser warp sensors or a line profiler,
optional thermal camera) with sourced price signals, resolution and
eccentricity math, throughput, placement at the Duplex cell and the
Classic, smart-camera vs open GenICam/Aravis/OpenCV/anomalib on NixOS,
specials, Thai channels, next steps.
- Estimate USD 12k-30k hardware per station, ~USD 40k-100k for the two
launch stations; inside the existing metrology launch tier, no plan
price change.

integration row, README bullet and tree.
