A witness in every pocket.

The labeling, and what it bought.

Then we taught it to read the strip.

Drawing vector spaces around test objects teaches a CNN what things are. For OralTox panels we went further — a separate model that reads what the colors mean, interpreting color-coded litmus strips through ordinary web cameras: uneven lighting, cheap optics, real homes.

The gate itself: YOLO evaluation on SageMaker.

Labels are only the start. A screen capture from the actual workflow — YOLO evaluation running on AWS SageMaker, scoring each candidate model against the held-out set before anything our floor labeled is allowed near production inference.

A test no one watches is a test no one trusts.

Court-ordered and recovery-program drug testing traditionally means travel, scheduling, and a human observer. RecoveryTrek's Proof platform replaces the trip with a phone — if the result can be trusted.

Punch built the verification layer: real-time inference confirms the right person is taking the right test the right way — flagging anything questionable for human review, with the evidence attached.
