Read ATE and AOI results with the measurement uncertainty they carry, group defects and surface drift against the limits your engineers set, and assemble the pack for the named quality engineer, who decides.
Near-limit measurements are the slice an aggregate buries — a small share of readings, most of the amendments. Nestack reports the amendment rate by slice, not only in total.

Evidence-linked improvement
A cycle ends in a case, not a conclusion
Nothing closes on a review meeting. It closes on a case the next release has to pass, and that suite is what the next lot dispositioned is measured against.
Improvement cycle · five stagesSwitchback — the path turns at Improve and returns at Learn
01Detect
Amendment rate rises in a reading slice.
02Diagnose
If the reading and the log disagree, the trail is followed until one limit set, station or prompt accounts for it.
03Improve
Every change ships against a version with the lots attached.
04Verify
The release is blocked while an affected case fails.
05Learn
The case becomes permanent, and the disposition rules are re-tested.
Learn → DetectThe return edge. The suite the next lot meets is one case longer.
Typical build scope
Twelve workstreams across six weeks
The build scope read against the delivery timeline. Week structure follows the six-week plan — discovery, sources, reporting workflow, evaluation, integration, then production validation and handover.

Build a test agent around your limits and your quality engineers.
Show us a week of test logs and the limits behind them. You bring the decision rule, the acceptance criteria and the engineer who dispositions a lot. We map the reporting workflow around them.
