Evidence mode

Every decision becomes replayable evidence.

One inspection cycle leaves behind a sealed, ordered record — not a screenshot. Replay any unit by lot and SKU to see exactly what was measured, which packs decided it, and how it was routed.

Decision explanation

REJECT

This reject is not AI alone. HoldField combined what the model perceived, the measurement against the limit, coverage of every required region, the deterministic rule pack, station health at capture time, and the sealed evidence — then derived the outcome. AI finds signals. The rule pack decides. The record proves it.

Where the record earns its keep

One sealed record, many answers.

Customer complaint response

Pull the exact unit by lot and SKU, replay its decision and overlays, answer with proof instead of apology.

Supplier dispute

Show the measured value against the limit at the moment of inspection — a tamper-evident, dated record.

Internal audit

Walk the ordered event trail for any unit: who, what, when, and which rule and model packs decided it.

CAPA investigation

Trace a defect family across lots back to the first sealed receipt that caught it, with reason codes attached.

NPI transfer

Hand a new line the criteria, rule, and model packs that an existing station already proves out in evidence.

Model / rule governance

Every receipt names the exact packs that decided it, so a pack change is auditable, not invisible.

Lot trend analysis

Group sealed receipts by lot to see coverage, reject rate, and reason codes trend before they escape.

See it on your own line.

Map a first station and the same evidence layer scales from one inspection to factory-wide quality intelligence — every decision replayable, every record sealed.
