Check who measured, calibrated, and acted.
The fixture binds a registered instrument signature to a separately signed calibration record, then checks a scoped technician delegation and holder proof.
signed field evidence · public reference runner
A reading is not the decision.
Aadya checks whether submitted inspection evidence is signed, calibrated, authorised, fresh, scoped to the requested work, sufficiently complete, and unused before returning a policy decision and a minimised signed receipt.
what the endpoint exercises
Evidence first. Decision second.
The demo returns pass, fail, and insufficient-evidence cases so a policy rejection is not confused with missing or untrustworthy evidence.
Bind the evidence to this work.
Asset and work-order commitments, challenge nonce, freshness, sampling coverage, and one-time use are evaluated before the policy result is issued.
Return checks and commitments, not telemetry.
The signed result carries the decision and integrity checks while raw synthetic readings remain inside the fixture.

Run four expected outcomes.
The endpoint creates fresh synthetic fixtures and checks a valid batch, an out-of-policy measurement, insufficient sampling coverage, and a replay. It then verifies that a changed receipt field and a receipt re-signed by another key are both rejected.

Boundary returned by the endpoint
what a valid signature cannot prove
Integrity after capture is not truth before capture.
- No hardware-attestation claim. Local test keys represent registered parties; they do not prove a secure element or certified measuring device.
- No anti-tamper or physical-world-truth claim. A valid signature can protect submitted bytes without proving that a sensor was mounted correctly or that the observed event happened as asserted.
- No certified-calibration claim. The demo verifies a separately signed synthetic calibration record; it is not a calibration-laboratory accreditation.
- No regulated approval or workflow release. The receipt has no legal effect and does not replace an inspector, operator, regulator, or authorised partner system.
