001 / CLOSED002 / IN WINDOW

A valid signature can accompany either outcome. The agreed time window decides the historical result.

02 / TASK BYTESCheck what arrivedExact agreed bytes

EXACT1 BYTE CHANGED

The published test changes one task byte. The receipt stays fixed, so the digest exposes the difference.

03 / RECEIPT SIGNATURECheck the receiptOriginal signature

ORIGINAL1 BYTE CHANGED

This test changes one signature byte. A timestamp that looks right still has to verify.

01 / For a human

The answer in words.

What was agreed: Verify a time-bound availability inquiry.; Agreed window: 2026-08-31 at 07:00:00.000 UTC to 2026-08-31 at 23:59:59.000 UTC.
When it was witnessed: 2026-08-31 at 07:13:37.433 UTC; Signed interval: 2026-08-31 at 07:13:27.433 UTC to 2026-08-31 at 07:13:47.433 UTC.
Whether it checks out: The signature and task bytes check out. The whole witness interval falls inside the agreed window. PROCEED at this recorded checkpoint.

Signature: checks outTask bytes: match

02 / For an agent

The answer in bytes.

PROCEED and STOP are the example consumer policy at the recorded checkpoint. These receipts are historical. They do not authorize a task now or prove that the task was carried out.

The receipt records that POPCORN witnessed a digest at its stated time. The stated time interval is signed, but its clock accuracy is not independently established here. Bundled historical public keys make these records reproducible; real use requires an independently trusted issuer key.

The current verifier requires the whole witness interval inside the saved task window. Crossing a boundary requires a recheck and stays STOP on this page. A changed task or failed signature also returns STOP. No wallet, payment, task execution, or data submission is started by the sliders.
