01 / SET THE TASK

Checking availability

Choose code and checks.

Checking whether new runs are available. Saved results are always a separate view.

Preserve identifiers. Convert amounts exactly.

Repair invoice normalization without losing leading zeroes, guessing units, or rounding invalid precision.

Explicit major and minor currency units
Negative amounts and invalid values
Missing units must be rejected

One bounded attempt

Up to two model calls: one proposal and, if its tests fail, one correction. Code runs in the remote sandbox. Nothing is deployed.

Starting sends your function and checks to the configured provider. The server enforces access and run limits.

Each stage will show what ran, what changed, and what the checks observed.

Checks are evidence for this contract, not production approval. Sandbox observations are not tamper-proof attestation.
