Manual checkpoints and verified external completion

These are separate escape hatches with different evidence requirements.

Complete a manual checkpoint

1. Open a ready manual node.
2. Read the checkpoint title and description.
3. Independently verify the stated offchain prerequisite.
4. Select Complete checkpoint and confirm.

Only an explicit manual node can be completed this way. The action is audited and unblocks only its graph dependents. It cannot manually pass a chain condition.

Record external completion

Use external completion when the required transaction happened outside txcast but can be proven onchain.

1. Open the transaction step.
2. Enter the transaction hash and a non-secret note.
3. Confirm the chain and expected execution account.
4. Submit for verification.

txcast verifies the transaction against the frozen required calldata, destination, value, and account before marking the step executed. A Safe completion additionally requires the matching Safe execution event.

Danger

Do not use external completion to declare that equivalent business work happened. The submitted transaction must match the frozen technical requirements. Conditions cannot be bypassed and variable values cannot be changed.

Failed verification

Check the chain, transaction hash, sender/Safe, receipt status, and confirmation depth. If the transaction was different, leave the run incomplete or cancel it; do not try to force a match.
