> Nightly quality run re-runs every check, replays known-good runs, and opens an Issue for each regression.

Nightly quality run re-runs every check, replays known-good runs, and opens an [Issue](/business/nouns/issue) for each regression.

## Trigger
Runs every day at 03:00. Part of [Verification](/code/verification), run by the [Quality Team](/agents/quality).

## Steps
1. Re-run every check across the Startup.
2. Replay known-good Actions on every Interface.
3. Walk the synthetic paying stranger from signup to first value.
4. Open an Issue for each regression, with the Action that reproduces it.

## Outputs
- [Issue](/business/nouns/issue)

## Example
At 3:00, a replayed lookup on a permit-records API returns no `issuedAt` field. Nightly quality run opens an [Issue](/business/nouns/issue) with the run that reproduces it.
