Note that our staging environment is in the eu-west-1 region.
bare Bare model loop — no harness vs flagOn PersonalAssistant with the one-loop harness-driven proposerbare — controlflagOn — candidateUpdated — staging now runs in `us-east-1` (as of this morning's migration). The database is still Postgres 15. So the current staging facts are: - Region: `us-east-1` - Database: Postgres 15
Got it — updating the note: staging now runs in **us-east-1** (migration completed this morning), and the staging database is Postgres 15.

Understood — I'll assume the staging environment is in `eu-west-1` for any AWS operations, configuration, or troubleshooting we work on. Let me know what you'd like to do.
Got it — staging is on Postgres 15, in `eu-west-1`. I'll keep both in mind. What would you like to work on?

The harness runs on every turn. Below is what it did this run — the layers it consulted and why each did or didn't act, the tool-use decisions it made, and the nodes it walked. Both arms run the same machinery unless the feature under test changes it.
