03 Field notes
Notes from the build.
- ↗
Why I moved Postgres to Render
Arkah needed fewer of Supabase's features, and moving the database to Render meant a fast internal network hop and one less dashboard.
- ↗
Writing a method people can inspect
Replacing Arkah's custom-framework form with an editable method page made the reasoning itself easier to review.
- ↗
A recommendation needs a way to be wrong
Strengthening Arkah's strategic reports meant allowing the evidence to change the recommendation and making unresolved objections visible.
