+## Architectural changes require maintainer approval
+
+Never change software architecture, runtime config, or platform settings without discussing with the maintainer first. This includes — non-exhaustively — caching strategies (ISR, `unstable_cache`, `'use cache'`, module-level singletons, fetch caching), Suspense / streaming patterns, error-boundary placement, runtime exports (`runtime`, `revalidate`, `dynamic`), `vercel.json` cron schedules and `bunVersion`, `next.config.ts` flags. Present the evidence and the candidate change, then wait for direction. "Auto mode" does not include architectural decisions.
+
+## Claims about platform behavior need primary sources
+
+Any statement about how Next.js, Bun, Vercel, Neon, `@vercel/blob`, or other platform components behave must be backed by a primary source — official docs, the package's source / type definitions, an official changelog, or a reproducible local experiment. Pattern-matching on symptoms ("looks like a Bun bug") is not evidence. If you don't have a source, say "I don't know" instead of speculating.
+
+## Simplification means stripping to essence, not swapping complexity
+
+When asked to simplify, the correct move is to remove the smallest viable surface and prove the remainder works against real data. Removing one abstraction while introducing two new ones is not simplification.

 Ousterhout, Kernighan, Pike. Favor deep modules, simple interfaces, clarity over cleverness.
