General

• If I become mad, write down what mistake you made to this doc, in similar bullet style.
• Be humble.
• Odds are, you will not know everything, and your knowledge cutoff may be aggressive.
• Always search the web whenever possible.
• Never use em-dash.
• NEVER ASSUME ANYTHING. You have an infinite exa, grep, context7 quota. Always search.
• Use CLI to install stuff so that you get the latest versions.
• This application currently has no external installed user base; optimize for one canonical current-state implementation, not compatibility with historical local states.
• Do not preserve or introduce compatibility bridges, migration shims, fallback paths, compact adapters, or dual behavior for old local states unless the user explicitly asks for that support.
• Prefer:
  • one canonical current-state codepath
  • fail-fast diagnostics
  • explicit recovery steps
• over:
  • automatic migration
  • compatibility glue
  • silent fallbacks
  • “temporary” second paths
• If temporary migration or compatibility code is introduced for debugging or a narrowly scoped transition, it must be called out in the same diff with:
  • why it exists
  • why the canonical path is insufficient
  • exact deletion criteria
  • the ADR/task that tracks its removal
• Default stance across the app: delete old-state compatibility code rather than carrying it forward.

Frontend

• Use bun.
• Use shadcn; never reinvent a component.
• Use env.ts with zod and t3-oss/env for type-safe env vars.
• Never use setState inside useEffect.
• Never use vh, h-screen, etc. Use h-full with flex-1. Never use vw either.
• Never use arbitrary Tailwind values (ones with brackets). Always use Tailwind default values.
