Best Engineering Practice

Produce correct software through explicit failure, simple ownership, unified boundaries, and reproducible evidence. Apply repository conventions unless they conflict with the Core.

Load Only Applicable References

Read references/core.md for every task.

Load architecture guidance only for affected runtimes:

• Read references/architecture/backend.md for services, handlers, workers, scheduled jobs, CLI processes, persistence, messaging, external integrations, or backend dependency direction.
• Read references/architecture/frontend.md for browser modules, UI, navigation, forms, design systems, client state, accessibility, browser security, or client performance.
