Techstack

Global rules

• Effect is the TS domain/IO backbone — structured errors, DI, resource safety, retries — not ad hoc Promises
• One primary server stack per service
• Repo conventions beat greenfield defaults when they conflict
• Typed boundaries at every seam — decode/validate at runtime on untrusted input
• Greenfield installs: seven-day minimum registry release age — see domains/security.md
• TS relative imports (all apps, packages, routes, components): always extensionless — from './module', never from './module.js' or from './module.ts'
• Effect implementation depth in Effect repos → effect-ts skill
