Effect-TS

Apply Effect semantics using local project patterns first, then only the task-specific reference and upstream source needed to resolve uncertainty.

Fast Path

Do not activate this workflow merely because a file imports effect. For nontrivial Effect changes:

1. Inspect neighboring services, layers, errors, schemas, runtime boundaries, and tests.
2. Read references/critical-rules.md before editing. In particular, Effect failures are not caught by ordinary try/catch inside Effect.gen; avoid assertion-driven type escapes; use explicit terminating yields for error branches.
3. Read only the matching reference rows below.
4. Implement the least surprising pattern consistent with local code and verify the changed Effect behavior.
