effect-development

Use the repository's AI documentation as targeted reference, not ambient context: 1. Identify the Effect APIs and concepts involved in the change. 2. Search `LLMS.md` and `ai-docs/src` for those names and concepts, then read the matching sections and examples. 3. Apply the relevant guidance and inspect nearby source and tests for any repository-internal conventions not covered by the documentation. The task is ready for implementation when every material Effect API or pattern has matching local guidance, or the search has established that none exists.
