# Aether Project Brief: aether_api_fastapi
**Last Updated:** 2026-01-28 19:21:44
**Current Agent:** mcp_agent

## 🛠️ What I Just Did
Implemented GET /v3/data_store/code/{code} with cascading lookup and limit override. Refactored Data_Store_Base for ID Vision standard. Created ARCH__V4_CORE_STANDARDS documentation. Updated and synced GUIDE__V3_FRONTEND_API. Fixed legacy data_store router crashes. Unified E2E testing for Data Store.

## 🚧 Current Blockers
None. System is stable at release baseline v3.0.99.

## ➡️ Exact Next Steps
1. Begin Aether API V4 lifecycle field migration (approved_on, enable_on, archive_on). 2. Standardize Search Optimization (default_qry_str) across all core objects. 3. Unify Websocket infrastructure.
