# Stage 05: Bootstrap and Dependency Assembly

Date: 2026-07-29

## Result

- Environment and legacy LLM credential resolution moved to `backend/bootstrap/settings.py`.
- Encryption-key initialization remains behavior-compatible and server-side.
- Stable service construction moved to `backend/bootstrap/container.py`.
- `DashboardService` keeps its compatibility attributes but receives them from one application
  container.
- The iFinD client is instantiated once and shared by chart services.
- HTTP routes, API payloads, background thread timing, database paths, and frontend assets are
  unchanged.

## Transitional Boundary

Some methods still construct Tushare clients directly. Stage 06 introduces `DataGateway` and
migrates those provider creation paths without combining that work with bootstrap changes.

## Rollback

Reverting this stage restores inline service construction. No database or configuration
migration is required.
