## Summary
- Refactors the admin interface into focused views and simplifies the
header (removes noisy status labels; hides managed-source labels where
appropriate).
- Fixes Claude runtime settings handling, reduces Z.ai base URL leakage
in the admin UI, and streamlines API startup logging.
- Updates configuration and catalog behavior (including `.env.example` /
README), and expands automated tests around admin, app lifespan, and
config/registry behavior.
## Test plan
- [ ] `uv run ruff format`, `uv run ruff check`, `uv run ty check`, `uv
run pytest`
- [ ] Smoke the admin UI: navigation between views, settings save/load,
no sensitive URL leakage in the UI
- [ ] Confirm API startup logs are readable and not overly verbose in
normal operation
## Summary
- split the admin UI into Providers, Model Config, and Messaging views
- remove generated env, diagnostics, smoke, managed-label, and fixed
cloud/runtime settings from the visible admin UX
- make Z.ai base URL, Claude workspace, and Claude CLI binary fixed
app-level behavior instead of managed env fields
## Verification
- uv run ruff format
- uv run ruff check
- uv run ty check
- uv run pytest
- Default LOG_FILE to logs/server.log in settings and admin config
- Create log parent directories in configure_logging
- Gitignore /logs/, /server.*.log; keep server.log for root override
- Add test for nested log path mkdir
Generalize retryable_upstream_status to HTTP 500-599 plus 429.
Improve execute_with_retry log label with actual status.
Preserve OpenAI InternalServerError 5xx in map_error after overload check.
Unify native stream send: log via _raise_for_status then optional async aclose.
Add _maybe_await_aclose for httpx doubles in tests.
Rename openai compat retry tests to 5xx; parameterize native/limiter/mapping tests.
Extend execute_with_retry with retryable_upstream_status for 429/503
shared backoff, reactive block, and TRACE provider.retry.scheduled.
Map InternalServerError(503) to APIError with preserved status.
Native transport closes-and-raises on 503 like 429 for clean retries.
Add NIM/OpenAI-compat and rate limiter tests.
