Codex includes OpenAI tool_search in the tools array; omit it from the Anthropic payload like other passive hosted tools so fcc-codex requests do not fail at conversion.
## Summary
- Split monolithic `core/openai_responses/conversion.py` and `sse.py`
into focused protocol modules (input, output, stream, tools, reasoning,
events, etc.) behind an `OpenAIResponsesAdapter` facade.
- Wire `ClaudeProxyService.create_response()` through the adapter
instead of importing conversion helpers directly, tightening the
API/import boundary.
- Add Codex bridging for Responses `custom_tool_call` items and document
the adapter architecture in `ARCHITECTURE.md`.
## Test plan
- [x] `uv run pytest tests/core/openai_responses/
tests/api/test_openai_responses.py tests/cli/test_adapters.py
tests/contracts/test_import_boundaries.py`
- [x] Full CI via `.\scripts\ci.ps1`
## Summary
- Add `StreamRecoverySession` in
`core/anthropic/stream_recovery_session.py` to centralize early-retry
classification, holdback buffering, retry counting, and flush/discard
behavior shared by Anthropic and OpenAI transports.
- Refactor `AnthropicMessagesTransport` and `OpenAIChatTransport` to use
the shared session instead of duplicating recovery holdback and
early-retry logic.
- Update architecture docs and tests for per-delta overlap trim on
midstream recovery; bump version to 2.2.1.
## Test plan
- [x] `uv run pytest tests/core/anthropic/test_stream_recovery.py`
- [x] `uv run pytest tests/providers/test_anthropic_messages.py
tests/providers/test_streaming_errors.py`
Include copyable upstream status and error bodies in provider SSE failures for OpenAI-compatible and native Anthropic transports, while preserving retry behavior and safe logging defaults.
Update live smoke model defaults for NIM, OpenRouter, and Gemini; normalize tool-call indexes; downgrade DeepSeek forced tool_choice; and add coverage for the provider smoke fixes.
Route these providers through POST /messages with vendor headers and bases (including Kimi model list on OpenAI /v1/models). Remove Z.ai from OpenAI-chat server-tool rejection; extend tests and README.
## Summary
Adds support for the **OpenCode Go** subscription gateway at
`opencode.ai/zen/go/v1`, as requested in #504.
OpenCode Go exposes the same OpenAI-compatible Chat Completions API as
OpenCode Zen, so the implementation reuses `OpenCodeProvider` with a
configurable `provider_name` parameter — avoiding code duplication.
### Changes
- **Provider**: `OpenCodeProvider` now accepts `provider_name` (defaults
to `"OPENCODE"` for backward compatibility)
- **Catalog**: New `opencode_go` descriptor with correct base URL,
credential, and capabilities
- **Registry**: `_create_opencode_go` factory that passes
`provider_name="OPENCODE_GO"`
- **Settings**: `opencode_go_api_key` and `opencode_go_proxy` fields
- **Admin UI**: OpenCode Go API key, proxy, and smoke model config
fields
- **API services**: `opencode_go` added to OpenAI Chat Completions
upstream IDs
- **Smoke config**: Default smoke model `opencode_go/gpt-5.3-codex`
- **Tests**: New test for base URL, provider name, and API key; existing
tests updated
## Test plan
- [x] `test_opencode_go_provider_config_uses_correct_base_url_and_name`
— passes
- [x] `test_create_provider_instantiates_each_builtin` — covers
opencode_go
- [x]
`test_provider_and_platform_registries_include_advertised_builtins` —
covers opencode_go
- [x] `uv run ruff format`, `ruff check`, `ty check`, `pytest` — pass
locally on Python 3.14
Closes#504.

Registers FIREWORKS_API_KEY / FIREWORKS_PROXY in api/admin_config FIELDS so the UI can set credentials and provider status stays accurate.
Adds admin apply test and contract guards linking PROVIDER_CATALOG to FIELD_BY_KEY; updates .env.example.
## 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
