Luis Pater 6f923a28f7 feat(pluginhost): implement host authentication callbacks and add tests
- Introduced `auth_callbacks` for handling host authentication list, get, runtime, and save operations.
- Added extensive unit tests to validate functionality, including disk fallback and runtime-specific cases.
- Created example implementation in Go to demonstrate host callback integrations.

# Standard Dynamic Library Plugin Examples
This directory contains standard dynamic library plugin examples for the CLIProxyAPI C ABI.
## Layout
- `simple/`- : Go-only plugin resource that calls host auth file callbacks (, , , ).
- : full provider-native skeleton that declares every supported capability.
- `model/`: model capability only.
- `auth/`: auth provider capability only.
- `frontend-auth/`: frontend auth provider capability only.
- `frontend-auth-exclusive/`: frontend auth provider that becomes the only request authentication provider when selected.
- `executor/`: executor capability only.
- `protocol-format/`: minimal executor focused on input/output format declarations.
- `request-translator/`: request translation capability only.
- `request-normalizer/`: request normalization capability only.
- `codex-service-tier/`: Go-only request normalizer that sets Codex `gpt-5.5` requests to the priority service tier when enabled.
- `scheduler/`: Go-only scheduler that can select a configured auth ID, delegate to a built-in scheduler, or deny picks.
- `response-translator/`: response translation capability only.
- `response-normalizer/`: response normalization capability only.
- `thinking/`: thinking applier capability only.
- `usage/`: usage observer capability only.
- `cli/`: command-line capability only.
- `management-api/`: Management API and resource capability only.
- `host-callback/`: minimal plugin resource that demonstrates host callbacks.
- `host-callback-auth-files/`: Go-only plugin resource that calls host auth file callbacks.
- `host-model-callback/`: Go-only plugin resource that calls the host model execution callbacks.
Most standard capability examples contain `go/`, `c/`, and `rust/` subdirectories. Specialized examples may provide only the implementation language they need.
## Codex Service Tier
`codex-service-tier` declares the request normalization capability. When `fast` is `true`, it sets `service_tier` to `priority` for requests where `req.ToFormat` is `codex` and `req.Model` is `gpt-5.5`.
```yaml
plugins:
configs:
codex-service-tier:
enabled: true
priority: 1
fast: false
```
## Host Auth Files Callback
`host-callback-auth-files` declares the Management API capability and exposes a browser resource named `Host Auth Files`. The resource demonstrates `host.auth.list`, `host.auth.get` (physical JSON file), `host.auth.get_runtime`, and `host.auth.save`.
```yaml
plugins:
configs:
host-callback-auth-files:
enabled: true
priority: 1
```
See `host-callback-auth-files/README.md` for URL examples.
## Host Model Callback
`host-model-callback` declares the Management API capability and exposes a browser resource named `Host Model Callback`. The resource calls `host.model.execute` for non-streaming requests and `host.model.execute_stream` plus `host.model.stream_read` for streaming requests. It demonstrates explicit stream close with `host.model.stream_close` and an `implicit_close=true` option for RPC-scope host cleanup.
When the resource forwards its `host_callback_id`, CPA identifies the plugin that initiated the host model callback and skips that same plugin's interceptors for the nested execution. This makes host model callbacks non-recursive for the caller while allowing other plugins to intercept the nested request.
```yaml
plugins:
configs:
host-model-callback:
enabled: true
priority: 1
```
The default example model is `gpt-5.5`, but the request succeeds only when the current CPA model and auth configuration can route that model.
## Scheduler
`scheduler` declares the scheduler capability. It can select a configured auth ID from the candidate list, delegate to the built-in `fill-first` or `round-robin` scheduler, or reject picks when `deny` is `true`.
```yaml
plugins:
configs:
scheduler:
enabled: true
priority: 1
auth_id: ""
delegate: ""
deny: false
```
`auth_id` selects a matching candidate when `delegate` is empty. `delegate` accepts `""`, `fill-first`, or `round-robin`; other non-empty values leave the pick unhandled. `deny` returns a scheduler error.
## Build All Examples
```bash
make -C examples/plugin list
make -C examples/plugin build
```
Artifacts are written to `examples/plugin/bin`.
## Notes
`protocol-format` uses a minimal executor because format declarations belong to executor capabilities.
`host-callback` uses a minimal plugin resource because host callbacks are invoked from plugin methods and are not standalone capabilities.
Menu resources returned by `management.register` through the `resources` field are exposed by CPA under `/v0/resource/plugins/<pluginID>/...`. Authenticated plugin Management API routes remain under `/v0/management/...`.
