📝 SummarySummary by CodeRabbit
WalkthroughThe change adds ACP model discovery for in-memory, Cursor, and macrod harnesses. It introduces shared model projection, subprocess probing, correlated runtime messages, authenticated model-loading APIs, and provider adapters. Pairing records now persist discovered catalogs. Settings screens load models per harness and render loading, error, unsupported, and unavailable states. OpenAPI specifications and documentation describe the new contracts. Merge Risk: 🟡 Moderate · up to Model discovery can exhaust worker resources, leave Cursor requests hanging, or prevent harness pairing when discovery fails. These material reliability issues should be fixed before merge. 🚥 Pre-merge checks | ✅ 4✅ Passed checks (4 passed)

entry in data.models; otherwise select data.models[0]?.id or the existing empty

- Around line 14-17: Update the OpenAPI definition for operationId
load_agent_models_handler to declare the authentication scheme used by
agentHarnessServiceClient and fetchWithToken. Add the applicable
components.securitySchemes entry and reference it in the POST /agent-models/load
operation’s security configuration, preserving the existing 401 response.
In `@crates/agent_harness/src/domain/model_load.rs`:
- Line 207: Update AgentModelsServiceImpl::load so the ModelHarness::Cursor
branch wraps self.cursor.probe(&caller) with tokio::time::timeout using
self.timeout, mapping expiration to LoadAgentModelsError::Timeout so the handler
returns 504.

- Around line 51-55: Update PairingClient::start so discover_model_catalog
failures are logged and treated as an absent catalog instead of being
propagated. Preserve successful discovery by passing Some(model_catalog), but
continue sending the pairing request with model_catalog: None for timeout,

Validate currentModel against models.
If a provider returns a currentModel that is absent from models, AgentModels::from_options preserves it, and preferredModelId selects it. The <select> then has no matching option, while submit still sends that id. Select a returned model id when the current model is unavailable, or add an unavailable option, and test this case.

Wrap the Cursor probe in the service timeout.
AgentModelsServiceImpl::load applies self.timeout only to MacrodModelProbe::probe; the Cursor branch directly awaits CursorModels::probe. CursorClient sets only connect_timeout(10s), so a connected /v1/models request can remain pending beyond the configured 10-second deadline. Wrap the Cursor probe with tokio::time::timeout and map expiry to LoadAgentModelsError::Timeout so the handler returns 504.

Do not block pairing on model discovery failures.
PairingClient::start propagates every probe_subprocess error before sending the pairing request. This can prevent pairing on a timeout, process failure, unsupported working directory, or protocol failure. CreatePairingRequest.model_catalog is optional, so log the error and continue with model_catalog: None.
