Cursor model listing

Live catalog is exclusive when synced

After a successful Cursor model sync (cursor-agent --list-models → persisted synced catalog), the dashboard, /v1/models, and Test All list:

1. Models returned by the live sync
2. Injected auto-router ids: auto, auto-cost, auto-balance, auto-intelligence
3. Operator custom models (Import / manual) — never pruned by sync

The large static registry under open-sse/config/providers/registry/cursor/ is offline fallback only. When synced is empty (or discovery fails), listing falls back to that registry.

Effort-suffixed ids (for example claude-4.6-sonnet-high) may still be requested at runtime: resolveRequestedModel strips the suffix into a wire ModelParameter. Exclusive listing intentionally hides those static variants from Test All so probes match what Cursor actually returns as available.

Helpers

• providerUsesExclusiveSyncedListing("cursor"|"cu") — src/lib/providers/modelListingCapability.ts
• mergeProviderModelListing — dashboard merge
• ensureCursorAutoCatalogEntry — auto* inject on discovery + listing
• shouldSuppressStaticModelForExclusiveListing — /v1/models static loop
