Write 'meta:providers_meta' to Redis during provider synchronization,
including version, timestamp, and configuration checksum. This aligns
provider sync with model metadata handling and enables better cache
invalidation.
Restructure the provider management system by separating the monolithic
Provider model into two distinct entities:
- ProviderGroup: defines shared upstream configuration (type, base_url,
google settings, models, status)
- APIKey: represents individual credentials within a group (api_key,
weight, status, auto_ban, ban settings)
This change also updates:
- Binding model to reference GroupID instead of RouteGroup string
- All CRUD handlers for the new provider-group and api-key endpoints
- Sync service to rebuild provider snapshots from joined tables
- Model registry to aggregate capabilities across group/key pairs
- Access handler to validate namespace existence and subset constraints
- Migration importer to handle the new schema structure
- All related tests to use the new model relationships
BREAKING CHANGE: Provider API endpoints replaced with /provider-groups
and /api-keys endpoints; Binding.RouteGroup replaced with Binding.GroupID
- Update TESTING.md to reflect current testing status and future plans
- Add golden file comparison for provider snapshot validation in sync_test.go
- Introduce master_test.go for testing Master/Key functionality
- Add testdata directory for contract testing snapshots
