Two new optional fields appear in per-model usage/pricing records:
canonicalModel: The canonical model ID used for the pricing lookup (e.g., claude-opus-4-7). May differ from the raw model string when provider-specific IDs or aliases are in use.
provider: The API provider that served the model: 'firstParty', 'bedrock', 'vertex', 'foundry', 'anthropicAws', 'anthropicGoogleCloud', 'mantle', 'gateway'.
These fields are useful for hooks and third-party cost tracking tools that need to normalize model identifiers across providers.
Evidence
New schema fields (search for "Canonical model id used for the pricing lookup")
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
