Pull request overview

This PR updates the generated OpenAPI reference artifacts to expose a new compute_units field in usage objects (Responses and Chat Completions) and refreshes Castiron generation metadata accordingly.

Changes:

• Add compute_units (nullable non-negative integer) to CompletionUsage, ResponseUsage, and BetaResponseUsage.
• Add two new tenant.trusted_access.* event strings to the relevant webhook/event enum list in the transformed spec.
• Update .castiron.stats.yml to reflect the new generation/spec hashes and codegen SHAs.

File	Description
api_reference/openapi.transformed.yml	Adds compute_units to usage schemas and introduces two new tenant trusted-access event identifiers.
.castiron.stats.yml	Updates Castiron generation metadata/hashes to match the regenerated OpenAPI artifacts.

• The description text is self-contradictory: it says compute_units is "null when available". This should read as null until it’s available (or null when unavailable) so API consumers aren’t misled.

Reviewed d6e48a06cdf7aee6a556758050303d04bdaa80fa. The three usage schemas consistently add an optional, nullable, non-negative integer, and the CLI's raw-response/RawJSON output paths preserve the new field without requiring response-model changes here. The two event-enum additions are additive. I also verified the transformed specification's MD5 matches the updated generation metadata.

No substantive issues or additional inline findings. The already-reported description wording nit is non-blocking and can be corrected in the authoritative schema.

[jbeckwith-oai]

Verified the schema-only update adds optional nullable nonnegative compute_units consistently to Responses and Chat usage without changing CLI runtime behavior or dependencies; generated metadata and canonical enum synchronization are consistent.
