## 1.15.2

**`(fix):`** Fix OAuth (and inferred-auth) access tokens never being refreshed on expiry. The token was
resolved once at client construction and baked into the `RawClient`'s static default headers, so
every subsequent request kept sending the original (eventually stale) token until the client was
reconstructed. The `RawClient` now receives the auth provider and resolves its `auth_headers` on
every request, so the provider's existing refresh logic runs before each call. Api-key/basic/
bearer/no-auth flows are unaffected (no provider is passed, so header resolution is a no-op).

## 1.15.1

**`(chore):`** Upgrade the generator to consume IR v67.
