 ## [Unreleased]
 
-### Breaking Changes
+### Changed
 
 - Changed `ApiKeyCredential` to use the `auth.json`-compatible discriminator `type: "api_key"` and provider-scoped `env` values instead of `type: "api-key"` and metadata.
 
 ### Fixed
 
+- Fixed Anthropic-compatible custom models to use explicit compatibility metadata instead of provider-name heuristics for session-affinity headers and unsupported tool-field omissions.
 - Fixed request-scoped `apiKey` and `env` values to participate in provider auth resolution, so providers such as Cloudflare can derive request-specific base URLs from explicit call options ([#6021](https://github.com/earendil-works/pi/issues/6021)).
 - Restored temporary legacy per-API stream aliases such as `streamSimpleOpenAICompletions` on the compat entrypoint ([#6016](https://github.com/earendil-works/pi/issues/6016), [#6017](https://github.com/earendil-works/pi/issues/6017)).
 - Restored runtime `detectCompat` fallback in `openai-completions` for models without explicit compat metadata ([#6020](https://github.com/earendil-works/pi/issues/6020)).
