-## OpenAI-Compatible Adapter
-
-`OpenAICompatibleClient` posts JSON to:
-
-```text
-<base_url>/chat/completions
-```
-
-It sends:
-
-- `model`
-- `messages`
-- `response_format.type = "json_schema"`
-- `response_format.json_schema.name`
-- `response_format.json_schema.strict = true`
-- `response_format.json_schema.schema`
-
-If an API key is configured, the adapter sends an `Authorization: Bearer ...`
-header.
-
-The adapter accepts assistant content either as a JSON string containing JSON or
-as raw JSON content. It then unmarshals that content into the caller-provided
-target.
-
-External wire-contract details belong in the
-[OpenAI-compatible integration doc](../integrations/openai-compatible.md).
-
-## Retries And Timeouts
-
-The adapter retries:
-
-- provider request failures;
-- response read failures;
-- HTTP `429`;
-- HTTP `5xx`;
-- malformed provider envelopes;
-- malformed assistant JSON;
-- structured-output decode failures.
-
-Non-retryable `4xx` responses are returned without retry. Context cancellation
-is respected.

 ## Scheduler
 
 `Scheduler` bounds concurrent provider calls. It tracks in-flight calls and a
