+"""Reactive request-correction layer.
+
+When an upstream rejects a request with a recoverable 4xx error, this layer
+tries to *fix* the request body and let the caller retry the same upstream
+instead of failing outright. It is provider-agnostic: correctors key off the
+upstream's own error wording, so the same recovery works across every provider.
+
+The layer is a small pipeline of :data:`Corrector` callables. Each corrector
+inspects the parsed request body and the upstream error message and either
+returns a corrected body (plus a short label identifying the fix) or declines
+by returning ``None``. Adding a new reactive fix means writing one corrector
+and adding it to :data:`DEFAULT_CORRECTORS` — no changes to the proxy loop.
+
+All corrections are immutable: a corrector never mutates the body it is given,
+it returns a new ``dict``. The proxy threads an ``applied`` set of fix labels
+through retries so each distinct fix is applied at most once, guaranteeing the
+retry loop always terminates.

+providers' own streaming docs):

+  ``Unexpected token ':'`` client crash).
+* Gemini (native ``alt=sse``) - ``data:`` payloads framed with CRLF.

+The invariant every provider must satisfy: every line the proxy emits that
+starts with ``data: `` either equals ``[DONE]`` or is valid JSON, and no SSE
