 Python state Rust needs but does not own, behind one module per question. Rust imports a module here by path and calls a function by name
 
-- One module answers one question: `model_capabilities` (what a model can do), `callbacks_legacy_python` (the legacy callback registries), `settings` (configured snapshots), `cache` (the live configured cache), `diagnostics` (legacy failure logging), `secret_manager` (the configured secret manager and native config capture), `http_transport` (which async transport is in use), `timeouts` (timeout to seconds), `redis_events` (reporting native Redis calls and breaker transitions to `ServiceLogging`)
+- One module answers one question: `model_capabilities` (what a model can do), `callbacks_legacy_python` (the legacy callback registries), `settings` (configured snapshots), `cache` (the live configured cache), `diagnostics` (legacy failure logging), `secret_manager` (the configured secret manager and native config capture), `http_transport` (which async transport is in use), `timeouts` (timeout to seconds), `redis_events` (reporting native Redis calls and breaker transitions to `ServiceLogging`), `redis_credentials` (what a caller's redis-py `CredentialProvider` authenticates with)
 - A module is the only place Rust reads that Python state. Rust never does `py.import("litellm").getattr(...)` on a global; it asks here
 - Each module reuses the Python implementation the Python route runs (`AnthropicModelInfo`, `Logging`). Do not re-derive those rules here or in Rust; one resolver, two callers
 - The module path and function signature are a contract. The Rust side pins the path in a `const MODULE` in the crate that asks (`python-bridge/src/routes/messages/host.rs`, `python-bridge/src/secrets/`, `callbacks-legacy-python/src/python.rs`); change both sides together and keep `tests/unit/rust_bridge/host/` green
