The sequencer feed is immutable in each implementation. Resolve and verify that immutable rather than assuming the network name alone selects the correct feed. Token feeds, stale periods, direct overrides, ownership, and ACM permissions are still dynamic proxy configuration.

This contract inherits the complete ChainlinkOracle API, including initialize, NATIVE_TOKEN_ADDR, prices, tokenConfigs, setDirectPrice, setTokenConfig, setTokenConfigs, owner, pendingOwner, transferOwnership, acceptOwnership, renounceOwnership, accessControlManager, and setAccessControlManager. Its override adds the one-hour sequencer recovery grace-period check before returning a price.
