- remove bytes_rules from _RuleFeatureIndex; bytes_prefix_index is the
only structure needed for candidate selection
- build bytes_prefix_index directly in _index_rules_by_feature() instead
of building bytes_rules then converting, removing one full pass
- add if -1 in bytes_prefix_index guard to avoid temporary object
creation for the short-pattern fallback (almost never taken)
- remove assert isinstance(feature.value, bytes) checks in _match();
add Bytes.value: bytes class-level annotation so mypy narrows the
type without the runtime check
- remove cache structure compatibility block from cache.py per reviewer
request to handle in a separate PR
- update test assertions from bytes_rules to bytes_prefix_index
