Module capability 

Capability classification cache.

Stores (profile, bucket?, op) → CapabilityRecord in memory with a configurable TTL (default 30 minutes). Future tasks may add disk persistence via redb; the API surface is deliberately designed to accommodate that without changing call sites.

OCP contract

• Add a new capability class: add a CapabilityClass variant + one arm in record_from_error. Existing arms are untouched.
• Add a new error pattern to classify: add one match arm inside record_from_error. The enum and store are unaffected.
• Add a new scope for clear: add a ClearScope variant + one arm in CapabilityCache::clear. Existing scopes are untouched.
• Storage-class extraction uses a small substring scan; new storage class names (e.g. DEEP_ARCHIVE_IA) are recognized automatically when they appear in the error message after "InvalidStorageClass" or "NoSuchTransition".

SystemClock 🔒

Enums

CapabilityClass

Classification of a single S3 operation’s capability for a (profile, bucket?, op) triple.

ClearScope

What entries to remove when CapabilityCache::clear is called.
