Module github_read_cache 

Durable cache rows for rendered GitHub issues and pull requests.

The cache belongs in AFT’s existing aft.db. Keeping the effective authentication identity as a cryptographic hash prevents cache rows from exposing credentials while still keeping principals strictly isolated.

Structs

GithubReadCacheEntry

Cached canonical text and the timestamps used for cache freshness decisions.

GithubReadCacheKey

Exact durable cache key for one GitHub resource and authentication identity.

Enums

GithubReadResourceKind

The GitHub resource type that selects a cache namespace.

ensure_github_read_cache_schema

evict_hard_expired_github_read_cache_entries

Delete rows whose source-fetch time has reached the hard-TTL cutoff.

invalidate_github_read_cache_resource

Invalidate a resource across identities, or only one identity when supplied.

lookup_github_read_cache_entry

Look up one cache row using the full resource and authentication-identity key.
