Module reader 

CommitReader: encapsulates the commit->metadata->shard key derivation chain.

This is the void-core version that adds void-core-specific methods:

• collect_ancestor_content_keys() – needs ObjectStore + Commit types

Low-level crypto primitives are delegated to void-crypto.

Structs

CommitPlaintext

Decrypted commit plaintext bytes.

CommitReader

Encapsulates the key derivation chain for reading a commit’s objects.

DecryptedShard

Decrypted shard bytes (zstd-compressed body + optional padding).

Functions

collect_ancestor_content_keys_vault

Collect content keys from ancestor commits for shard decryption fallback.

decrypt_shard_data

Decrypt a shard blob with wrapped key support.
