Module document 

Immutable PDF revision index over caller-owned original range acquisition.

Structs

Document

A source-bound immutable index. Reading metadata is distinct from checking signatures or accepting document permissions and certificate trust.

Graph

Full indirect closure of a historical catalog, including null references. Backlinks do not recurse or create reference-counted ownership cycles.

GraphMembers

Paid fused direct member traversal using the existing linked-member core.

GraphObject

A node inside the actual graph owner. Resolution cannot substitute a node from another revision or silently use a newer generation’s definition.

Reading

Independently retained object metadata and any decoded source storage. Encoded file strings remain ranges in the immutable original document.

Revision

Historical trailer and exact terminal record belonging to one update.
