nocter-persistent

Responsibility

Provide dependency-free persistent vector and ordered-map storage for compiler authorities that need cheap immutable branching.

Contract

The crate exposes generic structural storage only to reviewed semantic owners. It has no knowledge of Nocter types, compiler phases, recovery policy, or source identities.

Invariants

• Cloning a collection shares unchanged roots.
• Updates copy only bounded structural paths.
• Iteration visits tree nodes linearly and does not restart lookup for every element.
• Domain-specific lineage and commit policy remain outside this crate.
