0521 - Quasi-immutable linked-entry storage with validity states and configurable search policies
Summary: A quasi-immutable database can be represented as a series of linked entries where newer entries are inserted at the top. Each entry may have a state (valid/invalid, most recent/older) or a counter to denote recency. Agents can update states when inserting new records, and different agents can apply different search policies (e.g., find most recent, find all valid, find N most recent).
