Version Chain Management
A chain with gaps is worse than no chain, because it implies continuity that does not exist. Gaps arise ordinarily: a document is exported, edited offline and re-uploaded as a new record, severing its ancestry. From that point the estate holds two documents that are really one, each with partial history, and no automated process can reconnect them. Preserving the chain is largely a matter of keeping editing inside the governed system.
Centralpoint keeps the chain intact by treating revision as a state change on the record rather than as a new upload, so lineage survives editing. For retrieval this matters because a question about a document's evolution can be answered across its full history rather than from whichever fragment happens to be indexed.
