CHANGELOG (Unreleased): File::open_storage, raw data and v2 B-trees over
Storage, the tests and their corpus results (2026-09-26, tank; conformance
600 of 697, results.json identical to 8f59b2e). known-issues: what
open_storage does not do yet (no remote backend or block cache, read_at
counts of a one-pass read, v1 group lookups, whole-file VDS sources,
zero-copy methods, SWMR growth, hash-order error choice on damaged chunked
datasets). Design: M2 status and the choices made.
