Revision history for Data-MinHash-Shared

0.03      2026-08-12
          - Recover a file left behind by an interrupted create instead of
            leaving the path unopenable.
          - Frozen read-only mode: freeze() seals a file-backed structure;
            new_readonly() maps it O_RDONLY and queries it lock-free.
          - Documentation and test-harness corrections.
          - unlink() reports a removal that failed; one already gone is not an
            error.

          - Add b-bit MinHash (bbit_similarity / bbit_signature / bbit_similarity_of).
          - Copy the first signature before reading the second in bbit.
          - Resolve argument magic before capturing the path string.
          - Re-read the class name at the point of use in the constructors, so
            a later argument's magic cannot dangle the INPUT-captured PV.
