Revision history for Data-Fenwick2D-Shared

0.05  2026-10-16
    - Fix shared-lock wakeups and frozen-data publication.
    - Recover sparse files safely and define counter wraparound.

0.04      2026-09-26
          - DATA_FENWICK2D_SHARED_SPARSE=0 reserves segments up front, so a
            full filesystem fails the constructor, not a later write.
          - A failed create no longer leaves a full-size file behind.
          - Checking a half-created file no longer allocates it on tmpfs.
          - Long paths no longer cut the reason from error messages.

0.03      2026-09-15
          - Recover a lock left ownerless by a corrupt file instead of hanging.
          - Fix a writer stall on ARM64 after readers release.

0.02      2026-08-12
          - A file left by an interrupted create is recovered, not refused.
          - freeze()/new_readonly(): sealed read-only mode, lock-free.
          - unlink() reports a failed removal; a missing file is no error.

0.01      2026-07-23
          - Initial release.
