Revision history for Data-TopK-Shared

0.07  2026-10-16
    - Fix shared-lock wakeups.
    - Reset the decay clock when clearing a timestamped summary.
    - Clarify process-sharing limits.

0.06      2026-09-26
          - A writer killed mid add, clear or decayed rescale is repaired by
            the next lock holder; every key is found again.
          - Segments are reserved, so a full filesystem fails the constructor;
            DATA_TOPK_SHARED_SPARSE=1 skips the reservation.
          - A failed create no longer leaves a full-size file behind.

0.05      2026-09-15
          - Recover a lock left ownerless by a corrupt file instead of hanging.
          - Fix a writer stall on ARM64 after readers release.

0.04      2026-08-12
          - Recover a file left behind by an interrupted create instead of
            leaving the path unopenable.
          - Documentation and test-harness corrections.
          - unlink() reports a removal that failed; one already gone is not an
            error.

0.03      2026-07-30
          - Reject a non-ref invocant replacement in the re-entrancy guard: a
            hostile tied or overloaded argument could crash the process mid-call;
            it now croaks cleanly.

0.02      2026-07-21
          - Add time-decayed mode (new_decayed/new_decayed_memfd, half_life,
            is_decayed) for recency-weighted top-k.
          - On-disk format change: 0.01 files cannot be opened by 0.02.
          - Resolve argument magic before capturing the path string.

0.01      2026-07-10
          - Initial release.
