Revision history for Data-Intern-Shared

0.06      2026-09-26
          - DATA_INTERN_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.

0.05      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
          - 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.

0.03      2026-07-21
          - On-disk format change (v1 -> v2): an existing 0.02 file is
            refused; recreate it.
          - Resolve argument magic before capturing the path string.

0.02      2026-07-03
          - Security and robustness hardening; backing files now created mode
            0600 (pass a file-mode argument to new() for cross-user sharing).

0.01      2026-06-23
          - Initial release.
