Changes in version 0.1.0 (2026-09-05)                  

Initial release

  - Introduce the package as spatpersist with the focused public API
    persist_ids(), id_transitions(), id_lineages(), validate_ids(),
    plot_lineage(), and example_units().
  - Create persistent spatial identity, boundary-version, and lineage
    identifiers for longitudinal polygon data.
  - Configure continuity metrics, thresholds, one-to-one match rules,
    ambiguity handling, and maximum time gaps.
  - Preserve identifiers across reruns through registry reconciliation.
  - Reject exact same-period coextensive geometries that cannot be
    distinguished reproducibly by spatial evidence alone.
  - Preserve distinct fractional-second POSIXt periods when checking for
    same-period coextensive geometries.
  - Define identifiers as dataset-local and document deterministic
    consolidation when new evidence connects previously separate
    registry lineages.
  - Inspect transition evidence and lineage relationships with exported
    audit tables, validation checks, and lineage plots.
  - Exercise the package with synthetic examples, automated tests, and a
    reproducible scalability benchmark.
  - Document calibration and production workflows in the package
    vignette.
  - Lock the intentional public API with a regression test and add
    contributor guidance that requires synthetic or public reproducible
    examples.
  - Allow manual CI runs, cancel superseded runs, and bound check
    duration.
