"""PMP -- Personal Memory Protocol reference node.

A local-first, user-owned memory substrate: a signed append-only
operation log plus import adapters that turn calendars, notes, and photo
metadata into provenance-tagged evidence operations.

Public API surface for embedders::

    node = LocalNode.init("~/.pmp/laptop", name="laptop")
    result = node.import_source("ics", "calendar-export/")
    for op in node.list_evidence("calendar.event"):
