name: 4Paradigm change logs
note: >-
  4Paradigm keeps no company-wide changelog. Two of its three open-source products publish one, and
  they are moving at completely different speeds: PhanthyMotus ships dated, categorised entries several
  times a week, while OpenMLDB has published nothing since February 2025.

      Key-based peer identity, six-digit pairing, requests signed against a pinned key, three
      authorisation gates before a peer can move anything. Discloses two of its own defects: a
      keyword-based permission check that let a read-only peer drive locomotion, and a safety config
      flag read by no code.
