PublishedFieldsStatement

object

Per-layer statement of the effective published field set.

• editRevisionstringpattern ^[0-9a-f]{32}$

  Opaque durable revision paired with this document state. Camera and derived writes do not change it.

• lastChangedAtstringor nullformat date-time

  Time of the last accepted covered change, independent of camera and cache clocks.

• lastChangedBy

  A named actor has display and fixed SQL names. { deleted: true } explicitly identifies a deleted actor and carries no names or profile fields. Null explicitly means unknown. Never inferred from ownership.

    • namestring

    • hiddenboolean

      A hidden layer shares nothing — it is absent from the published surface entirely; its statement carries an empty field set.

    • modestring

      derived = the minimal projection; list = the author's explicit published-field list.

        • namestring

        • requiredboolean

          The published map cannot render without it; no list can remove it.

    • availablearray of string

      Every field an explicit list could name. Empty on aggregated layers, whose computed columns are the whole wire.

    • listarray of stringor null

      The author's raw explicit list, verbatim (null = derived). Editors write against this, never against the effective set.

    • errorstring

      Present when this layer's fields cannot be resolved; the other layers still answer.
