• 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

• sqlstring

  Only one read-only SELECT over named datasets is accepted. File readers, file-relation shorthand and engine path or definition discovery are refused before binding with sql_rejected, including nested SQL and computed targets. File-referencing PROJ coordinate definitions are also refused before native projection use, including computed or per-row values; EPSG identifiers and inline definitions without files remain supported. Unknown tables receive the same sql_error whether hidden or nonexistent, without catalogue suggestions. Engine errors do not expose filesystem paths or internal statements; input positions are retained when available. Existing saved SQL is retained unchanged; affected saved and published queries fail.

• styleStyle

• visibleboolean

• tooltiparray of stringor null

  Fields shown in the hover tooltip; null = automatic.

• popuparray of stringor null

  Fields shown in the click pop-up; null = automatic.

• publishedFieldsarray of stringor null

  The author's explicit published-field list; null = the derived minimal projection (style, label, tooltip/pop-up, live-filter, timeline and published-widget fields). Published responses carry exactly the effective set; fields the published map needs to render are always published, whatever this lists.

• inLegendboolean

  Whether the layer contributes to the legend.

• vizViz

• filtersarray of LayerFilter

  Refinements applied before aggregation; the SQL stays the source of truth and [] restores it exactly.

• legendTitlestringor null

  Legend title override; null = the layer name.

• legendLabelsarray of string or nullor null

  Per-entry legend label overrides; null entries (and null itself) keep the automatic labels.

• legendAttrsobjector null

  Per-channel legend attribute-name overrides, keyed by channel (fill, stroke, radius, width). Three states per channel: a missing key (and null itself) keeps the automatic attribute name, a string overrides it, and a null value hides that channel's attribute line. An override drops automatically when its channel's driving attribute changes.
