apply_changes

act imperative

Free. Apply a change set in the saved format (get_project_schema part=changes) in one atomic, undoable step: floors (whole floors with every part), structures (buildings on the site), links (connections) and scenarios are put (added, or replaced by id) or removed, and floors.patch changes a floor part by part (fields to set; parts put or removed by id); everything the set does not name stays as it is, including other floors, other parts of a patched floor and edits made in Studio. dryRun: true validates and checks without changing anything and returns errors with paths, the summary (added, replaced, patched, unchanged and removed items; parts lost or overwritten on replaced floors; connections removed with their floors; ends pulled onto smaller floors; robot stations moved), the geometry checks of the floors and connections it touches (overlaps, narrow passages, doors that open nothing, parts off the floor, floors overlapping, floors over the routing side, steep or misaligned connections; reach: true adds unreachable zones), the current fingerprints and those after the change. base {floors|links|structures|scenarios: {id: fingerprint | null}} refuses the change when a whole item differs from the version it was made from (someone edited it); a patch's own base does so only for the fields and parts it changes, so the user's edits elsewhere on the floor stay and conflicts lists exactly which parts (by id) and fields were edited on both sides. Fingerprints are of items as the app keeps them (parts normalized, robot stations where the robot fits): the fingerprint of what you send, of the applied item and of an export read back are the same. Removing a floor removes its connections; scenarios must name places that exist afterwards; locked parts cannot change; removeUnlisted: true makes the site and scenarios exactly the set. Change sets over about 200 KB: action=write chunks (offset, data of up to 200000 UTF-16 characters; the first with totalCharacters, totalBytes and s…

Input schema

Property	Type	Required	Description
`expectedRevision`	string	no	Use revision from the most recent get_space or change. Needed to apply or dry-run; not to write or cancel an upload.
`action`	string	no	request_begin opens a live group with fixed request and baseRevision; request_commit closes its confirmed prefix into one Undo; request_abort reverses only that unchanged known prefix (groupId). Separate operation IDs for each control. Children use requestGroupId, independent operationId and owned expectedRevision; only edit_space/apply_changes/put_process_scenario/delete_process_scenario/edit_equipment are supported. No simulation, import, other mutations or Plan inside a group. Unknown/reload requires explicit Studio recovery, never blind retry. apply (default): apply changes, or the upload named by transferId. write: stage one chunk of a large change set. cancel: drop the staged upload.
`dryRun`	boolean	no	Validate and check without changing anything: errors, summary, checks and fingerprints.
`plan`	boolean	no	Propose one fixed request for human approval in Studio. Requires request. Agent tools cannot approve it; normal edits without plan are unchanged.
`request`	object	no	One changeset is one request: id is `${baseRevision.length}:${baseRevision}:<name>` (100 characters maximum including the prefix); keep id and baseRevision fixed from its first read. Commit operationId must exactly equal id (do not add a helper prefix); preview/upload operation IDs must differ. This binding is guaranteed for Studio UUID:counter revisions; overly long revisions/IDs are rejected, never truncated. After journal expiry or reload never replace baseRevision to retry. Request-specific Undo/Redo refuses another history entry. Optional scope:{floorId,partIds,attributes} permits only these existing parts and attributes, compared against actual stored data; collateral normalization, other inputs, additions, removals, array reordering and locked changes are refused. plan:true stages this fixed request for human approval in Studio; while pending, all agent writes are blocked until the person approves or cancels. External callers must supply request.scope explicitly; copied selection context alone does not enforce it.
`groupId`	string	no	Fixed request ID for request_commit/request_abort. Read get_space.authoringRequestGroup before deciding. Abort restores only a known unchanged successful prefix.
`changes`	object	no	The change set (get_project_schema part=changes): {site, structures, floors, links, scenarios: {put, remove}, removeUnlisted, base}.
`transferId`	string	no	—
`offset`	integer	no	—
`data`	string	no	—
`totalCharacters`	integer	no	—
`totalBytes`	integer	no	—
`sha256`	string	no	—
`minClearance`	number	no	Report passages narrower than this many metres.
`reach`	boolean	no	Also check, on the floors the change touches, which zones a pedestrian cannot reach from any gate (routing; slower on large sites).
`operationId`	string	no	Your own unique name for this change, such as a UUID; optional. Sending the same call again with the same operationId returns the earlier result (replayed: true) instead of applying it twice, and get_operation tells whether it applied. Use a new one for each new change.
`requestGroupId`	string	no	Attach this live edit to an open request group. Requires a fixed operationId and the current owned expectedRevision. Only the advertised five editing tools support groups.
