# Circuit List Editor API
## Scope
The circuit-first editor uses tree, circuit, row and project-device endpoints.
All paths below are mounted below `/api`. There is no Consumer application API.
Project responses from `GET /projects` and `GET /projects/:projectId` include
`currentRevision`. Versioned project commands use this value for optimistic
concurrency checks.
### Project Commands and History
- `GET /projects/:projectId/history`
- returns `currentRevision`, `undoDepth`, `redoDepth` and the current top
change-set id for both persistent stacks
- `POST /projects/:projectId/commands`
- executes a supported versioned command as a new user revision
- body: `{ "expectedRevision": 0, "command": { ... } }`
- `POST /projects/:projectId/history/undo`
- `POST /projects/:projectId/history/redo`
- body: `{ "expectedRevision": 1 }`
- executes the eligible inverse or forward command as a new auditable
revision
The public dispatcher currently supports `circuit.update`, `circuit.insert`,
`circuit.delete`, `circuit-device-row.update`,
`circuit-device-row.insert`, `circuit-device-row.delete` and
`circuit-device-row.move` plus
`circuit-device-row.move-with-new-circuit` and `circuit.reorder-section`, all
with schema version `1`. Other command types are rejected. Insert commands
contain the complete entity or circuit block with stable ids; delete commands
include the expected parent identity. Circuit snapshots contain zero, one or
multiple complete device rows. Move commands contain each row's expected and
target circuit plus its exact expected and target sort order. This makes
deletion and moves undoable without generating replacement identities or
renumbering circuits. The editor does not consume these endpoints yet.
`circuit-device-row.move` targets existing circuits in the same circuit list.
`circuit-device-row.move-with-new-circuit` atomically creates exactly one
explicitly identified empty target circuit and moves one or multiple existing
rows into it. Its inverse restores every row to its exact prior position and
deletes the generated circuit only if its fields and complete row set still
match the recorded state.
`circuit.reorder-section` requires one assignment for every circuit currently
in the section. Each assignment records the expected and target `sortOrder`.
The command and its inverse change no circuit field other than `sortOrder`;
equipment identifiers and complete device-row blocks remain unchanged.
Example:
```json
{
"expectedRevision": 0,
"description": "Rename circuit",
"command": {
"schemaVersion": 1,
"type": "circuit.update",
"payload": {
"circuitId": "cir_1",
"changes": [
{ "field": "displayName", "value": "Sockets East" }
]
}
}
}
```
A stale `expectedRevision` returns HTTP `409` with
`PROJECT_REVISION_CONFLICT`. Undo or redo without an eligible stack entry
returns HTTP `409` with `PROJECT_HISTORY_OPERATION_UNAVAILABLE`.
## Circuit-First Endpoints
### Distribution Board Setup
- `POST /projects/:projectId/distribution-boards`
- atomically creates the distribution board, its circuit list and all default circuit sections
### Tree Endpoint
- `GET /projects/:projectId/circuit-lists/:circuitListId/tree`
- Purpose: returns section/circuit/device-row tree with calculated row and circuit totals.
Response sketch:
```json
{
"circuitListId": "cl_1",
"sections": [
{
"id": "sec_1",
"key": "lighting",
"prefix": "-1F",
"circuits": [
{
"id": "cir_1",
"equipmentIdentifier": "-1F1",
"circuitTotalPower": 4.2,
"deviceRows": [
{
"id": "row_1",
"displayName": "Office lights",
"rowTotalPower": 1.8
}
]
}
]
}
]
}
```
### Circuit CRUD
- `POST /projects/:projectId/circuit-lists/:circuitListId/circuits`
- create circuit in list/section
- `POST /projects/:projectId/circuit-lists/:circuitListId/circuits-with-device-rows`
- atomically create one circuit and one or more initial device rows
- `PATCH /circuits/:circuitId`
- update circuit-level fields (BMK, protection, cable, reserve flag, etc.)
- `DELETE /circuits/:circuitId`
- delete circuit (and related rows via DB relations)
- `GET /circuit-sections/:sectionId/next-identifier`
- preview next identifier for section (`prefix + maxSuffix + 1`)
Request sketch (`POST .../circuits`):
```json
{
"sectionId": "sec_1",
"equipmentIdentifier": "-2F14",
"displayName": "Sockets East",
"sortOrder": 140
}
```
### Device Row CRUD
- `POST /circuits/:circuitId/device-rows`
- create row inside a circuit
- `PATCH /circuit-device-rows/:rowId`
- update row values
- `DELETE /circuit-device-rows/:rowId`
- delete row
### Move Device Row
- `PATCH /circuit-device-rows/:rowId/move`
- Purpose: move one row to existing circuit or to newly created circuit in target section.
Request sketch:
```json
{
"targetCircuitId": "cir_target"
}
```
or
```json
{
"targetSectionId": "sec_target",
"createNewCircuit": true
}
```
### Bulk Move Device Rows
- `PATCH /circuit-device-rows/move-bulk`
- Purpose: move multiple rows in one command flow.
Request sketch:
```json
{
"rowIds": ["row_1", "row_2"],
"targetCircuitId": "cir_target"
}
```
### Reorder Circuits
- `PATCH /circuit-sections/:sectionId/circuits/reorder`
- Purpose: persist explicit circuit order within one section.
Request sketch:
```json
{
"orderedCircuitIds": ["cir_2", "cir_1", "cir_3"]
}
```
### Renumber Section
- `POST /circuit-sections/:sectionId/renumber`
- Purpose: explicit renumbering by section prefix; never implicit on move/sort.
### Safe Equipment Identifier Update
- `PATCH /circuit-sections/:sectionId/equipment-identifiers`
- Purpose: apply explicit per-circuit identifiers safely even with unique constraints.
Request sketch:
```json
{
"identifiers": [
{ "circuitId": "cir_1", "equipmentIdentifier": "-2F1" },
{ "circuitId": "cir_2", "equipmentIdentifier": "-2F2" }
]
}
```
## Removed Legacy Endpoints
The former `/consumers` read/write endpoints were removed after every retained
consumer had a verified Circuit-First migration mapping. Database upgrade tooling
reads retained legacy rows directly; application features must use the Circuit-First
endpoints above.
## Linked Project Device Review
- `GET /project-devices/projects/:projectId/:projectDeviceId/links`
- returns all linked circuit device rows with distribution-board/circuit context and field differences
- `POST /project-devices/projects/:projectId/:projectDeviceId/synchronize`
- applies only explicitly selected fields to explicitly selected linked rows
- `POST /project-devices/projects/:projectId/:projectDeviceId/restore`
- restores the captured pre-sync values for session-local undo
- `POST /project-devices/projects/:projectId/:projectDeviceId/disconnect`
- disconnects explicitly selected rows without changing their local values
- `POST /project-devices/projects/:projectId/:projectDeviceId/reconnect`
- restores a disconnected link if the row has not been linked elsewhere meanwhile
`displayName` is included in the comparison but is not selected by default in the UI. Updating a
project device never triggers synchronization implicitly.
