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`, 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` currently targets existing circuits in the same
|
||||
circuit list. Creating a new target circuit while moving rows is not yet part
|
||||
of the persistent command API.
|
||||
`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.
