# 2026-07-09 — Multi-select machine delegation

```
Type: log
```

## Intent

Land machine-work multi-selection: one frontend selection set, bulk mode
assignment in both UIs and agent mode, without bringing back per-channel
weight verbs.

## Changed

- `Sim::set_machine_modes` applies one `MachineMode` to many ids.
- Terminal: frontend `selected_machines`; `Shift+t` box select; `1`–`4`
  assign; `Esc` clear; selection hint in the playing frame.
- Bevy: marquee drag, shift-click toggle, shared `1`–`4` / Esc; rack tint
  for selected tiles.
- Agent: `select box|add|toggle|list|clear`; `delegate selected <mode>` and
  bare `delegate <mode>` when a selection is active.
- Wiki: machine-work.md AC1, ROADMAP #33, terminal/bevy/agent-play interface
  docs, DEVLOG entry.

## Checks

- `./tools/seed-cargo-target.sh` (when needed), then `./tools/check.sh`.

## Next

- Non-host mode production, route animation, Schemes-as-mode decision
  (ROADMAP #33 remainder).
