description: Create a structured visual board from a scene or system.

# board
Define one diagram with the Board protocol and open it on the public viewer.
Done when preview returns `ok` with a `luluboard.app` URL and the matching
`open` line, or chat-only BMD Source is delivered.
## Identity
- **BMD ID** (`b_…`) is which board. **BMD Source** is the `.bmd` body. `--id` is
- BMD ID. Omit `--id` only to mint. `current` is the viewed pointer.
+ **BMD Source** is the `.bmd` body. The file has no identity. **BMD ID** (`b_…`)
+ is the cloud row on `#b:<id>`. `preview` encodes source plus client version `1`
+ into `#z:`.
## Script Macros
| Macro | CLI |
|---|---|
| `$DRAWER_CTL` | `python3 scripts/drawer_control.py` |
## References
Load the authoring contract before writing.
1. Keep this file at start.
2. Load [vocab](./references/vocab.md); it is the authoring contract.
3. Load [demo.bmd](./templates/demo.bmd) only when a complete example helps.
4. When using an icon, load [icons.json](./common/icons.json).
5. Load [viewer](./references/viewer.md) for `status` or the pointer protocol.
## Flow
1. Use the public viewer unless the user explicitly requests chat-only output.
2. No scene to draw (and not an update): run `$DRAWER_CTL preview --kind board`
- with no `--file` and no stdin body. Keep `id` (BMD ID) first, then `open`
- and `url`. Show the URL and stop.
- 3. For an update, edit this session’s last BMD Source. `<id>` is the BMD ID
- from this session’s last preview. If none yet, run step 2 first and keep
- that BMD ID. Leftover local cache may still be read with
- `$DRAWER_CTL get-source --kind board --id <id>`.
+ with no `--file` and no stdin body. Keep `url` first, then `open`. Show the
+ URL and stop.
+ 3. For an update, edit this session’s last BMD Source text. If none yet, run
+ step 2 first.
4. Infer the scene and author one BMD Source string that follows vocab.
- 5. For the public viewer, run `$DRAWER_CTL preview --kind board --id <id>` with stdin or
- `--file` when updating that board. Omit `--id` only to mint a new board.
- If it reports a DSL error, correct the BMD Source and rerun. Keep the BMD
- ID from stdout, then `open` and `url`. Show the URL and stop.
+ 5. For the public viewer, run `$DRAWER_CTL preview --kind board` with stdin or
+ `--file`. If it reports a DSL error, correct the BMD Source and rerun.
+ Keep `url` first, then `open`. Show the URL and stop.
6. For chat-only output, return one `board`-fenced block and stop.
## Open wording
Say one line with the URL, from stdout `open`:
| `open` | Say |
|---|---|
| `created` | The new board is now current. |
| `current` | This is the current board. |
## Boundaries
stdout `url` is the public hash link (`https://luluboard.app/#z:…`). CLI
success completes the skill; do not open the URL, drive the viewer, or
screenshot the layout unless the user explicitly requests visual verification.
Mint without meta or style. On update, leave those lines unchanged.
`preview` does not write `~/.cache/board/history`.
