# Observability doors — additive only

Owner, 2026-08-20: approved look / shots / width-200 / 1bpp face / regime flipbook / operator loop / net 159 / predicate jail. **Additive only. Keep all existing older implementations as historical artifacts.**

## Untouched on purpose

| artifact | stays |
|---|---|
| `muhl_png.py` | every mode, including `watch` / `VERDICT` lines |
| `imgdiff.py` | CLI look. New page wraps the idea; it does not replace the file |
| `ground/MUHL_PNG.md` | the spec CAIRN typed |
| `host/muhl_copy_leftover_button.py` | leftover copy button |
| `host/muhl_fold_surface_add.py` | fold surface. `--submit` stays off unless the owner says so |
| `file_drop.py` | image compressor. New land uses it |
| `visual.js` / `8bit.js` | claim sprites. Net 159 is not a `from=` claim |

## New land

`look.html` · `shots.html` · `face.html` · `flipbook.html` · `loop.html` · `net159.html` · `host/muhl_operator_loop.py` · `width200.js` · this folder's law files.

New mode, new flag, new file. Never a changed or deleted old one.
