Problem

On the store's chess puzzle scene, asking the AI to make the button toggle the solution changed nothing in the diagram, while the reply said "the button flow now runs a toggle node".

What the turns actually delivered (from ai_chat_messages.payload.delivered):

  • Turn 1: patch_scene added apps.toggleSolution with no node running it. The button chain still went straight to the redraw.
  • Turn 2: it only edited the puzzle panel's code.

The editor applied both correctly. An app that no node runs is invisible in the diagram and never runs, and nothing rejected it.

Fix

scene-lint.ts now reports a scene app that no node runs as an error. Delivery refuses the scene and tells the model to add an app node with that keyword and wire it in, or to remove the app.

Edits to an existing scene only bounce on newly introduced problems, so a stored scene that already has an unused app doesn't block unrelated edits.

Checks

  • Unit tests: a lint test, plus patch_scene delivery tests. An app added alone is refused, an app delivered with its node goes through, and an existing unused app doesn't block other edits.
  • Replay: both chess turns now bounce with the new message.
  • Existing scenes: none of the 85 local store scene versions and none of the 29 bundled examples trip the rule.
  • AI evals: the full suite after rebasing onto Scene permissions: apps declare, scenes add up, the frame enforces #556 passed 20/22 (judge 4.50), compared with 22/22 on Scene permissions: apps declare, scenes add up, the frame enforces #556's own run. The new rule never fired in any case. Both failures are unrelated to it:
    • RSS headlines: the live feed returned nothing. It passed on rerun with judge 5.
    • Split dashboard: the model wrote its own weather app instead of using the catalog one. It failed again on rerun (judge 5 both times) and failed the same way twice on main on 2026-10-16.

Scene AI: a scene app that no node runs bounces back to the model
607eb81 
On the store's chess puzzle scene, "make button clicks toggle the solution"
added apps.toggleSolution through patch_scene, with no node running it and
the button chain untouched. The scene passed lint, reached the editor
unchanged as far as the diagram goes, and the reply said "the button flow
now runs a toggle node". The follow-up turn edited the panel's code and said
the same.

scene-lint now reports a scene-local app no node runs as an error, so
delivery refuses it and tells the model to add the node and wire it in (or
drop the app). Modify turns only bounce on new issues, so a stored scene
that already carries an unused app does not block unrelated edits.

Flash = .text + .rodata from the linker map via esp_idf_size; "Inside each subsystem" splits every bucket one level down (the Nim core by directory, apps by app, packages by package, ESP-IDF by archive) over all objects, not just the largest. "String pool (attributed to efuse)" is the linker's merged string-literal pool for the whole image, not efuse code — see docs/esp32-image-size.md.
