P29: until now a block was only stored after ▶. A learner who pressed only «Tests», the main button in Etappe 2, lost the change on reload.

How it works

• ▶ already clicked LiaScript's hidden run button. LiaScript then stores the block (a new entry in its code history, kept across a reload and, from version: 1.0.0 on, across closing the tab) and runs the per-run script, which calls session.run(source).
• «Tests» and «Visualisieren» now click that button too. Before the click they note their command in the session (commandAfterLiaRun).
• run, called by the per-run script, then sends that command instead of glpython:run. Python runs once, and the console shows what it showed before.
• The per-run script and the embed are unchanged, so no protocol change and no glpython-editor PR.
• A note older than 10 seconds is dropped, in case LiaScript doesn't run the block. Without LiaScript's button (no code block), the command goes to glpython directly, as before.
• The course's @Notiz stores its fields the same way (it clicks LiaScript's run button).
• Unchanged code: LiaScript itself adds no new version when the code didn't change (measured below).
• Several files (-noten.py / +main.py): LiaScript stores the whole group, as with ▶.
• Blocks without features=tests: unchanged. «Visualisieren» stores there too.
• README: one sentence in the section on ▶ and LiaScript's code history. No new texts.

Tested in LiaScript

Hosted player in Chrome. A course with version: 1.0.0, this macro served locally, the deployed embed. Inside the embed frame I recorded every message from the macro, to count runs.

Step	Single block	Group noten.py + main.py
Change, then only «Tests»	version 0 → 1; messages ["glpython:test"]; console «Programm läuft · 1 von 1 Beispielen bestanden» (output once, report once)	0 → 1; ["glpython:test"]; «Hauptprogramm · 1 von 1 …»
«Tests» again, unchanged	stays 1; ["glpython:test"]	stays 1
Reload	change there, version 1	change there
Change, then «Visualisieren»	→ 2; ["glpython:visualize"]	→ 2; ["glpython:visualize"]
Reload	change there	change there
Change, then ▶	→ 3; ["glpython:run"]	→ 3; ["glpython:run"]
Reload	change there	change there

Before (macro on main), same test: after «Tests» and «Visualisieren» the version stays at 0, and after a reload the change is gone.

check-macro passes.

Your manual tests

1. Chrome, desktop, a course with version: 1.0.0 (Etappe 2):
   • Change a block, press only «Tests», reload: the change is there, the version arrows show a new entry, and the console shows the program's output and the report once.
   • «Tests» again without a change: no new version.
2. «Visualisieren» the same way: change, «Visualisieren», reload.
3. ▶ as before.
4. A block group (-noten.py / +main.py): change noten.py, «Tests», reload. The change is kept.
5. A block with a profile without tests (e.g. @Code.erkunden): «Visualisieren» stores it.
6. iPad: 1 and 2. Then close the tab and open the course again: the change is still there (version: 1.0.0).

Follow-ups

• 10-second window: if LiaScript takes longer than 10 seconds to run the block after the click (I've never seen it), the note expires. Then that click runs the program instead of testing it; the code is still stored.
• Buttons inside the embed («Beispiel visualisieren» for a failing example, «Visualisieren» on a REPL entry) still go directly to glpython. They don't change the code, so there's nothing to store.
