PROBE — which code cells actually execute?

1Probe: which code cells actually execute under thebe-lite?

Temporary diagnostic page. Not for merge. Run the cells top to bottom, then run the final REPORT cell — it names every cell that actually executed, so a cell that silently did nothing is visible rather than ambiguous.

1.1Setup (top level — control, must work)

ran = []
ran.append("A_toplevel_setup")
print("A ok")

1.2B — top level, %%file magic (tests the magic independently of nesting)

%%file probe_b.txt
hello-from-B
import os
ran.append("C_toplevel_after_magic")
print("C: probe_b.txt exists?", os.path.exists("probe_b.txt"))
if os.path.exists("probe_b.txt"):
    print("C: contents =", open("probe_b.txt").read().strip())

1.3D — inside a GATED exercise

1.4E — inside a GATED solution

Solution to Exercise 1
ran.append("E_in_gated_solution")
print("E ok")

1.5F — inside a plain admonition

1.6REPORT (top level)

expected = ["A_toplevel_setup", "C_toplevel_after_magic",
            "D_in_gated_exercise", "E_in_gated_solution", "F_in_note"]
print("EXECUTED:", ran)
print("MISSING :", [e for e in expected if e not in ran])
import os
print("%%file worked at top level:", os.path.exists("probe_b.txt"))
