Tommaso BianchiandClaude Opus 5 3c7105202a The offer ladder stops depending on what ran before it
It passed alone and failed inside scripts/ladder-all.sh, twice, on the same property: "right-click
with two picked -> None". The diagnostic it now prints said what a screenshot could not — editing=True
with an empty selection after two clicks that should have picked two entities. Three rig facts, all
about the DRIVER, none of them a product defect:

A LEFT-CLICK ON A LINE'S MIDDLE OPENS ITS LENGTH FIELD. The Select branch tests m_live_quotes before
it picks, with a ~24 px label tolerance, and a line's Length quote sits at its midpoint — so the
click that was meant to select it promoted a dimension and froze the canvas instead. Everything
after it landed on nothing. It bit only when the previous step had left that line selected, because
live quotes are drawn for the SELECTION: hence passing alone and failing in the gate. Lines are now
picked at 0.3 along, clear of the label.

A FIELD THAT HAS NOT OPENED YET READS LIKE ONE THAT NEVER WILL. The queue opens each field from a
CallAfter, so a driver that looks once, sees nothing and moves on gets frozen by the field that
arrives a moment later. keep_as_drawn() now waits for QUIET — two consecutive clear readings — and
draw_line_at drains stragglers before handing back.

A KEY CANNOT CANCEL A SESSION WHOSE CANVAS IS FROZEN. gui-ladder's enter_sketch dismisses the old
sketch with Escapes, which an open field swallows, so the session survived and the four calibration
probes landed in it on top of what was already there: "calibration expected 4 points, got 7". Every
rung now enters through fresh_sketch(), which cancels through the socket first — that cannot be
swallowed.

Measured after the fix, in the sequence that failed: gesture ladder 93/93 then offer ladder 108/108,
back to back on the same app.
