CI task 261 at fd6af84 went red on a single check in module 18: "an
exec edge firing every frame carries an evenly spaced chain of beads"
measured a gap of 0.611 instead of 0.5 +- 0.1. The code did not
change. The tolerance was tighter than one slow frame.
- A bead leaves on the first frame at least 0.15 s of game time after
the one before, which is 0.5 of the 0.3 s trip. The gap is therefore
that plus up to one frame.
- One 33 ms frame right after the screenshot gives exactly 0.611.
- The check now wants a gap above 0.49 and below 0.5 plus one frame of
up to 50 ms.
Tests:
- e2e 18 on the final build: ALL PASSED, 33 checks.
- Counter-probe with a minimum spacing of 0.1 instead of 0.15: the
check fails with 0.333, and only this check.
