The master suite's fitness test failed twice on 125ac8b at the "out of stage 1" step.

Cause: the test's wait, not the time-up.

• until gives the runner 15 s to be warped out, counted from the runner's arrival on stage 1.
• The race also lasts 15 s (900 s scaled by 60), counted from the GM's /start.
• So the only slack was the second or less between /start and the arrival. Against that come the 100 ms field tick and the warp itself, which can take longer when the suite runs other tests at the same time.

The server side is fine.

• The runner got its countdown on stage 1, so the race was running there.
• end_race warps every occupant who isn't a GM.
• The failing trace has the last notice, at 14.83 s, but not the end, at 15.02 s, which is consistent with the wait running out first.

Change

• trace::until_within(c, trace, wait, done) waits for a given time; until now calls it with 15 s.
• The time-up step in fitness.rs waits 30 s.

Verification: fitness passed three times in a row on a fresh lane stack, and gm_ban passed alongside it.
