 - **The short list shows a trip's event next to the trip**, without it counting as one of the 3 events: a delivery with a detour still reads as a quick check-in.
 - **The hull bar colours** follow the rules: amber below 50% (no Dangerous cargo), red below 25% (Needs repair).
 - **Developer tools: Damage hull** sets a ship to 20%, to try the warning and repairs (the CR's manual check).

+- **A sleep test's world is fixed now** (`fleet-sleep.test.ts`, "trips in flight still pay"): each test company gets a random world, and with events shifting trip times, a world sometimes had no trip in the air at the sleep time, failing the check that one lands after it. Seen as an intermittent failure after Step 26.7's commit; fixed in a follow-up commit.
