Game::StrategyServer::MoveFleet — not checked by this run
- (high) on arrival: dispatches SEFleetArrived and runs one of three arrival handlers by destination kind (enter system / join fleet / stop at point) — declared input boundary -- an arriving call is expected to differ in all of it, and none of it is declared, so the compare says nothing about arrivals [guard:fleet sees the fleet's own words; the event and the system do not]
- (high) on departure: cancels every still-acting ship (with a log line each) and calls ServerSystem::FleetDeparts, which rewrites the system's ownership bits — writes through pointers to ships and to the system
- (medium) the tanker top-up refuels other ships in the fleet — the per-ship range regions would show it, but ours does not model it, so a fleet with a tanker diverges for a known reason
- (medium) a node-line waypoint's step comes from the stutter profile — NodeLineStep / BuildStutterSegments are written and unit-tested but not wired in; the hook steps every waypoint type as speed x dt, so a node-line leg is knowingly mis-stepped and only its type is recorded [declared gap: docs/B4.md]
- (medium) a missed probabilistic jump scatters the fleet in a random direction — the direction is a second draw whose mapping is not modelled; ours leaves the position alone and reports the scatter distance, so the generator region diverges by one word on a miss
- (medium) the route revalidation and the waypoint list itself — declared input boundary; the waypoint vector is not a region
- guard hits in compare mode: fleet+0xa0:4, fleet+0xdc:1, fleet+0x10c:1, fleet+0xcc:1, fleet+0xdb:2, fleet+0xe0:26
