Uninitialised locals get values (debug vertex, datastore result, index
buffer, map tool direction, AI entry points, escape alignment, grenade aim
from a vehicle, game options descriptions, unreachable switch arms), the
AI's squad and platoon records move whole, a speech cause point is read,
the geosphere's out-of-memory path frees itself, a console cond clause
without a result is refused, and the crash reporter rejects truncated map
files. Gameplay the original game has, kept so it plays the same, is noted
in a line rather than a page.
