- _main_load_last_solo_map: MIN clamp on the terminator index (house rule 18)
- _main_get_window_count: named single-window predicate and a PIN of the
local player count (reopens its park)
- _observer_update_command: timer/last-timer/flag pointer walk mirroring
the exact sibling observer_update_velocities (reopens its park)
Rejected: _observer_update_positions (same-value carrier copy of
remaining_time), _main_crash (January writes through a null pointer),
_effect_generate_part (mismatched csprintf varargs).
Stable diff: 0 regressions; parks 236 -> 234.
