The phase is FUN_007c2350 (tail phase 34): for every player, over every ship of
every fleet, gated on a two-bit-per-player field at Ship+0x54 that is NOT on the
wire, call RecordObservedDesign(player, ship.design). That function dedups on
odid alone, and on a hit it ERASES and PUSH_BACKS rather than updating in place --
so the list is ordered by last observation and otnF survives the move -- then caps
the list at 20 entries per DESIGN-OWNER, counted from the back, after every single
record call. sizeof(ObservedDesign) = 0x10.
Predictions, computed from a Python simulation of that mechanism over the corpus,
committed before any engine code is written:
P1 rich turn odes: 55 -> 21, i.e. 34 closed / 0 regressed
P2 otch+owep (24 leaves): 0 closed / 0 regressed, blocked (see the finding)
P3 rich-turn total 1092 -> 1058
P4 canonical pair: 1 closed / 0 regressed
P5 the NPC-owner guard is worth 4 leaves of regression on the canonical pair
