15 is the biggest unnamed built-in: 1360 sites across 27 of 28 stages, with
an invariant (unit, double) operand shape. Joining every call site's unit to
its craft type through stage\UnitGroup_S<NN>.tbl resolves 1360 of 1360, none
unknown, and the values stratify hard:
capital hulls (Destroyer, Carrier, CruiserEX, Cruiser, Acropolis,
BattleshipEX, ASFrigate) 0-100
mobile craft (Elan 500, ArrowHead 400, DeltaSaber_T 400,
DeltaSaber_W 600, Attacker_S 250-400,
Phantom 300) 250-600
asteroid (mn040_Asteroid_Big, 74 sites) 0, only 0
Capital ships crawl, fighters run, the player's craft is fastest at 600, and
a rock never moves. That is a speed's signature.
Except turrets break it. UN_e007_ADAN_Turret carries 400 x89 / 280 x17 /
380 x4 / 250 x2 and UN_e008_ADAN_TurretPlus 450 x62 / 500 x2 -- 176 of the
1360 sites, 13%, at fighter-class values on something that does not move.
The asteroid is what makes this sharp rather than dismissible: a genuinely
immobile object gets 0 every single time, so "immobile things get junk" does
not explain the turrets.
So the operand is a craft-class-dependent scalar with speed's range and
ordering, but set_speed is not a sound reading of it. Left UNNAMED. The
handler writes [unit+196], initialised from [unit+192] at spawn; reading its
consumer is what would settle it.
