re: the Stage 16 boss closed end to end; five disc fields the image never names

Browse Source 
New doc docs/re/structures/stage16-boss.md joining three iterations' pieces: the
data object (player-tuning-tables), the collision table (collisionset) and now the
loader.

sub_82315AE8 r11 is the boss loader, and it says so itself: 558 instructions, one
call site (sub_82308AB8), and its 21-entry block is 19 field names plus the
Japanese error "the boss's laser shell ID could not be obtained".

Zero partials: every one of the 19 is a Guardian or Core field -- 16 of Guardian's
19, 5 of Core's 10, DamageLevel1/2 shared.  The boss reads as a rotating,
vertically-moving platform with a guard cycle, three shell ids (AAGun, Laser,
HomingLaser -- the Shell_S16Boss_* set) and a Core that periodically drops
lock-on.

The residual is the finding: 8 disc fields the loader never names, and five of
them are not strings in the executable at all -- InitHight (the game's own typo
for Height) and the four DamageLevel{1,2}Bomb{,Rand}Time.  Controls: ChargeTime
(10 chars) and GuardTime (9) are the same shape and both ARE present, so it is not
an extraction artefact; HP (2 chars) is below the extractor's floor (shortest row
is 6); Radius exists but is generic.

So the disc carries fields no code names -- the mirror image of the usual trap, a
loader naming a field the disc never values.  Whether they are read positionally
or are dead data is not settled.
