re: retract 'the game batches elements that share a mode' -- its own log refutes it

I wrote that yesterday in HANDOFF, the finding page and INDEX. It is false: in
one main-menu frame, draws 5, 6 and 7 are three separate additive draws --
consecutive, identical blend state, not merged.

Only the one-way implication holds: elements inside one draw share a blend
state; sharing a state does not put elements in one draw. The wrong version
would have licensed the port inferring a mode for an element nobody observed,
which is the one thing that page must not do. The ptframe4 conclusion is
unaffected -- it is in the same DRAW as ptframe3, not merely the same mode.

that share a mode. `ptframe4` needs no separate argument: it is inside the same
additive batch as `ptframe3`.

🔴 **Correction to my own first phrasing of this, which said "the game batches
elements that share a mode".** That is false and would have let you infer a
mode for an element I did not observe. In one menu frame, draws **5, 6 and 7
are three separate additive draws** — consecutive, same state, not merged. What
holds is only the one-way implication: **elements inside one draw share a blend
state; sharing a state does not put elements in one draw.**
* **Read the table as per-element facts, not as a rule.** *Which field* selects
the mode is still unknown — nothing on the disc does it, and the batching means
the choice is made before the draw. Two additive menu draws (819×720 and
