sylph-decoder 33e3c40a2d re: REFUTE my own units 5 and 6 -- pteff03a IS drawn, the reader was truncating
The two sweeps are batched into ONE additive indices=8 draw, two quads, and
my parser took the first v: match per line and discarded the rest. Every
analysis saw quad A and never quad B. No new capture was needed -- the same
logs units 5 and 6 used already contained it.

Both strips measured: opposite directions matching the declared -639->1521
and 1721->-839, and a size ratio of 1.301 against the declared sy ratio
800/600 = 1.333.

Unit 5 recorded that the PORT's renderer draws pteff03a and treated that as
the port being wrong. The port was right.

Third instance of this class in the corpus (palogo_anima and the six-quad
dump are the others): a truncating reader yields a clean, complete-looking
negative. Reading one raw draw line in full would have caught it -- indices=8
was printed on every line and says two quads outright.

F6 unit 6 — pteff03a is not submitted at any size: absent, not collapsed

🔴 REFUTED 2026-09-02 by f6-unit11-pteff03a-IS-drawn.md. pteff03a is drawn. It is batched with pteff03 into one additive indices=8 draw, and the parser behind this page read only the first vertex of each draw line. The negative below is an artefact of the reader.

Status: measured ⟨capture⟩ ×1. 2026-09-02.

Question: is pteff03a absent from the draw stream, or submitted at zero / collapsed scale? Look at: any quad travelling right-to-left, at any size. Pass = found; fail = none. Not covered: why it is absent — still unknown.


Unit 5 filtered on height, so a collapsed quad would have been invisible to it by construction. This scan drops that filter.

Whole title era, frames ≥ 700, every quad regardless of size:

RIGHT->LEFT travellers  (pteff03a's declared direction):   0
LEFT->RIGHT travellers:                                    2   (both pteff03)
static shapes:                                            10
degenerate/collapsed quads (w<0.02 or h<0.02):             0

Not one quad travels right-to-left in the entire title era, at any size, and nothing is submitted collapsed. pteff03a is absent from the draw stream — not drawn invisibly, not drawn at zero scale.

This strengthens unit 5 from "no tall quad of that size" to "no quad of that motion at all", which is the stronger statement and the one that matters.

🔴 All three candidate mechanisms are now dead, and I have no fourth

candidate status
a zero-alpha skip weak on its own terms — it explains opening frames, not a whole run, and the leaf reaches non-trivial alpha well inside the captured window
a focus/variant link selecting one of the pair eliminated by the port: the linked targets chain across unrelated element kinds — on one menu a sweep points at a button — so the field is a chain pointer, not a variant selector
collapsed scale eliminated here

So the honest position is that neither agent has a mechanism. The element is declared in GP_TITLE build 4 as ptloop02.rat, element 12, beside ptloop01.rat as element 11 — identical pivots, identical keyframe times — and the game never submits it.

⚠️ I am recording that as the state rather than proposing a fourth candidate. Three have now been named and three have failed, two of them by a check that took minutes. A fourth guess before the human's "one streak or two?" look would be guessing against an answer that is about to arrive for free.

Reach

⟨capture⟩ ×1, one boot, the title era of one window. The scan is exhaustive over every quad in the stream, so the absence is not a filtering artefact — which was the specific weakness of unit 5 that this unit exists to close.
