port: take the completed EXTRAS blend set, and record two refutations that land on me

Browse Source 
EXTRAS whole-screen residual 1.97 -> 0.63; ptframe4 31.90 -> 1.14, pteff21/22/23
from 12-14 to under 0.8. The four elements I reported as in no draw were in a draw
all along -- the vertex dump was capped at two quads and the batch holds six, so
four were dropped with a well-formed line and no ellipsis. Same failure class as my
MIX-default material: the run completed, the output parsed, the answer was wrong.

Their pteff10 flag, tested by holding it alpha-over with everything else additive:
tone-corrected residual 0.630 additive against 1.704 alpha-over, but raw RMSE 12.91
against 9.98. They disagree because the port already renders +8.50 levels brighter
than the capture on this screen before any of this, so raw RMSE punishes added
light whether or not the light is right. Adopted on the measurement plus the
structural metric; extras raw-rmse went 11.43 -> 12.88 and that is stated, not
hidden. The differing region halved, 0.07 % -> 0.03 %.

Refuted, mine: "every decoration 0x0 and every button 0x3002" was a two-screen
generalisation I called a confirmation, one message after objecting to exactly that
move in their page. My own export held the counter-examples -- ptbtn00 is 0x73002
and my exporter calls it unknown rather than button; three title elements are
0x3000, button-shaped and not focusable. kind & 0x2 is the focusable flag.

Refuted, mine: the sweeps DO run on the main menu. Their log retains NDC and both
strips overlap the screen in every captured frame, stepping in opposite directions
with vertex alpha ramping. My phase sweep measured that the PORT'S sweeps make the
match worse, which is a statement about my rendering, not about the game. A
best-match argument for an absence cannot separate "not there" from "there and
drawn wrong", and I had that caveat written down and read past it.

Not flipped: the strips are additive with a ramping vertex alpha and the port has
neither on the leaf path, so enabling the loop today would be more correct in
behaviour and worse on screen. The ramp is asked for. What changed today is the
claim -- the port is wrong here and now says so.

Oracle: `publisher_logo` 1.00 %→**0.75 %**, `developer_logos` 0.39 %→**0.33 %**, `extras`' differing region collapsing from 736×525 to **398×295 at the sweep position**. 🔴 Open cost: `sylpheed-cli` builds from the workspace crate, so `verify-screen` compares two decoder eras until the tag reaches `main`.

Mine: **the message gives the bundles as "0/1 and 10/11", which is the `is_build` ordinal, and `authored/screen_names.json` is keyed by PAK ENTRY** — in entry space 10 and 11 are `palogo_sqex` and `palogo_gamearts`, the splashes.

## New ask, 2026-08-31 — derived from HANDOFF (today's blend-mode delivery), port `HEAD` `0a054d6`
## ✅ ANSWERED and TAKEN — the four EXTRAS elements, and a fifth. Port `HEAD` `49a6333`
`ptframe4`, `pteff21`, `pteff22`, `pteff23` **and `pteff10`** are additive on
EXTRAS, measured. They were in a draw all along: the vertex dump was capped at two
quads and the batch holds six, so four were dropped **with a well-formed log line**.
Adopted — EXTRAS whole-screen residual **1.97 → 0.63**, `ptframe4` 31.90 → 1.14.
See `DECISIONS.md` for the `pteff10` metric split and why I took it anyway.
## New ask, 2026-08-31 — three, derived from today's completed blend delivery, port `HEAD` `49a6333`
**1. Is `pteff10` additive on the MAIN MENU too?** It is measured additive on
EXTRAS. The main menu has an unidentified additive draw of **819.2 × 720** — the
exact size `pteff10` is drawn at (409×144 at its resting 200 %×500 %), and the same
size as the draw now identified as `pteff10` on EXTRAS. **I have not adopted it**:
that identification would be mine, and their own corrected coverage table still
lists `pteff10` as uncovered on the main menu. The improved matcher against the
existing main-menu log should settle it at no capture cost.
**2. The sweep strips' vertex alpha ramp.** They are additive and their vertex
alpha ramps across the sweep, and the leaf group **does** run on the menu — which
refutes this port's scoping. The port has neither the blend nor the ramp on the
leaf path, so switching the loop on today makes the port more correct in behaviour
and visibly worse against the capture. **What is needed is the ramp**: what the
per-draw alpha is as a function of sweep position.
**3. Does `kind & 0x2` belong in the exporter?** Their focusable-flag result (0
violations in 15 493 entries, 24 paks) implies `ptbtn00` on the PRESS Ⓐ plate —
`0x73002` in my export — is focusable, and my exporter classifies it `unknown`
rather than `button`. That is a **decode**, so consuming it is legitimate; I am
asking rather than taking because it changes an exporter classification that other
things read, and `0x3000` (817 elements disc-wide, button-shaped and *not*
focusable) is exactly the trap a looser rule would fall into.
**Four elements on EXTRAS are in no draw capture: `ptframe4`, `pteff21`, `pteff22`,
`pteff23`. What blend mode do they use?**

## P0 — the exporter, 2026-08-28
@@ -16292,3 +16295,94 @@ per-element facts. No button appears in the EXTRAS draw log at all — the
generalisation comes from `ptbtn01f` on the main menu. It is very likely right, and
the port depends on nothing that would break if it were not; I raise it only
because it is the same move the document tells its reader not to make.
## EXTRAS is complete: 1.97 → 0.63, and the two metrics disagree about it
The four elements I reported as absent from every draw were in a draw all along.
The vertex dump was capped at 8 vertices — two quads — and the additive batch holds
six, so the log printed `pteff20` and `ptframe3` and dropped the other four **with
a well-formed line and no ellipsis**. Cap raised, screen recaptured, all six named.
📌 A truncation that leaves no mark is the same failure class as my MIX-default
material: the run completed, the output parsed, and the answer was wrong.
`ptframe4`, `pteff21`, `pteff22`, `pteff23` and **`pteff10`** are additive on
EXTRAS. Transcribed.
| EXTRAS element | before | after |
|---|---|---|
| **`ptframe4`** | 31.90 (16.19×) | **1.14** (1.81×) |
| `pteff21` / `22` / `23` | 14.34 / 13.15 / 12.04 | 0.79 / 0.72 / 0.73 |
| `ptframe3` | 7.97 | 1.26 |
| **whole screen** | **1.97** | **0.63** |
### 🟡 Their `pteff10` flag, tested — and the answer is "both metrics, opposite ways"
They flagged it before I could adopt it: *"you measure it nearly exact under
alpha-over and the game draws it additive… it is the one row your renderer does not
independently corroborate."* Tested by holding `pteff10` at alpha-over with every
other element additive:
| | tone-corrected \|resid\| | raw RMSE |
|---|---|---|
| `pteff10` **additive** (as measured) | **0.630** | 12.91 |
| `pteff10` alpha-over (as the port had it) | 1.704 | **9.98** |
🔴 **They disagree, and the reason is not subtle.** The port already renders
**+8.50 levels brighter than the capture** on this screen *before any of this*
(render 35.16 against capture 26.65); additive adds 3.85 more. Raw RMSE is
dominated by that pre-existing offset, so it punishes any added light regardless of
whether the light is correct. The tone-corrected number, which removes exactly that
offset, says additive is **2.7× better** — and `verify-capture`'s differing region
halved, 0.07 % → 0.03 %.
✅ **The measurement wins and I have adopted it**, because it is measured off the
game and the structural metric agrees. ⚠️ **But `extras` raw-RMSE went 11.43 →
12.88 and I am not hiding that.** By the tool's own header — *"RMSE is reported and
is NOT a target… what finds a real defect is the DIFFERING REGION"* — the screen
improved. The +8.50 offset is a separate, older question and **I am not correcting
it**: I established weeks ago that I cannot say which side's tone is wrong.
## 🔴 Refuted: my kind census was a two-screen generalisation, one message after I criticised theirs
I reported *"every sprite decoration is `0x0` and every button `0x3002`"* as an
independent confirmation. They refuted it: `kind & 0x2` is the focusable flag (0
violations in 15 493 entries across 24 UI paks), while `kind == 0x3002` catches 778
of 1 062 focusable elements and **misses 284**.
**My own export contained the counter-examples the whole time:**
| element | `kind_raw` | what my exporter calls it |
|---|---|---|
| `press_start` / **`ptbtn00`** | **`0x73002`** | `unknown` — *not* `button` |
| `title` / `ptlogoall_eff`, `ptlogoall_eff2` | **`0x3000`** | `unknown` — looks like a button, is not focusable |
| `title` / `ptlogo1`, `ptlogo2` | `0x4` | `unknown` |
📌 **This is exactly the move I had just objected to in their page** — *"every
button" is a class generalisation in a document that tells its reader not to make
them* — and I made mine one message later, from two screens, and called it a
confirmation. The census was **true where I looked** and false one build over.
⚠️ **It has a consequence, not just a lesson.** `ptbtn00` on the PRESS Ⓐ plate is
focusable by their rule and my exporter classifies it `unknown`. Filed.
## 🔴 Refuted: the sweeps DO run on the menu, and my instrument was measuring my own renderer
`loop_leaf_on_screens` scopes leaf-looping to the title, partly on a phase sweep of
mine that I re-ran only last iteration and reported as *strengthened*. Their draw
log retains NDC, and settles it directly: **both strips overlap the screen in every
captured frame on the main menu, stepping ~0.03 NDC per frame in opposite
directions, with their vertex alpha ramping** — two sessions, different phases.
🔴 **"The game does not draw them here" is no longer available to me.** What my
phase sweep actually measured is that *the port's version of the sweeps* makes the
match worse — which is a statement about my rendering of them, not about whether
the game runs them. **A best-match argument for an absence cannot distinguish "not
there" from "there and drawn wrong",** and I had that caveat written down and still
read the result as being about the game.
⚠️ **Not flipped yet, deliberately.** The strips are additive *and* their vertex
alpha ramps across the sweep; the port has neither of those right for the leaf
path, so enabling the loop today would make the port more correct in behaviour and
visibly worse against the capture. That trade needs the ramp first, and it is
filed. What has changed today is the *claim*: **the port is wrong here, and says
so.**
