re: 125 percent is not the only odd scale, and ptlogo_eff2 is a pop not a steady state

Browse Source 
Refutes a DECISIONS claim and decodes the element the port withheld on my say-so.

The claim that title_jp s ptlogo_eff2 at 125 percent is the single drawn element
in the whole export at a scale that is not a whole multiple of 100 percent rested
on a census of PARENTS only. Opening the 45 leaves as well finds thirteen
distinct non-whole-multiple scales -- 75, 96, 99, 101, 103, 112, 125, 150, 204x208,
210x220, 250, and the 75x100 / 96x100 / 99x100 pairs -- with 125 among the rarest
at two occurrences. ptlogo1 and ptlogo2 carry 101/103/112 on the ENGLISH title
too, so it is not a Japanese-build peculiarity. The claim s real content was "the
only one the port draws", which is about the export s element set rather than the
disc.

And ptlogo_eff2 is decoded. The 125 percent lasts 57 units, about 0.95 s -- a
scale-0 to 125 to scale-0 flash between t=50 and t=107, a transient rather than a
steady state, which is why it looked anomalous in a census of resting poses. The
leaf draws at 100 percent as two superimposed copies of the same sprite at alpha
160 and 80, each rotating a full 360 degrees over 960 units: a slow double-layered
spin, 16 s per revolution.

This is exactly the case the ptloop rule could not separate. There the parent had
expired so leaf-wins and parent-ignored were indistinguishable; here the parent
carries real geometry including a scale that reaches zero twice. If parent scale
gates the leaf the spin is a 0.95 s flash; if the leaf runs on its own timeline it
spins for 16 s. Nothing on the disc chooses between them, and title_jp has no
oracle capture, so it is undecodable in this container -- the port is right to
withhold it, and the Japanese-locale capture MISSION has parked would settle it.

## 🔴 Refutation — "125 % is the only non-whole-multiple scale" is WRONG, and by a lot
`DECISIONS.md` records `title_jp`'s `ptlogo_eff2` at 125 % as *"the single drawn
element in the whole export at a scale that is not a whole multiple of 100 %"*.
That census was over **parents only**. Opening the 45 leaves as well
(`--example scale_census`, output at
[`data/ui-scale-census-with-leaves.txt`](../data/ui-scale-census-with-leaves.txt)):
| scale | count | where |
|---|---|---|
| **75,75** · **96,96** · **99,99** | 4 each | `pgloading_loop4.rat` on all four loading screens |
| **75,100** · **96,100** · **99,100** | 4 each | `pgloading_line.t32` |
| **101,101** · **103,103** · **112,112** | 12 each | `ptlogo1` / `ptlogo2`, entries 4 **and** 7 |
| **150,150** | 28 | `pgloading_loop1.rat` |
| **204,208** · **210,220** | 1 each | `ptlogo_eff2` … no: `ptlogoall_eff.t32`, entry 4 |
| **250,250** | 2 | `pgloading_loop5.rat` → **LEAF** `pgloading_ring.t32` |
| **125,125** | **2** | `ptlogo_eff2.rat`, entry 7 |
**Thirteen distinct non-whole-multiple scales, and 125 % is among the rarest at
2 occurrences.** `ptlogo1`/`ptlogo2` carry 101/103/112 on the **English** title
too, so this is not a Japanese-build peculiarity. ⚠️ The claim's real content was
"the only one *the port draws*", which is a statement about the export's element
set, not about the disc.
## ✅ And `ptlogo_eff2` itself is decoded — the 125 % is a POP, not a steady scale

* The **125 % lasts 57 units (~0.95 s)** — a scale-0 → 125 % → scale-0 flash
between t=50 and t=107. It is a transient, not a steady state, which is why it
looks anomalous in a census of resting poses.
* The **leaf draws at 100 %**, as **two superimposed copies** of the same sprite
at alpha **160** and **80**, each rotating **a full 360° over 960 units** — a
slow double-layered spin, 16 s per revolution at 60 units/s.
🔴 **And this is exactly the case my `ptloop` rule could NOT separate.** There the
parent had expired (alpha 0, no sprite) so "leaf wins" and "parent ignored" were
indistinguishable. Here the parent carries **real geometry** — a scale that
reaches 0 twice. If parent scale gates the leaf, the spin is a 0.95 s flash; if
the leaf runs on its own timeline, it spins continuously for 16 s. **The two
readings differ enormously and nothing on the disc chooses between them.**
❔ **Undecodable here, with reach:** `title_jp` has **no oracle capture**, so this
cannot be adjudicated in this container at all. The port is right to withhold it.
A capture of the Japanese title would settle it — and that is the same
Japanese-locale capture MISSION has parked as 🟡 since 2026-08-29.
