 **If parent scale gates the leaf it is a 0.95 s flash; if the leaf runs free it
 spins for 16 s.** Nothing on the disc chooses, `title_jp` has no oracle capture,
 and the Japanese-locale capture MISSION has parked is what would settle it.
+
+## The 11.5 px was the fit's resolution, and the lesson inverts
+
+The Decoder closed it **by adding observables, not by tuning** — the vertex
+buffer carries positions *and* colours at the same instant, so all four
+quantities must agree on one `t`:
+
+| observable | solved t | precision |
+|---|---|---|
+| quad A x | **357.88** | ±0.12 units |
+| quad B x | **357.58** | ±0.12 units |
+| quad A alpha | 355.75 | ±1.54 units |
+| quad B alpha | 354.09 | ±1.89 units |
+
+Alpha moves only 0.27–0.33 levels per keyframe unit, so **one byte of
+quantisation is worth 1.5–1.9 units, which at 4 px/unit is 6–8 px of sweep**.
+That is the whole of the 11.5 px. At t = 357.7 the centres land within 0.70 px
+and both alphas inside one level.
+
+⚠️ **The lesson is the earlier one inverted, and this is the half worth keeping.**
+Checking a wrong rule against alpha made it *look confirmed*. Here the same
+insensitivity **manufactured a residual that did not exist**. So an insensitive
+quantity does not merely fail to falsify — **it invents error.** Solve on the
+fastest-moving field; check the slow one; never the reverse.
+
+I was already looking for a pivot rule to explain 11.5 px when they wrote. There
+was nothing to find.
+
+### Refutation attempt — the pivot claim, checked here and survived with a nuance
+
+They state the leaf pivot is (200, 90) on a 399×180 sprite, *"the pivot is the
+centre, so rotation displaces it by nothing."* Checked against my own export:
+pivot **[200, 90]**, sprite **399×180**, true centre **199.5, 90**.
+
+✅ Survives. ⚠️ With one correction of no consequence: the sprite is **odd-width**,
+so the pivot is the centre to within **half a pixel**, not exactly. Against their
+−0.70/−0.48 px agreement that changes nothing, and it is worth stating only
+because "displaces it by nothing" is the kind of sentence that later gets leaned
+on for a sub-pixel claim.
+
+`verify-capture` now poses the title at **t=357.7** rather than 355: RMSE
+21.07 → **20.92**, differing 1.82 % → **1.81 %**. Marginal, and it is the right
+pose for a stated reason rather than a better number.
+
+### `ptlogo_eff2` is withheld for a better reason than mine
+
+I was withholding it out of caution about untested generalisation. The Decoder
+points out something stronger: **it is on `title_jp`, and MISSION §7 scopes out
+"localisation beyond English"** — so it is not a question the menu port has to
+answer at all, and the parked Japanese-locale capture does not need reviving on
+its account. `authored/rendering.json` now says that first and the undecidability
+second. **Widening scope to close a residual would have been the wrong trade**,
+and it is the human's call either way.
