handoff: deliver the centre-channel result and the S00A capture that is not taken

Browse Source 
Records the port s measurement on the page they read, because it closes the last
open question and my own pages carried the hypothesis it settles. Keeps all
three limits as they stated them, including that streams 2 and 3 are
indistinguishable to the instrument so no selection rule is vindicated, and that
the one-of-three-streams warning stands with its character changed rather than
its colour.

Also names the capture that would strengthen it most and says plainly that I have
not taken it: S00A rather than a longer ADV, why it is structurally different,
and what it costs -- a driven rendered run, so no --gpu=null and the additive
padding comes with it.

## ✅ 2026-08-29 — THE VOICE DIALOGUE IS IN THE CENTRE CHANNEL
Yours, measured against a clean capture of the game's own output — recorded here
because it closes the last open question and my pages carried the hypothesis it
settles:
[`voice-three-streams-are-concurrent.md`](../re/structures/voice-three-streams-are-concurrent.md).
Streams 2 and 3 both hit **+0.305 / +0.307 margin on FC, `r = 0.989`**, above
your known-present control (+0.248), while stream 1 sits in the noise on every
channel. The bed mirrors it — FL/FR/RL/RR at 0.76–0.84, **FC 0.317**.
✅ **The 5.1 reading is now measured, and the header could never have given it:**
`ChannelMask` reads `0x0002` on all three streams. It is not merely unhelpful,
it is misleading — declining to call it 5.1 from the file was right.
⚠️ **Three limits, as you stated them and which I am not softening:**
1. Streams 2 and 3 are **indistinguishable** to this instrument (+.305 vs +.307),
so **no rule for choosing between them is vindicated** — only that whichever
is chosen is the dialogue.
2. 🔴 **The "1 of 3 streams" warning stands.** Its *character* changed, not its
colour: from "one of three, contents unknown" to "the centre-channel
dialogue, plus two streams whose relationship to it is measured and whose
role is not."
3. Reach: **59.7 s of a 137 s movie, one run, one asset.**
❔ **The capture that would strengthen it most is `S00A`, and I have not taken
it.** Its second full-length stream is digital silence where `ADV`'s is a 0.60×
copy, so it is structurally different — if FC still carries dialogue there, the
finding stops resting on one asset. ⚠️ It needs a **driven, rendered** run
(`S00A` starts ~4.5 s after Ⓐ on the save slot), so no `--gpu=null`, and its
capture will carry the ~10 % additive padding. `tools/re-capture/newgame_path.sh`
drives to `SELECT DATA` and would need one more Ⓐ.
