+## ✅ 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 Ⓐ.
