+### The voice reaches the output, and a null control says so quantitatively
+
+`+ voice ADV` in the log proves only that `play_voice` found a stream and called
+`play()`. Whether the audio arrives at the Master bus is a different question,
+and `docs/port/AUDIO-VERIFICATION.md` §2 exists because it is.
+
+The control needed **no test-only code**: MODDING rule 4 already shadows any
+exported asset by path, so 140 s of silence dropped at
+`data/mods/audio/voice/ADV.ogg` mutes the dialogue and changes nothing else. Two
+`--boot --skip-at=25 --audio=…` runs, then `astats` over the same 14 s of movie:
+
+| | peak | RMS | 
+|---|---|---|
+| `ADV.ogv`'s own audio (the bed) | −6.239 | −24.941 |
+| the exported voice alone | −7.614 | −27.965 |
+| **run with the voice muted** | **−6.251** | **−25.126** |
+| **run with the voice playing** | **−5.415** | **−22.913** |
+
+The muted run reproduces the bed to **0.01 dB peak / 0.19 dB RMS**, which is what
+makes the other row worth reading. And the mixed run is not merely *louder*: two
+incoherent sources at −24.941 and −27.965 dBFS predict a sum at **−23.184**, and
+the run measures **−22.913** — **0.27 dB** out. The voice is in the mix, at the
+level its own file says it should be.
+
+⚠️ **Under the Dummy driver.** Per AUDIO-VERIFICATION, *"recorded under a dummy
+driver"* is a weaker claim than *"heard"*, and no measurement here says the
+recording is the **right** dialogue for this cutscene — only that the file the
+exporter resolved is the one reaching the output at the expected level. The two
+runs are also not sample-aligned (they differ by 1.7 s of wall clock), which is
+why the `RMS trough` column is omitted: it moved by 40 dB between runs on window
+placement alone, and peak and RMS are the two numbers that survive that.
+
+### Ⓐ *does* skip the intro in this build, so the play-test's report is not this bug
+
+`--skip-at=25` on a `--boot` run: `video skipped at 25.02 s`, `video ended at
+25.02 s`, title at 25.02 s. The press goes through `Input.parse_input_event` and
+arrives at `_unhandled_input` exactly as a pad's would, so **the wiring from press
+to skip is live**. What that does not cover is a real key event from a focused
+window, which is the difference between this run and the human's — and, separately,
+**whether the game permits skipping an attract movie at all** is HANDOFF Q9 and
+still 🟡. If the answer is no, this path is deleted rather than debugged.
