 |---|---|---|
 | **H1** | **Does a held direction REPEAT in the menus, and at what rate?** Initial delay and repeat interval, for the d-pad and for the left stick separately if they differ. | Behavioural. The port now does **one step per deflection** — `authored`, and deliberately the conservative half: it cannot run away and it invents no rate. If the game repeats, a human will feel it as *"I have to flick it again"*. |
 | **H2** | **The splash blur/fade-in does not match the game.** A human watching both says the game's is **more pronounced** than the port's. | Needs a capture of the publisher/developer splash across its fade, at a known frame cadence. The port's ramp comes from the declared keyframes; whether the game applies a **blur** on top — and whether what we read as a fade is one — is not answerable from the export. |
+| **H3** | **The `PRESS Ⓐ` plate arrives LATE.** The port raises it at `t=236`, derived `238 − 118 = 120 units = 2.000 s`. | 🟡 **Half of this may be the port's, and that half must be settled here first.** Three candidate causes: the **unit→seconds constant** (Decoder's), the **clock origin** — do builds 2 and 4 really start together? — and **`rest.t`** (both ours). `REFUTED.md` records that believing `rest.t` already put a plate **3.97 s late** once. Establish which half it is *before* asking, and say how. |
 
 **On H2, three things the port can say that narrow it**, none of which settle it:
