# The oracle frames — what to verify a render against

**These are framebuffer captures of the real game running under Xenia Canary.**
They are the reference. `sylpheed-cli screen render` is **not** — Reborn is a GUI
explorer and extraction CLI built to check that our *decoding* is right, and it
may very well be wrong. Where a render and a capture disagree, the capture wins,
and the render is the thing to go and fix.

⚠️ Two renderers agreeing proves nothing: they share our assumptions. This corpus
has been bitten by exactly that three times — the dropped `pteff05` background,
the scale-0 rect, and `rest()`. Each was invisible to any render-vs-render diff
and visible immediately against a capture.

## The frames

All are **1279×675**, top-left aligned, cropped to the game surface by the
screenshot tool (the guest renders 1280×720; the missing row/column is the crop,
not a scale).

| screen | capture |
|---|---|
| publisher splash (SQUARE ENIX) | [`title-builds/live-splash-publisher.png`](title-builds/live-splash-publisher.png) |
| developer splash (GAME ARTS / SETA / anima) | [`title-builds/live-splash-developer.png`](title-builds/live-splash-developer.png) |
| title, **without** the `PRESS Ⓐ` plate | [`title-builds/live-title-build4-no-plate.png`](title-builds/live-title-build4-no-plate.png) |
| title, **with** the plate | [`title-builds/live-title-press-a.png`](title-builds/live-title-press-a.png) |
| main menu | [`title-builds/live-main-menu.png`](title-builds/live-main-menu.png) · [`main-menu-oracle.png`](main-menu-oracle.png) |
| main menu, **`OPTIONS` focused** | [`title-builds/live-main-menu-options-focused.png`](title-builds/live-main-menu-options-focused.png) |
| `EXTRAS` | [`title-builds/live-extras.png`](title-builds/live-extras.png) |
| title (alternate) | [`title-screen-oracle.png`](title-screen-oracle.png) |
| a screen transition, 13 frames | [`transitions/transition-filmstrip.png`](transitions/transition-filmstrip.png) + [`transition-luminance.csv`](transitions/transition-luminance.csv) |

The **focused** pair is the useful one for button states: the same screen with a
different button highlighted, so the difference isolates what focus changes.

## ⚠️ Before you compute an RMSE against one

* **They are not gamma-neutral.** `capture ≈ 255·(render/255)^γ` with γ ≈ 1.34–1.49,
  and that is a ramp **the game installed**, not a capture-path artefact. So RMSE
  against these has a floor and chasing it below that floor is chasing the ramp.
  [`../structures/ui-render-tone-curve.md`](../structures/ui-render-tone-curve.md)
* **Geometry is sound**: cross-correlating a render against `live-main-menu.png`
  over ±6 px puts the best alignment at exactly (0,0), correlation 0.9466. So a
  positional disagreement is real, not a crop artefact.
* **A capture is one moment.** Several of these screens are still animating; the
  title's two `ptloop` sweeps move continuously. Compare settled poses, or
  compare regions you know are at rest.

## What is NOT here

No capture of the interactive title reached mid-run without a pad press — three
runs across two locales and two launch paths never reached it in ~35 minutes.
See [`../capture-harness-status.md`](../capture-harness-status.md). And no
`GP_READY_ROOM` capture; S1 ruled it out of scope.
