Subject: [PATCH] Restore Yardline RC phone-controller bridge
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The 2026-07-23 deduped-Babylon rebuild (#27) fixed the missing cars but was
built from a source tree without the console embed bridge, so the phone fell
back to a d-pad and no input reached the car — the map and cars render but the
game is undrivable from a phone.

Restore the bridge without a rebuild (source lives in Artan0/razing, not here),
matching how BUILD.md already hand-patches this vendored bundle:

- index.html: inline bridge script that declares the phone pad per race phase
  (sc:controls), feeds sc:analog frames into the car, and routes sc:intent
  buttons (reset/powerup/pause, menu nav, results screen) — mirroring the
  original in-bundle bridge.
- assets/index-CSoa7UUc.js: expose the two runtime instances the bridge drives
  (window.__scInput = input controller, window.__scRace = race state machine).
- BUILD.md: document the patch and a post-rebuild check so it can't silently
  regress again.

+**Phone-controller bridge (patched 2026-07-24):** the source builds embed a
+bridge that (a) tells the console shell which phone pad to show per race phase
+via `postMessage({type:"sc:controls", …})` and (b) receives the phone's
+`sc:analog` driving frames + `sc:intent` button presses back. The 2026-07-23
+deduped rebuild came from a source tree WITHOUT that bridge, so the phone fell
+back to a d-pad and no input reached the car — the cars rendered but were
+undrivable from a phone. Restored here without a rebuild:
+- `index.html` carries an inline `<script>` bridge (mirrors the original:
+  per-phase `sc:controls`, analog → `setTouchDrive/Brake/Handbrake`, intents →
+  reset/powerup/pause/menu-nav).
+- `assets/index-*.js` is patched to expose the two runtime instances the bridge
+  drives: `window.__scInput=this` in the input-controller constructor and
+  `window.__scRace=this` in the race-state-machine constructor.
+
+After ANY rebuild, verify the bridge survives: `grep -c 'sc:analog' index.html`
+must be ≥1, and `grep -c 'window.__scInput=this' assets/index-*.js` must be 1
+(else re-apply, or — the proper fix — restore the embed bridge in
+`Artan0/razing` and rebuild, then drop the inline shim).

 ## Pruned for the console embed
 Full build ~138 MB (Downtown MegaKit + editor-only props). The console only plays
 the fixed `construction-loop` preset, so editor-only assets are pruned to ~64 MB.

+    <!-- Space Console phone-controller bridge. The 2026-07-23 Babylon rebuild
+         (dedupe fix for the missing cars) dropped the in-bundle embed bridge, so
+         the phone showed a d-pad and no input reached the car. This restores it
+         against two runtime handles the bundle now exposes on window
+         (__scInput = input controller, __scRace = race state machine). It mirrors
+         the original: declares the pad layout per race phase, feeds analog frames
+         into the car, and routes discrete intents. See BUILD.md. Remove this once
+         the source repo (Artan0/razing) rebuilds with the bridge included. -->
