fix(components): portal hosts are hit-transparent — the constant-33 hardware bug - #213
Merged
Conversation
…ardware bug Every touch on real Vita hardware resolved to ONE node — the TextField's Portal host — killing list pans and field taps while the OSK (modally exempt) kept working. The host is an explicit full-screen absolute box in the overlay layer; #209 marked the overlay ROOT hitPass but every portal host inside it was another full-screen pure container that still claimed every bounds hit. Why no rig caught it: the pocket-youtube sim's vendored wasm was STALE (predating op 42), so its journeys silently exercised the ink-query FALLBACK, not the fact path; the Vita3K suite's only touch spec drove OSK keys — overlay content, immune. The on-device svc diagnostic (every touch-down reporting x,y,hit) showed the constant node id across the whole screen; rebuilding the vendor wasm reproduced it in the sim in one probe. - Portal host + the TextField dock wrapper: hitPass (pure plumbing never claims; a modal scrim is portal CONTENT and keeps blocking). - tests/portal-hit.test.ts: the REAL-core mount test mock hosts cannot express — a mounted empty-chrome Portal must not swallow bounds hits (fails without the fix, registered in the chain). - golden-specs: im-rowtap made permanent — app-layer tap-through-the-stack coverage on BOTH oracles (web + Vita3K), the hole this bug lived in. Validated: canonical chain 0 fail, 54 web goldens, im-rowtap + im-touch Vita3K byte-exact. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

The first real-hardware regression of the phase-2 touch program, found live on a Vita and diagnosed over the svc channel.
The bug
Every touch on the device resolved to one constant node id (33) — the TextField's Portal host: a full-screen absolute box in the overlay layer. #209 made the overlay ROOT
hitPass, but portal hosts inside it are full-screen pure containers too. Result: list pan dead, field tap dead, OSK alive (modally exempt).Why every rig missed it
