…tion One-shot feasibility desk study: could Buiy ever target native iOS/Android? Maps the current stack (render/GPU, windowing+input+lifecycle, text+IME, a11y, platform-services+build, operational) against a native mobile port, then validates the load-bearing claims against current upstream sources. Verdict: feasible, unbuilt-not-blocked. The render/text/layout core is already target-agnostic (wgpu auto-selects Metal/Vulkan, shaders are uniformity-clean, fonts+shaders embedded), and the wasm port de-risked the same portability work. Mechanical items are minor (arboard cfg gate, band.wgsl 16-attr fold, Rgba16Float GLES gate, first-tap activation, mobile scaffold); the two hard blockers (robust soft-keyboard/IME, OS a11y) are upstream winit/Bevy-gated; the sleeper is foreground-idle battery drain from Bevy's default continuous redraw (a one-liner that maps onto MVU dirty-state). Validation (6-agent web fact-check + prior-art scan) overturned two first-pass claims and is recorded transparently: winit DOES raise the mobile soft keyboard (set_ime_allowed, just Android-flaky), and accesskit Android multiplexing predates 0.33 (opt-in feature Bevy doesn't enable). Full CONFIRMED/REFUTED ledger with source URLs is in the report. - Adds docs/reports/2026-07-11-native-mobile-feasibility.md (report, Date/Status header per organizing-buiy-docs convention). - Adds the catalog entry at the top of docs/README.md ### Reports. - §6 maps the relevant prior-art/ folders; §8 flags slint-mobile / bevy-mobile as researching-prior-art promotion candidates (flagged, not spawned). Docs-only; no code changes. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

docs/reports/2026-07-11-native-mobile-feasibility.md(report) + the catalog entry at the top ofdocs/README.md ### Reports. Docs-only; no code changes.Produced by two multi-agent workflows: a 6-dimension subsystem probe (render/GPU, windowing+input+lifecycle, text+IME, a11y, platform-services+build, ecosystem) with accuracy + completeness critics, then a 6-agent validation pass (5 web fact-checks + 1 prior-art corpus scan).
Verdict
Feasible — unbuilt, not blocked. The render/text/layout core is already target-agnostic (wgpu auto-selects Metal/Vulkan, shaders uniformity-clean, fonts+shaders embedded), and the wasm port de-risked the same portability work.
