MoUI Cross-Platform Verifiability Declaration
Version: 2026-08-29 Every claim below can be independently verified through its referenced CI workflow, run record, artifact name, or test file.
| Tier | Canonical routes | Gate |
|---|---|---|
| Tier 1 | macOS Skia, Web wasm-gc WebGPU (Canvas2D fallback) |
Blocking: PR build/test, daily presentation, and release evidence |
| Tier 2 | Windows Skia, Linux Skia |
Blocking: L0-L2 and first frame; complete L3 may remain partial |
| Tier 3 | macOS WGPU (CoreText, Cosmic fallback), Windows WGPU (DirectWrite, Cosmic fallback), Linux WGPU (Fontconfig, Cosmic fallback), Android window-hosted Skia, iOS window-hosted Skia, HarmonyOS window-hosted Skia, macOS Sun, Windows Sun, Linux Sun, WeChat Skyline Canvas2D |
Non-blocking: scheduled/manual build, run, and evidence |
Tier, L0-L3 evidence, and product_class/ready are independent. Source: checks/platform-matrix.json; actual observations remain in checks/platforms/*.json.
Product Commitment Matrix (product_class)
This table is the single public source of truth for whether a platform can serve
as a product mainline. It differs from the mainline/diagnostic engineering
gates in docs/maintenance.md: those define the routine check.sh scope, not
OS product completeness.
| Platform | product_class |
Semantics of ready (host API) |
Evidence summary | Not yet committed |
|---|---|---|---|---|
| macOS | committed | Usable as a product mainline | L0–L2 PR gates + L3 platform runtime passed (checks/platforms/macos.json) |
— |
| Web | committed | Usable as a product mainline | Daily wasm-gc + browser WebGPU; checks/platforms/web.json runtimeL3=passed |
— |
| Windows | committed | Usable as a product mainline | L0–L2 PR/real Skia; matching-host Win32 runtime smoke + Showcase first-frame (checks/platforms/windows.json runtimeL3=passed, 2026-08-29, ADR 0031) |
— |
| Linux | committed | Usable as a product mainline | L0–L2 PR/real Skia; matching-host Wayland runtime smoke + Showcase first-frame (checks/platforms/linux.json runtimeL3=passed, 2026-08-30, ADR 0032) |
— |
| Android | experimental | ready=false: the window-hosted template + session compile and host-sim tests pass, but no development/demonstration usability or product commitment is made; status=experimental |
HostCmd host-sim and MoUI adapter tests pass |
Matching-device presenter/service evidence; GPU seven-gate claim; usability commitment |
| iOS | experimental | Same as above | HostCmd host-sim and MoUI adapter tests pass |
Matching simulator/device presenter and VoiceOver evidence; GPU seven-gate claim; usability commitment |
| HarmonyOS | experimental | Same as above | HostCmd host-sim and MoUI adapter tests pass |
Signed-device presenter/service evidence; GPU seven-gate claim; usability commitment |
| WeChat Mini Program | experimental | ready=false: the window-hosted Canvas 2D session compiles, but no development/demonstration usability or product commitment is made; status=experimental |
Canvas 2D renderer and wasm-gc build pipeline compile; Skyline project template is staged | Real Mini Program pixel smoke; touch event verification; wx API service integrations; usability commitment |
Linux RISC-V64 Architecture Variant
Linux RISC-V64 is recorded as linux-skia-riscv64 under
checks/platform-matrix.json, not as a new canonical platform route. The
variant targets riscv64-linux-gnu, is Tier 3 and experimental, and keeps
ready=false while the matching-device Wayland path is unverified.
| Evidence | Initial contract | Promotion boundary |
|---|---|---|
| L0 | Cross-built examples/showcase/linux_skia ELF64 RISC-V |
Locked sysroot, Zig wrapper, and ELF report |
| L1 | Cross-build package/link checks | Target GLib/Wayland/fontconfig pkg-config and native link success |
| L2 | QEMU offscreen Skia Raster renderer and text/emoji smokes | Real pixel markers, async second frame, and SkParagraph output |
| L3 | pending |
Matching RISC-V64 Wayland device first frame, input, IME, clipboard, and services |
The independent evidence file is
checks/architecture-evidence/linux-skia-riscv64.json. QEMU L2 evidence does
not promote checks/platforms/linux.json or the Linux Wayland runtime claim.
Two Prohibited Misstatements
- Do not state “all six platforms are product-ready / all L3 checks are green.”
- Do not state “the three embedded runtime backends are entirely nonfunctional / lifecycle glue is unwired / only a Counter app exists.” The embedded runtime backends and IME/clipboard/a11y channels exist; the gap is in the evidence loop and promotion, not an absent host path.
Do Not Conflate the Three Status Sets
| Dimension | Meaning |
|---|---|
Host availability (ready) |
true only when development/demonstration can rely on the window-hosted template + MoUI session (Linux-aligned: implementation complete and usable); false for experimental platforms until matching-device evidence lands |
Runtime evidence (status / smoke) |
Matching-host observation: passed / partial / packaging-only; mobile product_class experimental is deliberately below runtime_partial |
| Product-completeness commitment | All L3 checks green + actualPresenterRoute verified + GPU seven-gate claimed |
Mobile product_class experimental means: code paths compile and host-sim
tests pass, but no development/demonstration usability or product
commitment is made until matching-device presenter/service evidence is
recorded. It is a downgrade from the previous runtime_partial claim
(see ADR 0021); it does not claim the backends are nonfunctional.
The structured status source is
checks/platforms/{macos,windows,linux,web,android,ios,harmonyos}.json.
Do not raise runtimeL3 / actualPresenterRoute without new evidence.
The GPU product default (NativeGpuPlatform::gpu_promoted=true) and the
a seven-gate quality claim are tracked separately; see ADR 0006.

I. Declaration Entity
| Item | Value |
|---|---|
| Project name | MoUI — cross-platform MoonBit UI framework |
| Repository | https://github.com/wzzc-dev/MoUI |
| Main branch | main |
| Declaration scope | Framework core + rendering pipeline + platform backends + text system + example applications |
| Rendering backends | Skia Raster Native (mainline), WebGPU wasm-gc (Web), WGPU (experimental; engineering gate diagnostic) |
II. Target Platforms and Evidence Levels
| Level | Definition | CI trigger | Host requirement |
|---|---|---|---|
| L0 — Compile/API | Successful compilation, stable public API, formatting compliance | Every PR (ci.yml) |
None (fallback-safe build) |
| L1 — Algorithm/Protocol | Package tests pass without a real renderer | Every PR (ci.yml) |
None |
| L2 — Runtime Behavior | Pixel-level rendering verification with real Skia/WebGPU | Every PR (moui-renderer-real-skia-ci.yml) |
Matching host |
| L3 — Full-Platform Evidence | Full-platform runtime behavior, including first-frame presentation, IME, clipboard, and window services | Scheduled + manual trigger | Matching host (Wayland/MSVC/AppKit) |
Evidence Criteria
- L2 renderer proof and L3 platform-runtime proof are recorded separately. A successful real-Skia render does not mean platform windows, IME, clipboard, accessibility, and other services have all passed.
- First-frame/Wayland evidence in L3 proves only that the corresponding platform route can present its first frame on a matching host. Describe a platform runtime as fully passed only when observations for IME, window services, input, clipboard, and similar capabilities also have matching-host logs.
- The “current” status on this page is based on the most recent verifiable successful workflow run. Historical failed or partially successful runs may provide diagnostic context, but must not override newer successful evidence.

Windows L3 Evidence Record
Windows platform-runtime evidence was captured on 2026-08-29 on a Windows matching host (MSVC 2022, Windows 10+ deployment floor). The full chain:
# 1. window repository: matching-host CI branch + runtime smoke transcript
bash window/scripts/capture_moui_runtime_evidence.sh windows \
--log <moui>/artifacts/platform-evidence/windows/moui-windows-runtime.log
# 2. MoUI Showcase first-frame presentation
bash scripts/windows-platform-evidence.sh
The runtime transcript satisfies the check_moui_runtime_log.sh windows
contract: surface probe, nonzero HWND/HINSTANCE with raw display/window
identity preserved, monitor/current-monitor probes with native ids, cursor
Icon(Text), the IME probe line enabled=true hint=true surrounding=true cursor=true updated=true updated_hint=true updated_cursor=true disabled=true,
resize delivery with pre_present_notify redraw, pointer and
keyboard key=a / IME text=a delivery before ready, and the
ready → destroy requested → destroyed → finished teardown sequence. Raw
transcripts and the preflight/summary logs are kept under
artifacts/platform-evidence/windows/ (generated evidence stays out of git).
Prerequisites: Windows MSVC 2022 toolchain + vcpkg zlib + a real Skia
provider (release cache is resolved automatically from
moui_skia/skia-provider-lock.json).

Linux L3 Evidence Details
The moui-linux-platform-evidence.yml CI workflow runs every Monday at 05:17 UTC:
workflow: MoUI Linux Platform Evidence
environment: ubuntu-24.04 + Weston headless + Wayland
证据制品: moui-linux-platform-evidence
├── linux-platform-evidence-preflight.log
├── linux-skia-first-frame.log
├── linux-platform-evidence-summary.log
└── weston-headless.log
Most recent successful run: GitHub Actions Run
28889055278, commit
8a054c5914adbfa34a6943570c1ceb01cc603ef5.
The evidence script uses the dedicated
moui_tests/tester/linux_skia_first_frame_smoke test program (similar to macOS
moui_tests/tester/macos_skia_first_frame_smoke), hard-coded with
first_frame_smoke_auto_exit=true; it exits automatically and prints a marker
after presenting the first frame. That run proves the Linux Wayland + Skia
first-frame route.
Code-level service completeness: the Linux backend is now fully wired—clipboard
(text + image dynamic buffer + GTK fallback), file dialog (portal + zenity),
directory listing (@fs.read_dir), text/binary file I/O, open URL (portal +
xdg-open), system theme, native menus (zenity + kdialog), IME, drag-drop, AT-SPI
accessibility, GLib timer, client-side decorations, multi-window, platform-view
plugins, and async image loading (pthread + Skia decode). readiness() is marked
ready: true with blocked_by: [].
WSL2 Validation Results (2026-07-11)
End-to-end runtime-evidence capture for the Linux backend was performed in a WSL2 + WSLg (Debian 13 on Windows) environment:
bash window/scripts/capture_moui_runtime_evidence.sh linux \
--log artifacts/platform-evidence/linux/moui-linux-runtime.log
Passed checks:
- ✅ Wayland surface/handle/probe: all operate normally (
wl_display,wl_surface,xdg_surface, andxdg_toplevelare all nonzero) - ✅ Present:
present result=0 - ✅ Cursor:
Icon(Text) - ✅ Resize + repaint: requested 400×240 → actual 320×180, with
pre_present_notifyconfirmation - ✅ IME probes: all 8 fields passed!
enabled=true hint=true surrounding=true cursor=true updated=true updated_hint=true updated_cursor=true disabled=true - ✅ Clipboard data device:
clipboard=true clipboard_roundtrip=true drag_drop=true - ✅
check_ci.shCI check passed
Checks not passed (due to non-interactive WSL2 environment constraints):
- ❌
pointer=false— no mouse events are injected automatically - ❌
keyboard=false— no keyboard events are injected automatically - ❌
current=false(monitor) — the window did not receive focus - ❌ Destroy sequence incomplete — the process exited after timeout
Conclusion: The IME protocol is functionally complete in WSL2/WSLg; all IME
probe fields passed. A complete L3 platform-runtime pass still requires running
with WINDOW_MOUI_LINUX_REQUIRE_INPUT=1 on a real Wayland desktop (Ubuntu
24.04+), where an operator provides actual keyboard input (for example, pressing
a) and a mouse click while the smoke-test window has focus to obtain pointer/
keyboard evidence.
Complete IME runtime evidence still requires a matching-host Wayland execution
of capture_moui_runtime_evidence.sh linux.

VI. Missing Evidence and Completion Plan
6.1 Windows L3 — Platform Runtime ✅ Completed (2026-08-29, ADR 0031)
| Item | Status | Evidence |
|---|---|---|
| Showcase Windows first-frame log | ✅ Completed | scripts/windows-platform-evidence.sh → MOUI_FIRST_FRAME_EXIT=1 moon run examples/showcase/windows_skia --target native on the matching MSVC host; marker verified, showcase_exit_status=0 |
| Windows IME / platform-service runtime observations | ✅ Completed | window/scripts/capture_moui_runtime_evidence.sh windows transcript accepted by check_moui_runtime_log.sh windows (IME 8-field probe, pointer/keyboard/IME text delivery, teardown sequence) |
| Windows status-manifest update | ✅ Completed | checks/platforms/windows.json runtimeL3=passed + checks/platform-matrix.json productClass=committed (ADR 0031) |
Note: the earlier "Markdown Editor Windows first-frame log" completion item is
obsolete — the Markdown Editor example has no Windows entrypoint; the Showcase
route is the canonical Windows presentation evidence. The retired
platform-runtime-evidence.json manifest (removed in 7b48bd5e) has been
replaced by the structured checks/platforms/*.json records.
6.2 Linux L3 — Complete Platform Runtime
| Missing item | Completion action | Prerequisites | Estimated effort |
|---|---|---|---|
| Linux first-frame / Wayland route log | scripts/linux-platform-evidence.sh |
✅ Passed (CI Run 28889055278; local WSL2/Wayland 2026-07-11) | ✅ Completed |
| Linux IME runtime observations (interactive input) | Run window/scripts/capture_moui_runtime_evidence.sh linux --require-input, or run WINDOW_MOUI_LINUX_REQUIRE_INPUT=1 bash window/scripts/check_moui_linux_smoke.sh --run on a real Wayland desktop and ensure an operator provides input while the window has focus |
Wayland desktop host + interactive input | One local run |
| Linux IME protocol functionality | WSL2 validation passed: all 8 IME probe fields (enabled/hint/surrounding/cursor/updated/updated_hint/updated_cursor/disabled) are true |
Validated with capture_moui_runtime_evidence.sh on WSL2 + WSLg |
✅ Completed (WSL2 2026-07-11) |
| Complete Linux platform-service observations | Clipboard images, directory listing, font fallback | Directory listing and clipboard images implemented and tested; first-frame rendering verified | ✅ Completed (code level) |
| Linux full evidence-manifest update | Write the complete service/IME results to the Linux entry in checks/platforms/linux.json |
Complete interactive-input IME runtime observation | One PR |
6.3 Android / iOS / HarmonyOS — Window-hosted Mainline
The embedded runtime route is wzzc-dev/window HostCmd → EventLoop →
ApplicationHandler → MoUI *EmbeddedRuntimeBackend. Host-sim coverage verifies the
template callback path, backend adapters, and Counter entrypoints without an
emulator:
sh scripts/window-hosted-hostsim-smoke.sh
| Platform | Current evidence | Remaining work |
|---|---|---|
| Android | host-sim and package checks | matching-device presentation, input, lifecycle, and service evidence |
| iOS | host-sim and package checks | matching simulator/device presentation, input, lifecycle, and service evidence |
| HarmonyOS | host-sim and package checks | signed-device presentation, input, lifecycle, and service evidence |
Use scripts/window-hosted-vm-smoke.sh with one of
WINDOW_HOSTED_ANDROID_AVD=1, WINDOW_HOSTED_IOS_SIM=1, or
WINDOW_HOSTED_HARMONYOS_HVD=1 when the corresponding target is available.
The GPU seven-gate (gpuPromotionEvidence.claimed=true) remains an independent
L3 quality declaration and is not claimed in this round.
