feat(ohos): window-ignore-cursor-events + adapter tests + print/https-scheme fixes

[ljy9812]

Summary

window-ignore-cursor-events (verified, archived)

• Full openspec change (proposal/design/specs/tasks + plan)
• set_ignore_cursor_events → set_window_touchable(!ignore) via TSFN
• TestRunner button + ohos-adapter test wiring (was never imported)
• manual_tests.md ch.28 + chapter numbering fix
• ohos-constraints.md §1.5 (ExternalError conversion constraint)

ACL fix

• create_ohos_test_webview was rejected by ACL — added to app_manifest + run-app.json

Print fix (ohos-webview-print)

• print.js injection for OHOS (was macOS/iOS only)
• ohos.permission.PRINT in module.json5 templates
• manualOhosPrint calls window.print() (shim) not getCurrentWebview().print()

HTTPS scheme fix (ohos-webview-https-scheme)

• tauri-runtime-wry OHOS branch forwards with_https_scheme (was missing)
• Init script auto-checks isSecureContext + crypto.subtle

drag_drop_overlay API (3-layer, cfg-gated)

• tauri-runtime + tauri + tauri-runtime-wry: drag_drop_overlay field + builder + OHOS passthrough
• #[cfg(target_env = "ohos")] gates the API surface so non-OHOS platforms have no such field (6 sites)
• cmd.rs create_ohos_test_webview call site wrapped in cfg + let _ = suppressor on other platforms

webview file drag-drop — COMPLETE (device-verified 2026-08-07) [NEW COMMIT]

• onLoadIntercept file:// interception (DefaultWebview.ets, WebBuilder + EmbeddedWebBuilder): ArkWeb consumes OS file drops by navigating to file://<dropped file> → ERR_ACCESS_DENIED → white screen (a kernel behavior desktop Tauri webviews do not have). The Web-level .onDrop fires unreliably (ArkWeb preempts it) and setResult(DRAG_SUCCESSFUL) is ineffective on the Web component. Resolution: a file:// branch in onLoadIntercept returns true to cancel the navigation (no white screen) and forwards the path via the drag-drop pipe drop|<path>|0,0. Whole webview becomes a drop zone, touch not blocked. Safe: Tauri OHOS loads via custom protocol (tauri:// / https://<proto>.localhost) or inline html, never file://.
• openspec wire format: corrected paths_csv (comma) → paths_nul (\0-separated) so paths containing commas survive; both specs + plans updated with the device-verified result.
• openspec change archived to openspec/changes/archive/2026-08-07-ohos-webview-drag-drop/.
• Companion PR: Eulogizethesun/openharmony-ability chore(deps): replace cross-repo path deps with git deps #43 (drag.rs entity, DefaultWebview.ets onLoadIntercept + buildDragPipe).

openspec

• 4 specs flagged with verification-status notes
• ohos-dialog-error + ohos-window-ignore-cursor-events + ohos-webview-drag-drop archived

Real-device verification (API 23 desktop)

Feature	Result
monitor	✅ PASS (3120×2080)
clipboard flag	✅ PASS
zoom flag	✅ PASS
ignore-cursor-events	✅ PASS
dialog error	✅ PASS
print	✅ PASS
https-scheme	✅ PASS (isSecureContext=true)
RunEvent::Resumed	❌ known (not firing)
drag-drop (onLoadIntercept)	✅ PASS (no white screen, path received, frontend displays it)

Test plan

• cargo check (ohos target) + Windows host cargo check (no cross-platform pollution)
• Full build + deploy + autotest (250 tests)
• Real-device manual verification (9/10 PASS — drag-drop now passing)
• No cross-platform pollution (cfg target_env=ohos)
• Rebased on upstream/ohdev latest (bd3b803)

Code Review (babysit)

✅ Clean — 0 Blocker, 0 Major

• cfg isolation: correct (target_env=ohos, no cross-platform pollution)
• NAPI/TSFN: N/A (this repo has no TSFN code)
• print.js injection: macOS/iOS cfg extended with OHOS (correct)
• tungstenite unconditional dep: Minor (build.rs cfg limitation, documented)

2 Minor noted (non-blocking): tungstenite dep, drag_drop_overlay field on cross-platform struct (default false, harmless).

OHOS Code Review — tauri#71 (ohos-webview-drag-drop)

自审巡检（pr-babysit）。共 4 findings，0 🔴 Blocker，故为 COMMENT。

🔴	🟡	🔵	ℹ️
0	1	2	1

• 🟡 F1 openspec/specs/ohos-webview-drag-drop/spec.md:49 wire format 矛盾（见 inline）— 真实 bug，建议修
• 🔵 F2 changes/ 下 dialog-error 相关 change 未归档（proposal/tasks 缺失）
• 🔵 F3 统计表标题与覆盖内容不一致
• ℹ️ F4 proposal 归档标注不完整（部分 task 状态未同步）

F1 经对抗性验证确认（line 49 说用 , 连接 paths_nul，与 line 26 定义 + line 32 示例的 \0 矛盾；含逗号路径会被 wry 侧 split('\0') 破坏——恰是 line 26 设计要避免的故障）。其余为文档卫生问题。

检视意见回复

已确认所有 4 个 findings 均已修复（commit a0bb8a6）：

• F1: wire format 矛盾 - spec.md:49 已修正为 \0，与 line 26 定义 + line 32 示例一致
• F2: dialog-error 未归档 - ohos-dialog-error change 已归档至 openspec/changes/archive/2026-08-06-/
• F3: 统计表标题不一致 - manual_tests.md 统计表已给予独立 section 标题
• F4: proposal 归档标注不完整 - proposal.md 已添加状态+遗留项；tasks.md task 11 已标记 Deferred

无遗留问题，可以合并。
