rockyandClaude Opus 5 5d51c5bf77 chore: snapshot uncommitted local work before rebasing onto cloud-agent

Safety commit so the 94 uncommitted files in the working tree (in-flight
Account/Mac/Tip work plus the feature-preview recording tooling) survive the
move onto cursor/cloud-agent-1787824905651-vxuwc.

Raw Blame History

Typing Keyboard Baseline (Phase 0)

文档状态：Phase 0 冻结基线（历史快照，2026-08-03）。它记录当时的选型依据，不随版本更新。当前权威的依赖版本与许可以 NOTICE-TYPING.md 和 OSGKeyboard/Resources/Typing/Rime/manifest.json 为准；实施进展见 docs/keyboard-accuracy-plan.md。

Frozen reference for NanoMouse × OSGKeyboard fusion.

NanoMouse reference

Field	Value
Repo	https://github.com/xjwhnxjwhn/nanomouse
Frozen commit	`a6177d898a01662ce551b43a01cf82a9f84ca54c` (2026-07-29 tip at clone)
Local clone (gitignored)	`.refs/nanomouse/`

KeyboardKit / key shell

NanoMouse does not SPM-pin upstream KeyboardKit Pro. It vendors an MIT KeyboardKit tree inside:

ios/Packages/HamsterKeyboardKit/Sources/KeyboardKit/ (see that folder’s LICENSE).

OSG ships a lean SwiftUI key shell in-repo (OSGKeyboardExt/Typing/) behind TypingLayoutProviding; KeyboardKit is not linked.

KeyboardKit Pro is not used.

Chinese schema / lexicon

Choice	Detail
Product intent	Full pinyin + Microsoft/Sogou double pinyin + opt-in fuzzy pairs
Engine	librime 1.17.0 via static XCFramework (BSD-3-Clause)
Binary package	`ghostflyby/librime-xcframework` `1.17.0-pack.1`, checksum `0f0fc13b…1164`
Baseline	rime-pinyin-simp (Apache-2.0)
Modern words	Jieba frequencies + phrase-pinyin-data + pinyin-data (MIT)
Generated lexicon	`Resources/Typing/Rime/osg_pinyin.dict.yaml` (~365K entries)
User learning	librime userdb in App Group
Explicitly excluded	rime-ice / rime-double-pinyin (GPL), Luna / Essay (LGPL)

The dictionary is rebuilt deterministically by Scripts/typing/build_rime_dictionary.py; manifest.json pins every source commit and SHA-256.

Memory / height budget

Mode	Target height	Memory notes
Voice	281 pt (`KeyboardRootView.totalHeight`)	Matches typing height; no typing engine loaded
Typing	281 pt (`TypingRootView.totalHeight`)	Host-prebuilt Rime data; extension opens one session
RSS goal	Typing peak < 50 MB	Session closes on voice switch / memory warning

Success criteria (Phase 1)

Top-right tab switches voice ↔ typing; recording/processing locks voice.
English QWERTY + 123 / basic symbols.
Full pinyin and Microsoft/Sogou double pinyin produce phrase candidates.
Fuzzy pairs default off and are enabled individually in Settings.
No GPL/LGPL input data in the app; NOTICE lists exact source licenses.
