按笔顺拆前两个部件、各取读音首字母（妈 = 女 n + 马 m = nm），部件用加加俗称读音（亻=d、 扌=t、纟=j、忄=s、攵=f、夂=z、刂=l、彳=s）；138 个独体/部首字取「本字声母 + 起笔」。码表 7968 条，覆盖《通用规范汉字表》7846 字，比小鹤少 422 个扩展区生僻字——缺码会让含这些字的 词组拿不到辅助码，是已知取舍。 编码对齐拼音加加 5.x 安装包内的 fzm.bin（双拼键位已换算为声母）：6487 字取到两码，6349 字 逐字一致，138 字保留本表规则，覆盖外的 800 字按同一规则重建。来源与非官方性质写在 NOTICE.md 与随包的 THIRD_PARTY_NOTICES.txt。 - engine/contracts/assets 注册 helpcode_jiajia，assets.h 重新生成（5 → 6） - 设置页两个下拉显示名「加加」，两份配置模板注释同步 - 两侧测试补支持列表；README / README.en.md / server/AGENTS.md 改「六套」 默认值不变（双拼 lantian、全拼 ziranma）。
Product contracts
These headers are independently consumable C++17 contracts. Including them does not link the input engine, start threads, access dictionaries, or require any third-party code. The TSF text service consumes only these headers; the server consumes the same source by linking the engine. Both live in this repository — windows/ and server/ — and so does the engine, so one commit covers all three and there is no pin to keep in step.
windows_ipc.h owns the wire layouts, pipe names and opcodes. voice_composition_pipe.h owns voice framing. Consumers may wrap these headers but must not duplicate their definitions.
punctuation/policy.json is the source of truth for the ASCII punctuation keys and their Chinese
translations. Its generated policy.h is consumed by the engine and included directly by the hosts
that route punctuation keys. Stateful quote alternation and nested book-title marks remain
part of the same contract, rather than being re-created in each host.
product_lock.py contains the shared product-lock primitives used by the three platform locks.
See product_lock.md for the vendoring and byte-equality rule.
Main handshake
Reverse endpoints retain their 16-byte hello and PipeReady acknowledgement. Once both endpoints are registered, the new client sends the existing 304-byte ClientHello with:
| Field | Meaning |
|---|---|
| keycode | MSIP magic |
| wch | Major wire protocol version |
| point[0] | Minor additive version |
| modifiers_down | Supported capability bits |
| point[1] | Required capability bits |
| request_id | Nonzero registration correlation ID |
The Server sends ProtocolReady or ProtocolMismatch on the registered reply endpoint before activating the main route. The reply echoes the correlation ID and contains major/minor, negotiated capabilities and magic in the first six UTF-16 units. These packets are consumed only during registration and are never text commits.
Existing DLLs with unversioned hello remain accepted by the new Server using the established v1 semantics; they receive no new opcode. New DLLs require an acknowledgement from the new Server within the existing bounded handshake budget. Against an old or incompatible Server they remain disconnected and use the existing raw-input fallback, rather than interpreting unnegotiated frames. A late acknowledgement from an old registration cannot authorize another one.
Append opcodes; never change released values or reuse them. An incompatible layout needs a new major protocol and an explicit migration, not another copy of a header. Minor additions must be optional capabilities.
CharacterSetShortcut is optional and is not included in the default capability set.
Windows implementations that support it pass Capabilities | CharacterSetShortcut
to Hello / Negotiate. Only after negotiating this bit may a Chinese-mode client
consume Ctrl+Shift+F (no Alt or Windows modifier) and send the existing KeyEvent
with keycode F and Shift/Control modifier bits. The server toggles the persisted
character set without clearing composition, and refreshes the current candidate
page and toolbar. It sends no key reply. Clients suppress auto-repeat and must not
replay an ambiguously delivered toggle; older peers simply omit the optional bit.
tests/windows_ipc_contract.cpp executes wire-layout/upgrade/framing cases on all Engine CI platforms and both Windows TSF architectures.
