# 卫戍协议：盟约 — Web Remake · Architecture & Contracts (DESIGN.md)

This is the **single source of truth** for every implementer. Research lives in `docs/research/` (start with `00-INDEX.md`; where a research file's body and its "Addendum (critic)" disagree, the addendum wins). When this document and research disagree, **this document wins**; when this document is silent, follow research; when both are silent, choose the simplest faithful behaviour and write it down in the module's header comment.

Language: player-facing text is **Simplified Chinese** by default, with an English switch since 0.2.0 (§25.2, docs/I18N.md: UI strings through `t('中文')`, game texts from the official Chinese data or the official EN client's). Code, comments and identifiers are English.

Versions: the first public release was **0.1.0** (2026-10-02, the state of §0–§20.15); the releases after it add the player feedback and GitHub reports — 0.1.1 §21, 0.1.2 §22, 0.1.3 §23, 0.1.4 §24 — and **0.2.0** (2026-10-07; `CHANGELOG.md`) the maintainability refactor, two languages, 补位, 自选编队 and their fidelity work — §25 — **0.2.1** (2026-10-07) the 联防 battlefield restored, full potential and the GitHub fixes after it — §26 — and **0.2.2** (2026-10-09) per-operator 潜能 / 练度, Japanese voices, the statistics page, 失衡, whole-frame attack timing and the GitHub fixes after 0.2.1 — §27. **0.2.3** (2026-10-10; `package.json`, `shared/constants.js APP_VERSION`) 克莱门莎 and new modules, community fixes, text size, per-operator voices, installation, the opening reroll and local match recovery — §28. **0.2.4** (2026-10-11) the official shared card pool and item stock, Raid revival and #475, and the community fixes after 0.2.3 — §29. **0.2.5** (2026-10-12) fixed gifts and already displayed operator offers under the shared stock, random boss pairing, the official battlefield scenes on the 3D board (optional local art: the full bundle includes them when extracted, a missing scene keeps the metal board; §15, §30.21), the official damage-number option, the 驭械术师 / hit-tile / bot ports and the community fixes after 0.2.4 — §30; its rules supersede the corresponding 0.2.4 ones. **0.2.6** (2026-10-13) the host-bandwidth layers 0 and 1 (no BGM download while the music is silent, WebSocket compression, content-hashed asset URLs with long caching, brotli, WebP guide pages), the official scene light gains, the impostor bounds, the deploy-animation replays, the optional ammo count and the community fixes after 0.2.5 — §31, the state described by this document; its rules supersede the corresponding 0.2.5 ones. The labels v1 / v2 / v2.1–v2.5.2 in §0, §14–§20 and in the BALANCE / SIM comparisons name the design generations and the private playtest builds that came before it; they are kept as history.

## Where each section lives

Section numbers are global and never change: code, tests and the other documents cite them as "DESIGN §N". The
current rules by area are in `docs/design/`, the per-release revisions (the evidence behind each rule) in
`docs/history/`. When a revision changes a rule, the rule in `docs/design/` is rewritten too (the revision lists the
normative lines it rewrote).
