feedback7 G-SMALL: settings can copy local diagnostics for a bug report (PR #321 by @Cloudnyco)

Applied 设置 → 问题反馈. The report stays in the browser: the in-memory error log, device info, and the battle on screen only while 「附上本场战斗」 is on. Nothing is uploaded.

Redaction no longer treats a long name as a bare substring. Prose replaces each secret only as a whole token, so a name does not cut a longer word or a chess id. The attached JSON replaces a string only when it equals the secret, so chess_char_1013_chen2 and a note like "charge the char" stay, while an exact "char" value becomes the placeholder. The token boundary is a consumed prefix plus a lookahead, because a lookbehind is a SyntaxError in Safari before 16.4. PLAYING section 12 stays; the other section-12 proposal is not in this batch.

Tests: node --test test/diag.test.js — 10 pass. node --test test/client-static.test.js — 315 pass. node --test test/match/runner-pending.test.js test/match/watch-bonds.test.js test/ui/playtest6-unite.test.js test/ui/spectate-effects.test.js test/ui/feedback5-hotkeys.test.js test/i18n-server.test.js test/ui/bosshit-ticker.test.js test/ui/playtest3.test.js test/docs-consistency.test.js test/docs-paths.test.js test/version.test.js test/package.test.js — 138 pass. npm run -s lint — 0 errors. npm run -s typecheck and npm run -s check:imports passed. node tools/i18n.mjs check --all --strict — 1041/1041 in en, ja, ko and zh-TW, 0 errors.
