+- Restored cross-month history visibility for Daily Report, monthly processing and company-channel generation history.
+  Each list now has an independent previous/month/next/`本月` navigator and defaults to its latest non-empty month using
+  authenticated read-only `GET /api/history-months`. Counts and empty states name the active month and can jump to the
+  latest month with records. Company `生成月份` is now visibly labeled and independent from history `查看月份`; monthly
+  polling follows the viewing month without changing generation contracts. A guarded live read returns July counts of
+  30 daily and four monthly records, while company state retains four July jobs. The full 356-test suite passes with 10
+  skips, and isolated Chinese/English/Thai browser QA at 1440/900/390 pixels found no page overflow. Port 8766 was
+  restarted under detached Screen and is `ready`; no upload, report generation, source activation or business-data write
+  occurred.

+- Refined the Channel BI utility surface in preserve mode: removed the visible BI panel heading and ready-state
+  `数据库已连接` copy while retaining the navigation label, browser metadata and semantic status dot. Compressed the
+  month selector to a compact control on desktop/H5, and changed task-log/logout utilities from button chrome to
+  low-emphasis accessible links without changing their behavior. JavaScript syntax plus focused BI, daily visual,
+  task-log and auth tests pass; no API or business data changed.
+- Tightened the Channel BI panel's top rhythm after the heading removal: the desktop panel now starts 20px higher
+  relative to the shared 38px page padding, while the responsive desktop shell keeps a 10px mobile-only adjustment.
+  The four-tab bar, panel content and BI data behavior are unchanged; focused Web regression remains green.
+- Refined the Channel BI presentation and data-range contract. Removed the BI-only CHANNEL PERFORMANCE, snapshot
+  watermark copy and visible TOTAL PRICE labels on desktop and H5, and added a localized 数据范围 line below the
+  company-sales title. The read-only analytics payload now supplies the minimum and maximum ARRIVAL coverage dates
+  from one repeatable-read current-version snapshot; no Finance/report business data changed. JavaScript syntax and
+  focused analytics/Web/UI tests pass.
+- Implemented the ARR Web Chinese/English/Thai presentation layer. Desktop, H5 and login now share `arr_web/static/i18n.js` with locale selectors, localStorage/cookie preference, `html.lang`, dynamic prompt/API-error translation, Bangkok/Gregorian/Latin-digit date/number formatting and locale-aware duration/money display. The runtime preserves original source strings so switching back to Chinese is safe. `ARR Report`, operational proper nouns, business/API behavior and XLSX/monthly/company report output contracts remain unchanged. Scoped Web regression passed 61/61; full discovery still has only the pre-existing environment errors for missing `httpx`/unavailable OSS client.

 ## Verification Status
 
+- The 2026-07-31 Web i18n implementation passed JavaScript syntax checks, a DOM/runtime locale smoke (Chinese → English → Thai → Chinese), and 61 focused ARR Web tests. A full 298-test discovery was attempted; eight import/runtime errors are environment-only (`httpx` absent and OSS client unavailable), with no i18n-related failure.
 - Migration 012 passed transaction-only up/down probes, including a synthetic active publication followed by rollback.
 - The 38-test monthly/migration/Web regression set passed, including real XLSX build/reopen checks.
 - A clean full-suite rerun with the optional ARR1 compatibility dependency installed passed 291 tests in 108.2 seconds
