 ## Progress log
 - **2026-10-13 (G14, Vietnamese localization):** Added Vietnamese (`vi`, Tiếng Việt) as an interface and date language with a 2,591-entry catalog (`plural_none`) covering 100% of the current localizable key union (plus `theme`/`Appearance`). Locale tags `vi` / `vi-VN` / `vi_VN.UTF-8` resolve; calendar months use numeric `Tháng 1`…`12` / `tháng 1`…`12`. Native-speaker community review recorded. The twelve-language localization mean moves from ≈59% to ≈68%; weighted readiness ≈49% → ≈50%. Status stays `partial`: engine/OS details, document contents, filenames, CLI/MCP and external help stay outside the catalog by design.
 
+- **2026-10-14 (M3 #2080 candidate):** Existing per-tab page history gains explicit search jumps, rail buttons and control-channel commands. Continuous scrolling and automatic search refresh stay outside history; page-level restoration and estimates unchanged.
+
 - **2026-10-13 (M2, page-unit transform precision):** Preserve small transform coefficients in page marks, added content and print output. Regression cases cover accepted page units of 4096 and 75000; existing page-unit interpretation and estimates are unchanged.
 - **2026-10-14 (M5, PR #1457 branch refresh):** Merged upstream main and reconciled roadmap entries while preserving comment submission shortcuts. Estimates unchanged.

+## Viewer navigation history
+
+A running PdfCraft instance launched with `--control FILE` exposes its per-tab history through
+`pdfcraft-cli ui --control FILE command id=view.previous_view` and
+`pdfcraft-cli ui --control FILE command id=view.next_view`. `commands` reports whether each action
+is enabled for the active document. These are the same actions as the rail buttons, View → Page
+navigation, and Ctrl+[ / Ctrl+] (⌘[ / ⌘] on macOS).
+
+Explicit page jumps, including search-result selection and Next/Previous match, enter history
+when the page changes. Automatic search refresh, continuous scrolling, and within-page scroll
+movement do not. Existing page-step commands and single-page wheel turns retain their history
+behavior. Back/Forward
+returns to page tops, does not restore zoom, does not switch documents, and is not saved across
+restarts. Standalone engine/MCP sessions have no viewport, so they do not have a separate
+navigation-history tool; use the opt-in UI control channel to navigate the displayed document.

Native-opening candidate: chosen tools survive preparation and password retries; startup intake waits for pending preparation. #1980: exact quit modifiers preserve Ctrl+Alt+Q email input; Ctrl+Q/Cmd+Q asks before discarding unsaved documents. |

 | M2 | Model, render, text | 200–350 | 15% | 130–230 | hayro bootstrap renderer (vendored patches); inspector predictor scratch is bounded by available input, and JPX sample rescaling handles 1–32 bits safely. Text extraction reaches word-F1 0.98 against pdftotext. Short same-line redraws split before placement rather than interleaving. A custom text match that ends on a reconstructed separator stops before the next glyph (#1315). Missing: model crate, fonts, DisplayList, renderer independent of hayro. Inspector page-label traversal and output are resource-bounded, with physical-number fallback warnings |
