+> 2026-08-25 RED/GREEN: new contracts require a fixed 184-DIP expanded sidebar, 38-DIP collapse/auto-collapse, no resize surface/provider/handlers, and a centered `PageJumpGroup` toolbar overlay with a reserved action-row footprint. The focused slice failed against the pre-change implementation; the live STA layout now also proves the page-jump center matches the floating toolbar center within one DIP.

 ## Purpose
 
 Wave4 source and WPF contract tests for the compact page jump and custom document navigation rail.

+> 2026-08-25 RED/GREEN: toolbar polish rejects the obsolete resize style/metadata and requires a fixed sidebar plus centered page-jump overlay markers while retaining localized tooltips and existing icon contracts. The focused 23-test class passes.
+
 ## Purpose
 
 Source-level contracts for the Wave 3 editor toolbar affordance repair. These tests protect the visible toolbar boundary without requiring a WPF desktop session: obsolete Fit/preset/Ink Analysis entry points must be absent, laser and highlighter visuals must be vector-backed, shape/highlighter popup choices must expose real previews, and toolbar metadata must remain localizable and stable.

 ## Current Work
+- 2026-08-25: OpenNotes 5.2.2 navigation-layout patch is GREEN. The expanded document sidebar is fixed at 184 DIPs with no resize surface/provider and retains 38-DIP explicit/narrow collapse; the unchanged one-based page navigator is a centered toolbar overlay with a reserved action-row footprint. Runtime STA geometry is centered within one DIP. Release tests pass 286/286, build has 0 errors, i18n passes 293/480/0, and all version surfaces match 5.2.2/5.2.2.0. The user's 50.04-MiB, 1,353-page PDF opened in the 5.2.2 Release executable, committed page 2, and stayed alive about three minutes; the generic smoke stopped only on its generated-fixture outline-ID assumption and cleaned isolated data. Next: commit/push/tag, published installer upgrade, and launch.
 - 2026-08-25: OpenNotes 5.2.1 large-PDF crash hotfix is ready for release. Windows event 1026 tied the user's 5.2.0 crash to `DocumentOperationSession.Capture` reading a CTS disposed by `Cancel` during the load/autosave transition. RED reproduced the exact `ObjectDisposedException`; GREEN keeps the inactive CTS cancelled until `Begin`/`Dispose` retires it. Release tests pass 286/286, Release build has 0 errors, i18n passes 294 entries/482 calls/0 hard-coded strings, and the user's 50.04 MiB/1,353-page textbook opened and survived a 90-second hold across the 60-second autosave tick without a .NET crash. The large document's private memory settled near 1.42 GiB; this hotfix fixes the evidenced termination without changing PDF/render/save architecture. Next: commit/push main, tag/push `v5.2.1`, and verify both GitHub Release assets.
 - 2026-08-24: OpenNotes 5.2.0 source is ready for release at the user's request. The complete current toolbar/sidebar/shape and page-template worktree is aligned across project/ProductInfo/AppX/installer/test metadata while preserving legacy Caelum/WindowsNotesApp identities. Fresh Release build passes with 0 errors, Release tests pass 277/277, i18n passes 294 entries/484 calls/0 hard-coded strings, version surfaces match 5.2.0/5.2.0.0, and diff check exits 0 with known line-ending notices. Next: commit and push `main`, push annotated `v5.2.0`, then verify the tag-driven GitHub Release and both assets.
 - 2026-08-24: Screenshot-driven editor toolbar/shape polish is complete. The sidebar right edge and transparent 32-DIP resize target render no vertical line; top-bar actions use one 18-DIP owner-foreground Lucide treatment with separate pen/highlighter color bars; a rounded themed WPF ToolTip template displays the existing localized EN/ZH/FR names; and the shape popup is a checkmark-free 3×3 catalog with Triangle, Diamond, Parallelogram, Pentagon and Hexagon added to the ordinary ink/undo/save pipeline. RED/GREEN focused coverage passes 29/29, combined editor coverage 58/58, the full suite 277/277, Debug build 0 errors (2 existing NU1701 warnings), i18n 294 entries/484 calls/0 hard-coded strings, diff check exits 0, and offscreen WPF previews confirm the final chrome/popup layout.

+## Fixed sidebar / centered page navigation (2026-08-25) — GREEN
+
+- Remove the sidebar resize thumb, range automation peer, resize handlers and resize-only width state. Expanded width is fixed at 184 DIPs; explicit and narrow-window collapse remains 38 DIPs and expands back to 184.
+- Keep the toolbar action row horizontally scrollable, reserve a transparent 150-DIP slot after the ruler action, and host the unchanged `PageJumpGroup` in a centered overlay sibling so action order no longer shifts the page number.
+- Preserve page-jump one-based editing, previous/next commands, page count, localization, and existing AutomationIds.
+- STA layout evidence proves the page navigator center matches the floating toolbar center within one DIP. The user's 50.04-MiB, 1,353-page PDF opened in the 5.2.2 Release executable, accepted a page-2 jump, and remained alive for about three minutes; the generic smoke then stopped only because the textbook's real outline does not expose its synthetic fallback `Outline.Page.2` fixture ID.
