 # Work Log

+## 2026-06-06
+
+- Fixed the desktop Dock so route changes from Dock menu links no longer leave focus-held open state behind when the Dock is not pinned.
+- Kept the saved `dock-pinned-v2` preference unchanged during navigation and only released transient Dock focus/hover state after menu clicks and pathname changes.
+- Validation: `npm run lint` passed and `npm run build` passed. In-app browser verification on `http://localhost:3111/` confirmed that after unpinning the Dock, clicking the Dock archive menu navigates to `/archive`, the pin button remains `aria-pressed=false`, and the Dock collapses after the pointer leaves.
+- Recommended next task: do one visual pass on the Dock at narrow desktop widths to confirm the collapse animation still feels smooth around the sidebar offset.
+
+## 2026-06-02
+
+- Refined the public layout after desktop/mobile review: the shell now guards horizontal overflow, uses route-aware bottom padding, hides the top menubar on mobile, and opens the mobile sidebar/search panel from the Dock.
+- Reworked the Dock so mobile uses it as the primary navigation hub, while desktop keeps a folded Dock that expands on hover/focus and includes a pin toggle.
+- Smoothed the desktop Dock hide/show interaction by separating hover-open, closing, and fully-collapsed states; the Dock now keeps the expanded hit area during the closing animation so re-entering mid-collapse reverses smoothly.
+- Changed the desktop Dock's default state to pinned/open and added distinct soft pastel tones to Dock buttons, including stronger visual treatment for pin/unpin and auth actions.
+- Softened the Dock button palette to quieter pastel tones and made the light-mode Dock bar read as a cleaner white glass surface.
+- Fixed the Dock pin toggle so mouse-based unpinning no longer leaves button focus holding the Dock open, and changed the Dock Home button to a white neutral tone.
+- Reworked the Dock material away from cute pastel tiles into a more macOS-like neutral frosted glass texture with translucent white glass buttons.
+- Corrected the Dock button direction so only Home stays white, while the other actions keep subtle pastel tints with a translucent macOS-style glass material.
+- Increased Dock button translucency contrast so the buttons remain glassy while sitting slightly more opaque than the Dock background.
+- Rebalanced the home page around latest posts with popular posts as a supporting panel, converted the post detail page into a quieter reader surface, and hardened Markdown/code/table wrapping against mobile overflow.
+- Added a client-side archive explorer with year, month, category, and compact/comfort density controls over the existing server-fetched post list.
+- Rebuilt the chess page with safer viewport-aware board sizing, quieter puzzle panels, and enough layout clearance for the Dock.
+- Validation: `npm run lint` passed and `npm run build` passed. In-app browser verification on a local `next start` server confirmed no horizontal overflow on `/`, `/archive`, and `/play/chess` at mobile width, mobile Dock-centered navigation opens the sidebar panel without overflow, desktop CSS loads, the mobile Dock is hidden on desktop, and the desktop Dock starts folded with a pin control. The live chess board itself could not be verified because the local backend chess API was unavailable, so `/play/chess` rendered the error state.
+- Validation: `npm run lint` passed and `npm run build` passed. In-app browser verification on a local `next start` server confirmed the desktop Dock starts as a small bottom tab, uses 560ms transitions for tab/panel geometry, and expands into the larger Dock hit area when opened.
+- Validation: `npm run lint` passed and `npm run build` passed. In-app browser verification on a local `next start` server confirmed the Dock opens by default and Home/Archive/Chess/Login/Signup/Pin buttons render distinct pastel colors.
+- Validation: `npm run lint` passed and `npm run build` passed. In-app browser verification on `http://localhost:3106/` confirmed the light-mode Dock bar renders as a cleaner white glass surface and the Dock button colors use quieter pastel tones.
+- Validation: `npm run lint` passed and `npm run build` passed. In-app browser verification on `http://localhost:3107/` confirmed the Dock Home button renders white and mouse-based unpinning collapses the Dock after the pointer leaves.
+- Validation: `npm run lint` passed and `npm run build` passed. In-app browser verification on `http://localhost:3108/` confirmed the Dock uses neutral translucent glass material, with non-home buttons rendering as subtle white glass rather than pastel color tiles.
+- Validation: `npm run lint` passed and `npm run build` passed. In-app browser verification on `http://localhost:3109/` confirmed Home stays white while the other Dock buttons keep pastel-tinted translucent glass backgrounds with button-level blur.
+- Validation: `npm run lint` passed and `npm run build` passed. In-app browser verification on `http://localhost:3110/` confirmed Dock buttons remain translucent but render slightly more opaque than the Dock background for clearer contrast.
+- Recommended next task: run a browser pass against a reachable backend API, especially one real post detail route and the populated chess puzzle board, then tune any remaining content-specific long-title or board-height edge cases.
+
 ## 2026-05-29

+- Fixed post detail 404s caused by double-encoding dynamic route slugs that already arrive percent-encoded from URLs such as `/posts/soft-delete%2C-hard-delete`.
+- Updated the public post fetch helper to decode a route slug once before encoding it for the backend API path, preserving normal Korean/special-character slug requests while avoiding `%252C`-style API lookups.
+- Validation: `npm run lint` passed and `npm run build` passed. A local production server with `NEXT_PUBLIC_API_URL=https://blogserver.wypark.me` returned real post titles for `/posts/soft-delete%2C-hard-delete`, `/posts/destructuring-%26-component%ED%95%A8%EC%88%98`, and `/posts/rtr-(refresh-token-rotation)`.
+- Recommended next task: deploy the slug normalization fix before re-checking affected live post URLs in Search Console or the browser.
 - Added a category post-list page size control with 9/18/27 options, defaulting to 9 and persisting the user's choice in `localStorage` under `categoryPageSize`.
 - Wired the selected category page size into the React Query key and `getPostsByCategory` request size, resetting to page 1 when the size changes while preserving search behavior.
 - Adjusted the category page toolbar so search, page-size controls, and grid/list controls stack cleanly on narrow screens and align in one row on desktop.
