 # Work Log
 
+## 2026-06-24
+
+- Refined the chess board visual style to match the app's glass/control surfaces instead of the previous heavy wood-and-token treatment.
+- Removed the circular chip backgrounds from pieces, kept high-contrast glyphs with subtle outlines, softened square/highlight colors, and tightened coordinate labels for a cleaner chess UI.
+- Rebalanced chess board sizing and layout columns so the board window, actual board, side panel, and Dock spacing feel less awkward on a 1280x720 desktop viewport.
+- Validation: `npm run lint` passed and `npm run build` passed. Browser verification on `http://localhost:3124/play/chess` with a temporary local puzzle API confirmed 64 squares, 32 rendered pieces, a 350px visible board above the Dock, balanced 480px/320px board-panel windows, and no console errors. The temporary API was stopped after verification.
+- Recommended next task: verify the real authenticated `/chess/play/{gameId}` board against the Maia backend at common laptop heights and tune only the board size formula if the live game info panel changes vertical rhythm.
+
+## 2026-06-19
+
+- Added Maia game resign and undo API wrappers, then wired the play screen with in-progress-only "무르기" and "기권" actions plus a persistent "새 게임" link back to the setup screen.
+- Locked board/actions during move, undo, and resign requests, updated the game cache from backend responses as the single source of truth, and refreshed history/stat queries after successful state changes.
+- Added resigned-loss labeling so play, recent games, and history can show `기권패` for `RESIGNED` losses while still grouping them under losses.
+- Validation: `npm run lint` passed and `npm run build` passed. Authenticated browser verification against the live Maia backend was not run in this session.
+- Recommended next task: test resign and undo with an authenticated real game, including black-player games where Maia's opening white move must remain after undo.
+
+- Reworked the shared chess board UI with a bordered board surface, high-contrast chip-style pieces, stronger selected/legal/last-move highlights, and transform-based piece movement transitions so player and Maia moves read as motion instead of instant jumps.
+- Connected the daily puzzle board to the shared `ChessBoard` component, removing duplicated piece rendering and adding drag/drop support for puzzle moves.
+- Updated Maia play state so optimistic player moves are highlighted locally while pending, then Maia's returned move can animate from the server response; changed the pending overlay into a small status pill so it no longer hides the board.
+- Validation: `npm run lint` passed and `npm run build` passed. A local dev server is running on `http://localhost:3124`; browser verification with a temporary local puzzle API confirmed 64 squares, 32 piece-layer nodes, 0.42s piece transition styling, square selection/legal target markers, and no console errors. The temporary API was stopped after verification.
+- Recommended next task: verify `/chess/play/{gameId}` against the real Maia backend with an authenticated account to tune the exact Maia response timing and capture/promotion edge cases.
+
+- Added the authenticated Maia chess frontend: `/chess` lobby with rating/color/model and advanced settings, `/chess/play/[gameId]` playable board with backend FEN synchronization and PGN copy, and `/chess/history` account game history with outcome filters.
+- Extended the chess API client and shared types for Maia game create/list/stats/detail/PGN/move endpoints while leaving the public `/api/chess-puzzles/**` puzzle request unchanged.
+- Updated the Dock/menu/shell route handling so Chess opens the Maia lobby, with the existing public puzzle page still available at `/play/chess`.
+- Validation: `npm run lint` passed and `npm run build` passed. A foreground `next dev --port 3122` startup reached Ready, but persistent detached/browser verification could not be completed because sandbox-launched background dev processes exited or hung before serving requests.
+- Recommended next task: verify `/chess`, `/chess/play/{gameId}`, and `/chess/history` in an authenticated browser session against a reachable backend, especially real Maia move latency/error responses.
+
+## 2026-06-07
+
+- Fixed admin pages being pushed outside the visible content area by removing viewport-based `md:w-[80vw]` widths from the admin route shell and Markdown editor container.
+- Changed admin containers to use the remaining shell content width (`w-full` with `max-w-[1400px]`) so the sidebar margin no longer combines with an extra viewport-width layout.
+- Validation: `npm run lint` passed and `npm run build` passed. Authenticated browser verification was not possible in the current session because `/admin` redirects to login without an admin token.
+- Recommended next task: verify `/admin` and `/admin/posts/new` in an authenticated browser session at desktop widths around 1280px and 1440px.
+
+- Fixed the admin dashboard traffic chart visibility by giving bar columns a real height context, so percentage-based bar heights render instead of collapsing.
+- Added fallback traffic points from recent/popular post data when the dashboard API or `traffic` array is empty, keeping the graph visible while the backend traffic aggregation is unavailable.
+- Validation: `npm run lint` passed and `npm run build` passed. Browser navigation to `/admin` was attempted on `http://localhost:3112/`, but the current browser session was unauthenticated and rendered the login screen, so the admin chart itself was validated by code path and build checks rather than a live authenticated screenshot.
+- Recommended next task: verify `/admin` with an authenticated admin session against the production API to confirm the real `traffic` payload replaces the fallback graph.
+
+- Simplified the macOS-inspired layout by removing duplicated navigation surfaces: the desktop shortcut icon layer, the home page's inner Finder sidebar, and app navigation links from the system menu bar.
+- Reworked the global sidebar into a cleaner library panel focused on profile, search, and categories, with a quieter compact profile row and no duplicated app shortcuts.
+- Kept app-level movement in the Dock, category/search movement in the sidebar, and current-context/status information in the menu bar so each shell area has a clearer role.
+- Validation: `npm run lint` passed and `npm run build` passed. In-app browser verification on `http://localhost:3112/` confirmed no horizontal overflow, no desktop shortcut duplicates, the simplified home window, the Korean sidebar header, and no browser console warnings/errors. The local backend remained unavailable, so the home page showed empty post states.
+- Recommended next task: test the simplified sidebar with real production categories and long category names, then tune category row spacing if the populated tree feels too dense.
+
+## 2026-06-06
+
+- Reworked the macOS-inspired shell into a fuller desktop illusion: full-width system menu bar, floating Finder-style sidebar window, viewport-centered Dock, desktop wallpaper layers, and desktop shortcut icons for major destinations.
+- Rebuilt the public home screen as a Finder window with a locations sidebar, disk/status strip, file-like post rows, Spotlight-style search results, and stronger shared window glass treatment.
+- Extended the OS treatment across archive, category, reader, login/signup, admin shell, post cards, and list rows, including file icons, Reader window framing, and cleanup of a stale mojibake notice-category check.
+- Validation: `npm run lint` passed and `npm run build` passed. In-app browser verification on `http://localhost:3112/`, `/archive`, and `/login` confirmed no horizontal overflow, desktop/mobile menu and Dock visibility rules, shared window surfaces, and no browser console warnings/errors. The default local API data rendered empty post states during the browser pass.
+- Recommended next task: run a visual pass against `NEXT_PUBLIC_API_URL=https://blogserver.wypark.me` so populated post lists and one real reader page can be tuned with long Korean titles and real content.
+
+- 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.

 - 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.

 - 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.
