 ## Product Contract
 
-Tasteful Intent is a greenfield Tauri desktop Markdown editor for human-authored intentions. The selected `libraryRoot` remains canonical Intent source data. AI keeps one ordered list of user-selected canonical folder tabs with one root-local session per tab; pinning is a tab property represented by an optional 1-2 grapheme label, not a separate source mode. AI edits content through the shared Edit, View, and Split modes and the existing atomic-save/mtime-conflict boundary; AI can create a new Markdown document in the selected folder from the document-list header, and the new document opens in Edit; AI folder creation, rename, move, and Trash remain unavailable. AI View adds a read-only git-diff view cycle (changes-only with collapsed context → full document with highlighted changes → off) that compares the active document body against its git HEAD baseline; it never runs mutating git commands and hides itself when git or a repository is unavailable. Do not add migration adapters for the former PromptPad product. LLM runtime, tags, toolbar, and wiki features are outside v0.2.

 - An icon-only pane button immediately before the tabs cycles three panes, two panes, and content-only. The folder pane alone owns the active root display and folder picker; `⌘1` remains a keyboard return path but is not shown as a badge on the switcher.
 - The folder tree root and root move destination use the selected directory basename; never present a hardcoded `Library` default.
 - Human keeps its fixed-height 78px two-row Source Card below the space switcher. AI uses a compact pinned-shortcut header followed by a vertically scrollable list of every open root. Each visible path keeps only its final two segments as `…/parent/leaf`; pinned list rows prefix the path with their label, while the header repeats only pinned labels as shortcuts. Every path row exposes a direct `Pin` toggle: unpinned is muted but enabled, pinned uses the current AI accent; pinning opens the existing label input before activation and clicking an active pin immediately unpins. The ellipsis menu contains only `Edit label` for pinned roots or `Close` for unpinned roots, plus targeted `Refresh` when unavailable. Pin moves a tab to the end of the pinned group, Unpin moves it to the front of the unpinned group without removing its session, and Edit label preserves root/session identity. Only unpinned tabs can close, removing that root-local session without touching disk files. Exact duplicate roots activate the existing tab; arbitrary visible non-symlink canonical roots, including ancestor/descendant pairs, are allowed. Root activation and close use the save barrier, while pin, unpin, and label edits only persist list transformations. The two-pane navigation fallback retains the AI controls; content-only does not.
-- AI uses root-local one-line document tabs without a source badge; tooltip and accessible name retain the canonical full path. The AI rendered view opens with a muted fixed-font `…/parent/file.md` document-path line above the body that scrolls with the content, keeps the canonical full path as tooltip, and ends with the document's on-disk modified time so reloads make file updates visible; Human mode and PDF export omit it. The AI Explorer mixes folders and Markdown files under the selected root; folder activation selects and expands/collapses the branch, while file activation opens a tab and selects its parent folder. Restoring an active AI session applies the same parent-folder selection. The middle Document List shows only direct Markdown children of the selected folder, marks the active document selected, and keeps that row visible after document, snippet, density, or pane-size changes without moving focus. Folder selection, expanded-tree state, and root availability are runtime-only per root. A missing root keeps its folder tab, optional label, and saved session; targeted Refresh activates it only after a successful scan.

While the git status filter is `Modified+New`, `Modified` (differs from HEAD), or `New` (path missing from HEAD), the Explorer keeps only matching files and the folders above them, fully expanded, and the Document List shows matches anywhere below the selected folder with a muted relative parent path; a selected folder the filter hides reads as the root, and returning to `All` restores the pre-filter selection and expansion. Git status is read with each AI scan (Refresh, root activation, post-mutation rescan) and when leaving `All`, never after saves; `All` only checks for a work tree. Folder selection, expanded-tree state, git filter, and root availability are runtime-only per root. A missing root keeps its folder tab, optional label, and saved session; targeted Refresh activates it only after a successful scan.
 - `⌘1` toggles folders while the list is visible; `⌘2` toggles list plus folders.
 - `⌘F` and `Ctrl+F` open a non-modal current-document Find overlay when an active document exists. Search is case-insensitive literal matching over the current Markdown body only; Enter/Shift+Enter and the next/previous buttons wrap through results, while Escape closes the overlay and restores the prior focus. Human/AI Edit/View/Split reflect the same active result without persisting search state or scanning the workspace.
-- The document list has a global `documentDensity` shared by Human and AI and persisted in `settings.json`: Full shows title, up to two snippet lines, and updated date; Medium shows title and one snippet line; Simple shows title only. Its header cycles `Full → Medium → Simple → Full` with `Rows4`/`Rows3`/`Rows2` between the latest/title sort toggle and create. Human uses `Refresh → Sort → Density → Create`; AI uses the same `Refresh → Sort → Density → Create` order regardless of pin state; its Create button reads `New document`, creates in the selected folder through the shared NameDialog, opens the new document in Edit, and is disabled while the active AI root is unavailable. Opening another AI folder stays in the AI Source Card `FolderPlus` button and the empty content state. Folder rows have no numeric counts. The global `documentSort` preference remains shared by Human and AI and persisted.

 - Settings has separate Appearance, Typography, and Language navigation. Appearance offers Light (default), Two-Tone, Dark, and System themes plus Classic, Terracotta & Teal, Plum & Moss, and Mono Duo Human/AI color palettes in independent 2×2 radio-tile groups; both choices apply immediately and persist independently. The persisted Two-Tone key remains `charcoal`, System follows the OS color mode, and the default palette key is `classic`. Typography offers Sans-serif (default) and Serif in 2-column cards with a live preview; it applies only to Markdown editing/reading and large empty-state copy while application chrome remains Sans-serif. Language offers English (default) and 한국어 in the same 2-column card pattern with a localized live preview, applies immediately across application chrome, and persists in `settings.json`. User filenames, folder names, Markdown titles, and Markdown bodies are never translated. The visible Settings button lives at the navigation bottom: folder pane in three-pane mode, document-list pane in two-pane mode, and nowhere in content-only mode. Settings has no keyboard shortcut.
