+### Product analytics (mandatory for meaningful features)
+
+New features should almost always emit a PostHog event so we can see whether users actually discover and use them. Skip instrumentation only for very small changes where a dedicated event would create noise. Use clear, stable event names, avoid PII or note content, and include only safe metadata that helps evaluate adoption and failures.

 Pre-commit and pre-push hooks enforce **Hotspot Code Health** and **Average Code Health** ≥ thresholds in `.codescene-thresholds`. Both gates block commit/push. Thresholds are a **ratchet** — only go up. When pre-push sees improved remote scores, it updates `.codescene-thresholds`, stages it, and stops so you can commit the new floor with normal verified hooks before pushing again.

 - 🔬 **Open source** — Tolaria is free and open source. I built this for [myself](https://x.com/lucaronin) and for sharing it with others.
 - 📋 **Standards-based** — Notes are markdown files with YAML frontmatter. No proprietary formats, no locked-in data. Everything works with standard tools if you decide to move away from Tolaria.
 - 🔍 **Types as lenses, not schemas** — Types in Tolaria are navigation aids, not enforcement mechanisms. There's no required fields, no validation, just helpful categories for finding notes.

+Asset previewability is inferred in the renderer from the filename extension (`src/utils/filePreview.ts`) rather than stored as a new persisted kind. Supported images render through `<img>` and supported PDFs render through the webview's PDF object renderer, both backed by Tauri asset URLs. Runtime asset access is accumulated only for vault roots Tolaria has loaded in the current app session, because Tauri directory forbids cannot be safely reversed after a vault switch. The "open in default app" action re-enters the active-vault command boundary through `open_vault_file_external` before delegating to the native opener. This keeps the filesystem as source of truth and avoids converting assets into proprietary objects.
+
+### Note Content Freshness
+
+The renderer may cache recently opened or preloaded markdown content, but cached content is only a performance hint. `useTabManagement` can reuse cached text immediately when it carries the same `modifiedAt` and `fileSize` identity as the current `VaultEntry`; otherwise it validates the cached string with the `validate_note_content` Tauri command. That command re-enters the same vault path boundary checks as `get_note_content` and compares the cached text against the current on-disk file bytes. A mismatch, missing file, or unreadable file falls back to the normal fresh-read path and existing missing/unreadable recovery.
+
+`useEditorTabSwap` may reuse BlockNote blocks that were already opened successfully or warmed from prefetched raw content, keyed by vault, path, and exact source content. Background warming is limited to likely next large Markdown notes and defers while the editor is unmounted, raw mode is active, or recent typing/navigation is still inside the foreground idle window. Every async editor swap carries a generation and source-content token so stale conversion results cannot overwrite newer file content or dirty editor state.

+- `FolderTree` keeps the folder interaction surface decomposed into `FolderTreeRow`, `FolderNameInput`, `FolderContextMenu`, and disclosure/context-menu hooks so nested row rendering, inline rename, and right-click actions stay isolated. The UI wraps backend folder nodes in a synthetic vault-root row with `path: ""` and `rootPath` set to the opened vault so root-level files can be listed without turning the vault root into a mutable folder. Non-mutating reveal/copy-path menu items stay callback-driven from `App` so filesystem convenience actions do not leak into folder mutation hooks.
+- `src/components/sidebar/sidebarHooks.ts` owns the shared sidebar interaction primitives for menu positioning/dismissal and inline rename input behavior. Folder, Type, and saved View rows keep their domain-specific actions local, but use those primitives so right-click menus and rename fields have the same outside-click, Escape, focus, blur, and submit semantics.
 - `useFolderActions()` composes `useFolderRename()` and `useFolderDelete()` to keep folder mutations selection-aware while the rest of `App.tsx` only wires the resulting callbacks into `Sidebar` and the command registry.
 - `useNoteRetargeting()` is the shared retargeting abstraction for note drops and command-palette actions. It owns the "can drop here?" checks, updates `type:` via frontmatter when a note lands on a type section, and delegates folder moves through the same crash-safe rename pipeline used by the backend rename commands.
 - A successful folder rename reloads the folder tree plus vault entries, rewrites any affected folder-scoped tabs, and updates `SidebarSelection` to the new relative path when the renamed folder stays selected.
 - Folder deletion clears pending rename state, confirms destructive intent, drops affected folder-scoped tabs, reloads vault data, and resets folder selection if the deleted subtree owned the current selection.
 
+### Saved Views
+
+Saved Views live as YAML files under `views/`. Their definition includes user-visible fields (`name`, `icon`, `color`), note-list preferences (`sort`, `listPropertiesDisplay`), filters, and an optional top-level `order` number. The `order` value is stored directly in the YAML document, not in Markdown frontmatter, and lower values render earlier in every saved-View list. Views without an explicit order sort after ordered views by filename for stable fallback behavior.
+
+The renderer uses `viewOrdering` helpers to convert drag or command-palette move intent into dense order updates before saving each affected view file through `save_view_cmd`. The sidebar treats saved View rows like Type rows for direct customization: double-click starts inline rename, right-click opens edit/rename/icon-color/delete actions, and keyboard users can open that same menu from the focused row while command-palette actions remain responsible for saved View ordering.

+## Command Surface

+`src/shared/appCommandManifest.json` is the cross-runtime source for stable app command IDs, menu structure, display labels, accelerators, deterministic shortcut QA metadata, and native menu enablement groups. The renderer imports it through `src/hooks/appCommandCatalog.ts`, which derives `APP_COMMAND_IDS`, shortcut lookup maps, Linux titlebar menu sections, native-menu command membership, and test helpers. Tauri includes the same JSON in `src-tauri/src/menu.rs` and uses it to build custom menu items, emit overridden menu item IDs such as the quick-open alias as their primary command IDs, and toggle state-dependent menu items from manifest groups.
+
+Domain command builders still own context-sensitive command-palette entries, availability, and execution callbacks.

Controls that BlockNote can render temporarily but Tolaria cannot faithfully persist, such as underline, color, alignment, and the block-type dropdown, are hidden instead of appearing to work and later disappearing.

The side menu aligns itself to the first rendered text line for the hovered block, so H1/H2 typography, line-height, wrapping, and theme changes do not need per-heading offsets. Block reordering uses a Tolaria-owned pointer gesture and direct BlockNote block moves instead of HTML5 `DataTransfer`, keeping it independent from Tauri's native file-drop system. Block-handle actions re-resolve the current live BlockNote block before mutating or dragging, so note reloads and sync churn cannot leave controls acting on stale block references.
+- BlockNote's table row/column handles are patched so stale or missing hovered-table state cancels the drag and hides handles instead of throwing. Add/remove row and column actions also validate the table position and cell indexes before resolving a ProseMirror `CellSelection`, so reloads or menu lag cannot turn stale handles into invalid table-selection positions. Checklist checkbox handlers also re-resolve the live block before updating `checked`, making delayed clicks after note reloads a no-op instead of a stale block mutation. Browser and native table regressions should exercise row and column dragging plus add-menu actions because the state is tracked per orientation.

+Rich-editor change events are coalesced before this serialization runs. `useEditorTabSwap` keeps the latest BlockNote state in the editor, schedules one Markdown serialization for a short idle window, and exposes an explicit flush hook for save, note switch, raw-mode entry, and destructive note actions. This keeps long notes from paying full-document Markdown serialization on every keystroke while preserving the disk-first save path.

+Autosave then waits for a 1.5s idle window before invoking `save_note_content`.

 Current-note find/replace is intentionally backed by raw CodeMirror mode. `Cmd+F`, "Find in Note", and "Replace in Note" switch the active Markdown/text note to raw mode, show the compact find bar above CodeMirror, and operate on the current note only. Plain text matching is case-insensitive by default, `Aa` toggles case sensitivity, `.*` toggles JavaScript-regex matching, and regex replacement supports capture groups through JavaScript replacement syntax.
 
+### Rich Editor Width Modes
+
+Rich Markdown editing supports `normal` and `wide` note widths. The effective mode is resolved in `App.tsx` from, in order, the current session's transient note-width cache, `VaultEntry.noteWidth` parsed from `_width`, and the installation-local `settings.note_width_mode` default. The breadcrumb toggle calls the same setter exposed through the command palette.
+
+Per-note width is persisted as hidden `_width` frontmatter only when the note already has a valid or empty frontmatter block. Notes without frontmatter use the transient cache for the current session, so toggling width never creates frontmatter solely to store UI state. The width class is applied around `SingleEditorView` only; raw CodeMirror mode stays outside `.editor-content-wrapper` and remains full-width.

Large folder filtering runs on the blocking Tokio pool and drains `git check-ignore` output while feeding stdin so broad ignore matches cannot freeze the native UI thread.
 
 #### External Change Detection
 
 The main window starts a native watcher for the active vault through `start_vault_watcher` / `stop_vault_watcher` (`src-tauri/src/vault_watcher.rs`, backed by Rust `notify`). The watcher emits `vault-changed` events for content paths and ignores churn from `.git/`, `node_modules/`, temp files, and `.tolaria-rename-txn`. `useVaultWatcher` batches those events, suppresses recent app-owned saves, and sends the remaining external paths through `refreshPulledVaultState()` so folders, saved views, note-list state, and the clean active editor all refresh under the ADR-0071 unsaved-edit rules. `useVaultLoader.isReloading` drives the status-bar reload spinner for both manual and watcher-triggered reloads.
 
+#### Progressive Vault Loading
+
+Vault opening is allowed to render the main app shell while the full entry scan is still in flight. `useVaultLoader` keeps `isLoading` true until entries are ready, but folders and saved views load independently so the sidebar can become useful before the note index completes. The status bar uses the vault activity badge during this initial indexing state, while command-palette and editor-shell interactions remain mounted instead of being hidden behind the full app skeleton. The full skeleton is reserved for app-level capability checks such as the initial Git-state probe.
+
+Large-vault reproduction and keyboard QA steps live in [LARGE-VAULT-LOADING-QA.md](./LARGE-VAULT-LOADING-QA.md).
+
+#### Note Opening Fast Path
+
+Note opening uses bounded in-memory fast paths for raw content and parsed editor blocks. `useTabManagement` owns the markdown/text prefetch cache and treats every cached value as a performance hint only: identity-matched entries (`modifiedAt` + `fileSize`) can be reused immediately, while identity-missing or identity-mismatched cached text is checked with `validate_note_content`, which compares the cached text with the current file bytes inside the validated vault boundary. If validation fails, Tolaria discards the cached entry and reads fresh disk content before swapping the editor.
+
+The note list opportunistically preloads visible and adjacent markdown/text entries after a short delay. When a large warmed Markdown note resolves, `useEditorTabSwap` may parse it into a bounded parsed-block cache only after foreground editor work has been idle and the rich editor is mounted. Parsed blocks are keyed by vault, path, and exact source content; every async swap carries a generation/source-content token so stale conversion results cannot overwrite newer file content or dirty editor state. The editor never renders a preview surface that later morphs into BlockNote. See [ADR-0105](./adr/0105-editor-correctness-and-responsiveness-contract.md).

The folder tree supports inline folder creation and rename, exposes a right-click menu for rename/delete plus filesystem reveal/copy-path actions, and auto-expands ancestor folders when the current selection or rename target is nested.

Decomposed into `Editor` (orchestrator), `EditorContent`, `FilePreview`, `EditorRightPanel`, `SingleEditorView`, with hooks `useDiffMode`, `useEditorFocus`, and `useEditorSave`, plus the `useRawMode`/`RawEditorView` pair for markdown source editing.

+- **Sidebar** (220-400px, resizable): Top-level filters (All Notes, Changes, Pulse), saved Views, collapsible type-based section groups, and a dedicated folder tree. The folder tree starts with a vault-root row labeled from the opened vault path, shows root-level files when selected, and nests user-created folders plus default vault folders such as `attachments/` and `views/` underneath it; only the dedicated `type/` directory stays hidden because note types already have their own sidebar section. Saved Views persist a top-level YAML `order` field in each view file and use the same ordered-list mental model as Types: pointer users can drag the existing view row, double-click to rename it, or right-click for edit/rename/appearance/delete actions, while keyboard users can use the row context key for the same menu and command-palette move actions for ordering. The folder tree supports inline folder creation and rename, exposes a right-click menu for rename/delete plus filesystem reveal/copy-path actions on mutable folders, and auto-expands ancestor folders when the current selection or rename target is nested. Type sections and folder rows also act as note drop targets: dropping a note on a type updates its `type:` frontmatter, while dropping it on a folder runs the same crash-safe move path as the command palette flow. Each type can have a custom icon, color, sort, and visibility set via its `type: Type` document; new type documents created by Tolaria are written at the vault root.

Can toggle to diff view (modified files), raw CodeMirror view, or a wide rich-editor reading surface with preserved side margins; raw CodeMirror remains full-width and unaffected by note width mode. Inline rich-editor images open in a localized shadcn lightbox on double-click while normal single-click BlockNote selection remains untouched, and tiny tracking-style images are ignored. Binary image and PDF files render through `FilePreview` as ordinary vault files using Tauri asset URLs; external-open actions call `open_vault_file_external` so the target is validated against the active vault before the native default app opens it.

The Sparkle icon in the breadcrumb bar toggles between them. Per-note `icon` is a suggested Inspector property and the command palette's "Set Note Icon" action opens that field directly. When viewing a Type note, the Inspector shows an **Instances** section listing all notes of that type (sorted by modified_at desc, capped at 50).

+Panels are separated by `ResizeHandle` components that support drag-to-resize. `useLayoutPanels` clamps the sidebar, note-list, and inspector widths before applying them, keeps the side panes from flex-shrinking below their protected widths, and persists the last chosen widths in installation-local localStorage under `tolaria:layout-panels`.

That same native command also grows the current window back out when a wider pane combination is restored, while note windows skip this path and keep their dedicated 800×700 initial sizing.

 The main Tauri window also persists its last normal size and screen position in the app config directory as `window-state.json`. The state stores logical window points, while `window_state.rs` migrates older physical-pixel state on read so Retina and non-Retina launches restore the same user-facing bounds. On startup, the restored frame applies only to the main window and clamps to the currently available monitor work areas, so stale coordinates from a disconnected display fall back to a visible placement. Maximized, fullscreen, minimized, and detached note-window frames are not written as the restore baseline.

-When Tolaria is launched from a Linux AppImage, `run()` also injects `WEBKIT_DISABLE_DMABUF_RENDERER=1` unless the user already set that variable. This keeps the workaround scoped to bundled WebKitGTK launches that are prone to Fedora/Wayland DMA-BUF crashes without changing native package installs.
+Tauri setup keeps launch-time filesystem and subprocess work off the window creation critical path. Legacy `~/Laputa` housekeeping and the initial persisted-vault MCP bridge sync run on named background threads, so large legacy vaults, stale active-vault paths, or slow process startup cannot beachball the macOS app before React mounts. React still resyncs the bridge from `useVaultSwitcher` after the persisted selection loads, and no selected vault stops the bridge. The HTML bootstrap also installs a Tauri-only one-shot watchdog: React reports readiness from an effect after the root commits, and if that readiness signal never arrives the WebView reloads once instead of leaving macOS users in an inert rendered shell.

+When Tolaria is launched from a Linux AppImage, `run()` also applies AppImage-only WebKitGTK startup safeguards without changing native package installs. It injects `WEBKIT_DISABLE_DMABUF_RENDERER=1` and `WEBKIT_DISABLE_COMPOSITING_MODE=1` independently unless the user already set either variable, and on Wayland sessions it re-execs once with the first architecture-matching system `libwayland-client.so` in `LD_PRELOAD` when the user has not provided their own preload. The candidate order prefers Fedora-style `lib64` and Debian-style `x86_64-linux-gnu` paths before generic `/usr/lib`, and the ELF header is checked so a 64-bit Tolaria process does not retry with a 32-bit Wayland client library. The same AppImage path checks whether `fc-match` resolves the default emoji font to `Noto-COLRv1.ttf`; when the user has not provided `FONTCONFIG_FILE` or `FONTCONFIG_PATH`, Tolaria writes a cache-local fontconfig file that rejects only that matched font file and exports it before WebKit starts. The rendering overrides keep AppImage WebViews from blanking after accelerated compositing/DMA-BUF failures, the re-exec addresses AppImage library-order failures that can surface as `Could not create default EGL display: EGL_BAD_PARAMETER`, and the fontconfig guard avoids known WebKit crashes in COLRv1 emoji font rendering while leaving other emoji fonts available.

+### Direct Model Targets
+
+Tolaria also supports direct model targets for local servers and API providers. These targets are stored as app-level provider metadata and can be selected in Settings or the status bar alongside coding agents. Direct model targets run in Chat mode: they receive the same note-context snapshot and conversation history, but they do not receive vault-write tools or shell access. The backend `stream_ai_model` command supports OpenAI-compatible chat completions and Anthropic Messages-compatible calls, including Ollama, LM Studio, OpenRouter, OpenAI, Anthropic, Gemini, and custom compatible endpoints.
+
+Provider secrets are not written to `settings.json`. Hosted API targets can use Tolaria's local app-data secrets file (`ai-provider-secrets.json`, outside vaults/worktrees and owner-only on Unix) or reference an environment variable name. Local endpoints can omit authentication.
 
 ### Authentication

Tolaria does not store model-provider API keys in app settings.

In the desktop app, `useMcpStatus` copies that snippet through the native `copy_text_to_clipboard` command instead of the Web Clipboard API so macOS WKWebView permission policy cannot block setup. Packaged builds resolve `mcp-server/` from the installed resource directory next to the executable before falling back to macOS `Resources`, Linux package roots such as `/usr/local/Tolaria`, `/usr/lib/tolaria`, and `/usr/lib/tolaria/resources`, and AppImage paths. The `useMcpStatus` hook tracks whether the active vault is explicitly connected (`checking | installed | not_installed`) and owns connect, disconnect, exact-snippet load, and copy-to-clipboard actions. Gemini CLI still owns its own install and sign-in; Tolaria writes the durable external MCP entry only on explicit setup, while app-managed Gemini sessions use transient settings and optional vault guidance.

Stdio MCP server processes are owned by the external client that launched them: when that client closes stdin, Tolaria cancels UI-bridge reconnect timers, closes any UI WebSocket, and exits the Node process instead of keeping it alive in the background.

 When an opened folder is not yet a git repo, Tolaria shows a dismissible Git setup dialog and a persistent `Git disabled` status-bar warning. Markdown scanning, note browsing, note editing, and search continue normally. Git-dependent surfaces (history, changes, commit, sync, conflict resolution, remotes, AutoGit, and auto-sync) stay unavailable until the user explicitly initializes Git from the dialog, the status-bar warning, or the `Initialize Git for Current Vault` command-palette action.
 
 When the user enables Git later, `init_git_repo` runs `git init`, ensures Tolaria's default `.gitignore`, stages the vault, and writes the initial `Initial vault setup` commit. Before app-managed setup and remote-connection commits, Tolaria ensures the vault has local `user.name` / `user.email` values, falling back to `Tolaria <vault@tolaria.md>` when the vault has no local Git identity yet. That app-managed setup commit explicitly disables commit signing for the single command so inherited global or local `commit.gpgsign` preferences cannot strand onboarding when GPG is missing or misconfigured. Later `git_commit` calls honor the user's signing configuration first, then retry the same app-managed commit once with `commit.gpgsign=false` only when Git reports a signing-helper failure, so working GPG/SSH signing setups continue to sign while broken GPG setups do not create repeated opaque commit failures.
 
-Once a vault is ready, `useAiAgentsOnboarding` can show a one-time `AiAgentsOnboardingPrompt`. That prompt reads `useAiAgentsStatus` so first launch surfaces whether Claude Code, Codex, OpenCode, and Pi are installed, offers per-agent install links when they are missing, and stores local dismissal so the prompt does not repeat on every launch.

The clone helper still accepts the legacy `LAPUTA_GETTING_STARTED_REPO_URL` environment override so older automation can continue to redirect the starter source during the transition.

+Recent Tolaria AppImages automatically disable unstable WebKitGTK AppImage rendering paths and retry startup with an architecture-matching system Wayland client library when they detect this class of AppImage + Wayland environment. If you are running an older build, use this workaround:

+
+If your distribution stores the 64-bit library elsewhere, use that path instead, for example `/usr/lib/x86_64-linux-gnu/libwayland-client.so.0`. On 64-bit Fedora, avoid `/usr/lib/libwayland-client.so.0`; that path can point at a 32-bit library and be ignored by the loader with a wrong ELF class warning.

+title: "Gemini CLI external AI setup"
+status: active
+date: 2026-04-28
+---
+
+## Context
+
+Tolaria already supports explicit MCP setup for external desktop AI tools. Users asked for Gemini CLI support so the same active-vault MCP server can be registered where Gemini reads tool configuration, with optional Gemini-specific vault guidance.
+
+Gemini CLI reads MCP server definitions from `~/.gemini/settings.json` and can load project guidance from `GEMINI.md`. Tolaria must support those conventions without silently rewriting global user settings or overwriting user-authored vault instructions.
+
+## Decision
+
+Tolaria adds `~/.gemini/settings.json` to the explicit external AI setup path list. The existing MCP entry shape is reused: `mcpServers.tolaria` runs the packaged stdio server through Node.js, pins `VAULT_PATH` to the selected vault, and sets `WS_UI_PORT=9711`.
+
+Vault guidance keeps `AGENTS.md` as the canonical shared source. `restore_vault_ai_guidance` can create or repair a managed `GEMINI.md` shim that imports `AGENTS.md`, while bootstrap and repair flows continue to seed only required Tolaria guidance (`AGENTS.md` and `CLAUDE.md`) plus type scaffolding. Custom `GEMINI.md` files are classified as custom and are not overwritten.
+
+The setup dialog documents that Gemini CLI still needs its own install and sign-in. Tolaria does not store Gemini credentials or model-provider API keys.
+
+## Options Considered
+
+- **Add Gemini to explicit MCP setup and optional guidance restore** (chosen): matches the existing consent boundary, preserves user settings, and gives Gemini the shared vault context.
+- **Generate `GEMINI.md` automatically for every vault**: simpler discovery, but turns an optional third-party compatibility file into startup side effect and dirties vaults for users who do not use Gemini.
+- **Document manual Gemini setup only**: avoids code changes, but leaves users to transpose paths and loses the active-vault safety already available for other MCP clients.
+- **Create a Gemini-specific MCP entry shape**: unnecessary because Gemini accepts the same `mcpServers` entry structure used by the existing Tolaria MCP server.
+
+## Consequences
+
+- External AI setup now writes/removes Tolaria's MCP entry in Claude, Gemini, Cursor, and generic MCP config files.
+- Gemini users can create a managed `GEMINI.md` shim without duplicating the canonical `AGENTS.md` guidance.
+- Existing vault bootstrap and repair remain non-invasive for users who do not use Gemini.
+- Native QA requires a local Gemini CLI install and authentication for an end-to-end Gemini prompt; otherwise the app can still verify the generated config and documentation paths.

+title: "Vault-scoped AI agent permission modes"
+status: active
+date: 2026-04-28
+---
+
+## Context
+
+ADR-0074 established explicit setup and least-privilege defaults for desktop AI tools. The in-app AI panel now supports multiple local CLI agents, and users need a clear per-vault way to choose whether an agent should stay in the narrow vault-safe profile or use broader local-work tools for that vault.
+
+The mode must be visible at the point of use, must not mutate global CLI settings, and must not silently restore dangerous bypass flags. Existing transcripts should remain intact when the mode changes because a change applies to the next agent run, not to a process that is already streaming.
+
+## Decision
+
+**Tolaria stores an `ai_agent_permission_mode` per vault with values `safe` and `power_user`, defaulting missing or null values to `safe`, and passes that normalized mode through the AI panel stream request into each CLI adapter.**
+
+The AI panel header displays the current mode and offers a compact Vault Safe / Power User control that is disabled while an agent run is active. Changing the mode preserves the transcript and inserts a local transcript marker.
+
+Adapter mappings remain conservative:
+- Claude Code Safe keeps `acceptEdits`, strict Tolaria MCP config, and file/search/edit tools only; Power User adds Bash to the allowed tool list without using `--dangerously-skip-permissions`.
+- Codex keeps the active-vault `workspace-write` sandbox and `--ask-for-approval never` in both modes.
+- OpenCode uses transient `OPENCODE_CONFIG_CONTENT`; Safe denies bash and external directories, while Power User allows bash but still denies external directories.
+- Pi receives the mode on the adapter request path; both modes currently use the same transient MCP adapter config.
+
+## Options Considered
+
+- **Per-vault Safe / Power User modes** (chosen): makes the permission surface explicit where the agent is used and preserves least-privilege defaults for each vault.
+- **Global app setting**: simpler storage, but a single toggle can over-apply a power-user profile to unrelated vaults.
+- **Dangerous bypass mode**: maximizes CLI freedom, but violates ADR-0074's least-privilege boundary and needs a separate explicit security decision.
+- **Adapter-specific UI switches**: exposes too much implementation detail and makes cross-agent behavior harder to reason about.
+
+## Consequences
+
+- Vault config normalization owns the safe default for old vaults and malformed values.
+- Agent requests now carry a permission mode through frontend and Rust boundaries, so new adapters must choose an explicit mapping.
+- Power User is intentionally not equivalent across agents; where an adapter lacks a safe broader local-work switch, both modes may map to the same conservative behavior and must document that with tests.
+- Any future dangerous mode requires a new ADR and separate UI language.

+---
+
+## Context
+
+Tolaria supports Claude Code, Codex, OpenCode, and Pi as local CLI agents in the AI panel. Each agent has different command-line arguments, configuration shape, and JSON event schema, but the Rust backend had grown repeated runtime plumbing around those differences: request shapes, prompt wrapping, subprocess launch, stdout JSON reading, stderr capture, exit handling, done events, version probing, and Tolaria MCP server path resolution.
+
+That duplication made small runtime fixes expensive because they had to be repeated across several adapter files. It also kept Codex-specific command and event mapping inside `ai_agents.rs`, making the top-level module both an orchestrator and a bespoke adapter.
+
+## Decision
+
+**Tolaria uses `cli_agent_runtime.rs` as the shared runtime scaffold for app-managed CLI agents, while `ai_agents.rs` only normalizes and dispatches requests to per-agent adapter modules.**
+
+The shared scaffold owns the common agent request shape, system/user prompt wrapping, JSON-line process lifecycle, normalized error/done handling for `AiAgentStreamEvent` adapters, version probing, and Tolaria MCP server path resolution. Per-agent modules keep the provider-specific pieces: binary discovery candidates, command arguments, transient config shape, authentication error wording, and JSON event mapping.
+
+Codex now lives in `codex_cli.rs`, matching the Claude, OpenCode, and Pi adapter boundary. `ai_agents.rs` remains the Tauri-facing orchestrator that chooses an adapter and maps Claude's legacy event enum into the normalized event stream.
+
+## Options Considered
+
+- **Shared runtime scaffold with thin adapters** (chosen): reduces repeated process lifecycle code without hiding provider-specific command/config/event behavior.
+- **One trait object per agent**: more uniform on paper, but adds indirection without removing much current complexity.
+- **Leave each adapter self-contained**: keeps local readability for a single file, but new process, prompt, and MCP fixes continue to land in parallel.
+- **Fully generic event mapping**: over-abstracts the JSON schemas and makes provider-specific edge cases harder to test.
+
+## Consequences
+
+- Runtime lifecycle fixes should usually start in `cli_agent_runtime.rs`.
+- New agent adapters should use the shared request/prompt/process helpers and keep only command, config, discovery, and event mapping local.
+- `ai_agents.rs` should not grow provider-specific runtime code again; it should normalize the frontend request, dispatch to an adapter, and map any legacy event shape.
+- The shared scaffold deliberately does not erase provider differences. Authentication messages, permission semantics, and transient config formats remain adapter-owned and must stay covered by adapter tests.

+status: active
+date: 2026-04-29
+---
+
+## Context
+
+Tolaria's vault scanner now indexes more of the real filesystem so Folder views, search, and reload flows can reflect what is actually in the vault. In Git-backed vaults, that includes generated, local-only, or machine-specific content that users intentionally hide through `.gitignore`.
+
+Always showing Gitignored files makes Folder lists and search noisy, especially in vaults that contain exports, build artifacts, or personal local scratch files. But removing those files during scanning would make visibility dependent on cache shape, complicate toggling, and blur the distinction between "what exists in the vault" and "what this installation chooses to surface."
+
+## Decision
+
+**Tolaria keeps the vault scan and cache complete, then applies Gitignored-content visibility at the command boundary before entries, folders, or search results reach React.**
+
+- `hide_gitignored_files` is an installation-local app setting and defaults to `true`.
+- Visibility checks use batched `git check-ignore --no-index --stdin` so Tolaria follows normal Git ignore and negation semantics as closely as practical.
+- `list_vault`, `reload_vault`, `list_vault_folders`, and keyword search all apply the same filter when the setting is enabled.
+- Toggling the setting reloads the current vault surfaces instead of rebuilding a different cache format.
+- If a vault has no `.gitignore`, or Gitignored visibility is turned off, Tolaria shows the full scanned result.
+
+## Options considered
+
+- **Complete scan/cache + boundary filter** (chosen): keeps the filesystem model authoritative, makes toggling cheap and consistent, and avoids cache divergence.
+- **Skip Gitignored content during scan/cache**: reduces later filtering work, but makes visibility part of the persisted cache shape and complicates instant toggling.
+- **Always show Gitignored content**: simplest implementation, but too noisy for real Git-backed vaults and undermines users' existing ignore rules.
+
+## Consequences
+
+- Gitignored visibility is a per-installation comfort preference, not vault-authored shared metadata.
+- Search, folder lists, and note reloads stay aligned because they all consult the same boundary filter.
+- The cache can still support future visibility changes without a data migration.
+- Users can reveal ignored content again immediately by disabling the setting.
+- Future features that expose vault file lists should apply the same boundary filter unless they intentionally need raw filesystem output.

+## Context
+
+Saved Views already persist as user-editable YAML files in the vault and sync through Git. Filename ordering was stable, but it forced users to rename files just to change sidebar order and gave Tolaria no durable way to support drag reordering, move actions, or keyboard-first ordering controls.
+
+The ordering choice also needs to travel with the view definition itself. Saved Views are part of the vault's shared information architecture, not a machine-local preference.
+
+## Decision
+
+**Each Saved View may store an optional top-level `order` number in its YAML definition, and Tolaria sorts views by that value before falling back to filename.**
+
+- Lower `order` values render earlier in the sidebar and other Saved View lists.
+- Views without `order` sort after ordered views and then fall back to filename ordering for stability.
+- Reordering actions rewrite affected view files with a dense sequence of order values instead of encoding position in filenames.
+- The same persisted order supports drag handles, explicit move buttons, and command-palette ordering actions.
+
+## Options considered
+
+- **Explicit `order` field in the view YAML** (chosen): portable, Git-syncable, easy to inspect by hand, and consistent with the existing file-first view model.
+- **Filename-based ordering only**: no schema change, but makes reordering clumsy and couples user-visible structure to file naming.
+- **App-local ordering state**: easy to prototype, but breaks cross-device consistency and separates ordering from the view artifact users already version.
+
+## Consequences
+
+- Saved View ordering becomes part of the vault and syncs naturally through Git.
+- Existing views remain valid; unordered files keep a stable fallback sort until reordered.
+- Reordering can touch multiple view files in one action because Tolaria normalizes the sequence.
+- Future Saved View features should treat `order` as part of the shared YAML schema rather than introducing a parallel ordering store.

+
+## Decision
+
+**Tolaria creates new type documents at the vault root.**
+
+- A type document is any markdown note with `type: Type` in frontmatter.
+- New UI-created type documents use `{vault}/{slug}.md`.
+- Existing type documents in `type/`, `types/`, or other scanned folders remain valid and continue to drive templates, icons, colors, visibility, sorting, and sidebar grouping.
+- Creation does not silently migrate or move existing type documents.
+- Root filename collisions are handled as file collisions; Tolaria must not overwrite an existing note when creating a type document.
+
+## Options considered
+
+- **Root-created type documents** (chosen): matches the metadata-first model, removes special casing from creation, and aligns new types with root-managed default type scaffolding.
+- **Canonical `type/` folder**: avoids root filename collisions, but makes path special even though type identity is already defined by frontmatter.
+- **Preserve existing folder convention dynamically**: minimizes change for plural `types/` vaults, but creates inconsistent behavior across vaults and leaves `types/` only partially supported.
+
+## Consequences
+
+- Users can inspect and edit type documents as ordinary root notes by default.
+- Existing vaults with `type/` or `types/` type documents remain readable because vault scanning already includes non-hidden subdirectories.
+- If a root note with the same slug already exists, type creation fails with a collision message instead of writing into a fallback folder.
+- Legacy `type/` may remain hidden from the folder tree so old type documents do not duplicate the Types sidebar section.

+## Context
+
+ADR 0091 added Gemini CLI to explicit external MCP setup, but Gemini was still absent from Tolaria's selectable app-managed AI agents. That left the AI panel able to generate Gemini-compatible MCP configuration while the actual agent picker, availability checks, install links, and streaming dispatch did not treat Gemini like Claude Code, Codex, OpenCode, or Pi.
+
+Gemini CLI supports headless `--prompt` execution with JSON output, configurable approval modes, tool exclusion, and settings-file overrides through `GEMINI_CLI_SYSTEM_SETTINGS_PATH`. Those features are enough to launch Gemini from Tolaria without mutating the user's durable `~/.gemini/settings.json` during app-managed sessions.
+
+## Decision
+
+Tolaria adds Gemini CLI as a first-class `AiAgentId`. The frontend agent definitions, onboarding prompt, install links, default-agent normalization, status badge, command registry, settings persistence, and mock Tauri status payloads include `gemini`.
+
+The desktop backend adds a Gemini adapter that:
+
+- discovers `gemini` through the process path, login shell, and common local/toolchain install locations
+- runs `gemini --output-format json --approval-mode <mode> --prompt <prompt>` from the active vault
+- supplies Tolaria MCP through a temporary settings file referenced by `GEMINI_CLI_SYSTEM_SETTINGS_PATH`
+- uses Safe mode with `auto_edit`, an untrusted MCP entry, and `tools.exclude=["run_shell_command"]`
+- uses Power User mode with `yolo` and a trusted Tolaria MCP entry
+- maps Gemini JSON responses into Tolaria's existing AI panel stream events
+
+The existing external MCP setup remains explicit and durable. The app-managed Gemini adapter uses transient settings so selecting Gemini in Tolaria does not rewrite the user's global Gemini config.
+
+## Options Considered
+
+- **Add Gemini as a first-class app-managed agent** (chosen): matches the existing agent picker and onboarding UI, uses Gemini's headless JSON mode, and keeps MCP setup vault-scoped.
+- **Keep Gemini as external MCP setup only**: avoids another adapter, but keeps the interface inconsistent and requires users to leave Tolaria for a flow that other agents support in-panel.
+- **Write app-managed Gemini config into `~/.gemini/settings.json`**: reuses the external setup path, but would blur the consent boundary and risk overwriting user preferences during normal AI panel usage.
+- **Use interactive Gemini sessions**: could preserve richer CLI state, but does not fit Tolaria's current one-request stream lifecycle and would make cleanup/auth/error handling harder.
+
+## Consequences
+

+---
+
+## Context
+
+ADR-0086 introduced the `FilePreview` path for image binaries while keeping binary files as ordinary `VaultEntry` records. The same file-first model should now cover PDFs, because asset-heavy vaults often mix screenshots, diagrams, and document exports that users need to inspect without leaving Tolaria.
+
+## Decision
+
+**Tolaria previews supported image and PDF files in the editor pane while keeping them as ordinary binary vault files.**
+
+- The scanner keeps the coarse `fileKind: "binary"` representation. Previewability stays a renderer concern inferred from the file extension in `src/utils/filePreview.ts`.
+- Supported images render with `<img>` and supported PDFs render with the webview PDF object renderer, both using Tauri asset URLs from `convertFileSrc`.
+- The Tauri CSP permits scoped asset URLs in `object-src` so PDF objects can load vault-backed files without broadening script, connect, or image policy.
+- PDF preview fallback content lives inside the PDF object so unsupported or failed renderers still expose an explicit "Open in default app" escape hatch.
+- Note-list rows for previewable images and PDFs remain clickable and carry file-specific indicators; unsupported binary rows stay muted and non-clickable.
+- `Escape` on the preview surface returns keyboard focus to the note list, matching the existing image-preview keyboard behavior.
+
+## Consequences
+
+- PDFs do not become notes and do not get Markdown editor semantics.
+- The asset preview surface can keep growing to additional safe binary formats without changing the vault scanner or persisted cache shape.
+- Broken PDFs may rely on the webview's own renderer failure state, but the surrounding Tolaria preview chrome still provides reveal, copy path, and default-app actions.

+---
+
+## Context
+
+ADR-0074 moved the desktop asset protocol away from broad filesystem access and toward runtime vault scoping. The implementation tried to keep only the active vault in scope by calling Tauri's `forbid_directory` for vault roots that were no longer active.
+
+Tauri's filesystem scope treats forbidden paths as permanent precedence rules: a forbidden path is denied even if it is later allowed again. After a user switched away from a vault and back, image and PDF previews could keep producing `403 Forbidden` responses for valid vault files until the app restarted.
+
+## Decision
+
+**Tolaria accumulates Tauri asset protocol access for vault roots loaded during the current app session and never forbids a previously loaded vault root at runtime.**
+
+- `sync_vault_asset_scope` adds the canonical vault root and requested vault root when they are missing from the runtime asset scope.
+- The runtime asset scope remains narrower than global filesystem access because only vault roots that Tolaria has loaded are added.
+- Command paths still enforce the active vault boundary through the Rust command layer before reads, writes, external opens, and attachment imports.
+- Asset scope revocation is deferred to process exit, because Tauri does not expose a safe runtime unallow operation for directories.
+
+## Options considered
+
+- **Cumulative runtime vault scope** (chosen): keeps previews reliable after vault switches while preserving vault-only access in the current process.
+- **Continue forbidding previous vaults**: appears stricter, but Tauri forbids are not reversible and valid previews fail after switching back.
+- **Allow all filesystem paths**: avoids preview failures but returns to the broad asset protocol access that ADR-0074 intentionally removed.
+- **Replace `convertFileSrc` with a custom protocol**: could support exact active-vault revocation, but it would be a larger cross-cutting migration for editor images, file previews, and PDF rendering.
+
+## Consequences
+
+- Images and PDFs from any vault loaded in the current session can keep rendering after vault switches.
+- The app process, not each vault switch, is the revocation boundary for asset URL access.
+- Active-vault command validation remains the primary guard for mutations and default-app opens.

+---
+
+## Context
+
+ADR-0033 introduced subfolder scanning and a collapsible folder tree backed by `list_vault_folders`, but the sidebar still had no first-class way to select the vault root itself. That left root-level files outside the folder-navigation model and pushed the UI toward one-off handling for the opened vault path.
+
+The new sidebar behavior needs to show root-level files when the user clicks the vault name, while preserving the existing folder rename/delete model for real folders only.
+
+## Decision
+
+**Represent the vault root in the sidebar as a synthetic frontend-owned folder row rather than as a mutable backend folder.**
+
+- `FolderTree` wraps backend folder nodes in a root row with `path: ""` and `rootPath` set to the opened vault path.
+- `SidebarSelection` keeps using `kind: 'folder'`, but root selection is encoded as the empty folder path plus `rootPath` metadata.
+- Root-level file filtering is handled in note-list helpers as a dedicated root case instead of pretending the vault root is an ordinary folder.
+- Rename/delete remain available only for real folders; the vault root row is navigable, not mutable.
+
+## Options considered
+
+- **Option A** (chosen): Synthetic vault-root row in the renderer — keeps `list_vault_folders` focused on real folders, avoids backend schema churn, and reuses the existing folder-selection mental model.
+- **Option B**: Add a pseudo-folder to backend folder results — would couple presentation-only root behavior to command data and blur the distinction between the vault itself and mutable folders.
+- **Option C**: Keep root files outside folder navigation entirely — simpler, but leaves the sidebar with an incomplete navigation model and special cases elsewhere in the UI.
+
+## Consequences
+
+- Folder navigation now has a single model for root and nested folder browsing.
+- Backend folder APIs stay unchanged: they describe actual folders, not UI-only rows.
+- Selection handling must treat `path: ""` as the vault-root case and use `rootPath` when computing direct-root file membership.
+- Re-evaluate if folder actions ever need to operate on the vault root itself, because that would likely require a separate command model instead of extending the synthetic row.

+
+ADR-0016 established opt-in PostHog analytics and Sentry crash reporting, but new feature telemetry now spans file previews, inline image lightbox opens, AI agent session lifecycle events, and All Notes visibility toggles. Instrumenting those flows ad hoc would make it easy to leak vault-specific data such as note paths, filenames, prompt text, or image URLs.
+
+Tolaria needs richer product telemetry for feature behavior while preserving the privacy bar expected from a local-first notes app.
+
+## Decision
+
+**Route product analytics through dedicated helper functions that emit only coarse categorical metadata.**
+
+- Product events live behind `src/lib/productAnalytics.ts` instead of scattering raw `trackEvent()` payloads across feature code.
+- Allowed payloads are constrained to categories and counts such as preview kind, action kind, AI agent id, permission mode, response/tool counts, status, and All Notes visibility category/enabled state.
+- Product events must not include vault content, note titles, file paths, filenames, image URLs, prompt text, or other user-authored data.
+- When a feature needs telemetry, it should add or extend a typed helper rather than sending free-form payloads inline.
+
+## Options considered
+
+- **Option A** (chosen): Typed categorical wrappers for product events — preserves useful product signals while keeping privacy constraints explicit and reviewable in one place.
+- **Option B**: Let each feature call `trackEvent()` directly with whatever fields seem useful — faster short term, but inconsistent and too easy to let sensitive data leak into analytics.
+- **Option C**: Avoid new product events entirely — safest from a privacy standpoint, but leaves the team blind to whether preview, AI, and list-visibility features are actually being used or failing.
+
+## Consequences
+
+- Telemetry reviews become easier because the allowed product-event surface is centralized.
+- Future product analytics work should start by defining categorical event helpers, not by attaching raw note/file context.
+- Some debugging detail is intentionally sacrificed; deep diagnosis should rely on consented crash reporting and local reproduction rather than richer analytics payloads.

+
+## Context
+
+ADR-0015 chose a 500ms autosave debounce so normal edits would persist quickly without writing on every keystroke. GitHub issue #443 showed that this window is too aggressive on very weak Windows CPUs: if typing intervals exceed 500ms or a save takes long enough to overlap continued typing, Tolaria can start disk and derived-state work while the user is still entering text.
+
+## Decision
+
+**Tolaria autosaves after a 1.5s idle window and treats stale in-flight autosaves as obsolete when newer content arrives before they resolve.** Manual saves, note switches, raw-mode entry, and destructive actions still flush pending editor content immediately.
+
+## Options Considered
+
+- **Option A — 1.5s idle window plus stale-save protection** (chosen): reduces mid-typing saves on slow CPUs while keeping ordinary autosave behavior fast enough for reliability. It also prevents an older slow save from clearing or repainting over newer pending text.
+- **Option B — Keep 500ms and only fix stale saves**: preserves the previous timing but still triggers repeated saves for slower typists and weaker machines.
+- **Option C — Save only on blur or navigation**: minimizes background work but increases crash-loss risk during longer writing sessions.
+
+## Consequences
+
+- Autosave is less likely to compete with active typing on low-end Windows hardware.
+- The unsaved window grows from roughly 500ms to roughly 1.5s after Tolaria receives the latest content change.
+- Explicit flush paths remain immediate, so navigation, manual save, raw-mode transitions, and destructive actions still preserve pending edits before proceeding.
+- Future changes to autosave timing should keep weak-CPU responsiveness and stale in-flight save behavior in the same test surface.

+ADR-0092 introduced per-vault Vault Safe / Power User modes, but the first implementation left too much room for adapter drift. Some agents can directly deny or allow Bash, some expose only a sandbox/approval profile, and Pi currently has no narrower app-managed switch beyond Tolaria's transient MCP configuration. The shared UI still needs a consistent product contract: Vault Safe must not encourage shell execution, while Power User should keep shell execution available across repeated agent turns where the selected adapter supports it.
+
+## Decision
+
+**Tolaria treats the permission mode as a product contract first and maps it conservatively per adapter.**
+
+- Shared AI system prompts are mode-aware on every turn, including turns with note context snapshots.
+- Vault Safe tells agents not to use or advertise shell, terminal, Bash, script execution, git, or command-line tools.
+- Power User tells shell-capable agents that local shell commands are available for the active vault and should remain scoped to that vault.
+- Claude Code Safe excludes Bash; Power User includes and pre-approves Bash without dangerous bypass flags.
+- Codex Safe uses the CLI's read-only sandbox plus untrusted approval policy; Power User uses workspace-write plus never-ask approval so shell-capable Codex turns remain low-friction across the session.
+- OpenCode Safe denies bash and external directories; Power User allows bash while still denying external directories.
+- Pi keeps the same conservative transient MCP config in both modes until the Pi CLI exposes a reliable app-managed shell permission switch. The prompt must not promise shell for Pi Power User.
+- Gemini Safe excludes `run_shell_command`; Gemini Power User intentionally uses `yolo` with trusted transient Tolaria MCP settings.
+
+## Consequences
+
+- Mode behavior is no longer described solely by generic UI copy; adapter docs and tests define the exact mapping.
+- Codex Vault Safe remains a best-effort safe profile rather than a true built-in-tools-off mode, because Codex CLI currently exposes sandbox and approval controls but not a dedicated switch to remove shell tooling while preserving MCP.
+- Future adapters must either implement both modes explicitly or document that Power User maps to the same conservative behavior.

+---
+
+## Context
+
+Tolaria already keeps heavy filesystem and subprocess work off the Tauri window-creation path, but that alone does not protect against a different startup failure mode: the desktop WebView can render the static HTML shell while the React app never becomes interactive.
+
+On macOS this showed up as an inert window that looked launched but never finished mounting the real app. The failure boundary is cross-layer:
+
+- `index.html` can paint before React commits
+- React root errors can happen before the app reports itself ready
+- a plain reload is acceptable as a one-time recovery, but an automatic reload loop is not
+- browser/mock runs should not inherit desktop-only recovery behavior
+
+Tolaria needs a startup contract that distinguishes “HTML painted” from “frontend actually became interactive”, and a bounded recovery path when that contract is not satisfied.
+
+## Decision
+
+**Tolaria uses a Tauri-only frontend-readiness watchdog that reloads the WebView at most once if React never reports startup readiness.**
+
+Concretely:
+
+- `index.html` installs a Tauri-only startup timer before React loads
+- React dispatches a readiness signal from a mounted effect after the app shell commits
+- if readiness never arrives before the timeout, the WebView reloads once
+- the same one-shot reload path is available to React root error handling before readiness is marked
+- `sessionStorage` tracks whether the startup reload was already attempted so Tolaria does not loop forever
+- browser/mock environments keep using ordinary browser clipboard/storage behavior and do not enable this desktop startup recovery path
+
+## Options considered
+
+- **Tauri-only readiness watchdog with one-shot reload** (chosen): directly addresses the inert-startup failure mode, keeps recovery local to the frontend, and avoids permanent reload loops. Cost: startup now depends on a small cross-layer contract between HTML bootstrap and React.
+- **Do nothing and rely on manual relaunch**: simplest implementation, but leaves users stranded in a broken-looking app state with no automatic recovery.
+- **Reload on any React root error without a readiness gate**: more aggressive, but too noisy; post-startup runtime errors should not trigger surprise reloads.
+- **Move recovery entirely into native Rust window/bootstrap logic**: possible, but the failure signal lives in the frontend lifecycle, so native code would still need a readiness handshake.
+
+## Consequences
+
+- Tolaria now distinguishes successful frontend startup from merely rendering the HTML shell.
+- Desktop startup recovery is bounded to a single retry per session, reducing the chance of trapping users in reload loops.
+- `index.html`, `src/main.tsx`, and `src/utils/frontendReady.ts` form a shared startup contract that future bootstrap refactors must preserve.
+- Any future change that delays app-shell mount beyond the watchdog timeout must re-evaluate the timeout and readiness trigger.
+- If a startup failure persists after one retry, Tolaria still surfaces the broken state instead of hiding a deeper bug behind repeated reloads.

+## Context
+
+Tolaria notes are durable Markdown files on disk, but the rich editor renders them through BlockNote blocks. Large notes exposed a tempting optimization: show a fast Markdown preview first, then hydrate BlockNote later. In practice, that creates two renderers for the same document, visible flicker, delayed click-time lag, and more places for stale async work to race with the currently selected note.
+
+The editor must optimize for the product priorities in this order:
+
+1. no crashes
+2. no stale content, race-condition overwrites, or lost edits
+3. responsive typing and cursor movement
+4. fast note-list-to-editor loading
+
+## Decision
+
+**Tolaria keeps a single direct editor surface for Markdown notes and treats editor content swaps as generation-checked, source-content-checked operations.** Fast loading may use raw file-content prefetching and a bounded parsed-block cache, but it must not show a separate preview that later swaps into the editor. Parsed BlockNote blocks are reusable only when their source Markdown exactly matches the content being opened, and background parsing must run only after recent typing/navigation has gone idle.
+
+## Options considered
+
+- **Single direct editor surface with guarded swaps plus bounded caches** (chosen): preserves one visual representation of the document, rejects stale async parse results, validates or identity-checks cached disk content before opening, and keeps typing work debounced. Cons: very large notes can still wait on BlockNote conversion when they were not warmed.
+- **Fast Markdown preview followed by hidden BlockNote hydration**: improves first paint but creates flicker, delayed edit-time stalls, and duplicated rendering semantics.
+- **Unbounded or eager background BlockNote parsing for likely next notes**: can make some opens faster, but competes with typing/navigation and introduces stale parse-result hazards unless heavily scheduled, bounded, and invalidated.
+- **Always raw mode for large notes**: strongest responsiveness for huge files, but changes the editing experience abruptly and should be an explicit fallback rather than the default.
+
+## Consequences
+
+- Async editor work must prove it still matches both the latest swap generation and the latest tab source content before touching BlockNote.
+- Cached raw note content must be validated against disk before it is shown unless it carries the same `modifiedAt` and `fileSize` identity as the current `VaultEntry`, or the content was just authored by Tolaria in the current process.
+- Cached parsed BlockNote blocks must be keyed by vault, path, and exact source content, cloned on read/write, and bounded by entry count plus source byte budget.
+- Background parsed-block warming is allowed only for likely next large Markdown notes after a foreground idle window; active typing, raw mode, and editor mount state must defer it.
+- Dirty local editor content remains authoritative. External filesystem refreshes may replace clean notes, but must not overwrite unsaved local edits.
+- Per-keystroke editor work must stay minimal. Serialization, metadata derivation, autosave, and cache updates should be debounced, coalesced, or scheduled away from active typing.
+- Future large-note optimizations should target true progressive/chunked conversion or explicit raw/read-only fallback states, not a visually different preview that morphs into BlockNote.

+
+## Context
+
+Tolaria notes are durable Markdown files, while whiteboard editing needs an interactive canvas with structured shape data. tldraw provides a mature React whiteboard runtime and exposes snapshot APIs that can persist the document without using browser-local `persistenceKey` storage.
+
+The storage decision needs to preserve Tolaria's filesystem source-of-truth rule: deleting local caches must not lose a board, raw mode must expose the canonical source, and Git should track the board together with the surrounding note.
+
+## Decision
+
+**Tolaria will support whiteboards as Markdown-durable fenced `tldraw` blocks backed by tldraw document snapshots.**
+
+The implementation:
+
+- Converts fenced `tldraw` blocks into temporary placeholders before BlockNote parses Markdown.
+- Replaces those placeholders with `tldrawBlock` schema blocks that store a stable board id and tldraw document snapshot JSON.
+- Renders each block with the `tldraw` package inside the rich editor.
+- Debounces tldraw document changes into BlockNote block props so Tolaria's normal autosave writes the snapshot into the `.md` file.
+- Serializes `tldrawBlock` nodes back to fenced Markdown before save, raw-mode entry, and editor-position snapshots.
+- Adds a `/whiteboard` slash command that inserts the same block format.
+
+Session state such as camera position, selected shapes, and selected tools is not persisted into the note. Preview images are intentionally omitted from the initial design; they may be introduced later as derived cache artifacts for note lists, search results, or graph cards.
+
+## Options considered
+
+- **Markdown fenced block with tldraw document snapshot** (chosen): keeps the board in the note file, matches Tolaria's Mermaid/math round-trip model, and works for both full whiteboard notes and embedded boards inside larger notes.
+- **tldraw `persistenceKey` / IndexedDB**: simplest app integration, but violates the vault-as-source-of-truth rule and would lose boards when browser storage is cleared.
+- **Separate `.tldr` files embedded from Markdown**: keeps JSON out of prose notes, but fragments note ownership, makes embedded boards harder to move with their parent note, and complicates Git history for small board edits.
+- **Preview-image-first storage**: useful for thumbnails, but not editable source. It would make the PNG an attractive but stale source of truth.
+
+## Consequences
+
+- `src/utils/tldrawMarkdown.ts` is the canonical parser/serializer bridge for whiteboard blocks.
+- `src/components/TldrawWhiteboard.tsx` owns the tldraw runtime integration and only persists document snapshots.
+- Raw mode remains a direct source editor for the fenced JSON.
+- Embedded whiteboards and future full-note whiteboard templates share the same storage format.
+- Asset support is deferred; when added, asset bytes should live in vault-relative attachment paths referenced from the tldraw asset records.

+
+## Context
+
+Tolaria uses BlockNote for rich Markdown editing, Tauri for native desktop file drops, and custom editor drop handlers for images and wikilinks. BlockNote's default block drag path depends on HTML5 drag events and `DataTransfer`. On macOS inside the Tauri webview, that makes block reordering fragile because the same browser-level drag system also carries native file/image drops into the editor.
+
+Regressions tended to oscillate: fixes that restored block dragging could break image drops, and fixes that protected native drops could make block reordering fail or lose visual feedback. The drag handle also needs editor-specific affordances: a moving block preview, an insertion separator, stale-block protection, and typography-aware positioning for the side-menu controls.
+
+## Decision
+
+**Tolaria owns editor block reordering as a pointer gesture that directly moves BlockNote blocks, and leaves HTML5/native drag data paths for file, image, and external drops.** The drag side menu is responsible for resolving live BlockNote blocks, computing pointer hit targets, rendering drag affordances, and aligning the hover controls to the rendered text range of the hovered block.
+
+## Options considered
+
+- **Pointer-owned block reordering** (chosen): separates internal block moves from native drop payloads, works without `DataTransfer`, gives Tolaria deterministic visual affordances, and can be tested with Playwright pointer/mouse actions. Cons: Tolaria now owns a small amount of hit-testing, block-move, and affordance code around BlockNote.
+- **Continue using BlockNote's HTML5 drag handler**: keeps less local code, but ties internal block moves to the same unstable drag channel used by native file drops in Tauri.
+- **Patch native file drops around BlockNote drag events**: might repair individual regressions, but preserves the root coupling between editor-internal reordering and external drag payload handling.
+- **Disable block dragging on macOS/Tauri**: avoids the conflict, but removes an important editing workflow.
+
+## Consequences
+
+- Internal block reordering must not depend on `DataTransfer` or `draggable=true`.
+- File/image/wikilink drop behavior remains owned by the existing editor drop abstractions and native Tauri file-drop bridge.
+- Block reordering tests should use pointer or mouse movement in Playwright, and should assert the moving preview and insertion separator while the drag is in progress.
+- The side menu should align to measured rendered content rather than heading-specific pixel offsets, so future theme font-size and line-height changes do not need drag-control retuning.
+- Changes to BlockNote DOM structure around `.bn-block-content`, `.bn-inline-content`, `.bn-side-menu`, or block container IDs require rechecking the pointer hit-testing and side-menu alignment tests.

+## Context
+
+Tolaria's AI panel originally targeted desktop coding-agent CLIs only. That works well for tool-capable vault editing, but it excludes users who run local model servers, users who prefer OpenAI or Anthropic APIs, and future mobile builds where desktop subprocesses cannot run.
+
+## Decision
+
+**Tolaria models AI selection as an AI target.** Targets can be desktop coding agents or direct model endpoints. Coding agents keep the existing Safe / Power User permission modes and tool access. Direct model targets run in Chat mode: they receive note context and conversation history, but they do not get vault-write tools or shell access.
+
+Direct model provider metadata is stored in app settings. Provider API secrets are not stored in settings; hosted providers can either save a key in Tolaria's local app-data secrets file or read a key from a named environment variable. The local secrets file is outside the vault, outside project worktrees, and written with owner-only file permissions on Unix platforms. Local providers such as Ollama and LM Studio can run without a key.
+
+## Options Considered
+
+- **AI target abstraction** (chosen): supports agents, local models, hosted APIs, and mobile-compatible model runtimes without pretending all AI backends have the same capabilities.
+- **Treat custom providers as OpenCode configuration only**: lower implementation cost on desktop, but does not help mobile and keeps API users dependent on a coding-agent install.
+- **Direct API runtime with write tools immediately**: powerful, but would require Tolaria-owned tool loops, confirmations, retries, and safety semantics before the basic chat value is proven.
+
+## Consequences
+
+- Settings owns durable provider setup and default target selection.
+- The status bar becomes a quick target switcher across agents and configured model targets.
+- The AI panel explains capability differences: agents show Safe / Power User; direct model targets show Chat mode.
+- Future work can migrate local secrets to OS keychain storage and add read/write tool loops without changing the top-level target model.

+Tolaria renders generated SVG/HTML from trusted libraries such as Mermaid and KaTeX, and it allows users to opt into regex matching in filters and editor find/replace. Codacy SRM flagged the raw markup insertion and direct regex construction as Critical XSS/DoS risks.
+
+## Decision
+
+Add direct runtime dependencies on `dompurify` and `safe-regex2`.
+
+Rendered Mermaid SVG and KaTeX HTML must be sanitized before insertion and mounted through DOM nodes rather than React `dangerouslySetInnerHTML`. User-provided regex sources must be length-bounded and checked with `safe-regex2` before compilation.
+
+SCA-reported vulnerable transitive dependencies are pinned through package-manager overrides so Codacy resolves patched floors until upstream dependencies adopt them naturally. This includes `protobufjs`, the MCP SDK web-server stack, and Vite's parser/build transitive stack. Rust lockfile-only updates keep OpenSSL, rustls-webpki, and tar on patched versions without changing public Tauri APIs.
+
+## Consequences
+
+Markup rendering now has an explicit sanitizer boundary that is shared by Mermaid and math rendering. User regex features remain available, but unsafe or overly large expressions fail validation instead of running in the UI thread.
+
+The overrides should be removed once the dependency graph no longer pulls the vulnerable versions.
