 - Agent dispatcher (`src/lib/agent-dispatcher.ts`) is a singleton that routes sidecar events to the agent store. Handles subagent routing (project-scoped sessions skip layout pane, render in TeamAgentsPanel; detached mode creates layout pane). Session persistence via registerSessionProject() + persistSessionForProject() (saves state + messages to SQLite on complete).
 - AgentQueryOptions supports `permission_mode` field (flows Rust -> sidecar -> SDK). Defaults to 'bypassPermissions', supports 'default' mode. allowDangerouslySkipPermissions is conditionally set. Also supports: `setting_sources` (defaults to ['user', 'project']), `system_prompt`, `model`, `claude_config_dir` (for multi-account), `additional_directories`.
 - Claude profiles: claude_list_profiles() reads ~/.config/switcher/profiles/ with profile.toml metadata. Profile set per-project in Settings (project.profile field), passed through ClaudeSession -> AgentPane `profile` prop -> resolved to config_dir for SDK. Profile name shown as info-only in ProjectHeader.

Three mount strategies: PERSISTED-EAGER (Model, Docs, Context — always mounted, display:flex/none), PERSISTED-LAZY (Files, SSH, Memory — mount on first activation via {#if everActivated} + display:flex/none). Tab type: `'model' | 'docs' | 'context' | 'files' | 'ssh' | 'memories'`. Model tab = ClaudeSession+TeamAgentsPanel. Docs tab = ProjectFiles (markdown viewer).

Files tab = FilesTab.svelte (VSCode-style directory tree + CodeMirror 6 editor with 15 language modes, dirty tracking, Ctrl+S save, save-on-blur setting, image display via convertFileSrc, 10MB gate; CodeEditor.svelte wrapper). SSH tab = SshTab.svelte (CRUD for SSH connections, launch spawns terminal tab in Model tab). Memory tab = MemoriesTab.svelte (pluggable via MemoryAdapter interface in memory-adapter.ts). Rust backend: list_directory_children + read_file_content + write_file_content (FileContent tagged union: Text/Binary/TooLarge). Frontend bridge: files-bridge.ts.

 - ProjectHeader shows CWD (ellipsized from START via `direction: rtl`) + profile name as info-only text on right side. AgentPane no longer has DIR/ACC toolbar — CWD and profile are props from parent.
 - Skill discovery: claude_list_skills() reads ~/.claude/skills/ (dirs with SKILL.md or .md files). claude_read_skill() reads content. AgentPane `/` prefix triggers autocomplete menu. Skill content injected as prompt via expandSkillPrompt().
 - claude-bridge.ts adapter wraps profile/skill Tauri commands (ClaudeProfile, ClaudeSkill interfaces).

 ### Added
+- **PDF viewer** in Files tab: `PdfViewer.svelte` using pdfjs-dist (v5.5.207). Canvas-based multi-page rendering, zoom controls (0.5x–3x, 25% steps), HiDPI-aware via devicePixelRatio. Reads PDF via `convertFileSrc()` — no new Rust commands needed
+- **CSV table view** in Files tab: `CsvTable.svelte` with RFC 4180 CSV parser (no external dependency). Auto-detects delimiter (comma, semicolon, tab). Sortable columns (numeric-aware), sticky header, row numbers, text truncation at 20rem
+- FilesTab routing update: Binary+pdf → PdfViewer, Text+csv → CsvTable. Updated file icons (📕 PDF, 📊 CSV)
 - **S-1 Phase 2: Filesystem write detection** — inotify-based real-time file change detection via `ProjectFsWatcher` (fs_watcher.rs). Watches project CWDs recursively, filters .git/node_modules/target, debounces 100ms per-file (fs_watcher.rs, lib.rs)
 - External write conflict detection: timing heuristic (2s grace window) distinguishes agent writes from external edits. `EXTERNAL_SESSION_ID` sentinel, `recordExternalWrite()`, `getExternalConflictCount()`, `FileConflict.isExternal` flag (conflicts.svelte.ts)
 - Separate external write badge (orange ⚡) and agent conflict badge (red ⚠) in ProjectHeader (ProjectHeader.svelte)

 ### v2/v3 Remaining
 - [ ] **Register Memora adapter** -- MemoryAdapter interface exists but no concrete adapter registered at app init. Need to create a MemoraAdapter that bridges to Memora MCP/CLI and register it on startup.
-- [ ] **Files tab PDF viewer** -- FilesTab marks PDFs as Binary. Add pdfjs-dist Canvas 2D rendering for inline PDF viewing.
-- [ ] **Files tab CSV table view** -- CSV files render as plain text. Add structured table rendering with column headers.
 - [ ] **E2E testing — expand coverage** -- 48 tests passing across 8 describe blocks (WebdriverIO v9.24 + tauri-driver, single spec file, ~23s). Add tests for agent sessions, terminal interaction.
 - [ ] **Multi-machine real-world testing** -- Test bterminal-relay with 2 machines.
 - [ ] **Multi-machine TLS/certificate pinning** -- TLS support for bterminal-relay + certificate pinning in RemoteManager.
