Root cause: `new Date().toISOString().slice(0, 10)` returns UTC date,
causing date-based features to be off by up to ±1 day for non-UTC users.
Check-in / assistant workspace:
- Add `getLocalDateString()` utility, replace all UTC date comparisons
- Schema v2→v3 migration: normalize lastCheckInDate only when it matches
UTC today (ambiguous window); leave past dates untouched so check-in
triggers correctly after upgrade
- Runtime compat in `needsDailyCheckIn`: accept UTC today as fallback
for edge cases the migration cannot catch
- `needsDailyCheckIn(state, now?)` accepts optional time for testability
Usage stats:
- Replace single-offset SQL bucketing (`DATE(datetime(..., '+N minutes'))`)
with JS-side per-row aggregation using `getLocalDateString(new Date(utc))`
- Date methods account for historical DST offset at each message's timestamp
- `getTokenUsageStats(days, now?)` accepts optional time to pin window start
- Window boundary via `localDayStartAsUTC()` is already DST-aware
Tests (new file: timezone-boundaries.test.ts, 22 tests):
- getLocalDateString at UTC+9/UTC-5/UTC boundaries with fixed timestamps
- needsDailyCheckIn: compat suppression, clearly-past trigger, local match
- v2→v3 migration: targeted normalization, past-date preservation, null safe
- localDayStartAsUTC: UTC+8/UTC-5 midnight boundaries
- Usage stats bucketing: UTC+9 cross-day, summary window, DST spring-forward
- All usage stats tests use pinned `now` — no time-bomb from fixed test data

- ChatView: consume unconsumed stream snapshots on mount so output
appears after idle without needing a conversation switch
- PermissionPrompt: extract permission UI from StreamingMessage into a
fixed-position component at the bottom of ChatView, preventing
permission popups from scrolling off-screen during long responses
- StreamingMessage/MessageList: remove ~409 lines of permission UI code
now handled by PermissionPrompt
- AssistantWorkspaceSection: fix macOS Electron file selector by using
the correct IPC API (window.electronAPI.dialog.openFolder)
- AppShell: increase title bar drag region from h-5 to h-10 (#152)
- ChatView: add key={sessionId} on MessageInput to reset input state
when switching conversations (#176)
- UpdateDialog: add remark-gfm plugin and table component mappings for
proper GFM markdown rendering in release notes (#117)
- RightPanel: add border and top margin to collapsed panel toggle for
visibility (#116)

Assistant Workspace V2:
- Markdown indexing engine (incremental manifest + chunks JSONL)
- Keyword retrieval with CJK bigram support and hotset boosting
- Directory taxonomy inference and evolution suggestions
- Workspace config management (.assistant/config.json)
- Organize API: capture, classify, move, archive, suggest-evolution
Workspace switching:
- Inspect API (GET /api/workspace/inspect) for pre-switch validation
- Two-phase switching with confirmation dialogs (5 workspace statuses)
- Atomic save: init/reset runs before setSetting(), rollback on failure
- Auto-navigate to new/reused session after switch
- Mismatch banner in ChatView (only for former assistant sessions)
- Debounced path validation with visual indicators
Security hardening:
- Completion fence (onboarding-complete/checkin-complete) only processes
when session.workingDirectory === assistant_workspace_path (frontend)
AND session.working_directory === workspacePath (backend double-check)
- assertContained() in workspace-organizer: rejects absolute paths, ~/,
../ traversal, and symlink escapes for captureNote/moveFile
- organize API validates all path params at entry (validateRelativePath)
- captureDefault sanitized to relative path on onboarding write
- R_OK + W_OK validation on GET settings, session creation, and PUT
Bug fixes:
- hookTriggeredSessionId now read before auto-trigger; allows retry if
session has no messages (previous trigger failed silently)
- workspace-switched event listener matches oldPath (not just != newPath)
so normal project chats never show the mismatch banner
- Daily check-in card hidden when onboarding not complete
- Refresh docs now calls generateRootDocs() + generateDirectoryDocs()
- Banner "Open" button reuses latest session (checkin mode) instead of
always creating new onboarding session

Add "Assistant Workspace" feature that lets users designate a directory
(e.g. Obsidian vault) containing 4 Markdown files (soul.md, user.md,
memory.md, claude.md) to define AI personality, user profile, long-term
memory, and execution rules. These files are automatically injected into
the system prompt for assistant project sessions.
Core library (src/lib/assistant-workspace.ts):
- Workspace validation, initialization with template files
- File loading with 8000-char truncation, XML prompt assembly (40k limit)
- State management via .assistant/state.json
- Directory docs generation (README.ai.md + PATH.ai.md)
- Case-insensitive file name fallback (soul.md → SOUL.md)
System prompt injection (src/app/api/chat/route.ts):
- Scoped to sessions where working_directory === workspace path
- Workspace prompt prepended before session-level system prompt
- Onboarding/check-in instructions injected as <assistant-project-task>
- autoTrigger flag skips user message save and title update
Chat-based onboarding (10 questions) & daily check-in (3 questions):
- AI conducts conversation, outputs structured completion code blocks
- Frontend detects onboarding-complete/checkin-complete blocks
- Backend calls Claude API to generate file content from answers
- Fallback to raw answers if API call fails
Auto-trigger pipeline:
- Mount trigger (500ms delay) + focus fallback in MessageInput
- assistantTriggerFiredRef prevents duplicate triggers per mount
- hookTriggeredSessionId in state.json prevents cross-reload duplicates
- Daily check-in only triggers in the most recent workspace session
- hookTriggeredSessionId cleared via __clear__ sentinel after completion
API endpoints:
- GET/PUT /api/settings/workspace — path CRUD + file status
- POST /api/workspace/session — create (onboarding) or reuse (check-in)
- POST /api/workspace/onboarding — AI-generate soul.md + user.md
- POST /api/workspace/checkin — AI-update memory.md + user.md
- POST /api/workspace/hook-triggered — set/clear trigger guard
- GET /api/workspace/latest-session — latest session lookup
- POST /api/workspace/docs — refresh directory documentation
UI:
- Settings "Assistant" tab with workspace path, file status, controls
- Violet badge on workspace project group in ChatListPanel
- useAssistantWorkspace hook for state queries
Also includes:
- 102 passing tests (16 new regression tests for workspace logic)
- i18n keys for en.ts and zh.ts
- Handover documentation and execution plan
