# Project State

## Project Reference

See: .planning/PROJECT.md (updated 2026-03-30)

**Core value:** Fresh onboard asks for ONE thing (root directory), auto-creates PM + Engineer, drops you in dashboard — no corporate language anywhere.
**Current focus:** Phase 25 — file-system

## Current Position

Phase: 25 (file-system) — EXECUTING
Plan: 4 of 9
Status: Ready to execute
Last activity: 2026-04-02

Progress: [██████████] 100%

## Accumulated Context

### Decisions

Decisions are logged in PROJECT.md Key Decisions table.
Recent decisions affecting current work:

- Roadmap: Company → Workspace (not Project) to avoid collision with existing Project entity
- Roadmap: Display-only renames — all code identifiers, DB schema, routes, env vars unchanged
- Roadmap: Branding package (`packages/branding/`) as single string mutation surface
- Roadmap: Vite alias redirects OnboardingWizard import to Nexus-owned replacement (Phase 4)
- Roadmap: `~/.nexus` pointer file with read-both-paths fallback for migration safety (Phase 2)
- [Phase 01-foundation]: Keep @paperclipai/branding package name for upstream sync compatibility
- [Phase 01-foundation]: Use as const for VOCAB to enable TypeScript literal type inference on all values
- [Phase 01-foundation]: Hook source tracked in scripts/nexus-commit-msg-hook.sh for post-clone reinstallation
- [Phase 01-foundation]: rerere.autoupdate=true so resolved conflicts are auto-staged during future rebases
- [Phase 21-chat-foundation]: Used object-syntax (table) => ({}) for Drizzle index callbacks to match existing codebase convention in documents.ts, agents.ts
- [Phase 21-chat-foundation]: Use it.todo() (not it.skip()) for Wave 0 test scaffolding — vitest marks todos semantically, no false positives
- [Phase 21-chat-foundation]: Minimal imports in test stubs — no service mocks until Plans 01-05 wire up implementations
- [Phase 21-02]: Use ExtraProps from react-markdown for ChatCodeBlock type signature to satisfy ComponentType constraint
- [Phase 21-02]: Add hljs CSS as plain rules (not @import) scoped to .dark, .theme-tokyo-night, :root selectors
- [Phase 21-chat-foundation]: ChatPanelProvider inside PanelProvider so ChatPanel can call setPanelVisible to close PropertiesPanel
- [Phase 21-chat-foundation]: Chat toggle button in desktop sidebar bottom controls with hidden md:inline-flex
- [Phase 21-03]: Pitfall 3 (updatedAt bump): addMessage always updates chatConversations.updatedAt after inserting — ensures conversation list sort order stays correct
- [Phase 21-03]: Pitfall 5 (auto-title idempotency): WHERE title IS NULL guard makes auto-title set safe to call multiple times
- [Phase 21-03]: Missing export fix: createConversationSchema/updateConversationSchema/createMessageSchema were in validators/chat.ts but not re-exported from shared/src/index.ts
- [Phase 21-chat-foundation]: Two-path handleSend in ChatPanel: direct chatApi for path 1 (no active conversation) avoids hook mutation needing a conversationId that does not exist yet
- [Phase 21-chat-foundation]: messages array in useChatMessages flattened from pages and reversed so display is chronological (API returns desc by createdAt)
- [Phase 21-chat-foundation]: Custom window event (nexus:focus-chat-search) used instead of forwardRef drilling to focus search input from Cmd+K
- [Phase 21-chat-foundation]: Cmd+K handler placed before input-guard early return in useKeyboardShortcuts so it fires globally even from input/textarea
- [Phase 22-agent-streaming]: Use fetch ReadableStream instead of EventSource for POST SSE streaming endpoint
- [Phase 22-agent-streaming]: streamEcho stub yields word-by-word with 50ms delay; Phase 23 replaces with real LLM adapter
- [Phase 22-agent-streaming]: Partial content on stop saved with [stopped] suffix via chatApi.savePartialMessage
- [Phase 22-agent-streaming]: isAnyStreaming prop (not isStreaming) distinguishes global streaming state for disabling edit/retry globally in ChatMessage
- [Phase 22-agent-streaming]: /search disabled with Coming soon; resolveAgentFromContent routes slash > @mention > active agent
- [Phase 22-agent-streaming]: [Phase 22-05]: virtualizer.measure() on streamingContent change handles dynamic height re-measurement for growing streaming message (Pitfall 3)
- [Phase 22-agent-streaming]: [Phase 22-05]: handleRetry truncates from user message (not assistant), removing assistant + all subsequent messages before re-streaming
- [Phase 23-brainstormer-flow]: Added journal entries for idx 47 (nebulous_klaw) and 48 (add_chat_messages_updated_at) retroactively to keep journal consistent with files on disk
- [Phase 23-brainstormer-flow]: Used @/lib/router Link abstraction (not react-router-dom) for ChatTaskCreatedBadge and ChatStatusUpdateBadge — consistent with all other link components in the codebase
- [Phase 23-brainstormer-flow]: ChatSpecCardInner extracted as inner component to avoid conditional hook calls after JSON.parse error path in ChatSpecCard
- [Phase 23-brainstormer-flow]: issueService imported directly in chatRoutes(db) — option (a) from plan, simplest approach matching heartbeat.ts pattern
- [Phase 23-brainstormer-flow]: Used activeConversationId === null as proxy for new conversation in brainstormer auto-select
- [Phase 23-brainstormer-flow]: Used useToast()/pushToast() for error toast in ChatPanel handleHandoff (custom ToastContext, not sonner)
- [Phase 24-search-history-branching]: Used AnyPgColumn type annotation for parentConversationId self-referential FK — matches existing pattern in issues.ts, goals.ts, execution_workspaces.ts
- [Phase 24-search-history-branching]: content_search tsvector column omitted from Drizzle schema — Postgres-generated stored column queried via raw sql`` only
- [Phase 24-search-history-branching]: searchMessages returns empty items early when query.trim() is empty — avoids PostgreSQL error on blank tsquery
- [Phase 24-search-history-branching]: exportConversation uses this.getConversation() to reuse notFound guard without duplicating query logic
- [Phase 24-search-history-branching]: Used HighlightedText React component instead of innerHTML for term highlighting — eliminates XSS surface
- [Phase 24-search-history-branching]: exportConversation returns URL string (not fetch call) since server sends file download via browser navigation
- [Phase 24-search-history-branching]: shouldFilter=false pattern on Command for server-side FTS — all future search dialogs should follow this
- [Phase 24-search-history-branching]: Custom event nexus:open-chat-search routes search trigger through CommandPalette without Cmd+K conflict
- [Phase 24-search-history-branching]: Branch-on-edit checks editedIdx < messages.length - 1 before calling branchConversation
- [Phase 24-search-history-branching]: bookmarkedMessageIds as Set<string> for O(1) lookup rebuilt from useChatBookmarks per-conversation data
- [Phase 25-file-system]: Used object-syntax (table) => ({}) for Drizzle index callbacks in chat_files and chat_file_references — matches existing codebase pattern
- [Phase 25-file-system]: chatFiles uses nullable FKs (SET NULL) for conversationId/messageId — file may exist before a conversation or message is created
- [Phase 25-file-system]: chatFileReferences uses CASCADE deletes for fileId and conversationId — reference has no meaning without both anchors
- [Phase 25-file-system]: Used XHR instead of fetch for chatApi.uploadFile to enable upload progress events (fetch lacks upload.onprogress)
- [Phase 25-file-system]: ChatInput onFilesPicked/pendingFiles/onRemoveFile props are all optional for backward compatibility
- [Phase 25-file-system]: Content-Length uses object.contentLength from storage ?? chatFile.sizeBytes to prevent stream ECONNRESET
- [Phase 25-file-system]: createFileReferenceSchema.safeParse() receives fileId injected from URL param for UUID format validation
- [Phase 25-file-system]: ChatFilePreview shows inline image with max-h-[300px] + ChatFileCard below; non-image types use ChatFileCard only
- [Phase 25-file-system]: listMessages fetches chatFiles with inArray(messageId) as second query, merged in-memory
- [Phase 25-file-system]: completedFileIds captured before clearCompleted in handleSend to avoid race condition
- [Phase 25-file-system]: Use functional setState for transcription append in VoiceRecordButton — avoids stale closure vs native DOM event approach
- [Phase 25-file-system]: enableVoiceInput defaults to false for backward-compat; ChatPanel passes true unconditionally — server returns 503 gracefully if whisper absent
- [Phase 25-file-system]: execFileAsync over exec for whisper CLI invocation — no shell injection risk with system-generated tmpPath
- [Phase 25-file-system]: Used DOMParser + replaceChildren to safely render hljs output — avoids raw HTML injection pattern while preserving same visual output as rehype-highlight
- [Phase 25-file-system]: highlight.js added as explicit ui/package.json dependency (was transitive via rehype-highlight only)
- [Phase 25-file-system]: Used execFile (not exec) for git commands in gitFileService — array-based args prevent shell injection
- [Phase 25-file-system]: Git commit is fire-and-forget after upload — response not blocked by git operation
- [Phase 25-file-system]: History route placed before /content route to avoid Express path ambiguity on /files/:fileId/*

### Pending Todos

None yet.

### Blockers/Concerns

- Phase 4: `POST /api/companies` required fields not fully documented — read `server/src/routes/companies.ts` before implementing new wizard
- Phase 3: Exact count of test files asserting on old display strings unknown — grep audit needed as first step
