Phase 25: File System Verification Report (Final Re-verification)

Phase Goal: Users and agents can upload, generate, preview, and download files in chat, with all files tracked in libSQL, version-controlled by git, and accessible across devices Verified: 2026-04-01T00:00:00Z Status: human_needed (all automated checks pass) Re-verification: Yes — after merging worktree code for FILE-09/FILE-10

Re-verification Summary

This is the third verification pass for Phase 25. The previous verification (score 13/15) identified two gaps:

  1. server/src/services/git-file-service.ts did not exist on the deliverable branch (was in a separate worktree).
  2. GET /files/:fileId/history route was absent in server/src/routes/chat-files.ts.

Both gaps have been resolved. The merged code has been verified to be substantive and correctly wired.

No regressions detected — all 13 previously-verified truths remain intact.

All 16 requirement IDs satisfied. No orphaned requirements.

Anti-Patterns Found

None blocking. The git commit call at line 106 uses .catch(() => {}) (fire-and-forget), which is intentional — a git commit failure should not fail the upload. This is acceptable.

Human Verification Required

1. Drag-and-drop file upload

Test: Drag any file onto the chat input area Expected: Drop zone overlay with dashed border and "Drop files here" text; on release, file uploads with a progress chip Why human: Drag-and-drop visual feedback requires a running browser

2. Clipboard paste upload

Test: Copy a screenshot image, focus the chat textarea, paste (Ctrl+V or Cmd+V) Expected: Image upload begins immediately, progress chip appears above textarea Why human: Clipboard paste requires a running browser

3. File picker upload

Test: Click the Paperclip button in ChatInput, select any file from the native picker Expected: Native file picker opens; selecting a file starts the upload and shows a pending chip above the textarea Why human: Native file picker requires a running browser

4. Syntax-highlighted code preview

Test: Attach a .ts or .py file to a chat message and view the sent message Expected: ChatCodeFilePreview renders with syntax highlighting, copy button, language label, and download card below Why human: highlight.js rendering requires a running browser

5. Voice input transcription

Test: Click the microphone icon, speak a sentence, click the stop (square) button Expected: Loader2 spinner shows while transcribing; transcription text inserted into textarea Why human: MediaRecorder API and microphone permission require a running browser with audio hardware

6. File scope promote button

Test: In a project-linked conversation, view a ChatFileCard. Click the FolderUp button. Expected: File is promoted to project scope; FolderUp button disappears from the card Why human: Requires running app with real project context and DB state

7. Git commit created on file upload

Test: Upload a file via the chat interface. On the server, inspect the storage directory: git -C <storage_dir> log --oneline should show a new commit "Upload: " Expected: A commit with the upload message appears in the git log Why human: Requires running server with access to the file system storage directory

8. File history API returns git log entries

Test: After uploading a file, call GET /api/files/:fileId/history Expected: { "items": [{ "hash": "...", "date": "...", "message": "Upload: ...", "author": "Nexus File System" }] } Why human: Requires running server and a file that has been committed to git storage

Summary

All 15 observable truths are now VERIFIED. All 16 requirements are SATISFIED. No blocking anti-patterns.

The two gaps from the previous verification (FILE-09 git integration, FILE-10 history endpoint) have been resolved by merging the worktree code:

  • server/src/services/git-file-service.ts — 101 lines; substantive implementation using execFile("git", ...) with ensureRepo, commitFile, and getLog methods
  • server/src/routes/chat-files.ts — now imports gitFileService, instantiates gitSvc, calls gitSvc.commitFile non-blocking on upload (line 106), and serves GET /files/:fileId/history via gitSvc.getLog (lines 136-151)
  • packages/shared/src/types/chat.ts — ChatFileHistoryEntry interface (hash, date, message, author) exported from the shared package

No regressions detected in any previously-verified artifact.

The phase goal is achieved at the code level. Eight items require human browser/server verification for final confirmation of end-to-end behavior.
