feat(web): group onboarding project import by repository

[t3dotgg]

Onboarding listed every directory Claude Code or Codex had ever run in as one flat list of paths, with everything from the last 30 days preselected. On my machine that was 270 rows and 80 preselected. Most of them were Codex scratch folders, worktrees, and one-off questions. I wanted two or three projects and had no fast way to get there.

The scanner now reads each candidate's .git/config directly, so the client can group clones by origin and show the GitHub owner/name. Linked worktrees, Codex scratch directories under ~/Documents/Codex, ~/Downloads, and temp roots are no longer offered. Folders that are not git repositories collapse under "Other folders". The default selection requires a git repository with at least three threads. Select all and Select none sit above the list, and each row shows the source icons, thread count, and last activity.

On the same machine this drops the list to 162 rows and the default selection to 16.

Before	After

Mobile has no project import step, so there is no mobile change.

Created with Claude Fable 5.1 in Claude Code.

Note

Add Git identity and repo grouping to AgentSessionScanner scan logic

• Adds a nullable Git identity field to scan candidates so non-repository workspaces are represented with a null value
• Groups Codex rollouts by cwd across date directories and merges Claude and Codex candidates for imported projects
• Excludes Codex scratch directories and Downloads paths from scan results, keeping only ordinary workspaces eligible
• Skips linked git worktrees (gitdir pointer) while reporting normalized remote and GitHub repository metadata for real checkouts
• Behavioral Change: existing test expectations now require the new Git identity field on all candidate assertions; callers consuming scan candidates must handle the added field

Summary by CodeRabbit

• New Features

  • Onboarding now groups cloned projects by repository and shows repository details, thread counts, activity, and selection controls.
  • Git-backed projects display normalized repository information, including GitHub owner and repository names.
  • Project selection supports selecting all or none, with grouped and collapsible project lists.

• Bug Fixes

  • Linked worktrees and scratch or download folders are no longer offered as projects.

Approvability

Verdict: Not approved

Macroscope's review found this PR not approvable — This PR adds repository-aware onboarding behavior across the scanner, contract, and picker UI, while changing the default set of projects selected for import. It also leaves an unresolved concern for repositories whose remotes are supplied through Git include files, so the combined behavior and default-selection changes merit human review.

📝 Walkthrough

Walkthrough

The scanner reports Git identity, skips linked worktrees and excluded directories, and supplies repository-aware candidates. Onboarding groups candidates by repository, narrows default selections, and displays grouped project controls with updated documentation.

Changes

Repository-aware onboarding project import

Layer / File(s)	Summary
Git metadata contracts and parsing packages/contracts/src/agentSessions.ts, packages/shared/src/git.ts, packages/shared/src/git.test.ts	Adds nullable Git metadata to scan candidates and parses Git configuration and GitHub repository names.
Scanner filtering and Git identity apps/server/src/project/AgentSessionScanner.ts, apps/server/src/project/AgentSessionScanner.test.ts	Excludes temporary and scratch directories, skips linked worktrees, and reports normalized repository metadata. Tests cover excluded paths, repositories, worktrees, submodules, and nullable Git fields.
Candidate grouping and default selection apps/web/src/onboarding/projectImport.logic.ts, apps/web/src/onboarding/projectImport.logic.test.ts	Defaults selection to active Git candidates with at least three threads and groups clones by origin while separating local folders.
Grouped onboarding selection UI apps/web/src/components/onboarding/WelcomeWizard.tsx, docs/user/welcome-wizard.md	Adds grouped repository rows, tri-state selection, Select all/Select none controls, project metadata, and updated onboarding documentation.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🟡 Moderate · up to e4c43

Projects using mixed-case deprecated Git remote headers can be grouped under the wrong repository during onboarding, producing misleading repository labels and selections. This should be corrected before merge.

- Around line 873-874: Update the test setup around the scratch and downloads
path definitions to generate unique, test-owned child directories under
NodeOS.homedir(), rather than fixed shared paths. Ensure the finalizer
recursively removes only those generated paths, preventing deletion of
pre-existing user data and interference between concurrent runs.

In `@apps/server/src/project/AgentSessionScanner.ts`:
- Line 702: Update readGitIdentity and the scan path so a non-directory .git
entry is not automatically classified as Worktree. Parse the gitdir target,
distinguish linked worktrees using their worktree metadata, and for submodule
gitfiles read the pointed repository config before returning Repository so valid
submodule directories are retained.

In `@packages/shared/src/git.ts`:
- Line 156: Update the origin-section detection in parseOriginUrlFromGitConfig
so the remote section matching remains case-insensitive while the subsection
name is extracted and compared exactly to "origin". Remove the case-insensitive
matching that accepts "ORIGIN" or "Origin", preserving the existing handling of
valid origin URLs.
- Around line 160-163: Update parseOriginUrlFromGitConfig to parse
Git-compatible config values before returning them: strip comments from unquoted
values and decode quoted values, while preserving valid URL content. Ensure
AgentSessionScanner.readGitIdentity receives the cleaned value for
normalizeGitRemoteUrl, and add regression coverage for unquoted comments and
quoted URLs.
