ApprovabilityVerdict: Not approved Macroscope's review found this PR not approvable — This is a cross-cutting production feature introducing multi-repository discovery, checkpoint fan-out, isolated worktree orchestration, agent-instruction changes, and new Git UI workflows, rather than a small isolated change. Unresolved medium/high findings additionally identify risks involving cleanup, branch consistency, path containment, prompt injection, and diff correctness. Not approved because:

Suggested reviewers: Merge Risk: 🔵 Low · up to Repository changes may leave Claude with outdated guidance, and a failed worktree launch may not retry successfully with the same branch. Project-controlled repository names also remain in agent prompt text. These are bounded risks, but the worktree retry and prompt handling warrant owner attention.

🩺 Stability & Availability | 🟡 Minor | ⚡ Quick winHandle explicit branches when retrying partial worktree creation.
An ordinary launch can provide
workspaceStrategy.branch.ThreadLaunchServicepasses that branch toWorkspaceWorktrees.create. If a later repository fails, the retry passes the original worktree strategy because the failed attempt did not record a worktree path. The retry therefore uses the same branch name. The retained branch ref can make the nextgit worktree add -bfail again.Keep the caller-provided branch on a successful launch. On rollback, remove only refs created by the failed attempt, or assign a fresh temporary branch for the retry. Do not remove a pre-existing caller-provided branch.

A project folder that is not a Git repository can still hold several: a wrapper with one checkout per repository. WorkspaceRepositories lists them: the folders a .code-workspace file in that folder names, or every immediate child with a .git entry when there is no such file. Folders outside the workspace are never included, and discovery reads only the filesystem so hot paths can call it freely. vcs.listRepositories exposes the same list to clients, keyed by cwd like the other VCS RPCs. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
…olds In a multi-repo workspace the agent's working directory is not a Git repository, so Git commands run there fail. The runtime policy now carries the workspace's repositories, and every adapter adds a short block to its runtime instructions naming them and asking the agent to run Git inside the repository it is changing. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
Checkpoints treated a workspace folder that is not itself a Git repository as missing, so multi-repo projects had no turn diffs and no rewind. CheckpointStore now fans each operation out to the folder's repositories under the same ref and reports diff paths relative to the folder, so turn diffs, changed-file summaries and restores work without changes to checkpoint scopes, events or projections. A restore first checks every repository holds the checkpoint, so a repository added mid-thread makes the restore unavailable instead of partial. isGitRepository becomes isCheckpointable to match. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
…er repository A worktree launch ran git in the project folder, which in a multi-repo workspace is not a repository, so isolated runs failed. The launch now creates a container folder that mirrors the project: one worktree per repository at the same relative path, all on the thread's branch, plus links to the project's other top-level entries so shared instructions and editor settings resolve as they do in the project. A .code-workspace file defines which folders belong to the workspace, so with one only its listed folders are linked, along with top-level files and dot-folders. The thread records the container as its worktree path, so the agent, file search, checkpoints and restore safety keep working on one folder. Each repository starts from its own default branch. The background branch rename and worktree removal (thread deletion, failed setup) cover every repository; removal keeps the container if it holds anything other than its worktrees and links. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
…ulti-repo workspace A multi-repo workspace folder is not a Git repository, so the thread hid its Git surfaces: no worktree runs, no diff panel, no source control. Once Git status reports the folder is not a repository, the web client asks for its repositories and: - offers New worktree without asking for a base branch, since each repository starts from its own default; - shows one source control section per repository in the thread panel, without letting any one repository rewrite the thread's branch; - opens the diff panel, where turn diffs cover every repository and Uncommitted and Changes compare the repository picked beside the scope. Ordinary checkouts never make the extra request. On the server, the turn-end refresh now re-reads the Git status (and branch pull request) of every repository the folder holds, so each section shows the run's changes as soon as it ends.

Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
- After a run in a multi-repo project folder, refresh each repository's pull request status for whatever branch it has checked out. - Accept workspace folders whose names start with `..`, such as `..api`. - Tell agents the repository paths and names are identifiers, not instructions. - Log which repositories were already restored when a later one fails. - Remember the diff panel's selected repository across reloads.
…ew repositories - A turn's baseline now captures only in the repositories that lack the ref. Before, one repository missing it (cloned in mid-thread, or after a partial capture) re-captured every repository and overwrote their good checkpoints, so edits made between turns leaked into earlier turns' diffs and rewinds. - Switching the diff panel to another repository goes back to the automatic base, since a base branch picked in one repository may not exist in another.

What Changed
A project folder that isn't itself a Git repository but holds several repositories now works as a multi-repo workspace. If the folder has one
.code-workspacefile, the folders it lists are the repositories, named as the file names them. Otherwise they're the immediate child folders with a.gitentry. Folders outside the project are never included.workspace/WorkspaceRepositories.ts,vcs.listRepositories). Reads only the filesystem and persists nothing: no migrations, no new events or projection fields.checkpointing/CheckpointStore.ts).git/WorkspaceWorktrees.ts)..code-workspace, only its listed folders are linked, along with top-level files and dot-folders.worktreePathis the container, so the agent, file search, assets and restore safety still work on one folder.docs/user/source-control.md.Single-repo projects are unchanged. The client only asks for repositories once Git status says the folder isn't a repository.
Why
Discussion #7041 is the long-standing request. #11251 was closed with "If this is still an issue once V2 lands, please reopen (or open a fresh PR against the new code)", and this is that fresh PR against V2. This follows the #12089 triage: only repositories inside the project folder count, and sibling repositories are never captured, restored or scanned.
V2 gives each thread a single working folder, and that assumption runs through scopes, sessions and the runtime policy. Instead of threading lists of repositories and worktrees through events and projections, this treats the project folder, or the thread's container, as that single folder. Only the places that actually run Git loop over the repositories. That keeps the core graph untouched and needs no schema changes.
Not included:
.env,node_modulesand shared folders), so changes to them aren't isolated, checkpointed or rewound.UI Changes
Demo workspace: a folder with two repositories (
api,web) listed in a.code-workspacefile. Same project and same prompt before and after.Thread panel. Before, a folder holding two repositories only offers "Initialize Git". After, there's one Git actions section per repository.
After a turn that edits both repositories. Before, nothing is captured: no changed files and no diff. After, the turn lists changed files grouped by repository, here on a New worktree run with one worktree per repository.
Diff panel. Uncommitted and Changes get a repository picker.
