Opening the same checkout through a symlink and its physical path can register two projects in one environment. On macOS, a parent link such as ~/Code -> /Volumes/Development/Code reproduces this: both registrations already have the same resolved repository identity root, but workspace ownership compares the unresolved path strings.

Resolve validated workspace roots with realPath, including roots just created under a symlinked parent. Project lookup and ownership checks also resolve older saved roots when the indexed exact-path lookup misses. This reuses legacy registrations and rejects duplicate creates or moves, while keeping separate folders distinct even when they represent the same repository. Existing duplicate records, thread histories, and settings are not merged or deleted.

This is a focused fix for an obvious filesystem-identity bug under the small-fix exception in CONTRIBUTING.md. The change stays in shared server path normalization and project ownership, covering client and MCP entry points without changing client contracts.

Verification on macOS arm64, Node 26.13.0:

• Filesystem reproduction: the two reported paths resolve to the same physical directory and have identical device/inode values; os.path.samefile returns true.
• The regression failed before the fix because a symlink path was persisted instead of the physical root. It now covers creation under a symlinked parent, legacy saved aliases, bootstrap reuse, duplicate-create and move rejection, lookup including deleted records, and distinct checkout folders.
• vp run check:changed: passed format, lint, both knip checks, GraphQL validation, typechecking of the three affected packages, and 26 tests across four files.
• vp test run apps/server/src/workspace/WorkspaceEntries.test.ts apps/server/src/workspace/WorkspaceFileSystem.test.ts apps/server/src/project/ProjectService.deletion.test.ts: 57 tests passed.

The installed application and live database were not modified. Existing duplicate records still require separate reconciliation; this PR prevents new aliases from being registered as additional checkouts.

Walkthrough

Workspace root normalization now returns filesystem-resolved paths. Project lookups match stored symlink aliases to the same project. CLI project targeting also resolves aliases. Tests cover alias lookup, bootstrap reuse, duplicate conflicts, and distinct folders.

Changes: Canonical workspace roots

Layer / File(s)	Summary
Resolve workspace roots to real paths apps/server/src/workspace/WorkspacePaths.ts, apps/server/src/workspace/WorkspacePaths.test.ts	normalizeWorkspaceRoot returns the real path after validating the root. Real-path resolution failures use the resolve-real-path phase. The test expects the resolved path.
Match projects by canonical workspace root apps/server/src/project/ProjectService.ts, apps/server/src/project/ProjectService.test.ts, apps/server/src/cli/project.ts, apps/server/src/cli/project.test.ts	findByWorkspaceRoot checks exact roots and then normalized stored roots. Project-command ownership lookup and getByWorkspaceRoot use this helper. CLI project targeting checks expanded, normalized, and canonical active roots. Tests cover symlink aliases, bootstrap reuse, conflicts, removal, and distinct folders.

Full details: Title check

Explanation

The title "fix(server): deduplicate symlinked project checkouts" matches the main change. The changeset resolves workspace roots to real paths and makes project lookup and ownership checks resolve stored aliases, so symlinked checkouts map to one project. The title is a conventional commit, short, and specific.

Full details: Description check

Explanation

The description covers the problem (duplicate registrations via symlink and physical path), the change (realPath resolution, legacy alias lookup, duplicate create and move rejection), scope (a small bug fix, with a reference to the CONTRIBUTING.md small-fix exception and no linked issue), and verification (macOS reproduction, targeted tests, and check results). It also notes what was not changed. The template asks for a conventional commit title and a model/harness line when an agent was used; the author did not include the agent line, and the Scope section does not link an issue. These gaps are minor.

Note

Written by claude-opus-5-5 on behalf of Maria

Takeover fixup: Test Server 5 failed because src/cli/project.test.ts still expected a symlink alias to register as a second project. This PR removes that behavior. The case now expects project add <alias> to be rejected and project remove <alias>/. to remove the original project. No source changes.

Canonicalize the cwd before the project settings lookup in projectSettingsFor.

projectSettingsFor matches input.cwd exactly against stored workspace_root values. This PR stores newly registered roots as physical paths. A vcsCreateWorktree request that sends the symlink alias as cwd, without projectId or threadId, can no longer match its row. The lookup then returns no project ID. Worktree creation uses the global worktreeSubmodules value and ignores the project override. Before this PR, the stored alias matched the same input, so the override applied.

The RPC passes no explicit submodules option, so this settings fallback is the only source of the value.

Normalize input.cwd to the same physical identity used when roots are stored, before calling findActiveByWorkspaceRoot. Legacy alias rows still need a fallback. ProjectService.findByWorkspaceRoot already provides one, so routing this lookup through equivalent logic keeps legacy rows matching.

apps/server/src/workspace/WorkspacePaths.ts:173-183
Minor · Functional Correctness · Quick win

Add an alias-aware fallback to CLI project target lookup.

findActiveProjectTarget compares stored workspace roots only by exact equality. normalizeWorkspaceRootForProjectCommand now returns the resolved physical path for an existing directory. A project stored with an alias spelling therefore does not match its alias identifier. project remove <alias> fails with ProjectNotFoundError, and the project stays active. Removing by project ID still works.

When the exact comparison misses, normalize each active stored root and compare the result with normalizedWorkspaceRoot. The exact-ID lookup stays first. A stored root whose directory is missing fails normalization and does not match, so the missing-directory error path is unchanged.

Suggested fix

-  const resolved = exactWorkspaceMatch;
+  const resolved =
+    exactWorkspaceMatch ??
+    Option.getOrUndefined(
+      yield* Effect.findFirst(activeProjects, (project) =>
+        normalizeWorkspaceRootForProjectCommand(project.workspaceRoot).pipe(
+          Effect.map((root) => root === normalizedWorkspaceRoot),
+          Effect.orElseSucceed(() => false),
+        ),
+      ),
+    );

Move alias-aware project resolution into the project service.

This fallback duplicates the filesystem traversal and failure handling in ProjectService.findByWorkspaceRoot. Keep project identity rules in the owning service so the CLI and other consumers cannot diverge.

As per coding guidelines, “Filesystem, Git, process, or persistence work, folder naming, multi-step dispatch, retries, and rollback belong in the service.”

Note

Written by gpt-6.1-sol on behalf of Maria

Verified in a real dev environment

verified on linux in google chrome using the repository’s playwright dependency, one real vp run dev server at a time, and real codex gpt-6.1-sol turns. projects and threads were created through the web app; no replay provider, mocks, fixtures, or demo data.

• on github/main (cef95b6db9), adding /home/user/verify32212/alias/checkout and /home/user/verify32212/physical/checkout created two projects for the same directory. alias is a symlink to physical. a real codex turn wrote verification.txt.
• on this pr, a new project added through alias/fresh was saved as physical/fresh. adding its alias again was rejected. opening its saved physical path returned to the existing thread. a real codex turn wrote the file; after restarting the server, another turn read it and confirmed its contents survived.
• a separate clone added through alias/second remained a distinct project, saved as physical/second.
• the app also rejected the physical path of the legacy alias registration. to isolate that check, i explicitly removed the extra physical-path project from the copied reproduction data. the pr does not reconcile existing duplicate records.
• verification found two cli regressions: a lone legacy alias could not be renamed, and an exact saved alias could target the other project when both spellings were already registered. fixed in 6dfb3e6200 and bee7ea2de9. live cli rename and removal now select the intended project and preserve the other registration. these commands reached the running server, including its /api/projects/mutate endpoint.

short runtime transcript from isolated copies of the app-created data:

before: project rename /home/user/verify32212/alias/checkout ...
ProjectNotFoundError: No active project found

after: project rename /home/user/verify32212/alias/checkout ...
Renamed project 6899c86d-072d-467f-b3a6-61ba91360e16

with both legacy registrations, before the saved-path correction:
project rename /home/user/verify32212/alias/checkout/. alias-target-probe
Renamed project 63ca7977-6890-48b7-8288-eb63ae7fab36 (wrong project)

after the correction:
project rename /home/user/verify32212/alias/checkout/. alias-target-correct
Renamed project 6899c86d-072d-467f-b3a6-61ba91360e16
project remove /home/user/verify32212/alias/checkout/. --force
Removed project 6899c86d-072d-467f-b3a6-61ba91360e16
physical-path project 63ca7977-6890-48b7-8288-eb63ae7fab36 remained active

vp run check:changed 23bdb9ef1cc39ddb21a3e077f97f580d50b8fc22 passed through blacksmith: format, lint, both knip checks, graphql validation, typechecks for three packages, and 39 tests. all 13 cli tests also passed with a symlinked TMPDIR. the extended existing regression test failed on the preceding code before the saved-path fix. two independent code reviews approved bee7ea2de9e1c752cc7a8b18e76656804098c575.

main: two projects for one checkout.

pr: the same physical path is rejected when its legacy alias already owns the checkout.

real codex turn through the pr web client.

recording: alias rejection, reopening the existing thread through its physical path, and a separate clone remaining distinct. inspected the clip and verified uploaded playback and seeking.

Not verified

native macos/windows filesystem behavior, native mobile clients, the electron shell, other providers, and relay/tunnel connections were not exercised on this linux vm. the shared server behavior was exercised through the linux web client and codex. all seven reported github checks are green. github reports conflicts with current main; those remain untouched because this verification brief forbids merging and rebasing.
