Fixes #23727.
When the T3 home is reached through a symlink (~/.t3 linked to another disk, or a T3CODE_HOME that points at a link), the welcome wizard offers every projectless chat's scratch/<id> folder as a project to import. Claude Code and Codex record the resolved cwd. The scanner checks the candidate again with links resolved, but compares it against baseDir and worktreesDir in their unresolved spelling, so the prefix check never matches.
AgentSessionScanner resolves the base dir and worktrees dir through symlinks once, at construction, and excludes a candidate that falls under either spelling. A missing directory falls back to its resolved path, as before. The import path (recentThreads) uses the same exclusion, so it benefits as well.
This is a small, focused fix for an obvious bug, reported in #23727. The scanner already intends to exclude these folders under resolved links (the "check again with links resolved" comment, and the existing test excludes sandboxes reached through a symlink into the worktrees dir). This makes that check compare like with like and changes no other behavior.
#18198 also edits this exclusion, for linked worktrees on the import path. It does not resolve baseDir or touch the scan path, so the two changes are independent. Whichever lands second has a small rebase.
excludes T3 Code's own folders when its home is reached through a symlink to AgentSessionScanner.test.ts. The config base dir is a symlink, and a Claude transcript records a scratch folder under the real base dir. It creates the link itself, so it fails on main on Linux as well as macOS (expected [ { …(7) } ] to deeply equal [], the scratch folder offered as a candidate) and passes with the fix.excludes sandboxes reached through a symlink into the worktrees dir failed on macOS on main, because /var/folders resolves to /private/var/folders. It passes now.vp test run src/project/AgentSessionScanner.test.ts src/project/AgentSessionImporter.test.ts: 57 passed.vp run check:changed: format, lint, knip, graphql, typecheck, and tests pass.Not checked: a real install with a symlinked ~/.t3 in the desktop app. The new test covers the same scanner path.

Macroscope's review found this PR approvable — This is a small, focused server bug fix that extends an existing session-import exclusion check to both symlinked and resolved paths. It preserves normal-path behavior, adds a targeted regression test, and introduces no schema, default, infrastructure, security, or static-analysis changes.

The scanner now checks project candidates against both configured T3 directory paths and their resolved real paths. A test verifies that a scratch directory beneath the real path of a symlinked T3 home is excluded.

Explanation
The title names the change: session import in the server no longer offers T3 Code's own folders when the T3 home is reached through a symlink. The scanner change resolves baseDir and worktreesDir through symlinks and excludes candidates under either spelling, which matches the title. The title follows the conventional commit form and is 79 characters, within a typical length limit.
Explanation
The description follows the template sections (Problem, Change, Scope, Verification) and fills each one. The Problem section states the bug, the reproduction condition, and the expected behavior. The Change section explains the fix at the scanner level and notes the recentThreads import path. Scope links issue #23727, explains why no separate issue is needed beyond it, and notes the related PR #18198. Verification lists the added test, the existing test that now passes on macOS, the vp test and check commands with results, and states what was not checked (a real desktop install). The template's required CONTRIBUTING.md reminder is an HTML comment and does not need content. The agent-model line is absent; the template asks for it only if an agent was used, and the description does not say whether one was used.
Explanation
Issue #23727 requires that T3 Code's own folders (projectless chat sandboxes under scratch/, managed worktrees, and anything under the T3 home) are not offered for import when the home is reached through a symlink. The whole-PR diff against the merge base shows AgentSessionScanner.ts now resolves serverConfig.baseDir and serverConfig.worktreesDir with fileSystem.realPath in make. It keeps both the configured spelling and the resolved spelling, falling back to the configured spelling when realPath fails. isExcludedProjectPath then applies the base-dir prefix check and the isT3ManagedWorktree check against each spelling. The import path recentThreads uses the same isExcludedProjectPath check. The added test excludes T3 Code's own folders when its home is reached through a symlink creates a symlinked config base dir and a Claude transcript cwd under the real base dir, and expects no candidates. This covers the coding requirement. The real desktop-app install was not checked, as the PR states. That gap does not block the scanner-level requirement. Test execution results were taken from the PR description and were not re-run.
Explanation
The whole-PR diff against the merge base changes only apps/server/src/project/AgentSessionScanner.ts and apps/server/src/project/AgentSessionScanner.test.ts. The source change adds real-path resolution for the base and worktrees directories and applies the existing exclusion to both spellings. This implements issue #23727. The test change adds a symlink-gated scanner test for the same bug. No unrelated behavior or files appear in the diff. The change in PR #18198 is not present in this diff and was not assessed.

Thanks for this. #35266 makes the same change and is the one being kept.
The same fix is covered by #35266: it checks both configured and resolved spellings of the T3 home and worktrees directories, including scratch folders beneath the home.
Your scratch-folder regression directly captures the reported symptom and would be useful to carry into the retained change.
Closing as a duplicate.
