Pass appendTruncationMarker: true to the ls-remote call.

Without this option, output over 16 MiB fails the command instead of marking it truncated. The result.stdoutTruncated ? null check never triggers, and the failure is cached as an empty tag set. The worktree is still kept, but the report says the commits are not on a remote-tracking ref instead of reporting that the inspection limit was exceeded. Setting the option makes the truncation branch reachable and returns exceeded for oversized output.

The other stdoutTruncated checks in this file have the same gap, because no call in the file sets the option. Their overflow surfaces as a command error instead of a truncation result.

Suggested fix 

             maxOutputBytes: 16 * 1024 * 1024,
+            appendTruncationMarker: true,

Review comment at @apps/server/src/storageCleanup.ts around lines 719 - 735:
Enable truncation-marker output for the git command in StorageCleanup.remoteTags
so oversized output reaches the existing stdoutTruncated check instead of being
treated as an empty tag set. Apply the same option to other git calls in this
file whose results are checked for stdoutTruncated.

review. Visit https://docs.coderabbit.ai/cli?utm_source=ghpr

Move remote tag lookups outside the workspace lease.

If a submodule has unpushed history and local tags, a slow remote can delay provider startup for the same worktree by up to 20 seconds per uncached remote. Recheck the local submodule state and remote configuration under the lease before removal.
