Failed to move managed checkout into place at "${cwd}": ${re

Error message

Failed to move managed checkout into place at "${cwd}": ${reason}

What it means

Materialization race/failure in heartbeat workspace materialization: the staged clone succeeded but fs.rename from the temp dir into the final cwd failed for the stated reason. The temp clone is cleaned up; if the target appeared concurrently the caller may adopt that checkout, otherwise the managed checkout cannot be placed and the error propagates.
