Why my space won't load?
Problem: The org Space build-small-hackathon/microfactory-lab has been in RUNTIME_ERROR since June 15. Startup fails at hf-mount with exit code 0 and an empty reason. The Space is unresponsive and cannot be
debugged from the outside.
Root cause: a vestigial volume. build-small-hackathon/microfactory-lab-storage mounted to /data. The bucket exists. It is 0 bytes. 0 files. Created during initial setup, never populated, never removed. The app does
not read from /data at all. HF's mount step hits the empty bucket and dies quietly. No error message because there is no error to report: the mount just does not complete.
Proof by duplication. Cloned the Space to my personal namespace. HF duplication does not carry volumes, so it boots clean. Same code, same vars, same secrets. Reached RUNNING on ZeroGPU + LoRA v3 QAT immediately.
Parity confirmed byte-identical: 128 files, aggregate sha256 cafe646b83e83611e29cf94b63b1abc3ca0abf4b296b59cafc5480caaed9025b. The only diffs are the README duplicated_from line and .gitattributes, both expected
from the clone operation.
Local OFFLINE baseline also solid: all 11 core tests pass, demo runs the full advise loop correctly. The code was never the problem.
The fix for the org Space is one command: detach the volume and factory reboot. The app needs no mount. That requires org owner access. In the meantime the duplicate serves as the working live Space:

Lesson: a volume you attach and forget about is a time bomb. If your app does not read from it, remove it. HF will not tell you the mount failed. It will just not start.
