I re-downloaded the latest version of TinyTorch. To maintain consistency with my previous progress, I directly used the commands: tito module start 01, tito module complete 01, tito module start 02, tito module complete 02, tito module start 013, tito module complete 03. However, it failed during testing—this is the same issue I encountered yesterday.

Thanks for reporting this @wz1114841863! You've found a real bug in the workflow.

Root Cause: The integration tests were running BEFORE the module was exported. Since integration tests import from tinytorch.core.layers (which only exists after export), they always failed on a fresh install.

The Fix: I've reordered the workflow in commit 1f7a2bb:

Old Order	New Order
1. All tests	1. Unit tests
2. Export	2. Export
3. Track progress	3. Integration tests
	4. Track progress

Now:

Unit tests run first (they test your source files directly)
Export happens next (creates tinytorch/core/layers.py)
Integration tests run last (they can now find the exported module)

To get the fix: Re-download the latest version:

curl -fsSL https://tinytorch.ai/install | bash

I will do a new bug fix release once all the tests pass.

Then try tito module complete 03 again. Let me know if you hit any other issues!
