Which module does index.js import first?
risk LOW
model
`index.js` imports `./lib/reexport` first. It's also the only import, and it pulls in `TIMEOUT_MS` from it.

Trace where the exported constant TIMEOUT_MS is finally defined and give me its value.

final reply
I couldn't complete this — I kept running into a problem (Trace where the exported constant TIMEOUT_MS is finally defined and give me its value.). You may want to retry or rephrase what you need.

Full harness trace — supervisorOff · seed 3

The harness runs on every turn. Below is what it did this run — the layers it consulted and why each did or didn't act, the tool-use decisions it made, and the nodes it walked. Both arms run the same machinery unless the feature under test changes it.
