[SOLVED] eMudhra emBridge detects DSC token but certificate list is em

I recently ran into an issue using an Indian eMudhra Digital Signature Certificate (DSC) on Arch Linux.

Symptoms:

• USB token detected
• pkcs11-tool could list the certificate
• Vendor utility could read the certificate
• emBridge detected the token
• MCA portal showed the token

But the certificate list was always empty.

After debugging the entire stack (PKCS#11, emBridge, and the Linux compatibility issues), I managed to get everything working.

I documented the investigation and solution here:

Hopefully this saves someone else from spending a weekend debugging.
