Is _registrationMetaEvidence and _clearingMetaEvidence available on-chain?

[marsrobertson]

It appears to me that event is emitted:

• available on the front-end (can listen to events)
• not available on-chain (cannot listen to events)

tcr/contracts/LightGeneralizedTCR.sol

Lines 781 to 819 in 72e547e

Or maybe there is some other way and I'm missing something?
