It should probably be integrity-protected using the work that @boocmp and @bridiver are doing.

@diracdeltas this uses the same component we already use for regular NTT. @boocmp and @bridiver can you please point me to an GitHub issue, to understand how it may impact us, and any rough timelines if possible? Thanks

If you want to add the verified contents metadata then you need to pass the verifiedContentsKey (it's available in the common script options) to the function that generates the component content then use util.generateVerifiedContents(...) before calling the util.generateCRXFile(...).You can see how it was done for adblock here
