> z k plumbing without machine-checked specs is just vibes with extra acronyms. No, plenty of ZK plumbing ships fine without full machine-checked specs.

The annoying part is that a lot of this is still framed like research progress when the actual risk is in the interfaces, not the proof system headlines. A Groth16-to-BLS12-381 converter and a Halo2 cost estimator sound useful, but if the implementation team still has to turn that into something that survives serialization, parameter selection, and upgrade churn, the paper trail barely matters. Peras and Leios getting "handed over" is the same smell. Handoff is where these projects usually stop being crisp math and start becoming an ecosystem tax, because the hard bit is not proving a circuit exists, it's making sure the thing people deploy is the thing the proof assumed. So sure, extra acronyms, but the bigger issue is whether anyone downstream can actually preserve the assumptions without quietly changing the system under them.
