Lemma Critical Brief

threat intelligence
× proof layer.

Structured analysis of incidents across AI, cryptographic infrastructure, supply chain, and regulatory attributes — read through the Detection ≠ Proof thesis . Each Brief makes the failure primitive explicit and identifies the structural gap that hardening detection alone cannot close, then connects it to the pre-execution attestation design.

About this collection

Lemma Critical Brief is a structured-incident-analysis reference collection from Lemma. Each Brief covers one incident across nine sections (TL;DR + §1–§8) , structuring the failure primitive and the structural gap that detection alone cannot close, and connecting them to the pre-execution attestation design. Series scope, citation conventions, and editorial process are consolidated on the Methodology page.
