Judgment continuity, pressure accumulation, and unresolved exposure surfaces

CybersecurityHQ weekly brief.

CybersecurityHQ now operates as an External Cybersecurity Judgment of Record. We issue dated, versioned judgments intended for reference in accountable security decisions.
Record update: The CybersecurityHQ Record is now live.
This repository contains active judgments, continuity confirmations, and evidentiary depth referenced in Weekly Briefs.
The current judgment on regulatory accountability concentration remains intact. Judgment reference: CHQ-J-2026-05
Several developments this past week created the impression that enforcement pressure is fragmenting again: spread across AI guidance, third-party oversight language, and identity responsibility splits. That reading is convenient, but wrong.
What actually accumulated was further confirmation that ambiguity is no longer being resolved upstream. Oversight bodies are formalizing shared responsibility without clarifying control ownership, which shifts exposure onto whoever is expected to reconcile regimes after the fact. Nothing emerged that reduces this burden. What did increase is the expectation that organizations can demonstrate governance continuity even when authority is distributed.
This judgment does not resolve how individual regulators will enforce first, or where test cases will appear.
Evidentiary depth: Control-plane accretion at the MCP layer
If asked today to demonstrate governance ownership across systems you do not fully control, what artifact would you actually produce?
