From a9232f546d5f6ea6a3fab1ef883216ee31f0affd Mon Sep 17 00:00:00 2001 From: Copilot <223556219+Copilot@users.noreply.github.com> Date: Fri, 19 Jun 2026 17:30:46 -0500 Subject: [PATCH 01/12] docs: rename self-assigned CVE IDs to internal JG-ADV advisory format Self-found project issues were labeled CVE-2026-001/002/003. CVEs are issued by CNAs, not projects; the labels read as inflation to a security-literate audience. Rename to internal advisory IDs (JG-ADV-2026-001/002/003, numeric mapping preserved) across all docs, and add a one-line disclaimer at first use in README.md and THREAT_MODEL.md. Docs only; no code/logic touched.
