From 1ed03350e36dfd94dd10c5d1269fc5fc73d325b8 Mon Sep 17 00:00:00 2001 From: Brian Torres Date: Thu, 15 Oct 2026 01:02:16 -0700 Subject: [PATCH] Docs: record the D4 white-level fix in the status lines and file-format revision history (#5978) AGENTS.md asks for the status line and revision history of the parity docs to move with the change: gaps.md and file-format-parity.md now carry it.
