From f861f3cfb59a4702075a67c9bc8f6d67b1d9911f Mon Sep 17 00:00:00 2001 From: vasilito Date: Tue, 28 Jul 2026 06:25:54 +0900 Subject: [PATCH] docs(driver-manager): document Round-6 N20 audit + remove 3 stale docs Adds 5.10.4 Round-6 summary section to DRIVER-MANAGER.md covering N20-E1 (error_channel OOM cap), N20-E2 (6-variant decode), N20-A4 (aer BDF validation), N20-S6 (heartbeat log failures), and N22 (stale doc removal). Updates last-updated header and test count (164->166). Removes three orphaned docs that had zero references in the repo and were last-modified Jul 10-14 vs every other doc Jul 26-27: BLUETOOTH-IMPLEMENTATION-PLAN.md, CUB-PACKAGE-MANAGER.md, and USB-VALIDATION-RUNBOOK.md.
