From 3361f83e14265d8d5b8503f468ad44b95b75088a Mon Sep 17 00:00:00 2001 From: Robert Allan James Date: Sat, 15 Aug 2026 07:38:18 -0400 Subject: [PATCH] FABRIC-2.md: split Section F triage into documentation and code/action tracks MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Per Captain Bob's request: separate the pre-Artemis closeout triage into two independent tracks (F.1 documentation, F.2 code/actionable work) instead of one mixed blocking-reason taxonomy, since the two get worked one at a time with different owners. F.3 adds a condensed punch list distilled from both tracks. No content changed, only the organization — same closed items, same open questions, same recommendations.
