From 795e160cc33f07c3c2e1a10fb361b39ea7ffc165 Mon Sep 17 00:00:00 2001 From: Tom Boucher Date: Mon, 30 Mar 2026 15:48:15 -0400 Subject: [PATCH] fix: treat ghost milestones as ineligible for parallel execution (#2501) (#3268) Milestones with no registry entry (ghost directories with no planning files) were falling through to eligible status due to the fallback `entry?.status ?? "pending"` combined with empty deps. Now explicitly classified as ineligible with "no planning data" reason before any status/dep checks run.
