+# 021: KPI status check
+
+Goal: record fleet spend/limit metrics.
+
+Steps:
+1. Run `box kpi status`.
+2. Record per-node spend vs limits and any nodes near caps.
+
+Done criteria: result notes below list per-node spend/limit
+lines, or the exact error if the command fails.
+
+Result notes (append below before moving to done/):

+- 2026-10-07, builder muse--runtime--roles: `box kpi status` OK, all
+  routes ONLINE. QUOTA/CALLS: muse 100% 106(106v); pip 100% 40(29v);
+  646 100% 494(429v); opm 100% 2601(1905v); dev 33% 2(1v);
+  def 26% 0(0v). Efficiency: HIGH for muse/646/opm, MODERATE pip,
+  LOW dev/def. Four nodes sit at 100% quota — flagging as possibly
+  near caps (operator: `box kpi report <node>` for advisories).
