+The current promotion-candidate artifact is evidence accounting only. It has
+28 rows total: 8 `evidence-ready` rows with virtual HAL source-derived
+browser/release evidence, and 20 `inventory-ready` skipped main-program rows.
+Every row keeps `promotion_allowed=0`, so the inventory baseline remains
+`28/28/131/0`. The companion `evidence-expansion-candidates.tsv` artifact has
+13 rows queued for future browser diagnostics binding, also with
+`promotion_allowed=0`.

+SDK and workflow-overview release URL summaries expose the current
+`evidence-ready` layer as dashboard fields: `evidence-ready-candidate-rows=8`,

+`evidence-ready-candidate-preview-gcode=linuxcnc/configs/sim/qtdragon/qtdragon_multi_joint/on_abort.ngc`,
+`evidence-ready-candidate-promotion-allowed=0`, and
+`evidence-ready-candidate-baseline-changing=no`. These fields are visibility
+for existing source-derived browser/release evidence, not permission to change
+the Node inventory baseline.
