+**The nodes are NOT hardware-symmetric.** Node 1 has a ~2011 SATA SSD with real wear; node 2 has a
+healthy modern NVMe. §2 requires an identical disk layout across all three because Longhorn replica
+placement assumes symmetry — so this is a live input to the disk decision, not a footnote. Node 2's
+NVMe is the drive node 1 should have had.
 
 Dev nodes for comparison: 8 vCPU / 24 GiB / Debian 13, **two** dedicated data disks (Longhorn + etcd).
 
@@ -108,9 +115,6 @@ To investigate, cheapest first:
 - [ ] **Set `After Power Loss=Power On`** regardless of the memory question — §1 requires it and
       node 2 currently violates it.
 - [ ] Clear CMOS / load setup defaults on node 2 to force a full memory retrain, then re-check.
-- [ ] Compare node 2's BIOS settings against node 1 directly. Look for a memory remap / "Above 4G
-      decoding" style option, and for any memory-limit or 32-bit-addressing setting.
-- [ ] Clear CMOS / load setup defaults on node 2, then re-check `MemTotal`.
 - [ ] Reseat the DIMM; try it in DIMM3; try it in node 1 (swap test) — that isolates DIMM vs slot
       vs board in one move.
 - [ ] `memtest86+` if the above do not resolve it.
