Run outputs moved to logs/ (incl. sda partition-table backup). New from the 15:57-16:03 parallel session: 16-grow-root-online.sh (RAN: / = 431G online, swap removed by design — GROW-ROOT-RUNBOOK superseded) and 15-docker-to-data2.sh (staged, not run). README/NEXT/RUNBOOK/REBUILD reflect current reality. Moot rdp-testprep timer removed from the VM. Details: https://projects.knownelement.com/issues/615

# 16-grow-root-online.sh — kill swap (8.8G, 0B used, 47G RAM) and grow
|
|
# the ext4 root ONLINE to fill the 438G NVMe (~158G of trailing free
|
|
# space becomes contiguous with sda1 once sda2/sda5 are deleted).
|
|
# Charles authorized swap removal 2026-09-01; agent wrote the script
|
|
# (agent's tool layer blocks sudo). ONLINE-ONLY: no reboot, no unmount,
|
|
# no data movement (ext4 grow is forward metadata only).
|
|
#
|
|
# Protocol: gates -> table backup -> swapoff+fstab -> delete sda5+sda2
|
|
# -> rewrite table with sda1 filling the disk (start sector UNCHANGED)
|
|
# -> partx online update -> resize2fs -> verify.
