Captures the Fountain Valley cutover as executed rather than planned: fv-ml1
live on 10.251/16 and serving, BMC recovered after finding it was tagging
802.1q VLAN 250 into an untagged port, and the corrected four-GPU / 391 GB
count that invalidates prior sizing assumptions.
Also records two things that cost real time and would cost it again: OPNsense
write APIs need an X-CSRFToken scraped from a script block, not a hidden form
input, and a 403 that coincides with the box going down looks exactly like a
successful reboot.
Auto-archived 8 settled entries (Recent decisions: 8). The index stays over
the 300-line cap at 385 because the guards hold -- nearly every remaining
dated entry is under 14 days old or carries open deferred work, and an
over-cap file that keeps live decisions beats a scannable one that lost any.
