memory: snapshot — FV recovered, fv-ml1 seat reorg, gen-large blocked on orca runtime

FV colo recovered 2026-09-13 midday (chassis on PDU, firewall on the Eaton 5P1000,
GPU caps 275W/card). All-night fv-ml1 seat reorganization:

- flash-next gained MTP k=3 (campaign measured it a win here, +52% at conc=1),
  inverting vLLM's 4xH100 recipe; KV 14->10 GiB.
- gen consolidated onto flash-next (all 8 gen/summarizer/classifier/judge aliases
  repointed); 27B dense gen seat retired, 38 GB freed on GPU0.
- char-rp restored to the in-house MeroMero-v2-31B dense heretic (was serving a
  leftover-test RedHatAI 26B); char-rp-fast is the deliberate speed tier.
- Sentinel-R3 (SFT pentest finetune) served for an A/B vs mog-sec, then dflash k=7
  cut over after measuring it beat MTP (2.40 vs 2.18 acceptance, ~121 tok/s warm).

gen-large is intentionally DOWN: the orcarouter weight-only NVFP4 build downloaded
(170 GB, verified) but no mainline vLLM loads its compressed-tensors qwen4_exp PLE;
the third-party backport was vetted and is unfit (old-hardware fork, no Blackwell
image). Runtime decision pending -- this is the resume point.

Also this session: vh/infra-reference repo, scripts/seat-inventory.py + daily drift
alarm, OPNsense API reference vendored, secrets shed from a prior scratchpad.

Leaves the fv-to-ana-nat files (another session's) and graphify-out untouched.
