The FV edge firewall was not backed up anywhere. Its config now lands in
/var/lib/restic/stage/fv-gateway-config.xml via ana-docker's pre-backup hook,
so the existing 01:00 restic snapshot captures it. ana-docker is one of the
three egress addresses the firewall's WAN allowlist permits, which is why the
pull lives there rather than with the FV hardware — a site that has lost power
cannot back itself up, and FV lost power two days ago.
Non-fatal by design: an unreachable firewall must not abort the nightly
database dumps. But a bad pull must not be promoted either. The summary loop
only rejects EMPTY staged files, and this endpoint answers an auth failure
with a perfectly non-empty HTML error page — which would have been backed up
as a firewall config that is the right size and restores nothing. The block
checks the body really contains <opnsense> and writes nothing otherwise.
Three tests cover it, including the HTML-error-page case. The first draft of
those tests was worthless: _fv returned a Path out of a TemporaryDirectory
context, so the tree was deleted before the assertions ran and every
exists()-is-False check passed regardless of what the script did. Only the
positive test failed, which is the sole reason the broken negatives were
caught. They now snapshot inside the tempdir's lifetime, and the docstring
says why.
Also records two OPNsense API lessons in docs/pfi/opnsense-api-reference.md:
endpoints are actions and must never be probed for existence by POSTing at
them — that is how /api/core/system/reboot took the FV site dark for 3.5
minutes while looking for an apply call this same file already documented —
and the apply step is service/reconfigure, which auth/user notably lacks, so
an API-only key edit persists in config.xml and does nothing until the OS user
sync runs at boot.
Credentials in /etc/restic/fv-gateway.env (root:600), template committed,
values vaulted as fv-gateway/opnsense-api-{key,secret}. Pre-change config
snapshot vaulted as fv-gateway/config-backup-20260914.
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.
