vh 50c85e0e8a feat(litellm): load-share embed/rerank across esh-ml1 + nh3-ml1 with intra-group failover
- qwen3-embedding and reranker: second deployment on nh3-ml1 (config);
  reranker-a3-bge-v2-m3: second DB deployment via /model/new.
- router_settings.enable_weighted_failover: true. Only the three
  multi-deployment groups are affected.
- Measured by stopping nh3-ml1 TEI: without failover 7/40 embeds 500'd;
  with it rerank 80/80, embed 38/40 at onset and 60/60 over a 34 s outage;
  nh3 rejoins rotation after restart. Split 12/28 embed, 22/18 rerank.

vh 5960526c3f feat(nh3-ml1): second TEI embed/rerank backend live on nh3-pve; parity-verified vs esh-ml1
NH3 site visit done: Secure Boot off, iGPU restored as boot VGA, AMT port cabled.

- nh3-pve: NVIDIA 580.178.04 (DKMS, open modules) via pve-nvidia-host.yaml.
- nh3-ml1 = CT 109 @ 10.100.50.80 via gpu-lxc.yaml; embed-rerank (TEI 1.9.4)
  deployed with HOST_NAME/HOST_IP labels.
- Parity vs esh-ml1 (1,126 texts, 2 runs/host, controls): embed cosine min
  0.999993 = own noise floor; overlap@10 1.000 vs MRL-256 positive control
  0.684; rerank top-1 1.00, max diff 0.0014 vs floor 0.0020. On-box speed
  identical within rep spread.
- gpu-lxc.yaml: first step upgrades lxc-pve to >= 6.0.0-2 (Proxmox fix #7006).
  With 6.0.0-1 every docker run in a nesting CT failed on runc 1.5's sysctl
  reopen; applied on nh3-pve (one package).
- pve-nvidia-host.yaml: document that the headers meta drags in the newest
  kernel (nh3-pve went 6.8.12-11 -> -43 at the next reboot).
- Monitoring: Beszel NVIDIA agent + 5 alerts, Kuma #29/#30, Homepage
  nh3-ml1-docker, Dozzle agent (hub 8 clients). DNS nh3-ml1.nh3.internal.
- nh3-pve README: SB/IGFX/driver/kernel state, btmtk oops on -4x kernels,
  AMT cabled but unreachable on the network.

Gateway routing to nh3-ml1 is not changed.

vh 7bdac80878 feat(embed-rerank): TEI is the fleet embed/rerank engine; esh-ml1 sole backend; retire fv-ml1 seats
Prime, 2026-09-25: TEI serves embedding + reranking for esh-ml1 and the fleet
from now on; fv-ml1 retires both once esh-ml1 is up.

- stacks/embed-rerank: vLLM -> TEI 1.9.4 (89- Ada build), same ports
  8001/8013, fail-closed truncation (--auto-truncate false; embed
  --max-batch-tokens 32768).
- litellm: qwen3-embedding -> esh-ml1 only (hosted_vllm/, unchanged address);
  reranker -> huggingface/ provider at :8013 (hosted_vllm/ 422s on TEI's
  `texts` body). DB alias reranker-a3-bge-v2-m3 patched to the same target.
- Verified via the gateway against the retiring fv-ml1 seats: embed cosine
  median 0.999927 (n=203); rerank top-1/top-3 29/30.
- stacks/vllm: vllm-embed and vllm-rerank-a3 removed (containers retired on
  fv-ml1, GPU 1 freed ~6.1 GB); reward + coder unchanged.
- Bake-off record moved to docs/pfi/embed-rerank-tei-vs-vllm-bakeoff.md;
  CLAUDE.md gains the TEI convention.

vh 5402568b76 feat(esh-ml1): RTX 2000E Ada on esh-pve serves embed + rerank as a LiteLLM failover
esh-pve: NVIDIA 580.178.04 (open modules, DKMS) installed on the host from
NVIDIA's .run and loaded live, no reboot. nvidia-persistenced unit creates the
device nodes before pve-guests; the T400's vfio-pci ids and `blacklist nvidia`
retired. playbooks/esh-pve-nvidia-host.yaml.

esh-ml1: CT 110, unprivileged Debian 12, 10.0.50.80, GPU nodes via devN,
NVIDIA userspace from the same .run (--no-kernel-modules), docker-ce +
nvidia-container-toolkit (no-cgroups). playbooks/esh-ml1-lxc.yaml. Not in the
vzdump job on purpose. DNS esh-ml1.esh.internal.

stacks/embed-rerank: Qwen3-Embedding-0.6B :8001 + bge-reranker-v2-m3 :8013 on
the same vLLM v0.24.0 digest and flags as fv-ml1. Measured parity: embed
cosine FV-vs-ESH median 0.999908 (min 0.999772), inside both self-noise
floors; rerank max |delta| 0.000145 vs floor 0.000181, identical ranking.

litellm: qwen3-embedding and reranker gain an esh-ml1 deployment at order 2
behind fv-ml1 (order 1). Order fallback proven with throwaway groups:
refused primary +0.15 s, host-down primary ~18.7 s per call, dead-only 500.

Also: repaired the DB-only alias reranker-a3-bge-v2-m3, dead since the
fv-ml1 relocation (still named 10.250.50.54); documented the third
unkillable homepage wedge on esh-docker-vm.
