release: update go.mod for v1.7.0

* Revert "fix(network): prime host neigh with gateway port MAC on centralised EIP attach"

This reverts commit f7446c69c6.

* fix(network): round-robin external pool cursor so a released IP is not reused instantly

The static external pool handed out the lowest free address and freed IPs
immediately on release, so a just-released EIP was reassigned within ~0.6s. A
recycled EIP front-end is unreachable from the same host: the kernel still
holds the prior owner's ARP binding (or a negative cache after the neigh
flush) and OVN does not answer the re-ARP in time, so the neighbour entry
settles to FAILED (EHOSTUNREACH). This surfaced as EKS TestEKS/KubectlGetNodes
failing in single-node CI once #315 routed kubectl through the cluster NLB's
external EIP. Dev never hit it — it uses DHCP-random addresses.

Add a persisted per-pool cursor: allocation resumes one past the last address
handed out and wraps at RangeEnd, so a freed IP is not reused until the cursor
cycles the whole range. Empty cursor (fresh pool / older KV record) starts at
RangeStart, preserving lowest-free order for the first cycle — backward
compatible, no migration.

* ci: drop e2e-eks from default e2e suites

EKS data-plane subtest (TestEKS/KubectlGetNodes) is a persistent flake on
single-node CI — a freshly-attached centralised EIP is intermittently
unreachable from the host (no route to host to the cluster endpoint), which
fails the whole E2E run and blocks unrelated suites. Remove e2e-eks from the
default SUITES so PR/push runs no longer gate on it. The e2e-eks target and
the workflow_dispatch suites input are unchanged, so EKS stays runnable on
demand and via make e2e-all.

+### Instance Has Public IP But No Internet
+
+The instance shows a public IP in `describe-instances` but cannot reach the
+internet, and inbound connections hang. The usual cause is a missing default
+route: the subnet's effective route table has no `0.0.0.0/0` route to the IGW,
+so Spinifex gates the subnet with a drop policy.
+
+```bash
+# Find the route table that applies to the subnet and check its routes

+  --query 'RouteTables[0].Routes'
+# Expect a route with DestinationCidrBlock 0.0.0.0/0 and a GatewayId of igw-...
+```
+
+If the subnet has no explicit association it falls back to the VPC's main route
+table — check that one too, then add the route to whichever table applies:
+
+```bash
+aws ec2 create-route --route-table-id $RT \
+  --destination-cidr-block 0.0.0.0/0 --gateway-id $IGW
+```
+
+On the host, the drop policy installed when a subnet lacks an IGW route appears
+as a `Logical_Router_Policy` on the VPC router:
+
+```bash
+sudo ovn-nbctl lr-policy-list vpc-$VPC
+# A drop policy matching the subnet CIDR means the subnet is gated.

+Instances in a private subnet get a private IP only and are not reachable from your network.

+
+## Overview
+
+This document serves as a tutorial for setting up multi-tenant AI workloads with Spinifex. The reference architecture for this tutorial is the Supermicro H14 platform - specifications listed below.
+
+The H14 chassis comes equipped with **8× AMD Instinct MI350X** (288 GB HBM3e each, 2.3 TB total). We used Spinifex to provision three isolated VMs, each assigned 2× MI350X via direct PCIe passthrough, and ran three computationally intensive workloads simultaneously: a YOLO11x vision model, a Qwen3-VL 235B FP8 vision language model, and a Llama 3.3 70B large language model.
+
+<p><video src="https://iso.mulgadc.com/clipped-demo.mp4" controls width="100%" style="border-radius:6px"></video></p>
+
+### Platform
+
+| Component | Specification |
+|---|---|
+| **Bare-metal host** | Supermicro H14 |
+| **Host OS** | Ubuntu 24.04 LTS or Debian 13 (minimum) |
+| **Orchestration** | Spinifex — EC2-compatible bare-metal API |
+| **Guest OS** | Ubuntu 26.04 LTS |
+| **GPUs** | 8× AMD Instinct MI350X (288 GB HBM3e each, 2.3 TB total) |
+| **GPU passthrough** | PCIe passthrough via vfio-pci |
+| **Instance type** | `g7e.12xlarge` — 2× MI350X per VM |
+| **Container runtime** | Docker (with ROCm device access) |
+| **Inference runtime** | vLLM (`rocm/vllm` image) |
+| **VM network** | Internal VPC, 192.168.10.0/24 |
+| **Block storage** | Viperblock — EBS-compatible, local NVMe-backed |
+
+Spinifex runs on the bare-metal host and exposes an EC2-compatible API to any standard `aws ec2` tooling. Guest VMs receive their GPU allocation at the hardware level — each VM's OS sees the MI350Xs as native PCIe devices with no virtualisation layer in the data path. Workloads across VMs share no GPU memory, no address space, and no network segment except through the VPC.
+
+GPU passthrough requires a host kernel and OS that supports vfio-pci. Ubuntu 24.04 LTS (kernel 6.8+) and Debian 13 (kernel 6.12+) are the tested minimum baselines for the host. Guest VMs run Ubuntu 26.04 LTS.
+
+## Prerequisites
+
+- Supermicro H14 with 8× AMD Instinct MI350X installed
+- Host OS: **Ubuntu 24.04 LTS** (kernel 6.8+) or **Debian 13** (kernel 6.12+) — minimum for vfio-pci support
+- Spinifex installed and all services running (`systemctl status spinifex.target`)
+- AMD GPU AMI registered (`ami-ubuntu-amd-gpu`) — Ubuntu 26.04 LTS with ROCm-compatible kernel
+- AWS CLI configured with `AWS_PROFILE=spinifex` pointing at the Spinifex endpoint
+- SSH key pair imported into Spinifex, VPC and security group created (see [Launching Instances](/docs/launching-instances))
+
+GPU passthrough must be configured before launching GPU instances. This is a one-time step per host.
+
+```bash
+# Detect GPUs and bind to vfio-pci (requires reboot)
+sudo spx admin gpu setup
+
+# After rebooting — confirm passthrough is active and signal the daemon
+sudo spx admin gpu enable
+```
+
+`spx admin gpu setup` blacklists the AMD driver on the host and binds each GPU to `vfio-pci`. After reboot, `spx admin gpu enable` verifies the binding and makes the GPU pool available to `RunInstances`.
+
+<img src="../../../.github/assets/images/gpu-enabled.png" alt="Spinifex console confirming PCIe passthrough is active for each GPU">
+
+To check available GPU instance types:
+
+```bash
+export AWS_PROFILE=spinifex
+aws ec2 describe-instance-types \
+    --query 'InstanceTypes[?GpuInfo].[InstanceType,GpuInfo.Gpus[0].Count,GpuInfo.Gpus[0].Name]' \
+    --output table
+```
+
+## Instructions
+
+### 1. Provision the VMs
+
+Each VM was provisioned using standard AWS EC2 CLI commands — the only change from a normal AWS workflow is `AWS_PROFILE=spinifex`, which redirects the CLI to Spinifex's local EC2-compatible endpoint instead of AWS:
+
+| VM | Instance type | GPUs | Role | Model |
+|---|---|---|---|---|
+| `vm-yolo` | g7e.12xlarge | 2× MI350X | Real-time object detection | YOLO11x |
+| `vm-vlm`  | g7e.12xlarge | 2× MI350X | Multi-modal scene analysis | Qwen3-VL 235B FP8 |
+| `vm-chat` | g7e.12xlarge | 2× MI350X | Conversational LLM | Llama 3.3 70B |
+
+Six of the eight available MI350Xs are claimed here; the remaining two stay idle on the host, available for a fourth tenant without touching the existing three.
+
+```bash
+export AWS_PROFILE=spinifex
+
+# vm-yolo — YOLO11x object detection, 200 GB disk
+YOLO_ID=$(aws ec2 run-instances \
+    --image-id ami-ubuntu-amd-gpu \

+echo "vm-chat launched: $CHAT_ID"
+
+# Wait for all three to reach running state
+for ID in "$YOLO_ID" "$VLM_ID" "$CHAT_ID"; do
+    aws ec2 wait instance-running --instance-ids "$ID"
+    echo "$ID is running"
+done

+echo "vm-vlm:  $VLM_IP"
+echo "vm-chat: $CHAT_IP"
+```
+
+### 2. Verify GPU access
+
+Once SSH is available, confirm both GPUs are visible inside each VM:
+
+```bash
+ssh -i ~/.ssh/spinifex-key ubuntu@$CHAT_IP 'lspci | grep -i amd'
+```
+
+Or install and run `amd-smi`:
+
+```bash
+ssh -i ~/.ssh/spinifex-key ubuntu@$CHAT_IP \
+    'curl -fsSL https://repo.radeon.com/rocm/rocm.gpg.key | gpg --dearmor | sudo tee /etc/apt/keyrings/rocm.gpg >/dev/null && \
+     echo "deb [arch=amd64 signed-by=/etc/apt/keyrings/rocm.gpg] https://repo.radeon.com/rocm/apt/6.3 noble main" | sudo tee /etc/apt/sources.list.d/rocm.list && \
+     sudo apt-get update -qq && sudo apt-get install -y -q amd-smi-lib && \
+     amd-smi list'
+```

+
+Two MI350X entries with distinct UUIDs confirm direct PCIe passthrough is working.
+
+### 3. The orchestration layer
+
+Spinifex provides an EC2-compatible API on bare metal. The relevant capabilities for this demo:
+
+- **Multi-GPU claim per VM.** Each `g7e.12xlarge` requires two PCIe addresses claimed as a unit. Spinifex queries the available GPU pool on the host and assigns them to the guest VM at creation time, rolling back if the full allocation cannot be satisfied.
+- **PCIe passthrough via vfio-pci.** All 8 MI350Xs are bound to `vfio-pci` on the bare-metal host. Each VM gets its GPUs at the hardware level.
+- **Internal VPC (192.168.10.0/24).** VMs communicate directly without traversing the host's public network.
+
+The result: three completely independent EC2 instances, each running their own separate workloads using only the GPU resources they were allocated.
+
+### 4. Test methodology
+
+Two capture runs were made against the same workload script: **30 s baseline** (YOLO and VLM models running, no chat load) → **25 scripted Llama chat prompts** at 15 s intervals → **30 s settle tail**.
+
+The only difference between the two runs was tensor parallelism:
+
+- **Demo 1 (TP=1):** each VM uses one of its two allocated GPUs. The second sits idle.
+- **Demo 2 (TP=2):** each VM shards its model symmetrically across both GPUs using AMD Infinity Fabric (XGMI).
+
+| Metric | TP=1 baseline (Demo 1) | TP=2 (Demo 2) |
+|---|---|---|
+| Wall clock | 613 s | 600 s |
+| YOLO avg fps | 16.91 (min 15.3 / max 18.0) | 17.09 (min 15.6 / max 18.1) |
+| Qwen peak tok/s | 61.7 | 53.0 |
+| Llama peak tok/s | 36.4 | **53.1** |
+| Both GPUs active (chat VM) | no — GPU 1 idle | **yes — symmetric** |
+| VRAM per GPU (Qwen) | 259 GB on one, 0.3 GB on other | 241 GB on **both** |
+| VRAM per GPU (Llama) | 261 GB on one, 0.3 GB on other | 248 GB on **both** |
+
+### 5. Results
+
+### Inter-tenant isolation
+
+The charts below show the three independent workloads spiking activity on their associated GPUs, measured in GFX utilisation and power draw. YOLO average FPS stays at ~17 despite utilisation in the YOLO VM never exceeding 20%, indicating a bottleneck in networking or encoding rather than inference. Each chart highlights workload independence — pulses of GPU activity share no correlation across VMs.

+
+Power draw per VM during Demo 2.
+
+### Single vs double GPU
+
+When TP=2 is enabled, each VM shards its model symmetrically across both GPUs. Inside the chat VM, both GPUs pulse together on every request, each holding exactly **248 GB of VRAM** (weights split + KV cache shards). With TP=1, GPU 1 sat at 0% for the entire run.

+
+### vLLM generation throughput
+
+With TP=1, Qwen peaks at ~60 tok/s and Llama caps around 35 tok/s — both compute-bound on a single MI350X. Enabling TP=2 lifts Llama's peak to ~50 tok/s (+47%) as generation is distributed symmetrically across both GPUs. Qwen's throughput is slightly lower under TP=2 due to collective overhead on the shared-memory transport.

+
+### 6. Teardown
+
+```bash
+# Stop workloads on each VM
+for IP in "$YOLO_IP" "$VLM_IP" "$CHAT_IP"; do
+    ssh -i ~/.ssh/spinifex-key ubuntu@$IP 'docker stop $(docker ps -q)' || true
+done
+
+# Terminate all three instances — releases 6× MI350X back to the Spinifex pool
+aws ec2 terminate-instances --instance-ids "$YOLO_ID" "$VLM_ID" "$CHAT_ID"
+```
+
+The six MI350Xs are immediately returned to the pool once the instances terminate, ready for a new allocation without touching the host.
+
+### 7. Conclusion
+
+This tutorial demonstrates how Spinifex can turn a single bare-metal chassis into a multi-tenant AI serving platform. Spinifex utilises the flexibility of PCIe passthrough to allocate GPU resources in whichever configuration is required by the workload/s.
+
+Importantly, it does so with standard `aws ec2` CLI calls — `run-instances`, `describe-instances`, `terminate-instances` — against Spinifex's EC2-compatible endpoint. Teams already operating AWS infrastructure can point their existing tooling at a Spinifex node with a single profile change, against GPUs that sit in their own rack.

+## Overview
+
+### About Trinity
+
+[Trinity](https://www.arcee.ai/trinity) is a family of open-weight language models from [Arcee AI](https://www.arcee.ai), built specifically for production agentic workloads: reliable tool calling, structured JSON output, coherent multi-turn conversations, and long-context reasoning. The family spans four sizes — Nano (6B), Mini (26B), Large Preview (400B), and Large Thinking (400B reasoning-optimised), with consistent capabilities and API surface across all of them. A workflow validated on Nano can be promoted to Large with no prompt changes.
+
+Trinity Large Preview is a **sparse Mixture-of-Experts (MoE)** model. The headline number is 400B total parameters, but only **13B parameters activate per token** — the MoE routing selects a subset of experts for each forward pass, so inference cost is closer to a much smaller dense model than the raw parameter count suggests. The result is a 400B-class model with a **512K token context window** that fits on two high-memory GPUs and generates at competitive throughput.
+
+Arcee has trained Trinity with a heavy focus on agent reliability — function selection accuracy, valid parameter generation, graceful failure recovery, and schema adherence for structured outputs. It is available as open weights on HuggingFace and is natively compatible with vLLM, SGLang, and llama.cpp.
+
+### This guide
+
+This writeup covers running Trinity Large Preview FP8 on a Supermicro H14 bare-metal node via Spinifex — our EC2-compatible orchestration layer. Two AMD Instinct MI350X GPUs (288 GB HBM3e each, 576 GB combined) provide just enough headroom for the FP8 weights plus active KV cache, provisioned and managed with standard `aws ec2` CLI commands.
+
+At that scale the FP8 weights require around 400 GB of GPU memory — more than a single MI350X can hold. This guide covers splitting the model symmetrically across two MI350Xs using vLLM tensor parallelism (TP=2), running on a `g7e.12xlarge` instance provisioned via Spinifex on the H14.
+
+The complete stack:
+
+| Layer | Detail |
+|---|---|
+| Bare-metal host | Supermicro H14, 8× AMD Instinct MI350X |
+| Orchestration | Spinifex (EC2-compatible API) |
+| Instance type | `g7e.12xlarge` — 2× MI350X via PCIe passthrough |
+| Disk | 800 GB (model weights alone are ~400 GB) |
+| Inference runtime | vLLM (`rocm/vllm` Docker image) |
+| Tensor parallelism | TP=2 — model sharded symmetrically across GPU 0 and GPU 1 |

+
+Spinifex runs on the bare-metal host and presents an EC2-compatible API endpoint. Launching a `g7e.12xlarge` atomically claims two MI350Xs from the host's GPU pool and binds them to the guest VM via PCIe passthrough — the guest OS communicates with the hardware directly, with no software virtualisation layer in the data path. When the instance terminates, those two GPUs are immediately returned to the pool.
+
+GPU passthrough requires a host kernel and OS that supports vfio-pci. Ubuntu 24.04 LTS (kernel 6.8+) and Debian 13 (kernel 6.12+) are the tested minimum baselines for the host. Guest VMs run Ubuntu 26.04 LTS, which ships with the ROCm-compatible kernel and userspace expected by the AMD GPU AMI.
+
+## Prerequisites
+
+- Supermicro H14 with at least 2× AMD Instinct MI350X installed
+- Host OS: **Ubuntu 24.04 LTS** (kernel 6.8+) or **Debian 13** (kernel 6.12+) — minimum for vfio-pci support
+- Spinifex installed and all services running (`systemctl status spinifex.target`)
+- GPU passthrough configured — `spx admin gpu setup` (reboot required) then `spx admin gpu enable`
+- AMD GPU AMI registered (`ami-ubuntu-amd-gpu`) — Ubuntu 26.04 LTS with ROCm-compatible kernel
+- AWS CLI configured with `AWS_PROFILE=spinifex` pointing at the Spinifex endpoint
+- SSH key pair imported, VPC and security group created (see [Launching Instances](/docs/launching-instances))
+- Docker installed in the guest VM (included in the AMD GPU AMI)
+- HuggingFace account with access to `arcee-ai/Trinity-Large-Preview-FP8`
+
+GPU passthrough must be configured before launching GPU instances:
+
+```bash
+sudo spx admin gpu setup   # binds GPUs to vfio-pci — requires reboot
+# ... reboot ...
+sudo spx admin gpu enable  # confirms passthrough and makes GPU pool available
+```
+
+## Instructions
+
+### 1. Provision the instance
+
+Spinifex exposes a standard EC2 API on the bare-metal host. The only difference from a real AWS workflow is `AWS_PROFILE=spinifex`.
+
+```bash
+export AWS_PROFILE=spinifex
+
+# Check available GPU instance types
+aws ec2 describe-instance-types \
+    --query 'InstanceTypes[?GpuInfo].[InstanceType,GpuInfo.Gpus[0].Count,GpuInfo.Gpus[0].Name]' \
+    --output table
+
+# Launch a g7e.12xlarge with 800 GB disk
+# Spinifex atomically claims 2× MI350X via PCIe passthrough for this instance type
+INSTANCE_ID=$(aws ec2 run-instances \
+    --image-id ami-ubuntu-amd-gpu \
+    --instance-type g7e.12xlarge \
+    --key-name spinifex-key \
+    --subnet-id <subnet-id> \
+    --security-group-ids <sg-id> \
+    --block-device-mappings 'DeviceName=/dev/sda1,Ebs={VolumeSize=800,DeleteOnTermination=true}' \
+    --count 1 \
+    --query 'Instances[0].InstanceId' --output text)
+
+echo "Launched: $INSTANCE_ID"
+
+# Wait for running state
+aws ec2 wait instance-running --instance-ids "$INSTANCE_ID"
+
+# Get the IP
+INSTANCE_IP=$(aws ec2 describe-instances \
+    --instance-ids "$INSTANCE_ID" \
+    --query 'Reservations[0].Instances[0].PublicIpAddress' --output text)
+
+echo "IP: $INSTANCE_IP"
+```
+
+Once SSH is available, confirm both GPUs are visible:
+
+```bash
+ssh -i ~/.ssh/spinifex-key ubuntu@$INSTANCE_IP 'lspci | grep -i amd'
+```
+
+Or install and run `amd-smi` on the instance:
+
+<img src="../../../.github/assets/images/2gpus.png" alt="amd-smi inside the guest VM confirming two MI350Xs are directly attached, each with a unique UUID">
+
+Two MI350X entries with distinct UUIDs confirm direct PCIe passthrough.
+
+### 2. Pull the vLLM Docker image
+
+```bash
+ssh -i ~/.ssh/spinifex-key ubuntu@$INSTANCE_IP
+
+# On the VM:
+docker pull rocm/vllm:latest
+```
+
+> The `rocm/vllm` image is large (~20 GB). Pull it while the model is downloading in parallel if bandwidth allows.
+
+### 3. Pull the model
+
+Trinity Large Preview FP8 weighs roughly 400 GB, so expect the model download to take some time.
+
+```bash
+# On the VM:
+pip install 'huggingface-hub[hf_xet]'
+hf download 'arcee-ai/Trinity-Large-Preview-FP8' --repo-type model
+
+# Monitor progress — looking for ~400 GB total
+du -sh ~/.cache/huggingface/hub/
+```
+
+The model lands in `~/.cache/huggingface/hub/`. vLLM picks it up automatically from there on serve.
+
+### 4. Run vLLM
+
+Trinity needs TP=2 to fit across both MI350Xs:
+
+```bash
+# On the VM:
+docker run --rm -d \
+    --name trinity \
+    --device /dev/kfd \
+    --device /dev/dri \
+    --group-add video \
+    --ipc host \
+    --network host \
+    -v ~/.cache/huggingface:/root/.cache/huggingface \
+    rocm/vllm:latest \
+    vllm serve arcee-ai/Trinity-Large-Preview-FP8 \
+        --tensor-parallel-size 2 \
+        --dtype auto \
+        --max-model-len 8192 \
+        --gpu-memory-utilization 0.90 \
+        --host 0.0.0.0 \
+        --port 8003
+```
+
+Watch the startup log:
+
+```bash
+docker logs -f trinity
+```
+
+Loading a 400B FP8 model across two GPUs takes **2–4 minutes**. Wait for:
+
+```
+INFO:     Application startup complete.
+```
+
+Then verify:
+
+```bash
+curl http://localhost:8003/health
+curl http://localhost:8003/v1/models | python3 -m json.tool
+```
+
+### 5. Test it
+
+A quick sanity check via the OpenAI-compatible API before running benchmarks:
+
+```bash
+curl http://localhost:8003/v1/chat/completions \
+    -H "Content-Type: application/json" \
+    -d '{
+        "model": "arcee-ai/Trinity-Large-Preview-FP8",
+        "messages": [{"role": "user", "content": "Explain tensor parallelism in three sentences."}],
+        "max_tokens": 256
+    }'
+```
+
+The first request will be slowest — KV cache is cold. Subsequent requests warm up noticeably.
+
+### 6. Dashboard
+
+We created a quick dashboard for a live view of the model's telemetry — throughput, latency, GPU utilisation, VRAM, and KV cache — streamed via SSE from the vLLM metrics endpoint and the GPU stats sidecar.
+
+<p><video src="https://iso.mulgadc.com/trinity-workload.mp4" controls width="100%" style="border-radius:6px"></video></p>
+
+### 7. Benchmark results
+
+Two captures were run against the live model:
+
+- **Chat session:** A short interactive session — low concurrency, variable cadence, 56 s total. Reflects real conversational use.
+- **Scripted benchmark:** 5-minute sustained load driver — rotating batch of 15 long-form technical prompts at 1.5 s cadence. Reflects peak throughput.
+
+| Metric | Chat session | Benchmark (5 min) |
+|---|---|---|
+| Peak tok/s | 67.1 | 67.0 |
+| Avg tok/s (under load) | 18.7 | **52.9** |
+| Avg TTFT | 1668 ms | 758 ms |
+| Min TTFT | 1502 ms | 538 ms |
+| Max TTFT | 1871 ms | 1165 ms |
+| GPU 0 util (avg) | 30.2% | 88.8% |
+| GPU 1 util (avg) | 30.1% | 88.7% |
+| VRAM per GPU | 259.6 GB | 259.6 GB |
+| Avg power (both GPUs) | 664 W | 788 W |
+| Peak power | 828 W | 839 W |
+| GPU temp | 65 °C | 65 °C |
+
+The lower avg utilisation in the chat session reflects idle gaps between conversational turns; peak throughput is identical at ~67 tok/s in both runs, indicating the hardware ceiling rather than a software one.
+
+### Generation throughput
+
+<img src="../../../.github/assets/images/trinity/trinity-throughput.png" alt="Trinity generation throughput — scripted benchmark">
+
+Generation and prompt-ingest tok/s over the 5-minute benchmark. The model sustains ~53 tok/s average at continuous load, peaking at 67 tok/s.
+
+### Per-GPU compute utilisation
+
+<img src="../../../.github/assets/images/trinity/trinity-per-gpu-util.png" alt="Trinity per-GPU utilisation — scripted benchmark">
+
+GPU 0 and GPU 1 track each other closely throughout the benchmark — TP=2 distributes attention and FFN layers symmetrically across both MI350Xs.
+
+### Per-GPU VRAM
+
+<img src="../../../.github/assets/images/trinity/trinity-per-gpu-vram.png" alt="Trinity per-GPU VRAM — scripted benchmark">
+
+Both GPUs hold 259.6 GB — model weights sharded evenly, plus KV cache. 90.2% of HBM3e is occupied at rest, leaving ~26 GB headroom per GPU for active KV cache during generation.
+
+### Per-GPU power
+
+<img src="../../../.github/assets/images/trinity/trinity-per-gpu-power.png" alt="Trinity per-GPU power — scripted benchmark">
+
+Power draw during active generation peaks at ~420 W per GPU, for a combined chassis draw well under the MI350X's 750 W TDP per card. Idle between prompts returns to ~300 W.
+
+### Latency
+
+<img src="../../../.github/assets/images/trinity/trinity-latency.png" alt="Trinity latency — scripted benchmark">
+
+Cumulative average TTFT and E2E latency over the benchmark. TTFT settles to ~758 ms avg once the KV cache is warm; E2E tracks request length as expected.
+
+### KV cache utilisation
+
+<img src="../../../.github/assets/images/trinity/trinity-kv-cache.png" alt="Trinity KV cache utilisation — scripted benchmark">
+
+KV cache occupancy rises as requests pile up during the sustained load phase. The queue depth stays near zero — the model keeps pace with the 1.5 s prompt cadence.
+
+### 8. Teardown
+
+```bash
+# Stop the container
+ssh -i ~/.ssh/spinifex-key ubuntu@$INSTANCE_IP 'docker stop trinity'
+
+# Terminate the instance — releases the 2× MI350X back to the Spinifex pool
+aws ec2 terminate-instances --instance-ids "$INSTANCE_ID"
+```
+
+The two MI350Xs are immediately available to Spinifex for a new workload once the instance terminates.
+
+### 9. Conclusion
+
+Trinity Large Preview demonstrates that frontier-class open-weight models are now within reach of a two-GPU bare-metal setup. The MoE architecture is crucial: 400B total parameters with only 13B active per token means the model generates at ~53 tok/s sustained and peaks at 67 tok/s on a pair of MI350Xs — throughput that would be difficult to match with a dense model of comparable quality at that memory footprint.
+
+Combining this with Spinifex as the infrastructure layer allows teams to own the entire workflow. Provisioning a `g7e.12xlarge` instance, pulling a 400 GB model, and serving it through vLLM took a handful of standard `aws ec2` commands and a single `docker run`. The same workflow runs identically on any Spinifex-managed bare-metal node, with the GPUs returned to the pool when instances terminate.
+
+For teams evaluating Trinity for production agentic workloads — tool calling, structured outputs, long-context reasoning — this represents a credible self-hosted deployment path: open weights, Apache 2.0 license, owned hardware and familiar tooling.

-# Ansible Dev Lifecycle (parallel to bash scripts)
-
-Experimental Ansible-based lifecycle for a single-node Spinifex dev host.
-Lives alongside the existing `scripts/dev-*.sh` and `scripts/reset-dev-env.sh`;
-neither set is removed. Decide which to keep after parity testing.
-
-Plan: `docs/development/improvements/ansible-dev-lifecycle.md` (mulga top-level).
-Bead: `mulga-siv-9`.
-
-## Prerequisites
-
-Venv lives at sub-repo root (`spinifex/.venv/`) — one venv per sub-repo,
-shared by any future python tooling in spinifex. Bootstrap from `spinifex/`:
-
-```
-sudo apt install python3.13-venv
-python3 -m venv .venv
-source .venv/bin/activate
-pip install 'ansible>=9'
-ansible-galaxy collection install -r scripts/ansible/requirements.yml
-```
-
-Then `cd scripts/ansible` to run playbooks — `ansible.cfg` resolves the
-inventory and roles relative to CWD.
-
-## Playbooks
-
-| Playbook | Purpose | Bash parity |
-|---|---|---|
-| `playbooks/dev-preflight.yml` | Dependency + port check | `dev-setup.sh` §checks |
-| `playbooks/dev-teardown.yml` | Wipe state only (no reinstall) | `reset-dev-env.sh` §teardown |
-| `playbooks/dev-install.yml` | Build + install + init + smoketest on clean box | `dev-install.sh` |
-| `playbooks/dev-reset.yml` | Capture settings → teardown → build → install → init → smoketest | `reset-dev-env.sh` (full) |
-| `playbooks/dev-deploy.yml` | Rebuild + swap binaries/microvm artifacts + restart (no setup.sh, no smoketest) | `make deploy` |
-
-Upcoming (not yet implemented):
-
-- `dev-mode-start.yml` / `dev-mode-stop.yml` — parity with `start-dev.sh` / `stop-dev.sh`
-  (lowest priority — deprecated bash scripts, CI-only callers).
-
-## Invocation
-
-```
-ansible-playbook playbooks/dev-preflight.yml
-ansible-playbook playbooks/dev-teardown.yml
-ansible-playbook playbooks/dev-install.yml
-ansible-playbook playbooks/dev-reset.yml
-ansible-playbook playbooks/dev-deploy.yml
-```
-
-Or via `make` (from `spinifex/`):
-
-```
-make ansible-dev-preflight
-make ansible-dev-teardown
-make ansible-dev-install
-make ansible-dev-reset
-make ansible-dev-deploy
-```
-
-### When to use which
-
-- First-time / clean box → `ansible-dev-install`
-- Iterate on Go code, microvm initramfs, lb-agent → `ansible-dev-deploy` (fast)
-- Changed systemd units, helper scripts, logrotate, setup.sh → `ansible-dev-reset` (slow, full rebuild)
-- Need a clean slate without reinstall → `ansible-dev-teardown`
-
-## Variable overrides
-
-Defaults in `vars/defaults.yml`. Override per run with `-e`:
-
-```
-ansible-playbook playbooks/dev-teardown.yml -e spinifex_wipe_ssh_keys=true
-```
-
-Useful overrides:
-
-| Var | Default | What it does |
-|---|---|---|
-| `spinifex_wipe_legacy_home` | `true` | Remove `$HOME/spinifex` (legacy dev-mode path) |
-| `spinifex_wipe_ssh_keys` | `false` | Remove `~/.ssh/spinifex-key*` |
-| `spinifex_wipe_aws_creds` | `false` | Remove spinifex profile from `~/.aws/credentials` |
-| `teardown_process_wait_seconds` | `30` | Grace period for processes to exit |
-| `spinifex_region` | `ap-southeast-2` | Region passed to `spx admin init` |
-| `spinifex_az` | `{{ region }}a` | AZ passed to `spx admin init` |
-| `spinifex_external_mode` | `pool` | `pool` \| `nat` external networking |
-
-`dev-reset.yml` automatically captures `region`, `az`, `external_mode`,
-pool range, gateway, prefix-len, nat gateway_ip from the existing
-`/etc/spinifex/spinifex.toml` before teardown and replays them into
-`init`. Use `-e` to override.
-
-## Leak catalog
-
-`roles/teardown/README.md` tracks every known state source. When teardown
-misses something, add it there and in `roles/teardown/tasks/main.yml`.

-# teardown — Leak Catalog
-
-Every task in this role corresponds to a known state source that survived a
-previous reset. When the operator reports "reset didn't clean X", add a new
-task and a new row here citing the symptom.
-
-## Initial catalog (from reset-dev-env.sh + reset-dev-env.md target)
-
-| State source | Cleaned by | Symptom if leaked |
-|---|---|---|
-| `spinifex.target` active | `systemctl stop` | Services keep running, file locks held |
-| `spinifex-*` units in failed state | `systemctl reset-failed 'spinifex-*'` | `systemctl status` shows red units, next start refuses |
-| Spinifex processes (spx, nats, predastore, etc.) | `pkill` pattern + wait loop | Stale listeners on 4222/8443/9999, start fails with "address in use" |
-| QEMU VMs | `pkill qemu-system-*` + wait loop | Zombie VMs hold tap interfaces and viperblock state |
-| `/etc/spinifex/` | `file: state=absent` | Stale TOML, stale CA, service users can't read fresh config |
-| `/var/lib/spinifex/` | `file: state=absent` | Stale WAL, stale volumes, viperblock mounts fail |
-| `/var/log/spinifex/` | `file: state=absent` | Logrotate confusion, permission drift after user changes |
-| `/run/spinifex/` | `file: state=absent` | Stale sockets, pidfiles from prior systemd run |
-| `$HOME/spinifex/` (legacy) | `file: state=absent` | Old dev-mode state shadowing new install |
-| OVS bridges (all) | `ovs-vsctl del-br` loop | `br-int` populated with stale ports → `ovn-controller` commit loop |
-| OVS `external_ids` | `ovs-vsctl clear Open_vSwitch .` | Stale chassis entries in SBDB |
-| `/var/lib/ovn/ovnnb_db.db`, `ovnsb_db.db` | `file: state=absent` | "OVNSB commit failed, force recompute" loop after reset |
-| `veth-wan-br` / `veth-wan-ovs` | `ip link delete` | Pair left dangling after setup-ovn.sh re-run |
-| `spx-ext-*` macvlan interfaces | `ip link delete` loop | Stale macvlan on WAN NIC, packet duplication |
-| Spinifex CA in trust store | remove + `update-ca-certificates` | TLS clients trust old CA, new cert fails verification |
-
-## Not cleaned by default (opt-in)
-
-| State source | Flag | Why opt-in |
-|---|---|---|
-| `~/.ssh/spinifex-key*` | `-e spinifex_wipe_ssh_keys=true` | Operator may want key to persist across resets |
-| `~/.aws/credentials` spinifex profile | `-e spinifex_wipe_aws_creds=true` | `spx admin init --force` rewrites this block anyway; wipe only on demand |
-
-## Known traps
-
-- **`pgrep -f` self-match.** A literal pattern that matches the pattern
-  string itself causes `pgrep -f` to match our own shell. Mitigation:
-  bracket trick (`[b]in/spx` matches `bin/spx` but not `[b]in/spx`).
-- **Log followers / ansible wrapper false positives.** `journalctl -f
-  _SYSTEMD_UNIT=spinifex-*` and ansible's own module shell matches the
-  service-name patterns in their cmdlines. Mitigation:
-  `spinifex_process_exclude` filter drops `journalctl|ansible|/bin/sh|pgrep|pkill|tail -[fF]`.
-- **SIGTERM survivors.** `spx service spinifex start` (and potentially
-  other service-supervisor processes) ignore or delay SIGTERM. Mitigation:
-  kill task escalates SIGTERM → SIGKILL after 5s.
-
-## Adding a new entry
-
-1. Add a task to `tasks/main.yml` in the right section (services / state-dirs /
-   ovn / ovs / netlink / trust / user-owned).
-2. Prefix the task `name:` with the state class (e.g. `netlink:`, `ovn:`).
-3. Add a row to the catalog above — symptom is what the operator described.
-4. If the leak class is general (e.g. "any interface matching spx-*"),
-   generalise the task; do not pattern-match on a single instance name.
