The first stage run built v4 on igneum-seed-1 in 60 min 49 s and then failed on `igneumd --version | head -1` under
pipefail, because the devnet-v4 igneumd prints its version and exits 1. The post-build steps now write to files and
test them; the tarball is unpacked once per src.stamp so a rerun is incremental; `stage-v4.sh <seed> resume` reruns
the build script on the tree already on the VM and then waits and installs.

Windows combined package 0.2.0 (proto-cuda/windows-app): v4 exes from target-integration, peers = seed then Mac,
fresh appdir devnet-v4, one miner and one worker per card with --identities 8, --evm-address (PAYOUT_EVM or derived
per vendor from the PC name), voting on (VOTE=0 opts out), --prepare-packs for the hot swap with --exit-on-seed-change
as the fallback, --yes on the node, STATUS regex tolerant of the v4 now= segment, version in the dashboard header.
Mac app 0.2.0 (packaging/mac): v4 binaries, Metal worker rebuilt for macOS 11, data folder devnet-v4, EVM payout,
identities in one process, synced= flag honoured. Seed (infra/seed-nodes): stage-v4.sh builds v4 on the VM as a
niced, memory-capped transient service and installs a disabled igneumd-v4 unit with a fresh data dir; switch-v4.sh
swaps the units (--back reverses); health.sh reports active-v4. Runbook: docs/plans/cutover-2026-10-04.md.

igneum-seed-1 (Hetzner cx23, fsn1, 188.245.5.161:26611): built on the VM in 1,530 s, synced to the live devnet
(12,204 blocks, same sink as the live node) through a non-mining relay igneumd on the Mac (the live node's addPeer
RPC is refused in safe mode); the live node and the Windows PC learned the seed's address by peer exchange and dialled
it. seeds.txt written. Hetzner prices corrected to USD (pricing API currency) in the plans, READMEs and scripts;
current-generation types per location (cx23 EU, cpx22 sin, cpx21 US) in the cloud-devnet config.

infra/cloud-devnet: hcloud (doctl variant) create, builder-VM provision from a git-archive source tarball,
systemd units for igneumd --devnet-suffix with a sparse --addpeer mesh and a CPU trickle miner per node,
stdlib wRPC client, experiments (latency, partition, hop, collect, observer hookup), README with the command
sequence and the Hetzner API prices of 3 Oct 2026.
infra/gpu-bench: RunPod image recipes (CUDA 12.8, ROCm), bundle, run.sh (vectors gate, 10-min raw, sweep,
inline shortcut ratio, nvcc/NVRTC/OpenCL recompile timings, results row, intake upload), bench-log template.
infra/seed-nodes: create-seed (persistent IPv4, firewall), provision on the VM, health check, addPeer from the
Mac over grpcurl, seeds.txt; igneum-seed-1 created at 188.245.5.161 (Hetzner cx23, fsn1).
