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.
