Ilker ManapandClaude Opus 5.5 4d9284ce9f Find each node's management interface, and lift the agent's memlock limit
The agent's defaults said eth0 before normalize looked for the interface
holding the management address, so it never looked: a node on ens3 or
bond0 had NCCL and Gloo bootstrap over an interface it does not have. It
is now found, with eth0 only as the last resort.

The agent unit sets LimitMEMLOCK=infinity. RDMA pins what it registers,
and under systemd's 8 MB default an engine without the capability that
lets root ignore the limit fails its first collective over InfiniBand.

Ilker ManapandClaude Opus 5 555e4678cb Ship the systemd units, and stop the plan lying about what is done
CI / test (push) Successful in 1m16s
Phase 3 had a block duplicated into itself, including an unchecked
'EndpointSource becomes dynamic' sitting directly under the checked line
saying it was wired. Several phase 5 items had shipped without being ticked.

The units were only ever on the machines and in a scratch directory, which
makes them undocumented operational knowledge rather than part of the project.
KillMode=process in particular is not obvious and not optional: without it
systemd takes the engines down with the agent, turning a thirty-second upgrade
into a model reload on every node.
