Close the def/dev supervision gap at the source: every node brought up gets watched, and every supervisor enumerates the registry. - bin/ensure-node-supervision.sh (new, idempotent): appends the NODES.md row (netvm-names port, honors CDP_PORT_OVERRIDE so it never fights provision's picker) and installs/enables chromebox-watchdog-<node>.timer. --all heals drift (registry + /etc/netvm identities). Template verified byte-identical to the installed def unit. - netvm-node-up.sh: calls ensure (non-fatal) at the end. Provision and the onboarding pipeline reach it transitively. - relay-health-check.sh, cdp-latency-check.sh: registry-driven watched_nodes() + LIB_ONLY guards (were hardcoded 4 nodes). - tests/test_node_supervision.py (6): row add/idempotent/override, timer render, node-up wiring, both watched_nodes(). - CHROMEBOX-RUNBOOK.md: setup-fed supervision section. Pairs with the registry-driven relay/chromebox watchdogs: new rows are picked up on the next run with no per-node code edits.
