The GREEN multi-node regression bed that proves the DB-consumer gate: substrate/control on one node, postgres+redis providers and baserow+letta consumers on another, each consumer getting its own credential and its own mesh-named database across the overlay. Requires the mesh-control provider-seal-key fix and the mesh-catalog db-name fix. Includes a general lab capability: a machine 'disk' field sizing the VM root disk (a broad install exhausts the pool default and the host fails mid-apply with 'no space left on device'). The bed sets 60GiB. Claude-Session: https://claude.ai/code/session_01LrgweAeERJYBg88c5cKDzF

# The DB-consumer chain a single node cannot host, proved across two machines.
|
||
#
|
||
# The app-postgres provider and the mesh's own substrate store both want host port 5432, so they
|
||
# cannot share a machine — the collision that blocked this chain single-node. Here the substrate
|
||
# (store, broker, control) lives on `anchor` and NOTHING else; `laptop` runs the whole chain —
|
||
# postgres and redis PROVIDERS plus the baserow and letta CONSUMERS that require them. Both
|
||
# machines sit on one shared segment and enrol into the one mesh; only enrolment crosses to anchor,
|
||
# over the underlay both machines already share. Provider and consumers are co-located on laptop, so
|
||
# no cross-node module comms and no overlay are needed — and the 5432-vs-substrate conflict is gone
|
||
# because the substrate store is on the OTHER node.
