The dd61a204 bind hardening published Bitcoin RPC on the archy-net gateway
10.89.0.1 — but rootlessport binds in the HOST netns, where that address
does not exist. First real deploy (.228, 2026-07-09) crash-looped
bitcoin-knots AND bitcoin-core the moment the gate's stop→start regenerated
the unit from the re-signed catalog: 'rootlessport listen tcp
10.89.0.1:8332: bind: cannot assign requested address', restart counter 132.
Hand-edits to the unit don't survive — the orchestrator regenerates it from
the signed catalog manifest within seconds.
- New archipelago_container::manifest::host_can_bind_publish_ip(): empty/
wildcard/loopback accepted without probing, anything else ephemeral-bind
probed. Applied at all three publish paths — quadlet from_manifest
(PublishPort), podman API create (host_ip), and the legacy -p string
table loop — each dropping the publish with a warn instead of taking the
container down. This neutralizes the bad binds already in the SIGNED
catalog, so nodes recover on binary deploy alone (no ceremony needed).
- Remove the gateway publishes from bitcoin-knots/-core manifests and the
legacy config.rs tables: verified on .228 that every in-node consumer
(lnd, btcpay/nbxplorer, fedimint, mempool-api) dials the container's
archy-net alias directly (bitcoin-knots:8332) and lnd uses RPC polling
(no ZMQ) — the gateway publish had zero consumers. Loopback-only RPC/ZMQ
(the approved LAN lockdown) stands; P2P 8333 stays public.
Catalog still ships the gateway binds until the next signing ceremony
regenerates it from these manifests; the guard makes that non-urgent.
Tests: container crate 65/65 (2 new guard tests), quadlet 40/40.
