Verified on lin001 over SSH on 2026-08-20, read-only:
- Port 502 is bound to 10.0.0.17, not 0.0.0.0, so unauthenticated Modbus is
not internet-reachable at the Docker level. This was an open risk in §3 and
an unchecked item in §15; it is now a confirmation. openplc-runtime also
publishes 8443 (the Runtime web UI) on the same private address, which the
spec did not mention.
- openplc-runtime is not the only published port on the host: caddy, wireguard,
mosquitto and chirpstack-gateway-bridge all publish on 0.0.0.0. The
no-published-ports rule still applies in full to what we build, but the
"one deliberate exception" framing was wrong and invited over-reading.
- Port 22 is open to the internet. Added to §15 as an open item for the same
NSG review.
- 21 containers running, not 22; no stopped containers.
- /datadisk is 46% used with InfluxDB at 55 GB, up from 43%/52 GB. Recorded
the growth rate so it can be budgeted for.
CLAUDE.md restates two of these rules and is updated to match.

Build spec and host brief carried in from C:\Claude and WRPS/02-env; the
plant model (equipment, tags, alarm bitmask, enums, unit conversions) is
derived from WRPS/04-plc/register-map.csv, WRPS/05-scada/modbus/scada-points.csv
and WRPS-CTL-003.
