Records the networking decision behind Phase 6b's arrival notifications so it
doesn't get re-derived later.
ntfy stays LAN-only: identity -> ntfy is a container-to-container call that never
reaches OPNsense, and remote delivery rides a WireGuard split tunnel routing only
the smart-home VLAN. No DMZ, no port forward, no certificates, no inter-VLAN rule.
Both alternatives were weighed and rejected, with reasons recorded:
- DMZ + port forward buys only "notifications without the VPN connected," at the
cost of a public listener, TLS upkeep, and mandatory ntfy auth — an exposed
topic leaks "the house is empty right now".
- DMZ + NAT reflection does avoid a new inter-VLAN rule (the smart-home VLAN's
existing outbound-WAN allow already covers traffic to your own public IP), but
makes a purely internal path depend on the ISP and external DNS being up, so
two devices metres apart stop talking during a WAN outage. CGNAT breaks it
outright, and the rule it avoids was the safe direction anyway.
New §2.1 covers the split tunnel itself, including the trap that motivated it:
AllowedIPs must be the actual VLAN prefix, never 192.168.0.0/16, which collides
with typical café/hotel LANs and breaks the phone's connectivity there. Plus
always-on VPN yes / lockdown no, and no DNS= so queries aren't pulled home.
The household uses no Apple devices, which removes the only forcing function for
exposure (ntfy's iOS app needs APNs and therefore an upstream relay). Open
decision #37 closes as a household decision; the Apple case is kept as a
footnote in case that ever changes.

Phase 19: trash-calendar (Kennelbach ICS -> CalDAV) and transit (GTFS
departures + OpenTripPlanner-backed voice route planning, slow walking
speed assumed). Phase 20: Tapo camera integration via identity's new
Frigate face-recognition presence signal, and chores, a presence/
calendar-driven household task nudger ("I don't care who does it, as
long as it gets done") with a passive fairness tally, litter culprit
attribution, and per-person chore_exempt/chore_reminder_style settings
on identity.
Also: the HA integrations + hardware-monitoring catalogs, Music
Assistant wiring, docs/network-integration.md (OPNsense VLAN
segmentation, no WAN port-forwards), the ESPHome BLE-proxy firmware,
and RuView CSI-presence integration (github.com/ruvnet/ruview) with
household automations for sleep/distress/concurrent-vitals/bathroom-
occupancy — all flagged with their real unverified assumptions and
open decisions. Fixed two real port collisions surfaced while wiring
this in (OTP vs. zigbee2mqtt on 8080, Music Assistant vs. pantry-vision
on 8095).
