Installation was six scripts each carrying its own copy of the container host's
IP, three that had to agree on IDENTITY_TOKEN, and every service URL typed by
hand with a port in it. Any one could be wrong, and the symptom was always the
same and always late: an image that boots fine and then can't reach something,
found after a 40-minute build and a reboot.
Two properties fix that class of bug:
- Nothing is written twice. No script in tools/ contains an IP, port or token.
- Anything derivable is derived. You give the subnet prefix once and one last
octet per host; every address and service URL is computed from those.
THE TWINNED PAIR. container_host.ip_last_octet 12 and llm_host 13 mean the
container host's OLLAMA_HOST *is* http://<prefix>.13:11434 — computed in the
same build, not typed into two files and kept in sync. Move the LLM host to .21
and the container host's Ollama URL follows; change the subnet and both halves
move along with every kiosk's URLs. Neither image can be built pointing at an
address the other isn't using. Both carry the same SMARTHOME_PAIR_ID (a hash of
the config's meaning, not its bytes) so two USB sticks can be checked against
each other later.
validate-config.py runs before every build and refuses to start on an error, so
a mistake costs seconds not an hour. It catches duplicate ports (including the
music_assistant/pantry_vision 8095 clash that Compose can't see because MA runs
network_mode:host — open decision #31), both hosts on one address, duplicate
hostnames across kiosks and audio endpoints, placeholder tokens (checked before
the length check, so padding "changeme" to 32 chars doesn't pass), a private key
pasted where the public one goes, and a kiosk pointed at a disabled service.
build-all.sh is the normal entry point — the images are a set that has to agree
with itself, so building one is the exception. It builds the core pair, every
kiosk, and every audio endpoint including both architectures (amd64 live-build
ISO and arm64 rpi-image-gen img are different toolchains, not one image).
The two new host ISOs install unattended with everything burnt in, including
service env files generated from derived values — which permanently removes the
class of bug that had chores.env shipping IDENTITY_URL=http://127.0.0.1:8097.
setup-container-host.sh and setup-llm-host.sh now read every config value as
${VAR:-default} so the images configure them without editing.
That also makes every ISO a credential: Wi-Fi PSK, tokens, MQTT and HA
credentials are readable by anyone holding the stick. .gitignore covers the
filled-in CoreSystemConfig.json and build-output/.
Tested: 43 config validation/derivation checks and 44 builder checks against the
real code paths with only `lb` stubbed — every generated env file, preseed,
network config, first-boot unit and build stamp is verified, including that a
port collision refuses the build before writing anything. No ISO has been built;
`lb build` needs live-build, root and a long fetch. tools/README.md says so.

identity/ (Phase 6, rewritten from the original Node-RED sketch): a
person <-> BLE-identifier registry built directly as a Python service.
Solves multi-phone (multiple identifiers per person), anti-spoofing
(only allowlisted IRK-resolved/fixed-tag entities are ever accepted as
registration candidates, never a raw or randomized MAC), device-less
people (a grandmother without a smartphone gets a no_device registration
plus a hand-operated home/away toggle, reported as "unknown" rather than
a false "away"), and anonymous guests (POST /register/guest, no name
needed). Every person gets an automatic profile picture from their most
recent registration photo. /presence also reports a best-effort room per
person as groundwork for an eventual floor-plan view (not built).
Registration is single-utterance voice ("register me as <name>") or a
touchscreen form; ambiguous/conflicting candidates never auto-commit.
hosts/door-panel/ (Phase 18, new host): structurally kitchen-display's
twin - one Sway workspace, one Chromium kiosk window - defaulting to
identity's weather+clothing/who's-home/groceries-running-low dashboard,
with voice registration as its actual purpose (mic on by default, unlike
every other host's opt-in).
hosts/kitchen-display/: adds opt-in voice satellite and a "Show
registration" screen pointed at identity's register.html, reusing the
same camera-equipped-endpoint registration flow.
pantry-vision/: adds GET /shopping-list (Grocy's own volatile/missing
products, reshaped) for the door panel's "running low" section.
setup-container-host.sh: wires ENABLE_IDENTITY (identity + identity-web,
published like pantry-vision since kiosk browsers call it directly, plus
a persistent SQLite/photos volume unlike pantry-vision's stateless
design) and fixes the HA_URL example to the host's real LAN IP (HA runs
network_mode: host, unreachable by container name - the same situation
Node-RED's own config already documents).
docs/: Phase 6 rewritten, Phase 18 added, hardware/software/guardrail/
open-decision entries throughout project-plan.md and README.md.
components.md gains RuView presence nodes (one per room), fixed BLE tags,
and 2 spare webcams, with the price estimate updated to match.
Nothing here has been run against real hardware, a real HA instance, or
real Private BLE Device entities - TRUSTED_ENTITY_PREFIXES above all
needs checking against a live instance before registration finds
anything. See identity/README.md and hosts/door-panel/README.md for the
itemized verification lists.
