The first launch was a code box with a link under it, then an empty
Live screen with 'No cameras' in amber in a far corner, then a form
asking for an IP address, and for the first few minutes of all of it
the engine silently downloading 275 MB with nothing on screen but a
stopped-looking status. Walked in a browser with the new mock; nobody
who was not an installer would have got through it.
Now: a welcome that asks the one question a shop owner can answer -
managed from a head office, or on this PC only - with each path in a
sentence; a Getting Started checklist on Live that reads its three steps
from the engine and ticks them itself (recognition ready, camera added
and connected, camera proven by a walk-past), with the one button for
the next step, and that disappears the moment somebody is recognised;
and the model download reported as a percentage in the tray, the
sidebar and the checklist, parsed by the supervisor from the engine's
own progress lines.

Five components that ship as one product:
- behavision/ the recognition engine. RTSP ingest, YuNet detection, IoU
tracking, ArcFace embeddings, a FAISS/SQLite gallery, and a
FastAPI dashboard. Identity is decided once per TRACK from an
average of at least three embeddings, never per frame.
- agent/ the Go edge agent: supervises the engine, holds a durable
spool, and drains it to MQTT. Nothing is acked before the
broker confirms.
- desktop/ the shop PC application (Wails + React + tray).
- server/ the cloud API, MQTT consumer, reports and assistant.
- web/ platform.loyaly.ai, the head-office app, embedded in the
server binary.
The gallery stores 512-float embeddings and timestamps - no images unless
`app.store_faces` is switched on. Those embeddings are biometric personal
data under GDPR and India's DPDP: template inversion reconstructs a
recognisable face from an ArcFace vector, so data/behavision.db is treated
as a biometric database and DELETE /api/visitors/{id} is a real erasure.
CLAUDE.md carries the reasoning behind every non-obvious decision here,
including the ones that were measured and the ones that were wrong first.
