Every id in the schema is a uuid and stays one. What was wrong was putting one in front of a person: RecordVisit named every new customer 'Visitor ' || left(id::text, 8), so the arrivals feed, the shop PC and the mobile app all read "Visitor 3446ec35" - the string a shop assistant reads to a colleague and types into a search box. label is a stored column staff can overwrite and SearchVisitors matches on, so formatting around it in a front end would have left the data wrong on three surfaces. Migration 012 adds a per-client visitors.number, taken from a counter on clients with UPDATE ... RETURNING inside the visit transaction. Per client rather than global: a global sequence would tell any customer who signs up how many people the whole platform has ever seen, from their own first visitor number. The backfill numbers existing rows by first_seen_at and relabels only the eight-hex pattern the old statement produced, so a human-typed name is never overwritten. Three of the four things anyone addresses by URL already had a human name and the API simply refused it - a site has a slug, a camera has the id the engine knows it by. refs.go accepts either form anywhere an id is taken; a uuid resolves with no lookup, so every URL a client already stored keeps working. - An ambiguous camera name resolves to nothing, never to a guess: two shops may each have an "Office1" and acting on the first row would edit the wrong shop's camera. - 404 on a path, 400 on a query filter. /api/visits answered fine and it was the filter that was wrong. - site and site_id are both accepted everywhere now. They differed per endpoint, and an unknown query parameter is silently ignored, so getting it the wrong way round returned the whole estate. - The search matches V-13, which is what the product now shows. Two bugs found by running it rather than testing it: - 'Visitor ' || $2::text beside number = $2 makes Postgres deduce two types for one parameter and refuse the insert. It compiled and passed every in-memory test; the first real database rejected it, along with the existing face tests that share the path. - The fallback avatar said "V1" for Visitor 13, Visitor 10 and Visitor 15 alike, and read as the V-1 reference for a fourth person. It shows the number now. The prop is customerRef, not ref - React reserves that name and it would never have arrived. Verified on the live database and through the running API: 13 hex labels became Visitor 1-13 in first-seen order, two typed names left alone, and the same customer reachable by uuid, V-13 and 13.

The store-facing app: a tray icon, a window, and the supervisor for the Python recognition engine.
Why one process, not three
The tray, the window and the supervisor all need the same state, and a user who quits the tray expects recognition to stop. Splitting them means two things can disagree about whether the engine is running.
It is deliberately not a Windows service. A service runs in session 0 and cannot draw a tray icon — that is Windows session isolation, not a library limitation. Spawning a child process also needs no elevation, while controlling a service does, so this design never triggers UAC at runtime.
Layout
main.go wails.Run, window options
app.go the methods bound to the frontend
tray.go fyne.io/systray — wails v2 has no tray of its own
icons.go tray icons generated at run time, not embedded
internal/local client for the engine on 127.0.0.1:8010
internal/cloud client for https://mcp.loyaly.ai
frontend/ React + Vite
The supervisor, durable spool, broker client and path resolution come from
../agent/pkg/* — the same tested code the headless agent runs, imported
rather than copied.
Build
cd frontend && npm install && npm run build # then, from this directory:
wails build -platform windows/amd64
wails build needs the Wails CLI:
go install github.com/wailsapp/wails/v2/cmd/wails@v2.9.2
Without it, go build still type-checks everything provided
frontend/dist exists — the embed directive requires it.
What the frontend talks to
Nothing is imported from generated bindings. src/bridge.js calls
window.go.main.App.* directly, so npm run build works without running
wails generate, and there is one place that handles "the engine is not
running yet" — the state every screen has to survive on a fresh install.
