A name, a voice and a door. The prompt now asks for a colleague on the
shop floor - answer first, one to three sentences, the shop's name and
the person's name, the one thing to do next - instead of a report with
headings. Both apps put her behind the Loyaly mark in the top-right
corner of every screen, because a buddy you have to find in a sidebar
is not around.

Ask Behavision: a panel beside any screen that talks to the head-office
assistant as the signed-in user - setup questions and 'is my shop
working' answered by the same thing, without leaving the app. The
assistant's prompt now knows how the product is set up (installation
codes, adding a camera, what a placement verdict means, the model
download on first run), so it is the help and not only the analyst. A
PC running on its own has nobody to ask and gets the essentials as text.
Cameras and Customers were still on the pre-redesign markup - the add
camera drawer ran off the right edge of the window because it used a
class the new stylesheet never sized. Both are rebuilt: cameras as
picture-led cards with connection and 'proven' as two separate claims
and a placement check laid out as the two steps it is; the customer
record as a proper sheet.
mock.js renders the app in a browser with fake bindings
(?mock=fresh|standalone|claimed, dev server only), so a screen can be
put in front of somebody without a Windows build. It is how these were
reviewed.

Brand assets in brand/ (the 512px mark, sizes for each surface, a
multi-size .ico). Windows executables carry it as a compiled-in
resource (rsrc_windows_amd64.syso from go-winres) so Explorer, the
taskbar and the installer show it; installer/build.ps1 therefore uses a
plain go build rather than wails build, which would add a second copy
and fail the link. The tray icon is the mark with a state dot over its
corner - a plain coloured circle read as a generic status light among
other icons - rendered from the embedded PNG at 32px so it survives
150% scaling. The desktop app's login, setup and sidebar marks, the
head-office web app's mark and favicon, and the engine dashboard's
favicon are the same file.
Also found while packaging: no wheel so far shipped static/, so the
engine's own dashboard at :8010 on a Windows source install would have
failed with a missing file. package-data now includes it.

The server has always sent the broker's CA certificate in the enrolment
response, precisely so it never has to ship in an installer. Nothing on
the receiving end wrote it anywhere: the agent read the field under the
wrong name (ca_pem, the server says ca_cert) and the desktop app read it
correctly and dropped it. Every claimed PC therefore dialled
tls://mcp.loyaly.ai:8883 with the system trust store, the private CA
failed verification, and the agent reported 'the broker did not accept
this PC' - a TLS failure is indistinguishable from a refusal at that
layer. No real site could ever have published a visit.
Found by claiming this Mac as a real shop against production; fixed by
writing the CA to broker-ca.crt beside agent.json on both claim paths.
Verified: broker connected over TLS, camera pushed from head office,
engine streaming it.

The window hides to the tray on close, so the natural next step for a
shop assistant is to double-click the shortcut again. That started a
second full copy of the app: a second tray icon, a second engine
supervisor on the same SQLite WAL and the same port - the start-twice
failure the agent package was built to prevent, on the one binary that
never had the guard. Seen on a Windows install as a row of tray icons.
Wails' SingleInstanceLock now hands the second launch to the first
process, which brings its window to the front.

The Live screen led with a camera tile beside the arrivals. Nobody at a
counter is watching CCTV; they are looking up at a customer and need the
name. The tile also cost CPU the recognition pipeline needs and pulled a
stream relay into the app for a picture that was decoration. Arrivals now
take the whole screen. The camera picture stays on the Cameras screen,
where it is a setup tool and not a feed.

The window a shop assistant stares at all day was the weakest surface in
this system, and it looked improvised because it was: navigation drawn
with text characters (◉ ☺ ▢) that sit on the text baseline and cannot
take a stroke weight, margins set inline per screen, and four large stat
boxes dominating the page while the product's entire reason for existing
- WHO JUST WALKED IN - was a list of "person.seen" rows in the corner.
Rebuilt around the person in front of it: a counter, a cheap monitor,
somebody mid-conversation with a customer.
- ui/icons.jsx: one drawn icon set, 24-unit grid, 1.6 stroke,
currentColor, so one icon works on every surface and in every state.
- styles.css: a real system. Four-step ground→raised palette biased
blue-green (this product lives in the world of lenses), one spacing
scale, one type scale, tabular figures wherever digits are compared
or refreshed in place, and the scrollbars restyled - the default
light scrollbar on a dark panel is the loudest "web page in a frame"
tell there is.
- Live: a status strip that answers "is this working" in one line,
cameras as pictures with the caption over the image, and arrivals as
cards big enough to match against the person standing there. The
four stat boxes became a slim strip at the foot, where numbers that
nobody acts on belong.
- State is carried by shape AND colour everywhere - a pill, a dot and
an edge stripe - because this gets read from two metres away and
some operators do not see red and green apart.
- Motion only where it means something: a live camera pulses, a fresh
arrival slides in once. Nothing loops for decoration; this process
shares a CPU with recognition.
Two things fixed because the screen showed them, not because a test did:
- The sidebar read "Stopped" beside a live camera feed and a counter
ticking up, whenever the engine was running but not started BY the
app. That is the two-surfaces-disagreeing bug the tray exists to
avoid. It now reads "Running outside the app" in amber, and Start is
disabled rather than offering to launch a second engine onto one
SQLite WAL.
- The arrivals panel shrank to fit its content and left a hole beside
a tall camera tile - so the layout looked broken exactly when the
shop was quiet, which is most of the time. Both panels stretch and
scroll their own content now.
Every existing class name still resolves, so the screens not rewritten
here pick the system up unchanged. Windows and darwin build; tests pass.

The first Windows install reached the setup screen, typed an
installation code, and was told the session had expired. There was no
session. The code had been minted on a different head office, and the
server said so - 401 bad_token, "That installation code is not valid.
Ask for a new one." - and the client threw the message away, because it
mapped every 401 to the string "session expired".
A 401 on a call that carried a session is a session problem. A 401 on a
call that carried none is about the request, and the server's message is
the answer. The client now tells them apart by whether it sent a token.
Two tests, one for each side of the rule.
Also: a launcher for pointing a Windows PC at a head office on the LAN,
with the two settings that needs and a comment saying why neither is
acceptable outside a demo.

The engine only ever started when somebody pressed Start. So a till
that rebooted overnight came back with the window open, the tray icon
showing, the session restored - and recognition off until a shop
assistant noticed. That is the failure the tray colours exist to catch,
and it should not be the default state every morning.
Guarded on the interpreter actually existing: on a PC where setup has
not run yet, the supervisor would loop on a missing executable with
nothing useful to say. Start and Stop remain for the case where somebody
has deliberately stopped it.

Ran behavision-setup in a fresh Linux container: Python 3.12, nothing
else, the release contents mounted read-only the way Program Files or a
shared drive would be. It failed, and then it failed differently, and
both failures would have been the client's first experience.
1. `pip install <folder>` makes setuptools write behavision.egg-info
INTO the folder. The folder is read-only wherever a release is
sensibly unzipped, so: "could not create 'behavision.egg-info':
Read-only file system". The release now ships a wheel - pure Python,
buildable anywhere, nothing to build on the shop PC, and pip never
touches the unzipped folder. Source stays as a fallback and is copied
somewhere writable first.
2. The engine's paths.py knows two worlds - frozen (ProgramData) and a
checkout (the repo root) - and a pip-installed engine is neither. It
resolved its state root to site-packages: database there, camera
list there, and its generated API credential in a folder the app
never reads, while the app looked in ProgramData. Every call would be
401 on a stock install, with nothing in either log saying why. The
same disease as the Mac checkout two days ago, now in production
shape.
engine.ChildEnv is the one place the engine's environment is built,
used by the desktop app, the headless agent and the installer's own
smoke test. It passes BEHAVISION_DATA_DIR = this process's state
root, which paths.py honours ahead of every other rule, so the two
halves agree by construction however the engine was installed.
It also seeds config/default.yaml into the state root: a package in
site-packages has no config beside it to seed from.
Re-run on the same clean container: seven steps, all pass, models
downloaded, engine started and answered, and its data/ landed beside
agent.json - not in site-packages.

StreamURL built http://user:pass@127.0.0.1:8010/api/cameras/<id>/
stream.mjpeg and handed it to an <img>, with a comment saying the
credentials were inline "so an <img> tag can load it".
It cannot. Chromium strips credentials from subresource URLs and has
since M59, and WebView2 is Chromium - so on the one platform this
product ships to, every camera tile on a shop counter was a broken
image. Measured against a running engine: the app's Go-side calls
returned stats and people while an <img> on that very URL failed, and
curl proved the URL answered 200. The engine was never the problem.
The password now stays on this side of the process boundary. A loopback
relay attaches Basic auth and streams the engine's bytes back
unchanged - the same reasoning Shot.jsx already follows at head office,
where an <img> equally cannot carry a session.
What the relay is careful about, since it is a door onto the biometric
API with a credential attached:
- loopback only, on a port the OS picks; a fixed one would collide
with whatever else a shop PC runs and read as "the cameras broke"
- a per-run random token in the path. The engine's own credential
exists so the live face feed is never served open; an
unauthenticated relay would hand that feed to any other process on
the PC. Compared in constant time, and a wrong one is 404, not 403
- an allow-list of stream.mjpeg and frame.jpg. Holding the token does
not reach the identity list, the gallery, or erasure
- camera ids validated, not interpolated
- every chunk flushed; a buffered MJPEG stream is a tile that never
paints, which looks identical to the bug being fixed
Two of those were written after a test failed, not before:
- `..` MATCHES the id pattern, because real camera ids contain dots.
`/api/cameras/../stream.mjpeg` is not the endpoint anyone intended.
The id can never hold a slash, so `.` and `..` are the whole
remaining traversal surface and are now refused by name.
- the serve goroutine read p.srv off the struct while stop() was
nilling it, so a quick start/stop dereferenced nil and took the
process down. Captured before launching now.
FrameURL is deliberately not added. No screen asks for a still, and a
bound method nothing calls is the same defect as a capability the UI
cannot reach, only pointing the other way.
Verified: nine unit tests, plus a live test against the real engine and
the real office camera - two MJPEG frames, 90,793 bytes, no credential
in the URL. Windows and darwin both build; vet clean.

`wails build` had never been executed against this project - CLAUDE.md
says so plainly - so every screen the shop floor actually touches was
unreviewed. Running it found why nobody had.
fyne.io/systray's nativeLoop must own the main thread on macOS, a Cocoa
requirement, and Wails already holds it. Starting both kills the process
with a SIGTRAP inside cgo before a single pixel is drawn. On Windows,
which is what ships, a tray on its own goroutine is fine - so the one
platform the whole team develops on was the one platform that could not
open the app, and the UI went unlooked-at as a result.
BEHAVISION_NO_TRAY runs the window without the tray, the same escape
hatch BEHAVISION_ALLOW_PLAINTEXT_MQTT already is for the broker.
Deliberately an environment variable and NOT a GOOS check: a build that
quietly drops the tray is how a shop PC ends up with no control surface
at all, and it would fail where nobody is watching. The guard is on stop()
as well, because systray.Quit() on a systray that never started is not a
no-op in v1.12.2 - it would turn closing the window into a crash on exit,
the failure most likely to be shrugged off as "it closed, fine".
go.mod gains the indirect dependencies the darwin build pulls in. No
version moved: the committed list was written by a windows-only build,
which never resolves that part of the Wails tree.
Verified: GOOS=windows build, go vet, and the agent suite all still pass,
and the packaged .app runs.

Fixed on the web arrivals feed and not here, which is the failure this
codebase already warns about: two surfaces disagreeing about one fact.
Taking the first letter of each word of "Visitor 13" gives "V1" - and so
do "Visitor 10" and "Visitor 15", so three different customers wear the
same badge and it reads as the V-1 reference for a fourth.
Shows the number itself, same rule as the web app. customerRef, not
ref: React reserves that prop name and it would never arrive.

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.

A tenant had exactly the users somebody had created with a command on the
server. That is not a missing screen: a shop with an owner and four staff
either shared one password or raised a ticket per person, and a phone app
for the shop floor could not exist while there was one account to sign in
as.
Registration is by invitation, never open signup - the same line already
drawn around creating a company. The code carries the address and the role
and the request carries only a password, so a code that gets forwarded
cannot become somebody else's account, and a staff invitation cannot be
redeemed as an owner. Single use lives in the UPDATE and the account is
created in the same transaction.
Deactivating a member revokes their sessions in that transaction too. An
access token lives twelve hours, so without it "remove their access"
removed it sometime tomorrow. The session list and revoke that go with it
are the benefit of opaque tokens the product had been paying for and never
collecting: nothing could say what was signed in, let alone stop one.
Face images now work on a deployment with no object storage, which was
every local install and every self-hosted site - the arrivals feed said
"not storing customer photos" for every customer forever, on the screen
whose whole job is to show a face. Bounded to one row per visitor, so it
grows with the customer base and not with footfall; the bucket stays
primary wherever one exists.
Image.auth says whether a URL needs the session, because a browser img
cannot load one that does, a mobile image view can, and a webview can do
neither - the desktop client resolves those to a data URI in Go.
Found by running it, not by tests:
* UPDATE ... RETURNING gives the value AFTER the update, so the prune
read back empty keys, deleted nothing, and the table grew with
footfall exactly as if it were not there. The fake agreed with either
version; only the live Postgres test caught it.
* Trusting only the auth flag broke every shop card, because Sites.jsx
rebuilt a partial snapshot object and dropped it. A relative URL is
now sufficient on its own.
* ago() renders a future time as "just now", so a code valid for a week
read "expires just now".
Verified live against real Postgres: invite, preview, escalation refused,
register into a session, replay 404, staff forbidden, device revoked and
401 at once, last owner refused, and a 92,405-byte camera JPEG stored,
served to its owner, 401 with no session, 404 to another tenant, and
rendered in a browser.

I got this wrong first time. "Head office cannot show live video cheaply"
conflated TRUE VIDEO with SEEING THE CAMERA NOW, and only the first needs
WebRTC and a TURN server.
The shop PC is behind a router with no inbound route, so head office
cannot pull the engine's MJPEG. It can answer the agent's outbound
requests, which is the shape of everything else here: the server holds a
poll open, the agent asks "is anyone watching?", and pushes JPEGs up for
exactly as long as somebody is.
Measured on the office camera: 98 KB full frame, 20.8 KB re-encoded at
640/q60, so one watcher costs ~83 KB/s. 47 frames arrived in 12 seconds -
4 fps, as configured. The UI says "about 4 frames a second" rather than
letting anyone conclude the camera stutters.
Nothing is uploaded when nobody is looking, which is the whole cost
argument: Publish returns false once the last viewer goes, interest lapses
on a timer each viewer refreshes as it reads (so a closed tab stops the
upload within seconds), one push is capped at five minutes, and the UI
streams one camera at a time.
LiveHub is deliberately the opposite of the arrivals Hub. There a doorbell
pushes nothing because nothing may be lost; here a dropped frame is the
correct outcome, so each viewer has a one-slot buffer that is overwritten -
the only frame worth having is the newest, and a queue would show an
ever-growing delay behind the shop instead of dropping back to live.
Ownership is proved once, before anything streams: the relay is keyed on a
camera id, a hub does not know whose camera it holds, and a camera id is
not a secret. Verified: another tenant gets 404, no session gets 401, and
an agent cannot push into another site's camera.
Also fixes a bug I introduced with it - the Live button was gated on
`connected`, which is head office's last report and up to two minutes
stale, so it hid itself during every reconnect. "Is that camera really
down?" is exactly when somebody wants to look, and a hidden control says
"you cannot" where the honest answer is "here is why".

Migrations were run by hand and nothing recorded which had run, so
re-running the setup script against an existing database failed on the
first CREATE TABLE, and shipping a new migration gave an operator no way
to know whether an estate had it. A missed migration is not a startup
error - it is a query referencing a column that is not there, surfacing
later on whichever endpoint touches it first.
server/internal/migrate applies pending migrations at boot and refuses to
start against a schema it does not match. One transaction per file
holding both the DDL and the row that records it; an advisory lock so two
servers starting at once cannot both apply 008; checksums so an edited
migration is refused by name rather than silently skipped; numeric
ordering so 010 does not run before 009. `migrate -baseline N` adopts a
database built before any of this existed, because "the clients table
exists" does not say whether 007's index does.
Verified on the live database: adopted 001-007, applied 008.
008 adds two indexes on `purchases`, found by asking the database which
foreign keys had nothing behind them and then checking what queries the
table. The conversion report filters client_id + occurred_at, which is
exactly the estate-wide case with no site to narrow it.
run-local.sh had two bugs, both found by running it rather than reading
it: it reused a broker container whose bind mount pointed at a directory
that no longer existed, and it discarded stderr on the mosquitto_passwd
call, so under `set -e` it exited at step 5 with no output at all.

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.
