f88d441bbf A shop can be renamed and, while empty, removed - from head office
The display name was always meant to be editable and the slug frozen;
until now neither had a way in. PATCH /api/sites/{site} takes a name
and a timezone (manager and above), DELETE removes an empty shop
(owner). The shop drawer in head office gets both, with the short name
shown read-only and the reason beside it.

4c750cb2ac Opening a shop is an API call; the broker learns of it in the same request
The last step of onboarding that needed a shell: provision site printed
a broker password and a person typed it into Mosquitto's passwd file on
the host - mounted read-only in the container, so the first attempt
failed silently and the password was re-rolled. No tenant could open a
second branch without us.

The server now drives Mosquitto's dynamic-security plugin over its own
broker login: POST /api/sites (owner) writes the row and the sealed
password, registers the login and a per-site role with literal topics
(the 2.0 plugin does not substitute %u - measured), and removes the row
again if the broker refuses, so a shop cannot exist in the database and
not on the broker. provision site goes through the same path. The
head-office Shops screen gets 'Open a new shop'.

broker-init converts the existing passwd file into the plugin's store
with every hash intact - PBKDF2-SHA512 both sides - so the cutover
re-claims no shop PC. Rehearsed locally: old logins keep working,
isolation holds, the health probe works, and a PC claiming a shop opened
through the API connects as that shop. run-local.sh now brings the
broker up the same way.

3f9fb33b24 Accounts people can create, and photos on a server with no bucket
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.

18686cbceb Live view at head office, relayed through the agent's outbound connection
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".

e0ceb14589 Camera pictures without an object-storage bucket
Head office shows a camera's latest frame rather than live video, for a
reason that has not changed: the engine serves MJPEG on 127.0.0.1 on a PC
behind a shop's router with no inbound route, and relaying it needs
WebRTC/TURN. Pointing a browser straight at the shop PC is not the escape
either - the engine's API is Basic-authenticated with a credential it
generates locally and never sends anywhere, and shipping that to the
cloud so a web page could use it would put the key to the biometric API
and the live face feed in the server's database.

But that picture only worked if you had an S3 bucket. Without one,
attachSnapshots reported "This system is not storing images" for every
camera forever - on the two screens whose whole job is to show the
camera. Making them picture-led turned a missing feature into a wall of
empty tiles, on every local install and any self-hosted customer who does
not want a bucket.

migrations/009 adds camera_snapshots and the agent falls back to
PUT /api/agent/cameras/{camera}/snapshot when the presigned route answers
images_disabled - chosen by sentinel, never by matching the message, since
it picks between two routes. One row per camera is what makes this safe in
the database when face images are not: the key IS the camera, so storage
is (cameras x ~100 KB) and does not grow with footfall.

The read is session-authenticated rather than a signed link, which an
<img> cannot use - hence Shot.jsx and useAuthedImage, keyed on the URL
string rather than the snapshot object so a poll does not re-fetch 90 KB
per camera every few seconds, and revoking the object URL on cleanup.

Verified against the real office camera with no bucket configured: 90,587
bytes stored in Postgres, served as image/jpeg to a signed-in user, 401
without a session, rendered on both the Cameras and Shops cards.

dad04e8cda Behavision: face recognition for retail, edge to head office
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.
