Both found by operating the stack rather than writing it: the local
processes were OOM-killed and bringing them back hit two gaps.
The headless agent had no way to be claimed at all. Bootstrap lived only
in desktop/internal/cloud, so the one configuration the agent binary
exists for - a back-office PC with no window - could only be onboarded by
hand-editing agent.json, which is the state the desktop's Setup screen was
built to end. `behavision-agent claim <code>` closes it; the CLI joins its
arguments because the code is printed in groups for reading aloud and an
operator pasting it will paste the spaces too.
Second: after the site's broker password was re-rolled, mosquitto logged
"not authorised" while the agent logged "timed out". Those need opposite
actions - re-link this PC, or go and look at the network - and paho's
SetConnectRetry collapses them, because it retries internally and the
connect token never completes. describeStall asks whether a TCP socket
opens at all, and says what is known rather than guessing at a reason the
broker never gives.
Verified end to end: minted a code from the platform as the owner,
claimed with the new command, broker connected, and the shop went to
online: true with 1/1 cameras on w600k_r50.
Also corrects this machine's memory in CLAUDE.md from 16 GB to 8 GB. It
feeds the model-fallback reasoning, and the local gallery already holds
17 embeddings tagged w600k_mbf beside 19 tagged w600k_r50 - the fallback
has silently fired before.

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.
