Multi-agent review (5 confirmed) + Codex found real issues in the rework:
- [P1 security] Shared `shelly` ACL had readwrite +/rpc, so a compromised
device could inject Switch.Set into ANY other device's <prefix>/rpc. Now
read-only on +/rpc (receive own commands) + write only homeos/rpc (reply).
Broker-verified: a shelly publish to victim/rpc is denied; laravel's is not.
- [P2 security] `+` wildcard reaches reserved homeos/ring namespaces → bogus
device. Ingest now rejects RESERVED_PREFIXES (homeos/ring/$SYS).
- [P2 security] Unbounded auto-onboarding = DB-exhaustion DoS. Added a device
cap (homeos.mqtt.max_devices, default 250).
- [P2 correctness] Every Shelly `input` became a phantom window contact (wall
switches shown as windows, possibly inverted). `input` is now a generic
sensor; the user PROMOTES specific inputs to window/door contacts on the
device page (invert-aware), stored in config->input_roles and applied in the
ingest — this is the "assign contacts" flow the user asked for.
- [P3 ux] Motion pill read `active`; producer writes `on`. Now reads both.
- [P1 migrations] Dedup computed survivor keys once; 3+ duplicates could
collide on unique(device_id,key). Re-query per duplicate (ring + mqtt_prefix).
+9 tests (reserved prefix, cap, input generic/promoted/inverted, demo echo).
Live-verified: input published → onboarded as input → assigned window contact
via UI → appears on Fenster page, persists across messages. Suite 57 green,
12/12 tabs clean.

Addresses "I have to configure MQTT per device; HA just works":
- Shared device account `shelly` (one credential every Shelly uses) with a
SCOPED ACL (status/events/online/rpc for any prefix; cannot touch homeos/,
ring/ or $SYS). gen-passwd seeds it from MQTT_SHELLY_PASSWORD.
- Auto-onboarding: IngestShellyMessage creates the device on the first
recognizable component (sys/wifi/cloud noise ignored), so pointing a Shelly
at the broker is all it takes — no manual "Zuweisen". Partial unique index on
config->>'mqtt_prefix' + race-safe create (merge-dedup migration).
- Settings → Geräte-MQTT card: server, username, reveal/copy password + steps
(config/homeos.php, MQTT_DEVICE_HOST). Discovery "Zuweisen" now upserts by
prefix (names/rooms an already-onboarded device, no duplicate) and no longer
forces per-device creds.
- Per-device credentials kept as opt-in hardening: a "generate" button on the
device page (pattern %u ACL retained).
Live-verified: publishing as `shelly` to a new prefix auto-creates the device
with switch+power state; a sys topic creates nothing. Suite 46 green, 12/12
tabs clean.
