Status and Honesty

Status and Honesty

Wick was built on Amazon's simulators, which the hackathon allows, and then run on a real Fire TV Stick 4K Select. This page says exactly what is real and what stands in for something.

What is real, and what is simulated

	In this submission
Television	The Vega app on a real Fire TV Stick 4K Select (Vega OS), as the demo video shows, and on the Vega Virtual Device; the Fire OS build on the Android TV emulator. A browser version runs the same cards and break rules, for quick testing only.
Doorbell	Ring's Developer Playground, behind Ring's real API. It sends no webhooks and has no chime, so demo homes use a clearly labelled stand-in doorbell with made-up visitors (FL-027).
Alexa+	A simulated surface that signs in with OAuth and calls the real MCP server (FL-001). The Alexa+ add-on surface is partner-only.
Household	A demo home with six weeks of simulated history, marked as simulated everywhere.
Films	Blender Foundation's open films.

Everything between those ends is real and deployed: the AWS stack, the MCP server, the agents and models, the Guardian, accounts and pairing.

Not seen on real hardware

• A Ring doorbell.
• A spoken "Alexa, pause".

Legibility at three metres and sound on a real panel have not been measured, only seen on the Fire TV Stick 4K Select.

Measured against the deployed stack

Measurement	Result
Doorbell to door card	2.3 s median, on the stand-in doorbell (Ring's own webhook hop is extra)
Launch to fully drawn, Vega	722 ms mean, 632 to 807 ms, over 10 cold starts on the Vega Virtual Device
Memory on her home screen, Vega	64 MiB PSS, steady over a minute, on the Vega Virtual Device
MCP server's own work	18 ms p95
MCP call on an open connection	230 to 241 ms p95, against Alexa+'s 500 ms target

New connections are slower because App Runner closes idle connections (issue 47).

Known limits

• No long-lived credential reaches the television, but the Vega simulator cannot keep a secret on disk. It is therefore only ever paired to demo homes, and the repository says so (INV-1 in AGENTS.md).
• Amazon's Content Personalization is told what she watches, as the platform asks. Nothing on a television shows its effect, so Wick does not claim one.
• The Guardian reads English. Text in another script is not cleared, except the names of the household's own people. It cannot catch what its lexicon does not list.
• Lambda concurrency in the AWS account is limited to 10, so the Ring webhook reservation cannot be set until AWS raises the quota. The webhook has its own throttle meanwhile.
• Wick is not a medical device and makes no clinical claims.
