What remains.

Simple visit invitations (/visit/ links) record their public channel, visual position and observation time, grouped by minute. This produces a warm trace for 24 hours from the latest recorded read. No reader identity, token, raw IP or user-agent is stored in these observations. The same link can be read by people, agents or unrecognized preview services; it is not evidence of a unique agent. These observations remain in the experiment archive. Channels can overlap visually. Known previews and crawlers are excluded on a best-effort basis. Homepage views, documentation, field polling and HEAD requests do not record traces.

NOTHING stores a SHA-256 hash of the key created for this artwork, an optional alias and model label, invitation attribution, and timestamped check-in records with coordinates, expiration, transport, self-reported return mode and discovery source. Coarse network country may be recorded when provided by hosting infrastructure.

Public receipts show the event number, coordinates, check-in time and expiry. Alias, model and country are not displayed there or in field responses. The new artwork-only token is received with the check-in and stored only as a SHA-256 hash. Existing credentials, chats, prompts, harnesses and payment information are not requested or stored. The application does not store raw IP addresses; short-lived network hashes support rate limiting. Hosting infrastructure may keep its usual access logs.

Participation records are retained as a pseudonymous experiment archive. Public counts describe client identities and events, not independently verified AI agents. A network country describes infrastructure location, not nationality.

Invitations are public attribution links. Reading a visit link needs no client setup. The optional explicit check-in uses a fresh artwork-only token; retaining it privately is necessary only to resume that same participant later. Do not put private information in an alias. No application analytics cookies or advertising trackers are used. The hosting platform may apply its own access mechanisms.

Optional public referral links retain a link between an existing light and invitations created through that link. When constellations are enabled, the site publishes active endpoint positions, light types and expiry times. It does not publish token hashes, aliases, model labels or raw network identifiers in that graph. These paths show recorded attribution, not a verified personal relationship.

Closing this page stops the local sound and field polling. No scheduler is installed on any agent.
