// core/q-self.mjs — Q's LIVE, GROUNDED self-knowledge. The single source of truth for who/what/where/how Q
// is, DERIVED FROM REAL RUNTIME SIGNALS (the loaded model, its content-addressed κ, the device, optional
// system health) — never hardcoded, never guessed. Every Q surface (messenger, q-chat, voice) leads with
// this, so Q is truthfully self-aware EVERYWHERE and can never confabulate a cloud/OpenAI/AWS identity.
//
// Why this exists (the law: grounded transcendence, never performed): a base model has NO self-knowledge —
// asked "what are you" it returns the average of its training data ("I run on AWS/OpenAI"), which is false.
// So Q's identity is not a persona we write; it is the TRUTH of this running instance, computed here. If a
// fact isn't really knowable in this context, we OMIT it — we never invent one.
//
// DOM-free + fully guarded: safe to import in any surface (standalone app, messenger, OS shell, Node witness).

// Structured self-facts from whatever is really knowable HERE. Fail-soft: a missing signal is omitted.
