ARC-1 — Ambient Residue Collectibles: MVP Specification for Field-First AR Discovery, Single-Take Transfer, and Afterfield Decay

Abstract ARC-1 specifies the minimum viable architecture for a field-first augmented-reality collectible system in which user-placed hidden entities are discovered through haptic and chromatic pre-reveal signals, revealed in situ, transferred once into a personal collection layer, and reduced over time to a non-interactive fading afterfield. Rather than relying on map-first spawn logic or centrally generated collectible visibility, ARC-1 defines a user-placed residue architecture in which presence is first sensed, then revealed, then transferred out of the environment upon discovery. The MVP validates a complete interaction loop: hidden placement, haptic detection, chromatic bleed, local reveal, single-take transfer, disappearance from world state, and post-expiry residue. ARC-1 is positioned as a lightweight ambient alternative to centrally spawned, map-visible, infinitely reproducible collectible logic, and as a playful applied branch of the Ambient Era Canon.
