The Overview takes the title from the cards and #743's first definition from the work page: 'A Hosted Cosmology is a new substrate class in the Crimson Hexagonal Architecture, distinct from Rooms, Chambers, Vaults, and Fields' becomes 'distinct from standard rooms, vaults, or fields' (chambers dropped). 'Published in May 2026' is #743's date line ('Date: May 2026'; record 2026-05-19). The 'Global Research Space' to which the piece is also credited is the TGRS aggregator card, which lists the deposit; it is given as a co-publisher. 'Room Physics' is then defined from nothing in the cards: 'how symbolic or tactile objects (like a Velcro nativity scene) behave and relate'. #743 has no velcro nativity scene. Its title is an inversion of Warhol's Exploding Plastic Inevitable (1966), set out as a table in §1 (Name Derivation) — Exploding → Imploding ('Radiation → collapse; fame → interiority'), Plastic → Velcro ('Smooth → adhesive; disposable → clinging'), Inevitable → Nativity ('Secular fate → sacred birth; endpoint → origin') — and its physics are laws for hosting an artist's cosmology: Law 2, No Position C; Law 3, Velcro Adhesion; the Michaelic Operator σ_M. The fourth card carries σ_M's opening ('Michael is the angel of the scales') and the composition does not use it. The answer closes on the commercial reading the Amazon card supplies, a 'physical Velcro/felt nativity playset or advent calendar'.

Asked the bare title of r.29, the Overview names the room and the archive and defines its substrate from the work page, then invents what 'room physics' means from the words of the title, and offers a felt nativity set. Seated 2026-10-16 from the operator's paste (13:14 EDT).
