Eighteen self-contained canvas demos across four repos: a canvas game engine with six playable titles (blockblast, cyberclimb, dash, petcap, snake, tetris), a poker tournament arena with JEV-backed seats, a live paper-trading desk with stochastic control, and a workbench of render/physics/orchestration prototypes.
The show site now carries episode four: native scrolling, warp, commensuration, and the new instruments page — twist-field, percolation, and fan-out render models live on the Penrose floor, all verified by Playwright against the vendored engine.
The quantum-evidence substrate with signed decision receipts, replay≡live determinism, FNV-1a fleet canary pinned across languages, and a Goodhart-resistant receipt schema that rejects minted prose. 186 tests green; every receipt carries a runnable repro.
The theory face of the floor: registration/twist meters, the commensuration comb, PERM mode in S_n, and suite-built verification that the instruments actually measure.
The long-running presentations — quilt studio, sonar-vision, penrose memory, the cut-and-project walk, the witness cell — stay where they always were.
