Mind Simulation — Emergent Observer Mode

A phase-1 mean-field implementation of the reflexive loop z → a=Z(t) → M → C → Ω → return, per Y_THEORY_EMERGENT_OBSERVER_MODE_PATCH_2026-09-03. Recursively nested field levels are displayed on declared ring-torus scaffolds; each node supplies one live main-loop phase while its tube lane is fixed by the renderer. That one-live-angle display does not itself earn an S¹×S¹ phase topology. Click a glowing (drillable) node to descend one scale; the collective mode shown is always this level's own ρeiΘ, never invented from a level you have not visited. The g_return slider is the decisive control from OBSERVER_MODE_SIMULATOR_SPEC.md: at 0, a persistent coherent whole may be earned, but no observer can be earned because Ω is not returned. Above 0, retained comparison is fed back into this level's own phase update; observerhood is earned only after that return has actually changed the field. The coherence threshold and persistence window are explicit simulator-level detectors, not source constants.

The loaded fractal-observer-teaching-profile-v2 is a finite, replayable teaching projection. At every recursive field, coupling, delay, and tick interval are derived from that field's own base rate: K=ωrK, τ=rτ/ω, and Δttick=rtick/ω. Unique path addresses and the resolved network fingerprint below identify the exact topology and materialized operator being viewed. The ratios, counts, and finite depth are explicit implementation choices; the recursive identity and observer-return relations are the source-traced structure.
