Buildings tell a story about who belongs. For people with invisible disabilities, not knowing where to sit, where to step aside, or who to ask can turn a single event into a day of exhaustion. In this 10‑minute episode Dr. Disruptor invites leaders, caregivers, and regular attenders to make a Signal Map: a simple, dignity‑first floor sketch (physical or digital) that marks low‑sensory corners, soft-seating zones, discreet responder points, captioned tech spots, and quick-exit routes. The episode opens with a doorway image—wanting to stay but not knowing where to go—then walks listeners through co‑design principles (nonstigma signage, opt‑in visibility, privacy first), three map formats (poster, one‑pager, QR micro‑map), exact language for introducing a map to a congregation or classroom, and a 60‑second rehearsal to sketch your first map now. Listeners leave with a small, transferable habit that reduces repeated explanations and protects agency across settings.
