SlipCuff

LSC via Wrist-Mounted Interface (aka "Slipcuff" or "Phaseband")

Core Concept:

The device generates a short-range spatial compression field, collapsing the distance between your current location and a calibrated target point. You're not teleporting — you're stepping through compressed space.

In-World Features & Functions:

✅ Wrist-Integrated Control

• Looks like a sleek bracer or disk with a crystalline interface or dynamic hologram.
• UI might include target icons, resonance maps, or “step zones.”
• Includes safety protocols like environmental scan, bio-readiness check, and cooldown limiters.

✅ How It Feels In-Use:

• A moment of compression around the chest or ears — like falling into yourself and being pulled forward.
• Light bends briefly. Sound stutters. You step, and the world shifts.

✅ Range & Limitations:

• Limited to pre-calibrated points within ~1 km radius (urban) or ~5–10 km (open terrain).
• Must have line-of-sight data or preloaded geospatial imprint.
• Cannot pass through certain alloys, shielding fields, or compressed-matter zones.

✅ Failure Modes (for drama):

• Spatial echo (arrive slightly out-of-phase or in a parallel layer for a moment).
• Backlash sync (user appears but leaves gear behind — or vice versa).
• In rare cases: slip fracture (user re-materializes halfway through a wall or object).

Technobabble Justification:

“The phaseband generates a temporary spatial compression corridor, momentarily folding local topography to reduce transit space. Instead of traveling across a surface, you're stepping through a micro-spatial envelope—like snapping the pages of a book together.”
