- TAA-1 Appliance Node: washers, dryers, specialty machines, chargers
- TAA-1 Room Node: tool rooms, storage closets, maker spaces

Design goals
1. Time-bound access rather than identity-heavy policing
2. Local-first operation with optional network features
3. Low installation complexity
4. Clear safety profile
5. Low-cost pilot path and stronger institutional variant

Pilot tiers
Tier A: single lock + keypad + timer
Tier B: keypad/RFID + relay + door sensing
Tier C: multi-node controller + rotating tokens + supervisor dashboard

Recommended go-to-market
- Phase 1: DIY / open-source builder kit
- Phase 2: Property-manager pilot kit
- Phase 3: Institutional room controller

Primary value proposition
A fair-access layer for shared equipment that reduces theft, queue jumping, and conflict without surveillance-heavy monitoring.

Important engineering notes
- Use electric strikes / bolts for rigid locking
- Keep mains switching isolated and enclosed
- Separate safety functions from convenience functions
- Provide manual override and documented recovery procedure
