One household. A Leash for everyone.
Give each family member capped, disposable card numbers for the things they use — without handing out your real card, and without watching over their shoulder. Caps and Snips are visible to the people they affect.
Capped member Leashes
Issue a teen a $15-cap Leash for their music app. It cannot bill above the cap — no surprise charges, no shared real card.
Transparency, not surveillance
Every holder sees their own caps and Snips. There is no covert monitoring — the kill switch must never become a tool of control (§10.5).
An independent path stays open
A controlled member always keeps an independent, private financial path. Tether never becomes the single chokepoint another person controls (§10.8).
One household, many lines
Each person and each service rides its own Leash, all drawing from the household's real funding source — which no merchant ever sees.
Leashes are demonstrated with disposable demo cards; real funded cards ship once an issuing partner clears the Build-Spec §7.5 gate. Shared-Leash transparency and the independent-path guardrail are design obligations, not options.
