Exact-capacity test of the simultaneous 13-triple link of the stabilizer-fixed pair {4,5} on all 754 frozen type-4 signature/e_45 targets
No ProgressThe complete labelled {4,5} link was tested across the entire frozen type-4 frontier. Exact aggregation produced 431 cells. All 754 targets survived with independently checked positive witnesses, so the relaxation has zero pruning value. This is scoped campaign progress, not a 54-cover, exclusion certificate, or exact determination.
Strategy and discriminatorcomplete fixed-pair link relaxation
Aggregate all 2717 residual blocks by five root intersections, exact {4,5} incidence, and the complete labelled 13-bit {4,5,z} link vector; solve every frozen target and independently expand positive cell counts to literal blocks.
Hypothesis: At least one of the 754 previously skeleton-feasible type-4 signature/e_45 targets has no exact-capacity residual witness once all 13 triples containing {4,5} must be covered simultaneously.
Test: Run 754 incremental exact integer-feasibility checks over a capacity-preserving 431-cell quotient and require literal-expandable positive witnesses or a separately certified negative result.
RationaleThe all-positive witness map is complete for the declared frontier, independently reconstructed at literal-block level, mutation-tested, and byte-identically regenerated. It decisively falsifies the route's pruning hypothesis without extrapolating beyond its necessary-relaxation scope.
Claims requiring scrutiny- The complete fixed-pair-link feature census contains exactly 431 capacity-preserving cells: 156 nonpair cells and 275 singleton {4,5}-block cells.
- Every one of the 754 frozen type-4 signature/e_45 targets admits a 49-distinct-block residual witness satisfying the five source-indexed margins, exact {4,5} count, and all 13 {4,5,z} coverage obligations.

Independent checkercheckers/check_type4_complete_pair_link_gate_v1.py independently enumerates all residual literal blocks without Z3, reconstructs the 431 cells, expands each witness to 49 distinct blocks, and checks all source margins, pair counts, and 13 link obligations.

Cross-domain transfers tested- Terra exact-capacity advisory -> prediction of a 431-cell complete-link quotient -> Sol independently reconstructed exactly 431 cells, then found that all 754 targets survived.
Established facts- The complete-link quotient has exactly 431 cells.

Ruled out in this epoch- Use the complete labelled link of the single stabilizer-fixed pair {4,5} to eliminate a frozen type-4 signature or e_45 target.

Continuation checkpointObjective: Determine whether explicit pair-excess conservation materially improves proof search on the type-4 branch.
First action: Create the matched base/extended 25000-conflict protocol and an independent formula-equivalence checker.
Stop condition: Stop or redirect if neither run is decisive and the extended encoding fails to reduce propagation cost by at least 20 percent.
Next moves- Freeze a matched base/extended type-4 CNF protocol exposing all pair-excess variables and weighted-degree-two conservation.
- Independently reconstruct formula equivalence before measuring solver behavior.
- At 25000 conflicts, continue only for a certified decisive status or at least 20 percent lower propagation cost.
