Materialized and independently classified the complete depth-four pair-surplus ownership bucket whose processed internal weighted graph is a unit perfect matching.
No ProgressA complete 4.08% internal-edge slice of the exact depth-four pair-surplus profile layer was materialized: 17337 raw S11 tables give 2548 canonical profiles representing 18667722645 labelled prefixes, and every deletion parent lies among 296 keys in the frozen depth-three ledger. A different Burnside/polynomial checker, seven mutations, a byte-identical rerun, and a cap boundary control passed. This is structural infrastructure only; 30 <= C(15,6,3) <= 31 is unchanged.
Strategy and discriminatorcanonical pair-surplus prefix augmentation
Enumerate exact external-vector multiplicity tables for one complete S4 internal-edge orbit, canonicalize under its stabilizer, map every record to all canonical depth-three deletion parents, and validate completeness with a separate Burnside/polynomial encoding.
Hypothesis: The complete unit-perfect-matching depth-four bucket has at most 10000 canonical profiles, can be materialized within 120 seconds and 1 GiB, and every deletion parent belongs to the frozen exact 1775-key depth-three ledger.
Test: Explicitly materialize the whole bucket, require a separate stabilizer-Burnside polynomial DP and ordered-sequence DP to reproduce aggregate totals, validate every record and parent, reject seven mutations, rerun byte-identically, and fail closed at a cap one below the exact count.
RationaleThe producer exhausts the exact-row-sum multiset universe for the frozen internal orbit, while the checker proves the required orbit count without depending on that enumeration and then validates every retained record. The evidence is decisive for the stated bucket and has no quantified implication outside it.
Claims requiring scrutiny- The complete degree-feasible depth-four pair-surplus bucket with internal weighted graph equal up to S4 to a unit perfect matching has exactly 2548 canonical profiles.
- That bucket contains exactly 17337 S11 multiset tables and represents exactly 18667722645 labelled prefixes across the three internal matchings.
- All deletion parents of all 2548 profiles occur in exactly 296 keys of the frozen 1775-key depth-three ledger; 225 keys own at least one child under minimum-parent ownership.
- The maintained covering range remains 30 <= C(15,6,3) <= 31.

Independent checkercheckers/check_pair_surplus_depth4_matching_bucket_v1.py uses stabilizer Burnside polynomial DP and ordered-sequence DP to establish aggregate completeness without enumerating the producer's multiset stream, then independently reconstructs every record, orbit weight, deletion parent, owner, and digest.

Open leads- Checkpointed complete depth-four ownership ledger
The exact total is 62437 and the complete 2548-profile calibration passed with an estimated approximately 96 MB stream; completing ownership is the next prerequisite for safe later decomposition. · Implement internal-edge-orbit checkpoint/restart, verify a two-orbit resumed stream byte-for-byte, then submit the full producer/checker to the lab. · high · open - Materially changed exact-degree-12 constructive witness search
A 30-block witness remains the shortest terminal certificate, while previous six-representative incidence timing runs produced only UNKNOWN and cannot justify repetition. · Predeclare and compare one new encoding-level mechanism against the frozen incidence baseline on identical branches before any scale-up. · normal · open - Surplus-profile to root-link compatibility bridge
A complete surplus graph fixes all pair multiplicities, potentially shrinking root-link and residual-cover constraints more strongly than either decomposition alone. · After a complete-H pilot exists, compile one hash-owned H class into root-link compatibility equations and measure candidate/proof size against the direct completion encoding. · low · open
Continuation checkpointObjective: Qualify checkpointed full depth-four profile/parent materialization.
First action: Refactor scripts/pair_surplus_depth4_matching_bucket_v1.py into deterministic internal-edge-orbit chunks and run a two-orbit interruption/resume comparison.
Stop condition: Redirect on restart nondeterminism, count mismatch, foreign parent, duplicate key, checker disagreement, or measured resource projection beyond the declared lab tranche.
Next moves- Refactor the producer into checkpointable canonical internal-edge-orbit chunks and run a two-orbit restart/resume byte-stability control.
- Submit full 62437-profile materialization and its independent parent checker to the checkpointed lab with a 100000-record cap, 1 GiB limit, immutable epoch-102/105 inputs, and measured continuation thresholds.
- Forecast later complete-H and proof-certificate volumes before generating cover-completion SAT leaves.
- Keep a materially changed exact-degree-12 constructive witness route in the resolution portfolio; do not repeat the prior six-branch timing calibration without new encoding evidence.
