Four deterministic strict exact-degree ejection-chain arms of lengths 4, 5, 6, and 7 from the verified defect-10 seed, followed by a complete pre-acceptance proposal audit.
No ProgressThe four-arm variable-length ejection-chain discriminator completed 32768 proposals. Although 32750 strict exact-degree replacements were generated, none improved defect 10 before acceptance. Independently checked proposed minima were 13, 17, 18, and 22. No cover or exclusion was obtained.

Strategy and discriminatorvariable-length exact-degree ejection chains
Target an uncovered triple, select outgoing blocks by dynamic unique-coverage-loss tournaments, preserve their complete point-incidence multiset, and close the incoming family by randomized-tie bipartite Havel-Hakimi construction.
Hypothesis: At least one of four 8192-proposal arms produces a directly checked 54-block family with fewer than ten uncovered triples.
Test: Audit all legal proposed replacements before acceptance and advance only if an independently checked proposed family has defect below 10.
RationaleThe producer, repeated regeneration, and direct family checkers agree on the saved minima and invariants. Because the search is sampled and non-exhaustive, it supports closure only of protocol v1, not any mathematical exclusion.
Claims requiring scrutiny- Every recorded accepted arm best is byte-identical to the defect-10 input seed.
- The accepted global best has 54 distinct blocks, point degrees 18^15, and covers exactly 445 triples.
- The deterministic audit reported no defect-improving proposal among its 32750 legal sampled replacements.
- The saved best-proposed families have independently checked defects 13, 17, 18, and 22 for lengths 4, 5, 6, and 7.
Evidence and scope- Producer experiment 20260810-065309-818bda completed 32768 proposals.
- Independent accepted-best check 20260810-065428-4014c5 passed with four rejected mutations.
- Regeneration experiment 20260810-065509-799008 reproduced all trace and best files.
- Proposal audit 20260810-065848-66cd0e found zero improving sampled proposals.
- Direct proposed-minimum check 20260810-065920-8569cc passed.
- Repeated audit 20260810-065939-302891 reproduced the identical stdout hash.

Computational experiments- .proof-experiments/20260810-065309-818bda: producer; 32768 proposals, zero accepted moves, best defect 10.
- .proof-experiments/20260810-065428-4014c5: independent accepted-best check; direct coverage agreement and four mutations rejected.
- .proof-experiments/20260810-065509-799008: fresh regeneration; all traces and best files reproduced.
- .proof-experiments/20260810-065848-66cd0e: complete pre-acceptance proposal audit; zero improving sampled proposals.
- .proof-experiments/20260810-065920-8569cc: independent direct checks of four proposed minima.
- .proof-experiments/20260810-065939-302891: repeated proposal audit with identical output hash.
Independent checkercheck_degree18_ejection_chain_v1.py directly checks accepted best families, and check_degree18_ejection_proposal_audit_v1.py independently recomputes each saved proposed minimum using tuple counters and a 455-bit mask. Full proposal-stream enumeration was deterministically regenerated but not independently reimplemented.

Cross-domain transfers tested- Exact bipartite degree realization -> predicted cheap variable-length closure -> 32750 of 32768 proposals closed successfully.
- Uncovered-triple-guided local search -> predicted coverage improvement -> every sampled proposal instead increased defect, with best increase from 10 to 13.
- Pre-acceptance auditing -> predicted separation of proposal and annealing failures -> showed proposal geometry itself was already inadequate.
Established facts- Protocol v1's accepted best is the hash-bound defect-10 input seed.
Independent tuple/bit-mask checks and byte-identical regeneration · The four recorded protocol-v1 arms only · computed - The deterministic proposal audit's saved per-arm minima have defects 13, 17, 18, and 22.

Ruled out in this epoch- Scale protocol v1 solely by increasing its cutoff, changing its seed, or raising its acceptance temperature.
The saved outgoing tournament, Havel-Hakimi closure, energy, and four arm definitions · No sampled legal proposal improved defect before acceptance; the best proposed defect was 13. · artifacts/degree18-ejection-chain-20260810/proposal-audit.json and proposal-audit-independent-check.json · Materially new coverage-aware proposal geometry that independently verifies defect below 10
Open leads- Proof-replayed layer-five successor
Its 288-cell predecessor passed pruning and complete proof-replay gates. · After explicit owner approval, freeze and run the 12-by-256 selector-union protocol. · high · open - Proof-preserving globally complete encoding improvement
It remains unblocked and can affect the exact target rather than one sampled basin. · Independently reconstruct one materially changed canonical branch encoding and compare at a matched cap. · normal · open - Coverage-aware exact closure
Degree closure is cheap, but outgoing/incoming choices must explicitly preserve singleton-covered triples. · Before another search, solve a 256-proposal matched pilot whose closure objective lexicographically minimizes lost singleton triples and then defect. · low · open
Continuation checkpointObjective: Resolve the authorization gate for the proof-replayed layer-five successor; otherwise improve a globally complete proof encoding.
First action: Present the exact 3072-cell layer-five scope and predecessor receipt for explicit owner approval; do not dispatch without it.
Stop condition: Stop on absent approval, proof/formula reconstruction disagreement, or failure of the matched global encoding improvement gate.
Next moves- Do not increase protocol-v1 cutoff, change only its seed, or raise its acceptance temperature.
- Obtain explicit owner approval before dispatching the 12-by-256 proof-replayed layer-five successor.
- Absent approval, test one materially new proof-preserving globally complete encoding with independent formula reconstruction and a matched improvement gate.
- Reopen constructive chains only with materially new coverage-aware proposal geometry and a directly checked defect below 10.
