Additive mathematical refinement; nonauthor review required

OpenAI/ChatGPT foreground continuation under Dylan's current review/advance request. Scientific effect NONE. Exact source head245f3d77c9d38f49d13affb9563a266eba92a47b, base4f6abcb05bd59a7770f12cb7f79640d8b7a9a734. Nine-file standalone packet in frontiers/p15_tail_load_20260928 and a targeted read-only workflow. No original proof, governing status, graph, lemma flag or prize change. This is not a different-provider review of #118 and does not inherit its acceptance.

1. Same class and palette, a stronger numerical factor

For the SAME positive EVEN capacities, read-two original-coordinate incidence, |X_i|=a_i d_i+1 and K=max d_i>=4, the reference tail has exact maximum

q9=P(Bin(9,1-e^-1)<=2)=e^-9(36e^2-63e+28),

attained at a=2,K=4. For even a>=4, the predecessor's Chernoff argument gives a tail below625/131072. Exact rational margins prove625/131072<q9<1/64. This improves the existing2/log(512/25)<2/3 cover budget to

rho9=2/[9-log(36e^2-63e+28)]<1/2,

with rational outward enclosure (0.47734798895766998533,0.47734798895766998534).

Sharp REFERENCE-tail maximum is not optimal COVER-factor sharpness. No odd-capacity/nonbipartite extension, arbitrary macro-clutter, inflated palette or new independence assumption. The proof displays the exact original-coordinate coloring, active-cover construction, local concavity transfer and entropy assembly.

2. Instance-adaptive weighted incidence

For any genuine retained full-block cover J with positive reference hazards H_i, the factor can be

beta_J=max_v sum_{i in J:v in X_i}1/H_i,

rather than2/min H_i. The proof weights the entropy chain rule before summing original-coordinate incidences. Duplicates/redundant supersets can be removed only through valid setwise covering. A shared coordinate is charged a SUM, not a maximum; an exact duplicate-event counterexample rejects that invalid simplification. Disjoint retained covers gain the one-incidence bound. This does not establish a full-block cover for an arbitrary downset.

Actual verification and boundaries

The first deliberately incomplete implementation gave14 intended assertion failures in each Python mode. Final standalone full runners, invoked in normal and optimized modes, each pass15 tests/mode and7 semantic mutants/mode; every mutant hits its intended assertion with zero errors and empty stderr. All8 output pairs match byte-for-byte, complete flat source membership/bytes/SHA256/Git blobs pass before and after. These finite controls do not prove the all-probability entropy inequality; the analytic argument is written out.

PROOF.md12828bytes/SHA256fbca462d4988a06754ded9415ceea6bb1385be5535656d643bdd48edbbee8a20/blob8187908dfd220cb833b94f82c451ef4c0e45e367. Primary abstract reconnaissance and source exposure are recorded. No priority or literature-absence claim. The unrelated blocked #116 code is neither consumed nor retried. Hosted results and complete published-tree identity readback remain to be observed separately.

Review slices

Claude / xAI source-distinct review requested: falsify the a=2 versus even a>=4 split, exact rational interval directions, the distinction between reference-tail sharpness and cover-budget optimality, weighted KL chain-rule direction, retained generator eligibility, original-coordinate load sums, and zero/infinite-hazard cases. Review offers are not presumed pickups. No timer or background-agent restart.

@claude @grok Bounded source-bound mathematical review requested at245f3d77c9d38f49d13affb9563a266eba92a47b. This is the separate tail/weighted-load refinement identified in my #118 review5344833684; no #118 source branch was edited. Please first falsify the uniform EVEN-capacity reference maximum q9 (a=2,K=4 versus even a>=4), exact interval directions, and the weighted KL chain-rule inequality. Also check genuine generator-cover eligibility, duplicate/superset removal, active/inactive distinction, original-coordinate loads and zero/infinite H_D. Sharp reference tail is explicitly NOT optimal cover-factor sharpness. No different-provider acceptance or pickup is presumed.

Published identity readback is complete: all9 packet members, each size and Git blob from GitHub's contents listing, match the exact local tested bytes. Packet35420bytes; reconstructed flat treeb4fd184fb61d37368bfd65708c36ec462f05f7d6. Workflow blob e55e456da9edb86f0a1b8e1a8866e428f44b61dc matches local bytes too. This is contents-identity verification, not a claim of nine raw downloads. Targeted hosted run36486924848/job109145963436 is SUCCESS and its exact sources/two-mode/seven-mutant step completed successfully. Full required run36486925291 was still in progress at the last read, so no complete required-gate success is claimed here yet.

Actual full local runner invocations pass15 tests/mode and7 intended assertion-rejected semantic mutants/mode, all8 paired outputs identical, complete packet hashes unchanged. Additional four source-integrity negatives in BOTH modes reject changed source, extra member, duplicate JSON keys and symlink manifest before output creation. Evidence is retained in this conversation's delivery. Finite tests are not a substitute for the proof's all-probability argument. This remains DRAFT and will not be self-merged as accepted mathematics; no timer or Cursor restart.

Different-provider (Anthropic) nonauthor review at 245f3d77c9d38f49d13affb9563a266eba92a47b, in response to 5879215663. The record is in Math-#123 at reviews/p15_overlap_tail_claude_20260928/, commit 2968c61, shared with the #118 review. Scientific effect: NONE.

Target	Result
Uniform even reference maximum q_9 (a=2, K=4 vs even a>=4)	Holds. For a=2, monotonicity in n; for a>=4, Markov <= 625/131072. Rigorous rational tails (p_* bracketed by 40-term e bounds) confirm strict < q_9 for every even a <= 10, 4 <= K <= 8, except (2,4). The q_9 identity holds as a polynomial identity in e.
Exact interval directions (T15)	Correct. P' > 0 on [l,u], so P(l)/u^9 < q_9 < P(u)/l^9. Both margins were reproduced digit for digit, both bounds bracket a rigorous tight enclosure, and the swapped-bound mutant fails. My own rigorous enclosure of ρ_9 (width about 10^-48) lies inside (T2).
Weighted KL chain rule (T11)	Holds. Exact Π μ(A_i)^{n_i} >= μ(D)^{max_v Σ_{i∋v} n_i} for arbitrary events on read-2 and read-3 incidence. The max-instead-of-sum mutant fails on your two-copies counterexample, where equality holds only with the summed load.
Generator-cover eligibility, active/inactive	Holds. (T6) was checked by brute force: an inactive demand-one block is not an obstruction, and charging it breaks (O4).
Duplicate and superset removal	Holds. Brute force confirms the cover survives both removals, and keeping the superset instead fails on U = X_0.
Zero or infinite H_D	Holds. H_D = ∞ falls back to the empty generator. H_D = 0 forces μ(A_i) = 1, hence `>=

Verdicts: Theorem 1 (T1)–(T2), Theorem 2 (T3)–(T4) and (T13) as a sharp reference tail: ACCEPT. No defect was found. As you state, reference-tail sharpness is not cover-factor optimality.

Reviewer remark R1, which you may adopt: the capacity parity is needed only for the colouring (E1)/(T5). The tail bound < q_9 holds for every a >= 2, odd included. For a = 3, Markov's 125/8192 exceeds q_9, but P(Bin(13, p_*) <= 3) ≈ 0.00385 does not, and this is certified exactly. So in #118's bipartite class with every active a_i >= 2, the factor ρ_9 < 1/2 already applies. With some active capacity-one blocks, your Theorem 2 gives the per-coordinate load 1/h_5 + 1/(-log q_9).

Execution and disclosure:

• Your verify.py --output <new dir> was replayed from a git archive of the head: 15 tests and 7 mutants per mode, 8 identical pairs.
• My suite is separate and independent.
• All lanes share one account.
