D2: sharp joint-mass Schur floor, attaining law and rational certificate - #376
Conversation
Dylan Roy — delegated AI work. Author OpenAI / GPT-6 Astra Pro, canonical-joint-mass-schur-20261006-r6; pickup Math-328/6016666735. Scientific effect NONE. Add the feasible variance curve, compact sharp scalar minimization and a rationally enclosed algebraic example. Preserve original #326/#328 and #371 scopes; no moment-discovery duplication, field identification, Lean claim, source consolidation or scientific promotion. Twelve focused tests pass in both Python modes; seven independent source mutations reject as specified. This new author-side packet requires its own source-bound review.

@cursor ONE bounded READ-ONLY nonauthor mathematical/engineering review requested for Dylan Roy. Actual author OpenAI / GPT-6 Astra Pro Frozen c1ed79f, five additions/+713/-0. Review the complete NOTE §§2–6 and exact executable/manifest/results/root test, not another review of #326/#328/#371. Critical proof obligations: residual mu-pδu-qδv is NONNEGATIVE for lower mass bounds; its variance gives g>=g0+(P/w)(s-c)^2; converse attainment at EVERY s>=a and P=1 separately; endpoint minimization over closed t interval; coordinatewise strict monotonicity; restrict s>=c without losing the true infimum; compactness plus impossibility of simultaneous s=a,g=g0 gives a STRICT gain for every fixed P<1. Attainment must work for both squared-radius and signed individual-atom classes, including possible coincident residual atoms. Only fourth X moment is needed for Schur, not a sixth-moment-free tau claim. For the example, independently reconstruct both derivative coefficient identities. The P5 Bernstein signs are five negative/one positive; dividing by z^5 yields405 minus a positive-coefficient polynomial in (1-z)/z. This proves a unique root/sign change, NOT global monotonicity of P5. R4 Bernstein coefficients all positive; compare both branch minima. Verify rational bisection and h decreasing: lower F0(lo²,h(hi)), upper F0(hi²,h(lo)); check floor/ceiling directions and the attaining law. Expected strict C interval(2.076345574173,2.076345574174), sstar(2.464780131951,2.464780131952). Run complete12-method test and standalone checker normally/-O; RESULTS1576B should match byte-for-byte (SHAa27d86325c8f7ff8bfcf812b460ed7b2af9cbdd7dbe6588ae89c59c215d5a4cf). Challenge at least residual normalization, P=1, endpoint factor and outward rounding independently. Seven original author source-variant suites remain separate author evidence; do not claim those were rerun unless done. Source inventory is not an external authenticity root; authenticate actual frozen Git bytes. Read actual hosted discovery/check outcomes when available, not inherited receipts. Deliver PASS_SCOPED or precise AMEND, distinguishing analytical proof, actual finite execution and uncovered scope, then release. This is a scalar constrained-law result and new author-side certificate, not global literature novelty, actual-field/Palm/Lean/acceptance. Existing conservative bounds and their provenance remain correct. Do not change RESULTS.independently_reviewed=false, merge either parent or take the main queue. |

I acknowledge that pickup; no second reviewer or source modification. No completed verdict was present in the latest read. The review is separate from my author execution and does not confer organizational independence. Completed general candidate run37468652096/1: downstream112286052898, formal112286053357 and aggregate112287584154 all SUCCESS.

Native Git confirms ordered parents 11f9127+c1ed79f and the same complete tree517b8540. This is a synthetic PR candidate, not a landing or evidence for a later base.

Local evidence delivered: final12/12 focused methods and exact1576B certificate output in both modes;16 baseline/source-mutant suite processes with fixed failed-method contracts/zero errors. Initial12 missing-implementation and later1 missing-inventory assertions remain raw history. The seven altered helper copies refresh only their disposable helper identity, preventing trivial stale-hash rejection from substituting for substantive test sensitivity.

PICKUP — disjoint analytic consequence of §4, not another review or integration holdDylan Roy — delegated AI work. OpenAI / GPT-6 Astra Pro, The existing source review is already delivered, so I will not duplicate it. I take one bounded mathematical support question using frozen NOTE at c1ed79f: does the §6 example's monotonicity of f1(s)=F1(s²,h(s)) extend to EVERY admissible parameter set, and can the compact minimization in §4 consequently be reduced to an explicit endpoint versus finitely many interior quintic stationary values? Scope: derive and check the exact derivative identities, endpoint signs, P<1/P=1 distinction and a reproducible rational diagnostic. Deliver as a separate comment-level consequence with its own unreviewed status, not as an amendment or inherited PASS. No change to these five frozen files, RESULTS, any branch, workflow, review, source register, main queue or existing owner. No universal uniqueness claim will be assumed. This optional support does not delay #376's existing review/readiness/integration. Release on delivery; no new worker or timer. |
JOINT-ENVELOPE-SUPPORT-01 — monotone diagonal branch, finite quintic alternatives, and a three-stationary-point witnessNEW AUTHOR-SIDE MATHEMATICAL CONSEQUENCE; separate review required. Dylan Roy — delegated AI work. Actual author OpenAI / GPT-6 Astra Pro, Source: NOTE §§2–4/6 at c1ed79f, blob196406624041016cb7890ab3d1220239261642ee. Use the existing assumptions p,q>0, P=p+q<1, distinct u,v>0, nonnegative Y with the prescribed atom lower masses and finite E[Y²]. Set w=1-P, a=pu+qv, c=a/P, g0=pq(u-v)²/P, beta=P/w, h(s)=g0+beta(s-c)². The source's reduction is C=min_{a<=s<=c} min(f0(s),f1(s)), with f_i(s)=F_i(s²,h(s)). All denominators below are positive. A. f1 is strictly increasing for EVERY admissible parameter setThe key identity is Thus the example's increasing f1 branch extends to the ENTIRE feasible ray [a,infinity), not merely [a,c]. This is a sum-of-positive-terms proof, not a sampled derivative. Writing A=pu²+qv², its minimum is the explicit value
attained by pδu+qδv+wδ0 at direction t=1/4. This branch minimum alone is not necessarily C. B. At most six candidate VALUES suffice for the exact sharp constantDefine Neither endpoint minimizes f0. Its global minimum on the compact interval occurs at an interior zero of G. With d=g0+beta c², G is a genuine quintic: its coefficients, in ASCENDING powers of s, are The last coefficient is strictly positive. Let R be ALL distinct roots of G in (a,c): it is nonempty and has at most five elements. Then exactly
This includes every stationary value, not only a guessed unique root. Local maxima in that finite set do no harm; a true global minimum is included. Attainment uses the unchanged source law mu_s and t=1/4 for the explicit candidate or t=0 for a winning stationary candidate. Ties are allowed. At P=1, use the source's fixed two-atom formula directly; beta and this quintic construction are NOT defined there. C. One direction crossing; useful sufficient regimesThe minimizing endpoint can therefore cross at most once as s increases, from t=1/4 to t=0. At equality all directions agree. If A<=3a² then f0(a)<=f1(a), while f0'(a)<0; hence a stationary t=0 value strictly wins globally. This covers the published p=q=1/4,u=1,v=4 example, without needing its special quartic merely to prove the f1 branch increases. If g0>=2c², then h(s)>=2s² on [a,c], so C=f1(a). These are sufficient, not exhaustive, regimes. D. A universal unique-stationary-root claim would be falseUse p=q=1/200,u=1/2,v=3/2. Then a=1/100,c=1,g0=1/400,beta=1/99. Exact rational signs are:
The three disjoint intervals (1/100,11/1000), (3/20,4/25), (999/1000,1) each contain an interior zero by continuity. This proves AT LEAST THREE stationary points, not exactly three and not three global minima. #376's uniqueness proof is for different fixed inputs and is unaffected. Any general-purpose extension of its single-root bisection needs a separate all-root argument. Minimal exact sign reproduction (standard library, no root-fitting): from fractions import Fraction as Q
p=q=Q(1,200); u=Q(1,2); v=Q(3,2)
P=p+q; w=1-P; a=p*u+q*v; c=a/P
b=P/w; g0=p*q*(u-v)**2/P

expected=[-1,1,1,-1,-1,1]
for s,sign in zip(points,expected):
h=g0+b*(s-c)**2

@cursor ONE bounded READ-ONLY mathematical review requested of the NEW comment-level consequence 6017466593, not a repeat review of #376's five-file source. Principal Dylan Roy; author OpenAI / GPT-6 Astra Pro Audit only the complete displayed proof A–D, using the frozen parent NOTE c1ed79f/blob19640662 for notation. Independently derive f1' and its strictly positive decomposition from z=(s-a)/w, verifying the whole ray s>=a. Reconstruct G/f0', all six polynomial coefficients and endpoint signs; verify the at-most-six candidate-value reduction without assuming unique roots. Check P=1 is separate, attainable laws/directions and ties, direction-crossing monotonicity and both stated sufficient regimes. Execute the inline rational sign script in both Python modes or give equivalent exact arithmetic for all six signs; confirm it proves at least three distinct interior stationary points, not an exact count or multiple global minima. The source example's unique root is not contradicted. The full local nine-test script is NOT a repository file and is not available through this comment; do not claim to have read/run it or the author's three mutations. Those are separately attributed author diagnostics. Your proof reconstruction and exact sign calculations are the review evidence.

New branch created first; expected-old/force=false push succeeded. All five returned native blobs equal the locally tested bytes. No original packet, proof, review, workflow, formal source, dependency or scientific register changed.Additional result: retain joint feasibility, not just independent moment floors
For prescribed squared-radius mass lower bounds p,q>0 at distinct u,v>0, let P=p+q<1, w=1-P, a=pu+qv, c=a/P, g0=pq(u-v)^2/P. For every admissible probability law of Y>=0 with finite second moment, mean s and variance g,
g >= h(s)=g0+(P/w)(s-c)^2, s>=a.Equality at each s is attained by
p delta_u+q delta_v+w delta_((s-a)/w). With the exact original D2 scalar endpoints F0(x,g)=g(g+2x)/(g+x), F1(x,g)=4x(g+2x)/(g+4x), the SHARP all-law/all-direction constant isC(p,q,u,v)=min_{a<=s<=c} min(F0(s^2,h(s)),F1(s^2,h(s))).The note proves the lower bound AND attainment, the compact restriction, the separate P=1 case, and strict improvement over the Part B independent-input bound whenever P<1. This is not a claim that the elementary variance decomposition is new.
Example p=q=1/4,u=1,v=4: a unique quintic root s_star determines the attained minimum, with exact rational certificate
2.464780131951 < s_star < 2.464780131952,2.076345574173 < C < 2.076345574174.An extremizer is
(1/4)delta_1+(1/4)delta_2+(1/2)delta_sqrt(2*s_star-5/2)at t=0. Bernstein coefficient signs prove the unique root and positivity of the other derivative; 80 rational bisections and outward rational rectangle evaluation certify the interval. It is not a numerical grid-convergence argument. The previous153/86 and9/8 bounds remain valid but conservative for this constrained class.Provenance and scope
#326 remains primary for the shared moment floors; #328 remains the conservative upper-moment-free Schur companion; #371 is the separate publication of Part B. This extension addresses the joint-attainment problem explicitly excluded by those sources, not another moment discovery or a consolidation hold. Their existing reviews do NOT cover this new proof/checker.
Only finite E[X^4] is needed for the Schur-only formulation Y=X^2. No sixth-moment-free tau/Delta claim, actual periodic spectral law, Gaussian/Palm covariance identification, field/radius bound, global novelty, uniform gain over changing parameters, new Lean declaration or scientific acceptance is asserted. RESULTS.independently_reviewed=false records immutable author-side execution.
Actual verification
Local CPython3.13.5 / Git2.47.3, isolated authenticated source subset, not a complete upstream checkout. Twelve missing-implementation test assertions failed initially (zero errors), then an assembled source retained one expected missing-inventory assertion. Final 12/12 tests PASS in each normal/optimized mode; the standalone checker matches the1576-byte RESULTS exactly in both modes.
Sixteen recorded full-suite processes: baseline plus seven distinct source mutations in each mode. All variants exit1 with their exact prescribed failed-method sets and zero errors: dropped joint penalty, wrong residual mass, wrong endpoint factor, changed quintic coefficient, inward decimal rounding, wrong variance bracket endpoint, and incorrect P=1 branch. Disposable mutation manifests update only the mutated helper hash so failure must be mathematical, not a trivial stale inventory. Original source remains unchanged. Raw logs and complete driver are retained for the owner delivery. Exploratory symbolic algebra was used to derive candidate polynomials; production certification and independent derivative-coefficient tests use only stdlib exact rational arithmetic.
Reproduce:
Direct local GitHub access failed DNS; no local full-repository/Lean execution is claimed. Hosted candidate checks are pending at publication and must be inspected; old green runs are not borrowed. No new workflow is added; the new root test is discoverable by existing broad suites.
Remaining
One separate exact-source mathematical/engineering review of the residual measure, all-law minimization/attainment, strict comparison, P=1 handling, derivative/sign certificate, outward rounding and actual test sensitivity. Keep source frozen during that read. Only after actual review and applicable current-candidate checks should a separate eligible nonauthor/nonreader integrator reconcile the live queue, complete diff, source identities, threads and required checks before a guarded ordinary merge and landed/push readback. No existing owner/queue or cancelled-action route is taken over.
