This record contains an audit-grade AASC endpoint-exclusion manuscript for the Hodge Conjecture: The Hodge Conjecture by Exclusion of the Empty Cycle-Fiber EndpointAn AASC Endpoint-Rigidity Proof for Rational Hodge Classes via Cycle-Fiber Occupation The manuscript works on the fixed classical Hodge/cycle carrier. For a smooth projective complex variety XXX, codimension ppp, and rational Hodge class α∈Hdgp(X),\alpha \in \mathrm{Hdg}^p(X),α∈Hdgp(X), the positive endpoint is the nonemptiness of the rational cycle-class fiber FX(α)={Z∈CHp(X)Q:cl⁡Q(Z)=α}.F_X(\alpha)=\{Z\in CH^p(X)_{\mathbb Q}: \operatorname{cl}_{\mathbb Q}(Z)=\alpha\}.FX(α)={Z∈CHp(X)Q:clQ(Z)=α}. The proof does not introduce a new algebraic-geometric construction of cycles and does not redefine Hodge classes, Chow groups, rational coefficients, the cycle-class map, or algebraic cycles. Instead, it gives an AASC endpoint-rigidity argument showing that the empty cycle-fiber endpoint cannot be used as a same-carrier endpoint-defeating branch. Proof Architecture The manuscript separates raw mathematical content from endpoint-governing use. The positive branch is: FX(α)≠∅.F_X(\alpha)\neq\varnothing.FX(α)=∅. The bare negative branch is: FX(α)=∅.F_X(\alpha)=\varnothing.FX(α)=∅. Empty-fiber content is treated as lawful in ordinary mathematical roles: raw syntax, obstruction content, nonmembership content, support-level reasoning, hypothetical local content, or ordinary negative theoremhood. It becomes AASC-relevant only when used to defeat the official Hodge endpoint on the same fixed Hodge/cycle carrier. Under such endpoint-defeating use, the proof route is: empty-fiber counterforce is classified as endpoint use; endpoint use instantiates the kernel of reference, standing, admissibility, and irreversibility; the kernel forces the A+A^+A+ consequence layer; A+A^+A+ excludes independent same-domain endpoint-status discriminators; native empty-fiber counterforce is exhausted into bridge-neutralized status, support-only status, bookkeeping, carrier/domain shift, or the independent cycle-fiber discriminator Dfib(X,p,α)D_{\mathrm{fib}}(X,p,\alpha)Dfib(X,p,α); in the live exact-complement reductio subproof, the first four routes are unavailable; the local empty-fiber countercase therefore induces Dfib(X,p,α)D_{\mathrm{fib}}(X,p,\alpha)Dfib(X,p,α); endpoint use supplies Nfib(X,p,α)N_{\mathrm{fib}}(X,p,\alpha)Nfib(X,p,α), hence ¬Dfib(X,p,α)\neg D_{\mathrm{fib}}(X,p,\alpha)¬Dfib(X,p,α); the contradiction discharges the local assumption FX(α)=∅F_X(\alpha)=\varnothingFX(α)=∅; since X,p,αX,p,\alphaX,p,α were arbitrary, every rational Hodge class has nonempty rational cycle-class fiber. Lean4 Audit Support This record is paired with the Lean4 audit repository: GitHub: somamaley-ux/AASC-Hodge-Endpoint-Lean-Audit DOI: 10.5281/zenodo.20640238 The Lean layer is an audit support layer for the AASC/Hodge endpoint bridge and closeout surface. It is not presented as a first-principles formalization of all Hodge theory. Its intended role is to check the endpoint-role bridge, the empty-fiber counterforce exhaustion surface, the discriminator closure interface, and the final Hodge endpoint closeout, conditional on the declared Hodge/cycle model adequacy boundary. Scope and Boundary This manuscript should be read as an AASC endpoint-rigidity proof, not as a Lefschetz-type theorem, motivic construction, Abel–Jacobi or normal-function argument, standard-conjectures proof, deformation/spread argument, or explicit cycle-construction method. Classical Hodge-theoretic objects are used to identify the official carrier and endpoint. The branch-exclusion mechanism is AASC-internal: it concerns the admissibility of using the empty cycle-fiber branch as endpoint-defeating counterforce on the same fixed Hodge/cycle carrier.
