Identifying where to innovate in a dense technical domain—such as operating systems or hardware/software co-design—is fundamentally a search problem in a highdimensional knowledge space. Existing approaches rely on keyword search, citation proximity, or human intuition, none of which formalise the notion of an unexplored region that is simultaneously relevant to a target goal and absent from prior art.  \nWe present Topological Void Analysis (TVA), a mathematical framework that defines topological voids as triads (A, B, C) in a dense-sparse hybrid embedding space. A void requires three conditions: (i) both concepts A and B are semantically cohesive with domain anchor C; (ii) their pairwise similarity falls within a calibrated marginality band—avoiding both obvious combinations and unrelated noise; and (iii) they share a sparse lexical bridge while the geodesic midpoint on the embedding hypersphere is unoccupied.  \nApplied to ∼ 140k indexed documents, TVA generates 2,128 invention candidates across 96 targets; 90% survive automated quality filtering, yielding 191 REVISE and 1 APPROVE verdict from four-specialist adversarial review (0.05% end-to-end) . Two case studies demonstrate the framework surfaces non-obvious connective tissue rather than merely obvious related pairs.  \n1 Introduction  \nModern software systems, especially at the systems-software layer, evolve through incremental invention: a developer notices a gap between two subsystems, proposes an abstraction to bridge them, and the community iterates toward a patch or patent. The noticing step is bottlenecked by human attention and domain breadth. A single engineer cannot simultaneously hold in mind the locking semantics of the Linux scheduler, the memory-ordering guarantees of eBPF JIT output, the ELF relocation model, and the BPF verifier’s type system well enough to recognise that an IFUNC-style dispatch contract could unify the latter three.  \nThis paper asks: can we formalise and auto-  \nmate the discovery of unexplored technical gaps?  \nWe answer yes, and make the following contributions:  \n1. A formal definition of a topological void (Section 4): a triad (A, B, C) satisfying domain cohesion, calibrated marginality, and sparse lexical bridge conditions in a hybrid densesparse embedding space.  \n2. A vacancy probing mechanism (Section 5) based on spherical linear interpolation (SLERP) that rejects pseudo-voids whose midpoint is occupied by existing documents.  \n3. An adaptive threshold calibration procedure (Section 6) that derives domain-specific marginality bounds from corpus statistics, removing manual tuning.  \n4. A large-scale empirical evaluation (Section 8) with two detailed case studies demonstrating that TVA surfaces non-obvious yet technically grounded innovation candidates.  \n2 Background and Motivation  \n2.1 Technical Knowledge as an Embedding Space  \nPre-trained embedding models map technical documents into a high-dimensional unit sphere [7] . Points close in cosine distance share semantic content; distant points are unrelated. A knowledge corpus K is a finite set of such points.  \nInnovation in this view is the act of bridging two concepts A, B that are not yet co-located in K, provided their combination is relevant to a target goal C.  \n2.2 Geometric Convergence Across Model Scales  \nA key theoretical underpinning of TVA is the Platonic Representation Hypothesis [8]: sufficiently trained models—regardless of architecture, modality, or scale—converge toward a common statistical geometry of their shared training world. Concretely, the pairwise distance structure of a compact embedding model (BGE-M3, 1024D) and a frontier LLM are approximately isometric: if cos(dense(A), dense (B)) ≈ 0 in BGE-M3 space, th","cbCaiqLbYI4uKgx6","https://ap.wps.com/l/cbCaiqLbYI4uKgx6","pdf",327480,4,1,11,"English","en",105,"# Introduction\n# Background and Motivation\n## Technical Knowledge as an Embedding Space\n## Geometric Convergence Across Model Scales\n## Limitations of Prior Art Search\n## The Marginality Principle\n# Why Standard Approaches Fail","[{\"question\":\"What problem does Topological Void Analysis (TVA) address in technical innovation discovery?\",\"answer\":\"TVA targets the challenge of finding unexplored technical gaps in a dense knowledge domain where existing searches retrieve known content rather than identify missing, goal-relevant regions.\"},{\"question\":\"How does TVA define a “topological void” mathematically?\",\"answer\":\"A void is defined as a triad (A, B, C) in a hybrid dense-sparse embedding space, requiring domain cohesion with anchor C, calibrated marginality between A and B, and a sparse lexical bridge with an unoccupied geodesic midpoint.\"},{\"question\":\"How does TVA generate and validate invention candidates at scale?\",\"answer\":\"TVA uses a vacancy probing mechanism based on SLERP to reject pseudo-voids whose midpoint is already occupied, then applies adaptive threshold calibration from corpus statistics;
