SurfaceMind and SurfaceDelta

Verified operational surfaces and bounded graph patches for small and large language models

Language models are often asked to produce complete answers, pages, reports, dashboards, or interfaces in one generation. This gives the model too much responsibility: it must select sources, preserve state, choose layout, generate all text, maintain internal consistency, and express the result in a renderable form. Small models suffer most, but large models also produce malformed structures, unsupported claims, and destructive rewrites.

SurfaceMind separates intelligence from rendering and authority. It compiles exact sources and governed state into a versioned Semantic Surface Graph. A model operates the graph through small, schema-bound SurfaceDelta patches. A deterministic validator checks base version, target existence, citation spans, text budgets, ordering, authority, and surface invariants before the renderer updates the view. The model never generates authoritative pixels and never owns truth.

The architecture externalizes working memory into a visible surface. A compact local model can classify, extract, rank, repair, or patch one region instead of regenerating an entire answer. The system preserves exact source spans, evidence, versions, omissions, and receipts. SurfaceMind's central empirical claim—matched 4B tasks perform better through SurfaceDelta than raw full-answer chat—remains a named go/no-go experiment, not a completed result.
