Tachiko Work is a semantic workspace for structured data where humans and AI operate on typed meaning instead of raw cells. For the GPT-6 Astra Challenge, Astra turns natural-language intent into typed proposals; Tachiko’s deterministic Rust engine validates formulas, dependencies, and impact before anything changes. Tachiko Sheet provides the familiar spreadsheet experience on top. Public pre-alpha.

Could you build this?
No Building a deterministic Rust calculation and formal dependency verification engine for semantic data structures requires specialized compiler and formal methods engineering.
What it would actually take: The architecture requires a custom reactive DAG (directed acyclic graph) engine in Rust paired with a formal type-checking and constraint solver subsystem. The hard part is mathematically guaranteeing deterministic execution, dependency isolation, and cycle detection across arbitrary user-defined semantic proposals in real time. This requires deep expertise in programming language theory, type systems, and systems engineering.
