  description: >
    GPT Action schema for Primordial OS Runtime. Routes bounded mesh commands into
    Substrate trace capsules, Primordial Periodic Table references, Primordial Periodic
    Alchemical Output, HIR × OAM receipts, lexicon state, workspace-local overlay
    proposals, and audit receipts. Canonical sources and the canonical Primordial
    Lexicon remain read-only.

      description: >
        Converts a user command or threadroom post into a trace capsule, resolves PPT
        elements, returns alchemical output, applies HIR × OAM receipt boundaries, and
        stores a workspace-local receipt. This endpoint never mutates canonical source
        artifacts or the canonical Primordial Lexicon.
