Tensorless Exact-Ledger Sandbox: Deterministic Integer Policies and Their Boundary with Reference FPM

Tensorless provides a deterministic exact-ledger sandbox for FPM-inspired finite-resource dynamics. Its synchronous sandbox represents energy and action in exact one-third-micro-action subunits, route cost in an unsigned 3×3 integer ledger, and momentum in a separate signed 3×3 ledger. Each tick is a snapshot transaction: reserve action, form payload and momentum proposals, resolve competing capacity claims globally, commit accepted transfers simultaneously, record rejected transfers externally, and close the action-replenishment ledger. Exact ledger closure is not exact conformance to every transition in the Python reference. Tensorless realizes an exact equilibrium-style signed ledger under its declared contract; it is not yet an exact integer implementation of the complete local transport dynamics.
