    Source documentation

    Particle monotonicity requires bounds only on genuine terminal paths and legal birth times; the explicit construction has no mass elsewhere.

    theorem particleEval_mono_on (t : Tree ι E) {F G : List ι → ℕ → ℝ}

  5. def OAI.SignedDisk.IntrinsicMarks.markIndicator line 66

    Source documentation

    Intrinsic marks as an actual function on prefixes, with first-crossing reset. Prefixes outside the tree have zero charge.

      | .leaf v, n, [] => if δ < ‖direction e v-n‖ then 1 else 0

    Source documentation

    Turning a genuine pathwise switch bound into the global budget uses exact occupancy, rather than a false assumption that every particle is born at a root.

    Source documentation

    Product-rule expansion over all terminal label histories. The carried mass and its derivative are updated by the exact Leibniz rule.

    Source documentation

    This is the exact zero-row-sum cancellation. No unsigned path-potential bound is used and the parent prefix may be arbitrarily large.

    Full finite-history signed flux estimate, with all stochastic prefix weights kept. The node bound is the tail oscillation, not the old envelope.
