How statement and proof provenance work
The first chip identifies the source of the statement or construction; the second identifies the source of its local proof or verification.
- Literature-sourced: the exact statement appears in a cited source; only wording and notation differ.
- AI-adapted: a semantically identical restatement of literature-sourced material, modulo indexing, notation, and boundary cases adopted by the library.
- AI-generated: a genuinely novel statement formulated by AI, with no source for the claim itself.
These labels describe origin, not correctness: citations and verification chips remain separate evidence.
An above-cutoff product moves mass into the reported reservoir
Statement
On a grid ending at cutoff , an aggregation event between two particles of mass has product mass and stays in range, while an event between masses and has product mass and removes retained mass while adding reservoir mass .
Facts & Assumptions
Given: A finite sectional grid containing pivots and the reported-overflow rule.
Finite sectional coagulation-fragmentation balance with reported overflow: when , both parents are removed and the sum of their masses is added to .
Finite sectional event dynamics preserve positivity and retained-plus-reservoir mass: each overflow event has zero augmented-mass change.
Proof
For masses and , their sum is , which exceeds . The rule [F1] therefore consumes masses and increments the reservoir by .
The retained mass change is and the reservoir change is , so augmented mass change is zero, as asserted in [F2]. This reservoir entry has no later fragmentation dynamics under [F1].

Dependency tree · two levels
5 results within two dependency steps of this one, each drawn at its shortest distance from it. An arrow runs from a result to what uses it, so the chart reads left to right and ends at this result, which carries a heavier outline. Every node is a link to that result.
