Final Validation Report: Who is in Your Top Three?

Updated: 2026-09-06

1. Human Verdict

The formalization covers ordered-tier design invariance, pairwise and aggregate convergence results, randomized approval rules, the Mallows special case, and the exact dynamic program for two candidates’ joint locations. The dynamic program has a degree-six bound on arithmetic operations in its stated unit-cost model.

Propositions 2 and 4 include their finite-sample bounds. The source clarifications record the one-sided score-gap cases that make their rate conventions explicit.

2. Closeout Status

3. Source and Scope

The canonical pinned source is arXiv:1906.08160 / HCOMP 2019:

The independent source inventory covers the finite ranking model, all three definitions, all nine named theoretical results, displayed probability and rate formulas, appendix proof steps, fixed mathematical examples, and the advertised Mallows joint-location algorithm. Raw datasets, fitted empirical estimates, figure pixels, and qualitative deployment recommendations are not mathematical theorem targets. The Durham numerical comparison is nevertheless checked exactly from the printed thousandths because it supports a source mathematical claim.

4. Researcher Summary of Checked Results

Result Comparison with source
Definitions 1–3 Exact.
Proposition 1 Exact.
Proposition 2 Exact.
Proposition 3 Exact.
Proposition 4 Exact.
Theorems 1–2; Mallows corollary Exact.
W-selection, Durham, and high-noise examples Exact.
Joint-location dynamic program Exact.

5. Remaining Boundaries and Gaps

None.

6. Additional Assumptions Beyond Paper

None.

7. Proof-Strategy Deviations

None.

8. Proof Tricks Worth Reusing

9. Generalizations, Conjectures, and Extensions

The dynamic-program layer is source-independent enough to be a candidate for future extraction into the reusable Mallows library. A sparse table over only reachable states should improve the dense degree-six count, but no stronger runtime theorem is claimed here. A separate rational or floating-point implementation could connect exact semantics to executable numerical plots; that would be an engineering extension rather than an unproved paper endpoint.

10. Mathematical Typos or Other Fixes Suggested in the Source Paper

None.

11. Paper Issues or Caveats

No source-theorem correction is claimed. The source’s word “efficient” is made precise by a degree-six dense arithmetic-operation bound for the exact joint-location recurrence. Proposition 1 uses the source’s uniform random tie rule, including equality cases; it does not add a generic no-ties condition.

12. Detailed Formalization Evidence

The source-curated inventory retains 66 mathematical items. The current selected source map retains 15 result contracts. Current review records cover the selected statements and their governing definitions. Definitions and algorithms are reviewed through their actual predicates, functions, and execution rules.

The source map connects the exact source passages to the expanded statements and models. Each selected result has a separate proof endpoint; the typed Lean graph checks its dependencies and axiom closure. Section 20 links the current review ledgers.

13. Paper Assumption Provenance

The selected models expose score and probability laws, randomized weights, ordered nonempty tiers, Mallows parameters, and valid approval cutoffs. These source conditions are carried by the actual semantic prerequisites; no algorithm-correctness conclusion is assumed.

14. Displayed Formula Provenance

The selected rate results retain the Chernoff expressions and finite-sample bounds. The source clarifications state the one-sided score-gap readings. The example and algorithm routes include the printed Durham arithmetic, Mallows insertion probabilities, and pair-location recurrence. Supporting formula presentations remain source context rather than additional named result claims.

15. Library Lift Pass

The exact Mallows pair-location dynamic program and its PMF semantics are natural candidates for the shared ranking library. No unresolved library certificate supports a final paper conclusion.

16. DAG Audit

docs/DependencyDAG.tex shows the dynamic program as a green formalized algorithm node downstream of the Mallows repeated-insertion support. The fixed counterexample remains a separate green result because its mathematical proof does not rely on trusting historical plotting code. The rendered docs/DependencyDAG.pdf is rebuilt from that TeX source and visually inspected after the update.

17. Validation Checks

The proof endpoints include the displayed rate and finite-sample clauses. The closeout record records build and acceptance evidence for its pinned inputs. The targeted closeout command is python3 scripts/run_paper_closeout.py --paper GGSG19TopThree --plan-identity <current-plan-identity>.

18. Paper Definitions Checked

The checked definitions include common limiting outcome, normalized rate, feasible rate maximization, tier goals, approval mechanisms, Mallows laws, and the repeated-insertion pair-location process and dynamic program.

19. Named Theorem Statements Checked

Propositions 1–4, Theorems 1–2, the Mallows no-randomization corollary, the selected randomization results and counterexample, and the arbitrary-pair dynamic-program correctness and operation bound have checked endpoints.

20. Statement Review Evidence

The current source-to-statement assessment and exact review targets are recorded in the following artifacts. Mathematical scope and qualifications are explained with their named results above.

21. Source-Coverage Audit Ledger

The 66-item source inventory distinguishes selected result contracts, source models, repeated presentations, and proof support. The selected comparison surface has 15 direct result judgments and 20 prerequisite judgments. Raw empirical data and plots are outside normal theorem scope; the printed Durham arithmetic is retained as a mathematical example.
