Final Validation Report: LG24 Service Level Agreements

Updated: 2026-09-06

1. Human Verdict

Formalized. The five named propositions and two selected queueing/SLA displays have closed proofs on the stated admitted-stream model. No paper-level issue or additional assumption is recorded. Independent human review has not yet been recorded.

2. Closeout Status

3. Source and Scope

The source is the active private manuscript revision. The normal scope is its five propositions: reciprocal capacity, extreme efficiency, extreme equity, price of equity, and centralization gain. The stationary GPS response-tail and all-request SLA rate-fraction displays are selected supplemental targets. Algorithms, simulations, figures, captions, and ordinary prose are not part of this formalization.

4. Researcher Summary of Checked Results

Result Comparison with source
Proposition 2.1 (equivalent reciprocal-capacity representation) Exact.
Propositions 2.2 and 2.3 (extreme efficiency and extreme equity) Exact.
Proposition 2.4 (price of equity) Exact.
Proposition 2.5 (centralization gain) Exact.
Equation (1) (stationary response-time tail) Exact.
Unnumbered all-request fraction consequence following Equation (2) Interpretation clarified: stationary probability/intensity fraction, without a raw-arrival empirical-frequency limit. Reading.

5. Remaining Boundaries and Gaps

None.

6. Additional Assumptions Beyond Paper

None.

7. Proof-Strategy Deviations

None.

8. Proof Tricks Worth Reusing

None.

9. Generalizations, Conjectures, and Extensions

No additional generalization is established here.

10. Source Clarifications and Exact Readings

The queueing memo specifies the stationary probability/intensity interpretation of the all-request fraction; no raw-arrival empirical-frequency theorem is claimed.

11. Paper Issues or Caveats

None.

12. Detailed Formalization Evidence

The current review surface has ten transparent specification/proof pairs: five named propositions, two queueing/SLA displays, and three supporting optimization or relative-cost results. Their source-to-Lean judgments compare the selected manuscript with the expanded mathematical definitions. Lean checks the proof endpoints and their dependency closure.

The active queueing route constructs the stationary response tail from the admitted-stream model. No tail certificate or stationarity witness is supplied as a theorem premise.

13. Paper Assumption Provenance

No separate paper-facing assumption declaration is configured. The visible premises of the active specifications are source model conditions or are derived in Lean. In particular, neither a response certificate nor a stationarity witness is a theorem-facing premise.

Current Canonical Evidence

Generated from the configured source-condition surface and exact current statement digests in the canonical assumption-provenance sidecar. Model, agent, and automated checks are identified as such; no human review is inferred.

Assumption declaration Lean declaration Source location / statement Assumption validators Comments
None none None None No paper-facing assumption declarations are configured.

14. Displayed Formula Provenance

The selected response-tail and rate-fraction displays each have an exact paper-facing Spec and theorem route. The tail is constructed from the active source model; the rate fraction is derived from that tail rather than from a separately supplied stochastic conclusion.

The supporting relative-centralization display also has its own specification and proof. It uses the source’s relative normalization and is available for an arbitrary finite nonempty Borough domain; Proposition 2.5 separately requires at least two Boroughs for its strict improvement.

15. Library Lift Pass

The optimization results use reusable finite minimization and algebraic tools. The source-facing GPS/FCFS queue construction remains paper-local. Its active proof route uses only the standard Lean logical axioms.

16. DAG Audit

The dependency diagram (TeX source) follows the current five propositions, the two selected queueing/SLA displays, and the supporting city optimizer and relative-cost identities. Proposition 2.4 is the relative all-request price-of-equity result; Proposition 2.5 is centralization. The rendered PDF was visually inspected on 2026-09-06; its labels and nodes are readable, with no clipping.

17. Validation Checks

All ten selected source-to-Lean comparisons are reviewed. The current Lean-owned graph verifies their specification/proof pairings and contains no placeholder proof or separate paper assumption. Strict closeout completed all ten checks on 2026-09-06; the closure receipt records the accepted graph and focused build. Currentness can be checked with python3 scripts/final_closure_receipt.py --paper LG24ServiceLevelAgreements --check.

18. Paper Definitions Checked

The paper-facing interface exposes the fixed-load feasibility, costs, objectives, capacity-share and effective-load expressions used by the five propositions. It also exposes the global SLA-subsystem steady condition, the separate target-local margin, the stationary response-tail contract, and the all-request response fraction needed for the selected displays. These are source-facing vocabulary and formula context, not independent theorem credit.

19. Named Theorem Statements Checked

Equivalent Reciprocal-Capacity Representation

Paper statement. The original fixed-load and reciprocal-capacity programs have the same minimizers on the stated finite positive-feasibility domain.

Lean interface. paper_prop_opt_reformulationSpec and paper_prop_opt_reformulation prove equality of the minimizer predicates for every loss on the same domain.

Status. Formalized.

Extreme Efficiency

Paper statement. The displayed square-root endpoint uniquely minimizes the efficiency objective on the fixed-load feasible set.

Lean interface. paper_prop_extreme_efficiencySpec and paper_prop_extreme_efficiency retain the source domain and the complete minimizer-plus-uniqueness conclusion.

Status. Formalized.

Extreme Equity

Paper statement. There is an efficiency-best equitable endpoint with a common all-request cost within each category.

Lean interface. paper_prop_extreme_equitySpec and paper_prop_extreme_equity prove the existential endpoint and its category cost-level conclusion.

Status. Formalized.

Price of Equity

Paper statement. The relative price has the printed Pearson identity, bounds, zero characterizations, and capacity-scaling classification.

Lean interface. paper_prop_price_of_equitySpec and paper_prop_price_of_equity prove all displayed clauses from the stated finite fixed-load model.

Status. Formalized.

Centralization Gain

Paper statement. With at least two Boroughs, city-level centralization has the displayed strict-delay improvement and relative-gain comparison.

Lean interface. paper_prop_centralizationSpec and paper_prop_centralization retain the nontrivial-Borough condition and prove both source clauses.

Status. Formalized.

Selected Queueing Displays

paper_stationary_gps_response_tail and paper_sla_from_stationary_gps_tail respectively prove the selected stationary tail and all-request Palm/intensity fraction under the visible source-model conditions. Both are formalized; neither imports a cited-tail conclusion.

20. Paper-Facing Statement Validator Ledger

21. Source-Coverage Audit Ledger

The source map and active-version map select the five propositions in the current manuscript, the two queueing/SLA displays, and three supporting results listed above. Each has one reviewed specification and proof route. Definitions are inspected within their governing result’s expanded comparison; they do not add result credit. The review packet collects those source-to-Lean comparisons for human assessment.
