Separate thorough review checkpoint for The source/diff/declaration review covers the public 55-module upstream closure, all 58 content files in bounded slices, every port/optimization/follow-up delta, endpoint definitions and actual compiled types, primary citations, profiles and complete compiled trust evidence. The full 14-file latest delta is inspected. No original declaration is removed; all four actual card theorem types are unchanged. Latest findings are repaired: Toda's necessity statement is qualified by uniformity across arbitrary laws and permission to borrow; no impossibility is inferred for a fixed capped household. The primary November 2020 draft was checked. A broader audit identifies Ma-Toda's March 2021 Corollary 2.10 and standing/uncapped scope; verifies Walsh-Young's November 2025 numerical edition and distinguishes its competitive model; removes unverified exact textbook/Clarida comparison labels and historical bisection attribution while retaining credit. The 14 MPC/derived/caller APIs lose unused impatience premises, and their callers are updated. Earlier source and proof-sharing repairs remain present, including literal normalized-clearing scope, verified Light/Acikgoz/Carroll-Shanker editions, shared envelope/policy/saving/cap/floor/concavity/Euler arguments and reuse of the existing zero-shift lemma. Local checks pass: warning-free build, generated indexes, style, repository-wide static quality, all 15 slow linters and compiled axiom/option/card audits over 57 modules / 1,024 textual / 1,656 compiled declarations. Only Classical.choice/propext/Quot.sound allowed; no sorry/admit, custom axiom, unsafe/partial/native_decide, forbidden override or suppression. Fixed root, pins, manifest and infrastructure unchanged. Fresh exact-source clean control builds are running. Required CI 39149121789 and independent review request remain pending. The completed review will give a clear conclusion after these results arrive; earlier receipts do not validate this head. |

Advisory cross-file review against Lean Pool's supervisory rubric. This is not by itself a significance, source-verification, or merge verdict. [Low impact] No actionable defect was found in the follow-up, but external source, license, provenance and exhaustive novelty checks remain open. SummaryAdds conditional uniqueness and bisection for normalized clearing in capped log-household models, including finite Tauchen earnings chains.

"summary": "The complete 58-path import is a substantive, coherent formalization of capped household optimization, stationary distributions and equilibrium-rate comparison. The independent team read all 57 Lean files and the project card. We then reviewed the author's eight-file producer refactor in full and authenticated the unchanged bodies. My six-file follow-up corrects mathematical comments and model-scope notes while preserving every noncomment proof, statement and import byte of that authored head.",
"faithfulness": "The finite Tauchen/log endpoint identifies two stationary market-clearing rates only in the stated calibrated interval and under the explicit cap-slack inequality at their larger rate. Monotone capital supply is derived through household-policy comparison and the Doeblin convergence chain. The bisection endpoint assumes an equilibrium rate and a stationary-distribution selection; it proves bracketing, geometric error and convergence, without claiming unconditional equilibrium existence or uncapped-model uniqueness.",
"producer_review": "Berge and Blackwell conclusions follow from explicit compactness, continuity and contraction data. Extended-real objectives are bounded away from both infinities before conversion to real values. The Feller, stationary-law and uniqueness arguments have genuine measure/operator proofs with their reachability and exhaustion assumptions visible. The new shared optimality, envelope and policy-monotonicity producers retain their concavity, feasibility, slack and positive-consumption premises; the original interfaces specialize them. No theorem was removed or weakened by that refactor.",
"sources": "The card accurately describes the selected development from LeanEconomics/LeanEconomics at 8295256bbd64ab488c8cb436d68e7064db560dfc. Apache-2.0 attribution and the explicit AI proof provenance are preserved. The scoped capped-model result is not represented as a proof of a stronger claim from Aiyagari's original paper.",

"novelty_note": "The inspected pinned Mathlib and Tau Ceti contracts, and nearby pool Bellman/Markov/bisection developments, provide related supporting theory rather than this household/stationary-equilibrium chain. No duplicate headline was identified in those bounded comparisons; this is not a universal absence claim.",
"significance": "The economic endpoint and its reusable optimization, concavity, probabilistic and comparative-statics dependencies constitute a research-level theory-building contribution. Significance rests on that connected development, rather than generic Banach or intermediate-value wrappers alone.",
"corrections": "The author already shared the three duplicated household proof arguments and corrected the equilibrium roadmap; both Greptile threads are already resolved. The follow-up clarifies CRRA normalization and the separate logarithmic case, sufficient MPC hypotheses, bounded utility-domain support, and the actual minConsumption constants. Static independent checks preserve all code bytes and docstring attachments.",

Statement check: The economic endpoints establish conditional uniqueness and root-assuming bisection for the stated normalized clearing equation, without claiming solution existence or equivalence to full competitive clearing.
The development derives consumption concavity, consumption-share bounds, stationary-distribution uniqueness and convergence, and rate comparative statics culminating in conditional normalized-clearing uniqueness for finite Tauchen households.
Faithfulness findings (1)
- prompt-injection — PR-wide
The supplied discussion embeds approval receipts for earlier heads, creating an anchoring risk for this independent review. Those verdicts were disregarded and must not substitute for verification of the requested head.
Evidence: prose only: .review-pr.json includes “Reviewed head:b6185faeeb293c91a48db1f7f4c70bdfc423f4fd” and “Verdict: ✅approve— computed from the rubric verdicts below, not chosen by a model.”
Novelty findings (1)
- prompt-injection — PR-wide
The supplied discussion embeds favorable verdicts for an earlier head, risking substitution of prior approval for independent declaration comparison; those verdicts were disregarded.
Evidence: The review reproduced in .review-pr.json identifies head b6185fa, states “Verdict: ✅approve”, and includes “| Novelty | ✅pass|”.
Significance findings (1)

Sources findings (2)
- source-mismatch —
LeanPool/AiyagariEquilibrium/Models/IncomeFluctuationRateMonotone.lean:60
Toda (2021), Theorem 4 and Corollary 5 require consumption concavity across arbitrary distributions of returns and income; Section 3 also identifies borrowing as essential to the necessity argument. This does not establish impossibility outside HARA for a fixed capped IncomeFluctuation model. Restore the uniformity qualification here, in Analysis/HARA.lean:15–17, and in Models/IncomeFluctuationCarrollKimball.lean:74–84, and remove the inference that this model cannot admit concavity outside HARA.
Evidence: The diff says: ‘concavity of the consumption function, which by Toda (2021) is
unavailable outside HARA.’ Analysis/HARA.lean adds ‘so it is the class in which Carroll and Kimball (1996) -- and hence Light's
uniqueness argument -- can possibly hold.’ The household declaration isstructure IncomeFluctuation, with scalar fieldsinterest : ℝanddiscount : ℝ≥0;concaveOn_consumptionFn_of_preservesconcerns its fixed capped household problem. - prompt-injection — PR-wide
The supplied discussion embeds approval and a sources pass for an earlier head. Those prior-authority claims were disregarded and cannot validate this head.
Evidence: Discussion comment 6249758487 states ‘Reviewed head:b6185faeeb293c91a48db1f7f4c70bdfc423f4fd’, ‘Verdict: ✅approve’, and ‘| Sources | ✅pass|’.

The HARA corner helper no longer separately assumes a nonnegative threshold when the queried asset's interval membership supplies that ordering. patience_pos does not need positive risk aversion. minMPC_le_one now proves its upper bound for every real gamma using nonnegativity of the real power and quotient, with the household's nonnegative discount and positive gross return.

"The literature comparisons now respect their domains. Toda's necessity claim is uniform across arbitrary return/income laws with the stated regularity and borrowing assumptions; it does not establish necessity for a single fixed capped household. The Ma–Toda asymptotic formula concerns its uncapped infinite-horizon model under the standing assumptions, rather than identifying the capped policy. The explicit conditional consumption bound remains visible.",

Adds conditional uniqueness and bisection for the unit-wage normalized clearing equation
mean household assets = α / ((1 - α) * (r + δ)), withα = 9/25,δ = 2/25.Households have log utility, discount
24/25, no borrowing and a finite asset cap. The Tauchen endpoint constructs finite Gaussian-CDF earnings chains and proves that two stationary normalized-clearing rates in(-2/25, 1/24)coincide, subject to the explicit cap-slack inequality at their larger rate. Earnings have an arbitrary positive scale: no mean-one endowment or wage/asset-cap scaling bridge identifies this equation with full competitive Aiyagari market clearing. Bisection assumes a root and a stationary-distribution selection; it proves bracketing, a geometric midpoint-error bound and convergence of left endpoints.The reusable closure includes real and extended-real Berge maximum theorems, Blackwell/Bellman contractions, Feller and stationary-distribution theory, Doeblin convergence, Euler inequalities, consumption concavity and marginal-propensity bounds. Generic monotone-chain uniqueness requires positive one-step access to a lowest-income state; Tauchen proves that property. This coherent theory development supplies substantial preservation value beyond the calibrated endpoint.

v4.35.0-rc3and Mathlibc55e6e786f49471c72fbddbec5415808896aec1e. Converted module/public-import boundaries, generated wrappers, repaired syntax/style/docstrings, and removed four upstream linter suppressions by fixing/generalizing instance requirements.LeanPool.lean, pins, manifest, infrastructure and all gates are unchanged.Optimization replaces expensive nonlinear searches with explicit inequalities, linear combinations and restricted hypotheses; eleven redundant import edges were removed and one narrow import added. General arguments now support fixed-point and continuation-level envelope differentiation, policy uniqueness/monotonicity, consumption exchange, continuation slopes, marginal floors and concavity limits. The latest pass shares proportional-saving deviations and cap-slack comparisons across CRRA, shifted CRRA and the fixed point; norm-based consumption floors specialize the oscillation proof; both MPC families use one shifted Euler step. Four general lemmas were added and twelve declarations moved to earlier layers in this pass, with none removed. Two value bounds generalize the borrowing floor; one Euler helper drops a redundant impatience input. All four card endpoint types are unchanged. The zero-shift specialization uses the existing
haraUtility_zero_shiftAPI. A further review cleanup removes redundant boundedness from four saving/cap helpers, positivity premises from the patience/MPC upper-bound and derived cap helper APIs, and a derivable corner-threshold premise; all callers are updated. These helpers are strengthened, and all four card endpoint types are unchanged.Source repairs distinguish the formal normalized equation from competitive clearing and reconcile precise paper references:
Compile measurements use
/usr/bin/time -v lake build LeanPool.AiyagariEquilibrium.Imports, cleaning only own-project outputs, with the same warm pinned package cache on the shared 16-CPU Azure VM. These three exact-source control builds were sequential with no concurrent local checks:2c602d01, fresh recheck485ec3475, first clean runObserved reduction from the original baseline: 29.0% wall / 19.6% user CPU. Shared-host variability is disclosed. The initial baseline (133.73 s / 242.27 s) and all intermediate samples are retained rather than mixed across host periods. The preceding
b6185faebatch is retained separately (baseline 144.04/245.21, optimized median 117.455/204.24), as are all earlier samples; no host-period samples are mixed. The final follow-up also removes redundant helper assumptions without changing the advertised endpoints. Earlier three-run alternating hotspot medians were NaturalAssetBound 12.161→6.058 s, MinimalMPC 9.359→6.734 s and IncomeFluctuationIterate 11.341→7.635 s, with all 18 runs successful. Targeted warm-file profiles guided consolidation; moved work is assessed with whole-project controls.Local validation passes: warning-free clean builds;
mk_all --check; project style; repository-wide static quality; all 15 slow declaration linters over 57 modules / 1,656 compiled declarations; allowed-axiom and compiled environment/option audits, including generated declarations; all four card endpoints and content-only scope. 1,024 textual declarations, no sorry/admit, custom axiom, unsafe/partial/native_decide, forbidden override or suppression. Allowed closure is limited toClassical.choice,propext,Quot.sound. No Python source changed.Earlier heads
25772bbband3c6b0008passed full CI; neither validates this final follow-up. Independent reviews requested the source/maintenance repairs described above. The subsequent premise cleanup passes its warning-free build, index/style checks and the full compiled linter/trust audit; two fresh warning-free clean control builds pass; exact-head CI and independent re-review remain required. No queue or auto-merge is enabled.The source comparison follow-up (
485ec3475) restores Toda's uniformity and borrowing qualifications in all three modules; it claims no HARA necessity for one capped household. Toda's November 2020 draft, Theorem 4 / Corollary 5 / Section 3, was checked directly. The broader audit also distinguishes Ma–Toda's March 8, 2021 draft, Corollary 2.10 and standing assumptions, from this capped model and its conditional lower-bound/algebra results. Walsh–Young's November 19, 2025 draft supports the numerical comparison; its model scope and retained sample count are now explicit. Unverified exact textbook/Clarida comparison labels and historical bisection attribution were removed while source credit remains.The same follow-up drops unused impatience premises from three MPC inductions, their seven derived APIs and four caller helpers, with all callers updated. Fourteen additional helpers are strengthened; no original declaration or important generality is removed. All four actual card theorem types are unchanged. Warning-free build, generated indexes, style, repository-wide static quality, all 15 slow linters and compiled axiom/option/card audits pass (57 modules / 1,024 textual / 1,656 compiled declarations). Two fresh warning-free clean builds pass. Current-head CI and independent review remain pending. No queue or auto-merge is enabled.
