Draft intake review at 4fc0ab7e543f68ab62c471f2780b05e3bd8f2974.
The exported statements have the advertised finite loopless multigraph scope. LooplessMultigraph assigns an unordered endpoint pair to each independent edge identity, so parallel edges remain distinct. Proper full colorings assign every edge a color in Fin k; ChromaticIndex is the least such k. The density ranges over odd vertex sets of size at least three and counts internal edges with multiplicity. GeneralHighIndexElementary concludes the stated density equality, and the public bound follows without an additional graph or coloring hypothesis. These are statement and definition checks, not a completed review of the entire port.
The complete public inventory is 729 Lean files and one project card, all additions within the content allowlist. Final acceptance remains pending: the final-head aggregate build and warning/linters/trust checks, preservation of the upstream theorem contracts through the final cleanup, the independent project reviews, and normal protected integration. The earlier build, axiom-audit, contract and timing checkpoints in the description are historical author reports and do not establish those final-head results. Profiling remains advisory.
Keep this draft while its published validation work finishes. No queue or auto-merge action is appropriate at this stage.
Additional maintainability feedback at the same head:
In AbsentOwnerReplacement.lean, helperHNcard363Conditions carries the hierarchy, counterexample, prefix constructions and NineN hypotheses into a bound on the union of two optional colors. Its proof uses only the two optional values and generic finite-set/list cardinality bounds, but the caller must supply the larger proof state. This couples a generic fact to unrelated hierarchy details and makes later changes require unnecessary contract and caller edits. Please express the two-Option cardinality bound as a generic lemma and instantiate it here; check the neighboring suffix-membership helper for the same unnecessary context coupling. This is advisory maintainability feedback.
All 730 published bodies and the complete 729-module import graph are now available and checked for identity, coverage and acyclicity. Full proof-port, semantic and current-head validation acceptance remains pending.

Advisory cross-file review against Lean Pool's supervisory rubric. This is not by itself a significance, source-verification, or merge verdict. [Medium impact] No blocking defect was established in the examined repairs, but this partial review does not establish full merge readiness. SummaryImports the Goldberg–Seymour edge-coloring theorem and its high-index equality result. The latest revision shares closed-component, hierarchy-replacement, penultimate-elementarity, and series-cast proofs.

Reviewed published head f1f8c0a82cccbfb8a5ebb4a64bbd14d80c2a1ed3. The PR is now ready for review, so the earlier draft-readiness note is superseded.
The mathematical scope and provenance review is favorable: the finite loopless multigraph model retains independent edge identities and multiplicity, and the final colouring statement uses the full edge domain. I traced the port against the licensed upstream dependency closure, including the explicit-context and hierarchy-predicate reformulations; I found no added mathematical premise that weakens the claimed theorem.
I also reviewed the complete latest two-file delta. The two new Preamble lemmas prove the natural-number bounds already used by the Fin indices. Replacing the arithmetic proof witnesses preserves the index values and assumptions; the other edits rename unused binders to _ while retaining their types. This does not resolve the separate maintainability suggestion in the earlier review, which remains advisory.
This is a source review, with current-head compilation, trust/quality checks and the configured independent review still to qualify. Author-reported local audits and timing results have not been counted as independent validation. Integration must also wait for the applicable current-main checks and normal protected queue.

/review Please review exact current head The hierarchy-coupled utility finding and neighboring cases are repaired: the two-Option cardinality and final-pair membership facts are generic; the first-missing-position fact is generic; duplicate first-position bounds are shared, with an unnecessary finite-vertex assumption removed. The module shrank from 2,877 to 2,193 lines. Controlled focused runs measured 18.310→16.324 s and 2,293,184→2,013,008 KiB peak RSS. The new Mathlib graph interface converts actual vertex/edge sets to types, proves incidence correspondence, preserves parallel-edge identities and isolated vertices, and exposes the bound without requiring finite ambient types. All 730 modules pass the full public aggregate build without warnings, all 15 native linters, compiler diagnostic export (zero), style, static quality/index/card checks, both complete trust audits, and all 506 original upstream theorem contracts. These local observations are tied to the current source hashes. The exact-head clean timing rerun and CI are pending; independent review and protected integration remain separate requirements. |

Reviewed published head 95be6b219559f04be188eba96aeb4a49bf033052.
The new generic two-Option cardinality, final-two-position membership and first-missing-position lemmas address the context-coupling advice in my earlier review. Their callers now supply the facts those lemmas use. The public absent-owner replacement theorem remains unchanged; removing an unused finite-vertex assumption generalizes a private helper.
The Mathlib graph adapter uses the graph’s actual vertex and edge sets, preserving isolated active vertices and distinct parallel-edge identities. Its endpoint/link and incidence correspondence proofs support applying ThmGS to that conversion. The exported bound is stated for the converted graph’s invariants. I also checked the facade, regenerated aggregate and card changes against the complete current source inventory and dependency graph. My source verdict is favorable.
Current-head compilation, trust/quality checks and the configured independent review remain separate requirements. The existing /review request already names this head; older-head checks and author-reported local measurements have not been credited as independent validation. Protected integration still requires the applicable current-main checks and the normal native queue.

Conclusion: approve the source/content at 95be6b219559f04be188eba96aeb4a49bf033052. This is the importing agent’s separate thorough review; it does not replace the configured independent GPT rubric review or authorize integration before that review completes.
The review used the complete local source rather than a truncated patch: all730 files are covered by module/declaration inventories, endpoint signatures, the complete dependency graph, and bounded implementation slices. Foundational graph/coloring/degree/density definitions and176 original data-definition contracts received a separate semantic comparison. All506 original theorem contracts are kernel-proved using the ported declarations. The new graph bridge and the final generic-helper changes were inspected in full.
- Faithfulness:
goldbergSeymourquantifies over arbitrary finite vertex and edge types and every loopless endpoint map. Distinct edge identities retain parallel edges; proper full colorings cover the complete edge domain. Density uses rational division over odd sets of size at least three, with zero included for the empty eligible family.GeneralHighIndexElementarystates the advertised high-index equality. Empty graphs and two-vertex parallel-edge graphs fall within the stated regime. The headline has no undisclosed hierarchy, algorithmic or external-result hypothesis. - Mathlib interface:
graphEndpointPair_eq_iffcharacterizes actual links, andofGraph_incidentproves incidence correspondence. Conversion uses the actual vertex/edge subtypes, including isolated active vertices, so it preserves multiplicity and does not require finite ambient types. The facade exports the bridge and the bound uses the converted graph’s explicitly defined invariants. - Novelty and fit: no existing headline was found in the searched pool cards/source/history/PRs, pinned Mathlib/Tau Ceti combinatorics, or refreshed public code searches. Mathlib’s existing multigraph model motivated the bridge; it is not an existing Goldberg–Seymour proof. Search absence is bounded evidence, not an exhaustive theorem-of-absence. This is completed research-level graph theory with substantial reusable coloring, Kempe, critical-subgraph and Tashkinov infrastructure.
- Sources/license/provenance: the mathematical statement matches Chen–Jing–Zang, arXiv1901.10316v2. The author’s page dates completion October12,2026. Licensed commit88d98c1 explicitly covers Tablet/ under Apache-2.0 and excludes paper/, which is not imported. Wesley Pegden/Trellis attribution and AI provenance are explicit; the new adapter credits Lean Pool contributors.
- Engineering and trust: the hierarchy-coupled Option/cardinality/suffix/first-position helpers are now general facts, and the duplicate first-position bound is shared without an unnecessary finite-vertex assumption.105 repeated arithmetic type witnesses use proved shared bounds. Source budget overrides, diagnostic searches and unstable generated proof references were removed. The full730-module aggregate, all15 native linters, compiler diagnostics (zero), style/index/card/quality checks, both complete trust audits, and506 original contracts pass on matching source hashes. The fixed pool root and all gate/configuration files are unchanged. CI’s Build pool and protected Build project also pass on this head.
Measured cost / quality: 3 of5. The final clean command was LEAN_NUM_THREADS=2 lake build LeanPool.GoldbergSeymour, with private project artifacts removed and exact pinned dependencies warm. Baseline→final:1240.430→1782.543s wall,2019.936→2605.654s child user CPU,282.813→895.614s system CPU,2165628→3407352KiB peak RSS. Whole-project speedup is not established. The shared host was busier;706 modules with identical source and complete project dependency closures had a median1.435 wall-time ratio against the preceding clean checkpoint. That control is descriptive, not a normalized speedup estimate. Focused repairs have measured gains, including39.704→16.457s and6850648→1399832KiB for the shared-index-witness change.
The426,989-line footprint (compatibility baseline224,728) and explicit generated contract plumbing remain real maintenance costs. The interfaces, default-limit proofs, source-strength regression checks and isolated Mathlib adapter make the present source maintainable at the pool’s competent-project bar; this is not a claim of Mathlib-level polish. No further concrete source-blocking finding remains after the repairs. Greptile’s current advisory review reports incomplete full-source coverage, so its green check is not counted as full approval. Independent GPT review and every normal protected native-queue requirement still have to complete.

Statement check: The Lean proves ChromaticIndex G ≤ max (MaximumDegree G + 1) (DensityCeil G) for every finite loopless multigraph, and equality with DensityCeil G under MaximumDegree G + 2 ≤ ChromaticIndex G, using the claimed rational odd-set density and separate parallel-edge identities.

The path-number restriction calculation remains implemented three times: helper_pathLe_1383 here, helper_pathLe_1004 in ChangeLemmaBothOutside/Preparation1.lean:1571, and pathLengthUpperBound in SharedFacts/MixedChangeTransport/Preparation2.lean:724. Their bodies share the same minimum-candidate calculation, including the index transports. Changes to this representation require maintaining three proofs. Extract prefix monotonicity over the actual trees and hierarchies, then redirect all three entry points to it.

Source review at 8b8bd48522f16d020e364500412cd608536aec36 is favorable.
I checked all 22 changed source bodies against 95be6b2, with independent reviews of the shared coloring facts, their callers, and the assembly and terminal-data changes. The concrete maintenance findings from review job2350 are addressed: six certificate-case proofs reuse the existing coloring API; the B/C swap proofs retain their weaker hypotheses through shared present-color lemmas; prefix/minimum-position and component facts replace the repeated local arguments; and the four assembly copies now use one transparent constructor.
The existing public theorem headers and structure fields remain unchanged. The 734-module import graph is closed and acyclic, and the project facade, card, dependency pins and checks are unchanged. The retained source, licensing, provenance, significance and scope decisions still apply; no new mathematical or source-quality finding remains from this delta.
This review does not reproduce the author’s local build, trust audit, environment counts or timings. Current-head compiler, lint, style, quality and other required validation remain separate. The completed CI qualification for 95be6b2 is retained only for that older revision. The existing /review request for this new head needs no duplicate.

Reviewed exact head 45810e743d89ee3d7340b11f426cd9bc57a3a655.
The source review is favorable. I reviewed the complete 94-path refactor, including all 36 new shared-fact modules, with independent checks of contracts, moved proofs, constructors, imports and callers. The card, headline theorems and foundational mathematical structures retain the previously reviewed scope and provenance.
The two quality findings from the 8b8bd485 review are addressed across the cited families: the mixed-change, disjoint-theta and extension branches share proved interfaces; certificate branches use the existing coloringProperties; first-position membership now has an arbitrary-tree lemma without the hierarchy reconstruction premises; and the elementary disjointness cases use general Finset facts. Expanded statement aliases and retained callers preserve the original assumptions and conclusions. The two removed public generated helpers are unused and superseded by the general first-position facts.
I found no remaining source blocker in these changes. This is a source judgment, not a build or performance result: the current-head Lean workflow and canonical check remain pending. The existing current-head five-rubric request is retained; older-head CI and review results do not qualify this revision. Protected integration still requires the independent current-head review, complete applicable CI and current-main/native-queue checks.

At 45810e743d89ee3d7340b11f426cd9bc57a3a655, I checked the published review’s remaining quality findings against the actual source. The four core rubric passes remain separate from the advisory quality result.
The remaining repair is concrete: remove six private TwoTwo forwarders and three private prefix helpers; consolidate ten copied segment, missing-leaf, root-swap and adjoin proofs; and replace broad restoration-context arguments in elementary shared facts with narrow premises. The missing-leaf fact must continue to work without assuming distinct colors, and the root-swap fact must not acquire a proper-coloring assumption. Existing public theorem statements and compatibility wrappers must remain available.
I have prepared this bounded cleanup in an isolated worktree based on this exact head. Independent source checks preserve the existing public contracts; compiler and lint validation is still pending, and the published branch has not been changed. The current head’s complete authored checks are qualified, but queue admission remains pending this source repair and the repaired head’s normal checks and review.

Reviewed published head b3795278cbdd83738da8e985c700590383ba4fc6.
The complete source delta resolves the earlier quality findings: forwarding layers and copied tree/Kempe/adjoin proofs are replaced by shared facts, and prefix/augmentation transport now uses the data it actually needs. I traced the removed helper interfaces to their replacements and checked the surviving consumers. Port-only helper names have been retired; this is not a claim that every old exported helper name remains available.
The forward missing-neighbor fact still needs no distinct-color hypothesis, and the root-color swap fact adds no proper-coloring hypothesis. Removing the unused finiteness premise from augmentation initial-segment transport strengthens that result. The original mathematical statements, graph bridge, project scope, attribution and provenance remain intact. The complete 775-module aggregate is acyclic and contains all project modules.
My source verdict is favorable for this exact revision. Its current-head hosted validation, configured project review and normal protected integration remain separate requirements. The earlier-head checks and my unpublished targeted repair build are not credited to this head.

Reviewed current head 7ddd402ed8237857205a92e9e7ad8a039444ffe4. The source verdict is favorable.
I reviewed the complete 31-path author repair at cc2347e, with independent reviews of the intrinsic tree/prefix facts, certificate transport, exit paths, confinement, stability and their callers. The repeated proof families now use proved data-level interfaces or the existing certified-coloring API. The distinct defective/nondefective no-departure arguments retain their separate justifications. Prefix/order/augmentation facts use the premises their proofs need. The newly shared adjoin fact strengthens the old construction-specific interface.
The retained declaration headers and definition values were checked against the preceding source. Supplemental public port-helper names are retired in this repair; this is not blanket preservation of every previous helper export. All 506 original upstream theorem names remain present, which is written-name coverage rather than a new compiled contract-equivalence claim. The complete 783-module public aggregate is closed and acyclic. The headline mathematics, graph bridge, card, attribution, license and provenance retain their reviewed scope.
I made one small follow-up on the published author commit: removal of the unused private helperRouteToY1012Conditions block and its adjacent blank line. A complete current-project scan found only its declaration. Every retained command, public header, proof body and import in that file is unchanged; the full repository tree change and its inverse were independently verified.
No further source-blocking finding remains from these repairs. The project still has substantial generated plumbing and compilation cost; this verdict is at the pool's competent-project bar, not a claim of Mathlib-level polish or a measured speedup.
This exact new head needs its own complete applicable hosted checks, configured five-rubric review and normal protected native integration. The author’s earlier local validation/timings and successful older-head CI are retained only as dated observations. No new local compiler result is claimed. The current-head configured review was requested once in comment6681345908.

Separate thorough review — exact head Conclusion: request changes. Hosted Lean CI found seven proof-length warnings in five imported modules under current main's compiler check. All three concrete findings in configured review2362 also need repair: repeated closure/cardinality/support/path-adjacency proofs, construction-only premises on elementary hierarchy facts, and two unused private condition interfaces. I inspected the reported source and will repair these directly; these historical observations do not establish merge readiness for later revisions. The independent source audit covers the pinned licensed684-module original theorem closure, every783-module port inventory/dependency graph and endpoint, representative implementation slices, and all32 modules changed since fcc. It includes direct inspection of the six new generic proof modules and the unused-alias deletion. This does not claim manual line-by-line reading of393431 lines. All506 original theorem contracts still recheck in17 batches;154 of176 definition contracts normalize and22 changed/generalized interfaces were individually reviewed. The finite-loopless multigraph bound and high-index equality preserve their advertised assumptions, odd-set multiplicities and actual coloring semantics. The Mathlib bridge retains active/isolated vertices, incidence and independent parallel-edge identities. No algorithmic running-time claim is made. Research significance, source fidelity, eligibility and license remain supported: Chen–Jing–Zang's paper states both results; Wesley Pegden's public Trellis page dates completion2026-10-12; source88d98c1d1a59d1f1bf7c4eb58e73f3945f6daf12 explicitly licenses Tablet/ under Apache-2.0. No paper/ material is included. AI provenance, operation and port attribution are recorded. Pool/history/PR, pinned Mathlib/Tau Ceti and supplementary public searches revealed no duplicate headline. Reusable partial coloring, Kempe-swap, critical-subgraph and Tashkinov infrastructure is preserved. The783-module local public aggregate passes1928 jobs with zero diagnostics under the author-head configuration, as do15 native linters over21748 declarations, style/static/index/card checks, compiled axiom and option/backdoor audits, and original-contract validation on matching source hashes. Hosted test merge59685a9d4 includes current main906301d and its new proof-size compiler plugin; its seven warnings are actual source defects to fix, not a reason to alter any gate. No waiver or configuration change is proposed. Controlled clean measurement at this head:1116.493174s wall,2184.572370s user,301.188318s system,3426772KiB maximum child RSS. Two threads, exact warm external dependencies, cleared private project artifacts and no concurrent acquisition-owned Lean work; shared-host load remains uncontrolled. The original compatibility baseline was1240.429533s/2165628KiB but had4341 warnings and source overrides. The observed final wall difference is−9.99%, peak child RSS+58.23%; this is not a causal speedup estimate. The parentcc checkpoint was1135.119s/3429048KiB. Twelve paired focused profiles include every regression; their after-source and complete owned dependency closures are byte-identical at this head.759 unchanged closures have median final/parent per-file ratio0.974. Compile cost and source volume remain reviewed maintenance tradeoffs. Greptile's current-head advisory reports no blocking defect in the latest deletion and explicitly incomplete full-contribution coverage. Current-head advisory profiling failed during cache restoration with runner disk exhaustion and produced no profile; this is separate from required Lean validation. No queue, auto-merge or merge action has been taken. Approval requires completed source repairs and fresh exact-head checks/review/measurements. |

Exact-head partial-port resolution — The current filename/LOC advisory succeeds and flags16 paths. Every path maps to the actual preserved theorem below and a successful original-statement contract batch on this revision. All506 original theorem contracts recheck in17 batches on the787 current source hashes. This is completeness evidence beyond raw filename or line counts; it does not replace hosted CI or review.
The current source also passes the full1932-job public build with zero warnings,15 native linters over21,682 declarations, style/static/index/card/axiom/option checks and the unchanged main compiler plugin over all787 modules. The new clean whole-project measurement and hosted validation are still running. No merge approval is implied. |

Verdict: request changes — two remaining proof-sharing repairs.
I reviewed the 24-file repair, including the four new modules, their callers, the six condition-value rewrites and the two proof-bearing abbreviation interfaces. The new closure, disjoint-family cardinality, degree-two path, elementary-set and hierarchy facts address the corresponding earlier findings. The removed private helpers have no remaining written references. I found no new mathematical defect in these changes; the retained theorem headers preserve the previously reviewed contracts.
Two concrete parts of the expanded quality review still remain:
-
Nonparallel interchangeability is proved three times. See BaseControl, line 476, ChangeLemmaMixedClosedFinal, line 487, and ChangeLemmaMixedLargestClosed, line 1397. Each reconstructs predecessor stability through the certified SE/RE cases, uses
CertifiedETTRestrictionabove one round, and falls back toTechnicalTheoremBaseat one round. Extract one last-stage interchangeability lemma from the positive-round, maximum-property, lower-round and missing-color assumptions; keep the starred/core identifications as short adapters. The newclosedOfNonParallelshares closure, but does not share this argument. -
The two boundary-return orientations still duplicate the same proof. In ScheideSymmetricOriginalBoundaryAvoidance, lines 110 and 242,
helper_hreturn_one_242andhelper_hreturn_two_319repeat the path-index/maximal-return contradiction withf1/u1/v1andf2/u2/v2exchanged. Parameterize the selected edges/endpoints and the outside/remainder facts, then call one proof from both orientations.
These are bounded maintenance repairs: future changes to the certified-step or return argument should have one proof to update. Please preserve the existing caller conclusions while extracting them.
The seven previously reported proof-length sites have been replaced by canonical APIs or short shared facts. That source change does not itself establish a clean compiler-plugin run: hosted validation of the actual current test merge a94cdcc419c2a47a3995a05d29fc85ffca116d37 remains independent, as do the other required checks and fresh configured review. Earlier-head failures and author-local validation claims are not assigned to this head.

Independent source and engineering review — exact head Conclusion: request changes. Fresh configured review2365 and direct source inspection identify two further repairable engineering findings. The152-line shared-core calculation is recomputed in a branch despite an already available result; substantial outside-advancement, terminal-route and deleted-block proofs are also repeated. Situation/index/transitivity premises remain on five inside-advancement helpers, and two elementary equality helpers retain145-line construction interfaces. These need shared data-level proofs and smaller callers before approval. I reviewed the pinned public upstream, licensed dependency closure, mathematical endpoints and definitions, native Mathlib bridge, complete owned import/declaration inventory, representative source slices and all24 latest changed/new modules. The four new generic proof modules were inspected directly, as were their actual callers and the new elementary-set/hierarchy facts. This is bounded source review of787 modules /390451 lines, not a claim of manual line-by-line reading. The two headlines are faithful: the finite loopless multigraph bound chi' <= max(Delta+1,ceil Gamma), and chi'=ceil Gamma under chi'>=Delta+2. Odd-set density counts internal edge identities with multiplicity over odd sets of size>=3 and includes zero. Proper full colorings define the actual chromatic index. Critical cores and induction contexts are constructed internally, not supplied as extra endpoint premises. The Graph bridge preserves incidence/endpoints, active and isolated vertices and independent parallel-edge identities, including finite active sets with infinite ambient types. No executable or polynomial-time algorithm is claimed. The research-level theorem and substantial partial-coloring/Kempe/Tashkinov infrastructure fit a completed Lean Pool project. The Chen–Jing–Zang source supports both mathematical claims. Wesley Pegden's public Trellis page dates completion2026-10-12 at day precision, within[2026-09-05T10:45:10Z,2026-10-29T10:45:10Z). Public source88d98c1d1a59d1f1bf7c4eb58e73f3945f6daf12 explicitly licenses Tablet/ under Apache-2.0 and excludes paper/, which is not copied. Copyright and formalization/port attribution remain, with accurate AI provenance. Pool cards/source/history/PRs/issues, pinned Mathlib/Tau Ceti and supplementary public searches revealed no matching headline; the public lexical searches are not an exhaustive absence proof. The coherent684-module original theorem closure and useful supporting APIs remain. All506 original theorem contracts recheck in17 current batches. Of176 original definition contracts,154 normalize identically and22 changed/generalized interfaces were individually reviewed. The current filename/LOC advisory's16 paths all map to actual preserved theorems and successful original-contract batches, recorded at #761 (comment) . One card and a generated public wrapper are added; fixed LeanPool.lean is unchanged. The whole diff is content-only, with no gate/config change or waiver. Concurrent author work is retained in the history. The reported substantive proof copies now use actual data-level closure, disjoint-family cardinality, degree-two path and path-number facts. Earlier exit-path, confinement, series stability, prefix/augmentation and hierarchy facts likewise have shared implementations. Construction-only premises are removed from the cited elementary helpers; orphan private condition interfaces and a cycle forwarder are deleted. Expanded proof fields use short canonical proofs rather than duplicated recursors. The latest repair removes2980 net source lines and66 compiled declarations while preserving all original contracts. Short parallel proof patterns and generated context scaffolding remain; this is not a blanket absence-of-duplication claim. Their retained scope is weighed against the new reusable boundaries, complete source/trust checks and measured cost. All11 local check phases pass on787 identical source hashes: complete public aggregate1932jobs/0warnings,15 native linters over21682 declarations, compiler diagnostics/style/static/index/card resolution, complete compiled axiom/option audits and506 original contracts, plus the unchanged current-main compiler proof-size plugin across every owned module. The positive control reproduces the old218-line warning; the current source has zero diagnostics. Axiom closure covers public/private/generated declarations and aliases and allows only the pool's three permitted axioms. There is no sorry/admit, prohibited mechanism, source budget override, suppression or policy weakening. Current clean root:1168.475616s wall,2192.557521s user,305.449157s system,3423920KiB maximum child RSS;779 root modules/1924jobs. Complete public support build:1932jobs/0warnings. Two Lean threads, cleared private artifacts, exact warm dependencies, frozen source and no concurrent acquisition-owned Lean work; other shared-host workloads remain uncontrolled. The parent7ddd checkpoint measured1116.493174s/2184.572370s user/3426772KiB. The original compatibility baseline measured1240.429533s/2165628KiB but emitted4341 warnings and retained source overrides, so was unacceptable content. Current observed wall differs−5.80% from that baseline and+4.66% from the parent; peak child RSS is+58.10% versus the raw baseline.369 unchanged complete dependency closures have median current/parent ratio1.000. No causal overall speedup is claimed. All17 targeted profile pairs pass; every maximum-child-RSS observation falls, while15 wall and12 user-CPU observations rise. Sums80.475→100.803s wall and104.904→106.869s user are disclosed, alongside all individual regressions. The inspected profiles include substantial interpreter/linter work and blocked/unaccounted time. No additional material safe source change is supported by these particular profiles; no causal scheduling attribution is asserted. Direct profiles omit artifact/dependency compilation, unlike the complete root measurement. The local timing configuration is identical to the parent and excludes the new main plugin's overhead; the exact plugin separately passes all787 sources and hosted merged-revision CI enforces it. Hosted test mergea94cdcc41 combines this author head with main775693e4 and the current compiler policy. All10 build shards, assembly, lint/style, repository quality and the Build project context pass. Required minimal-file validation is running after cancellation of only a superseded same-PR extraction; its current check remains required. Main775 merge-group and push Lean validation pass, with individual required contexts success/legitimate skip; refresh before queue entry. Daily asynchronous documentation is not a gate; Documentation preflight remains required. Greptile's current-head advisory reports no blocking defect and explicitly partial full-contribution coverage, not complete merge approval. Advisory profiling42202392868/job127840809765 fails during cache restoration with confirmed runner disk exhaustion and produces no source profile. It is separate from protected validation and the complete local measurements. The earlier repairs and measurements remain valid checkpoints; they do not settle these newly identified maintenance defects. The exact review output is preserved and source repairs are in progress. No queue, auto-merge or merge action has been taken. FINAL CONCLUSION: request changes. Repair the copied core/advancement/route/block proofs and construction-only interfaces, then validate and review the resulting exact head. The current minimal-file check must still pass normally. |

Independent source continuation at 606e50e891cb7da1ec943da61675e90bc780e46a: changes still requested for the two proof-sharing repairs from my preceding review.
The 13-file revision addresses the separate configured-review findings. I checked the four new generic proof modules, their direct callers, the two generalized proposition interfaces, and the shorter equality proofs. The certified terminal-route, deleted-block and tail-swap facts derive the needed results from the existing data; callers do not gain an unproved endpoint assumption. Computing the PE core once and using interchangeability restriction/symmetry also removes the duplicated branch calculation. I found no new mathematical defect in these repairs.
Two independently requested groups remain unchanged and used:
- The nonparallel interchangeability argument still appears in BaseControl:476, MixedClosedFinal:489, and MixedLargestClosed:1399. Share the last-stage interchangeability proof, leaving short starred/core adapters. The new
terminalRouteproves an augmentation route; it does not replace this predecessor-stability/interchangeability argument. - ScheideSymmetricOriginalBoundaryAvoidance:110 and 242 still contains both complete boundary-return contradiction proofs. Parameterize the selected edge/endpoints and outside/remainder facts, then reuse one proof for the two orientations.
All five complete proof commands are byte-identical to the previously reviewed revision; the new helpers do not resolve these two groups indirectly. Preserve the caller conclusions while making those bounded repairs. Current-head hosted CI, configured review, final measurements and author integration custody remain separate; no earlier-head validation or author-local audit claim was assigned to this revision.

Independent review of the new quality findings at 606e50e891cb7da1ec943da61675e90bc780e46a: I confirmed three additional repair groups in the published source.
- Reuse the existing component and advancement results. The local
componentDatainHierarchySituationThreeDisjointThetaUnstoredOutsideImpossiblerepeatsP2905_T2_ElementaryTerminalComponent;TerminalKempeStageSwitchalready demonstrates its adapter. The eligible-indexhelper_tailException_1151repeatsSharedFacts.InsideAdvancement.tailException. The two StoredExceptionhelper_htailEdgesproofs also share the same long tail-color calculation. Extract that common calculation over its actual geometric and coloring inputs, preserving the branch-specific conclusions. - Generalize the two first-missing-position interfaces in
SharedFacts/MixedChangeTransport/Preparation1and remove the duplicated calculations inChangeLemmaMixedLargestClosed.helper_firstLe_1215/helper_firstStrict_1224. Their proofs use only the already constructed tree and coloring.TreeSequenceFirstMissingPositionLeandTreeSequenceFirstMissingPositionMemalready provide the required generic facts. - Share the starred-counterexample construction used in the OneOne/TwoOne Nonexceptional helper contracts. Their repeated elaborated
Eq.mprconstructions obscure the short five-field record already used by the callers. Preserve the exactHStarandgoodStardata and the dependent result types; the whole counterexample record cannot be treated as proof-irrelevant.
The two proof-sharing repairs in my preceding review remain open independently. Please publish the repairs on the author-owned branch and validate the changed dependency cones. I verified these new findings against the current source; configured review2369's completed mathematical passes and the completed Lean CI do not resolve these maintenance requests. Minimal-file validation remains independently pending.

Independent source review of Direct inspection confirms three remaining engineering issues in the published source:
The reported declarations, their callers and existing replacement APIs were inspected in bounded source output. The counterexample-record scan identifies 16 repeated constructions across the two files, including 11 expanded forms. The previously measured revision is frozen before repair; 15 additional before-profiles cover the targeted modules and consumers. These are actionable source repairs and are in progress on the isolated worktree. The complete published source still has its own successful 11-phase local receipt, all 506 original theorem contracts, warning-free public build and completed clean measurement: 1,076.572s wall / 2,152.460s user / 3,433,004KiB maximum child RSS. Hosted Lean validation for this revision succeeded; the independent required minimal-file check is still extracting declarations. These facts do not resolve the maintenance findings above. The next edited revision will require fresh validation and measurements. The mathematical headlines remain the finite loopless-multigraph bound and the disclosed high-index equality, with parallel-edge identities and odd-set density preserved. The Apache-2.0 source grant, attribution, AI provenance, October12 completion evidence and pinned upstream scope remain recorded in the PR. The latest edits have not changed the headline declarations, and their original contracts will be checked again. An older discussion line has also been clarified to name its literal historical revision, preserving its original conclusion and evidence without ambiguous references to a later head. No queue, auto-merge or merge action has been taken. |

Reviewed the published repair at 7c2452ab70a81e0d607ed8ed54dba80ead1d5bbb against the outstanding requests.
The three additional maintenance groups from my preceding review are addressed in this delta:
- The elementary-terminal-component and tail-exception copies now use the existing shared facts.
HierarchyTailColorFactsshares the actual stored-exception tail-color argument; both callers supply the same replacement coloring, hierarchy, last edge and stability hypotheses as before. - The mixed branches use the generic tree-sequence first-missing-position facts, with the unnecessary hierarchy/counterexample setup removed from the helper interfaces.
HierarchyCounterexample.transportreplaces all 16 repeated constructions while retaining the exactHStar,goodStar(including its gamma data), and maximum certificate. The dependent stage/Fin/measure adapters remain in place. Only the proposition-valued positive/non-elementary witnesses are transported.
The two earlier proof-sharing requests still apply at this head. Their five complete helper declarations and proof bodies are unchanged:
- Share the nonparallel interchangeability argument in
BaseControl.lean:476,ChangeLemmaMixedClosedFinal.lean:490andChangeLemmaMixedLargestClosed.lean:1400. - Share the two boundary-return orientations in
ScheideSymmetricOriginalBoundaryAvoidance.lean:110and:242, retaining their existing hypotheses and conclusions.
This is a favorable review of the three repaired groups, with those two earlier requests still outstanding. The four retired MixedChangeTransport first-position helper names and the smaller InsideAdvancement.tailException application interface are deliberate interface changes, rather than a claim that every helper signature is identical. I found no weakened mathematical statement in the reviewed repair.
Fresh validation belongs to this new head. Its CI is still pending; the current plugin audit, clean-build measurements, affected-file profiles and configured review are also still pending in the published author update. Results for 606e50e do not qualify this revision.

Completeness-advisory resolution for
The filename/LOC differences reflect descriptive renames, proof decomposition and reuse of shared facts. The eligible-index module is shorter because its copied tail-exception argument now uses the shared proof. The coherent 684-module upstream theorem closure is preserved. Raw file/line counts alone do not establish completeness; the current declaration, dependency and original-contract audits provide the independent evidence. Hosted validation and source reviews remain separate requirements. |

Reviewed the new completeness and measurement update at 7c2452ab70a81e0d607ed8ed54dba80ead1d5bbb.
The official completeness advisory reports eight unmatched filenames and eight line-count gaps, exactly matching the sixteen rows in the author’s response. All sixteen map to current exported proof commands and their import/decomposition routes. The eight reported current/upstream line-count pairs also reproduce the advisory’s counts. In particular, the short ExtensionBase and HierarchySituationTwoSubcaseThreeOne files delegate to the preserved branch/preparation proofs; the eligible-index bound uses the reviewed shared tail argument. I found no new concrete omission from these sixteen heuristic flags. This is a static counterpart/proof-route review, not a fresh kernel audit of all 506 original contracts.
The displayed measurement arithmetic is correct: all fifteen direct wall/user-CPU pairs are lower, while peak child RSS is lower in ten and higher in five. The complete clean build still shows +24.51% wall and +6.71% user CPU against 606e50e. Direct profiles omit artifact generation/dependency compilation and exclude plugin overhead, so their improvements do not establish a whole-project speedup. The description appropriately records those limits and the shared-host uncertainty; the author’s confirmation run is still pending.
My two proof-sharing requests in the preceding source review remain outstanding. Configured review 2371 is running on this exact head, and the current assembler/Exposition checks remain pending. This follow-up adds no full-CI or merge acceptance.

Separate source review of Direct bounded inspection confirms two remaining engineering families in this published source:
The affected declarations, proof bodies, existing reusable facts and consumers were inspected directly, including the full replacement construction and the restriction branches. The793-module published source is frozen before repair; nine sequential before-profiles cover the affected modules, statement interfaces and the SE/PE consumer. Both clean measurements and all eleven local validation receipts remain preserved for this exact published revision, including506original theorem contracts. Hosted Lean validation42233901116 passes; the independent required minimal-file check42233901176 is still extracting declarations. Neither result resolves the maintenance findings above. Source repairs are in progress in the isolated worktree. Existing boundary and restriction calculations are being shared over their actual inputs; the replacement and projection interfaces will be narrowed without weakening either headline or the original contracts. The next committed source will receive fresh validation, measurements and review. Three older author-summary sentences repeating historical automated rubric endorsements have been removed; their original JSON is archived, and their exact-head source findings, request-changes conclusions and evidence remain. Actual automated review comments were not edited. No queue, auto-merge or merge action has been taken. |

Independently reviewed the new findings from configured review 2371 against the published source 7c2452ab70a81e0d607ed8ed54dba80ead1d5bbb. Its four core rubrics pass; the advisory quality result identifies two concrete maintenance families that I also find need repair.
- In
Step1ZeroDividerAnchorPE.helper_exitBoundary_285(line 27), the result is the existingClosedColorExitPathBoundaryEdgeinstantiated atbase.core; the non-PE branch already calls that theorem at lines 836/839. Reuse it. The PE/non-PEhelper_componentOutside_422/_548proofs should likewise call one confinement fact over the actual tree and two closed colors. Their hierarchy packaging does not change the graph argument. HierarchyCounterexamplePenultimateElementary.helper_branch_111and_216repeat the same predecessor-tree elementarity calculation, includingCertifiedETTRestriction ... (ett.rounds - 1). Share that calculation using the actual maximum/lower-round and index hypotheses, retaining the distinct SE selected-color and RE identity-color transports afterward.ChangeLemmaMixedClosedFinal.helper_replacement_855andChangeLemmaMixedLargestClosed.helper_replacement_1032contain a byte-identical 62-line nonparallel construction (lines 1109–1170 / 2306–2367). Share the correspondence-to-base/hierarchy construction and call it from both branches. Preserve the actual support-position cast andHB.dividerCount,HB.stage, andHB.dividerPosition: laterSameHierarchyStagesand gamma/goodness consumers depend on these data. The parallel closure-containment and later index-dependent arguments retain real differences. A proof-irrelevance shortcut would not establish the required data agreement.- The three revisiting projection/agreement helpers in
TdTerminalRERebuild(5482/5518/5660) expose the large contracts inRevisitingTerminalStatementsand forward return-walk/cycle/crossing assumptions at their callers. Yet the penultimate-tree calculation iscastSeriesTree,hextendedData, append projection, andhreplacementCurrentTree; the data/tree agreements additionally use the corresponding actual prefix/field agreements. Extract those facts over their real series, rounds and field equalities and narrow the callers. The final-tree/final-color calculations inTerminalSeriesRebuildTransport(817–824 / 3597–3604 and 914–922 / 3695–3703) are also literal copies under larger construction contexts. Keep certificate validity at the construction boundary where it is needed, and preserve the seven existing public contracts as compatibility wrappers while routing downstream callers through the narrower shared facts.
These copies can drift independently when a transport or reconstruction changes, and the oversized projection contracts force unrelated construction details through every caller. The requested repair is shared proofs and smaller real interfaces, preserving the original mathematical contracts and selected hierarchy data. This scoped inspection found no mathematical counterexample.
The author's new source-review/repair update is consistent with this diagnosis; final source custody remains with that repair work. My two earlier outstanding proof-sharing requests also remain. The current core Lean workflow has passed, while the required minimal-file check was still pending at the inspected cut. This review grants neither full-CI nor merge acceptance.

Filename/LOC advisory resolution for exact head The advisory completed successfully with16heuristic flags. Every flagged upstream endpoint remains present under its recorded name mapping and rechecks against its original theorem contract. All506original theorem contracts pass on the identical797source hashes. Proof splitting, descriptive renames and shared facts explain the filename/LOC differences; file counts alone are not completeness evidence.
The required Lean and minimal-file workflows remain independent checks. No queue or merge action has been taken. |

Reviewed the published source at b2910bf5f87c1a28477584ae35646d2adb0e2d30, including all 17 changed/new files, the four new shared APIs, their actual consumers, and the unchanged sites of my earlier requests.
The repairs to the two maintenance families in my preceding review are favorable. The component-confinement and penultimate-elementarity proofs now use their actual graph/closed-color or maximum/lower-round hypotheses. StableHierarchyReplacement shares the construction while preserving the support-position cast, hierarchy stages/dividers and the gamma/goodness data used afterward. The cast/prefix APIs preserve the seven old mathematical conclusions from the same inputs and keep certification at the construction boundary. The retired plumbing names are not externally name-compatible wrappers; their current callers use the more general facts, and this inspection found no lost upstream declaration or mathematical counterexample.
Two earlier proof-sharing requests remain at this exact head:
- Share the nonparallel interchangeability argument in
BaseControl.helper_nonPEInter_586(line 476),ChangeLemmaMixedClosedFinal.helper_branch_399(492), andChangeLemmaMixedLargestClosed.helper_branch_568(1402). These complete proof copies remain unchanged and are still called at 1169, 1093 and 3040 respectively. The new hierarchy-replacement factory addresses a different construction. - Share the two boundary-return orientations in
ScheideSymmetricOriginalBoundaryAvoidance.helper_hreturn_one_242/helper_hreturn_two_319(110/242), retaining their actual orientation and return hypotheses. Both proofs and their calls at 833/837 remain unchanged.
The 16 completeness-advisory flags still establish no concrete omission: the named endpoints and their current import routes are present. This is bounded source inspection, not an independent kernel equivalence check of all 506 claimed original theorem contracts or a line-by-line review of all 797 modules.
The description now correctly distinguishes the historical 606e50e89 measurement from both 7c2452ab70 observations. The new published clean result is 1677.046s wall / 2433.007s user CPU / 3,428,496KiB maximum child RSS; the reported 10 module pairs have lower wall/user/RSS observations in 4/7/9 cases. These shared-host observations warrant the author's ongoing parent-control investigation but do not establish a causal speedup or slowdown. I have not inspected private measurement or local-validation receipts.
The new source is bound to the actual CI checkout 516a0ac6 and its complete Plan; full current-head CI and the fresh configured review remain pending. No result from the previous head is substituted. Please complete the two remaining source-sharing repairs under the existing author custody; this review does not grant queue or merge acceptance.

Separate source review of Direct source inspection confirms four engineering families requiring repair:
The complete hosted Lean validation42257660581 succeeds, and all11local phases, the complete zero-diagnostic root/public build,506original theorem contracts, source inventories and measurements are preserved for this exact head. The independent required minimal-file check remains in progress. These checks do not resolve the maintenance findings. All797source files are frozen before the next repair. The primary current-head measurement and all paired profiles are retained, along with a byte-verified contemporaneous parent control. Eleven targeted before-profile baselines cover the next repair: seven observations from the identical complete source state and four fresh executions. Every regression remains recorded. A scratch-only record-assembly experiment failed compilation and was not applied. Main has separately advanced to49bdad2b2 with warningAsError=true. Its policy changes have been read, its Lean validation is pending, and the author branch has not been updated merely to follow main. Source repairs will receive fresh current-head checks, measurements and reviews. No queue or merge action has been taken. |

I independently checked the four quality findings in configured review2372 against the published source at b2910bf5f87c1a28477584ae35646d2adb0e2d30, including their actual callers. All four identify bounded maintenance repairs; none establishes a mathematical counterexample.
- Path-number restriction:
ChangeLemmaMixedLargestClosed.helper_pathLe_1383(2871),ChangeLemmaBothOutside/Preparation1.helper_pathLe_1004(1571), andSharedFacts/MixedChangeTransport/Preparation2.pathLengthUpperBound(724) repeat the same finite-candidate minimum argument and index transports. Extract one prefix-monotonicity fact over the actual trees/hierarchies and redirect all three entry points. Keep the real initial-segment, last-star equality and length hypotheses; the separate lexicographic/minimal-counterexample argument remains in the callers. - Missing-neighbor and component arguments: reuse
TwoColorMissingVertexNeighborsSubsingletonin the twoStep1ZeroDividerAnchor*finish proofs andHierarchyCounterexampleOneAdditionPositiveDividerImpossible.helper_missingLeaf_1742. The existing theorem needs proper coloring and the missing-color disjunction, without those construction-specific premises. Share the subsequent three-distinct-leaves/two-endpoints component contradiction between the anchors. Preserve the actual tree membership, exit paths and interchangeability; the PE-specific derivation of interchangeability stays with its real maximum/lower-round/stability hypotheses. - Fixed-root interfaces: narrow the six private helpers in
AlgorithmFiveSixFixedRootRefresh(helper_hcarry_334,helper_hprecedingV_354,helper_hstarV_360,helper_hnewStoredV_366,helper_branch_397,helper_branch_404). Their introduced originalbaseandgoodarguments are unused afterward. Keep the actual hierarchies, count equalities, field agreements and Fin transports. The caller'sgoodV/goodWgamma data are still used and must remain. The adjacent initial-segment proof can useTreeSequenceInitialSegment.trans. - Terminal cast scaffolding:
TdTerminalSEPERebuild.helper_continuation_1015andhelper_continuation_1218only introducecastSeriesStored/Edges/Kind, while their callers still construct and pass all three. Narrow the private Conditions and applications together, then remove the orphan constructions and unused raw-index/final-color/final-tree witnesses. Use the canonical cast/projection facts for the remaining adapters. In the RE and other transport adapters, some callbacks and final witnesses are actually passed onward: canonicalize their downstream interfaces before removing them. Preserve the distinct SE/PE/RE branch metadata, replacement input, prefix agreement and stability.
These four groups are separate from the two outstanding groups in my preceding review: the nonparallel-interchangeability copies in BaseControl/MixedClosed/MixedLargest, and the two boundary-return orientations. There are therefore six outstanding source-repair groups at this head. Subsidiary neighbor reuse/transitivity/dead-witness steps are included in the four groups above, rather than counted again.
The factory, certification and same-input cast conclusions accepted in my preceding review remain favorable. This update concerns current proof organization and interfaces; it does not reopen those repaired facts or claim a full independent kernel comparison of all imported theorem contracts.
The official five-rubric report is complete at this exact head, despite the description's older “running” wording. Its advisory score is not a separate human-policy gate. The author's published acknowledgment retains repair custody; please publish the bounded repairs and validate the resulting head. Current CI and protected integration remain independent requirements.
Preserve the completed Goldberg–Seymour theorem for finite loopless multigraphs, with independently identified parallel edges:
ChromaticIndex G ≤ max (MaximumDegree G + 1) (DensityCeil G).The import also proves
ChromaticIndex G = DensityCeil GwhenMaximumDegree G + 2 ≤ ChromaticIndex G. Odd-set density is the maximum of zero and internal-edge density over odd vertex sets of size at least three, counting parallel edges separately. It claims these mathematical results, without claiming an executable or polynomial-time coloring algorithm.Source, eligibility and license

Scope and engineering
Preserves the coherent upstream theorem closure of 684 source modules and reusable partial coloring, Kempe components, critical subgraphs, Tashkinov trees, certified extension sequences and good hierarchies. Current scope: 797 modules / 383,626 physical lines / 3,431 import edges; root closure 789, plus public supporting APIs.
The Mathlib

56a005855ea17e0b0958f73ec801ae140b0a1679. Adds one YAML card and generates its publicImports.lean; fixedLeanPool.leanremains unchanged. Content-only diff. No workflow, gate or linter-configuration changes; no raised proof limit, suppression or waiver is added.Porting repairs cover version-sensitive APIs, typed witnesses, canonical proofs and closed proof continuations. Earlier optimization shares tree-prefix/order, walk-confinement, series-stability, hierarchy-nesting, coloring-transport, disjoint-family cardinality, degree-two path and path-number facts, and removes repeated expanded terms and seven current-policy oversized proof sites.
This revision addresses the remaining duplicated proof and series-projection interfaces:
rfl.All 17 latest changed/new modules were reviewed in bounded output; the four new mathematical APIs were inspected in full. This revision removes 3,906 net physical source lines relative to frozen parent7c2452ab70.
Theorem strength and useful generality are preserved. All 506 original theorem contracts recheck in 17 batches. Of 176 original definition contracts,154 normalize identically and22 changed/generalized interfaces were individually reviewed. Axiom/option audits include public/private/generated declarations and aliases. No sorry/admit, prohibited axiom/mechanism or theorem weakening.
Validation at
b2910bf5f87c1a28477584ae35646d2adb0e2d30All 11 local phases pass on identical hashes for all 797 owned sources: complete public aggregate with zero warnings,15 native linters, compiler diagnostics, style/static quality, generated indexes/card resolution, full axiom/option audits, all 506 original contracts.
Current compiler-policy audit: 797 modules, zero diagnostics: 160 fresh direct compiler executions and 637 explicitly recorded reuses of byte-identical complete owned import closures under exact unchanged external pins, compiler options, toolchain and plugin binary. Parent timings remain parent observations. The local author Lake configuration excludes the plugin newly added on main; it is separately validated with explicit complete-closure caching under unchanged pins/options/plugin, and enforced in hosted merged-revision CI. Plugin overhead is not included in the paired timings.
Configuration detail: Current primary/frozen-parent control use identical author config, excluding later-main compiler plugin and warning-promotion option. Exact unchanged plugin separately validates all797sources (160fresh/637exactcomplete-closure reuse), with zero diagnostics; hosted prior-main testmerge passes. Newmainwarningpromotion is enforced by normal nativequeue, and no newmain success is claimed. Control overlaps configuredreviewservice on sharedVM; workload effects uncontrolled.
Bounded review covers all 797 module endpoints, dependency closure and representative implementation slices. All17 latest changed/new modules were inspected, including the complete newly generalized proofs; no manual line-by-line claim over the entire project.

Measured compilation
Clean command:
LEAN_NUM_THREADS=2 lake build LeanPool.GoldbergSeymour, deleting only the isolated worktree's private.lake/build, exact warm dependencies and frozen source. No other operator-run Lean job accompanied the current primary measurement. The later frozen-parent control overlaps the configured review service, with its resource use uncontrolled. Shared VM with 16 CPUs; unrelated workloads are uncontrolled. Commands, source hashes, complete resource records and per-file observations remain on the operator VM.Original compatibility baseline: 1240.430s wall / 2019.936s user / 282.813s system / 2,165,628KiB maximum child RSS, 685 sources / 224,728 lines. Its 4,341 warnings and budget overrides made it unacceptable incoming content. Retained historical checkpoints: fcc1001.043s/3,435,456KiB; cc1135.119s/3,429,048KiB;7ddd1116.493s/3,426,772KiB;0531168.476s/3,423,920KiB. Checkpoint606e50e89 measured 1076.572s wall / 2152.460s user / 304.318s system / 3,433,004KiB maximum child RSS, 791 sources / 389,610 lines. The immediate frozen parent7c2452ab70 primary measured 1340.425s wall / 2296.844s user / 329.217s system / 3,426,468KiB maximum child RSS; its identical-source confirmation measured 1090.251s wall / 2146.160s user / 319.795s system / 3,425,612KiB RSS, 793 sources / 387,532 lines. Both parent observations are retained; the repeat does not replace the primary or causally normalize shared-host variation. These are separately labeled revisions. Larger explicit interfaces and peak memory relative to the compatibility baseline remain maintenance costs.
Current-head clean root: 1677.046s wall / 2433.007s user / 339.079s system CPU / 3,428,496KiB maximum child RSS. Load 46.41→47.69. Relative to parent7c2452ab70’s retained repeat, observed wall +53.82%, user CPU +13.37%, maximum child RSS +0.08%. Relative to the original compatibility baseline, observed wall +35.20% and RSS +58.31%. These shared-host observations are not causal speedup estimates. Identical complete source/dependency closures: 632, median current/parent rounded per-file wall ratio 1.345; descriptive only, without normalization. A contemporaneous clean frozen-parent control is in progress under the current shared-host conditions to investigate the whole-build regression; no causal conclusion is claimed. The current primary result and both earlier parent measurements remain unchanged.
Ten pairs compare frozen 7c2452a with this source, sequentially, with two threads and warm exact external dependencies. Owned closures change and shared-host load is uncontrolled. Lower observations: wall 4/10, user CPU 7/10, peak child RSS 9/10. All regressions remain in the table.
Direct profiles use
lake env lean --profile --setup, omit artifact output and dependency compilation. Whole Lake builds include artifact generation and dependencies. Focused improvements do not establish a whole-project speedup.Integration uses the protected native ALLGREEN/SQUASH queue only after current-head checks, applicable current-main validation and resolved reviews. Required contexts are inspected individually. Daily asynchronous documentation and advisory profiling are not merge gates; Documentation preflight and every other applicable protected check remain required. No deployed-documentation announcement is made.
