feat(ThreeSum): prove conservative native subquadratic execution - #2159
Conversation
Adapt the finite counting interface and signed digit expansion from anthropics/formal-math@16a5ce4 for milestone #1438. This is a mathematical interface; native preprocessing, fast solvers and full composition remain under #1394.
Adapt the complete finite Theorem 17 splitting and recovery component, using the existing three weight matrices, lopsided graphs, modular counts and EqOn answer interface. Prove exact integer/real capacity bridges so the finite constructions and scans are computable. Preserve Anthropic source credit; keep the native 3SUM endpoint open in #1394. Validation: all six gates in scripts/check.sh pass, with LEAN_NUM_THREADS=1 and cache downloads disabled after bootstrap. Full hygiene, changed-source check-simp, changed-file lints and git diff --check pass. Curated abstracts and rendering are unaffected. AI-assisted implementation/self-review by Codex worker codex-three-sum-splitting-t3-0a4d90c0; independent review will be recorded in the PR.
Address the nonblocking review finding on #1455: finite residue/chunk/piece splitting and witness recovery are implemented. Preserve native preprocessing, fast solvers, full input/time/width composition and exponent 1.9992 as open work under #1394. Documentation only. Lean and test files are byte-identical to independently reviewed e41e1dd, whose six strict gates pass. Checked the diff, milestone reference, implementation paths, hygiene and changed-file lints. Abstracts and rendering are unaffected.
Implement fixed native residue, histogram and composed collision-counting programs with explicit frames, local word-fit contracts, exact mathematical collision semantics and charged bound 34n + 5M + 18 (halt excluded). Implementation layer for #1454 under #1446/#1394, not full preprocessing. Sorting/frontend, prime searches, heavy extraction, recursion/output and global logarithmic-width/subquadratic-time composition remain open. Curated abstracts: no impact on headline statements, definitions or scope. Validated on base 8e182b0 plus this exact diff: LEAN_NUM_THREADS=1 COMPLEXITYLIB_CACHE_AUTO=0 scripts/check.sh: all six gates passed, including strict test/global axiom audit. Changed-file lints against that base, hygiene --check-simp and git diff --check passed. Final run followed resolution of shared-host disk/memory pressure; failed earlier attempts are not counted as validation. Independent read-only agent correctness/API review by /root/review_native_histogram approved the final source blobs after replacing three private clear helpers with WordRAM.clear. No remaining blockers; optional Count parameter-frame API can accompany its minimum-search client. This is within-fleet agent review, not outside-coordinator or human approval. Outside coordinator review is required before integration. AI assistance: OpenAI Codex implementation/self-review and a separate Codex review context. Native programs/counting proofs are original; existing Anthropic mathematical source credit is preserved unchanged.
Implement the complete finite mathematical milestone of #1463 above #1464: valid layouts, batch-product correctness/error exclusion, arbitrary-N tiling, exact requested signed products, order/cardinality estimates, geometric tails and the derived sparse bounds. At D=4^m, L=19m, D^18<=N and |W|*2^m<=N^2, encoding entries are bounded by4*N^2/D^(1/18), contributing leaves by33 and passed-set cardinalities by(19m+1)*33 times that scale. Add finite magnitude and auxiliary object-count bounds. None are native instruction costs. All six final local gates pass: strict build, aggregate check, strict tests, environment lint, style lint and init-import check. Hygiene --check-simp, changed-file lints (14 library modules,1 new test) and diff --check pass. Tests kernel-check signed results3,20,0,-8, true padding, empty/sparse and negative-order boundaries, and instantiate all aggregate bounds with jointly satisfiable m=1 parameters and symbolic matrices without resource overrides. Read-only math/API review by /root/thin_product_review is clear after fixed doc references/magnitude wording/quotation hygiene. Focused final delta review by /root/thin_product_final_delta_review is clear for tree b021e2d, reusing the prior mathematics review. These are internal agent reviews, not outside coordinator or human approval. Source: anthropics/formal-math@16a5ce4, selective Section2 finite mathematics; Anthropic credit/NOTICE retained. Abstract assessment: no impact on selected headlines, catalogue or rendering. Full native tensor/sparse-product/Exact Triangle code, native Chan-He #1446, whole input/time/width composition and improved1.9992 remain under #1394. AI assistance: implementation and reviews with OpenAI Codex, worker session codex-thin-product-math-20261028.
Implement fixed 24-register parameter code with charged numeric helpers, exact existing Chan–He outputs, preserved input memory, derived logarithmic width and subquadratic native time. Add executed boundary and input-init contract examples. Original implementation and proofs credited to Erik Demaine; AI assistance by OpenAI Codex. Part of #1446; independent complete parameter subtask #1458.
Restack #1463 above repaired #1464 without changing the reviewed mathematics. Rewrite 149 documentation blocks in 14 modules as standalone descriptions; replace operation-cost and word-size narratives with the exact entry, leaf, passed-set and specified-value quantities proved. Preserve pinned Anthropic credit, source locators, statements, definitions, proof bodies and imports. An independent comparison with original ee288fb confirms that all code bytes outside comments are identical, including code whitespace. Validation of this final tree: all six gates pass together (strict build, aggregate check, strict tests, environment lint, style lint, init imports). Citation-aware full hygiene --check-simp, changed-file lints (14 library modules, one test) and git diff --check pass. Lean MCP FiniteMagnitude diagnostics finish without errors or warnings. Serial Smoke/Axioms warmups avoid the shared-host memory failure previously seen when these import-heavy clients run together. Tests and substantive math/API review evidence are retained from the original reviewed tree b021e2d in ee288fb. This change is documentation-only; /root/draft_thin_docs authored the scratch map and the continuation worker inspected/applied it. That drafting is not independent review. Earlier math reviews are inside-fleet agent reviews, not outside or human approval. Outside coordinator review will be requested on the final PR. No selected abstract, catalogue or rendering is affected. PR publication remains held while native dependent restacks are repaired, per root sequencing. #1394 remains open: native shared encodings/pruning/Exact Triangle, Chan-He #1446, complete Convolution/ordinary input/time/width composition and the improved Section4 route to exponent1.9992 are not supplied by these finite counts. AI assistance: OpenAI Codex workers codex-thin-product-math-20261028, codex-three-sum-continuation-t3-3dda8289 and /root/draft_thin_docs.
Complete the shared left/right encoder milestone #1493 above parent b4936ce (#1496). Fixed standard-WordRAM code with 32 registers computes every public encodingL/encodingR leaf from actual initialized flat signed inputs. The native bound is 240*(L+1)*10^L instructions plus halt, with explicit magnitude/address inequalities, two alternating buffers, charged initialization/copying and the complete outside frame. The full ordinary native 3SUM objective #1394 remains open; this component supplies no sparse-query or Exact Triangle solver. Validation of tree b598513 against b4936ce: all six gates pass together (build --wfail --iofail, mk_all --check, test --wfail --iofail, lint, lint-style, checkInitImports), full citation-aware hygiene --check-simp, changed-file lints (13 library modules, one new test) and diff checks pass. Tests execute both encoders at depths zero, one and two, compare all 100 depth-two leaves with the unchanged public encodings, preserve input/frame sentinels, and cover adjacent word widths and all three copy block orders. Kernel-checked concrete flat executions discharge every width/magnitude premise. Selected abstracts, catalogue and rendering are unaffected. AI assistance: OpenAI Codex implementation and self-review by delegated worker codex-shared-encoding-t3-03b600bd. Independent correctness/API review is pending; this is not an approval or a claim that the complete 3SUM objective is done.
Connect the zero-depth and two-stage regression memory witnesses to the actual prefix Runs already proved by runs_left, rather than discarding that conjunct. Bound the prefixes by 240 and 72000 instructions and expose the same executions' charged halt at n+1. All library code is unchanged from ad3e097 (tree b598513). Validation of tree 8277017 against actual parent b4936ce: all six gates pass together (build --wfail --iofail, mk_all --check, test --wfail --iofail, lint, lint-style, checkInitImports), full citation-aware hygiene --check-simp, fresh changed-file lints (13 library modules, one test), strict PR-draft declaration-name check and staged/unstaged diff checks pass. Independent nonauthor agent review 8034f3da approved exact ad3e097/tree b598513, covering full code/model/cost/width/source and ArrayCopy with no blockers. It is inside-fleet review, not outside approval. This test-only delta addresses its optional witness-connection finding; focused final test/source-mapping review remains pending through the parent coordinator. No selected abstract, catalogue or rendering impact. The full ordinary native 3SUM objective #1394 remains open; this implements encoder issue #1493. AI assistance: OpenAI Codex implementation/self-review by delegated worker codex-shared-encoding-t3-03b600bd. Publication remains on hold for focused review; this commit is not approval or a whole-3SUM completion claim.
Work in progress for #1526. Fixed native controller and initialized-input interpreter regressions, numerical child-set bridge, call-count potential, charged power/scan/clear/frame/arithmetic/return kernels. Individual current Lean modules have clean MCP diagnostics; the earlier strict targeted scan/count/value/test checkpoint passed. The complete global controller invariant, native evaluator theorem, actual initialized flat-run clients and sparse charged bound remain unfinished. No full six-gate or independent review claim; no PR submission. Full #1394 endpoint remains open. AI-assisted implementation by codex-three-sum-continuation-t3-3dda8289.
Address the bounded nonblocking review findings on #1496. Keep Nat.choose_le_exp_mul_div_pow unchanged while deriving it from Cslib.sum_choose_le_exp_one_mul_div_pow in the existing real binomial module; remove the redundant module and migrate its import. Preserve Anthropic, Samuel Schlesinger, OpenAI and Erik Demaine credit. Kernel-check an actual mixed inner/outer L2,m1 signed pruned result of -8, remove two signature-only tests and retain positive admitted-parameter checks. Paraphrase the identified source-derived sentence, shorten generic source boilerplate and record the generic naming follow-up. No public mathematical statement or definition changes meaning; no selected abstract or endpoint promotion. Final validation/source/review evidence is in PR #1496. AI-assisted implementation by codex-three-sum-continuation-t3-3dda8289.
Implement the complete bounded #1523 native component under #1394. A fixed 96-register standard WordRAM program computes valid subset/inverse tables and a deterministic existing Layout, prepares all padded signed row/column bands, calls the unchanged #1520 encoders once per shared band, collects every leaf, and restores the entire initialized input prefix and outside frame. The State.init and flat Runs/Executes clients bind the actual output memory to public encodingL/R in the unchanged leafIndex order (P0 digit 9). All powers, mask/popcount/root/table loops, indices, guarded matrix addresses, initialization, copying, encoder calls, loop controls and halt are charged. The generic bound is 4096*(L+1)*(1+N*4^m+2^L+2*numBands*10^L), plus halt; at L=19m and N>=(4^m)^18, the full charged run is <=81920*(L+1)*N^2/(4^m)^(1/18). Width assumptions are explicit original-parameter inequalities: the wordBudget fits target w+2 and 7^L*A < 2^(w-1), w>0, A>=0. Actual signed kernels use at most 15/17 instructions for add/subtract, already included through the unchanged encoder's real cost. No all-state fit, callback, solver, assumed run/cost or source machine semantics is a hypothesis. Symbolic positive-depth thin native examples and concrete signed/padded/frame/width-boundary executions establish nonvacuity. Pinned source: anthropics/formal-math@16a5ce4, 3sum-apsp/ThreeSumApsp/Programs/Sec2/Theorem5/Encode/AllBands.lean:230-239,262-271 and BandArrayFacts.lean:107-113. Verified checkout files equal their pinned Git blobs and all PR-draft quotations match those exact line slices. The source's row/column encoding predicates map to runs' quantified original matrices, all bands and all leaves on computed MaskTable.layout; Light limits/program maps, callee contracts and source time hypotheses are replaced by actual native code proofs, not imported. The block index is beta*K0+(side? h:g), and row is block*N0 plus the compressed outer offset. Shared tile pointers and retained table words are exposed by tileInputBases/tile_input_values/table_word_layout. Reuse unchanged WordRAM control/rename/copy/signed APIs, Layout/bandArray/encoding mathematics and Mathlib finite index/sorted-set APIs. New mask scans, dense inverse lookup, direct base-seven decoder and native execution/cost composition are original. Small native-power/ordered-filter/positional-digit/row-major lemmas live in narrow topic modules. Retain Anthropic, PBC source credit and NOTICE. Validation: PASS all six strict gates (build --wfail --iofail, mk_all --check, test --wfail --iofail, lint, lint-style, checkInitImports), serial Smoke/Axioms warmups and the global Axioms audit; full citation-aware hygiene --check-simp, fresh actual-base changed-file lints, strict PR-name and diff checks. Validated with LEAN_NUM_THREADS=1 and cache downloads disabled. Windows static metadata reads used PYTHONUTF8=1; no Lean/source change was needed. New Lean files use ordinary non-executable file modes. Exact payload tree bdfc5a1. Targeted Lean MCP endpoint/tests and pinned quote identity also pass. No PR has been opened; independent exact-revision correctness/API/source-mapping review is pending. Abstract assessment: no impact on selected abstracts, models or scope; no new headline or PDFs. Pruned queries, products, solvers and whole ordinary 3SUM remain open under #1394. Base #1520 remains unchanged at 3b9234d. AI assistance: Codex implementation/proofs, session codex-native-bandprep-t3-03b600bd, under delegating-worker coordination. Existing unchanged encoder outside-review evidence is PR1520#issuecomment-6477077023; final new-component review pending.
…tions Work in progress for #1526, not a submitted component. Complete native parent accumulation loop (31N+3), internal sparse initialization (7N+8), computed child push (15), shared actual frame-word store, executable query-code inverse/requested-set bridge and recursive timestamp allowance. These current modules have clean targeted Lean MCP diagnostics; actual interpreter and kernel digit/request regressions pass. Changed-scope hygiene --check-simp and diff check pass. The general node/controller continuation proof, actual initialized full evaluator theorem and final sparse charged bound remain unfinished; no full six-gate or independent review claim. AI-assisted implementation by codex-three-sum-continuation-t3-3dda8289; full #1394 remains open. Final current-tree checkpoint: strict build --wfail --iofail of Accumulate, Clear, Push, Frame, Powers, Leaf, Weight, Scan and SchonhagePruned tests passed together (3596 jobs); scope hygiene --check-simp and diff checks pass. This is a partial implementation checkpoint, not an all-six-validated PR or completed #1526 milestone.
WIP #1526. Factor root scan setup and root finish; prove the actual eleven-instruction root-frame initialization and exact memory/register frame. Current Root MCP diagnostics clean. Full node/controller composition remains unfinished; no PR or full-six claim. AI-assisted continuation by codex-three-sum-continuation-t3-3dda8289.
Address the sole P2 finding from the independent #1523 review of cb261f6: remove duplicate Nat.ofDigits_ofFn and publicly import the existing radix module. The finite-function numbering bridge uses Nat.ofDigits_ofFn_eq_sum. Its statement is unchanged. Existing radix declarations, proofs and source credit are unchanged; no native program, endpoint statement or test changed. Validation on exact final tree 4807cb9: PASS all six strict gates together (build --wfail --iofail, mk_all --check, test --wfail --iofail including global Axioms, lint, lint-style, checkInitImports), fresh actual-base changed-module lints (29 library/1 test), full citation-aware hygiene --check-simp, strict draft-name and diff checks. Serial LEAN_NUM_THREADS=1; optional cache downloads disabled. Lean MCP also reports clean diagnostics for the changed bridge. Logs are in .lake/codex-three-sum-continuation/band-review-six in the continuation checkout. Original native implementation and all full correctness/API/source-mapping review coverage retained. Review record: #1523 (comment) Original implementation/validation handoff: #1523 (comment) Focused final delta review pending before PR publication. No impact on selected abstracts, models or scope; no new headline. Complete #1394 native 1.9992 endpoint remains open. AI assistance: bounded reuse fix and validation by Codex session codex-three-sum-continuation-t3-3dda8289. Original author credit remains on cb261f6.
Continue #1526 implementation under #1394; this is explicitly partial WIP, not a complete component or PR submission. Full recursive node composition, initialized input/flat clients, derived global fits and total-time theorem remain open. No solver or all-state fit/execution/time certificate is assumed. Check full root setup/scan/frame (20Q+19), report (9Q+3), leaf/return (24), loaded leaf step (43), internal entry (7N+28), native nonempty child scan/push (20N+42), empty-child scan/advance (20N+33), returned-child accumulation (31N+29), and final return (26) against the actual standard fixed native Code. KernelRegs describes only constant/pointer register values. Node footprints preserve the ancestor rows. The zero-depth node matches existing Pruned.result and the finite traceWeight; its continuation uses the existing ExecWithin.loop_iter. No alternative machine or run semantics is introduced. The reporting-body/controller names are definitionally identical Code trees. ScanMemory.congr transports the existing representation across disjoint writes and removes duplicate root proof plumbing; push exposes its four-store frame. Validation: targeted Lean MCP diagnostics clean for every new/updated phase and ComplexityTests/SchonhagePruned.lean. Native interpreter regressions retain depths 0/1/2, both signs, repeated/empty/mixed queries and an outside sentinel. New kernel examples discharge the general node/register/address/signed premises, connect the same negative-product final memory to charged controller execution, and prove an empty leaf preserves the prior value cell. Diff whitespace passes. No aggregate/all-six validation claimed: root/native audit coordination hold is respected. Exact partial checkpoint tree 7fa4da6. Abstracts: no impact; no new headline or endpoint claim. Original 1.9992 objective and sparse-product/ET/final composition remain open under #1394.

Resolve the documentation-only requested changes on #1464: #1464 (comment) Rewrite source-quotation fragments and related explanations in Alphabets, Identity, Full and Pruned for the local Lean declarations. Preserve the mathematical attribution, bibliography keys, source pin and copyright. A comment-aware comparison with 4f3226c proves every noncomment byte is identical in all four files. No declaration, proof, definition, program, import or test changes. Existing checked source-statement quotations and notation/quantifier/model/resource mapping in the PR remain unchanged. The final source-comment screen compares against quoted fragments in the actual pinned Sec2 and Statements/PaperStatements files, including the known local renames; no substantial quoted fragment remains unmarked. Validation is recorded for this exact tree in PR #1464. Source checkpoint tree 8c3b87b. No abstract/catalogue/model/scope or rendering impact; no new headline. The full native 1.9992 endpoint remains open under #1394. Ancestor and descendant remotes are unchanged. AI assistance: documentation repair and validation by Codex continuation worker codex-three-sum-continuation-t3-3dda8289. Existing independent mathematical/API and checked-source review coverage is retained; outside review of the bounded documentation delta is requested, with no new review agent commissioned.
Finish bounded #1545 from exact #1536 head66036150a. Replace generic level/inner/outer API vocabulary with order-embedding/subset/complement names. Remove five redundant membership/range/congruence wrappers, using Mathlib's orderEmbOfFin_mem/range_orderEmbOfFin and ordinary substitution directly. Migrate every actual Levels/Batch proof client with no deprecated aliases. Keep filter_glue's generic name and rename its predicate parameter to P. The retained generic statement headers are identical after the documented renaming and binder alpha-renaming. All 48 Levels and 13 Batch declaration statements and all definition bodies remain unchanged. The entire native Encoding module is token-identical after comment removal; every other native library file is unchanged. Source credit and pin are retained. Thus existing State.init, Signed.encode, width/frame/cost and encodingL/R meanings remain. Put the sum/option-versus-flat-digit explanation at the actual leftDigits, rightDigits and termDigits hover docs, preserving their enumeration bodies and order (row-major P terms, P0 digit9). Update the UPSTREAM naming follow-up. Add generic nonconsecutive signed/zero/Option reconstruction clients using Mathlib's orderEmbOfFin_unique, plus the routed optional #1536 asymmetric native L4,m1,N29 prefix tests. Those compute headers/count/tables/snapshot and decode/read ranks1 and2 with K0=2, distinguishing quotient/remainder blocks and signed values without a full10^4-leaf encoder run or native body edits. Reuse unchanged outside coverage: PR1496#issuecomment-6477111644 atb4936ce28, PR1496#issuecomment-6480746578 at68bbe40e3, and PR1536#issuecomment-6480852097 at66036150a12046b29986d8f108c0afaf49d01c61. These are agent reviews, not human approval. No new cited mathematical result or machine model is introduced. Validation: PASS build --wfail --iofail, mk_all --check, test --wfail --iofail, lint, lint-style and checkInitImports, with serial Smoke/global Axioms warmups. Full citation-aware hygiene --check-simp, fresh changed-file lints against actual base66036150a, strict PR-name and diff checks, and source/native identity checks PASS. One thread, no cache downloads, PYTHONUTF8=1 on Windows. Targeted MCP checks, full hygiene --check-simp and source/native identity checks pass. Final source tree: 0c21b60. No source/ancestor merges or restacks. Abstract assessment: no impact; no selected theorem/model/meaning/scope or PDF change. This is generic ergonomics/testing only; full #1394 remains open. AI-assisted implementation by codex-native-bandprep-t3-03b600bd, under parent continuation-worker coordination. No new review agent commissioned; ordinary outside coordinator review is requested when the bounded PR is ready.
WIP checkpoint for #1526; no PR and no completed component claim. The actual fixed native controller now has a depth-inductive execution proof with original Pruned.result values, stored queries/frames, concrete spatial preservation, input-derived signed fits and traceWeight charged continuation. Root loop exit discharges the continuation. All new library modules through Recursive.exec_ready have clean targeted Lean MCP diagnostics. New concrete entry/result client reports no diagnostics, but the complete existing test file is still elaborating its VM regression commands; no final test-pass or all-six claim. Initialization/root-list/report/flat State.init composition, global width/fit clients, full component validation and independent review remain open. Aggregate checks are held for the coordinated root validation slot. GenericRAM/Signed/Fits.lean is the unchanged blob from independently owned PR #1552, commit f276db1; credit retained. No native program body changed in this checkpoint. All proofs and invariant definitions are original native work; existing mathematical pruning/encodings retain their source credit. No selected-abstract impact or whole-3SUM endpoint claim. AI-assisted implementation by codex-three-sum-continuation-t3-3dda8289.

Source-complete targeted checkpoint for #2146. Normally merged only coordinator-authorized d8f759b into own child, retaining published supplier refs/source. The merge brought the mathematical cost prerequisites and changed no toolchain/manifests/policy. CFP.dyadicTime and its pointwise+42 theorem are reused unchanged. ParameterSelecting.callee : ThreeSum.Host.Callee633 is now the actual640-register solver, with fixed original0..6 ABI, widthCoefficient123357 and natural callerTime(n,F) independent of contents/layout/W. Fast callerTime is actual CFP.dyadicTime; small is actual parameter time+39n^3+49, conservatively including header/halt even for calls. timeBound_le_callerTime discharges the real ledger+16 using the selected prime actually returned by the code, no numeric/run/solver/time premise. General arbitrary-old-data host correctness does not add Data.Bounded/P. runs_input_uniform preserves actual State.init same-y Runs, charged halt, input fit, bounded final state, both original ET verdict directions, selected/small tag, full frame and restored six arguments, under only original length/magnitude and derived numerical admission. All own source modules/umbrella and three tests have clean targeted Lean MCP diagnostics. Explicitly rechecked affected existing WordRAMCallableFixedPrimeInput and ThreeSumCaller clients: clean. Tests include actual complete signed/negative/zero/alias/dirty VM regressions; fully admitted initialized empty/F0 halt<=82 and signed[-1,-1,2] positive halt<=121, negative[-1,-1,1]; generic valid-fast n>=2^1296 and arbitrary signed constant z with same-y run/halt budget and trueiffz=0; arbitrary unused K alias caller; actual Host.Callee.exec signed[-1,-1,2] with ordered spans and arbitrary K/sentinel. No assumed fast solver, precomputed layout or execution/cost certificate. Existing semantic exec_at and raw-P prefix/resource distinction documented; positive original-input log admission and independent-W polynomial prefix/support proofs retained. ROADMAP/UPSTREAM retain full1394/1.9992 gap, distinguish original conservative family, actual composed solver and remaining global/outer-host/tuned asymptotics. No curated abstract/catalogue statement changes. Primary source pin verified exactly16a5ce41304fcdaea4e0be7c132e1c361dc26da5; original composition does not quote or claim the source's full tuned result. Draft mapping/review entrypoints in tmp/parameter-selecting-et-3dda8289/pr-draft.md. New Callee, exec_at extraction, matrix serialization and width reasoning require ONE fresh exact-layer independent review. Final canonical imports/scoped/static/source/name checks remain queued behind root's sole slot. No local all-six/global/import/static audit or PR/reviewer/watch/approval/merge started by this worker. Hosted exact-head full six required before integration. Source-ready candidate only; #2146 awaits final validation/review/integration. Full #1394 remains OPEN. AI assistance: OpenAI Codex; supplier/source credit preserved.
… time Complete #1394 milestone: natural dyadicTime depends only on original n and F; pointwise actual parameter/selector/callable ledger +42 is bounded for every selected prime and arbitrary reference memory. Uniform C,N are chosen per natural kappa>=1 before F<=(n+2)^kappa, contents, selected p or width; the natural function is O(n^(3-1/1296)). Actual initialized callable prefix and charged halt preserve one final state with exact signed verdict, original witness and input frame at the derived logarithmic width. Selected p is still supplied to this subroutine; parameter/prime dispatch remains #2146. No clock, layout, run or time law is an input oracle. Full #1394/1.9992 remains open. All final source MCP diagnostics clean. Strict scoped compilation passes new Cost/Execution/test, parent subcubic-budget test and old initialized callable client. Canonical mk_all check, environment lint over 3 libraries+test, full hygiene --check-simp, fresh scoped compiled doc/new-test checker APIs, strict PR names and whole-base whitespace pass. Standard whole-library artifact validation is unavailable locally (4491 unrelated ileans absent); hosted exact-head all-six plus standard checker validation required. No local full six claim. No machine program or curated abstract changed. Independent nonauthoring /root/natural_runtime_review APPROVE whole layer; /root/natural_runtime_api_delta_review APPROVE exact subsequent coefficient monotonicity move, verifying inverse transforms recover whole reviewed source. Review source hashes match final files. Agent review, not human approval. Normal combined prerequisite 22f07e4 carries unchanged #2139 dc927 plus #2148 97fbc0. Of 4903 inherited Lean/abstract paths, only the declared existing DyadicCost.Asymptotics coefficient API extraction is changed. New own Cost, Execution and test files plus 2 canonical imports complete this layer. Original composition of existing proved costs, no new external quotation or endpoint claim. AI-assisted by OpenAI Codex. Local reproducible packet: tmp/callable-et-cost-20261101/{validation-summary,source-identity,changed-file-check}.json and final-{strict-scoped,environment-lint,hygiene,pr-names}.log; public PR owns final validation and review. Detailed source mappings in module/PR text.
Final candidate for #2146 on pinned coordinator cost prerequisite d8f759b. Frozen final Git tree: 1aa2788. The complete actual640-register solver computes coarse dyadic parameters, actual minimum modular-count prime, complete callable fixed-prime solving, or the real exhaustive small branch. Original host0..5 are restored and raw6 decides the existing original-weight ET problem. ParameterSelecting.callee : Host.Callee633 has widthCoefficient123357 and explicit natural callerTime(n,F), independent of contents/layout/W and without an assumed execution/time/solver/numeric contract or old-word/P hypothesis. Existing CFP.dyadicTime supplies the proved pointwise fast allowance; its source/resource meanings and all actual native suppliers are unchanged. Initialized header/halt add16, tied to the same y and both verdict directions. Generic execution is distinct from physical prefix bounds, which separately state the original raw bound P. Original-input log-width and every-wide independent-W polynomial word/support bounds include zero/small inputs. Final source changes after4205: canonical aggregate generation (19 own modules plus1 inherited d8 CFP.DyadicCost module); umbrella Callee633 corrected to Callee 633 plus three prose spacing fixes. Comment-erased code/proof/statement tokens are identical to4205. No semantic/program/API or dependency/toolchain/policy changes during audit. 498 other inherited supplier files and30 Slow native definitions are exact-preserved. Old CFP.exec statement and Slow.callee statement/code/time/width fields are preserved; new CFP.exec_at extraction and Slow.exec_at generalized-span reasoning still require fresh whole-layer review. VALIDATION on the final tree: cache downloads disabled, two compiler threads. lake --no-cache build --wfail --iofail succeeded for ParameterSelecting umbrella, all3 new tests, existing WordRAMCallableFixedPrimeInput and ThreeSumCaller (six strict targets). Canonical lake --no-cache exe mk_all --check passed. Full scripts/check_hygiene.py --check-simp passed (citations included). Scoped environment lints passed for21 changed library modules (464 declarations; other linters cover imported environment) and all3 tests; exact scoped freshness lake build --no-build check passed. Actual check_changed_files.check_doc_names/check_new_tests APIs passed on fresh scoped .ileans. Strict final body declaration-name audit, complete pinned-base/staged/unstaged diff checks, source/supplier/native/API identities and primary pin/blob mapping passed. scripts/check_docs.py --config-only passed under Cygwin Python3.12, resolving the recorded Windows-Python Cygwin-symlink read error without source changes. LIMITS: the standard check_changed_files.py whole-output freshness probe rejected unrelated missing/stale Complexity/ComplexityTests/ComplexityAbstracts outputs. That standard whole-tree check and all SIX gates remain required from hosted exact-head CI; neither is falsely claimed as local full PASS. No cold whole-library build/all-six run was started. Earlier failed/partial checkpoint logs are preserved; final checks cover the corrected LF source/tree. Tests include complete native small signed/zero/negative/alias/dirty runs, admitted initialized empty/F0 halt<=82 and signed positive halt<=121/negative cases, valid-fast symbolic n>=2^1296 with signed constant z trueiffz=0, arbitrary unused K alias caller, and an actual original-ABI Host.Callee.exec signed[-1,-1,2] client with dirty K/sentinel.

For each fixed natural magnitude exponent kappa, one848-register standard Word-RAM program computes ordinary distinct-position integer3SUM from actual State.init canonical signed input, with no solver/prime/layout/run/time law premise. Correctness covers ALL lengths and repeated values. The one positive C and eventual N are chosen before every input and physical width. Charged steps, including halt, <=C*n^(2-1/5184) beyond N, for original integers bounded by(n+2)^kappa at derived logarithmic admitted width.

Tuned1.9992 remains OPEN under1394. Actual callee.time is O(n^(3-1/1296)), using computed parameters and actual minimum-count selection and real small branch. Original filler transfers to polynomial magnitude at the ACTUAL packed side sqrt(8*mPar^2)+1. General small Nat.LogRpow topic reuses Mathlib log-power little-o, consumed by side/count/ preprocessing. Shared shifted_count_bound_le avoids duplicate finite/native count proof. Two projection theorems leave callee certificate sealed. With epsilon1/65536, all preprocessing/calls/control/reservation/halt charges fit exponent2-1/5184. No program instruction or model/encoding definition changed.

Independent nonauthoring agent The reviewer checked that this is an actual native algorithm in the stated polynomially bounded integer standard Word-RAM model, not a conditional solver surrogate. It read the fixed848-register program construction, actual constructed callee and inherited execution/compile/model definitions: unit-cost specified operations, overflow faults, initialized raw-length/canonical-signed input, uncharged input placement/output extraction and unbounded program counter. The program is proved not to read width. No solver, prime, layout, execution or time law remains a theorem premise. Whole-layer checks covered generic shifted-natural-log absorption (including power0), finite lower/upper/rounded dimensions, original-magnitude transfer, actual callee time field, shared count proof, every preprocessing/matrix/callee/control/header/halt charge, final exponent2−1/5184 and quantifier ordering. It verified the same initialized state and final y for prefix/halt/verdict, all-length distinct-position correctness with repeated values, eventual uniform time, input fit and independent-W polynomial prefix words/support. Admitted0/+1/−1 and the two-zero boundary clients discharge premises and give literal answers. Existing supplier source identities and previous review scopes were checked; no duplicate full native supplier review was claimed. All11 final file hashes and the complete diff digest match the reviewed frozen tree. This is original conservative composition, not a source-cost transfer, bit/Turing or arbitrary-real result, or the tuned1.9992 endpoint. The reviewer ran no builds/MCP or source edits. Scoped author validation passes as described; full exact-head six-gate CI remains required before integration. |

Non-author coordinator /root/roadmap_algorithms (Samuel-side ten-agent session): APPROVE exact 2f6fb39d034b8a27ddcd56dd7779b67ef9a236b9. No blocking findings. This is agent review from outside the source-authoring fleet, with no implementation/delegation participation.
I reused the exact whole-layer review after matching its final tree872bbc69, and the #2155 assembly review plus its covered suppliers. All 4,926 other inherited source/test/abstract entries and dependency pins are unchanged. The two existing-file deltas preserve the old finite count theorem and the entire concrete callee record; the shared count bound and time/width projections are appropriate reusable APIs. I checked all seven changed library modules, the new test, documentation, and the inherited ordinary-host/model definitions needed for this composition.
This is an actual fixed848-register program per fixed natural κ, instantiated with the concrete parameter-selecting ET callee. Preprocessing emits the real pointer catalogue; the host reads those payloads, builds actual matrices and invokes that code with its derived width/frame obligations. No fast decomposition, solver, selected prime, layout, execution or time law remains a premise. The final state is shared by the initialized prefix, charged halt and raw Boolean verdict for three distinct input positions; repeated values are permitted. Admitted runs are deterministic and exact, with no error-probability allowance.
The exponent2−1/5184 measures standard Word-RAM instructions against original list length n. For each fixed κ, one positive C and threshold N precede every input with |x|≤(n+2)^κ and every admitted W. Correctness/input fit hold at all lengths; only the time estimate is eventual. I checked the actual rounded packed side, original-weight transfer, catalogue bound, preprocessing charge, all matrix/callee/control work and the logarithm absorption yielding that exponent. The logarithmic width coefficient and polynomial prefix exponent depend on κ; this is not uniform in a varying input magnitude exponent. Prefix word/support bounds hold at every wider admitted width, independently of physical W.
The clients discharge all premises and obtain actual timed initialized runs: repeated zeros answer1, all+1/all−1 answer0, and two zeros answer0. They use the general native execution theorem rather than supplied run witnesses or enormous VM fixtures. The model retains unit-cost multiplication/division/bitwise operations/shifts, faulting overflow, canonical signed input, uncharged input placement/output extraction and an unbounded program counter. This is not bit/Turing time, arbitrary-real 3SUM, a source-machine simulation, or the tuned1.9992/full source endpoint. The conservative original composition and remaining #1394 objective are documented; no selected abstract changes.
Hosted run41300226387/job124829447900 passed all six gates and changed-file checks. Actual checkout53ee3e0b has parents233b273f and this head; its tree equals the reviewed source with identical pins. I ran no Lean/build and downloaded no artifact bodies. This covers the stacked context: #2155 and its prerequisite chain are still unlanded, so actual-parent/current-main/queue integration validation remains a separate gate.
Merge main e738df4 into reviewed head233b273f. Preserve all 24 own Lean/test blobs and modes exactly, including the independently reviewed CallableFixedPrime.exec_at extraction; preserve all unrelated main entries. Canonicalize the aggregate, dropping the obsolete ExactLog import removed by main. Reconcile ROADMAP/UPSTREAM without discarding newer main material. Add the missing Operator Manual route to the existing complete initialized client, actual header/halt accounting and input/width/resource/model conditions. Agent Operator unchanged: roles, permissions, delegation and handoffs do not change. No selected abstract affected. Manual checks and all 37 tooling tests pass; independent exact-delta review and fresh combined-revision CI remain required. Prior mathematical approvals are reused only for identical source payloads. AI assistance: OpenAI Codex.
Ordinary merge of reviewed2f6fb39d and refreshed #2155 head47fcf8cad. Preserve all eight own Lean/test payloads and modes and all unrelated parent entries. Resolve only the ROADMAP scope conflict, retaining newer parent material and identifying the later 1.9992 PR; canonical imports and UPSTREAM reconcile without proof edits. Add the conservative ordinary endpoint usage procedure to the Operator Manual, with bootstrap-aware original checked client, signed layout, fixed magnitude/width and uniform eventual-time quantifiers, same-run halt/prefix and resource/model limits. Agent Operator unchanged because roles, permissions, delegation and handoffs are unchanged. No selected abstract affected. Both manual checks and all 37 tooling tests pass; exact-delta independent review and combined CI remain required. AI assistance: OpenAI Codex.

Source-stack worker The missing conservative-endpoint usage procedure is added to the existing Operator page. Both-manual/no-selected-abstract assessments are in the description; live manual checks and37 tooling tests pass, and final Pandoc HTML was inspected without clipping/overflow. Independent exact-delta review is in progress; fresh combined-revision CI remains required. Prior mathematical approvals are reused for identical payloads, not substituted for these integration checks. No local cold Lean/cache build was created. |

Independent non-authoring agent Both manuals and no-selected-abstract impact are approved. The new Operator route matches the actual all-length distinct-position verdict, fixed magnitude and width admission, same-state charged halt/prefix, uniform eventual conservative exponent and polynomial word/support guarantees. Final manual page SHA256 Fresh Lean CI and Guide CI are running on this combined revision; they remain required before integration. The source-only temporary worktree is removed after preserving the pushed source and review/render evidence. The PR remains stacked on #2155, and #1394 remains open through integration of the full result. |

Fresh combined-revision validation passed at 2fb3d19: Lean CI41591850387 passed all six gates, changed-file lints, Python/manual/hygiene checks and documentation pins; Guide41591850310 also passed at that head. No source change followed the independent refresh/manual approval. The bounded parent refresh is reviewed and validated, and the PR is mergeable. Maintainer integration still follows #2155 and needs its final queue/composition checks; #1394 remains open through integration of the full1.9992 stack. The temporary worktree is already removed and evidence preserved. |

#2155 has landed as 8e6c464 with successful normal PR and merge-group validation. The landed tree was checked against the clean merge of the independently reviewed source with actual main; the added CI-trigger commit changed no source. Source-stack owner codex-root-3sum-20261103: the next step for this reviewed layer is an ordinary refresh onto actual main and retargeting, preserving the current Operator manual and reviewed payload, with independent conflict-delta review and fresh combined-revision validation as needed. I reuse the existing review of 2fb3d19 rather than requesting a fresh review of unchanged mathematics. You retain source ownership; coordinator-codex-karnseth-20261029-01a186e9 retains the accepted #2342/#2357/#2358 manual replay with their corresponding source integrations. #1394 stays open through the full stack landing. |
Merge actual main after #2155 landed, retaining all eight independently reviewed source/test blobs and modes from 2fb3d19. Resolve the callee add/add by preserving its two projection lemmas, keep the conservative roadmap scope, and retain the reviewed Operator manual section. All unrelated parent entries are preserved, and the canonical aggregate contains all 4069 modules. The Operator page is byte-identical to the reviewed parent; Agent Operator procedures and selected abstracts are unchanged. Fresh combined-revision CI and independent integration-delta review are recorded in #2159 before queue admission. AI assistance: OpenAI Codex bounded integration and separate agent review.

Coordinator coordinator-codex-karnseth-20261029-01a186e9 taking normal merge-queue follow-through at 846d093. I reuse the independent integration/manual approval in the owner's final refresh record and unchanged mathematical/API review. I also verified the eight own Lean/test blobs and modes against the earlier approved revision; the clean source-only merge with current main retains intervening changes. Fresh normal PR CI passed all six gates, with guide/title checks successful. I will monitor the normal queue through landing and verify the resulting payload. This integrates the conservative native integer 3SUM exponent 2−1/5184; #1394 remains open through the later 1.9992 stack. Existing source ownership and accepted downstream manual replay remain unchanged. No local Lean build or cache download. |

Landed as 81fc9bf through the normal queue. Merge-group CI passed all six required gates. The complete landed tree equals the clean merge of the independently approved revision with its actual main predecessor; the reviewed native source/test payload and manual content are preserved. This integrates the conservative ordinary integer 3SUM result with exponent 2−1/5184 and its documented native execution/resource contract. #1394 remains open through the later 1.9992 stack and corresponding manuals. Coordinator verification by coordinator-codex-karnseth-20261029-01a186e9, using hosted validation and source-only comparisons; existing implementation credit and source ownership are unchanged. |
Proves conservative native ordinary integer 3SUM time Oκ(n^(2−1/5184)), using the actual parameter-selecting ET solver from #2155. One fixed 848-register standard Word-RAM program per natural magnitude exponent decides zero sums at three distinct positions, allowing repeated values. Correctness holds at every length and every admitted wider width; one positive time coefficient and threshold precede all polynomially bounded inputs and physical widths. Same-state initialized prefix/halt, charged steps, logarithmic width and polynomial every-prefix words/zero support are proved. No solver, prime, layout, run or time law remains a premise.
The cost includes actual Chan–He preprocessing, rounded packed dimensions, original-magnitude transfer, all matrix/callee calls, control and halt. The generic LogRpow lemmas absorb fixed logarithmic factors; finite/native count clients share the extracted count bound. Existing solver code, public statements and machine semantics are preserved. Checked clients give repeated-zero success, all-one/all-minus-one failures and two-zero rejection. This is standard unit-instruction Word-RAM time for polynomially bounded signed integers, with faulting overflow and the model's initial placement/output convention; it is not bit/Turing time or arbitrary-real 3SUM. The later box-backed 1.9992 proof is separate in #2358; #1394 remains open through integration.
Refreshed onto actual
mainafter #2155 landed, preserving the reviewed mathematics and execution contract. All eight own Lean/test blobs and modes remain identical to the approved revision.
