Formal math & proof

Inspectable pieces of a proof pipeline: premise retrieval over a copied Lean Std index, tactic routing, verifier-trace repair, and claim-separation result records. Three components run the real Lean/Lake prover locally on bounded examples; the rest publish the pipeline's checking layers as contracts you can open.

Looking for the larger Lean formalisation? The cards below are Plectis proof-adjacent components (bounded witnesses, certificates, and pipeline checks). The separate Erdős #249/#257 Lean 4/Mathlib repository is github.com/wcook04/plectis-lean-erdos249-257. That repository carries the mathematical proof authority; this area does not.

Components

Each card below is one component. It states what the component does, the evidence behind that claim, and its scope limit: the line where the claim stops and nothing further is proven.

Certificate Kernel Execution LabRuns the Lean verifier over a small public proof project and reports which rows it accepted.4/5Runs real tools

Job Runs the Lean verifier over a small public proof project and reports which rows it accepted.

Scope limit It is a local tool-witness that the declared public fixture rows compiled and were adjudicated by the local Lean verifier; it excludes general proof authority, count oracle/provider output as proof, expose proof text, change source files, claim a benchmark solve-rate, or include launch operations.

Formal Math Lean Proof WitnessCompiles a tiny Lean example with the real prover and records whether it built, leaking no proof text.4/5Runs real tools

Job Compiles a tiny Lean example with the real prover and records whether it built, leaking no proof text.

Scope limit It authorizes only a witness that a tiny declared public toy proof compiled under the locally installed Lean/Lake toolchain in a temporary workspace, plus confirmation that its leakage guardrails fired. It excludes Mathlib/Aesop/Batteries-dependent or general proof or theorem-program authority, external model access, private proof import, benchmark or performance claims, whole-system correctness, or any launch, hosted deployment, or public sharing.

Verifier Lab Execution SpineRuns Lean on small bounded proof attempts in a temp copy and records what passed or failed.4/5Runs real tools

Job Runs Lean on small bounded proof attempts in a temp copy and records what passed or failed.

Scope limit It is a tool-witness result record for bounded public Lean transition rows only: it does not establish general proof authority, count oracle/provider output as proof, export proof bodies or tactic scripts, use external model services, change source files, claim benchmark solve-rates, or include launch operations/public sharing.

Corpus Readiness Mathlib Absence GateRuns the real Lean toolchain to confirm the math library is absent, then gates proof tasks.4/5Runs real tools

Job Runs the real Lean toolchain to confirm the math library is absent, then gates proof tasks.

Scope limit It only projects and gate-checks recorded corpus/toolchain readiness accounting, re-verifies recorded source digests and leakage guards, and runs a bounded Lean/Lake import probe when a toolchain is present. It does not run a full Lake build, prove formal-result correctness, claim Mathlib is available beyond the probe result, benchmark corpora, score model performance, use external model services, or include launch operations or public sharing.

Proof / Control / Runtime Import BundleChecks fourteen proof, control, and runtime parts as one unit that rejects every overclaim.5/5
Proof Diagnostic Evidence SpineSorts proof-pipeline checks into accepted or rejected without inflating a pass.3/5

Job Sorts proof-pipeline checks into accepted or rejected without inflating a pass.

Scope limit It records proof/evidence diagnostics over existing result record references only. It does not run Lean, use external model services, expose proof bodies, turn a passing check into formal-proof or theorem authority, prove runtime or whole-system correctness, authorize later components, certify public launch, authorize public sharing or recipient work, or establish secret export.

Formal Math Readiness GateReads declared math setups and lists which proof tactics may be attempted versus blocked.3/5

Job Reads declared math setups and lists which proof tactics may be attempted versus blocked.

Scope limit It only validates and projects declared readiness metadata; it does not run Lean/Lake, inspect the real toolchain, use external model services, prove any theorem correct, produce benchmark claims, or authorize Mathlib-dependent proof attempts.

Mathematical Strategy Atlas Hypothesis ScorerPicks a first-guess proof strategy from a problem's tags and flags any it cannot map.3/5

Job Picks a first-guess proof strategy from a problem's tags and flags any it cannot map.

Scope limit It only projects pre-oracle strategy-hypothesis and retrieval mechanics; it does not run Lean/Lake, prove theorems, establish domain or formal-result correctness, reveal oracle labels, expose proof bodies, use external model services, tune on test answers, or include launch operations.

Tactic Portfolio Availability ProbeMaps which Lean proof tactics a recorded run marked usable before any code relies on one.3/5

Job Maps which Lean proof tactics a recorded run marked usable before any code relies on one.

Scope limit It only projects and validates which tactics were recorded as compiling in one captured environment; it does not run Lean/Lake at all, prove any goal, certify domain-level conclusions, use external model services, claim benchmark performance, or include launch operations.

Target Shape Tactic Routing GateRecords an allow-or-reject decision and reason for each proof tactic before any proof runs.3/5

Job Records an allow-or-reject decision and reason for each proof tactic before any proof runs.

Scope limit It only inspects and records the projection mechanics of pre-execution tactic-routing referencesemitting per-tactic allow/reject decisions with reasons. It does not run Lean/Lake, does not establish or judge the correctness of any goal, emits no proof bodies, makes no external model access, performs no post-execution route selection, reports no benchmark claims or maturity, and excludes launch.

Lean Std Premise IndexLists a fixed catalog of public Lean building blocks and confirms none hides proof text or test answers.3/5

Job Lists a fixed catalog of public Lean building blocks and confirms none hides proof text or test answers.

Scope limit It only validates the projection of premise metadata and copied source bodies; it does not run Lean or Lake, prove any theorem correct, expose proof bodies or oracle-needed ids, use external model services, produce benchmark claims, or include launch operations.

Formal Math Premise RetrievalShows which lemmas a plain search surfaces per query, and never leaks proof text or answer keys.3/5

Job Shows which lemmas a plain search surfaces per query, and never leaks proof text or answer keys.

Scope limit It only checks that public retrieval metadata is internally coherent, term-scored over a copied index, budget-bounded, and leakage-clean; it does not run Lean/Lake, use external model services, prove any theorem or its own correctness, claim benchmark performance, or include launch operations.

Formal Math Verifier Trace Repair LoopReplays how a proof lab turns verifier failures into fixes, with no promotion without a fresh re-run.3/5

Job Replays how a proof lab turns verifier failures into fixes, with no promotion without a fresh re-run.

Scope limit It demonstrates control-loop projection mechanics over copied Ring2 run rows only; it does not run Lean/Lake, use external model services, expose proof bodies or oracle premise ids, treat human or provider advice as correctness, prove any theorem, or include launch operations.

Formal Evidence Cell Anchor ResolverResolves each proof-flavored math claim to named evidence and flags ones that overreach or lack backing.3/5

Job Resolves each proof-flavored math claim to named evidence and flags ones that overreach or lack backing.

Scope limit It validates claim-to-evidence anchoring mechanics only: claim-to-cell resolution, source-anchor presence, permitted claim strength, copied-source-module digest checks, and leakage refusals. It does not run Lean/Lake, certify theorem or mathematical correctness, expose proof bodies or non-public source refs, use external model services, or include launch operations/public sharing.

Undeclared Library Prior Symbol ClassifierDetects when a checked Lean proof cites a library result outside its approved set.3/5

Job Detects when a checked Lean proof cites a library result outside its approved set.

Scope limit It only projects the symbol-boundary classification mechanic over copied Lean/Std premise rows and pre-extracted symbol observations; it does not read proof source, run Lean or Lake, prove formal-result correctness, treat the whole standard library as an implicit allowlist, claim Mathlib availability, use external model services, or include launch operations.

Ring2 Premise Retrieval Precision Recall HarnessScores how much proof support a premise search found, problem by problem.3/5

Job Scores how much proof support a premise search found, problem by problem.

Scope limit These are after-the-fact retrieval-attribution labels and precision/recall counts over copied run records only. The component does not run Lean or Lake, call any provider, expose proof bodies, tune on test answers, claim benchmark performance, prove formal-result correctness, or include launch operations, and its labels are explicitly forbidden from flowing into provider context. The aggregate numbers describe only the copied fixture/bundle replayed, not any benchmark claims.

Verifier Lab KernelFolds nine proof checks into one report labeling each line by which source actually backs it.5/5

Job Folds nine proof checks into one report labeling each line by which source actually backs it.

Scope limit It validates the declared public contract shape of the proof packet and component result records only; it does not establish anything correct, count oracle/provider output as forward proof success, import private or Mathlib-dependent proof bodies, use external model services, change source files, or claim benchmark solve rates, launch, or maturity.

Proof Derived Governed Mutation AuthorizationChecks a synthetic change-authorization record for its proof-and-approval chain, bound to a real commit.5/5
Finite Erdos Denominator-Order Certificate StrikeComputes an exact-arithmetic denominator-order identity and catches forged ones, not the open Erdos problem.4/5Runs real tools

Job Computes an exact-arithmetic denominator-order identity and catches forged ones, not the open Erdos problem.

Scope limit It computes the finite denominator-order certificate ord_Q(b)=lcm(F) for S_F(b)=sum 1/(b^n-1)=P/Q in exact rational arithmetic over bounded public fixtures and rejects forged certificates by recomputation; it does not establish the open infinite Erdos #257 problem, is not an oracle, prover, or provider result, and a holding certificate is a bounded computational witness, not a machine-checked proof.

Lean Proof-Search Lab RuntimeFinds tactic scripts the real Lean prover accepts on toy theorems, and refuses proofs that cheat.4/5Runs real tools

Job Finds tactic scripts the real Lean prover accepts on toy theorems, and refuses proofs that cheat.

Scope limit This standard governs a bounded symbolic Lean proof-search lab over tiny public toy-theorem fixtures whose verdict source is the installed Lean subprocess only. It is not neural theorem proving, does not solve any open mathematical problem, does not forward oracle proof bodies, is not frontier-scale math automation or online-RL bandit search, is not a private source prover-run export, and excludes launch or public sharing.
