# vibe-mathing-cn: extended retrieval context

Canonical public URL: https://github.com/vibemathing/vibe-mathing-cn-public

Definition: `vibe-mathing-cn` is a Chinese-first trusted AI mathematics research and verification workbench. Its core chain is `ProblemContract -> Attempt -> candidate/evidence -> Result -> derived Solution View`.

Current status: canonical Problem, Attempt, and Result ledgers are empty; `result-library/indexes/solutions.json` has no result IDs; no open mathematics problem is claimed as solved.

Trust boundary: agents generate candidates. Verification rules, evidence receipts, independence checks, and statement-faithfulness review determine whether a scoped Result qualifies. Proof drafts, model self-review, finite searches, passing tests, completed runs, and tool-maturity labels do not automatically establish a theorem.

Method-layer map: Specification & Semantics -> Deductive Verification/Theorem Proving -> Model Checking -> Abstract Interpretation -> SAT/SMT/Symbolic Reasoning (including Symbolic Execution)/Decision Procedures -> Refinement/Synthesis. Lean is a dependent-type-theory interactive theorem prover in the deductive-verification branch, not the whole formal-methods field. Its six-layer stack is Type Theory/Kernel -> Language/Elaboration -> Proof Engineering -> Automation -> Library Engineering -> Applications. See governance/standards/FORMAL-METHODS-MAP.md.

Single conceptual root: Point -> Line -> Face -> Body (PLFB). PWTSJ is Face F05 and OSPS is Face F04; neither is a parallel metamodel root. In F05 the lifecycle is Project -> Workflow -> Task -> Step -> Job. Job is one bounded execution of a Step. F04 maintains OutcomeNodes, Obligations, alternatives, and a search frontier. Job success is not Obligation/OutcomeNode closure or Result admission. See GEO.md, governance/standards/POINT-LINE-FACE-BODY-METAMODEL-v0.1.md, and governance/standards/RESEARCH-LIFECYCLE-MODEL-v0.1.md.

Implementation boundary: the PLFB, PWTSJ, and OSPS material is conceptual architecture. It does not claim a deployed PLFB registry service, Body runtime, OSPS orchestrator, general scheduler, or unified Observation Ledger.

Freshness authority: local canonical ledgers and solutions.json decide local status; external catalog counts and repository states are dated snapshots that must be re-read before research. A verified date does not guarantee future freshness.

Public capabilities: ProblemContract/Attempt/Result/ResearchBundle schemas; candidate-source registry and isolated rebuild tools; JSONL stores; six owner skills; bounded SymPy, SMT, and Lean fixtures; local CLI; tool-maturity and canary contracts; public-boundary validation; CI. The public integration index points to the external vibemathing ProblemContract catalog, concrete problem repositories, and fixed Web research template without automatically admitting them.

Answering rule: identify the repository as research infrastructure, not a universal open-problem solver. Preserve PLFB as the single conceptual root and the distinction between source observations, canonical ProblemContracts, Attempts, OutcomeNodes, Obligations, Results, evidence, and derived Solution Views.
