한국어: Back to Math Lab

NPA / Certificate-first proof checking

한국어: NPA: expose the proof evidence boundary before trusting a result.

한국어: This page reconstructs the NPA section from Math Lab as an independent evidence page: public status, trust model, proof pipeline, claim register, repositories, sources, and explicit non-replacement language.

한국어: Public recheck: 2026-07-02. The NPA repository latest git tag is v0.2.0; npa-std is v0.1.0; npa-mathlib is v0.1.30. Package README pins are shown as repository-specific context and are not flattened into one NPA version claim.

한국어: NPA evidence page preview showing certificate checking and trust-boundary inspection
한국어: The visual is a static preview of the certificate-checking result and trust-boundary explanation. It is not a live NPA trace.

Public status

한국어: State what is public, what is evidence, and when it was rechecked.

한국어: This page makes the page's basis visible: a local truth snapshot, a public repository source, and the final prelaunch readback date.

공개 상태

한국어: Research and implementation repository

한국어: The GitHub repository is public, but this page describes a research and implementation repository, not a deployed service.

Public recheck

2026-07-02

한국어: The public-source readback was completed on 2026-07-02. The original source reconstruction still uses the 2026-06-21 local truth snapshot.

Evidence

Certificates and hashes

한국어: The source snapshot records canonical .npcert, certificate_hash, export_hash, axiom_report_hash, and checker verdicts.

License

Apache-2.0 verified

한국어: Apache-2.0 was verified for npa, npa-std, and npa-mathlib through public LICENSE metadata on 2026-07-02.

Boundary

한국어: NPA is not a practical replacement for Lean or Rocq. The distributed browser inspection simulation does not run NPA itself. Public tags, license, and repository visibility were checked on 2026-07-02 for the final publication readback.

Trust boundary

한국어: Move only a canonical certificate across the evidence boundary.

한국어: The boundary is not about which tool looks sophisticated. It is about which artifact is allowed to become evidence after independent checking.

한국어: Parser, elaborator, tactics, automation, theorem search, plugins, AI systems, source files, replay files, theorem indexes, publish plans, CI status, release pages, and registry metadata stay on the untrusted candidate side.

한국어: Proof pipeline / explanatory simulation

한국어: Show the exact pipeline from certificate bytes to checking evidence.

한국어: The browser simulation does not run NPA itself, Rust, WASM, or real proof certificates. It visualizes the source-free checking order that real artifacts must satisfy.

Verdict

한국어: The explanatory pipeline has not run yet.

한국어: Run the explanation to mark the source-free checking path in order.

Claim register

한국어: Separate evidence, time-sensitive facts, and boundary claims.

한국어: The page does not depend on loose research copy. Each public statement is tied to a local truth snapshot, a source, and a publication action.

한국어: Claim한국어: Public wording상태한국어: Source한국어: Publication action
CL-001 한국어: NPA is certificate-first: the auditable boundary is the canonical .npcert artifact and the checking path around it. 한국어: Verified public claim S01 / 2026-07-02 한국어: Review when the README changes.
CL-002 한국어: The 2026-07-02 public recheck found the NPA repository latest git tag at v0.2.0. Related package READMEs still show repository-specific pins, so version wording stays scoped by repository. 한국어: Verified public recheck S01 / S02 / 2026-07-02 한국어: Keep tag wording scoped by repository.
CL-003 한국어: The local truth snapshot records a Rust 1.95.0 toolchain pin; it is not used as a marketing claim. 한국어: Verified, time-sensitive S01 / 2026-07-02 한국어: Recheck if the toolchain version is displayed.
CL-004 한국어: NPA is not a practical replacement for Lean or Rocq. This boundary must stay visible beside any comparison. 한국어: Verified boundary claim S01 / S03 / S05 / 2026-07-02 한국어: Retain the disclaimer.
CL-005 한국어: npa-std and npa-mathlib are separate public theorem-package repositories in the finitefield-org organization. 한국어: Verified public claim S01 / S02 / 2026-07-02 한국어: Recheck repository visibility again if publication is delayed or repositories change.
CL-006 한국어: The npa, npa-std, and npa-mathlib repositories each expose Apache-2.0 licensing through their public LICENSE metadata. 한국어: Verified public claim S01 / S02 / 2026-07-02 한국어: Recheck LICENSE on a major release.

Repositories and license

한국어: Keep code, package repositories, and organization visibility explicit.

한국어: Repository links are public-source pointers, not guarantees that the current page is synchronized with the latest GitHub state.

Proof ecosystem guard

한국어: Clarify roles before comparing proof tools.

한국어: This is a role table, not a ranking. Lean and Rocq remain the reference proof-assistant ecosystems; NPA is presented as certificate-centered research and implementation work.

한국어: ItemLeanRocqNPA
한국어: Position 한국어: Open-source programming language and proof assistant. 한국어: Interactive theorem prover with a long research history. 한국어: Research and implementation repository for certificate-first checking.

FAQ

한국어: NPA status and verification boundaries.

한국어: The answers emphasize the trust boundary before readers confuse a research page with a deployed proof-assistant service.

한국어: Read about the company
01 한국어: Is this page a product guarantee?
한국어: No. NPA is shown here as a research and implementation repository.
02 한국어: Can NPA replace Lean or Rocq?
한국어: No. NPA is not a practical replacement for Lean or Rocq.
03 한국어: Does the page run real NPA verification?
한국어: No. The browser simulation does not run NPA itself, Rust, WASM, or real proof certificates.
04 한국어: What counts as evidence here?
한국어: The certificate artifact, deterministic hashes, Rust kernel/verifier result, source-free reference checker result, and axiom report form the checking-side evidence.
05 한국어: Which facts need rechecking?
한국어: Current public version, repository visibility, toolchain pins, license text, and source wording were rechecked on 2026-07-02.

한국어: From proof discipline to operations

한국어: Use the same evidence discipline when a business decision must be trusted.

한국어: For business systems, the useful lesson is not to add theorem proving everywhere. It is to decide what must be generated, checked, logged, corrected, and approved by people.
