NPA / Certificate-first proof checking
Polski: NPA: expose the proof evidence boundary before trusting a result.
Polski: 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.
- Status publiczny
- Repository badawcze
- Polski: Shown as research and implementation, not as a production assurance service.
- Publiczna ponowna kontrola
- 2026-07-02 / NPA v0.2.0
- Polski: Latest git tags checked: npa v0.2.0, npa-std v0.1.0, npa-mathlib v0.1.30.
- Licencja
- Apache-2.0
- Polski: Apache-2.0 was verified for npa, npa-std, and npa-mathlib on 2026-07-02.
Polski: 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.
Public status
Polski: State what is public, what is evidence, and when it was rechecked.
Polski: This page makes the page's basis visible: a local truth snapshot, a public repository source, and the final prelaunch readback date.
Public recheck
2026-07-02
Polski: 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
Polski: The source snapshot records canonical .npcert, certificate_hash, export_hash, axiom_report_hash, and checker verdicts.
License
Apache-2.0 verified
Polski: Apache-2.0 was verified for npa, npa-std, and npa-mathlib through public LICENSE metadata on 2026-07-02.
Boundary
Polski: 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
Polski: Move only a canonical certificate across the evidence boundary.
Polski: The boundary is not about which tool looks sophisticated. It is about which artifact is allowed to become evidence after independent checking.
Polski: 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.
Polski: Proof pipeline / explanatory simulation
Polski: Show the exact pipeline from certificate bytes to checking evidence.
Polski: 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.

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

Proof ecosystem guard
Polski: Clarify roles before comparing proof tools.
Polski: 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.
| Polski: Item | Lean | Rocq | NPA |
|---|---|---|---|
| Polski: Position | Polski: Open-source programming language and proof assistant. | Polski: Interactive theorem prover with a long research history. | Polski: Research and implementation repository for certificate-first checking. |
| Polski: Typical use | Polski: Mathematics, software verification, and programming. | Polski: Mathematics, specifications, program verification, and extraction. | Polski: Research into proof certificates, independent checking, and a small trusted base. |
| Polski: Evidence boundary | Polski: Its own trusted kernel and ecosystem define the checking boundary. | Polski: Its own kernel and checked developments define the checking boundary. | Polski: The canonical .npcert artifact crosses from generation into checking. |
| Polski: How this page treats it | Polski: Reference for learning, comparison, and interoperability. | Polski: Reference for learning, comparison, and formalization methods. | Polski: Finite Field research project, not a product promise. |
| Polski: Boundary | Polski: Specialist knowledge is still required. | Polski: Specialist knowledge is still required. | Polski: NPA is not a practical replacement for Lean or Rocq at this time. |

Polski: NPA status and verification boundaries.
Polski: The answers emphasize the trust boundary before readers confuse a research page with a deployed proof-assistant service.
Polski: Read about the company01 Polski: Is this page a product guarantee?
Polski: No. NPA is shown here as a research and implementation repository.
02 Polski: Can NPA replace Lean or Rocq?
Polski: No. NPA is not a practical replacement for Lean or Rocq.
03 Polski: Does the page run real NPA verification?
Polski: No. The browser simulation does not run NPA itself, Rust, WASM, or real proof certificates.
04 Polski: What counts as evidence here?
Polski: The certificate artifact, deterministic hashes, Rust kernel/verifier result, source-free reference checker result, and axiom report form the checking-side evidence.
05 Polski: Which facts need rechecking?
Polski: Current public version, repository visibility, toolchain pins, license text, and source wording were rechecked on 2026-07-02.
Polski: From proof discipline to operations
Polski: Use the same evidence discipline when a business decision must be trusted.
Polski: 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.
