NPA / Certificate-first proof checking
Français: NPA: expose the proof evidence boundary before trusting a result.
Français: 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.
- Statut public
- Repository de recherche
- Français: Shown as research and implementation, not as a production assurance service.
- Revérification publique
- 2026-07-02 / NPA v0.2.0
- Français: Latest git tags checked: npa v0.2.0, npa-std v0.1.0, npa-mathlib v0.1.30.
- Licence
- Apache-2.0
- Français: Apache-2.0 was verified for npa, npa-std, and npa-mathlib on 2026-07-02.
Français: 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
Français: State what is public, what is evidence, and when it was rechecked.
Français: 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
Français: 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
Français: The source snapshot records canonical .npcert, certificate_hash, export_hash, axiom_report_hash, and checker verdicts.
License
Apache-2.0 verified
Français: Apache-2.0 was verified for npa, npa-std, and npa-mathlib through public LICENSE metadata on 2026-07-02.
Boundary
Français: 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
Français: Move only a canonical certificate across the evidence boundary.
Français: The boundary is not about which tool looks sophisticated. It is about which artifact is allowed to become evidence after independent checking.
Français: 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.
Français: Proof pipeline / explanatory simulation
Français: Show the exact pipeline from certificate bytes to checking evidence.
Français: 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
Français: Separate evidence, time-sensitive facts, and boundary claims.
Français: This page does not rely on loose research copy. Each public statement is tied to a local truth snapshot, a source, and a publication action.
| Affirmation | Formulation publique | Statut | Source | Action de publication |
|---|---|---|---|---|
| CL-001 | Français: NPA is certificate-first: the auditable boundary is the canonical .npcert artifact and the checking path around it. | Français: Verified public claim | S01 / 2026-07-02 | Français: Review when the README changes. |
| CL-002 | Français: 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. | Français: Verified public recheck | S01 / S02 / 2026-07-02 | Français: Keep tag wording scoped by repository. |
| CL-003 | Français: The local truth snapshot records a Rust 1.95.0 toolchain pin; it is not used as a marketing claim. | Français: Verified, time-sensitive | S01 / 2026-07-02 | Français: Recheck if the toolchain version is displayed. |
| CL-004 | Français: NPA is not a practical replacement for Lean or Rocq. This boundary must stay visible beside any comparison. | Français: Verified boundary claim | S01 / S03 / S05 / 2026-07-02 | Français: Retain the disclaimer. |
| CL-005 | Français: npa-std and npa-mathlib are separate public theorem-package repositories in the finitefield-org organization. | Français: Verified public claim | S01 / S02 / 2026-07-02 | Français: Recheck repository visibility again if publication is delayed or repositories change. |
| CL-006 | Français: The npa, npa-std, and npa-mathlib repositories each expose Apache-2.0 licensing through their public LICENSE metadata. | Français: Verified public claim | S01 / S02 / 2026-07-02 | Français: Recheck LICENSE on a major release. |
Repositories and license

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

Français: NPA status and verification boundaries.
Français: The answers emphasize the trust boundary before readers confuse a research page with a deployed proof-assistant service.
Français: Read about the company01 Français: Is this page a product guarantee?
Français: No. NPA is shown here as a research and implementation repository. Client projects still need separate requirements, risk, responsibility, and acceptance criteria.
02 Français: Can NPA replace Lean or Rocq?
Français: No. NPA is not a practical replacement for Lean or Rocq. The page keeps that boundary visible because it matters for expectations.
03 Français: Does the page run real NPA verification?
Français: No. The browser simulation does not run NPA itself, Rust, WASM, or real proof certificates. It explains the inspection order.
04 Français: What counts as evidence here?
Français: The certificate artifact, deterministic hashes, Rust kernel/verifier result, source-free reference checker result, and axiom report form the checking-side evidence.
05 Français: Which facts need rechecking?
Français: Current public version, repository visibility, toolchain pins, license text, and source wording were rechecked on 2026-07-02 and should be rechecked again if publication is delayed or repositories change.
Français: From proof discipline to operations
Français: Use the same evidence discipline when a business decision must be trusted.
Français: 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.
