NPA / Certificate-first proof checking

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

Ελληνικά: 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.

Δημόσια κατάσταση: Ερευνητικό repository; Ελληνικά: Shown as research and implementation, not as a production assurance service.
Δημόσιος επανέλεγχος: 2026-07-02 / NPA v0.2.0; Ελληνικά: Latest git tags checked: npa v0.2.0, npa-std v0.1.0, npa-mathlib v0.1.30.
Άδεια: Apache-2.0; Ελληνικά: Apache-2.0 was verified for npa, npa-std, and npa-mathlib on 2026-07-02.

Ελληνικά: 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.

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

Public status

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

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

Δημόσια κατάσταση

Ερευνητικό repository

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

Public recheck

2026-07-02

Ελληνικά: 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

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

License

Apache-2.0 verified

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

Boundary

Ελληνικά: 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

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

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

Ελληνικά: 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.

Ελληνικά: Proof pipeline / explanatory simulation

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

Ελληνικά: 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

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

Ελληνικά: 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.

FAQ

Ελληνικά: NPA status and verification boundaries.

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

Ελληνικά: Read about the company

01 Ελληνικά: Is this page a product guarantee?

Ελληνικά: No. NPA is shown here as a research and implementation repository. Client projects still need separate requirements, risk, responsibility, and acceptance criteria.

02 Ελληνικά: Can NPA replace Lean or Rocq?

Ελληνικά: No. NPA is not a practical replacement for Lean or Rocq. The page keeps that boundary visible because it matters for expectations.

03 Ελληνικά: Does the page run real NPA verification?

Ελληνικά: No. The browser simulation does not run NPA itself, Rust, WASM, or real proof certificates. It explains the inspection order.

04 Ελληνικά: What counts as evidence here?

Ελληνικά: The certificate artifact, deterministic hashes, Rust kernel/verifier result, source-free reference checker result, and axiom report form the checking-side evidence.

05 Ελληνικά: Which facts need rechecking?

Ελληνικά: 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.

Ελληνικά: From proof discipline to operations

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

Ελληνικά: 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.
