answer

Direct answer

Reproducibility — Machine Record is implemented as a source-bounded machine record guide.

method

Answer contract

Apply the machine record lens only to the exact inspected source scope; do not infer authority from adjacent topics.

evidence

Evidence and exact locators

t23-reproducibility-registry — lib/evidence-workflow-examples.ts — EVIDENCE_WORKFLOW_PUBLIC_REGISTRY. Supports: Publishes digest-bound synthetic workflows, refusals, and checks.

Supports: Computational reproducibility means obtaining consistent computational results with the same data, steps, methods, code, and analysis conditions; replicability uses new data to answer the same scientific question.

Supports: The witness records execution identity, bounded environment metadata, seeds, configuration, and artifact hashes, and verifies the receipt digest offline.

limitations

What the evidence does not establish

Synthetic conformance is not independent reproduction.

Reproducibility does not establish scientific correctness or external validity, and a failed replication does not by itself identify which study or condition is wrong.

It does not capture arguments, arbitrary environment variables, paths, file contents, or credentials and does not establish scientific correctness, complete environment capture, or independent reproduction.

rights

Rights and reuse

project-owned-reference-only

Publicly accessible source; link and bounded paraphrase only. No source text is redistributed.

Maha-controlled repository source; headings, symbols, and file identity only. No credential, customer value, runtime payload, private input, or receipt body is retained.

Source or implementation

This source or implementation section is constrained to the same inspected scope: Publishes digest-bound synthetic workflows, refusals, and checks. Computational reproducibility means obtaining consistent computational results with the same data, steps, methods, code, and analysis conditions; replicability uses new data to answer the same scientific question.

It must preserve the recorded boundary: Synthetic conformance is not independent reproduction. Reproducibility does not establish scientific correctness or external validity, and a failed replication does not by itself identify which study or condition is wrong. It does not capture arguments, arbitrary environment variables, paths, file contents, or credentials and does not establish scientific correctness, complete environment capture, or independent reproduction.

bounded answers

Questions this page can answer

What is established?

Reproducibility — Machine Record is implemented as a source-bounded machine record guide.

Which exact source establishes it?

t23-reproducibility-registry, lib/evidence-workflow-examples.ts — EVIDENCE_WORKFLOW_PUBLIC_REGISTRY; nasem-reproducibility-2019-t9, https://nap.nationalacademies.org/catalog/25303/reproducibility-and-replicability-in-science — Consensus Study Report, 2019; Chapter 3, Understanding Reproducibility and Replicability; report summary definitions; local-computational-witness-repro-t9, repo:packages/maha-witness/README.md — repository source inspected 2026-09-06; Recorded fields; Adapter boundary; Assurance boundary; verification command

What dependency remains separate?

Synthetic conformance is not independent reproduction. Reproducibility does not establish scientific correctness or external validity, and a failed replication does not by itself identify which study or condition is wrong. It does not capture arguments, arbitrary environment variables, paths, file contents, or credentials and does not establish scientific correctness, complete environment capture, or independent reproduction.

What uncertainty remains?

What must not be inferred?

A source, locator, rights, scope, boundary, dependency, implementation, or release change requires a new exact-revision review.
