# The protocol seed in one page

MCRP means Minimum Credible Reproducibility Protocol. Its starting question is:
which exact combination of claim, evidence, execution and decision was reviewed?
The publication/trust extension asks which present use that record supports and
what work is needed when a material dependency changes.

The initial human boundary has four actions:

| Action | Small record | Important limit |
|---|---|---|
| Offer | One versioned claim, evidence and requested check | Declared scope can omit something important |
| Check | Performed action, result, evidence and limitations | Agreement is not independent evidence |
| Rely | Responsible decision for a bounded use and version | A role label does not create real authority |
| Amend | Material change and affected uses | A declared graph cannot discover missing dependencies |

These actions are not four exclusive stages. Checks and disagreements can proceed
in parallel. A contribution can remain useful without establishing every premise
for a particular use. Different institutions may reach different scoped decisions.

The simplest allocation baseline is qualified, conflict-aware selection among
declared accountable groups, followed by actual shared-capacity reservation.
Additional trust-routing mechanisms must justify their complexity. A declaration
of common control is an input to the prototype, not a discovered fact.

Three boundaries remain essential. Provenance binds a statement to bytes and an
identity under a stated policy. Check results describe particular work. Scientific
or institutional dispositions require a separately accountable, authorized actor.
The executable examples supply identities and roles as synthetic fixtures; they
do not implement those real-world authorities.

## Relationship to established work

Versioned records, provenance, research objects and data/software citation are
established ideas. MCRP proposes a small lifecycle joining them to explicit
reliance and correction. It does not claim to invent those ingredients or to
conform to a standard merely by using similar vocabulary. The mathematical
manuscript and domain chapters cite the primary sources for their specific claims.

[W3C PROV](https://www.w3.org/TR/prov-overview/) supplies a provenance family;
[RO-Crate](https://www.researchobject.org/ro-crate/specification/) packages research
objects with structured metadata. An adapter should preserve the distinction
between describing provenance and authorizing a scientific use. No externally
validated interoperability implementation is claimed in this release candidate.

## Evidence lineage

This packet follows a private hardening dossier merged into its working source
repository on 25 September 2026. That dossier examined economics, game theory,
scientific dynamics and legal operations with specialist and adversarial agent
lanes. This public export is designed to stand alone: access to private source
history is not required to run the new examples.

The next test is whether people can use a smaller, more legible record to expose
important limits and repair affected uses at acceptable cost. The present toy
models diagnose specified mechanisms; they do not answer that human question.
