# Famulus Expertise

> An issue reconstructs one argument or one passage of a source and grounds every step in the edition. Single studies that can be checked: every statement about the source can be tested at its place in the source, by readers and by programs.

Publisher: OpenScienceTechnology GmbH. Editor: Gerd Graßhoff. Licence: CC BY-NC-ND 4.0 (https://creativecommons.org/licenses/by-nc-nd/4.0/): issues may be quoted with their citation and passed on unchanged for non-commercial purposes; no adapted versions.
Cite an issue with its version; cite a place by version and section number (the pages have no page numbers).

## Publication rules

- R1: Every statement about a source carries a sharp Famulus reference: the address of a sentence, a paragraph, a span of text, a figure or a segment.
- R2: Quotations come from the edition. A typed wording stands at the place named.
- R3: No factual statement without justification. What is not grounded is named in the issue as a gap.
- R4: No evaluative, intensifying or meta-linguistic insertions and no filler prose.
- R5: The terms follow LWgrammar and the dictionaries of the collections of the sub-series.
- R6: The bibliography is complete and checked. Nothing is invented.
- R7: A published version is not changed; a correction is a new version under the same number and address.
- R8: Every issue carries a machine-readable preamble (famulus-expertise/1) and publishes the verdict of its quality gates.
- R9: The author alone is responsible for the statements of the issue. Procedure, references and gates are necessary conditions; they do not replace his responsibility.
- R10: No issue is beyond error. An objection to a thesis or an assumption that stands up to examination is annotated at the point concerned in a new version, for readers and for agents.

## Quality seal

An issue carries the quality seal when three necessary conditions hold and the author has released exactly this version.
- Procedure: the issue has completed the pass through Famulus Lektor. The author has explicitly agreed to every thesis, every premise and every step of the proof.
- Grounding evidence: every statement about a source rests on a sharp Famulus reference that resolves; a quoted wording stands at its place.
- Argumentative correctness: the methodological criteria of the series are fulfilled, that is, every blocking quality gate.
- Release: the author releases every version explicitly. Nothing appears without release.

## Open critique

Open critique: objections to an issue are recorded, examined by the same standard and kept with their outcome. An objection that convinces stands at the point concerned in the next version.
Objections go to gerd.grasshoff@opensciencetechnology.com in the format famulus-objection/1 (https://famulus.lettre.ai/expertise/schema/famulus-objection-1.md); persons and agents may file them.
