Short definitions for recurring patina terms. Each entry links to the deeper reference where the term is used in context.
A 0-100 editing signal for how strongly a text matches patina's AI-writing patterns. Lower means less AI-sounding; it is not proof of authorship. See the scoring overview and the FAQ.
The mode that detects and reports AI-writing patterns without rewriting the text. Use it when you want to inspect what patina would flag before changing anything. See the mode table and examples guide.
The variation in sentence length inside a paragraph, measured with coefficient of variation. Very uniform sentence lengths are one signal that a paragraph may need closer inspection. See Stylometry.
The mode that shows changes pattern by pattern, making the edit auditable instead of a black-box paraphrase. See the mode table and examples checklist.
The document-policy axis. It selects purpose, audience, structural conventions,
domain vocabulary/precision, avoidance rules, and language-scoped pattern
bounds without changing Persona voice, Register, or meaning thresholds. CLI:
--document-type; config: document-type. The historical ids formal and
casual-conversation refer to structured-document and chat/message conventions;
they do not select professional or casual Register.
A meaning-accuracy score comparing original text with a rewrite. Higher is better: it checks whether claims, facts, audience/register, and length stayed faithful. See Fidelity Scoring.
The safety goal that rewritten text should keep the original claims, polarity, causal links, numbers, and other high-risk details. See the FAQ and MPS overview.
Moving Average Type-Token Ratio, a lexical-diversity metric that reduces the length bias of simple TTR. Patina uses it as one stylometry signal, with known language limitations. See Stylometry.
A CLI output path such as rewrite, audit, score, or diff. Modes control whether
patina edits text or reports findings. --verify is a rewrite modifier, not a
separate mode. See the mode table.
Meaning Preservation Score. MPS checks whether extracted semantic anchors survive the rewrite pipeline and whether polarity is preserved. See the FAQ and MPS scoring.
A named AI-writing signal with a fire condition, exclusion condition, problem description, and before/after example. Patterns are the unit patina audits and rewrites against. See PATTERNS.md.
A language and category file such as patterns/en-style.md or
patterns/ko-content.md. Packs group related patterns and provide counts used
by scoring. See PATTERNS.md.
An optional, reusable voice fingerprint. Persona v2 may shape vocabulary,
rhythm, metaphors, and explanation habits; it cannot select Document Type,
Register, pattern policy, or meaning thresholds. Omitting --persona preserves
the source voice.
The casual or professional delivery axis: wording and sentence-ending
markers only. Omitting --register preserves the source register. Genre values
such as academic and marketing are Document Types, while idiolect and rhythm
belong to Persona.
The default mode that removes matched AI-writing patterns while checking that meaning survived the edit. See the Quick Start and MPS integration points.
The mode that returns a 0-100 AI-likeness score. Default scoring combines
LLM-judged categories with deterministic signals; --offline reports the
deterministic subset without a backend. See
Score Interpretation.
A meaning unit extracted before rewriting, such as a claim, negation, number, causal link, quantifier, or polarity marker. Anchors are later verified by MPS. See MPS Anchor Verification Criteria.
A paragraph or sentence group marked for closer inspection by stylometry, usually because burstiness, MATTR, or lexicon signals fired. See the stylometry delivery format.
A score-only pattern class for SNS and marketing signals such as shock numbers, clickbait closes, source-skipping authority claims, short-sentence stacking, and hyperbolic engagement language. See Score-only viral hooks.
