Format Maturity

Where every neokapi format sits against the format maturity model (L0 experimental → L4 rock-solid). Target: L4 Axis grades by family — Comprehension (Engine L0–L4, Vocabulary V0–V3, Structure & Geometry G0–G4); Assurance (Corpus C0–C3, Security S0–S4); Enablement (Knowledge K0–K3, Editor E0–E4).

36 formats · generated 2026-07-25 · source: format-ops bootstrap-publish (deterministic per-axis floor; no quality demotions) · scorer v4

This dashboard publishes two separate things per format. The promise is a support tier — Supported, Maintained, or Available — a CI-backed contract you can rely on, changed only by an explicit, human-approved event. The score is the per-axis vector below, recomputed from file evidence on every audit; it ranks the remaining work and explains the tier, but on its own promises nothing.

The headline tier is the minimum over the gating axes (Engine, Corpus, Knowledge) — never an average. The seven axes group into three families by the question each answers: Comprehension (how deeply we read it), Assurance (how we prove it), and Enablement (how we work with it).

Structure & GeometryG0–G4non-gatingHow much of the document's logical and spatial structure the reader recovers — roles, reading order, tables, relations, geometry (non-gating display axis)

Assurance — how we prove it

CorpusC0–C3Reference files that validate support, with provenance

SecurityS0–S4non-gatingResource-boundedness, fuzzing, and hostile-corpus hardening of the parser (non-gating display axis)

Enablement — how we work with it
