Done: Config files and profiles (appsettings, Spring profiles, Rails YAML)
Done: File inputs: config files, TLS, CA bundles, keystores, text and binary files
Done: Injected values and files (Bank-Vaults, op run, Vault Agent), with the pod annotations and labels that enable each injector
Done: Length limits counted in characters: maxLength on url and json values, itemMinLength and itemMaxLength on string lists
Done: Generated docs: description and details on every input, and a versioned docs model
Done: Config-file overlays, such as a mounted appsettings.Production.json
Done: Language-neutral conformance suite for variables
To do: Conformance cases for file inputs, profiles and overlays
To do: Settle the open questions in the specification

Done: docuconf CLI: export, vet, render, helm
Done: docuconf docs: CONFIG.md for developers and CONFIG.agents.md for coding and ops agents
Done: docuconf check and docuconf exec: boot checks for programs in a language without an SDK
Done: Helm library chart and generated values.schema.json
To do: docuconf diff, push and pull
To do: Crossplane composition function, with readable conditions
