The artefact-kind reader decodes with plain encoding/json: a duplicate top-level key takes the last value ({"kind":"wasm","kind":"binary"} reads as binary) and lockstep object entries decode case-insensitively ({"PATH":..,"JSON_POINTER":..} accepted) while the top level refuses Kind.

Grounds

• pursued: a declaration with a repeated kind, a repeated entry path or an upper-case entry key is refused before any verb writes; TestParseArtefactRefusesRepeatedAndCaseFoldedKeys accepting any of them would show it wrong
