reasoning.json
Creates an ARP v1.3 file with an entity's own statements about itself (self-description), plus the readable
reasoning.md and the snippets that make both files findable. Statements are written in the third person,
e.g. “Acme Corp was founded in 2019 (HRB 12345).” Signing is optional: ARP Signer
or arp_cli v1.4.0.
