AGPL-3.0

The contract behind every *-dtd command, skill and agent. Load when writing, reading, installing or debugging a DTD-amplified artifact, when a DOCTYPE fails the rdc check, when PCDATA, CDATA, NDATA or NOTATION need to be applied to a prompt, or when a shared subset must be extended.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
