e2ee-ng skillA

e2ee-ng is agent-read markdown (skill) from sparq-org/sparq: Build the low-level primitives of the NextGraph-style E2EE-queryable profile for sparq with the opt-in sparq-e2ee-ng crate — deterministic capability encoding with strict read/publish/admin separation, recipient-wrapped secrets (X25519 sealed-box), randomized padded block/commit envelopes (XChaCha20-Poly1305) under a domain-separated HKDF-SHA-256 key schedule, an object chunker that splits a large object into Merkle-linked multi-block sets, Ed25519 author/publisher/admin signatures, signed epoch.

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

How to install

Latest version
mdr add sparq-org/sparq/e2ee-ng@git:20260731.575dd18
Exact content
mdr add sparq-org/sparq/e2ee-ng@sha256:324a4599f6ecd572

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
