e2ee-ng SKILL.md skillA

e2ee-ng from sparq-org/sparq is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned
mdr add sparq-org/sparq/e2ee-ng@git:20261014.9efae14

Pins git:20261014.9efae14 in mdr.lock. Pin the fingerprint instead.

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…

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.

What the file says

# sparq-e2ee-ng — E2EE-NG profile primitives (capability / envelope / epoch)

`sparq-e2ee-ng` implements the low-level cryptographic **primitives** of the
NextGraph-style **E2EE-queryable profile** designed in
[`research/e2ee-nextgraph-variant-gpt56-2026-07.md`](../../research/e2ee-nextgraph-variant-gpt56-2026-07.md)
(program `sq-tag1q`). In that profile an RDF dataset is a local-first repository:
encrypted content-addressed blocks carry a causal DAG of encrypted commits; an
always-on broker stores and routes *opaque* blocks but never sees a SPARQL
request. This crate is the **capability / envelope / epoch** layer that everything
else is built on.

<!-- privacy-claims-allow: The whole "Maturity" block is a NEGATIVE/scoped honesty caveat
     (explicitly denies any proven soundness/privacy claim, states designed/intended only,
     and names the sq-qhy4 gate) — not an achieved-property claim. -->
> **Maturity (read first).** RESEARCH-GRADE and **externally UNAUDITED**. Every
> confidentiality, integrity, authorization, revocation, and convergence property
> is **designed/intended, NOT proven** — the construction has had no external

How to install

The exact contents, by fingerprint
mdr add sparq-org/sparq/e2ee-ng@sha256:3c0888de11df27fd

The line at the top of this page pins the label git:20261014.9efae14, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
