AgDR-Mantle: Sovereign post-quantum fortification for AgDR-Phoenix output (ML-DSA-65, Sparse Merkle, Brotli)

AgDR-Mantle v1.0.1

Sovereign post-quantum fortification for AgDR records.

Architecture

AgDR-Mantle is the Fortification tier of the AgDR standard. It operates within a three-tier lineage:

• AKI is the Core. Atomic Kernel Inference is the architectural principle defined in the AgDR specification. It is captured at the moment of decision and carries the PPP triplet (Provenance, Place, Purpose).
• AgDR-Phoenix is the Implementation. The reference Rust engine that realizes the AKI Core in running code at sub-microsecond latency, with kernel monotonic timestamps, Byzantine fault tolerance, and the critic pre-filter.
• AgDR-Mantle is the Fortification. It wraps AgDR-Phoenix output with an optional ML-DSA-65 post-quantum envelope, a sovereign sparse Merkle tree witness, and Brotli-compressed forensic archives for Commonwealth and bandwidth-constrained deployments.

+---------------------------------------------------+
|  AgDR-Mantle : FORTIFICATION                      |
|  - ML-DSA-65 (FIPS 204) post-quantum envelope     |
|  - Sovereign Sparse Merkle Tree witness           |
|  - Brotli-compressed forensic archive             |
+---------------------------------------------------+
|  AgDR-Phoenix : IMPLEMENTATION                    |
|  - Rust AKI engine, sub-microsecond latency       |
|  - BFT, critic, PPP capture, kernel timestamps    |
+---------------------------------------------------+
|  AKI : CORE                                       |
|  The architectural invariant. Defined in the      |
|  AgDR specification. Captured at decision time.   |
+---------------------------------------------------+

The Phoenix hot path remains classical Ed25519 and is not modified by Mantle. Mantle runs after Phoenix completes. Its operations therefore do not affect AKI latency.

Features

• Optional ML-DSA-65 (FIPS 204) quantum-resistant signature envelope via the pqcrypto library. Opt-in, disabled by default.
• Sovereign forensic archive using a 256-bit sparse Merkle tree with Brotli compression.
• Self-learning coherence weighting via exponential moving average (feature-gated).
• Designed for Commonwealth, Northern, and other bandwidth-constrained jurisdictions requiring quantum-resistant evidentiary signatures today.

Install

pip install agdr-mantle

# With the post-quantum fortification enabled
pip install agdr-mantle[post-quantum]

# With all optional features
pip install agdr-mantle[post-quantum,self-learning,sovereign]

Quick Start

from agdr_mantle import AgDRMantle

# Classical AKI only (fastest configuration)
engine = AgDRMantle(fo_i="Accountability (Toronto)")

# With ML-DSA-65 post-quantum fortification enabled
engine = AgDRMantle(
    fo_i="Accountability (Toronto)",
    enable_pq=True,
    enable_self_learning=True,
    enable_sovereign=True,
)

ppp = {"provenance": "...", "place": "Toronto, ON", "purpose": "Accountability review"}
sealed_record = engine.seal(ppp)

# Verify the post-quantum fortification envelope
if sealed_record["pq_applied"]:
    envelope = bytes.fromhex(sealed_record["aki_seal"])
    assert engine.pq.verify(envelope)

Post-Quantum Fortification Notes

• Algorithm: ML-DSA-65 (NIST FIPS 204, Security Level 3, 192-bit classical equivalent strength).
• Signature size: 3,309 bytes per envelope.
• Public key size: 1,952 bytes. Private key size: 4,032 bytes.
• Library: pqcrypto v0.4.0 or later. The pqcrypto package wraps the pqclean reference C implementations and ships pre-compiled wheels for common platforms.
• Envelope format: [seal_length][classical_seal][MAGIC][pubkey_length][pubkey][sig_length][signature].
• Keys: ephemeral per-instance by default. Production deployments should inject long-term keys through the pq_keypair constructor parameter.

Performance

Measured on commodity hardware:

Operation	Latency
ML-DSA-65 keygen	around 0.3 ms
Sign and wrap	around 1 ms
Verify	around 0.2 ms

The fortification layer runs downstream of AgDR-Phoenix. The Phoenix hot path latency is unaffected.
