Ingestion Note

This file is the canonical repo capture of the inventor-submitted RWP v3.0 alpha PQC architecture draft shared in-session.

Executive Summary

RWP v3.0 defines a quantum-resistant upgrade path from RWP v2.0 using hybrid post-quantum cryptography while preserving compatibility and Six Sacred Tongues semantic-layer behavior.

Critical driver: harvest-now-decrypt-later risk for long-lifetime sensitive data.

1. Current RWP v2 Baseline and Threat Gap

1.1 Current primitives (v2)

Key exchange: X25519 (vulnerable to Shor)
Signatures: Ed25519 (vulnerable to Shor)
Symmetric: AES-128-GCM (weakened under Grover to ~64-bit effective security)
Hash/MAC/KDF: SHA-256 / HMAC-SHA256 / HKDF-SHA256 (acceptable with Grover caveats)

1.2 Threat model expansion

RWP v2 used a classical Dolev-Yao model without quantum adversaries.
RWP v3 explicitly adds quantum-threat posture and migration controls.

1.3 Six Sacred Tongues crypto-touch points

KO: directive signature integrity (high impact under signature break)
AV: encrypted sentiment payload paths
RU: hash-chain/timestamp integrity
CA: ceremony key operations
UM: derivation and shadow session key lineage
DR: multi-party key agreement and high-authority operations

2. PQC Upgrade Architecture (Hybrid)

2.1 Selected algorithm suite

Function	Classical	PQC	Standard
KEM / Key exchange	X25519	ML-KEM-768	FIPS 203
Signatures	Ed25519	ML-DSA-65	FIPS 204
Symmetric	AES-128-GCM	AES-256-GCM	FIPS 197
Hash	SHA-256	optional SHA3-256	FIPS 202

2.2 Secret-combination policy

Hybrid shared secrets are combined using HKDF over concatenated classical+PQC material; security holds if at least one component remains secure.

3. SST-Aware Negotiation and Policy

3.1 Protocol modes

CLASSICAL_ONLY
HYBRID_PREFER_PQ (default during migration)
PQ_ONLY (target steady-state)

3.2 Mandatory policy constraints

Hybrid KEX required when mode >= hybrid
Hybrid signatures mandatory for critical tongues (KO/CA/DR)
AES-256 minimum for new operations
Key lifetime controls (default max 365d, ceremony max 90d, ephemeral max 24h)
Classical fallback activity must be audit-logged

4. Migration Plan

Phase 1 (Q1-Q2 2026)

Introduce hybrid KEM/signatures in parallel
Upgrade AES-128-GCM -> AES-256-GCM
Enable negotiation framework

Phase 2 (Q3-Q4 2026)

Set hybrid as default
Re-encrypt critical/high-priority historical data
Deprecation warning path for classical-only

Phase 3 (2027+)

Default to PQ_ONLY
Remove classical from active paths
Keep archive verification tooling for historical records

5. API Surface (RWP v3 SDK)

Core abstractions captured in draft:

SpiralverseSDK
Hybrid key exchange methods (generateKeyPair, exchange, encapsulate, decapsulate)
Hybrid signature methods (generateSigningKeyPair, sign, verify, verifyBatch)
SSTManager with tongue-specific bindings (KO/AV/RU/CA/UM/DR)

6. Claimed Operational Outcomes (Draft)

Backward-compatible migration from RWP v2
Hybrid security posture immediately reducing long-horizon risk
Tongue-aware policy governance retained under PQC
Operational path toward pure PQC steady state

8. Relationship to SCBE-AETHERMOORE

This draft aligns with repository components and direction:

six-tongues policy architecture
hybrid/dual-lattice crypto direction
multi-agent governance and audit paths
cloud + edge deployment compatibility requirements

9. Pending Follow-Up

Add compliance matrix mapping each API method to SCBE layer gates.
Add performance benchmark section from measured repo test runs.
Add explicit interoperability test vectors for classical/hybrid/PQ-only transitions.
