Sprint 29 Engineering Log

Program Context

• Phase: Phase 7
• Sprint: Sprint 29
• Status: Completed
• Primary Architecture Layers: C2 Trust Extension Layer, Audit & State Plane

Architectural Intent

Deliver advanced hardened C2 adapters and bind live session execution into verifiable ledger flow.

Implementation Detail

Implemented:

• Hardened Sliver adapter runtime with required command/target controls.
• Mythic adapter scaffold for future command transport expansion.
• Live session orchestration function that persists C2 execution metadata into Merkle ledger leaves.
• Zero-trust live-session enforcement by reusing hardened C2 boundary checks before adapter execution.

Security and Control Posture

• C2 session dispatch is denied unless JWS, policy hash, and execution fingerprint checks pass.
• Adapter-specific session metadata is immutably recorded in the append-only ledger path.
• Live session execution remains bound to policy-approved trust context.

QA and Validation Evidence

• Unit tests cover hardened Sliver behavior, Mythic scaffold behavior, metadata-to-ledger persistence, and zero-trust rejection during forged live sessions.
• Sprint QA checks assert roadmap completion lines and advanced C2 contract presence.

Risk Register

• Risk: adapter scaffold responses are currently simulated and need real transport integration hardening.
• Mitigation: Sprint 30+ broker and streaming phases should include live adapter transport security controls.

Forward Linkage

Sprint 30 integrates broker abstraction and high-throughput streaming for expanded live telemetry flows.
