Sprint 31 Engineering Log

Program Context

• Phase: Phase 8
• Sprint: Sprint 31
• Status: Implemented (Awaiting Signed Commit Promotion)
• Primary Architecture Layers: VectorVue Integration Layer, Orchestration Pipeline, UI Dashboard

Architectural Intent

Implement the bidirectional cognitive feedback loop between SpectraStrike and VectorVue: push execution graph metadata upstream, synchronize actionable feedback downstream, and bind feedback-driven adjustments into policy evaluation context with visible effectiveness metrics.

Implementation Detail

• Added Sprint 31 cognitive loop core module:
  • src/pkg/orchestrator/cognitive_feedback.py
  • FeedbackAdjustment contract for VectorVue-supplied guidance
  • FeedbackPolicyEngine for feedback-bound policy context and allow decisions
  • CognitiveFeedbackLoopService for graph push + feedback sync + policy application
  • defensive effectiveness metric aggregation helpers for reporting/UI
• Extended VectorVue client with cognitive endpoints:
  • send_execution_graph_metadata(...)
  • fetch_feedback_adjustments(...)
• Added UI API contract and dashboard visualization:
  • GET /api/defensive/effectiveness
  • dashboard “Defensive Effectiveness” metric panel
• Added unit and QA coverage for end-to-end cognitive loop behavior.

Security and Control Posture

• AAA scope and authorization boundaries are enforced according to current orchestrator policy.
• Feedback adjustments are explicitly scoped by tenant and target URN.
• Policy adjustments are bound via deterministic in-memory context mapping before decision.
• Integration contracts remain loosely coupled and testable for VectorVue interoperability.

QA and Validation Evidence

Validated through:

• unit tests for VectorVue cognitive client endpoints
• unit tests for cognitive loop service policy binding and effectiveness metrics
• Sprint 31 QA test that exercises full graph push -> feedback sync -> policy deny decision flow

Risk Register

Risk: production drift between local fallback metrics and live orchestrator API data. Mitigation: retain explicit API contract route and keep no-store fetch behavior for runtime refresh.

Forward Linkage

Sprint 32 transitions into compliance mapping and formal control evidence packaging.
