HyperTrade v0.2.0 — Headline Arena External Ground Truth Stream & Autonomous Incubation Loop

HyperTrade v0.2.0 — Headline Arena External Ground Truth Stream & Autonomous Incubation Loop

HyperTrade v0.2.0 introduces an external Ground Truth verification stream by integrating Headline Arena (headlinearena.com) into the Autonomous Research Core (ARC) paper incubation lifecycle, resolving #1.

🌟 Key New Features & Capabilities

• External Ground Truth Stream (Headline Arena):

  • Protocol & Connector (ExternalGroundTruthPort, HeadlineArenaClient, InMemoryGroundTruthClient) supporting macro asset challenge discovery (Gold, Crude Oil, US Treasuries, Equity Indices, Dollar Index).
  • Forward-only blind directional prediction synthesis (synthesize_prediction) from candidate strategy specifications with SHA-256 idempotent submission receipts.
  • Machine settlement against authentic market prices with Brier calibration score synchronization.

• Reflexion Memory & Negative Constraint Injection:

  • Added EXTERNAL_GROUND_TRUTH_DIVERGENCE and EXTERNAL_GROUND_TRUTH_UNAVAILABLE audit reason codes.
  • Strategies exhibiting high simulated performance but divergent forward prediction accuracy (<40%) or elevated Brier error (>0.35) trigger negative constraints (filter_inconsistent_signals_with_external_truth), preventing insular backtest data contamination.

• Attribution & Diagnostic Projections:

  • Dynamically projects external_ground_truth metrics (Brier score, directional accuracy, alignment status) in 7+1 dimensional causal attribution reports.

• Observation Lifecycle & Read-Only Endpoints:

  • sync_external_ground_truth integrated into incubation observation loops.
  • Exposed read-only inspection endpoints: /api/v1/arc/ground-truth/challenges, /api/v1/arc/ground-truth/calibration, /api/v1/arc/ground-truth/evaluate.

• Comprehensive Architecture Documentation:

  • Added Architecture Spec 68: docs/architecture/68-external-ground-truth-stream-and-headline-arena.md.
  • Added contract specification and updated spec.md, progress.md, and READMEs.
