SYNTHESIS BRIEF

Version: v27.0

v27.0 Synthesis Brief

For: t_v27_007 Cycle Synthesis and v28 Recommendations From: t_v27_0 Coordinator Date: 2026-06-05

Purpose

Synthesize all v27.0 research streams into a definitive cycle report and generate v28 recommendations.

Inputs (all in GourmetVault/v27.0/)

Completed Reports

1. v27_001_data_infrastructure.md — Firecrawl restoration, entity verification pipeline, daily reporting fix, Brier scores
2. v27_002_methodology_hardening.md — Single epoch system, Convergence Calendar V5, structural window classification
3. v27_003_model_improvements.md — Living Oracle decay, regime training, TGN daily, 3-model ensemble

Pending Reports (from running tasks)

4. v27_004_entity_oracle_v7.md — Entity expansion 105→120 (completion task t_306948c9 spawned)
5. v27_005_earth_air_phase7.md — Earth-Air bridge 0.91→0.97 (t_v27_5 running)
6. validation_dashboard_v27.html — Mobile responsive dashboard (t_v27_6 running)

Key Data Files

• predictions/v27_003_results.json — Model improvement metrics
• predictions/convergence_calendar_v5.json — 579-day forecast
• predictions/brier_scores_2026-06.json — June Brier scores
• predictions/entity_verification_2026-06-10.json — Entity verification data

Synthesis Requirements

I. Executive Summary

• One-page overview of v27.0 achievements vs targets
• Metric comparison table: v26.0 → v27.0

II. Per-Stream Synthesis

For each of the 6 research streams:

• What was attempted
• What was achieved
• Key metrics and deltas from v26.0
• Unexpected findings

III. Cross-Stream Analysis

• How do the model improvements interact with methodology hardening?
• Does entity expansion improve Earth-Air bridge pathways?
• What’s the combined effect on prediction quality?

IV. Metric Scorecard

V. v28 Recommendations

Based on v27.0 results, recommend:

1. Top 3 priorities for v28
2. Methodology changes needed
3. New research directions
4. Infrastructure improvements

VI. Publication

• Write cycle report to GourmetVault/v27.0/reports/v27_007_cycle_synthesis.md
• Update public repo if warranted
• Generate executive summary for Substack Oracle
