Unreleased

🔬 Physics Kernel

  • 57 machine-checkable invariants across 15 modules (PR #138, #139)
  • 67 mathematical witness tests with INV-* references and 5-field error messages
  • Physics Kernel CI Gate: self-check + L1-L5 validation + C1/C2 code audit
  • C1/C2 code audit: 69 → 5 silent clamps (0 physics), 0 undocumented bounds
  • 3 physics-law corrections: RC1, FE2, OMS1 falsified and corrected by witnesses
  • Gradient Constitution (CLAUDE.md §0): maintenance hierarchy, INV-YV1

🧬 New Modules

  • Cryptobiosis (core/neuro/cryptobiosis.py): phase-transition survival, 8 invariants (CB1-CB8)
  • physics_contracts/: parallel law-catalog with @law() decorator and AST validator

🚀 Features

  • DOC PR COPILOT v2: LLM-based documentation agent for automated documentation review and patch generation in Pull Requests.
  • Agent configuration system in .github/agents/ with system prompts, integration guides, and examples.
  • 4C Principles documentation (Clarity, Conciseness, Correctness, Consistency) for documentation standards.
  • Comprehensive API documentation (docs/API.md) with Python, CLI, and HTTP endpoint references.
  • Release readiness assessment with comprehensive quality gates and metrics

⚡ Performance

  • Refactored cache key normalisation to use deterministic repr tuples, improving synthetic throughput by ~19%.
  • Benchmarks show 48-74% performance improvements over baseline across core indicators

🧹 Maintenance

  • Hardened Release Drafter automation (v6 workflow, semantic version resolver, metrics summary).
  • Repository cleanup: verified all temporary artifacts properly gitignored
  • Comprehensive release readiness report (reports/RELEASE_READINESS_REPORT.md)

✅ Quality Assurance

  • 351 core tests passing (100% pass rate)
  • 683 source files with zero type errors (mypy)
  • Zero critical security vulnerabilities
  • 30+ GitHub Actions workflows for comprehensive CI/CD

⚠️ Breaking Changes

  • Systems with non-deterministic __repr__ implementations on cache keys should validate behaviour after the cache refactoring.

2.1.3 - 2025-10-05

🚀 Features

  • New CI/CD pipelines: ci.yml (lint/test matrices, concurrency, caches), pre-commit.yml, auto-merge.yml, sbom-scan.yml, publish-image.yml (cosign), data-sanity.yml.
  • Quality management: benchmarks.yml, integration.yml, commitlint.yml, pr-labeler.yml, todo.yml.
  • Contract validation: buf.yml (lint+breaking), gen-drift.yml (+ Makefile generate).

🧹 Maintenance

  • Updated .pre-commit-config.yaml (black, ruff, prettier, buf hooks).
  • Adapted JS gateway (domains/platform/gateway) for lint job.

2.1.2 - 2025-10-05

🚀 Features

  • Pre-commit config (.pre-commit-config.yaml), pytest config (pytest.ini).
  • GitHub templates: issue/PR, labeler, dependabot, release-drafter.
  • CI workflows: release-drafter, codeql, lint, test-matrix, docs-build, deploy, infra-check.
  • Automation scripts expansion (scripts/*).
  • Process templates: .gitattributes, CODEOWNERS, CONTRIBUTING.md, CODE_OF_CONDUCT.md.

📝 Documentation

  • Clarified documentation on Fractal Modular Architecture (FPM-A).

2.1.1 - 2025-10-05

🚀 Features

  • Integrated professional project artifacts: .gitattributes, CONTRIBUTING.md, CODE_OF_CONDUCT.md, CHANGELOG.md, CODEOWNERS.
  • Added Python package scripts with unified CLI (python -m scripts).

🔐 Security

  • Unified file line endings via .gitattributes.

2.1.0 - 2025-10-05

🚀 Features

  • FPM-A Integration: Fractal units, dependency graphs, cyclomatic complexity metrics, CI gates.

2.0.0 - 2025-10-05

🚀 Features

  • Initial GeoSync skeleton: protobuf contracts, Python/Next.js scaffolding, infrastructure files.

0.1.0 - 2025-10-05 — Initial Public Preview

🚀 Features

  • Core Indicators: Kuramoto oscillators, Ricci flow curvature, Shannon entropy, Hurst exponent, 50+ technical indicators.
  • Market Phase Detection: Five-phase classification (CHAOTIC, PROTO_EMERGENT, STRONG_EMERGENT, TRANSITION, POST_EMERGENT).
  • GeoSyncCompositeEngine: High-level API combining Kuramoto synchronization with Ricci flow geometry.
  • Event-Driven Backtest Engine: Walk-forward testing, Monte Carlo simulation, transaction cost modeling.
  • CLI Interface: analyze, backtest, live commands with JSON output and tracing.
  • Streamlit Dashboard: Interactive market analysis and visualization.
  • Fractal Modular Architecture (FPM-A): Clean domain separation with ports/adapters pattern.

📝 Documentation

  • README with quickstart, feature overview, and architecture diagrams.
  • MkDocs documentation site structure.
  • API reference, quickstart guide, deployment docs.

🔐 Security

  • CodeQL scanning, SBOM generation, secret detection.
  • Security framework aligned with NIST SP 800-53 and ISO 27001.

🐛 Fixes

  • Filled template placeholders in CLI/scripts.
  • Synchronized versioning and configs.

⚠️ Known Limitations

  • Live trading is in beta; test thoroughly in paper mode before production.
  • Web dashboard is in early preview (alpha).
  • Some advanced indicators require optional dependencies (pip install ".[neuro_advanced]").
