MidStream Architecture Validation Checklist

Created by rUv Date: October 26, 2025 Status: ✅ VALIDATION COMPLETE

Overview

This checklist provides a comprehensive validation of the MidStream architecture against best practices for Rust workspace management, dependency design, and published crates integration.

1. Workspace Structure ✅

1.1 Organization

  • Workspace root configured - Cargo.toml with [workspace] section
  • Crates directory structure - All crates in crates/ directory
  • Consistent naming - All crates follow kebab-case convention
  • Clear separation - Each crate has single responsibility

1.2 Workspace Configuration

  • Members defined - quic-multistream in workspace members
  • Resolver v2 - Using modern dependency resolver
  • Shared metadata - License, edition consistent across crates
  • No missing crates - All directories have valid Cargo.toml

Score: 8/8 (100%) ✅

2. Dependency Graph Analysis ✅

2.1 Circular Dependencies

  • No circular dependencies - Comprehensive matrix check passed
  • Acyclic graph - All dependencies flow one direction
  • No self-references - Crates don't depend on themselves
  • Valid layer dependencies - Only downward dependencies

2.2 Dependency Layers

  • Layer 1 (Foundation) - 3 crates with 0 internal deps
    • temporal-compare
    • nanosecond-scheduler
    • quic-multistream
  • Layer 2 (Core) - 2 crates depending on Layer 1 only
    • temporal-attractor-studio → temporal-compare
    • temporal-neural-solver → nanosecond-scheduler
  • Layer 3 (Meta) - 1 crate depending on all lower layers
    • strange-loop → all 4 other crates

2.3 Dependency Metrics

  • Foundation independence - Layer 1 has 0 internal dependencies
  • Minimal coupling - Average 1.0 internal deps per crate
  • Clear hierarchy - 3 distinct layers
  • Proper encapsulation - No cross-layer violations

Score: 11/11 (100%) ✅

3. Published Crates Strategy ✅

3.1 Publishing Readiness

  • Metadata complete - All crates have name, version, edition, license
  • Version consistency - All at v0.1.0
  • License specified - MIT for all crates
  • Description present - All crates have descriptions
  • No private data - No hardcoded secrets or credentials

3.2 Hybrid Approach

  • Published crates identified - 5 crates ready for crates.io
    • temporal-compare
    • nanosecond-scheduler
    • temporal-attractor-studio
    • temporal-neural-solver
    • strange-loop
  • Local development crate - quic-multistream kept local
  • Clear rationale - Published = stable, Local = active dev
  • Phased publishing - Phase 1 → 2 → 3 approach

3.3 Dependency Configuration

  • Root uses published versions - temporal-compare = "0.1"
  • Caret requirements - Allows patch updates ^0.1
  • Local path for dev crate - quic-multistream = { path = "..." }
  • No version conflicts - All published crates at 0.1

Score: 13/13 (100%) ✅

4. Feature Flags Configuration ⚠️

4.1 Current State

  • Feature flags defined - Not yet implemented
  • Default features - Not configured
