SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill helps you analyze systems where values are not simply equal, greater, or smaller, but may be partially ordered or incomparable. It is especially useful when merges, compatibility checks, permissions, type relations, or concurrent states behave incorrectly because the underlying order has been modeled too crudely.

Core Features & Use Cases

  • Partial Order Analysis: Verifies whether a domain truly forms a poset by checking reflexivity, antisymmetry, and transitivity.
  • Join and Merge Design: Helps define joins, meets, bottom, and top elements for lattices used in CRDTs, type systems, version compatibility, and permission models.
  • Monotonicity and Termination Checks: Evaluates whether operations are monotone and whether lattice-based algorithms will terminate or require widening.
  • Use Cases: Diagnose broken CRDT convergence, design safer permission hierarchies, reason about subtype lattices, model schema or protocol compatibility, and structure dataflow or abstract interpretation analyses.

Quick Start

Ask the skill to analyze your domain's order relation, identify incomparable cases, and define a valid join for your merge or compatibility logic.

FAQPage Schema
How do I define a valid join for CRDT merge logic when concurrent updates conflict?

Diagnosing broken CRDT convergence requires verifying that your domain forms a poset with valid algebraic merge properties. The skill checks reflexivity, antisymmetry, and transitivity, identifies incomparable elements, and defines valid joins to ensure monotone operations and correct concurrent state merges.

What is a partially ordered domain and when do I need poset verification for type systems?

A partially ordered domain contains elements that may be incomparable rather than strictly greater or smaller. You need poset verification for type systems when modeling subtype lattices or permission hierarchies, ensuring that reflexivity, antisymmetry, and transitivity hold before defining joins and meets.

How do I check monotonicity and lattice termination conditions for dataflow analysis?

Checking monotonicity and lattice termination for dataflow analysis involves evaluating whether operations preserve order and verifying chain conditions. The skill analyzes your lattice structure to determine if algorithms will terminate naturally or require widening techniques for abstract interpretation workflows.

Can I model version compatibility and schema evolution using lattice structures?

You can model version compatibility using lattice structures by defining bottom and top elements to represent boundaries. The skill helps map protocol compatibility across partially ordered versions, identifying incomparable releases and defining joins for safe schema merges and backward compatibility checks.

How do I handle incomparable elements in vector clocks for concurrent state synchronization?

Handling incomparable elements in vector clocks requires explicit partial order analysis rather than simple equality checks. The skill identifies incomparable concurrent states, verifies poset laws, and defines algebraic merge properties to structure dataflow and synchronization workflows correctly.

Why does my permission hierarchy merge incorrectly and how do I fix the lattice structure?

Permission hierarchy merges fail when the underlying order is modeled too crudely without valid joins. The skill analyzes your partially ordered permission domain, verifies antisymmetry and transitivity, and defines precise bottom and top elements to fix broken hierarchy convergence.
