…eferencing Lean hoare-triple library
- Created DafnySpecs directory for clean Dafny-to-Lean port - Moved all .dfy reference files to DafnySpecs/dafny/ - Implemented NpAdd.lean with multiple approaches: - Runtime size checking via hypotheses - Compile-time checking with Vector types - Polymorphic and refinement type variants - MPL-style specification comments for future verification - Includes theorems for commutativity, associativity, and identity
- Implement direct product using fold - Add range-based product matching Dafny's ProdArray specification - Include tail-recursive implementation for efficiency - Add MPL-style specifications for future verification - Provide vector and polymorphic approaches - Include properties like product of ones, zero handling - Add parallel product and zero-check optimizations - Provide Option-based API for safer empty array handling - Add comprehensive examples and test coverage The implementation follows the established patterns from NpAdd.lean and NpSum.lean, providing multiple approaches (runtime constraints, compile-time constraints, refinement types) for array product computation. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
- Add LeanExplore to .mcp.json configuration alongside lean-lsp-mcp - Add MCP setup commands to Justfile (install-mcp-tools, setup-mcp, verify-mcp) - Update setup workflow to include MCP configuration for both CI and local dev - Add automatic installation for lean-lsp-mcp (via uv) and leanexplore (from GitHub) - Include MCP verification in main verify-setup command - Handle optional jq dependency gracefully in MCP commands The MCP tools enable better IDE integration for Lean 4 development: - lean-lsp-mcp: Provides LSP features via Model Context Protocol - leanexplore: Search engine for Lean 4 declarations with AI integration 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
- Update .mcp.json to use correct CLI command: 'leanexplore mcp serve --backend local' - Add demo script showing local search works without API keys - Update documentation with successful local search example - Fix Justfile to use correct MCP command syntax - Ensure data fetch is included in setup process The setup now runs entirely locally: - No API keys required - All searches performed against local database - Privacy-preserving (no external API calls) Demo shows successful search for 'qsort' finding Array.qsort and related functions. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
- Implement arange function with runtime size checking via hypotheses - Add tail-recursive variant for efficiency - Include vector approach with compile-time size calculation - Provide safe Option-based API for invalid parameters - Add specification theorems for first element, consecutive differences, and bounds - Support floating-point ranges with arangeFloat - Include polymorphic version for generic numeric types - Add helper functions like arangeSimple, arangeDefault, and range - Document MPL-style specifications for future verification The implementation follows patterns established in NpAdd, NpSum, and NpMax modules.
Port Dafny np_equal.dfy specification to idiomatic Lean 4: - Element-wise equality comparison returning Array Bool - Runtime size checking via hypotheses matching Dafny requires - Vector-based approach with compile-time size constraints - Polymorphic version for any type with decidable equality - Properties: reflexivity, symmetry, transitivity helpers - MPL-style specifications for future verification - Comprehensive examples and edge case handling Follows established patterns from NpAdd and NpAbs implementations. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
Port np_greater.dfy and np_less.dfy to idiomatic Lean 4 with: - Element-wise comparison operations for arrays with size constraints - Vector-based implementations for compile-time size checking - Polymorphic versions for ordered types with DecidableRel - Properties about ordering (irreflexivity, transitivity) - MPL-style specifications for future verification - Count functions for filtering comparisons Both modules follow established patterns from NpEqual.lean and other DafnySpecs modules. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
