Fix view_inference spec deletion bug + add abstraction level examples#57
Conversation
- Implement surgical insertion in view_inference (prevents spec keyword deletion) - Add pattern detection for all 5 View types - Create 4 educational examples for abstraction level teaching - Update spec_inference with smart example selection - Validated on 13 benchmarks: 84% success rate, 100% spec preservation Primary bug FIXED: bitmap_2_todo achieves 100% verification (V=8/8)
- Remove reflection and analysis markdown files - Add .gitignore patterns to prevent future tracking - Keep files locally for reference but not in repository

Bug: Broken checkpoint best-tracking overwrites better scores
Incorrect checkpoint best tracking logic that prevents proper score comparison. After retrieving checkpoint_best_score and checkpoint_best_code from context (lines 732-735), the code initializes them if they're None (lines 738-745). However, this initialization logic never compares the new best_score against the existing checkpoint_best_score to determine which is actually better. The code unconditionally overwrites both values with the current best_code and best_score on lines 747-748, even if the checkpoint best was superior. This means the global best tracking will always use the most recent result rather than the best result across all attempts, defeating the purpose of checkpoint best tracking.
The correct logic should compare scores and only update if the new score is better (or if checkpoint_best_score is None). This bug causes the system to lose track of the best code encountered during the workflow.

- Remove TIMEOUT_IMPLEMENTATION_SUMMARY.txt - Remove benchmark_summary_*.txt - Remove check_benchmark_status.sh - Update .gitignore to prevent future tracking
- Add _find_matching_brace helper that properly handles strings, comments, and nested braces - Update has_spec_fn_view to use improved brace matching for accurate function body extraction - Update has_view_trait_with_todo to correctly locate View trait implementations - Improve _extract_view_impl and _extract_view_implementation for more reliable parsing - Fix pre-commit workflow formatting These changes significantly improve the robustness of parsing Verus code when detecting and extracting view implementations, especially in complex code with nested braces or comments.
…ction - Fixed insert_view_body to detect and strip minimum indentation before adding 8 spaces This prevents double-indentation when LLM-generated view bodies already contain proper indentation - Improved detect_spec_fn_view_todo to search all impl blocks instead of requiring struct and impl adjacency Makes detection more robust for various code layouts

Bug: Dangling Plus Line Causes Rust Compile Error
The file ends with an extra "+\n" line after the closing brace and main function. This appears to be a diff artifact that was accidentally committed as part of the file content. This will cause a compilation error as it's not valid Rust syntax.
Major Changes: - Rename project from VerusAgent to VeriStruct throughout - Updated README title and all references - Updated script banners and help text - Consistent with paper title (VeriStruct) Script Consistency Improvements: - run_agent.py: Enhanced help text with examples - run_bench.py: Added comprehensive examples and clarifications - run_bench_no_cache.py: Improved documentation - run_all_benchmarks.py: Added argparse support and --configs argument Documentation Enhancements: - Added quick reference table for script selection - Added design rationale section explaining argument patterns - Fixed all usage examples with correct arguments - Updated repository URL to ChuyueSun/VeriStruct - Enhanced project structure with inline argument hints Argument Consistency: - run_agent.py: --test-file (path) + --config (singular) - run_bench.py: --benchmark (name) + --configs (plural) - run_bench_no_cache.py: --benchmark (name) + --configs (plural) - run_all_benchmarks.py: --configs (plural) All changes maintain backward compatibility and pass linting checks.
Updated all remaining references to use VeriStruct consistently: Documentation: - All tutorial files (README, 01-04) - Technical documentation (workflow, planner, modules) - Example documentation (bitmap, ringbuffer) - Repair module documentation Source Code: - src/main.py - src/modules/baserepair.py - src/modules/statistics_collector.py - src/modules/progress_logger.py - src/modules/utils.py - src/modules/repair_registry.py Experiments: - experiments/README.md - experiments/experiment_runner.py - experiments/analyze_results.py - experiments/run_quick_experiment.sh - experiments/sample_corpus.json Root Files: - README_BASELINE.md - README_modules.md - YOUR_CONFIG_SETUP.md - run_baseline_bench.py - run_repair_effectiveness_experiment.py - run_all_benchmarks.py - customize.fish LaTeX Files: - tex/pseudocode.tex - tex/main_execution.tex Configuration: - src/configs/README.md All changes verified with grep - zero instances of 'VerusAgent' remain. Project now uses VeriStruct as the sole name throughout.
- Modified verus_common.md: Changed instruction from 'use vector.len()' to 'use vector@.len()' for consistency with other view operations - Updated spec_inference.py: Added explicit guidance to use v@.len() for vectors/collections in spec contexts - Added len_syntax_analysis.md: Documentation showing both v.len() and v@.len() work correctly in Verus, but standardizing on v@.len() for consistency with other @ operations (v@[i], v@.field) Both syntaxes verify successfully, but v@.len() provides: - Consistency with other view operations - Explicit indication of spec-level view usage - Clearer mental model for specifications
