Added tarpaulin.toml configuration - Configured HTML, LCOV, and stdout reports - Created coverage scripts (PowerShell and Bash) - Added coverage outputs to .gitignore - Target: 80% coverage for v0.0.2 Note: cargo-tarpaulin installation in progress * docs: migrate from tarpaulin to llvm-cov for coverage - Added COVERAGE_SETUP_NOTES.md documenting Windows file locking issues - Updated coverage scripts to use cargo-llvm-cov instead of tarpaulin - llvm-cov provides better Windows compatibility - Both PowerShell and Bash scripts updated - Installation of llvm-tools-preview and cargo-llvm-cov in progress * docs: add comprehensive test coverage analysis - Created TEST_COVERAGE_ANALYSIS.md with manual gap analysis - Identified 96 existing tests across workspace - Documented 10 high-priority test gaps to address - Listed 8 medium and multiple low-priority improvements - Estimated current coverage at 65-70% line coverage - Updated LEARNINGS.md with coverage tooling challenges - Documented that coverage tools have Windows compatibility issues - Plan: Manual analysis locally, tarpaulin in Linux CI Target for v0.0.2: 80% line coverage via edge case testing * test: add 20 high-priority edge case tests Added comprehensive edge case tests based on manual coverage analysis: Lexer Tests (10 new, all passing): - Comments-only files - Large numbers (max/min/small values) - Very long identifiers (1000 chars) - Unicode identifiers - Mixed comments and code - Empty string literals - Multiple dots (potential float parsing edge case) - Consecutive operators Runtime Tests (10 new, all passing): - Division by zero (documents current behavior) - Integer overflow handling (large arithmetic) - Deeply nested expressions (100 levels) - Recursion depth (100 levels with countdown) - Short-circuit AND evaluation - Short-circuit OR evaluation - Variable shadowing (function-level) - Empty function bodies - Early returns from nested blocks - Large arrays of expressions (50 statements) Test Coverage Impact: - Total tests: 96 → 116 (+20, +20.8%) - All new tests passing - Estimated coverage improvement: +5-10% line coverage - Tests document current runtime limitations and behaviors Discoveries from testing: - Large integer literals parsed as f32 (lexer limitation) - Bare blocks {} not yet supported in parser - Global mutable variables need more work - Division by zero produces undefined behavior (not proper error) - Recursion works well up to 100+ levels - Deep expression nesting handled correctly These tests establish baseline behavior and identify areas for future improvement in error handling and edge case support. * docs: document edge case testing insights in LEARNINGS.md Added detailed section on edge case test implementation covering: - Lexer limitations (large literal parsing as f32) - Parser limitations (no bare block support) - Runtime behavior discoveries (division by zero, overflow) - Global mutable variable limitations - Runtime strengths (deep nesting, recursion) - Testing strategy insights These learnings will guide future improvements to error handling, lexer refinement, and parser feature additions. * perf: add criterion benchmarks and establish baseline metrics Added comprehensive benchmarking infrastructure using criterion.rs: Compiler Benchmarks: - Lexer: 384 ns (small) to 3.74 μs (large) - Parser: 600 ns (small) to 7.94 μs (large) - Type checker: 851 ns (small) to 3.58 μs (medium) - Full pipeline: ~3.6 μs for medium function Runtime Benchmarks: - Simple arithmetic: ~1.05 μs per function call - Control flow (if/else): ~1.31 μs - Loop iterations: ~180 ns per iteration (steady-state) - Recursion: ~925 ns per call (consistent across depths) - Variable operations: ~370-510 ns per operation - Integer arithmetic: ~850 ns per operation - Float arithmetic: ~830 ns per operation - Boolean logic: ~450 ns per operation Performance Analysis: - Compilation: ~278K functions/sec - Execution: ~16K function calls per frame at 60 FPS - Scaling: Linear across all components - Bottleneck: Function call overhead (~1 μs) Documentation: - Created BENCHMARK_BASELINE.md with detailed metrics - Includes performance summary and optimization targets - Documents reproducibility and future optimization plans - Provides Godot integration performance considerations Verdict: Current performance is excellent for game scripting workloads. Over 16,000 function calls per frame at 60 FPS is more than sufficient for typical Godot 4 scripting scenarios. * docs: update v0.0.2 checklist with code quality completion Marked completed items from feature/code-quality-improvements: Testing: - ✅ Manual test coverage analysis (TEST_COVERAGE_ANALYSIS.md) - ✅ 20 new edge case tests (96 → 116 tests, +20.8%) - ✅ Coverage improvement: 65-70% → 70-75% estimated - ✅ Documented Windows coverage tooling challenges Performance: - ✅ Criterion benchmarks for all compiler + runtime components - ✅ Baseline metrics established (BENCHMARK_BASELINE.md) - ✅ Performance analysis: 16K+ calls/frame at 60 FPS - ✅ Identified optimization targets Next steps: - CI-based coverage reporting (Linux tarpaulin) - Continue toward 80%+ coverage - Profile and optimize hot paths * docs: comprehensive coverage documentation and checklist updates

* feat: v0.0.3 infrastructure - branching workflow and CI optimization (#22) * feat: implement v0.0.3 branching workflow and CI optimization - Create develop branch for integration testing - Add quick-check CI for feature branches (2-3 min) - Add path filters to skip CI for docs-only changes - Update CONTRIBUTING.md with new workflow documentation - Update PR templates to reference develop as base branch - Prepare for branch protection setup on main/develop Benefits: - 60-70% CI time savings on feature branches - 95% savings on docs-only PRs - Integration testing before production release - Clearer development workflow Refs: docs/planning/v0.0.3-roadmap.md (Development Workflow) Refs: docs/archive/v0.0.2/V0.0.2_DEFERRAL_ANALYSIS.md (CI optimization) * fix: replace approximate PI value with non-constant float in test Changed test value from 3.14 to 3.5 to avoid clippy::approx_constant warning. The test is verifying float value coercion, not mathematical constants. * docs: move comprehensive testing guide for v0.0.2 * chore: improve CI behavior documentation for branch workflows * feat: rename code scanning workflow with SonarQube integration * fix: resolve all clippy lint warnings in tests - Replace 3.14 with 3.5 in lexer test (avoids approx_constant lint) - Replace assert_eq! with assert! for boolean comparisons in parser tests - Remove assert!(true) placeholder in godot_bind tests (replace with comment) * fix(ci): pin Rust toolchain version for consistency * fix: prevent duplicate CI runs and improve clippy documentation - Remove feature/** from push triggers to prevent duplicate runs when PR exists - Simplify quick-check condition to only run on pull_request events - Update CONTRIBUTING.md to use full clippy command (--all-targets --all-features) - Fix rust-toolchain action configuration in quick-check job This resolves the issue where pushing to a feature branch with an open PR would trigger both push and pull_request events, running CI twice. * fix(docs): update relative links in TESTING.md for accuracy * fix: exclude docs/archive folder from markdown link checking Archive documentation may contain outdated or moved links that don't need to be validated in CI. This change adds a step to find markdown files while excluding the archive folder, target directory, and node_modules. Also excludes target/ and node_modules/ to avoid checking build artifacts. * fix: properly exclude all archive subdirectories from link checking The previous pattern './docs/archive/*' only matched files directly in the archive folder, not in subdirectories like 'docs/archive/v0.0.2/phases/'. Changed to '*/docs/archive/*' to match any path containing docs/archive, which properly excludes all 43 markdown files in the archive directory tree. This resolves the Status: 400 errors from archived documentation with relative links that no longer resolve correctly. * fix: run markdown-link-check directly with explicit file filtering The github-action-markdown-link-check action was running its own find command that ignored our filtered file list, causing it to check archive files despite our exclusion logic. Changed approach: - Install markdown-link-check directly via npm - Run find with explicit archive exclusion in the command - Remove dependency on third-party action for better control This ensures archive files are truly excluded from link checking. * docs: update workflows README for v0.0.3 infrastructure changes Comprehensive update to reflect all CI optimizations: New Features Documented: - Quick Check job (2-3 min fast PR feedback) - Path filters for docs-only changes (95% savings) - Three-branch workflow (main/develop/feature) - Archive exclusion in link checking Updated Sections: - Available Workflows: Added quick-check, updated all triggers - Job Details: Complete rewrite with v0.0.3 conditions - Performance Metrics: New timing table with 70% savings analysis - Event Flow Examples: 5 new examples covering all scenarios - Troubleshooting: Added v0.0.3-specific issues Benefits Highlighted: - 60-70% faster PR feedback (2-3 min vs 10-15 min) - 95% savings on docs PRs (CI skipped entirely) - 70% overall CI cost reduction - Prevented duplicate runs on feature branches All documentation now matches actual ci.yml and docs-lint.yml behavior. * feat(errors): implement comprehensive error code system (E001-E418) (#27) * feat(errors): implement comprehensive error code system (E001-E418) Phase 1 of v0.0.3 - Error Code System - Add ErrorCode enum with 55 variants across 5 categories: * Lexical errors (E001-E003) * Syntax errors (E100-E113) * Type errors (E200-E219) * Runtime errors (E400-E418) * Internal errors (E900-E999) - Implement error code formatting infrastructure - Update all compiler errors with structured codes: * Lexer: 6 errors → E001-E003 * Parser: 14 errors → E100-E113 * Type Checker: 19 errors → E200-E219 * Runtime: 24 errors → E400-E418 - Create comprehensive ERROR_CODES.md documentation (63 codes) - Add 9 error code validation tests - Fix documentation links in planning documents All 222 tests passing.

Simplify README.md (280 → 100 lines): Keep purpose, when to use, quick start - Simplify PR_TEMPLATE_SYSTEM.md (308 → 80 lines): Reference card only - Delete QUICK_REFERENCE.md (230 lines): Fully redundant with main prompt - Net result: -69% supplementary docs, +4% main prompt (1,066 lines) Incorporate deferred work into version roadmaps: - v0.0.4: Prompt testing, link checking automation (high priority) - v0.0.5: Pre-flight script, LEARNINGS generator, LSP quick fixes - v0.1.0+: Phase-specific prompts, telemetry, localization Addresses feedback from Phase 3C execution: - Dates often incorrect (defaulting to January) - TODO list updates inconsistent - Version-specific references in generic template - LEARNINGS.md updates not emphasized enough - Link checking coverage unclear - Deferred work recommendations integrated into roadmaps - Fragmented documentation across multiple files (consolidated) * fix: clean up formatting and improve clarity in documentation files * docs: move Prompts Folder Consolidation Analysis for improved Copilot usability * docs: Add type promotion research and post-v0.1.0 roadmaps - Created TYPE_PROMOTION_RESEARCH.md with comprehensive analysis: - Analyzed 6 game engines (Godot, Unity, Unreal, Bevy, Lua, JavaScript) - Compared 4 type promotion strategies - Documented performance implications and FFI considerations - Confirmed current i32/f32 approach is correct and Godot-compatible - Updated academic paper references with actual links - Created v0.2.0-roadmap.md (PROPOSED): - Extended type system (i64, f64, i16, u8, u16) -

Create PROMPT_OPTIMIZATION_RESEARCH.md analyzing GitHub Copilot premium request optimization - Key insight: Optimize for requests per feature, not tokens per request - Analyze 8 optimization strategies with impact ratings and estimated savings - High-impact strategies: clarification minimization, plan+execute fusion, deterministic completion - Medium-impact strategies: self-validation loop, error recovery, context pre-loading - Expected outcome: Reduce from 2-4 requests per feature to 1-1.5 requests (50-75% savings) - Provide 3-phase implementation roadmap (high-impact → risk mitigation → polish) - Define success metrics: quantitative (requests per feature) and qualitative (user experience) Also fix markdown linting issues in MARKDOWN_SYNTAX_HIGHLIGHTING_RESEARCH.md: - Convert emphasized text to proper headings (MD036) - Option A and Option B are now proper level 4 headings * feat(prompts): Implement Groups 1-2 of premium request optimizations Group 1: Foundation + High-Impact Core - Add Ambiguity Resolution Strategy section - Self-resolve low-risk ambiguities with documented assumptions - Only ask for high-risk decisions (API changes, security, data loss) - Expected savings: 1 request per feature (50% reduction) - Add Definition of Done section - Explicit completion checklist (code, docs, validation, output) - Clear DO NOT/ALWAYS lists for completion behavior - Required completion marker: '✅ Workstream Execution Complete' - Expected savings: 0.5-1 request per feature - Enhance Context Pre-Loading section - Full FerrisScript project identity and structure - Code and documentation conventions - Branch naming, commit format, quality standards - Test commands and CI/CD pipeline details - Version discovery (removed hardcoded versions, use docs/planning/) - Expected savings: 0.25-0.5 request per feature Group 2: Execution Flow Changes - Update Execution Planning section - Default: Brief plan (≤5 bullets) + immediate execution - No approval required for clear requirements - Fallback to explicit planning only if genuinely unclear - Expected savings: 1 request per feature (50% reduction) - Add Forward Progress Mandate section - Always make forward progress unless critically ambiguous - Make reasonable inferences, document assumptions - Only stop for high-risk ambiguities - Example scenarios with old vs new behavior - Expected savings: 0.5 request per feature - Add Self-Correction + Validation Loop section - 4-phase validation: syntax, tests, quality, links - Full license to fix code issues (no attempt limits) - Only stop when: validation passes, exhausted reasonable fixes, or tool is broken - Tool failure limit: 3 crashes (tool itself broken, not code) - Expected savings: 0.5-1 request per feature Total Expected Impact: Reduce from 2-4 requests/feature to 1-1.5 requests/feature (50-75% savings) Fixes based on review: - Remove hardcoded version numbers (v0.0.3, v0.1.0), use dynamic discovery from docs/planning/ - Clarify validation retry logic: unlimited code fix attempts, only limit tool crashes * feat(prompts): Implement Group 3 - Polish and Optional Features Group 3a: Hierarchical Output Structure (Strategy 5) - Add 'Required Output Structure' section with 7 standardized sections - Section 1: Executive Summary (goal, context, approach, assumptions) - Section 2: Implementation (files created/modified, key changes, code highlights) - Section 3: Documentation (created/updated, link validation results) - Section 4: Testing (tests added, execution results, coverage impact) - Section 5: Validation (build status, linting status, acceptance criteria) - Section 6: Post-Execution Notes (decisions, assumptions, recommendations, limitations) - Section 7: Completion Marker (deliverables summary, validation status, next action) - Benefits: Easy to scan, no ambiguity, evidence provided, reduces follow-up questions - Expected savings: 0.25 request per feature Group 3b: Execution Mode Toggle (Strategy 6) - Add 'Execution Modes' section with 3 modes: full, plan, execute - Mode 'full' (default): Plan + Execute + Document + Test in one pass - Mode 'plan': Only create execution plan, no implementation (exploratory) - Mode 'execute': Skip planning, proceed directly to implementation - Mode detection: Auto-detect from user language or explicit mode parameter - Usage: /prompt #file:workstream-execution.prompt.md mode=[mode] - Benefits: Flexibility for different scenarios, control over premium request usage - Expected savings: 0 (flexibility feature, not optimization) Total Group 3 Impact: +0.25 requests savings + improved UX clarity Note: Both sections in same file, staged together. Hierarchical Output Structure is higher priority (improves clarity), Execution Mode Toggle is optional (adds flexibility). All 8 optimization strategies now implemented: ✅ Strategy 1: Clarification Minimization (HIGH - Group 1) ✅ Strategy 2: Plan + Execute Fusion (HIGH - Group 2) ✅ Strategy 3: Deterministic Completion (MEDIUM-HIGH - Group 1) ✅ Strategy 4: Self-Correction + Validation (MEDIUM - Group 2) ✅ Strategy 5: Hierarchical Output Structure (LOW-MEDIUM - Group 3) ✅ Strategy 6: Execution Mode Toggle (LOW - Group 3) ✅ Strategy 7: Error Recovery Directive (MEDIUM - Group 2) ✅ Strategy 8: Context Pre-Loading (MEDIUM-HIGH - Group 1) Total Expected Impact: 50-75% reduction in premium requests (from 2-4 to 1-1.5 per feature) * fix(prompts): Clarify version planning discovery logic Clarify that active roadmap is the LOWEST version number, not highest: - Roadmaps are built outwards (plan future while working on earliest version) - Example: v0.2.0, v0.3.0, v0.4.0 exist → active work is v0.2.0 (lowest = current) - Higher-numbered roadmaps are forward planning, not current work - Add explicit 'Why lowest' explanation to prevent misinterpretation This ensures Copilot correctly identifies the current active version when multiple roadmaps exist in docs/planning/. * feat(vscode): Phase 4 - Code Completion Provider (v0.0.3) (#37) * feat(vscode): Add code completion provider for FerrisScript (Phase 4) Implement context-aware completion for keywords, types, and functions in VS Code extension. Features: - Keyword completion: let, mut, fn, if, else, while, return, true, false - Type completion: i32, f32, bool, String, Vector2, Node, void - Function completion: print with parameter hints - Context-aware suggestions: - Type position (after ':') shows only types - Statement start shows statement-level keywords - Expression context shows all keywords + functions - Snippet support for structured code insertion Technical Implementation: - TypeScript-based extension infrastructure (tsconfig, npm scripts) - CompletionItemProvider using VS Code API - Regex-based context detection - Comprehensive documentation with examples - Manual testing guide for validation Documentation: - PHASE_4_VS_CODE_COMPLETION.md: Full implementation plan - PHASE_4_MANUAL_TESTING.md: Testing guide with 10 test scenarios - Extension README and CHANGELOG updated - v0.0.3 roadmap documents aligned - LEARNINGS.md updated with Phase 4 insights References: - Phase 4 Document: docs/planning/v0.0.3/PHASE_4_VS_CODE_COMPLETION.md - Testing Guide: docs/planning/v0.0.3/PHASE_4_MANUAL_TESTING.md - Roadmap: docs/planning/v0.0.3/README.md - v0.0.3 Roadmap: docs/planning/v0.0.3/v0.0.3-roadmap.md Phase: 4 of 9 in v0.0.3 (Editor Experience Alpha) Status: Complete - Ready for manual testing and PR * style(docs): Fix markdown linting in Phase 4 documentation * fix(vscode): Address Phase 4 feedback - version, linting, docs Fixes: - Update extension version to 0.0.3 (aligns with completed work) - Remove redundant activationEvents (VS Code auto-generates from contributes) - Create extensions/vscode/.gitignore (exclude node_modules, out/, *.vsix) - Exclude extensions/vscode/node_modules from markdown linting Documentation: - Add TYPE_SYNC.md: comprehensive type synchronization guide - Documents manual sync requirements - Proposes validation scripts (v0.0.4) - Proposes type generation automation (v0.1.0+) - Plans LSP-based dynamic types (v0.0.5) - Update v0.0.3-roadmap.md: add Post-v0.0.3 Recommendations section - Type synchronization timeline - Build automation (local dev, CI/CD, release) - VSIX distribution strategy - Update README.md: - Add VSIX installation instructions - Add type completion maintenance section - Document extension activation behavior - Add architecture notes - Update CHANGELOG.md: promote v0.0.3 Phase 4 to released Rationale: - TypeScript compilation working (error was VS Code cache issue) - activationEvents removed per VS Code best practices (1.75+) - node_modules properly excluded from git and linting - Comprehensive documentation for future type synchronization - Clear roadmap for build automation and VSIX distribution * docs(prompt): Add Phase 4 learnings and GitHub CLI best practices GitHub CLI Documentation: - Create GITHUB_CLI_PR_CREATION.md with 3 solutions for backtick escaping - Recommend --body-file approach as standard (avoids shell interpretation) - Document PowerShell/Bash differences and workarounds - Include PR template examples and automation helpers - Provide lessons learned from Phase 4 PR creation issue Prompt Improvements Documentation: - Create PROMPT_IMPROVEMENTS_PHASE4.md analyzing Phase 4 execution - Document 6 issues that needed correction: 1. GitHub CLI backtick escaping (PR corruption) 2. Version misalignment (0.1.0 vs 0.0.3) 3. Missing .gitignore (node_modules tracked/linted) 4. Redundant activationEvents (deprecated VS Code practice) 5. TypeScript error communication gap (cache issue) 6. Reactive documentation (type sync, build automation, VSIX) - Provide 7 prompt improvement recommendations: 1. GitHub CLI best practices (--body-file) 2. Version alignment verification 3. Standard project files checklist 4. Proactive maintenance documentation 5. VS Code extension best practices (2024+) 6. Discrepancy investigation protocol 7. Automation decision framework - Define success metrics and validation approach Rationale: - Phase 4 revealed patterns where Copilot was reactive vs proactive - Backtick issue was most visible problem (corrupted PR description) - Documentation improvements prevent repeat issues in future phases - Framework helps decide when to automate vs document vs roadmap Impact: - Future phases should anticipate maintenance needs proactively - PR creation will use reliable --body-file approach - Standard files (.gitignore, package.json) created upfront - Version context verified before setting versions References: - Phase 4 execution: 3 commits, 6 feedback items, 1 PR failure - Phase 5 target: 2 commits, ≤2 feedback items, 0 failures - Phase 6+ goal: 1 commit, 0 corrections, 100% smooth * exclude markdownlint rule M037 * docs: Apply Phase 4 prompt improvements Implement 7 prompt improvements identified during Phase 4 execution to keep them contextually close to when the work was done.

Missing LICENSE - Copied: LICENSE → extensions/vscode/LICENSE - Satisfies vsce package requirements Result: Successfully packaged as ferrisscript-0.0.3.vsix (48 files, 879.95KB) Installation: Extension installed via 'code --install-extension ferrisscript-0.0.3.vsix' This should resolve the icon theme caching issue - fresh VSIX package = fresh install. * fix(vscode): Remove icon theme - fundamental misunderstanding of VS Code icon system Issue: Icon theme replaced ALL file icons, not just .ferris files Root Cause: Icon themes are COMPLETE icon sets (like Seti, Material Icons) - Must define icons for hundreds of file types - Cannot add single file icon without defining all others - When selected, replaces ALL file icons in VS Code Resolution: Removed iconThemes contribution from package.json - Removed: contributes.iconThemes section - Kept: All other features (hover, completion, diagnostics) - Updated: CHANGELOG.md to remove file icon mention - Updated: PHASE_5_MANUAL_TESTING.md Test 13 status Why This Is Correct: 1. Language extensions (Rust, Python, Julia) don't ship icon themes 2. File icons are managed by dedicated icon theme extensions 3. Icon themes require defining icons for ALL file types 4. Not feasible for single-language extension Impact: - .ferris files will use default file icon from active icon theme - All other extension features (hover, completion, diagnostics) unaffected - Extension now follows VS Code best practices Testing: Packaged and installed - 'FerrisScript Icons' no longer appears in icon theme list Acceptance Criteria Update: 7/10 met (removed infeasible criterion) * docs: Add icon theme lesson learned to LEARNINGS.md Documented complete analysis of icon theme misunderstanding: - Why icon themes are complete replacements, not augmentations - Technical details of VS Code icon system architecture - Why we can't use icon themes for single file type - How other language extensions handle this (they don't ship icon themes) - Alternative approach: Submit PRs to popular icon theme extensions - Recommendations for future development Key Takeaway: Icon themes must define ALL file types. Language extensions should focus on core features (hover, completion, diagnostics) and leave icons to dedicated icon theme extensions. * docs: Add Phase 5 PR description and summary Comprehensive PR documentation including: - Feature overview (hover tooltips, diagnostic infrastructure) - Testing results (9/15 passing, 5 N/A, 1 removed) - Issues resolved (icon theme, VSIX packaging, CLI limitation) - Documentation created (6 new files, 4 updated) - Deferred work (CLI implementation, LSP server) - Acceptance criteria status (7/10 met) - Deployment instructions and verification checklist Ready to create PR: feature/v0.0.3-phase-5-hover → develop * docs: Add Phase 5 completion summary Final summary document including: - All accomplishments and deliverables - Testing results and acceptance criteria - Key lessons learned (icon theme, VSIX, CLI) - Statistics (23 files, +2,935 lines) - Deferred work and priorities - PR details (#38) - Success metrics and next steps Phase 5 complete: Hover tooltips working, diagnostic infrastructure ready, extension packaging working, comprehensive documentation created. * docs: Update Phase 5 documentation and testing guides to reflect icon theme removal and fixes * security(vscode): Fix command injection vulnerabilities in diagnostic provider Fixed 2 security hotspots: 1. findCompiler() - Use spawnSync instead of execSync for PATH check 2. runCompiler() - Use spawnSync with arguments array instead of string concatenation Security improvements: - Use spawnSync instead of execSync (no shell spawning) - Pass arguments as array to prevent injection - Explicit shell: false option - Added security documentation in JSDoc Prevents command injection through PATH manipulation or file path injection. Follows OWASP secure coding practices. * docs: Add security fixes documentation Comprehensive documentation of command injection vulnerabilities fixed: - Detailed analysis of both security hotspots - Before/after code comparisons - Attack vector explanations - Risk assessment (High → Low) - Verification and testing - OWASP references and best practices Documents commit f7731b5 security improvements. * security(vscode): Enhance security by replacing execSync with spawnSync to prevent command injection vulnerabilities * security(vscode): Add compiler path configuration for PATH security hardening Addresses residual PATH security concern by adding user configuration option. Changes: 1. Added ferrisscript.compilerPath setting in package.json - Allows users to specify absolute path to trusted compiler - Bypasses PATH entirely when configured - Recommended for security-sensitive environments 2. Updated findCompiler() to check configuration first - Priority 1: User-configured absolute path (most secure) - Priority 2: Workspace target directories - Priority 3: PATH search (with timeout protection) 3. Enhanced security documentation - Explains residual PATH risk - Recommends absolute path configuration - Documents defense-in-depth approach Security Posture: - Low residual risk with PATH (mitigated by spawnSync + timeout) - Zero risk when absolute path configured - Standard practice for CLI tool discovery (npm, cargo, python) - User transparency via notifications Security scanners may still flag PATH usage as informational/low priority. This is acceptable for CLI tool discovery patterns. * docs: Add PATH security hardening analysis and guidance Comprehensive documentation for residual PATH security scanner finding. Covers: - Why PATH is flagged (even with spawnSync) - Defense-in-depth approach (config → workspace → PATH) - Risk assessment (Low → Negligible) - Comparison with industry tools (Python, Rust Analyzer) - User guidance for maximum security - Scanner response and compliance recommendations Provides justification for accepting low residual risk and proper documentation for security audits. * docs: Update PATH security hardening and residual risk mitigation guidance * feat(tooling): Phase 6+7 - Development Tooling & CI Benchmarking (#39) * feat(tooling): Phase 6+7 - Development tooling & CI benchmarking Phase 6: Development Scripts - Created scripts/lint.ps1 and lint.sh for cargo clippy linting - Implemented pre-commit hooks (format, lint, quick tests) - Updated install-git-hooks scripts to install pre-commit hook - Added comprehensive lint and hooks documentation to scripts/README.md Phase 7: Benchmark CI Integration - Created .github/workflows/benchmarks.yml for CI benchmark tracking - Workflow runs on main/develop branches - Stores results as artifacts (30-day retention) - Automatic PR comments with benchmark results - Verified all existing benchmarks run successfully Phase 9 Quick Wins: - Added Build Status badge to README.md Infrastructure: - All 263 tests passing - Zero clippy warnings - Code formatted - Documentation linted Deliverables: - 5/5 core scripts complete (test, bench, format, coverage, lint) - Pre-commit hooks installed and functional - CI benchmark tracking enabled - Professional project presentation with badges Closes #TBD (Phase 6+7 combined) * fix(ci): update Rust toolchain version and add components for linting fix(docs): update markdownlint action to latest version * docs: add test case and matrix for Phase 4 completion evaluation * feat(tooling): Add Git hooks uninstall scripts - Add scripts/uninstall-git-hooks.ps1 for Windows - Add scripts/uninstall-git-hooks.sh for Linux/macOS - Update scripts/README.md with uninstall documentation - Update Quick Reference table with new scripts - Add manual removal alternatives - Tested: Successfully removes pre-commit and pre-push hooks Benefits: - Easy hook removal for debugging or preference - Consistent with install script UX - Safe to run multiple times - Clear feedback on what was removed * fix(tooling): Ignore extensions directory in pre-push markdown linting * infra: Consolidate code scanning & coverage, evaluate CodeQL (#40) * infra: Consolidate code scanning and coverage reporting - Move Codecov from ci.yml to code-scanning.yml for consolidation - Disable SonarQube coverage (keep quality scanning, avoid redundancy) - Create docs/infrastructure/ folder for CI/CD documentation - Move COVERAGE_SETUP_NOTES.md to infrastructure folder - Add comprehensive infrastructure documentation: - README.md: Overview of all workflows, secrets, quality gates - CODEQL_EVALUATION.md: CodeQL integration analysis (2-4h effort, medium value) - Update workflow documentation (README.md, DEVELOPMENT.md) - Update coverage references to new infrastructure folder Rationale: - Groups security/quality tools (SonarQube, Codecov) in one workflow - Separates build/test (ci.yml) from analysis (code-scanning.yml) - Easier to add future tools (CodeQL) without cluttering ci.yml - Better organization: infrastructure docs in dedicated folder CodeQL Decision: - Do NOT implement for v0.0.3-0.0.4 (current tools sufficient) - Re-evaluate for v0.1.0+ (when Rust support matures) - Documented 2-4 hour integration effort with moderate value - See CODEQL_EVALUATION.md for full analysis Changes: - .github/workflows/ci.yml: Remove coverage job, add redirect comment - .github/workflows/code-scanning.yml: Add Codecov job, rename workflow - .github/workflows/README.md: Document consolidation - docs/DEVELOPMENT.md: Update coverage doc link - docs/infrastructure/: New folder with 3 comprehensive docs * security: Pin codecov-action to SHA for supply chain security - Pin codecov/codecov-action to SHA e28ff129e5465c2c0dcc6f003fc735cb6ae0c673 (v4.6.0) - Pin actions/checkout to SHA 11bd71901bbe5b1630ceea73d27597364c9af683 (v4.2.2) - Keep dtolnay/rust-toolchain@stable (no SHA pinning for toolchain updates) Rationale: - SHA pinning prevents supply chain attacks via compromised actions - Codecov v4.6.0 is latest stable with security improvements - Matches security pattern used in other workflows (ci.yml, sonarqube job) - Ensures reproducible builds and audit trail * fix(ci): Pin Rust toolchain version for consistency across workflows * fix(ci): add rustup target installation before cross-platform builds - Add 'rustup target add' step before building with --target flag - Fixes error: can't find crate for std when building for non-native targets - Error only appeared in CI after pushing to develop Prevents build failures when CI builds for Linux/macOS/Windows targets by ensuring the standard library for each target is installed before compilation.

* feat: v0.0.3 infrastructure - branching workflow and CI optimization (#22) * feat: implement v0.0.3 branching workflow and CI optimization - Create develop branch for integration testing - Add quick-check CI for feature branches (2-3 min) - Add path filters to skip CI for docs-only changes - Update CONTRIBUTING.md with new workflow documentation - Update PR templates to reference develop as base branch - Prepare for branch protection setup on main/develop Benefits: - 60-70% CI time savings on feature branches - 95% savings on docs-only PRs - Integration testing before production release - Clearer development workflow Refs: docs/planning/v0.0.3-roadmap.md (Development Workflow) Refs: docs/archive/v0.0.2/V0.0.2_DEFERRAL_ANALYSIS.md (CI optimization) * fix: replace approximate PI value with non-constant float in test Changed test value from 3.14 to 3.5 to avoid clippy::approx_constant warning. The test is verifying float value coercion, not mathematical constants. * docs: move comprehensive testing guide for v0.0.2 * chore: improve CI behavior documentation for branch workflows * feat: rename code scanning workflow with SonarQube integration * fix: resolve all clippy lint warnings in tests - Replace 3.14 with 3.5 in lexer test (avoids approx_constant lint) - Replace assert_eq! with assert! for boolean comparisons in parser tests - Remove assert!(true) placeholder in godot_bind tests (replace with comment) * fix(ci): pin Rust toolchain version for consistency * fix: prevent duplicate CI runs and improve clippy documentation - Remove feature/** from push triggers to prevent duplicate runs when PR exists - Simplify quick-check condition to only run on pull_request events - Update CONTRIBUTING.md to use full clippy command (--all-targets --all-features) - Fix rust-toolchain action configuration in quick-check job This resolves the issue where pushing to a feature branch with an open PR would trigger both push and pull_request events, running CI twice. * fix(docs): update relative links in TESTING.md for accuracy * fix: exclude docs/archive folder from markdown link checking Archive documentation may contain outdated or moved links that don't need to be validated in CI. This change adds a step to find markdown files while excluding the archive folder, target directory, and node_modules. Also excludes target/ and node_modules/ to avoid checking build artifacts. * fix: properly exclude all archive subdirectories from link checking The previous pattern './docs/archive/*' only matched files directly in the archive folder, not in subdirectories like 'docs/archive/v0.0.2/phases/'. Changed to '*/docs/archive/*' to match any path containing docs/archive, which properly excludes all 43 markdown files in the archive directory tree. This resolves the Status: 400 errors from archived documentation with relative links that no longer resolve correctly. * fix: run markdown-link-check directly with explicit file filtering The github-action-markdown-link-check action was running its own find command that ignored our filtered file list, causing it to check archive files despite our exclusion logic. Changed approach: - Install markdown-link-check directly via npm - Run find with explicit archive exclusion in the command - Remove dependency on third-party action for better control This ensures archive files are truly excluded from link checking. * docs: update workflows README for v0.0.3 infrastructure changes Comprehensive update to reflect all CI optimizations: New Features Documented: - Quick Check job (2-3 min fast PR feedback) - Path filters for docs-only changes (95% savings) - Three-branch workflow (main/develop/feature) - Archive exclusion in link checking Updated Sections: - Available Workflows: Added quick-check, updated all triggers - Job Details: Complete rewrite with v0.0.3 conditions - Performance Metrics: New timing table with 70% savings analysis - Event Flow Examples: 5 new examples covering all scenarios - Troubleshooting: Added v0.0.3-specific issues Benefits Highlighted: - 60-70% faster PR feedback (2-3 min vs 10-15 min) - 95% savings on docs PRs (CI skipped entirely) - 70% overall CI cost reduction - Prevented duplicate runs on feature branches All documentation now matches actual ci.yml and docs-lint.yml behavior. * feat(errors): implement comprehensive error code system (E001-E418) (#27) * feat(errors): implement comprehensive error code system (E001-E418) Phase 1 of v0.0.3 - Error Code System - Add ErrorCode enum with 55 variants across 5 categories: * Lexical errors (E001-E003) * Syntax errors (E100-E113) * Type errors (E200-E219) * Runtime errors (E400-E418) * Internal errors (E900-E999) - Implement error code formatting infrastructure - Update all compiler errors with structured codes: * Lexer: 6 errors → E001-E003 * Parser: 14 errors → E100-E113 * Type Checker: 19 errors → E200-E219 * Runtime: 24 errors → E400-E418 - Create comprehensive ERROR_CODES.md documentation (63 codes) - Add 9 error code validation tests - Fix documentation links in planning documents All 222 tests passing.

Simplify README.md (280 → 100 lines): Keep purpose, when to use, quick start - Simplify PR_TEMPLATE_SYSTEM.md (308 → 80 lines): Reference card only - Delete QUICK_REFERENCE.md (230 lines): Fully redundant with main prompt - Net result: -69% supplementary docs, +4% main prompt (1,066 lines) Incorporate deferred work into version roadmaps: - v0.0.4: Prompt testing, link checking automation (high priority) - v0.0.5: Pre-flight script, LEARNINGS generator, LSP quick fixes - v0.1.0+: Phase-specific prompts, telemetry, localization Addresses feedback from Phase 3C execution: - Dates often incorrect (defaulting to January) - TODO list updates inconsistent - Version-specific references in generic template - LEARNINGS.md updates not emphasized enough - Link checking coverage unclear - Deferred work recommendations integrated into roadmaps - Fragmented documentation across multiple files (consolidated) * fix: clean up formatting and improve clarity in documentation files * docs: move Prompts Folder Consolidation Analysis for improved Copilot usability * docs: Add type promotion research and post-v0.1.0 roadmaps - Created TYPE_PROMOTION_RESEARCH.md with comprehensive analysis: - Analyzed 6 game engines (Godot, Unity, Unreal, Bevy, Lua, JavaScript) - Compared 4 type promotion strategies - Documented performance implications and FFI considerations - Confirmed current i32/f32 approach is correct and Godot-compatible - Updated academic paper references with actual links - Created v0.2.0-roadmap.md (PROPOSED): - Extended type system (i64, f64, i16, u8, u16) -

Create PROMPT_OPTIMIZATION_RESEARCH.md analyzing GitHub Copilot premium request optimization - Key insight: Optimize for requests per feature, not tokens per request - Analyze 8 optimization strategies with impact ratings and estimated savings - High-impact strategies: clarification minimization, plan+execute fusion, deterministic completion - Medium-impact strategies: self-validation loop, error recovery, context pre-loading - Expected outcome: Reduce from 2-4 requests per feature to 1-1.5 requests (50-75% savings) - Provide 3-phase implementation roadmap (high-impact → risk mitigation → polish) - Define success metrics: quantitative (requests per feature) and qualitative (user experience) Also fix markdown linting issues in MARKDOWN_SYNTAX_HIGHLIGHTING_RESEARCH.md: - Convert emphasized text to proper headings (MD036) - Option A and Option B are now proper level 4 headings * feat(prompts): Implement Groups 1-2 of premium request optimizations Group 1: Foundation + High-Impact Core - Add Ambiguity Resolution Strategy section - Self-resolve low-risk ambiguities with documented assumptions - Only ask for high-risk decisions (API changes, security, data loss) - Expected savings: 1 request per feature (50% reduction) - Add Definition of Done section - Explicit completion checklist (code, docs, validation, output) - Clear DO NOT/ALWAYS lists for completion behavior - Required completion marker: '✅ Workstream Execution Complete' - Expected savings: 0.5-1 request per feature - Enhance Context Pre-Loading section - Full FerrisScript project identity and structure - Code and documentation conventions - Branch naming, commit format, quality standards - Test commands and CI/CD pipeline details - Version discovery (removed hardcoded versions, use docs/planning/) - Expected savings: 0.25-0.5 request per feature Group 2: Execution Flow Changes - Update Execution Planning section - Default: Brief plan (≤5 bullets) + immediate execution - No approval required for clear requirements - Fallback to explicit planning only if genuinely unclear - Expected savings: 1 request per feature (50% reduction) - Add Forward Progress Mandate section - Always make forward progress unless critically ambiguous - Make reasonable inferences, document assumptions - Only stop for high-risk ambiguities - Example scenarios with old vs new behavior - Expected savings: 0.5 request per feature - Add Self-Correction + Validation Loop section - 4-phase validation: syntax, tests, quality, links - Full license to fix code issues (no attempt limits) - Only stop when: validation passes, exhausted reasonable fixes, or tool is broken - Tool failure limit: 3 crashes (tool itself broken, not code) - Expected savings: 0.5-1 request per feature Total Expected Impact: Reduce from 2-4 requests/feature to 1-1.5 requests/feature (50-75% savings) Fixes based on review: - Remove hardcoded version numbers (v0.0.3, v0.1.0), use dynamic discovery from docs/planning/ - Clarify validation retry logic: unlimited code fix attempts, only limit tool crashes * feat(prompts): Implement Group 3 - Polish and Optional Features Group 3a: Hierarchical Output Structure (Strategy 5) - Add 'Required Output Structure' section with 7 standardized sections - Section 1: Executive Summary (goal, context, approach, assumptions) - Section 2: Implementation (files created/modified, key changes, code highlights) - Section 3: Documentation (created/updated, link validation results) - Section 4: Testing (tests added, execution results, coverage impact) - Section 5: Validation (build status, linting status, acceptance criteria) - Section 6: Post-Execution Notes (decisions, assumptions, recommendations, limitations) - Section 7: Completion Marker (deliverables summary, validation status, next action) - Benefits: Easy to scan, no ambiguity, evidence provided, reduces follow-up questions - Expected savings: 0.25 request per feature Group 3b: Execution Mode Toggle (Strategy 6) - Add 'Execution Modes' section with 3 modes: full, plan, execute - Mode 'full' (default): Plan + Execute + Document + Test in one pass - Mode 'plan': Only create execution plan, no implementation (exploratory) - Mode 'execute': Skip planning, proceed directly to implementation - Mode detection: Auto-detect from user language or explicit mode parameter - Usage: /prompt #file:workstream-execution.prompt.md mode=[mode] - Benefits: Flexibility for different scenarios, control over premium request usage - Expected savings: 0 (flexibility feature, not optimization) Total Group 3 Impact: +0.25 requests savings + improved UX clarity Note: Both sections in same file, staged together. Hierarchical Output Structure is higher priority (improves clarity), Execution Mode Toggle is optional (adds flexibility). All 8 optimization strategies now implemented: ✅ Strategy 1: Clarification Minimization (HIGH - Group 1) ✅ Strategy 2: Plan + Execute Fusion (HIGH - Group 2) ✅ Strategy 3: Deterministic Completion (MEDIUM-HIGH - Group 1) ✅ Strategy 4: Self-Correction + Validation (MEDIUM - Group 2) ✅ Strategy 5: Hierarchical Output Structure (LOW-MEDIUM - Group 3) ✅ Strategy 6: Execution Mode Toggle (LOW - Group 3) ✅ Strategy 7: Error Recovery Directive (MEDIUM - Group 2) ✅ Strategy 8: Context Pre-Loading (MEDIUM-HIGH - Group 1) Total Expected Impact: 50-75% reduction in premium requests (from 2-4 to 1-1.5 per feature) * fix(prompts): Clarify version planning discovery logic Clarify that active roadmap is the LOWEST version number, not highest: - Roadmaps are built outwards (plan future while working on earliest version) - Example: v0.2.0, v0.3.0, v0.4.0 exist → active work is v0.2.0 (lowest = current) - Higher-numbered roadmaps are forward planning, not current work - Add explicit 'Why lowest' explanation to prevent misinterpretation This ensures Copilot correctly identifies the current active version when multiple roadmaps exist in docs/planning/. * feat(vscode): Phase 4 - Code Completion Provider (v0.0.3) (#37) * feat(vscode): Add code completion provider for FerrisScript (Phase 4) Implement context-aware completion for keywords, types, and functions in VS Code extension. Features: - Keyword completion: let, mut, fn, if, else, while, return, true, false - Type completion: i32, f32, bool, String, Vector2, Node, void - Function completion: print with parameter hints - Context-aware suggestions: - Type position (after ':') shows only types - Statement start shows statement-level keywords - Expression context shows all keywords + functions - Snippet support for structured code insertion Technical Implementation: - TypeScript-based extension infrastructure (tsconfig, npm scripts) - CompletionItemProvider using VS Code API - Regex-based context detection - Comprehensive documentation with examples - Manual testing guide for validation Documentation: - PHASE_4_VS_CODE_COMPLETION.md: Full implementation plan - PHASE_4_MANUAL_TESTING.md: Testing guide with 10 test scenarios - Extension README and CHANGELOG updated - v0.0.3 roadmap documents aligned - LEARNINGS.md updated with Phase 4 insights References: - Phase 4 Document: docs/planning/v0.0.3/PHASE_4_VS_CODE_COMPLETION.md - Testing Guide: docs/planning/v0.0.3/PHASE_4_MANUAL_TESTING.md - Roadmap: docs/planning/v0.0.3/README.md - v0.0.3 Roadmap: docs/planning/v0.0.3/v0.0.3-roadmap.md Phase: 4 of 9 in v0.0.3 (Editor Experience Alpha) Status: Complete - Ready for manual testing and PR * style(docs): Fix markdown linting in Phase 4 documentation * fix(vscode): Address Phase 4 feedback - version, linting, docs Fixes: - Update extension version to 0.0.3 (aligns with completed work) - Remove redundant activationEvents (VS Code auto-generates from contributes) - Create extensions/vscode/.gitignore (exclude node_modules, out/, *.vsix) - Exclude extensions/vscode/node_modules from markdown linting Documentation: - Add TYPE_SYNC.md: comprehensive type synchronization guide - Documents manual sync requirements - Proposes validation scripts (v0.0.4) - Proposes type generation automation (v0.1.0+) - Plans LSP-based dynamic types (v0.0.5) - Update v0.0.3-roadmap.md: add Post-v0.0.3 Recommendations section - Type synchronization timeline - Build automation (local dev, CI/CD, release) - VSIX distribution strategy - Update README.md: - Add VSIX installation instructions - Add type completion maintenance section - Document extension activation behavior - Add architecture notes - Update CHANGELOG.md: promote v0.0.3 Phase 4 to released Rationale: - TypeScript compilation working (error was VS Code cache issue) - activationEvents removed per VS Code best practices (1.75+) - node_modules properly excluded from git and linting - Comprehensive documentation for future type synchronization - Clear roadmap for build automation and VSIX distribution * docs(prompt): Add Phase 4 learnings and GitHub CLI best practices GitHub CLI Documentation: - Create GITHUB_CLI_PR_CREATION.md with 3 solutions for backtick escaping - Recommend --body-file approach as standard (avoids shell interpretation) - Document PowerShell/Bash differences and workarounds - Include PR template examples and automation helpers - Provide lessons learned from Phase 4 PR creation issue Prompt Improvements Documentation: - Create PROMPT_IMPROVEMENTS_PHASE4.md analyzing Phase 4 execution - Document 6 issues that needed correction: 1. GitHub CLI backtick escaping (PR corruption) 2. Version misalignment (0.1.0 vs 0.0.3) 3. Missing .gitignore (node_modules tracked/linted) 4. Redundant activationEvents (deprecated VS Code practice) 5. TypeScript error communication gap (cache issue) 6. Reactive documentation (type sync, build automation, VSIX) - Provide 7 prompt improvement recommendations: 1. GitHub CLI best practices (--body-file) 2. Version alignment verification 3. Standard project files checklist 4. Proactive maintenance documentation 5. VS Code extension best practices (2024+) 6. Discrepancy investigation protocol 7. Automation decision framework - Define success metrics and validation approach Rationale: - Phase 4 revealed patterns where Copilot was reactive vs proactive - Backtick issue was most visible problem (corrupted PR description) - Documentation improvements prevent repeat issues in future phases - Framework helps decide when to automate vs document vs roadmap Impact: - Future phases should anticipate maintenance needs proactively - PR creation will use reliable --body-file approach - Standard files (.gitignore, package.json) created upfront - Version context verified before setting versions References: - Phase 4 execution: 3 commits, 6 feedback items, 1 PR failure - Phase 5 target: 2 commits, ≤2 feedback items, 0 failures - Phase 6+ goal: 1 commit, 0 corrections, 100% smooth * exclude markdownlint rule M037 * docs: Apply Phase 4 prompt improvements Implement 7 prompt improvements identified during Phase 4 execution to keep them contextually close to when the work was done.

Incorrect .vscodeignore configuration - Removed: out/ from ignore (needed for compiled JS) - Added: src/, tsconfig.json, .eslintrc.json (source files) - Fixed: Now ships compiled JS, not TypeScript source 3. Missing icon.png - Copied: assets/ferrisscript-logo.png → extensions/vscode/icon.png - Extension marketplace icon now present 4. Missing LICENSE - Copied: LICENSE → extensions/vscode/LICENSE - Satisfies vsce package requirements Result: Successfully packaged as ferrisscript-0.0.3.vsix (48 files, 879.95KB) Installation: Extension installed via 'code --install-extension ferrisscript-0.0.3.vsix' This should resolve the icon theme caching issue - fresh VSIX package = fresh install. * fix(vscode): Remove icon theme - fundamental misunderstanding of VS Code icon system Issue: Icon theme replaced ALL file icons, not just .ferris files Root Cause: Icon themes are COMPLETE icon sets (like Seti, Material Icons) - Must define icons for hundreds of file types - Cannot add single file icon without defining all others - When selected, replaces ALL file icons in VS Code Resolution: Removed iconThemes contribution from package.json - Removed: contributes.iconThemes section - Kept: All other features (hover, completion, diagnostics) - Updated: CHANGELOG.md to remove file icon mention - Updated: PHASE_5_MANUAL_TESTING.md Test 13 status Why This Is Correct: 1. Language extensions (Rust, Python, Julia) don't ship icon themes 2. File icons are managed by dedicated icon theme extensions 3. Icon themes require defining icons for ALL file types 4. Not feasible for single-language extension Impact: - .ferris files will use default file icon from active icon theme - All other extension features (hover, completion, diagnostics) unaffected - Extension now follows VS Code best practices Testing: Packaged and installed - 'FerrisScript Icons' no longer appears in icon theme list Acceptance Criteria Update: 7/10 met (removed infeasible criterion) * docs: Add icon theme lesson learned to LEARNINGS.md Documented complete analysis of icon theme misunderstanding: - Why icon themes are complete replacements, not augmentations - Technical details of VS Code icon system architecture - Why we can't use icon themes for single file type - How other language extensions handle this (they don't ship icon themes) - Alternative approach: Submit PRs to popular icon theme extensions - Recommendations for future development Key Takeaway: Icon themes must define ALL file types. Language extensions should focus on core features (hover, completion, diagnostics) and leave icons to dedicated icon theme extensions. * docs: Add Phase 5 PR description and summary Comprehensive PR documentation including: - Feature overview (hover tooltips, diagnostic infrastructure) - Testing results (9/15 passing, 5 N/A, 1 removed) - Issues resolved (icon theme, VSIX packaging, CLI limitation) - Documentation created (6 new files, 4 updated) - Deferred work (CLI implementation, LSP server) - Acceptance criteria status (7/10 met) - Deployment instructions and verification checklist Ready to create PR: feature/v0.0.3-phase-5-hover → develop * docs: Add Phase 5 completion summary Final summary document including: - All accomplishments and deliverables - Testing results and acceptance criteria - Key lessons learned (icon theme, VSIX, CLI) - Statistics (23 files, +2,935 lines) - Deferred work and priorities - PR details (#38) - Success metrics and next steps Phase 5 complete: Hover tooltips working, diagnostic infrastructure ready, extension packaging working, comprehensive documentation created. * docs: Update Phase 5 documentation and testing guides to reflect icon theme removal and fixes * security(vscode): Fix command injection vulnerabilities in diagnostic provider Fixed 2 security hotspots: 1. findCompiler() - Use spawnSync instead of execSync for PATH check 2. runCompiler() - Use spawnSync with arguments array instead of string concatenation Security improvements: - Use spawnSync instead of execSync (no shell spawning) - Pass arguments as array to prevent injection - Explicit shell: false option - Added security documentation in JSDoc Prevents command injection through PATH manipulation or file path injection. Follows OWASP secure coding practices. * docs: Add security fixes documentation Comprehensive documentation of command injection vulnerabilities fixed: - Detailed analysis of both security hotspots - Before/after code comparisons - Attack vector explanations - Risk assessment (High → Low) - Verification and testing - OWASP references and best practices Documents commit f7731b5 security improvements. * security(vscode): Enhance security by replacing execSync with spawnSync to prevent command injection vulnerabilities * security(vscode): Add compiler path configuration for PATH security hardening Addresses residual PATH security concern by adding user configuration option. Changes: 1. Added ferrisscript.compilerPath setting in package.json - Allows users to specify absolute path to trusted compiler - Bypasses PATH entirely when configured - Recommended for security-sensitive environments 2. Updated findCompiler() to check configuration first - Priority 1: User-configured absolute path (most secure) - Priority 2: Workspace target directories - Priority 3: PATH search (with timeout protection) 3. Enhanced security documentation - Explains residual PATH risk - Recommends absolute path configuration - Documents defense-in-depth approach Security Posture: - Low residual risk with PATH (mitigated by spawnSync + timeout) - Zero risk when absolute path configured - Standard practice for CLI tool discovery (npm, cargo, python) - User transparency via notifications Security scanners may still flag PATH usage as informational/low priority. This is acceptable for CLI tool discovery patterns. * docs: Add PATH security hardening analysis and guidance Comprehensive documentation for residual PATH security scanner finding. Covers: - Why PATH is flagged (even with spawnSync) - Defense-in-depth approach (config → workspace → PATH) - Risk assessment (Low → Negligible) - Comparison with industry tools (Python, Rust Analyzer) - User guidance for maximum security - Scanner response and compliance recommendations Provides justification for accepting low residual risk and proper documentation for security audits. * docs: Update PATH security hardening and residual risk mitigation guidance * feat(tooling): Phase 6+7 - Development Tooling & CI Benchmarking (#39) * feat(tooling): Phase 6+7 - Development tooling & CI benchmarking Phase 6: Development Scripts - Created scripts/lint.ps1 and lint.sh for cargo clippy linting - Implemented pre-commit hooks (format, lint, quick tests) - Updated install-git-hooks scripts to install pre-commit hook - Added comprehensive lint and hooks documentation to scripts/README.md Phase 7: Benchmark CI Integration - Created .github/workflows/benchmarks.yml for CI benchmark tracking - Workflow runs on main/develop branches - Stores results as artifacts (30-day retention) - Automatic PR comments with benchmark results - Verified all existing benchmarks run successfully Phase 9 Quick Wins: - Added Build Status badge to README.md Infrastructure: - All 263 tests passing - Zero clippy warnings - Code formatted - Documentation linted Deliverables: - 5/5 core scripts complete (test, bench, format, coverage, lint) - Pre-commit hooks installed and functional - CI benchmark tracking enabled - Professional project presentation with badges Closes #TBD (Phase 6+7 combined) * fix(ci): update Rust toolchain version and add components for linting fix(docs): update markdownlint action to latest version * docs: add test case and matrix for Phase 4 completion evaluation * feat(tooling): Add Git hooks uninstall scripts - Add scripts/uninstall-git-hooks.ps1 for Windows - Add scripts/uninstall-git-hooks.sh for Linux/macOS - Update scripts/README.md with uninstall documentation - Update Quick Reference table with new scripts - Add manual removal alternatives - Tested: Successfully removes pre-commit and pre-push hooks Benefits: - Easy hook removal for debugging or preference - Consistent with install script UX - Safe to run multiple times - Clear feedback on what was removed * fix(tooling): Ignore extensions directory in pre-push markdown linting * infra: Consolidate code scanning & coverage, evaluate CodeQL (#40) * infra: Consolidate code scanning and coverage reporting - Move Codecov from ci.yml to code-scanning.yml for consolidation - Disable SonarQube coverage (keep quality scanning, avoid redundancy) - Create docs/infrastructure/ folder for CI/CD documentation - Move COVERAGE_SETUP_NOTES.md to infrastructure folder - Add comprehensive infrastructure documentation: - README.md: Overview of all workflows, secrets, quality gates - CODEQL_EVALUATION.md: CodeQL integration analysis (2-4h effort, medium value) - Update workflow documentation (README.md, DEVELOPMENT.md) - Update coverage references to new infrastructure folder Rationale: - Groups security/quality tools (SonarQube, Codecov) in one workflow - Separates build/test (ci.yml) from analysis (code-scanning.yml) - Easier to add future tools (CodeQL) without cluttering ci.yml - Better organization: infrastructure docs in dedicated folder CodeQL Decision: - Do NOT implement for v0.0.3-0.0.4 (current tools sufficient) - Re-evaluate for v0.1.0+ (when Rust support matures) - Documented 2-4 hour integration effort with moderate value - See CODEQL_EVALUATION.md for full analysis Changes: - .github/workflows/ci.yml: Remove coverage job, add redirect comment - .github/workflows/code-scanning.yml: Add Codecov job, rename workflow - .github/workflows/README.md: Document consolidation - docs/DEVELOPMENT.md: Update coverage doc link - docs/infrastructure/: New folder with 3 comprehensive docs * security: Pin codecov-action to SHA for supply chain security - Pin codecov/codecov-action to SHA e28ff129e5465c2c0dcc6f003fc735cb6ae0c673 (v4.6.0) - Pin actions/checkout to SHA 11bd71901bbe5b1630ceea73d27597364c9af683 (v4.2.2) - Keep dtolnay/rust-toolchain@stable (no SHA pinning for toolchain updates) Rationale: - SHA pinning prevents supply chain attacks via compromised actions - Codecov v4.6.0 is latest stable with security improvements - Matches security pattern used in other workflows (ci.yml, sonarqube job) - Ensures reproducible builds and audit trail * fix(ci): Pin Rust toolchain version for consistency across workflows * fix(ci): add rustup target installation before cross-platform builds - Add 'rustup target add' step before building with --target flag - Fixes error: can't find crate for std when building for non-native targets - Error only appeared in CI after pushing to develop Prevents build failures when CI builds for Linux/macOS/Windows targets by ensuring the standard library for each target is installed before compilation.
