Key Changes

1. Project Configuration and Development Foundation

Established the initial project infrastructure and standardized its development configuration.

• Added the package manifest and npm scripts.

• Configured TypeScript compiler options, module resolution, strict type-checking flags, include/exclude paths, and declaration outputs.

• Added ESLint configuration with TypeScript ESLint parsing, recommended rules, custom constraints, and overrides.

• Configured Vitest with test discovery patterns, execution environment, V8 coverage reporting, and coverage exclusions.

• Added dependency lockfiles for the compiler, bundler, testing tools, and related packages.

• Updated .gitignore to exclude standard Node.js artifacts, build output, coverage data, VSIX packages, operating-system metadata, and transient ProofCode reports.

These changes provide a consistent baseline for development, static analysis, testing, and packaging.

2. Build System and Distribution Packaging

Introduced the esbuild-based build configuration and Visual Studio Code packaging rules.

Build configuration

• Initialized the esbuild build script and its options.

• Added a CLI executable target with a shebang banner.

• Implemented production minification.

• Added watch-mode build context support.

Packaging configuration

• Introduced .vscodeignore.

• Excluded development sources, tests, coverage artifacts, and unnecessary files from the VSIX package.

• Refined inclusion rules to target a minimal extension bundle.

The build and packaging configuration separates development resources from distributable extension assets.

3. Visual Studio Code Extension Setup

Established the extension manifest and editor-development workflow.

• Added extension metadata and npm scripts.

• Declared the Activity Bar container, views, and commands.

• Defined the extension configuration schema and CLI binary metadata.

• Configured launch.json for extension-host debugging.

• Added extension-host launch options and pre-launch configuration.

• Linked the demo application workspace for interactive F5 testing.

• Created the initial SVG shield icon and refined its geometry, emerald brand palette, viewBox, and theme compatibility.

This lays the groundwork for developing and interacting with ProofCode inside Visual Studio Code.

4. Architectural Rules and Engineering Policies

Introduced an initial architectural policy template and a Markdown-based rules foundation.

The documented policies cover:

• Authentication and authorization expectations.

• Data privacy and sensitive information handling.

• Resource ownership.

• Idempotency guidelines.

• Test requirements.

• Additional engineering constraints represented by the project rules configuration.

The implementation also introduces a ProjectRulesEngine and Markdown rules parser, with checks for authentication, sensitive-field leaks, resource ownership, testing requirements, and related policy violations.

These rules provide a foundation for evaluating code changes against explicit project-level expectations.

5. Shared Type Definitions and Analysis Models

Added TypeScript interfaces and models to support communication between analysis components.

The declared types cover:

• Git diff data.

• AST symbol extraction.

• Impact analysis.

• Function callers and relationships.

• Risk evidence traces.

• Verification reports.

• Verification scores.

• Breakage risk models.

These contracts establish consistent data structures for collecting analysis results, tracing evidence, calculating impact, and generating reports.

6. Git Integration and Diff Parsing

Introduced the Git service and diff parser required to inspect repository changes.

Git service

• Initialized the GitService class and shell execution helper.

• Implemented branch discovery.

• Added parsing for Git porcelain status output.

• Added synthetic diff generation for untracked files.

Diff parser

• Added file-header matching.

• Implemented hunk-header parsing.

• Added line-number tracking.

• Calculated exact modified line ranges.

• Added handling for renamed files.

Together, these components establish the Git change-discovery layer used by the broader analysis pipeline.

7. TypeScript AST Analysis

Introduced the ASTAnalyzer using the TypeScript Compiler API.

The analyzer work includes:

• Initialization of the AST analysis component.

• Inspection of symbols and declarations.

• Visibility into import and export declarations.

• Detection of endpoints in Next.js App Router and Pages Router structures.

This creates the source-analysis foundation for identifying relevant code constructs and connecting modified files to application-level behavior.

8. Project Dependency Graph and Change Impact Analysis

Introduced the ProjectGraph component for mapping project structure and relationships.

• Added file discovery and module resolution.

• Built reverse dependency mappings.

• Added function-call relationships.

• Implemented computeImpact.

• Added blast-radius analysis and associated test coverage.

The graph layer provides a way to reason about how a change in one part of a project may affect dependent modules and connected functions.

9. Security and Code Risk Detection

Introduced the RiskEngine, using an AST visitor and evidence-trace foundation to evaluate potential code risks.

Security-focused checks

• SQL injection detection.

• Missing authorization checks.

• Hardcoded secret detection.

• Server-Side Request Forgery (SSRF) detection.

• Authentication-related policy checks.

• Sensitive-field leak checks.

• Resource ownership and related rule enforcement.

Reliability-focused checks

• Unhandled null database-query results.

• Unhandled asynchronous operations, including the PC-REL-006 detector.

• Test-fixture filtering.

• Finding deduplication.

The risk engine also introduces the collection and representation of evidence associated with detected risks.

These capabilities establish the initial security and reliability analysis layer. The findings should be treated as automated detection results that require appropriate validation rather than as a guarantee that every vulnerability will be identified.

10. Verification and Test Execution

Added the TestRunner component and its command-execution helper.

The runner includes:

• Package-manager detection through lockfiles.

• Type-check execution.

• Lint execution.

• Test execution.

• Build execution.

This provides a unified execution layer for gathering verification results from the project's existing development tools.

11. ProofCode Engine Orchestration

Introduced the ProofCodeEngine to coordinate the analysis workflow.

The engine work includes:

• Initializing the engine and verification options.

• Orchestrating Git diff collection, AST parsing, and dependency-graph impact analysis.

• Implementing transparent score deductions.

• Adding verdict logic.

• Defining the BreakageRiskItem model and collection pipeline.

• Detecting downstream authentication and core-service breakage risks.

• Mapping rule violations and untested dependents into breakage-risk results.

This orchestration layer connects the individual analysis components into a coordinated change-verification pipeline.

12. Reporting and Result Serialization

Introduced the ReportFormatter for transforming analysis results into consumable output formats.

Markdown reporting

• Added tables.

• Included evidence traces.

• Structured analysis findings for readable reports.

Additional output formats

• Added terminal serialization through toTerminal.

• Added JSON serialization through toJson.

The formatter provides a common reporting layer for presenting findings across different development and automation environments.

13. VS Code Analysis Tree and Evidence Navigation

Introduced the ProofCodeTreeDataProvider and tree-item models.

The editor-facing functionality includes:

• Root category nodes.

• Evidence-jump commands.

• A What Could Break tree node.

• Dynamic refresh event handling.

These additions establish a navigable representation of analysis findings inside the VS Code interface, with commands for jumping to supporting evidence.

14. GitHub Actions Continuous Integration

Added the initial GitHub Actions CI workflow structure.

The workflow configuration includes:

• A Node.js version matrix.

• Test execution steps.

• Bundle verification.

• CLI validation.

• VSIX packaging checks.

This establishes an automated CI foundation for validating the project across configured Node.js versions and checking important build and distribution artifacts.
