EIP Delta Builder

Purpose-built delta diff generator for Ethereum Improvement Proposals. It accepts a base EIP and a target EIP, computes line- and section-level changes, and exports a machine- and human-readable delta. The tool normalizes metadata, validates semver-like EIP identifiers, and produces both a delta JSON and a patch-style text. It is designed for developers, auditors, and governance teams who track protocol evolution and need reproducible change records.
Conceptually, inputs are parsed from a repository or provided content, then a diff engine compares structure, prose, and code blocks. Outputs include a structured delta object, a patch, and a summary suitable for PRs or release notes. The approach emphasizes determinism, reproducibility, and easy integration into CI, audit workflows, and archival processes.
Unique value lies in domain-aware normalization, filtering by sections (e.g., rationale, specs, tests), and export formats that align with EIP governance practices. Use cases include generating release diffs, validating proposed changes, and maintaining change history across versions. The tool avoids generic text diffs and focuses on EIP-specific fields, links, and metadata to reduce noise and improve traceability.
