Commit A makes project-wide source changes that improve code quality and maintainability: it fixes Clippy warnings across multiple modules, enables a missing test by adding a #[test] attribute, introduces a type alias to simplify a complex signature, modernizes idioms, and adjusts shared integration-test helpers. While mostly non-functional, these changes directly affect the build and test hygiene of the codebase. Commit B only adds two documentation/planning files containing notes and architectural ideas without changing the implementation. Those documents may be useful for future work, but they do not immediately improve or modify the software itself.

Side A makes concrete improvements to the codebase: fixing clippy warnings, tightening patterns, simplifying code, adding a missing test annotation, and improving minor APIs and tests across multiple modules. These changes improve correctness, maintainability, and build hygiene. Side B is extensive but consists only of notes and a design document, which don’t affect the running system. While useful for planning, it doesn’t contribute executable value yet.

Commit A improves the production codebase by fixing workspace-wide clippy warnings, tightening patterns, simplifying code, adding a missing test annotation, introducing a type alias for readability, and cleaning up multiple modules and tests. These changes enhance code quality, maintainability, and CI hygiene across many files. Commit B adds planning and notes documents with substantial text, but no executable code or functional changes. While useful for future direction, it does not directly impact the running system. Therefore, Commit A contributes significantly more to the project.

Commit B makes a functional improvement to the project by exposing graph connectivity statistics in CLI output, integrating the new information into user-visible responses, and adding unit tests for the formatting logic. Commit A only adds developer notes and a design document describing proposed architecture, without changing application behavior or implementation. While design documentation can be valuable, B delivers concrete, tested functionality and therefore contributes substantially more.

Side A adds informal notes and a large architectural write-up, but no executable changes or integrated functionality. Side B introduces a concrete CLI feature (connectivity stats display), integrates it into output, and includes tests. This directly improves user-facing behavior and code quality, making it a substantially more impactful contribution.

Side A adds planning notes and a large architectural design document, but no functional or executable changes to the codebase. Side B introduces a concrete CLI feature (connectivity statistics display), integrates it into output flow, and adds unit tests to verify behavior. This directly improves user-facing functionality and code quality, making Side B the more substantial contribution.

Side A makes project-affecting maintenance changes: it restores a missing `#[test]` so a UI action test runs, adds a targeted `#![allow(dead_code)]` for shared integration helpers, introduces a type alias to simplify a complex return type, and applies multiple Clippy-driven correctness and idiomatic fixes across server and types. Side B only adds planning documents and personal notes (`notes.tdsl` and `plan2.md`) without changing executable code or tests, so it provides little lasting implementation value.

Side A makes concrete code improvements: fixes tests (adding a missing #[test]), simplifies pattern matches, introduces a type alias for readability, and applies small correctness/idiomatic fixes (e.g., is_some_and, removing unnecessary borrows). Side B only adds a notes file and a design document with no executable impact on the codebase.

Side A makes concrete code improvements across the workspace: fixes clippy warnings (e.g., replacing match destructuring with direct let patterns), improves API usage (`is_some_and`, removing unnecessary borrows), adds a missing `#[test]`, introduces a type alias to simplify a complex return type, and allows dead code in shared test helpers to keep CI clean. Side B only adds informal notes and a planning document with no executable code or integration, providing no immediate impact on the codebase.

Side A makes real, verifiable code improvements: fixing a broken/dead test (adding #[test]), removing an unreachable match arm now flagged by clippy, adding a documented dead_code allowance for shared test helpers, and applying idiomatic clippy fixes across multiple files. Side B merely adds a personal notes file and a speculative AI-generated design essay (plan2.md) that contains no actual implemented code changes to the project.

A makes lasting code improvements: it enables a previously inert ui_action test with #[test], quiets real clippy issues, and tightens match/idiom usage across server and types. B only adds scratch notes.tdsl and an architectural plan2.md with no implemented behavior, so it does not change the product.

Side B adds functional CLI behavior by formatting and displaying connectivity statistics in pair responses, helping users understand graph density and disconnected components, and includes unit tests covering connected and sparse cases. Side A only adds a personal notes file and an architectural planning document without changing the project's executable behavior or implementation.

Side B adds a concrete CLI feature (`format_connectivity_stats`), integrates it into `print_pair_response`, and includes tests validating output, directly improving functionality. Side A only introduces a notes file and a large planning document with no executable impact on the codebase.

Side A only adds two new documentation/planning files (`notes.tdsl` and `plan2.md`) with prose and example code that are not integrated into the codebase. Side B adds a concrete CLI feature (`format_connectivity_stats`), wires it into `print_pair_response`, and includes unit tests, delivering real user-visible functionality with verification.

Side B adds actual working, tested code that surfaces graph connectivity stats in the CLI, providing real user-facing value and test coverage. Side A is just a notes/scratchpad file and an AI-generated speculative architecture writeup with no code integrated into the project, offering no lasting functional value.

B ships a real CLI feature (format_connectivity_stats + wiring into pair output) with focused unit tests that surface existing graph stats to users. A only adds scratch TODO notes and an architecture brainstorm markdown file with no executable product change.
