Reviewer's GuideThis PR standardises British spelling by replacing all instances of “behavior” with “behaviour” (and their variants) across the project’s Markdown documentation, and reapplies formatting via mdformat, markdownlint, and related tools to ensure consistent style. File-Level Changes

WalkthroughThis update removes all numeric citation markers from the complexity antipatterns document and standardises the spelling of "behaviour" to British English across three documentation files. Minor editorial refinements and removal of extraneous numeric footnotes were also applied in several other docs. No content, logic, or technical explanations were altered; only orthography and citation formatting were changed. Changes

Learning: Cyclomatic Complexity (CC) is a metric that quantifies the number of linearly independent paths through a program's source code, primarily measuring testability and execution paths. High CC indicates more test cases are needed and increased maintenance risk. Thresholds: 1-10 (simple), 11-20 (moderate risk), 21-50 (high risk), >50 (untestable).

Learning: Cyclomatic Complexity (CC) is a metric that quantifies the number of linearly independent paths through a program's source code, primarily by counting decision points such as if statements and conditional loops. High CC indicates more intricate control flow, which increases the number of test cases required and impacts maintainability. Functions with CC above 20 generally require refactoring.

Learning: Cognitive Complexity is a metric that measures how difficult code is for a human to read and understand. It increases with breaks in linear flow (e.g., loops, conditionals, try-catch blocks), deeper nesting, and mixed logical operators. Method calls are generally 'free' unless recursive. High Cognitive Complexity slows development and increases maintenance costs.

Learning: The 'Bumpy Road' antipattern describes functions or methods with multiple deeply nested sections, each representing a distinct responsibility that should be encapsulated. It is characterized by visual 'hills and valleys' in indentation, lack of encapsulation, increased cognitive load, and feature entanglement. This antipattern is a strong predictor of code that is expensive to maintain and risky to evolve.

Learning: The 'Bumpy Road' antipattern describes functions or methods with multiple deeply nested sections of logic, resulting in a visually 'bumpy' indentation pattern. This structure increases cognitive load, reduces readability, and often signals a violation of the Single Responsibility Principle. Each 'bump' typically represents a missing abstraction.

Learning: Parameterized tests in rstest are created using #[case(...)] for table-driven scenarios and #[values(...)] for combinatorial testing.

Learning: rstest supports asynchronous tests and fixtures by allowing async fn for both. It integrates with async runtimes like async-std or tokio by stacking the appropriate test attribute (e.g., #[tokio::test]) with #[rstest]. The #[future] and #[awt] attributes simplify working with futures by removing boilerplate and optionally auto-awaiting arguments.

Learning: By default, rstest creates a new instance of each fixture for every test that uses it, ensuring test isolation and preventing shared mutable state between tests. The #[once] attribute can be used to share a static reference to a fixture across tests, but such fixtures are never dropped and should only be used for read-only, static data.

Learning: Red flags for emerging Bumpy Roads include rising Cognitive Complexity scores, deeply nested logic (more than 2-3 levels), functions that do 'too much', frequent unrelated modifications to the same function, difficulty in unit testing, long methods, and declining code health metrics.

Learning: Separation of Concerns (SoC) is a design principle advocating for dividing a program into distinct sections, each addressing a separate concern.

Learning: Command Query Responsibility Segregation (CQRS) is an architectural pattern that separates operations that modify state (commands) from those that read state (queries). Applying CQRS helps prevent Bumpy Roads by encouraging smaller, focused methods and handlers, and can guide refactoring of complex methods into distinct command/query handlers.

High CC indicates more intricate control flow, which increases the number of test cases required and impacts maintainability. Functions with CC above 20 generally require refactoring.

Learning: Cognitive Complexity measures how difficult code is for a human to read and understand, focusing on breaks in linear flow, nesting, and discounts for well-named abstractions. High Cognitive Complexity slows development and increases maintenance costs. Tools like SonarQube flag functions exceeding set thresholds.

Learning: The 'Bumpy Road' antipattern describes functions or methods with multiple deeply nested sections, each representing a distinct responsibility that should be encapsulated. It is characterized by visual 'hills and valleys' in indentation, lack of encapsulation, increased cognitive load, and feature entanglement. This antipattern is a strong predictor of code that is expensive to maintain and risky to evolve.

Learning: The 'Bumpy Road' antipattern describes functions or methods with multiple deeply nested sections of logic, resulting in a visually 'bumpy' indentation pattern. This structure increases cognitive load, reduces readability, and often signals a violation of the Single Responsibility Principle. Each 'bump' typically represents a missing abstraction.

Learning: Separation of Concerns (SoC) is a design principle advocating for dividing a program into distinct sections, each addressing a separate concern.

Learning: Command Query Responsibility Segregation (CQRS) is an architectural pattern that separates operations that modify state (commands) from those that read state (queries). Applying CQRS helps prevent Bumpy Roads by encouraging smaller, focused methods and handlers, and can guide refactoring of complex methods into distinct command/query handlers.

Learning: The design should ensure cancellation safety: dropping a FrameStream (e.g., due to shutdown or handler panic) should not leak resources or hang the connection, as StreamExt::next() is cancellation-safe and the connection actor will treat the stream as completed.

Learning: In Rust libraries for binary protocol handling, derive macros for (de)serialization traits (such as Encode/Decode or Serde's Deserialize/Serialize) are essential for reducing boilerplate and minimizing manual byte manipulation. Libraries like bincode, postcard, and bin-proto exemplify this pattern, and any framework aiming to reduce source code complexity should prioritize automated (de)serialization via derive macros.

🧹 Nitpick (assertive)
Capitalise the proper noun “Serde”.
Within Rust documentation the crate is normally referred to as “Serde”. Using the lowercase form can read as a common noun rather than the crate name.

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

In docs/rust-binary-router-library-design.md at lines 157 to 158, the word
"serde" should be capitalized to "Serde" to correctly refer to the Rust crate as
a proper noun. Update the text to use "Serde" instead of "serde" to align with
Rust documentation conventions.
