**/*.rs: Comment why, not what. Explain assumptions, edge cases, trade-offs, or complexity. Don't echo the obvious.
Comments must use en-GB-oxendict spelling and grammar.
Function documentation must include clear examples.
Every module must begin with a module level (//!) comment explaining the module's purpose and utility.
Document public APIs using Rustdoc comments (///) so documentation can be generated with cargo doc.
Place function attributes after doc comments.
Do not use return in single-line functions.
Use predicate functions for conditional criteria with more than two branches.
Lints must not be silenced except as a last resort.
Lint rule suppressions must be tightly scoped and include a clear reason.
Prefer expect over allow.
Prefer .expect() over .unwrap().
Clippy warnings MUST be disallowed.
Fix any warnings emitted during tests in the code itself rather than silencing them.
Where a function is too long, extract meaningfully named helper functions adhering to separation of concerns and CQRS.
Where a function has too many parameters, group related parameters in meaningfully named structs.
Where a function is returning a large error consider using Arc to reduce the amount of data returned.
Write unit and behavioural tests for new functionality. Run both before and after making any change.
Prefer immutable data and avoid unnecessary mut bindings.
Handle errors with the Result type instead of panicking where feasible.
Avoid unsafe code unless absolutely necessary and document any usage clearly.

40-42: Excellent documentation improvement.

The expanded explanation clearly describes the edge case behaviour when max_high_before_low is zero, which aligns perfectly with the implementation in should_yield_to_low_priority(). This follows the coding guidelines by explaining the "why" behind the zero value behaviour rather than just the "what".
