I noticed a common AI writing pattern not yet covered: diff-anchored writing, where documentation or comments describe what changed rather than what is, making them unreadable without knowing the prior state.

This is distinct from version-scoped documents like release notes or changelogs, where referencing changes is expected.

Before:

This function was added to replace the previous approach of iterating through all items. The old method caused O(n²) performance, so we now use a hash map instead.

After:

This function uses a hash map for O(1) lookups per item, avoiding the O(n²) cost of naive iteration.

Before:

We removed the legacy_auth middleware because legal flagged it for storing session tokens in a non-compliant way. The new implementation uses encrypted cookies.

After:

Authentication uses encrypted cookies for session storage, meeting the current compliance requirements for token handling.

Happy to submit a PR if this fits the project's direction.
