Thank you for identifying and correcting the missing possessive pronoun. The change from not yet turn to not yet its turn is grammatically correct, preserves the intended meaning, and is made in the correct authoritative Kernel source.

Review outcome: Changes Requested — merge after the required governance write-back is completed.

Changing K13/10 changes the measured file size from 8,806 to 8,810 bytes and invalidates the source hashes of five dependent Cards. The current CI failure is therefore expected: the PR is missing the deterministic derived updates.

Please:

1. update the K13/10 measurement in K00/16 from 8806 to 8810;
2. regenerate/stamp R03, R06, R07, R10, and R11;
3. synchronize the branch with the current main; and
4. rerun the required checks.

After those write-back changes are included, this PR is suitable to merge. It is also the best integration PR for the related wording improvements in #71 and #73, because it already creates a legitimate K00/16 and R07 regeneration boundary.

For future contributions, please open an Issue first so that the problem, authority layer, and required derived artifacts can be agreed before implementation. Then open a linked PR using a reference such as Closes #<issue-number>. This keeps the governance trail and review scope clear.
