Title Check	✅ Passed	The PR title "docs: improve grammar in blog/elysia-04.md" is partially related to the changeset. The raw summary confirms that grammar and style tweaks are genuine components of the changes made to the blog post. However, the summary indicates the changes are broader than just grammar—they include prose refinements, terminology clarifications, technical explanation improvements, and editorial updates for overall clarity. The title refers to a real aspect of the change (grammar improvements) but represents a narrower scope than the actual editorial and clarity-focused work performed across the file.
Docstring Coverage	✅ Passed	No functions found in the changes. Docstring coverage check skipped.

41-43: Opening prose is clearer and more engaging.

The refined opening accurately frames this release as foundational work rather than a marquee feature, setting appropriate expectations for readers.

---

45-58: Technical explanations are more precise and coherent.

The section now clearly explains the performance rationale behind Ahead-of-Time Compilation, with more accurate terminology (e.g., "small runtime overhead" vs. "minimal") and a better flow from problem identification to solution. The header is also corrected to "Ahead-of-Time Compile."

---

61-61: Tense and terminology are now consistent.

The change from past tense ("powered") to present ("powers") correctly reflects that TypeBox currently provides Elysia's validation system. Using "the library" also properly establishes TypeBox's central role.

---

72-88: Validation explanation is clearer and more concrete.

The revisions better explain the union type limitation and the per-status validation improvement, making the practical impact clearer for readers implementing strict validation rules.

---

101-101: Migration guidance is clear and concise.

The refined phrasing makes it explicit that the only required change is explicit installation of @elysiajs/fn, helping users understand there are no other breaking changes to address.

---

104-115: Conditional Route explanations are more approachable.

The wording improvements make the purpose and behavior of the .if method clearer, and the em dash in line 106 improves readability of the example setup.

---

148-148: Validation error capability is clearly summarized.

The refined phrasing emphasizes the new flexibility in accessing multiple validation errors for custom API responses.

---

152-155: Bullet list improvements are grammatically accurate.

Pluralizing "types" and "responses" correctly reflects the scope of refactoring efforts and maintains consistency with the broader technical documentation style.
