 ## 6. Code Review Comments
-- [ ] **Specific Linking**: Comments should be linked to specific code. Try to avoid general comments about the entire pull request.
+
+### 6.1 Posting Comments
+- [ ] **Code-Linked Comments**: Every review comment **must** be anchored to a specific file and line range using the Gitea inline comment API (`path` + `new_line_num`/`old_line_num`). Free-floating general comments are only acceptable for summary notes that cannot be attributed to a single location.
+- [ ] **Severity Prefix**: Prefix each comment with its severity so the author can prioritize: `🔴 Blocking`, `🟡 Design/Architecture`, or `🟢 Minor/Suggestion`.
+- [ ] **Actionable Guidance**: Each comment must include a concrete, actionable suggestion — not just a description of the problem. Where applicable, provide a corrected code snippet.
+
+### 6.2 Resolving Comments (Author Responsibility)
+- [ ] **Reply Before Resolving**: When a review comment has been addressed, the author **must** reply to the specific thread explaining *how* the issue was resolved (e.g., commit SHA, approach taken, or a reasoned rejection with justification). Do not close a thread without a reply.
+- [ ] **Link to Fix**: If the resolution is a code change, include the commit SHA or a reference to the changed line in the reply (e.g., `Fixed in abc1234 — moved the guard before CTS allocation`).
+- [ ] **Close Only After Reply**: Mark a thread as **Resolved** only after posting the reply. A thread with no reply must remain open, even if the underlying code has changed.
+- [ ] **Rejection Must Be Justified**: If the author disagrees with a comment and chooses not to act on it, they must reply with a clear technical justification. The reviewer then decides whether to accept the reasoning and close the thread, or escalate it.
