### Decision
- **Merge Verdict: Mergeable**
- **Reviewed Scope:** Latest PR head
`a33b9ba275c9b79acb47f5663c9776c4bee8aeff`; local merge-base
`5c5270057cad39b8c252a1199b3f5959c3063bd2`; GitHub `/pulls/38741/files` matched
local `git diff --name-status` exactly with one file:
`.codex/skills/review-pr/SKILL.md`.
- **Not Reviewed Scope:** GitHub Actions/check-run status; real future
PR-review execution beyond static skill-instruction review.
- **Need Expert Review:** No mandatory expert review required.
### Basis
- The PR directly addresses the observed failure mode: local PR reviews can
accidentally use `base.sha..head.sha` or the current base tip as the review
boundary, which can include changes not shown in GitHub "Files changed".
- The new mandatory constraint makes GitHub PR metadata and
`/pulls/{number}/files` the authoritative review scope and requires local
file-list matching before reporting scope findings
(`.codex/skills/review-pr/SKILL.md:75`).
- The new "PR Diff Boundary Rule" gives a concrete, repeatable workflow
using `git merge-base`, triple-dot semantics, and a GitHub file-list
cross-check (`.codex/skills/review-pr/SKILL.md:88`).
- The coverage statement now requires future reviews to record the latest
head SHA, merge-base SHA, and file-list match status, making this class of
mistake visible in every review output (`.codex/skills/review-pr/SKILL.md:257`).
- Risk scan found no behavior/config/API impact on ShardingSphere runtime
code. This is a Codex skill documentation/process change only.
### Verification
- Reviewer-run local scope verification:
- GitHub `/pulls/38741/files`: 1 file, `.codex/skills/review-pr/SKILL.md`.
- `git diff --name-status
5c5270057cad39b8c252a1199b3f5959c3063bd2..refs/remotes/pull/38741/head`:
matched the same single file.
- `git diff --check
5c5270057cad39b8c252a1199b3f5959c3063bd2..refs/remotes/pull/38741/head` passed
with no output.
- No Maven tests were run because the PR only changes a Codex skill Markdown
file and does not touch ShardingSphere production/test modules.
- No GitHub Actions, CI status, or check-run completion was used for this
verdict.
