PR #5: test: whitespace-only README change

No review output produced.

Decision

• recommendation: request_changes
• summary: Block auto-merge: the PR is not whitespace-only, adds trailing whitespace, and repo policy disables auto-merge.

Reasons

• The diff is not whitespace-only: it changes README keybinding text from Ctrl + \ display intent to doubled backslashes in two lines.
• The commit introduces trailing whitespace in README.md, which git show --check flags.
• Repository merge policy says merge.enabled=False, so this PR is not eligible for auto-merge even with green CI.

Risks

• Auto-merging would violate the stated merge policy.
• The PR description is misleading relative to the actual diff.

Required Actions

• Remove the non-whitespace README content changes or update the PR description to accurately reflect the behavioral/doc change.
• Remove the trailing whitespace in README.md.
• Do not auto-merge while merge.enabled is disabled; use a human-reviewed/manual path if this PR still needs to land.

Merge Gate

Result: blocked

Reasons:

• merge is disabled by configuration
• model recommendation is request_changes, not merge

PR #5: test: whitespace-only README change

The diff only updates README formatting and escapes backslashes in documented keybindings. These changes do not affect runtime behavior or introduce a correctness issue.

Decision

• recommendation: request_changes
• summary: Block auto-merge: the patch is not whitespace-only, introduces trailing whitespace, and repository policy disables auto-merge.

Reasons

• git diff main...63b8f297 shows this is not whitespace-only: it also changes documented keybindings from Ctrl + \ rendering to doubled backslashes in two README lines.
• git show --check 63b8f297 flags trailing whitespace in README.md, so the patch is not clean.
• Merge policy context says merge.enabled=False; that blocks auto-merge even with passing CI.

Risks

• Auto-merging would bypass the stated repository merge policy.
• The PR description is inaccurate relative to the actual patch content.

Required Actions

• Remove the trailing whitespace in README.md.
• Either revert the non-whitespace README content changes or update the PR description to match the actual diff.
• Do not auto-merge while merge.enabled=False; use the required manual path if this change still needs to land.
