Review

⚠️ 2 warnings found in commit a7367d0.

👉 Fix in your agent 👈

Fix the following review findings in PR #32346 (https://github.com/cloudflare/cloudflare-docs/pull/32346).

Before making changes, review each finding and present a brief summary table:
- For each finding, state whether you agree, disagree, or need clarification
- If you disagree (e.g. the fix requires disproportionate effort for minimal benefit,
  or the finding is factually incorrect), explain why
- If you need clarification before deciding, ask those questions
- Then share your plan for which issues to tackle and in what order

After triaging, follow this order:
1. Post a comment on this PR for any findings you are skipping, with the finding ID and your reasoning.
2. Then commit the fixes for the legitimate findings.

The comment must come before the commit — the bot reads PR comments when a new
push triggers a review, so skip comments posted after the push will be missed.

### Warnings (1)

#### CR-f3e6c0dca687 · Internal contradiction introduced by change
- **File:** `src/content/docs/ssl/reference/certificate-validity-periods.mdx` line 32
- **Issue:** The added table row states that 6-month certificates are available, but line 61 says "Cloudflare only issues certificates with validity periods of three months or less." These two statements conflict.
- **Fix:** Update the "Benefits of shorter validity periods" section (or its opening claim) to account for the new 6-month Enterprise/SSL.com option so the page remains internally consistent.
