Review the following {{language}} diff.

Focus on {{focus}}. For each finding give me the file and line, the risk in one
sentence, and the smallest fix that removes it. Flag anything that changes
behaviour without a test covering the new behaviour.

If the diff is fine, say so plainly instead of inventing nits.

What it produces

ClipboardStore.swift:126 — evict() runs before refresh(), so the
free-tier cap is applied against the previous fetch. A user who
downgraded keeps seeing 500 snips until the next launch.
Fix: swap the two calls.

No test covers the downgrade path.
