A post's description is the snippet a search result shows. Two posts with the same one look like duplicates, and the second teaches a reader nothing about why to click. Earlier sweeps covered titles, h1s and meta length on product pages, but nothing compared descriptions across docs/posts/.
Across 937 posts, three pairs matched exactly:
- two posts on testing the Schedule AI worksheet, one of which was really about a real-browser test of the cash-basis profit and loss;
- two posts on the wall-framing soffit, fascia and J-channel card;
- a changepoint post on US inflation that carried the description of the Nottingham temperature post, which is a different dataset and a different finding. That one was plainly a paste error.
Each description now says what its own post says. platform/ci/check_post_frontmatter.py also fails when two posts share a description, with a test for it, so the next paste error is caught in the PR that makes it.
Not covered: near-duplicates (same sentence, one number changed) and duplicate titles, which were already unique.
