Attribution relies on the extraData tag each builder voluntarily stamps. A builder can change or strip its tag; unrecognized tags land in Other and raw strings are logged so the table grows. The Vanilla row (locally built) could be marginally overstated if a builder uses a client-default tag; the relay cross-check surfaces this. High share is a centralization datapoint, not a quality ranking.

How this pair was selected

Auto-generated pairs require: both providers in the same benchmark for seven consecutive days, at least 1000 samples per provider, observable third-party search demand, and a public /products/[slug] page on OCB. Editorially curated pairs (like this one) may publish early when search demand is high and data is accruing — panels with fewer than 100 samples are shown as provisional. The full pair ledger is versioned in the public repo.
