Evidence inventory
What each source can actually establish
BulbMatch tracks 74 official and supporting sources. Being listed here does not make a source a complete product catalog. Its data must pass a parser test, a minimum-record check, and conflict review before it can appear as evidence on a page.
Registry and snapshots reviewed Aug 28, 2026The source is in the monitored registry and its parser contract passes a fixed fixture. “Checked” means the live endpoint also passed its minimum-record gate. Only model-level records with sufficient first-party fields can become public SKU evidence; index entries and historical certification rows cannot.

Publication rule
A parser can collect a fact. It cannot make the fact safe to publish.
- Prefer model-level first-party evidence over retail titles or category labels.
- Reject duplicate records when core fields disagree; never choose a convenient value.
- Keep unknown base, shape, voltage, or market fields unknown instead of inferring them.
- Queue affected articles for review when a source changes; never auto-publish generated text.
