What "source-checked" means
This is the most important thing to know about APiM Galaxy: "source-checked" has a precise, honest meaning, and understanding it is what lets you trust the map.

What a check actually confirms
How we check a relationship: we open the page it cites and confirm that both companies are named there. That tells you the source is real and names both — not that the relationship is confirmed. Anything that does not pass, or that cites no source, is shown dashed.

What the ✓ means
✓ = both companies are named on the page this row cites. It is a check on the source, not a confirmation of the relationship.

Why we hold this line
A machine reading public sources can be confident and still wrong. So we only claim what we can actually check — that a real source names both companies — and we flag everything else. It's a smaller promise, kept honestly, instead of a big one you can't trust. When a decision needs more certainty than that, a person should check the ground truth — that's what A Piece of Map's advisory is for.
A check on the source is not a verdict on the relationship. Use the ✓ rows as solid starting points, but always open the linked source yourself before anything high-stakes.
