How much of the specification you have seen — and how much you have proven with marked practice. Seeing is not proving; the bars keep the two apart.
Reading the syllabus map and joining your evidence…
Proven means marked evidence exists for the point — a marked attempt (or, on a signed-in account, the covering topic's measured skill). Seen means you engaged with the point's content — read its notes, rated its cards — which is self-report evidence and never mastery: exposure only, never proven.
Where the data lives: the syllabus map is the course's own specification graph; your evidence is this browser's local progress lane (the same lane the knowledge graph reads), or your live account when one is connected. Nothing here is invented — points the evidence join cannot attribute render as not started, and if a source fails, the page says so instead of showing zeros.
