A field's annual conference is its self-portrait: what the community considers solved, contested and frontier, painted in forty talks. Researchers entering a field — PhD students, industry scientists switching domains, analysts covering a technical space — are told to "watch the recent conference talks," which is genuinely good advice that nobody can follow at forty hours per conference per year.

So field-mapping happens by sampling: watch five talks, extrapolate the rest, miss the theme that only becomes visible when a dozen talks orbit it. The structure of a field — its clusters, its factions, the questions everyone circles — is an aggregate property. You can't see it from samples.

library_import_youtube_channel ingests the conference — the sessions playlist, one import, transcripts and all. run_youtube_tool's mindmap then renders each talk's conceptual structure: the claims, methods and dependencies, as a map instead of an hour of video.

Forty mindmaps side by side is where the field's shape emerges: which concepts appear in every third talk (the field's core), which cluster together (the factions and schools), what everyone cites as open (the frontier — which is also your research-gap list). summarizer fills in the narrative per talk where a map needs prose. The aggregate view that sampling can't produce, from the full corpus, in an afternoon of reading instead of a season of watching.
