Joined People UI and the Network-First Pivot — augment-it's sibling-flow to org-first augmentation, and the canonical/proprietary layer split underneath it

Org-first and people-first aren't two flows but two pivot points over the same org↔people join. A canonical layer (LinkedIn truth, refreshable, shareable across clients) split from a proprietary layer (this client's commentary, engagement-scoped, never shareable) — reads it against the CRM platforms that almost got it right (Attio, Affinity, Gong, SalesQL, Crawlbase), and lands on sub-scale plus domain-opinionated -- as the competitive position the big platforms structurally can't occupy.
