Reference framework: audience layering — foundation research vs public article vs marketing page (3-column comparison)

The three layers of a research-first content operation, side by side:

Dimension Foundation Research Public Article Marketing Page
Primary audience Future self, internal team, AI agents indexing the KB Prospects evaluating expertise; peers; journalists Prospects making a decision
Implied secondary None — written as if no one is watching Skim-readers, AI engines, search crawlers Sales conversations, AI shopping assistants
Length Atomic notes 50-500 words each; clusters 5,000+ 1,200-3,500 words 200-600 words
Tone Telegraphic, technical, hedged with confidence labels Narrative, opinionated, conversational Direct, outcome-framed
Source treatment Every claim cited inline with URL + date + confidence Named sources in prose; key citations linked; confidence smoothed One or two anchor citations; rest deferred to linked article
Update behavior Continuous; notes evolve Versioned with visible "last updated" Rewritten when underlying article changes materially
Failure mode if skipped Articles repeat received wisdom; no compounding Marketing pages assert without defending Articles get traffic but no conversion or trust
Closest analog A researcher's lab notebook; a Zettelkasten A New Yorker feature; Bits about Money Stripe docs landing page

The Candid KB occupies the Foundation Research column. The Candid public site (candidcreative.ca) occupies the Marketing Page column. The Article column is the missing layer — the place where Candid writing for prospects gets derived from KB research. Brief 14 is the architectural argument for filling that layer.
