Doctrine: every dossier cover illustration must be sourced, not blind-prompted. Each visual element (founder, building, signature object, brand color) traces to a real reference — photograph, interview, physical artifact, brand asset. Per-dossier figures/cover-sources.md documents: - the visual elements present in cover-prompt.txt - the source for each (URL, photograph, founder name, building, etc.) - founder + key people referenced (or deliberately not depicted) - what was excluded and why - citation log (URLs, ProPublica EINs, Wikipedia, primary docs) Covers 13 dossiers: rhizome, sfpc, eyebeam, recurse, internet-archive, mellon, pioneer-works, new-inc, studio-museum, hathitrust, the-kitchen, machine-project, heavy-manners-library. Cross-references called out: Kaganskiy (NEW INC → Eyebeam), Maya Man (SFPC supporter + Heavy Manners web designer), 1200 N Alvarado tenancy chain (Echo Park Film Center → Machine Project → Heavy Manners Library).
