Andy Matuschak: evergreen notes — atomic, concept-oriented, densely linked, accreting over time

Claim: Andy Matuschak's public notes (https://notes.andymatuschak.org) introduced "evergreen notes" — notes that "evolve, contribute, and accumulate over time, across projects" (updated 2023-07-13). The principles: atomic (one concept per note), concept-oriented (titled like APIs), densely linked.

Quote: "These notes are mostly written for myself: they're roughly my thinking environment."

Related framing (Matuschak, crediting Robin Sloan): "One of my favorite ways that creative people communicate is by 'working with their garage door up.'"

Confidence: Verified (primary).

Use for Candid: The methodology this very KB applies. Each entry here IS an evergreen note in Matuschak's sense. But: Brief 3 warns the "digital garden" label is a B2B liability — reframe as "research-backed knowledge base" in client-facing copy.
