Writing The Notebook Practice: Greene's instruction is to capture every stray fragment unfiltered — no theme, no chronology, "drawings, quotes from other books, anything at all" — specifically because relevance is only visible in hindsight, and a notebook that's pre-sorted defeats its own purpose. That's not a description of a personal habit. That's a description of what this vault's CLIPPINGS-to-RAW-to-ARCHIVES pipeline is for.
[RESONANCE]There's something quietly strange about ingesting a 2012 self-help book into a 2026 personal knowledge system and finding, embedded in its own pages, an accurate account of the system doing the ingesting. Greene wasn't describing Obsidian vaults or second-brain software — none of that existed in its current form when he wrote this. He was describing Leonardo, Proust, Einstein, Darwin, and Faraday's paper notebooks. The vault and the historical practice converged independently on the identical bet: capture cheaply now, filter expensively later, because filtering at the moment of capture throws away exactly the material that turns out to matter.
This is the strongest kind of cross-domain handshake the CLAUDE.md gate is designed to protect — not "these two things are both about creativity," but a specific, checkable mechanism (unfiltered capture beats pre-sorted capture, because relevance is retroactive) independently discovered by five historical figures with no access to each other's methods, and now discovered a sixth time by whoever built this vault's own workflow, also without deliberately modeling it on Greene.
Is there a genuine risk the vault is over-filtering somewhere Greene's five cases weren't — the CLIPPINGS triage step specifically, which does apply judgment (INGEST NOW / HOLD / SKIP) before material even reaches RAW? Greene's Masters kept everything, unfiltered, in the notebook itself; the vault's own pipeline filters once, at triage, before material is even staged. Worth asking whether that first filter is quietly discarding exactly the "seemed irrelevant at the time" material Proust's own notebooks (twenty years of scraps before In Search of Lost Time) suggest is disproportionately valuable.
Raise as an open question in META/open-questions.md: does CLIPPINGS triage's SKIP category risk discarding material that would only reveal its relevance in hindsight, the way Greene's five Masters' unfiltered notebooks did?
