A thought, a link, a photo, a voice note. Drop it into a synced folder from anywhere, and it is waiting in the inbox at the next session. One command writes it up, ready for you to place. Capture now, sort later, never lose it.
Save anything into a synced folder from your phone.
A hook moves it into the vault inbox, not yet sorted.
You run process-inbox; it classifies it and writes the note.
It comes back at the next review, for you to place.
One item per file, no formatting needed: a markdown note, a URL, a PDF, a screenshot. The mechanism is your choice. A folder kept in sync by something like Dropbox is plenty, and a small script on your phone to save into it is a fine stop-gap to start with; a more elaborate pipeline can come later, if you ever fancy building one.
does the groundwork, under the vault's mutating lock so two sessions never sort the inbox at once, and raw drops are retired once captured so the inbox always reads as just the things still waiting. It stops deliberately short of filing: almost everything lands fully prepared in a staging area, due at once rather than on a date of its own, so nothing sits there quietly earning a later look. Only project-outline updates assimilate on their own. Nothing watches the clock in the background; instead the next pass, or simply asking what is due, surfaces what has arrived, grouped by how long it has been waiting, and each gets a quick decision: keep it, push the date out, develop it into something, or let it go.
How the lock fits with the other concurrency mechanisms
Capture and triage are split on purpose. The capture takes a second on your phone; the filing is a separate, on-demand pass rather than a cost forced onto every session. Running it synchronously would tax the session you actually opened: it spends time and tokens, and it holds the vault's mutating lock while a rarely-urgent queue is worked, so the work you sat down to do waits behind it. Kept apart, a passing thought never depends on you being at your desk, and no session pays for an inbox it did not ask to process.
