Pick any line to see why it is the way it is: the commit, the pull request and issue it came from, and what the agent was thinking.

The docs service answers every artifacts call: docs can be made, listed, shared, moved, trashed, restored, searched, versioned and edited live in their own rooms, agents read, write and recall them only where their person and everyone in the conversation can, and folio events go out on the bus, while Docs' pages keep working as before.1d ago		1	/**
		2	* What an agent may reach in folios for the person it acts for (its
		3	* asker), and who else will see its answer (the audience): the leak rules
		4	* of docs/ARTIFACTS_MODE.md section 4.3, apart from where rows come from.
		5	* Pure.
		6	*
		7	* - The agent never has more than its asker (`agentFolioRole`).
		8	* - Finding things (lists, search, recall, stale) is narrowed to folios
		9	* every person in the audience can read, so nothing turns up in a
		10	* conversation that someone in it can't open.
		11	* - A public channel's audience is "the workspace": only folios readable
		12	* through an open space or general access `workspace`. Never a link
		13	* folio, a share, or Private. More than 20 people reads the same way.
		14	* - Reading one folio the asker named (a link they gave) works whenever
		15	* the asker can read it; the result says `audience_can_read: false`
		16	* when someone else in the conversation can't, so the agent says it
		17	* sent the link to the asker instead of quoting it.
