Save briefs
Save briefs or strategist notes. Re-saving an id replaces its brief.
A brief may only quote numbers its evidence carries. Next-test ids come from the MCP surface's analysis (it ranks; REST does not); a free note takes an id note:<slug>.
Requires a key with write scope or higher.
MCP: meta_save_briefs.

Authorization has two independent axes.
The scope is ranked — a key satisfies any requirement at or below its own tier:
read— every GET.write— launch ads PAUSED, sync, pull history, edit thresholds, Values, briefs, tests, swipes and research.admin— everythingwritecan. No operation requires more thanwritetoday.
There is no approve scope. It was a rung once; it is not one now, and a key requested with it is rejected.
The approval grant (can_approve) is a separate boolean, not a rung. Changing spend on Meta — activating a launch, pausing or resuming ads, retargeting an ad set, or rebuilding a launch's live creative — needs write and the grant. Keeping them on separate axes is what makes the review gate a control rather than a convention: a key that may propose is not automatically a key that may approve its own proposal.
A key reaches the one workspace — one Meta ad account — it was minted in, and stops working when the operator who minted it leaves the workspace. The same key authenticates the MCP endpoint (/api/mcp) for a headless agent, with the same scope and grant.
