Can agents use it anyway?
Yes. Arbor produces the grounded brief; an agent can use that brief to write tests or keep a patch scoped.

FAQ
Common questions.
How Arbor walks PRs, how agents can use the brief, and how it fits a small-team workflow.
Does Arbor run my code?
No. The worker parses and walks source structure. It does not execute your app, tests, install scripts, or runtime commands.
What if the map is incomplete?
The missing edge is named in the PR so a reviewer or agent knows where the uncertainty is.
