01Points where to go
In climbing: It marks the next point on unsupported terrain — knowing where to go is what lets you dare the next move.
In Anchors: The plan and the spec say what to build before the first line — the AI (or you) decides with direction, not in the dark.
02Holds the rope
In climbing: If you slip, the anchor becomes the safepoint that stops the fall — without it, one mistake would cost the whole climb.
In Anchors: The quality gates are that safepoint: they catch the divergence right away, so a mistake costs one fix — never the whole project.
03Marks where you’ve been
In climbing: The route stays recorded — whoever comes next doesn’t have to decode the wall again, just follow what’s already validated.
In Anchors: The dependency graph and the issue history do the same: the next session reads what’s already proven and continues from there — it doesn’t start from zero.
