opschain admin runner-attributes

Included from Basic tier

Manages the registered placement attribute keys — the vocabulary runner groups and placement selectors share. A group may only carry attributes whose keys are registered, a run may only demand registered keys, and a key with enumerated values accepts only those values; registration is what turns a placement typo into a write-time refusal instead of a silently unsatisfiable queue entry. The reserved keys location and network are seeded into every registry and cannot be removed.

Subcommand	Does
list	Registered keys and their allowed values — opschain docs cli/admin-runner-attributes-list
set	Register a key, optionally enumerating its values — opschain docs cli/admin-runner-attributes-set
remove	Unregister a key (reserved keys refused) — opschain docs cli/admin-runner-attributes-remove

Attach registered attributes to groups with opschain admin runner-group set (opschain docs cli/admin-runner-group-set); how selectors match them is opschain docs fleet-queue.
