Bounded H1 command examples

Follow the command walkthrough for complete checkout and fresh content-verified installation commands, pinned runtime requirements and Linux/Windows private-file creation. pure.zry returns WIT ok(()); error.zry returns err(()); lookup.zry has one literal MODE environment lookup and requires a matching explicit caller-private request. Pure source rejects a grant file. No ambient environment value is read and no additional capability is granted.

These examples map to the two command modes in the M4 matrix. Existing immutable beta archives remain excluded. Content verification does not establish a signed package release or production admission. A runnable example and a successful process exit do not authenticate complete both-host M4 evidence or live publication.
