Overview
Comment:feat(cli): report what each horizon rule would hold

Draft §3.4 asks a tool that suggests a horizon to show, before the choice, what each rule would hold in check-ins and bytes. repo cone cost <check-in> prints that for descendants and leaves from the local repository, and Repo.HorizonCost returns the figures. The --horizon help of repo clone and repo cone store points to it, noting that a clone has no repository yet.

Merge branch 'wip/repin-5d61' into feat/horizon-cones

The horizon draft pinned at zit horizon-rfc 5d618aaeb1: an origin with no tag in force mints no seed and serves the content level, and choosing C is shown with each rule's cost (repo cone cost, Repo.HorizonCost). check-in: 77e74bd011 user: [email protected] tags: feat/horizon-cones, trunk

docs(conformance): re-pin the horizon draft to zit 5d618aaeb1

The draft now says an origin mints no seed, and serves the content level, when no tag is in force at any check-in the seed would cover, since a control artifact needs a T card. HZ-5.2-2 loses its scope note and the new HZ-5.2-7 row is proven by a case that mints none, advertises horizon-served content and leaves the clone holding no seed. HZ-3.4-1 is restated as guidance for the tool; it is covered with the cost report in the next commit. check-in: 4e9dea8cc1 user: [email protected] tags: feat/horizon-cones, trunk
