Large-workspace context reduction and board-linked campaigns

Umbrella manifests stay on disk. Agents receive summaries, pages, and search hits.

Caps (defaults)

Surface	Default page	Opt-in full dump
Workspace map / pack map	80 repos	--max-map-repos / ?limit= / limit: 0 on list
workspace list repos_index	80	--limit 0
workspace repo list	80 slim rows	--detail full (single-project) + --limit 0
Session digest rows	40	scoped --project/--repo
Campaign status / expand / board-sync	40	--offset pages
Full .metagit.yml JSON	refused above 80 repos	--confirm-full / ?view=full&confirm=1

workspace list does not embed summary.workspace unless --include-workspace.
