Drop jj-cli so Timeline is deckd-only; Hub keeps browse on screen across view transitions, rehashes live integrity at serve time, and walks four teaching stories. Co-authored-by: Cursor <cursoragent@cursor.com>
…oor. Drop the sans-serif landing so start sits on the same lattice as the lenses; the book link uses the current-tab fill instead of a footnote. Co-authored-by: Cursor <cursoragent@cursor.com>
…is deckd-only. Drop dual-read of per-pack import maps so ranges and entry live only in package.json, keep those maps as lineage, and lean the depot lock. History is deckd; the jj CLI backend is gone. Co-authored-by: Cursor <cursoragent@cursor.com>

Background and goal
Deck is now a package-native collaboration and delivery system rather than only an at-rest package experiment. A mutable package is a Repository; a grouped Repository advances several independently addressed packages atomically. Branches, forks, Checkpoints, Reviews, every-save History, exact previews, and merge facts all live inside the realm and are inspectable through Deck Hub.
This change also makes the Boxel backport executable: the protocol is RRI-native, local and S3 storage responsibilities are separated, the sample collaboration realm is rebuilt by replaying real CLI/API operations, and the Hub exposes the same state through Browse, Run, Track, and Review.
Where to start
docs/deck-collaboration-protocol.md— protocol objects and invariants.docs/deck-boxel-branch-index-backport.md— ordered Boxel backport and acceptance fixture.packages/core/src/repository.ts,repository-store.ts, andreview-store.ts— Repository, Checkpoint, branch-ref, Review, and merge mechanics.scripts/replay-collaboration.mjs— realistic multi-party workflow expressed as replayable operations rather than checked-in state.apps/hub/repository-service.mjsandapps/hub/hub/app/review/— the real Hub workflow and inspectable underlying objects.Key decisions and non-obvious mechanics
