Private and unfinished work cannot move between accounts or computers. Private lab sessions and ideate verdicts live only in the running account's own owner-only stores (~/.abcd.noindex/lab/<root-sha>/ and ~/.abcd.noindex/ideas/<root-sha>/). Unfinished work lives in local branches and store worktrees: commits not yet on origin, uncommitted diffs, untracked files and each worktree's local-tier notes. A person who moves to a second account or computer, or hands work to a colleague's account, can carry none of it over except by hand: a git bundle of the branches, a patch and a tarball per dirty worktree, and a hand-written status table and handover note saying which branch is which and what comes next. That route skips redaction, integrity checks and the owner-only modes the private stores rely on. It also says nothing about what cannot travel: preflight receipts, implement-loop run state and reservations held by the old checkout. On the receiving side nothing ingests the material, so later lab, ideate or build runs there cannot read it, and it does not stay private by default.

Grounds

• pursued: we expect one pack-and-receive pair to replace the hand-built bundle, patches and handover note; a handover that still needs a hand-written note to be usable shows it wrong
