A run a teammate asks for now says who asked and what ran it, on both sides.

• The run card's byline credits the asker and names the machine and key: the owner reads asked by octocat · ran on your H72Q5YQ4CG with your key. The guest reads asked by you · ran on sam's H72Q5YQ4CG with their key. Hosted and cloud channels name their workspace and service instead.
• Team pulse credits a run's end to ran.author, the person who asked, rather than the channel owner. A teammate's run in your own channel now shows under them.
• When a teammate's run ends in your channel while you aren't watching it, the owner gets a notification (rivera used your agent, plus , and the run failed when it failed), or the window glows.
• A guest's Agent access tooltip names the owner and machine (run commands as sam on H72Q5YQ4CG, with sam's model keys…) instead of "as you on this machine".

Fixes #601. Map: ^587, ^431, ^619.

Smoke test on an isolated host (own ACE_HOME, port 4731, --loopback --demo) with a synthetic teammate who really asked @ace, using a real Anthropic model:

• Owner view: the card byline and Team pulse (octocat · Here / Finished in #w3chan) both showed the expected text.
• Guest view (the channel's owner was changed to another login on disk): both cards showed the guest wording, and the tooltip showed the new copy.
• Not tested: the owner's desktop notification. Headless Chromium has no desktop bridge.

Built in Ace

Made from Claude Code (a fix-train worker), not in Ace, because it was run headless as a parallel agent with its own isolated host. Gap tracked in the dogfooding meta issue, #5.
