A copy-link action that only appears when the link works
The Copy link to task action in a task's comment menu used to hand you a URL built from whatever address the app happened to be served from. In the desktop app that address is a loopback port on your own machine, so the link you copied looked like http://localhost:3847/tasks/… and opened nothing at all for the person you sent it to. The action promised sharing and quietly delivered a dead link.
It is now offered only where the address is genuinely reachable by someone else: a hosted Pekan deployment, whose own origin is by definition the one your colleague would use. There the copied link is the canonical task URL and opens the right task. In the desktop app the action is simply not shown any more. That is deliberate rather than a limitation we plan to paper over: the desktop knows the API and MCP addresses of the board it is connected to, but never the web address a person would open in a browser, so there is no correct link for it to build. Showing nothing is more honest than showing something that fails after you have already pasted it into a message. Copy comment text is unchanged and still available everywhere.
