| 4 | * and gets its registration token, through the page: |
| 5 | * |
| 6 | * 1. On every page, the page tells the app who is signed in, the |
| 7 | * workspaces they own (only owners add runners) and the one they are |
| 8 | * in (`offer`). The app answers with the workspace it wants a |
| 9 | * registration token for, if any, and asks again later (`onWanted`). |
| 10 | * 2. For that workspace, the page asks the server for a token |
| 11 | * (`POST /-/desktop/runner`, owners only, same origin) and hands it to |
| 12 | * the app (`register`), or says why there is none. It is never shown |
| 13 | * or kept here. |
| 14 | * 3. Whenever the runner's state changes, and every few minutes while g1t |
| 15 | * is open, the page sends the app's diagnosis to the server |
| 16 | * (`report`), so the workspace's Runners page lists every person's |
| 17 | * desktop with its state, why and the fix, in the app's own words. |
