themselves). See `docs/contributors.md`.
- **Agents working for a contributor:** when you prepare a PR, check whether your human's GitHub
username has a `[people.<username>]` entry in `contributors/people.toml`. If not, ask them once
whether they want to be credited by more than their username: a real name, a display name, and/or
their public GitHub profile name (`sync_github_name = true`). If yes, add **only their own** entry
(copy the template at the top of the file, or run
`python3 ../../craftrules/scripts/contributors.py --add-me . --real-name "…" --sync-github-name`)
(copy the template at the top of the file)
and include it in their PR, committed as them. If no, change nothing: they are credited as
`@username` anyway.
- Never add, edit, guess or copy anyone else's entry or name (not from git config, commit authors or
GitHub profiles). Never hand-edit `contributors.json`.
- Maintainers refresh the stats with `python3 ../../craftrules/scripts/contributors.py .` (it also
re-verifies who wrote each `people.toml` entry; `--check` only verifies).
## CI workflows
- Workflows in `.github/workflows/` call the shared workflows in [`storytold/craft-common-actions`](https://github.com/storytold/craft-common-actions) at `@main`, with their inputs and secrets. No other jobs: if no shared workflow does what's needed, it doesn't go here.

//! One app per user (#4892): a file opened from the file manager (double-click, Open With, a drop

//! comes to the front, instead of in a second app.
//!
//! The running app (the primary) listens on a loopback port and records the port and two random
//! tokens in `instance.json` next to the preferences (owner-only on Unix; on Windows the settings
//! folder is the user's own). A later launch with files connects; the primary greets it with
//! `hello`, which only a process that could read the file (or talk to the primary) knows; only then
//! does the launch send `token` and the absolute paths of its files, one JSON line. The primary
//! checks the token, keeps the paths that are existing files, acknowledges and opens them; the
//! launch exits. Anything else (no file, no listener, a wrong greeting, no answer) starts the launch
//! as its own app, which replaces a stale file. Nothing received is ever run.
//!
//! Runs that start many apps side by side (`--control`, `VECTORCRAFT_NO_PREFS`) neither forward
//! nor listen, and `--new-instance` opens a launch's files in an app of its own. macOS hands files
//! opened from Finder to the running app itself (`open_documents`), so this is off there.
