The form opened with the four main versions already ticked, so the plan showed four VMs nobody had asked for. F5 on an untouched form would have created them. Deploying is expensive and hard to undo — the list now starts empty and the choice is made, not inherited. The « * » still marks each distro's main version, and F7 ticks exactly those four in one keystroke, so nothing is lost but the presumption. With an empty list a « 0 VM · 0 vCPU » total teaches nothing, so the footer says what to do instead: tick what to deploy, F7 main versions, F6 all. Verified headless: no box ticked on open, F5 producing no spec at all, F7 giving back the four, and the ticks surviving a switch to « all architectures » (4 of 30) since identity is distro/version/arch, not rank.

"""Formulaire Textual de déploiement QEMU, et vue de progression.
|
|
|
|
Deux interfaces mènent au même déploiement : les invites en ligne de
|
|
`todo.py` et ce formulaire. Toutes deux produisent la MÊME structure — la
|
|
« spec » — que `TODO._qemu_run_spec` consomme. Rien n'est décidé ici qui ne
|
|
puisse l'être là-bas, et réciproquement.
|
|
|
|
- build_vms(...) / plan_rows(...) : logique pure, testable sans terminal.
|
|
- run_deploy_form(ctx, run_app=True) : le formulaire ; renvoie une spec ou None.
|
|
- run_deploy_progress(jobs, ...) : blocs repliables par VM pendant le
|
|
déploiement, avec copie du log vers le presse-papiers (OSC 52).
|
|
|
|
Le formulaire ne lance AUCUNE commande privilégiée ni réseau : tout appel
|
|
`virsh` passe par sudo et une invite de mot de passe casserait l'affichage
|
|
Textual. Les données coûteuses (domaines existants, branches distantes) sont
|
|
préchargées par l'appelant et arrivent dans `ctx`.
