"""Publiciste Agent · orchestrateur CLI (scaffold Sprint 2).

Cible de portage sur le VPS : `otoia/capabilities/publiciste.py`
(cf. 03_agents/publiciste/AGENT.md · GAP_ANALYSIS_SPRINT1.md §3.13).

Maintient le site public `vente.otov7.com` À PARTIR DES FAISABILITÉS CANONIQUES
(data_room/PXX/), sans édition manuelle. Zéro invention de chiffre (CLAUDE.md #6).

Sous-commandes :
  parse     data_room/  -> projets_master.json (validé contre le schéma)
  validate  projets_master.json
  generate  projets_master.json -> index.html
  run       data_room/  -> projets_master.json + index.html (pipeline complet)

Pipeline (AGENT.md §Architecture technique) :
  data_room/PXX/ ──► parser ──► projets_master.json ──► generator ──► index.html

⚠ Ce worker n'écrit JAMAIS sur le VPS. La commande `run` produit les artefacts
dans un dossier de sortie local ; le déploiement réel (copie vers
/opt/oto/sites/vente/ + cache-bust + WhatsApp) est un livrable ultérieur exécuté
côté serveur par l'agent (Semaines 4-5).
