Phases

Configuration: odoo.conf, CLI flags, env vars.
Database: check, create (if init), connect.
Modules graph: resolve dependencies, install/upgrade as needed.
Registry build: import Python files, register models, fields, methods.
HTTP server: start in single-process or multi-worker mode.
Services: cron, longpolling bus, reports, i18n.

Workers Modes

Single worker (dev): everything in one process (default here).
Multi worker: master + workers via --workers N.
