First-party plugins (host_agent, http, snmp, traefik, unifi, docker) are now tracked under plugins/ and baked into the image, so they version atomically with core — ending the cross-repo import drift the roundtable->steward rename exposed. History for these files is preserved in the archived Roundtable-plugins repo. Plugin discovery becomes multi-root: PLUGIN_DIR (single) -> PLUGIN_DIRS (bundled first, then external) + PLUGIN_INSTALL_DIR. Bundled ships in the image; third-party plugins still mount at runtime into the external root (STEWARD_PLUGIN_DIR, default /data/plugins) and downloads/installs land there. Bundled shadows external on a name collision. - config.py: load_bootstrap returns plugin_dirs + plugin_install_dir - app.py: iterate PLUGIN_DIRS at the migration + load sites - migration_runner.py: discover_all_in() unions every plugin root - plugin_manager.py: resolve_plugin_path() (pure, first-root-wins); load / install / hot-reload span all roots; installs target the external root - settings/routes.py: _discover_plugins scans all roots, dedup bundled-first - Dockerfile: COPY plugins/ ; docker-compose: drop host bind, document external - tests/test_plugin_dirs.py: resolution, multi-root discovery, bootstrap split Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
