Closing. Re-authoring this onto current master would land a second, feature-regressing config loader: its from_yaml_file re-implements a yaml.load(open(...)) path that drops workspace_root, options/pin, rev/shallow/depth, worktrees, JSON support, and duplicate-workspace merging — all of which master's load_configs/ConfigReader pipeline handles.

Its two stated goals are already met on master:

• Type safety — the vcspull.types TypedDict graph (ConfigDict, RawConfigDict, RepoOptionsDict, RepoPinDict, …) gives mypy-checked config shapes with far more fidelity than the proposed dataclass.
• Filtering — vcspull.config.filter_repos already exists, and libvcs QueryList is usable directly.

The one genuinely novel idea — an eager object graph where Config.repos holds live GitSync/HgSync/SvnSync handles — is a real direction, but it belongs in a fresh proposal designed on top of today's load_configs/ConfigDict/update_repo pipeline (a migration touching ~10 consumer modules), not a rebase of a 2022 patch. Happy to revisit as a design doc.
