"""Pydantic v2 result schemas for MacroLens task runners.

These models replace the legacy ``TypedDict`` shapes used pre-Phase-4. The
orchestrator (:mod:`experiments.run_all`) persists results as
:class:`macrolens.RunRecord` (full reproducibility envelope); these
per-task models capture the *metric content* of a single record's
``metrics`` field and are used by post-hoc tools (``gen_tables.py``,
``analysis.py``) that need a typed handle on the per-task metric set.

Every model:

* Uses ``model_config = ConfigDict(extra="forbid", frozen=True)`` so unknown
  keys raise at construction and instances are hashable.
* Allows every metric to be ``None`` — runners that legitimately skip a
  metric (e.g., a deterministic naive method that does not report CRPS)
  emit ``None``, not a sentinel string.
* Adds T5/T6/T7 (the legacy schema was missing T5/T6/T7).
