Fix each module's single pre-existing type error with a pure annotation or setattr change (no behavior change) and remove it from the [[tool.mypy.overrides]] ignore_errors list: - callbacks/train_logging: loss_trackers: dict[str, MeanMetric] - callbacks/metrics_logging: seen_examples: set[str] - common: setattr(wrapper, "_has_run", True) for the @wraps wrapper - hydra/resolvers: attribute_path: str | None (body already guards) - inference_engines/base: base_overrides: dict[str, Any] 13 modules remain on the ignore list. mypy now type-checks the 5 newly-included modules cleanly.

Resolve the type errors in and remove from the [[tool.mypy.overrides]] ignore_errors list. Mostly narrowing / annotation fixes; two deliberate type-honesty fixes flagged below. - utils/weights: lowercase `any` -> `Any` in _PatternPolicyMixin (4x); assert-narrow fallback_policy at the call site (matches get_policy idiom) - model/layers/blocks: class-level w/b: torch.Tensor for the registered buffers (avoids nn.Module's Tensor | Module __getattr__ fallback) - utils/components: is-None narrowing + tip_names local in get_name_mask's TIP branch (exists() can't narrow for mypy); drop orphaned exists import - utils/logging: str(field) for the tree key; assign to a new hparams local rather than reassigning the typed cfg param - foundry_cli/download_checkpoints: guard on `hasher is not None`; total_size = 0.0 for the float accumulation - training/schedulers: SchedulerConfig.scheduler is now a required field (was = None, but documented required and assumed non-None everywhere) - utils/xpu/xpu_accelerator: name @Property -> @staticmethod to match lightning's Accelerator ABC 6 hard-tier modules remain on the ignore list.

Type-checking: resolve the type errors in 7 modules and remove them from the
[[tool.mypy.overrides]]ignore_errorslist (13 → 6 remaining), so mypy now type-checks them.Most fixes are local narrowing / annotation work. Two are deliberate type-honesty changes, each touching only an unused or impossible path:
SchedulerConfig.scheduleris now a required field (was= None, but documented required and dereferenced unconditionally instate_dict/load_state_dict; every construction site passesscheduler=...). A bareSchedulerConfig()now raises instead of building a broken-on-first-use object.XPUAccelerator.name@property→@staticmethod, to match lightning'sAcceleratorABC (@staticmethod @abstractmethod def name() -> str). No foundry code reads.name; lightning calls it per its own contract.Per-module details are in the commit message.
