```python
class tensorplay.export.CustomDecompTable(entries: Mapping[Any, Callable[[...], Any]] | Iterable[tuple[Any, Callable[[...], Any]]] | None = None, *, defaults: bool = True)
```

A validated mutable mapping from graph targets to replacement callables.

Entries are keyed by graph target (callable or method name).  Removing a
key preserves the op from rewriting; materialize returns a plain dict
for consumers that require one.

```python
clear() → None.  Remove all items from D.
```

```python
classmethod fromkeys(iterable, value=None, /)
```

Create a new dictionary with keys from iterable and values set to value.

```python
materialize() → dict[Any, Callable[[...], Any]]
```

Return a plain dict of effective entries, resolving defaults.

```python
popitem()
```

Remove and return a (key, value) pair as a 2-tuple.

Pairs are returned in LIFO (last-in, first-out) order.
Raises KeyError if the dict is empty.

```python
remove(target: Any) → Callable[[...], Any]
```

Preserve target by deleting its decomposition entry.

```python
setdefault(key, default=None, /)
```

Insert key with a value of default if key is not in the dictionary.

Return the value for key if key is in the dictionary, else default.
