The `add_texts` method in `langchain-core` does not raise a `ValueError` when the number of provided IDs does not match the number of texts, despite the docstring stating otherwise. This leads to silent data loss as extra texts are discarded via `zip(strict=False)`. A regression from commit `6dd9f053e3` removed explicit validation.
In langchain-anthropic's _format_messages, when an AIMessage contains both a tool_use content block and a matching tool_call in the structured tool_calls field, the tool_use block is rebuilt from tool_calls and any extra keys on the original block, notably cache_control, are discarded. This causes prompt-cache breakpoints placed on tool_use blocks to be silently lost.
