- **langchain.schema.*, langchain.prompts.*, langchain.callbacks.base, langchain.output_parsers (base)** → `langchain_core.{messages,documents,prompts,callbacks,output_parsers,runnables}` (2 sites): Base abstractions moved to langchain-core.
Files touched: 1.
Deterministic rewrites from a machine-readable MigrationSpec for this upgrade, then a review pass on the semantic residue; every changed file was parsed and checked with pyflakes for new undefined names before this PR was prepared. No behaviour beyond the migration was touched: no reformatting, no import reordering, no unrelated code.
Happy to adjust anything — if the project deliberately pins the old major version, say so and I will close this.
