`uv sync --no-sources` rewrites uv.lock in place (swaps the local editable
langchain-core/-tests source for the PyPI registry), so the post-test
`git diff --exit-code` guard saw an expected diff and failed. Scope the
guard to ignore uv.lock; it still catches stray files written by a test.

Docs-only release: removes the internal "Releasing" section from the
public README (it lives in CLAUDE.md as of 8b4a1e7, but 0.1.0 shipped
before that) and adds the CI badge. Library source is unchanged from 0.1.0.

README is now the canonical, complete reference (all 12 components plus a
components-reference table). The LangChain provider page is generated from it by
the sync-langchain-docs skill (README -> MDX), replacing the deleted
docs/provider.mdx as canonical; sync.py is trimmed to docs-repo path resolution
(--path/--repo).

Add Vale prose linting in lockstep with the docs-repo house style: .vale.ini
and .github/vale/styles/ copied from langchain-ai/docs, a 'make lint_prose'
target, a gitignored PostToolUse hook (.claude/) that lints README.md after
edits, and CLAUDE.md documenting the 'lint the README after any change'
convention. Docs-parity tests are retargeted from provider.mdx to README
(test_readme_parity.py, test_readme_examples.py unit+integration, tests/readme.py
helpers); tests/docs.py and test_docs_parity.py are removed.

Also includes pending working-tree changes to the package, tests, and examples
(client-only base refinements, tool kwargs, the dql_explorer web app, and the
quickstart notebook).

…throughout user-facing code

The langchain-ai/docs CI flags langchain_core imports that have langchain
re-export equivalents (messages, tools). Fixes the docs PR check by sourcing
from langchain.messages / langchain.tools in README, examples, and tests.
langchain added to the test dep group so the ChatDiffbot README block stays
executable in the unit suite.

- Remove Vale config (.vale.ini, .github/vale/styles/) and the
  lint-readme PostToolUse hook — prose linting now runs in the docs
  repo only, with findings propagated back here manually
- Remove lint_prose Makefile target
- Update CLAUDE.md Documentation section to describe four equally-weighted
  docs surfaces (README, providers hub, tools page, retrievers page) with
  no single source of truth
- Rewrite sync-langchain-docs skill: reads all four files before acting,
  updates whichever need it, links instead of duplicating within langchain-docs
- Add audit-langchain-docs skill: runs docs-repo Vale, checks API coverage
  and import freshness, propagates fixes back to README.md and Python source
- README: drop prose-linting section; update Authentication section wording

Rework docs strategy: parallel maintenance, remove Vale, add audit/sync skills

Reformat DIFFBOT_ONLY_IMPORTS to satisfy ruff E501, and add the published
integration docs URL near the top of the README.

Expand sync-langchain-docs to cover all six doc surfaces, drop README-as-
source-of-truth wording, and record which imports use langchain vs langchain_core.

COMPANY_RESEARCH_MODEL and DQL_EXPLORER_MODEL are both read by the example
agents but were never mentioned in the template, so the only way to discover
them was reading agent.py. Mirrors the same block in the TypeScript package.

Byte-identical to examples/.env.example in the TypeScript package: the two API
keys you must set, plus optional LangSmith tracing. The model-override vars are
still read by the examples and documented in their READMEs, which is where
someone tuning one is already looking.

Builds the wheel and sdist on a v* tag, verifies the tag matches
pyproject.toml's version before anything is published, then publishes to PyPI
and cuts a GitHub Release. workflow_dispatch runs build-and-verify only, so a
manual run can never publish.

Also installs uv in the release job. It runs on a fresh runner that neither
checks out the repo nor inherits the build job's setup, so uv was not on PATH
and `uv publish` would have failed on the first real tag.
