This is a clean docs + JSDoc refresh. No correctness bugs, security issues, or type-safety problems found. The generated files (api-docs.json, llms-full.txt) were skipped per review scope.

Source files (licensing/telemetry) — The JSDoc additions to evaluateLicense, emitNag, runLicenseCheck, provideThreadplaneTelemetry, and ThreadplaneTelemetryService are accurate and match the implementation. The new ThreadplaneBrowserStreamErrorTelemetry interface doc correctly notes that error?: unknown is reduced to an error class before sending, which is the right thing to call out explicitly.

New guide: python-langgraph.mdx — Technically accurate. One minor inconsistency: the "Helper surface" import block includes bind_client_tools and route_after_agent alongside the lower-level utilities, but the table below it only documents the lower-level five. This mirrors the TS guide's structure, but there the section is explicitly labelled "Lower-level helpers"; without that label here, a reader scanning the table for route_after_agent won't find it. Renaming the section heading to "Lower-level helpers" (matching langgraph-client-tools.mdx) would resolve the inconsistency. Not blocking.

Fix this →

docs-config.ts — The new python-langgraph slug and updated API-reference title are consistent with the new MDX files.

llms.txt/route.ts — Python package line and install snippet are correctly added.

packages/threadplane-middleware/README.md — The updated dev command (uv venv + uv run --extra test python -m pytest -q) is correct; uv run handles implicit sync so the explicit uv venv is optional but harmless.

Overall this looks good to merge.
