Assert that there is at least one error-level diagnostic for the given URI.

Parse finished; ASTContext is usable but diagnostics may still contain errors.

Lookup the symbol hash at a given annotation offset in any merged index.

Send clice/queryContext extension request.

Add a file with an optional content (relative path, auto-prefixed with root()).

Send clice/switchContext extension request.

Invoke all connected handlers synchronously, in connect order.

Send hover request at given position.

Assert the session produced zero anomalies (client messages + logs). Runs in every integration test teardown: anomalies are internal clice bu

Write a clice.toml that pins cache_dir to <workspace>/.clice/.
