   - cargo test
 - The test suite includes CLI-oriented integration tests and unit tests. Some tests simulate GPU detection using env vars (POLYSCRIBE_TEST_FORCE_*). Do not rely on these flags in production code.
 
-Examples check (no network, non-interactive)
-- To quickly validate that example scripts are wired correctly (no prompts, quiet, exit 0), run:
-  - make examples-check
-- What it does:
-  - Iterates over examples/*.sh
-  - Forces execution with --no-interaction and -q via a wrapper
-  - Uses a stubbed BIN that performs no network access and exits successfully
-  - Redirects stdin from /dev/null to ensure no prompts
-- This is intended for CI smoke checks and local verification; it does not actually download models or transcribe audio.
