 // Snapshot tests: `pnpm run test:snapshot`, file pattern *.snapshot.ts.
-// REPLAY by default — they boot the real acp-agent subprocess against a
-// recorded session JSONL fixture (no API key, no network) and diff the
-// normalized stdout transcript + re-persisted log against committed goldens.
-// `pnpm run test:snapshot:record` (DSH_SNAPSHOT=record + -u) re-records the
-// fixtures against the real API and refreshes the goldens.
-// `pnpm run test:snapshot:refresh` (DSH_SNAPSHOT=refresh) stays keyless: it
-// replays the committed model scripts and writes the current stdout/log goldens
-// without calling the live LLM.
-//
-// Replay loads no .env (it must never reach the network — a recorded fixture
-// drives the model), and refresh uses that same keyless replay path. Record
-// reads DEEPSEEK_API_KEY from the env or a gitignored repo-root .env, so a
-// contributor with a key only in .env can still record.
