+# Core Ingest Golden Session Fixtures
+
+Each fixture directory contains:
+
+- `metadata.json`: fixture name, agent, ingest path, captured date, sanitizer notes, and session id.
+- `input.jsonl`: sanitized source data for the ingest path.
+- `expected.projection.json`: normalized `GET /v1/sessions/{session_id}` UI Ingest Projection.
+
+Normal tests never mutate snapshots. Refresh a fixture manually after reviewing sanitized input changes:
+
+```sh
+python scripts/refresh_core_ingest_snapshots.py --fixture codex/live/golden-session
+python scripts/refresh_core_ingest_snapshots.py --fixture codex/history/golden-session
+```
+
+To replace the tracer-bullet sample with a newly captured Codex Golden Session, update the relevant `input.jsonl` and `metadata.json`, then run the refresh command and review the JSON diff.
