The perf VM has no calternal-media-sandbox launcher on PATH. Read-only check during the locked rec1540c measurement phase: command -v calternal-media-sandbox returns missing.

Both baseline 4ebeba0b8 and candidate 9dd286c8e log this startup diagnostic:

ERROR calternal_plugin::media_sandbox: native media command failed; check runtime and service limits for launcher failures cause=Launch

Evidence: #1540 paired startup samples A1/B1 and A2 use a real 100,000-file text Home. They reach /healthz readiness with complete Files/MIME projections and graceful shutdown, but native-media availability is not verified by this environment. The launcher error is separate from SQLite contention and occurs with both binaries.

Prepare the supported native-media runtime on the perf VM or make its preparation an explicit prerequisite of the server performance profiles. Keep the sandbox protections. Verify the sealed JPEG startup decode and a real document preview after preparation. Do not change the environment in the middle of the active paired run.

Related: #1540, DESIGN §§2 and 39; launcher health is documented under #988 and #1045. No production media or UI behavior changed in rec1540c.
