# F13 runtime transcript

Production proof calls use each pinned checkout’s real `buildEnvironmentCaptureCommand` and `readEnvironmentFromLoginShell`, with exact `-ilc`, 5000 ms, SIGKILL, detached, stdin/stderr ignored, stdout piped. The injected exec wrapper only adds the synthetic environment or dispatches that same shell invocation inside the recorded immutable Docker image. A second diagnostic invocation pipes stderr; stdout was verified byte-identical to the production proof invocation in every case. JSON escapes preserve control characters and whitespace.

All profile contents, commands, shell/package versions, image IDs, startup logs, raw stdout/stderr, statuses, and real-reader parsed results follow.
