P85 taught the profiler about userspace ELF symbols. The input is still
the P84 shell workload, but now samples between shell_start and
file_ok are resolved against BusyBox’s busybox_unstripped sidecar.

shell_start | 159,733,543 |
file_ok | 239,533,859 |
Top profile rows:
| bucket | function | samples | pct |

| kernel | memset | 3,347 | 4.29% |
| kernel | vruntime_eligible | 2,954 | 3.79% |

| busybox | __fwritex | 1,763 | 2.26% |
Status: PASS for userspace symbolization and site data staging.
True stack unwinding is NOT RUN. Per-PID symbol identity is PARTIAL
because the sample stream does not include the current process.
