+- **A real bug in `pgo.yml`'s BOLT stage, found in PR review**: re-invoking the whole
+  `scripts/pgo/run.sh` between `cargo pgo bolt build` and `cargo pgo bolt optimize` ran a
+  separate, non-BOLT PGO cycle that never fed BOLT's profile data and could clobber the
+  bolt-instrumented binary with an unrelated plain-PGO one. Fixed per `cargo-pgo`'s own
+  documented BOLT+PGO combined workflow: `--with-pgo` on both `cargo pgo bolt build` and
+  `cargo pgo bolt optimize`, with the erroneous `run.sh` re-invocation removed. Real BOLT profile
+  gathering (running the actual GUI frontend binary against a workload) stays out of scope —
+  this project's frontend has no headless CLI mode — so the fix deliberately uses `cargo-pgo`'s
+  own documented profile-less BOLT fallback instead.
