3- **Rerun this before trusting `packages/replay` after any change to the core**
4  (a `jgenesis` subtree pull, a new `snes-core` feature, a toolchain move that
5  touches float maths). A diverged core makes seek, rebuild and the disk cap
6  silently produce a wrong machine; this probe is the only thing that says so.
7- **Measure here before and after changing a replay knob** (`RECORD_EVERY`,
8  the tier retention constants, the storage cap): its numbers are what those
9  constants were sized by.
10- It starts a real `zbanks::Bot`, so it is one bot per process like
11  everything else; do not add a second pass that starts another bot.
12- Output is `run/replay-probe/`, removed and recreated on every run. Never
13  point it at anything that matters.
