What common plan can a diverse ecosystem set up and
Even for a single species, like us, you're dealing
with 7 gigamonkeys. There will be never complete

A diverse culture consists of not just inviduals
(like us) but of multiple species. Those who don't
put a high value into self-reproduction (the main
driver for transforming inanimate well-insolated
atoms into self) self-select into invisibility.
The other kind become a fat blip on your instrument

Do you speak for 7 gigamonkeys? Can you be blamed for
every shenanigan they do? Are you responsible for what
the Earth ecosystem does? What about invasive species?

They're not probes. They're animals. Results of a long
series of selection steps, with the fitness function
only selecting for one thing: expandability.
Imagine a tube of sterial medium a lightyear wide.
Inoculate it with something at one end, and be it
even a single E. coli colony. Wait (a long time).
What will emerge on the other end? It will definitely
be not E. coli.

They're not wiping out anything. Not deliberately.
They just eat and self-reproduce.

The most powerful civilization can't travel faster
than c. The question is of logistics, not elegance
The only chance you have is when you detect that
you've produced a contamination wavefront that will
eat the universe is to build extremely lightweight
extremely relativistic craft that overtakes your
pioneers in flight, colonizes every stellar system
they can (so they're at least as expansive, only not
visible) with immune systems powerful enough to
detect pioneers, and keep their population under
control (ideally, at zero).
Can this be done? No idea.

The humanity has done some pretty repulsive things.

The pioneers occupy an extremely narrow niche, which results
in convergent evolution, whatever the point of origin. They
assume an essentially pristine stellar system. Anything else
they can't metabolize.
Imagine a fresh volcanic island, which happens to be colonized
by roughly the same pioneer plants at the same time. What happens
when the two plant colonies meet in the middle? Not much.
And what happens when other species arrive? Why, a succession
of pioneer species. Eventually, you'll get a nice tropical island
going. A canoe with a Polynesian family from a neighbor island
arrives, and sets up shop there.
