Easy way to test this just by dumping and diffing the tracing logs

Option: require `defer_tick()` on all "backwards" edges (higher -> lower stratum number)

in general the bug is only one case, where the cycle thru negation doesn't happen to line up with where we check for missing defer_tick

Would (probably) be no longer relevant after flo loop context semantics #1500

* Closures in maps vs closures in demux * Can we (or why can't we) make something to combine demux/tee and unions to eliminate diamonds? * How should we think...

#330

Termination detection (#928)

`cargo install cargo-insta` `cargo insta test` or `cargo test --all-targets --no-fail-fast` `cargo insta review`

Closing in favor of #1118
