I'm a bit confused about what the [docs mean regarding standalone markdown files](https://doc.rust-lang.org/book/documentation.html#other-documentation) if they're not referring to this feature. Am I missing something obvious?

``` ArgumentInvalid: LayoutError: ValueScalingFailed { ratio: 1.334448160535117, basis: -100, invalid_result: -133.44481605351172 } at imageflow_core\src\flow\nodes\command_string.rs:96:61 https://github.com/imazen/imageflow/blob/70945c00267a99d678fb0d53e675dc7827e12fe2/imageflow_core/src/flow/nodes/command_string.rs#L96 imageflow_core\src\flow\execution_engine.rs:294:29 https://github.com/imazen/imageflow/blob/70945c00267a99d678fb0d53e675dc7827e12fe2/imageflow_core/src/flow/execution_engine.rs#L294 imageflow_core\src\context.rs:419:59 https://github.com/imazen/imageflow/blob/70945c00267a99d678fb0d53e675dc7827e12fe2/imageflow_core/src/context.rs#L419 imageflow_core\src\context_methods.rs:50:68 https://github.com/imazen/imageflow/blob/70945c00267a99d678fb0d53e675dc7827e12fe2/imageflow_core/src/context_methods.rs#L50 Active node: NodeDebugInfo { stable_id: 1, params: Json( CommandString...

Fixed in latest.

I'm experiencing this on Github Actions OS X runners: https://github.com/imazen/imageflow-dotnet-server/runs/7983577554?check_suite_focus=true#step:11:24 using this workflow: https://github.com/imazen/imageflow-dotnet-server/blob/ca26aa3197887c1520cb32d8ae36647786282f7c/.github/workflows/dotnet-core.yml MSBuild version 17.3.0+92e077650 for .NET dotnet version 6.0.400 and 3.1.422

I have tried `false` per https://github.com/dotnet/sdk/issues/22201 with no improvement.

I think this might very well be related. I'm going to try dotnet build --maxcpucount:1 https://github.com/dotnet/sdk/issues/22201#issuecomment-1259608904

I'll let you know if a failure recurs, but I think you're right about it being a concurrency issue.

Also reported here: https://github.com/dotnet/sdk/issues/27320

After reviewing things, I noticed tilt uses string keys instead of symbols. I also couldn't think of a reason to justify needing fallback capabilities, although that doesn't mean there isn't...
