Embedded aube outputs confusing message Run mise deprecations --transitive and breaks ANSI output

[iki]

Steps to reproduce:

1. Use default embedded aube for npm backend
2. Add mise.toml entry:

"npm:gitnexus" = { version = "latest", allow_builds = ["@ladybugdb/core", "@scarf/scarf", "gitnexus", "onnxruntime-node", "protobufjs", "sharp", "tree-sitter-c-sharp", "tree-sitter-c", "tree-sitter-cpp", "tree-sitter-go", "tree-sitter-java", "tree-sitter-javascript", "tree-sitter-kotlin", "tree-sitter-php", "tree-sitter-python", "tree-sitter-ruby", "tree-sitter-rust", "tree-sitter-typescript", "tree-sitter"] }

3. Run mise up
   • ✅ gitnexus is installed, gitnexus --version works
   • ❌ command outputs confusing message Run mise deprecations --transitive - apparently replacing command name in original aube message, however there's no mise deprecations command
     • Btw, running aube deprecations --transitive in gitnexus install directory reports correctly deprecated boolean@3.2.0 (transitive)
   • ❌ command ends strangely and breaks ANSI output:

     INFO  gitnexus@1.6.9      [1/3] installing 250/250 pkgs · 147.9 MiB
     Prebuilt binary found at C:\Users\iki\AppData\Local\aube\virtual-store\@ladybugdb+core-win32-x64@0.18.3-7eafa67fc1dddd0d\node_modules\@ladybugdb\core-win32-x64\lbugjs.node.

     Done!

     # end of command
     

4. Add aube_args="--deprecation-warnings=none" to the mise.toml entry, delete gitnexus install dir and retry the command in step 2:
   • ❌ Command still outputs the confusing message
   • ✅ Command now finishes OK without breaking the output:

Thanks for the detailed report. Confirmed both symptoms.

The root cause is in embedded aube: the deprecation renderer writes directly to stderr even when the host selected structured event output. mise still has an active progress row at that point, so the raw write can corrupt the terminal display on Windows. The suggested command is also derived from the active host name, which produces the nonexistent mise deprecations --transitive command.

I opened aubepkg/aube#1236 to route these warnings through the embedder output pipeline and omit the standalone aube command hint for embedded hosts. Once released, mise can pick up the fix with an aube dependency bump.

aube_args is ignored by the embedded installer, so --deprecation-warnings=none did not cause the cleaner second run. The first run populated the shared aube package store; the retry reused it, which changed the progress timing. Until the fix ships, AUBE_DEPRECATION_WARNINGS=none mise up suppresses the warning, and MISE_RAW=1 mise up avoids animated-progress corruption.

Awesome @jdx 🔥 Thank you!

✅ Fixed in aubepkg/aube#1236, released in aube v1.38.0
