Homebrew installation of 0.56.0 is killed while generating shell completions

[sadysnaat]

Description

Installing Orchard 0.56.0 through the openai/tools Homebrew tap fails while Homebrew generates Bash completions. The Orchard process is terminated with SIGKILL and the formula is not installed.

Environment

• macOS 26.5 (Darwin 25.5.0)
• Apple Silicon (arm64)
• Homebrew prefix: /opt/homebrew
• Orchard formula: openai/tools/orchard 0.56.0

Steps to reproduce

brew install openai/tools/orchard

Observed output

Error: Failure while executing; `\{"SHELL" => "bash"\} /opt/homebrew/Cellar/orchard/0.56.0/bin/orchard completion bash` was terminated by uncaught signal KILL.

Running the downloaded 0.56.0 ARM64 binary directly also exits with status 137 for commands such as --help, while the completion command produces no output. As an additional data point, codesign --verify --verbose=4 orchard reports that the binary is valid on disk but does not satisfy its designated requirement.

The 0.55.0 ARM64 release does not show the same behavior on this machine.

Since we switched from Cirrus CI to GitHub Actions (commit 461af8d), the macOS binary is no longer properly notarized. The binary is signed with Hardened Runtime, but the notarization step fails because GoReleaser by default tries to notarize the raw binary itself, while Apple's notary service only accepts .zip, .dmg, or .pkg archives. As a result, no notarization ticket is attached, and macOS kills the process on launch (zsh: killed ...).
