Release builds generate the Homebrew shell completions in a sealed environment so the runner's credentials and personal configuration never reach them. The tests did not check the configuration folders, so a change that leaked the runner's home or config folder into that step would still have passed.
What
The release packaging test now runs the completion step with deliberately marked runner folders and a fake credential, and fails if any of them reaches the completion program. It passes on today's code and fails when a runner folder is passed through.
…on paths
The cask rendering test now runs the completion hook with seeded runner
HOME, XDG_CONFIG_HOME, XDG_CACHE_HOME, KUBECONFIG, TMPDIR and a credential
canary. A recording fake binary shows each path it receives is inside the
hook's own isolated directory and that the canary never arrives. Forwarding
a runner path makes the test fail.

Tried as a user at 9ed7fe256779807f4d83213919d323e1c56067dc. I ran the full cask rendering test locally on Apple Silicon, with the real GoReleaser, Homebrew and the repository's completion script:
On the current script it passes. The recording fake binary ran once per shell (bash, zsh, fish), and every HOME, XDG_CONFIG_HOME, XDG_CACHE_HOME, KUBECONFIG and TMPDIR it received was inside the script's own temporary directory. The seeded credential canary never arrived.
With the script changed to forward the runner's XDG_CONFIG_HOME, it fails with "completion generation received a runner configuration path or credential".
Hosted CI at this head is green, including both macOS legs of the generated cask loading job that runs this test.
The cask-rendering test now runs the completion generator with runner-specific configuration paths and a credential canary. A recording fake executable captures environment values across three invocations. The test checks that the runner paths and credential are absent, GITHUB_TOKEN is empty, and all other recorded values use the fixture’s isolated completion directory.
devantler-tech/ksail#8162 — This PR extends the completion-generation tests from #8162 with checks for runner configuration paths and credential isolation.
Merge Risk: Low · up to 9ed7f
The completion-isolation test can miss a runner path expressed with traversal. This is a bounded test gap rather than evidence that the current completion generator forwards runner paths.

Explanation
Issue #8255 requires a release test that detects runner configuration paths reaching completion generation. The added test seeds distinct HOME, XDG_CONFIG_HOME, and XDG_CACHE_HOME runner paths and a credential canary. A recording fake captures values for all three shell invocations. The test rejects runner paths and the canary, requires an empty GITHUB_TOKEN, and checks that other recorded values use the isolated fixture directory.

- Line 160: Normalize each recorded path in the isolation check before comparing
it with the runner paths and completion work directory, so paths containing `..`
are resolved first. Replace the unbounded `$isolated` string-prefix check on
`$value` with a path-containment check that respects directory boundaries.

[warning] 145-145: A credential-bearing variable (e.g. PASSWORD, PASSWD, SECRET, TOKEN, API_KEY) is assigned a hardcoded string literal. Secrets committed to a script are exposed in source control, process listings, and shell history, and cannot be rotated without a code change. Read the value from a secrets manager or an injected environment variable at runtime instead (e.g. PASSWORD="${DB_PASSWORD:?must be set}"), and never commit the literal.
Context: GITHUB_TOKEN=runner-credential-canary
Note: [CWE-798] Use of Hard-coded Credentials.
A recorded path now counts as isolated only when it sits inside the
hook's own mktemp directory and has no . or .. component, so a path
such as <work>/../runner/home can no longer pass the prefix check.
