- The event name is misspelled, which makes this security-sensitive explanation harder to match to the actual trigger above.
# Note that "pull_requqest_target" events are always triggered even
.github/workflows/base-test.yml:18
- Use the plural determiner with “precautions.”
# Note also that this precautions might be overkill because a fork
.github/workflows/base-test.yml:21
- “Practice” is the noun required in this phrase.

In @.github/workflows/base-test.yml:
- Around line 52-55: Update the checkout steps in
.github/workflows/base-test.yml:52-55, .github/workflows/secrets_test.yml:33-36,
.github/workflows/timeout-test.yml:33-36, and
.github/workflows/variables_test.yml:33-36 so privileged pull_request_target
jobs use the trusted base revision rather than
github.event.pull_request.head.sha; pass the pull request SHA only as data to
the Testing Farm action. Ensure the local uses: ./ execution and privileged
status/comment operations cannot run pull request dist/main.js code.
- Around line 35-42: Replace the mutable actions-cool/check-user-permission@v2
reference with the same reviewed full commit SHA in all four workflows:
.github/workflows/base-test.yml lines 35-42, .github/workflows/secrets_test.yml

Do not execute the pull request checkout in these privileged pull_request_target jobs. All four workflows check out github.event.pull_request.head.sha and then run uses: ./, which executes the pull request’s dist/main.js with TF_PUBLIC_API_KEY, GITHUB_TOKEN, and write permissions. The permission check does not make pull request code trusted. Run the action from the trusted base revision, and pass the pull request SHA to Testing Farm as data. Separate untrusted processing from privileged status and comment operations.
