# CodeQL code scanning, advanced setup.
#
# This repository uses advanced setup (this workflow) rather than default setup
# because default setup does not run on pull requests from forks, which leaves
# external contributions permanently blocked by the `code_scanning` rule in the
# `main` ruleset. See https://github.com/github/codeql/issues/19698.
#
# Default setup and advanced setup are mutually exclusive: while default setup is
# enabled, uploads from this workflow are rejected with "CodeQL analyses from
# advanced configurations cannot be processed when the default setup is enabled".
#
# The `pull_request` trigger is used deliberately, not `pull_request_target`.
# Fork pull requests receive a read-only GITHUB_TOKEN, but github/codeql-action
# uploads its SARIF through an endpoint that is exempt from the usual
# `security-events: write` requirement, so analysis of fork pull requests works
# without granting write tokens to untrusted code.
