name: CodeQL

# Advanced (workflow-based) CodeQL setup — replaces the UI "default setup".
#
# Why advanced setup: this is a five-module Go workspace (forge-core, forge-cli,
# forge-plugins, forge-skills, forge-ui). Default setup's Go autobuild does not
# reliably compile all five modules, so the package set it analyzes varies run
# to run. When the analysis on `main` (the baseline) covers a different set than
# the analysis on a PR head, GitHub's diff reports pre-existing alerts in
# untouched files as "new alerts in code changed by this pull request" — which
# is what was blocking PRs that never touched the tool layer.
#
# This workflow builds all five modules explicitly (mirroring ci.yaml), so every
# run — the `main` baseline and every PR — analyzes the identical, complete
# package set. The PR diff then only flags alerts a PR actually introduces.
#
# NOTE: default setup must be turned off in repo Settings → Code security →
# "CodeQL analysis" (switch to Advanced) before this runs, or GitHub rejects the
# results upload as conflicting with default setup.
