+# Builds a markdown section documenting the pinned CodeQL CLI version and
+# comparing every direct `codeql/*` dependency declared in each language's
+# `src/qlpack.yml` AND `lib/qlpack.yml` (e.g. `codeql/<lang>-all`, and
+# `codeql/<lang>-queries` for the languages that also depend on the standard
+# queries pack) against the canonical version github/codeql itself bundles
+# for that CLI release.
+#
+# Both `src` and `lib` are checked independently, not just `src`. Each pack
+# directory has its own `codeql-pack.lock.yml`, resolved separately by
+# `codeql pack upgrade <dir>` - the `codeql/<lang>-all: '*'` dependency each
+# of them declares can therefore drift out of sync with each other (e.g. if
+# someone runs `codeql pack upgrade <lang>/src` alone to fix a compile error
+# after a CLI bump, and forgets `<lang>/lib`). Nothing in this repo enforces
+# they stay identical, so both are treated as independent sources of truth
+# here rather than assuming one implies the other.
+# `ext`/`ext-library-sources` packs are deliberately NOT checked: they pin
+# their target via `extensionTargets:`, not `dependencies:`, which CodeQL
+# does not resolve into a version-locked `codeql-pack.lock.yml` entry (their
+# lock files have an empty `dependencies: {}`), so there is no locked version
+# to compare there.
+#
+# Dependencies are discovered dynamically from each qlpack.yml (not
+# hardcoded) so this stays correct if a language adds/drops a direct
+# `codeql/*` dependency.
+#
+# Both the "our locked" and "upstream" version cells link directly to the
+# exact file+line that pins that version, at the exact commit (ours) or CLI
+# tag (upstream) being compared - so a maintainer can verify the claim with
+# one click instead of trusting the table.
+#
+# This exists because CI's "codeql pack install" step is non-resolving: it
+# only installs whatever is already pinned in the checked-in lock file, it
+# never re-resolves/upgrades versions. If a maintainer bumps .codeqlversion
+# but forgets to run `codeql pack upgrade` for one of a language's pack
+# directories, that directory's lock file silently stays on a stale version
+# forever, and CI stays green. This table is a machine-checkable tripwire for
+# that drift - see CONTRIBUTING.md's "Updating the pinned CodeQL CLI/library
+# version" section.
