+# Bash replacement for the prior Python implementation; Python is wholly
+# outlawed estate-wide (hyperpolymath/standards [Language Policy]) and the
+# governance / Language / package anti-pattern policy gate fails on any
+# in-tree `.py` file. This validator does the same three checks the Python
+# version did, purely via POSIX text tools — no TOML parser dependency.
+#
+# Checks:
+#   1. [project] section has a non-empty `name`
+#   2. At least one `[[functions]]` table is declared
+#   3. Each `[[functions]]` table has a non-empty `name` and `source`
