+The build itself includes an additional guard: `_plugins/nav-integrity-check.rb` runs during the GENERATE phase and aborts the build if any nav-visible page has a `parent:` (or `parent:` + `grand_parent:`) that does not resolve to exactly one page in the nav tree. It catches two failure modes:

+- **Ambiguity** — multiple pages share the title declared in `parent:` and `grand_parent:` is either absent or insufficient to disambiguate. The page would silently appear under every matching parent.
+- **Orphan** — no page has the title declared in `parent:`. The page would silently disappear from the navigation sidebar.

+# Package Management
 
 In twinBASIC, a *package* is a collection of components that you can reference from another twinBASIC project.  The components can be modules, classes or interfaces.
 
+twinBASIC comes complete with a package manager service called TWINSERV[^1], allowing you to share and distribute TWINPACK packages to other twinBASIC developers.
+
 A twinBASIC package is distributed as a TWINPACK file that contains everything needed by the components in that package.  A project that references a TWINPACK package, imports the whole package into the file system of the root project, resulting in no external dependencies.
 
 With TWINPACK packages you group common components together into their own namespace whilst allowing for convenient code reuse without any of the problems often associated with using external DLL libraries.
 
-twinBASIC comes complete with a package manager service called TWINSERV, allowing you to share and distribute TWINPACK packages to other twinBASIC developers.
+Please be aware that TWINPACK files currently contain the full source code of your packaged components.  It is planned that we will in future allow for creating binary (compiled) TWINPACK files for developers that hold an Ultimate edition licence of twinBASIC.

+# frozen_string_literal: true
+
+# Fails the Jekyll build when any nav-visible page has a `parent:` (and
+# optionally `grand_parent:`) that does not uniquely identify its
+# position in the navigation tree.
+#
+# === Background ===
+#
+# just-the-docs builds its nav tree by matching each page's `parent:`
+# against other pages' `title:`. When multiple pages share the same
+# title, the theme attaches the child under every matching parent —
+# unless `grand_parent:` is declared to disambiguate. This duplication
+# is silent: no warning is emitted, and the child simply shows up in
+# multiple places in the nav (or, worse, only under the wrong parent
+# due to render-order-dependent first-occurrence logic).
+#
+# This generator detects and reports these ambiguities at build time so
+# they can be fixed before deployment.
+#
+# === Logic ===
+#
+# For each nav-visible page P that declares `parent: X`:
+#
+#   1. Find all nav-visible pages whose `title` == X.
+#   2. If only one candidate exists → unambiguous, pass.
+#   3. If multiple candidates exist:
+#      a. If P has no `grand_parent:` → AMBIGUOUS.
+#      b. If P declares `grand_parent: G` → keep only candidates whose
+#         own `parent` == G.
+#         - If exactly one remains → disambiguated, pass.
+#         - If multiple remain → STILL AMBIGUOUS.
+#         - If zero remain → orphan (no valid parent); reported as a
+#           separate diagnostic.
+#
+# === Priority ===
+#
+# Runs at :high priority so it executes before nav-tree-precompute and
+# nav-levels-precompute, catching problems before they propagate.
