Added

• Place checks. Two places with one id are an error — they draw one box in every view, and the map stops saying where the user is. A place with no affordances is a gap unless it holds a subplace, and a subplace whose parent the map never declares is an error: a widget inside a place that does not exist renders as a screen of its own.
• A test that the standalone alternatives recipes have not drifted. The interface-alternatives / architecture-alternatives recipes are copies of the canonical recipes' first three tasks (they remain as Explore/standalone entry points). The test pins the copy to the original, so editing the gate's pipeline cannot leave the standalone pipeline running the old shape.

Fixed

• Subplaces are drawn inside their place. P2.1 was emitted as a sibling of P2, which says the widget is a separate screen and that the user leaves P2 to reach it. The serializer nests it, and the markdown view gained a Within column (and a (within P2) heading) so the containment survives without the picture.
• Two place references that differ only by punctuation merged into one node. Node ids rewrote every punctuation character to _, so _a-b and _a_b — two different references — became one Mermaid node. The rewrite is injective now (_<hex>_).
• The renderer ignored unknown flags. --emmit-markdown exited 0 and wrote nothing, which reads exactly like a successful run. A run with flags but no command did the same, so a scripted --check could report success without checking. Both are usage errors now; --with-diagram without --emit-markdown is refused instead of ignored.
• The markdown frontmatter broke on a colon in the interface id. Values are quoted; A: the "quiet" one is a legal id and an illegal unquoted YAML scalar.
• The playbooks pointed at a script the product repo does not contain. The check and render commands now name <stelow-checkout>, and the reference says what that is, that install.sh does not install it, and that a missing script means "unchecked", never "clean".
• state-contract.md claimed only Markdown is registered. stelow advance registers every file in the workflow directory (kind: artifact for anything that is not .md), which is what makes breadboard.md, .mmd and .html legal outputs.
