Area: mobieusKnow (audit p6) · Surface: mobieusKnow navbar entry + breadcrumbs on every desktop know page · Dimension: law-2-nav-orphan · Severity: major
The safe landing is bare /know (routes.php:583 KnowledgeController@index), which renders a directory listing when no index page exists. But NOTHING in the desktop UI links to bare /know — every link goes to /know/index. If a moderator deletes the index page (allowed, no guard), or the non-fatal seed ever fails, the entire desktop wiki becomes unreachable from the nav: the navbar Know link 404s, every breadcrumb 404s, and deletePage redirects the mod straight into a 404. Mobile templates correctly link to bare /know (mobile/knowledge/show.php:30), which exposes the inconsistency.
Evidence
navbar.php:501 <a href="/know/index" class="nav-link">…Know</a>. Breadcrumbs in show.php:92, history.php:31, editor.php:31/40/214, revision.php:101 all point to /know/index. Route table has NO /know/index route; /know/{slug} (routes.php:588) matches slug='index', and KnowledgeController::show() calls abortNotFound() when the page is missing (KnowledgeController.php:51-53). deletePage() has no guard against deleting the index slug (KnowledgeController.php:538-555) and even redirects to /know/index after deleting (line 554). The seed that creates the index page is non-fatal (provision-tenant.sh:1401 'php "$KNOW_SEED" ... || warn').
Suggested fix. Point the navbar and all breadcrumbs at bare /know (let the controller redirect to /know/index when an index page exists, fall back to the listing otherwise), and/or block deletion of the slug 'index' in deletePage(). At minimum change deletePage's post-delete redirect to /know.
