§10 review pass: address the architecture + product reviewers (todo §10); hide the gated Dashboard nav node from anonymous visitors in buildPluginChrome (a no-permission link to /dashboard only dead-ended them at /login) and dedup it into a shared DASHBOARD_NAV (admin-nav.ts, reused by chrome + adminNav). New chrome.signInHref bakes the current page in as return_to for the shell's anonymous Sign-in link (shell.ejs + reference overview.ejs), mirrored as optional ShellModel.signInHref so the typed builder is complete. ctx.chrome is now a lazy, memoized getter (context.ts chrome option = a factory) so a json/redirect handler or the public "/" with a standalone home never composes the global menu — app.ts passes the app-level memoized factory at every site. Default /dashboard prints a "Starter dashboard" note framing the mock-data home as a replaceable demo (signals its inert affordances); stale "until §4" comments fixed. RESERVED_PLUGIN_IDS drift-guard test derives the built-in segments from AUTH_FLOWS + ADMIN_*_BASE + host literals (home stays deliberately unreserved). Refreshed the stale plugin-contract status blurb and documented the chrome.*→partials/shell mapping. Reviewers: architecture + product APPROVE (no addressable findings remain), stability APPROVE (no Critical/High/Medium). typecheck + 356 units + visual(10) + full-flow(7) E2E green.
