Implement phased modernization infrastructure for transitioning from multi-page legacy routing to SPA portal-shell architecture, plus post-delivery hardening fixes for policy loading, fallback consistency, and governance drift detection. Key changes: - Add route contract enrichment with scope/visibility/compatibility policies - Canonical 302 redirects from legacy direct-entry to /portal-shell/ routes - Asset readiness enforcement and runtime fallback retirement for in-scope routes - Shared feature-flag helpers (env > config > default) replacing duplicated _to_bool - Defensive copy for lru_cached policy payloads preventing mutation corruption - Unified retired-fallback response helper across app and blueprint routes - Frontend/backend route-contract cross-validation in governance gates - Shell CSS token fallback values for routes rendered outside shell scope - Local-safe .env.example defaults with production recommendation comments - Legacy contract fallback warning logging and single-hop redirect optimization Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
