+# Support Tiers
+
+## Purpose
+
+This document keeps the revival effort honest about what must work first, what can wait for parity, and what belongs to later modernization.
+
+## Required For Core Revive
+
+- hosted replacement cloud reachable through legacy Jibo host routing
+- token, account, robot, and session bootstrap flows needed for startup
+- basic WebSocket connectivity for listen and proactive channels
+- minimal turn handling and a normalized `ResponsePlan` path
+- Azure deployment foundation
+- Azure SQL-backed persistence design
+- bootstrap documentation for router, DNS, RCM, TLS patching, and smoke tests
+
+## Optional For Parity
+
+- broader `X-Amz-Target` family coverage
+- richer media management
+- more complete key and sharing flows
+- higher-fidelity update metadata behavior
+- more native-skill bridging and expression parity
+- more complete per-version device behavior mapping
+
+## Future Modernization
+
+- OTA-first recovery for non-technical owners
+- paid hosted plans, subscriptions, and donation flows
+- deeper on-device modernization
+- richer runtime orchestration and AI providers
+- community plugin or skill ecosystem
+- OS, bridge, and firmware modernization beyond hosted-cloud recovery
