 | [Dynamic Model Catalog](dynamic-model-catalog-plan.md)                                             | Implemented | Validated pi.dev overlays, offline `0600` cache hydration, scoped setup refresh, four-hour launch refresh, force refresh, Pi metadata fallback, and Mac/iOS projection ship on pinned Pi 0.80.10. |
 | [Generation Progress Notes](generation-progress-notes-plan.md)                                     | Planned | No implementation yet.                                                                                                                                                                                                    |
+| [iOS Remote Caching Strategy](ios-remote-caching-strategy-plan.md)                                 | Planned | Research complete: Workspace `GET /chats` still hydrates every full transcript, iOS Workspace home is not cache-first, connecting overlays hide warm cache, and Bot inbox already is cache-first. Implementation starts with chat summaries plus session/workspace snapshots; collection 304s and model-catalog reuse follow. Do not add a mega `/mobile-bootstrap` unless traces say handshake RTT dominates. |
 | [Onboarding Authentication and Provider Validation](onboarding-auth-and-provider-validation-plan.md) | Active | Codex onboarding now uses its dedicated auth surface, completion state is main-owned, and hosted/local endpoint readiness validation is under focused verification and fresh review. |
 | [Performance, Stability, Battery, and Efficiency](performance-stability-efficiency-plan.md)        | Planned | Whole-app source audit is complete; implementation starts with instrumentation, durable state, and hard memory bounds.                                                                                                    |
 | [Pi Provider Integration](pi-provider-integration-plan.md)                                         | Partial | Pi built-ins, stores, auth, native routing, custom provider composition, canonical assistant provenance, and voice credential lookup ship; scalable UX and rollout cleanup remain.                                        |
