* perf(timeline): resume cached history from its exact range
Warm launches were repainting cached history and then downloading the same bounded tail to rediscover that nothing changed. Persist synchronization authority only when the complete current canonical window can be encoded losslessly; otherwise retain the existing display-only fallback.
* test(timeline): hide replica setup behind E2E helper
* fix(timeline): bound persisted resume overflow
* test(timeline): cover workspace eviction catch-up order
* test(timeline): read persisted range from IndexedDB
* feat(sync): restore host directories before reconnect
Persist complete project, workspace, and active-agent replicas so every registered host can paint immediately, including offline hosts. Reconcile those replicas through monotonic per-entity cursors on the existing directory RPCs without retaining an event journal.
* fix(sync): preserve active turn identity during catch-up
Own Agent-to-wire projection beside the existing snapshot normalizer so replica persistence does not reach through directory-sync internals. This also keeps identified active turns intact when unchanged agents are folded into an incremental directory response.
* test(e2e): inspect the real IndexedDB replica
Keep cache setup, reload, and hydration coverage on the production browser storage backend after the replica moved off localStorage. Measure writes at the actual IndexedDB put boundary as well.
* fix warm reconnect cache paths
* feat(sync): persist project icons and deepen directory sync
* fix(sync): preserve project update order
* fix(cache): preserve validated replica persistence
* fix(sync): retain cached agents during catch-up
