   - more saved-session and multi-trajectory replay breadth;
   - less duplicated state reconstruction in route / transition / living-chat glue;
   - controlled expansion only after those broader proofs stay green.
+- the next authority-convergence pass now also removes one more duplicate scope builder at the very start of the turn:
+  - `assistantOrganizationScopeRuntimeAdapter` no longer reconstructs `knownOrganizations / selectedOrganization / activeOrganization` only from its own local history helpers;
+  - the same session-scope bootstrap now consumes the shared continuity-backed organization authority first and only then falls back to older helper outputs and navigation-state overrides;
+  - this matters because route, living-chat, data-scope, and early session-scope bootstrap are now closer to the same organization merge order instead of keeping a separate pre-route branch with its own drift risk;
+  - targeted tests now explicitly protect the case where assistant-side continuity authority is present in prior assistant debug even when legacy history helpers are empty;
+  - live replay `address_truth_harness_phase12_wider_saved_session_pool_live_20260418_rerun4` remains accepted `20/20`, which is the critical proof that this authority convergence did not reopen the wider saved-session path.
