   - this matters because `previous_filters.organization` is now aligned with the same continuity authority story that already drives route, living-chat, and data-scope, instead of keeping one more hot-path-only merge order inside transition glue;
   - targeted `assistantContinuityPolicy` and `assistantTransitionPolicy` suites are green after the move, with direct helper coverage for organization precedence and for preserving an already grounded organization value;
   - a fresh live rerun of `address_truth_harness_phase12_wider_saved_session_pool` on `2026-04-19` remained semantically stable and again failed only on the already-known date-sensitive `today` expectations, not on the new shared organization carryover authority.
+- the next continuity-authority pass now centralizes displayed-entity retargeting and removes another hidden duplicate owner from the transition hot path:
+  - continuity now owns `resolveDisplayedEntityFollowupRetarget(...)`, so `displayedEntityTargetIntent` and the companion carryover mutation for displayed counterparty / contract mentions are produced by one shared helper instead of being split between a local retarget branch and a separate transition mutation block;
+  - the shared retarget contract is now explicitly UTF-8-safe, which matters because a broken regex encoding in the first extraction attempt silently collapsed short phrases like `покажи договоры по СВК` back into stale previous-intent carryover;
+  - `assistantTransitionPolicy` no longer keeps a second local `resolveDisplayedEntityRetargetIntent(...)` owner beside the shared continuity helper, which reduces another chance that future follow-up fixes land in dead code or diverge between route retarget and anchor hydration;
+  - targeted `assistantContinuityPolicy` and `assistantTransitionPolicy` suites are green after the move, and a fresh live rerun of `address_truth_harness_phase11_manual_followup_meta_quality` on `2026-04-19` is accepted `10/10`, including the short displayed-counterparty retarget step.
