+- **F1 Model Activity restored.** Session create/resume now preserves configured/persisted
+  thinking instead of forcing `off`. Pi's nested `thinking_delta` is bridged to a dedicated
+  named SSE `activity_delta`; EventSource subscribes to that name and the panel keeps it separate
+  from final assistant text. Reasoning remains in-memory and is not persisted to session artifacts.
+- **F3 rewrite confirmation remains bypassed.** `rewrite_question` records approval and advances
+  automatically without a reviewer widget. The repeated prompt came from old running containers:
+  images had been rebuilt but services had not been recreated.
+- **Join review is read-only and complete-set safe.** Join-only proposals render informational
+  cards with only `Continue` and `Other — specify`. Continue requires the exact complete id set;
+  all joins are persisted together by `decision add-join-set`, using an atomic ledger replacement
+  under a per-session cross-process writer lock. Other persists none of the rejected proposal.
+- **CTE presentation fixed.** F6 CTE cards now structure purpose, rationale, tables, filters, keys,
+  and output columns with responsive wrapping/alignment. The Horizontal/Vertical switch is hidden
+  for a single SQL block (the per-CTE view), because it only affects multi-block layouts.
+- **Latest render failure diagnosed and hardened.** Session
+  `2026-07-14-115847-estrai-i-pazienti-che-hanno-fatto-un-abl` sent an object in
+  `open_questions`, which React cannot render as a child. The v2 gate now enforces
+  `open_questions?: string[]`; the frontend also safely normalizes legacy malformed payloads.
+- **Verification/deploy:** Python harness 798 passed / 5 L2 deselected; gate JS 126; backend 143;
+  frontend 250; TypeScript/build gates green. Compose rebuilt and force-recreated both services.
