 ## Integration candidate, 2026-10-31
 
 This owned integration branch combines preserved source `e2b35be76f` with
-master `f2db909393`. The original preservation branch and its historical results
+master `8bcc5a01ed`. The original preservation branch and its historical results
 remain unchanged. No historical pass transfers to this composed source.
 The frozen 244-case OpenCode catalog keeps its historical IDs and DeepSeek 1017
 model. The two shipped subscription aliases and the separate TestOps backlog cell
 remain selectable alongside it; they do not change the frozen denominator.
 The standalone aliases retain the current shipped 120-second turn limit.
 Catalog phase and attempt budgets remain separately declared by their fixtures.

+The integration compatibility checks distinguish the 244 historical cells from
+the three shipped aliases. Fixtures implement current run-observation and
+conversation-link custody contracts. The standalone flows keep shipped timeout
+behavior; catalog-native setup still verifies its separately declared policy.
+Synthetic public-schema tests hash their copied synthetic inputs, while the
+production frozen source manifest and all private-value rejection checks remain
+unchanged. No SDK runtime qualification follows from those synthetic tests.
