The 2026-07-27 intent-named operations note still declared that a
continuable provider requires `flush()` to resolve `true` at its final
result boundary and maps `false`/rejection to `DURABILITY_FAILED`. The
activation-based record (2026-07-28-continuable-subagent-conversations)
superseded that contract: the manager awaits the final flush as a
best-effort barrier and deliberately ignores the boolean, because listener
participation cannot identify a persistence backend.
Active notes are the current source of truth — sync both sides of the
bilingual pair by marking the old clause superseded with a link to the
record that replaced it.
