+### Patch Changes
+
+- [#1788](https://github.com/cloudflare/agents/pull/1788) [`3b2af54`](https://github.com/cloudflare/agents/commit/3b2af5444af5002cd54fd493452e03c721d31999) Thanks [@threepointone](https://github.com/threepointone)! - Converge recovery forward-progress crediting between `AIChatAgent` and `Think`.
+
+  Both hosts now credit the recovery no-progress counter through one shared, host-agnostic rule (`shouldCreditStreamProgress`): a progress milestone (a started text/reasoning segment or a settled tool input/output) credits unconditionally, and mid-segment streaming deltas (`text-delta`/`reasoning-delta`/`tool-input-delta`) credit at most once per throttle window via a per-isolate `StreamProgressCreditThrottle`. Previously `AIChatAgent` credited only on chunk-type milestones while `Think` credited on its flush cadence, so a long single content segment spanning repeated crashes could read as "no progress" under `AIChatAgent` and false-fire its `no_progress_timeout`. The new rule is never coarser than either host's prior cadence, so it can only delay or avoid a false no-progress timeout, never hasten give-up.

+- [#1788](https://github.com/cloudflare/agents/pull/1788) [`3b2af54`](https://github.com/cloudflare/agents/commit/3b2af5444af5002cd54fd493452e03c721d31999) Thanks [@threepointone](https://github.com/threepointone)! - Export `reconcileOrphanPartial` from `agents/chat`.
+
+  This is the shared primitive that merges a freshly-reconstructed orphaned stream
+  partial onto an assistant message that already owns its target id (an early
+  persist at tool-approval time, or a continuation resuming the prior assistant
+  message). It keeps all existing parts, appends only reconstructed parts whose
+  `toolCallId` is not already present (so a recovery replay never duplicates a
+  tool call), and overlays incoming metadata onto existing — preserving an
+  in-place tool result that lives only in storage rather than letting a replayed
+  chunk re-advance it. `@cloudflare/ai-chat`'s orphan-persist path now uses it;
+  hosts whose orphan persist only runs at stream finalize don't need it (the
+  shared reconstruction is already idempotent by `toolCallId`).
+
+  Additive export only — no behavior change to existing APIs.

+
+  This is the minimal message store the chat-recovery orphan-persist write goes
+  through — the write subset of `SessionProvider` (the `getMessage`,
+  `appendMessage`, and `updateMessage` methods). It is parameterized over the
+  host's message type so the seam itself is not AI-SDK-specific: the AI-SDK chat
+  hosts (`@cloudflare/ai-chat`, `@cloudflare/think`) instantiate it at the
+  `UIMessage` default, while `SessionProvider` satisfies it at its own
+  `SessionMessage`. Both hosts now route their orphan-persist write through a host
+  adapter typed against this interface, turning the previous by-convention
+  alignment into a type-enforced contract.
+
+  Additive export only — no behavior change to existing APIs.
