Patch Changes

• #1659 f99f890 Thanks @threepointone! - Recover one-shot scheduled work (alarms) killed by a "This script has been upgraded…" deploy/code-update, not just "Durable Object reset because its code was updated.".

  _executeScheduleCallback only re-runs a one-shot schedule row after a superseded-isolate error if the error matched /reset because its code was updated/i. The platform also surfaces the same failure class as "This script has been upgraded. Please send a new request to connect to the new version." (a stub/connection to a superseded script), which fell through to the swallow-and-delete branch — the one-shot row was deleted and the work abandoned. For a queued submission this orphaned the pending row with no driver (no alarm, no retry) until something unrelated woke the Durable Object, leaving the user on an indefinite spinner.

  The superseded-isolate matcher now recognizes both messages, so either causes the row to be preserved and re-run on the fresh isolate under the at-least-once alarm guarantee. "Network connection lost." is intentionally not included (it is a connection error that may succeed on in-process retry, not an isolate replacement).

• #1661 41315b6 Thanks @threepointone! - Enforce the tool_use.input invariant at the chat write boundary.

  A streamed tool call that finishes with no input_json_delta events (the model called the tool with no args), or whose input surfaces as a stringified JSON blob, could persist a non-object input — null, undefined, "", an array, or a raw string. The Anthropic Messages API requires tool_use.input to be a JSON object and rejects every subsequent turn with tool_use.input: Input should be an object (verified against the live API: {} → 200, but "", [], and [{...}] all → 400). Because the bad shape lives in durable storage, the session is wedged across reconnects, redeploys, and DO evictions.

  applyChunkToParts (the shared accumulator used by @cloudflare/ai-chat and @cloudflare/think) now normalizes the finalized tool input on tool-input-available / tool-input-error: a plain object passes through untouched, a stringified-JSON object is parsed, and everything else (null/undefined/""/arrays/primitives/unparseable strings) collapses to {}. A new normalizeToolInput helper is exported from agents/chat so read-side transcript repair can enforce the same invariant.

• #1665 13d6db0 Thanks @threepointone! - Await Chat SDK state-agent cleanup scheduling during startup so tests and short-lived worker isolates do not leave dangling cleanup work.

• #1666 01a0b35 Thanks @dcartertwo! - Fix MCP OAuth PKCE verifier lookup for overlapping authorization attempts.

  DurableObjectOAuthClientProvider now binds pending PKCE verifiers to the OAuth callback state instead of storing a single verifier per client/server. Callback handling runs token exchange and verifier cleanup in the returned state's context, so older auth windows and retry churn no longer exchange an authorization code with another attempt's verifier.
