Nested tool calls: ToolExecutionApi.executeTool() runs another tool as its own pi.tool task owned by the caller,
keyed for replay-safe reattachment. Results for programs live in the caller's NestedResultDoc until it settles;
pi.live.nestedTools shows each call with the arguments it runs with and a summary. TaskOptions.abandonOnRestart
aborts work its creator awaited only in memory before it runs again after a restart.
Structured output: structuredOutputSchema and structuredOutput, validated; a tool without a schema gives programs its
bounded output (one text as a string, one image as itself, else the list). ToolExecutionResult.content is now output.
callers and modelTools decide who may call a tool.
Storage errors: any error a Storage method throws fails the Session, which closes itself; later calls and waits reject
with SessionFailed, watches end with session_failed, and Session.closed settles. Nothing retries in the Harness.
StorageRejected is removed; StorageRequestError marks invalid reads that fail only their call. Listener and onReport
errors are contained and reported.
Also updates scripts/issues/triage.ts and the vacation experiment for the content -> output rename.
- drop AsyncLocalStorage misuse guards from the Node adapter
- run calls immediately when the queue is idle; transactions publish their barrier before the callback starts
- SqliteStorage.close() waits for admitted multi-query reads and shares one close promise
Replace prepare/SqliteStatement with run/get/all(sql, ...params) on the database and transaction handles. The Node adapter caches prepared statements per connection, so transactions reuse them instead of preparing again on every commit.
Read documents in one transaction so a concurrent commit cannot replace the base between the record and revision queries.
