Ramnique Singh 21c93913f4 fix(x): validate turn event batches before they become durable ... The commit ritual persisted first and reduced second, so an illegal append (e.g. a misbehaving tool reporting progress after its terminal result) became durable before the reducer rejected it — permanently corrupting the turn file and, through context references, blocking every later turn in the session. Reduce the batch against the in-memory history first: illegal batches now reject in memory for their caller only, the file stays legal, and a failed commit no longer poisons this.events for subsequent appends in the same invocation. Adds a test that fires a stashed reportProgress after the tool's result is durable (while a sibling keeps the invocation alive) and asserts the late append rejects, nothing illegal reaches the file/stream/bus, and the turn completes and stays re-advanceable. Updates the design doc (§4.5, §24) to the reduce → persist → stream order. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>		2026-07-10 22:32:33 +05:30
