Correctness (3 confirmed + 2 plausible, all fixed): - drain_stream now raises typed, retryable IncompleteStreamError when a stream exhausts without any finish reason — every adapter emits one on a healthy stream, so its absence means the generation died mid-response behind a cleanly-closing proxy. This restores the retired transport's complete-or-error contract (a half-generated compaction summary was previously returned as finish=stop and stored, silently replacing real history) and DELETES round 1's suffix-info fold: with no finish-less success path there is nothing to classify, so a trailing status ping can never be stored as content either. - Index-degenerate parallel tool calls get distinct slots: a delta whose id differs from its slot's opens a new call (id-less fragments still follow their index's current call), so historical compat servers that emit every parallel call at index 0 no longer fuse distinct calls into concatenated garbage arguments. Result order stays index-sorted (stable) like the retired array parse. - response.failed retryability is code-gated: only transient codes (server_error, rate_limit_exceeded) raise the retryable typed error; deterministic rejections (invalid prompt, image fetch, policy) raise plain RuntimeError and stop retry loops on attempt zero instead of running the full backoff ladder against a doomed request. - Terminal Responses events rebuild provider_blocks from response.output when present: the item being generated at max_output_tokens truncation never receives output_item.done, and storing a reasoning item without its required following item made the next turn's replay a 400. - merge_usage's base case uses dataclasses.replace so a future UsageInfo field can't be silently zeroed on drained lanes. Cleanup: run_abortable_with_deadline bundles the three-point abort wiring (ref + cancel_ref + on_abandon) so it cannot be half-wired — both judges converted; scripted_chat_client hoists the 14 chat-lane fake_create closures (call scripts + .calls recording replace per-test counter cells); fake_chat_stream gains reasoning=, collapsing the reasoning-capture suite's hand-rolled chunk shape; FakeAnthropicBlock hoists the duplicated _Block test class; the class and judge PlantUML diagrams drop the retired create_completion flow. Also converts test_model_registry's agent-model fakes, which returned legacy response objects that iterated as EMPTY streams — they only passed through the old drain's silent finish=stop default, exactly the hazard the new gate exists to catch.
