## [1.43.0] - 2026-09-22 > **BREAKING** — `aimock -h` is `--help`, not `--host`: `aimock -h 0.0.0.0` exits 1 with `Error: > Unexpected argument '0.0.0.0'. This command does not take positional arguments`. Migration: > `--host <string>` (long form only). The `llmock` bin (the Docker ENTRYPOINT) keeps `-h, --host` > (#453). ### Added - OpenAI GPT-Live mock, record and offline replay on `GET /v1/live/sessions`, with `onLive` fixtures (#468) - Live sessions enforce message/audio/queue/lifetime limits; recordings sanitize credentials (#468) - Live drift canaries for lifecycle, audio/transcript, delegation and usage, attributed to `openai-live` (#468) - Chaos `rateLimitRate` / `--chaos-ratelimit`: deterministic 429 with `Retry-After` (#449) - Chaos `latencyMs` / `--chaos-latency` now actually delays responses on every path (#449) - OpenAI Files API mock — byte-exact uploads, create-purpose enum, CORS on faults (#445) - OpenAI fine-tuning jobs mock — deterministic lifecycle, events, cursor pages (#447) - OpenAI Batches API mock — create/list/retrieve/cancel with real output files (#446) - `X-Request-Id` echoed or minted on every response; `?requestId=` filters the journal (#450) - `aimock validate` lints fixture files or directories offline, failing on broken files (#453) - ElevenLabs Voice Design record/replay — design, save-as-voice, and voice slot management (#452) - ElevenLabs Voice Design provenance block and strict-mode 503 coverage (#454) ### Changed - **BREAKING:** `aimock -h` is `--help`, matching `aimock convert -h` and `aimock validate -h`; the host override is `--host` only. The `llmock` bin (the Docker entrypoint) keeps its own `-h, --host` — see the note above (#453) - `aimock --config ""`, `--port ""` and `--host ""` are usage errors naming the option (#453) - Realtime `OpenAI-Beta: realtime=v1` now returns the real sunset rejection, not a session (#461) - `POST /v1/images/variations` now replays the real removal 404; OpenAI deleted it (#462) - `ChaosAction` gains `"rateLimit"` — an exhaustive switch over it needs a case (#449) - `applyChaosAsync()` returns `false | "handled" | "unwritable"` instead of a bare `boolean` (#449) - Journal `headers` now ALWAYS carry `x-request-id` — exact `toEqual` asserts break (#450) ### Deprecated - Synchronous `applyChaos()` warns once per process; it skips chaos latency. Use `await applyChaosAsync(...)` (#449) ### Fixed - Reasoning-first chat streams with content and tool calls carry the assistant role in the first chunk (#470) - Journals and metrics reflect delivered vs interrupted responses; one-shot errors never double-deliver (#466) - Nonstreaming OpenAI chat returns block text and tools; text-only blocks finish normally on every provider (#467) - AG-UI drift reads generated 1.0 schemas; `AGUIRunStartedEvent` gains optional `protocolVersion` (#469) - Drift reports list `unverifiedSurfaces`; offline Bedrock/Vertex checks no longer skip silently (#460) - Drift docs match actual coverage; ElevenLabs drift separates vendor observations from fixture checks (#465) - Chaos no longer treats committed headers as a dead response; only status-writing actions are skipped (#449) - Chaos skip logs name what happened; `aimock_chaos_triggered_total` counts only written responses (#449) - A request whose chaos latency was cancelled by client hang-up is no longer served or journalled (#449) - Moderations echoes the request's `model`; default is now `omni-moderation-latest` (#459) - Image endpoints default to `gpt-image-1` — `dall-e-2`/`dall-e-3` were removed (#459) - AG-UI record/proxy forwards the caller's headers and raw body upstream; `Accept` is forced to SSE (#455) - The AG-UI recorder refuses to write a fixture from a non-stream or empty 2xx upstream reply (#455) - A MINTED `x-request-id` is no longer forwarded upstream in record/proxy mode (#450)
