…nd errors Speaker turns, diarize and speaker-count hints, tag_audio_events, request ids, per-model formats and limits, hour-long Pro recordings, client timeouts, and the error contract. Word-level segments, model-header fallback, per-model language behaviour, a parser that keeps untagged leading text, and a MessagePack example with a real timeout.

Request fields per model, response fields (speaker_turns, request_id, language rules), limits, formats, model-header fallback, and the status/code error table. Request ids on the observability page; ASR rows in errors and introduction. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
…ooks Captions group word-level segments into readable SRT/VTT cues; the batch recipe records a failed file and continues; language-hint wording matches the API. Test specs follow the new block order. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
duration is in seconds, timestamps have no 30 s latency rule, Pro is selected by header, and the SDK skill says which fields 1.3.0 exposes and how to reach the rest over HTTP. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Pro capabilities and model-header fallback on the models page, ASR concurrency on the pricing page, compat diarize note, and seconds (not milliseconds) in the legacy pages. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
transcribe-1-pro is listed first and recommended in every model table and list, and every example (features, API reference, cookbooks, skills, SDK reference snippets, compat pages) selects it with the model header. transcribe-1 details are condensed into short notes. Long-recording guidance uses one timeout story: a 15-minute client timeout in the examples and the Node.js fetch 5-minute limit with undici@7, without quoting SDK defaults.

- Line 10: Update the `vtt` case in the specs configuration to identify
`captions.vtt` as `vtt`, and update the JavaScript harness validation to require
the `WEBVTT` header for that format. Keep the existing SRT cue check for SRT

Validate captions.vtt as WebVTT.
The vtt case is currently labeled "srt". The JavaScript harness only checks that an SRT file contains "-->", which also appears in WebVTT. A regression that writes SRT syntax to captions.vtt can therefore pass. Add a WebVTT header check and label the case as "vtt".

Update the `vtt` case in the specs configuration to identify `captions.vtt` as
`vtt`, and update the JavaScript harness validation to require the `WEBVTT`
header for that format. Keep the existing SRT cue check for SRT cases.
