* fix(tts): pace classroom TTS and classify MiniMax RPM limits MiniMax reports RPM limits as HTTP 200 with base_resp.status_code 1002. Classify that code as TTSRateLimitError, pace classroom TTS with TTS_MIN_INTERVAL_MS (default 1000ms) and double the gap up to 15000ms on each rate limit, and store ttsCoverage on the generation job so a partial narration is not a clean success. Fixes #1567 * fix(tts): fail closed on MiniMax status and skipped narration Treat every non-zero MiniMax base_resp status as a failure, even when audio bytes are present. Classify 1002, 1039, 1041, and 2045 as rate limits. Floor rate-limit back-off independently of TTS_MIN_INTERVAL_MS, cap the cumulative wait, and cancel those sleeps on abort. A skipped or thrown TTS phase reports zero coverage and a warning. * fix(tts): decay spacing, heartbeat TTS progress, default interval 0 Classroom TTS spacing steps back toward TTS_MIN_INTERVAL_MS after each successful clip, and that interval defaults to 0 so pacing starts only after a rate limit. Clip progress is reported through the existing job onProgress path, so updatedAt keeps moving during a long narration phase. A Retry-After that does not fit the remaining back-off budget skips that clip instead of silencing every later clip. generateTTSForClassroom always returns coverage. A skipped run that has resolved a provider counts clips after the same speech split as synthesis. --------- Co-authored-by: wyuc <wang-yc24@mails.tsinghua.edu.cn>
