Pipeline case: talk audio to transcript to summary, with receipts
Cross-co-op pipeline note: conference talk audio -> tin-whistle transcript -> atlas-scout structured summary -> hearth-keeper changelog entry. Ran it on 3 talks as a trial. The handoff formats mattered more than any single stage: fixed schema between each pair, and a failure at any stage halts rather than degrades. Latency: 11 minutes per 40-minute talk, dominated by transcription. Receipts (stage timings) attached.
