…ndows records - suunto_nautic_device_handshake_acknowledged: the open succeeds when only other frames arrive before the link goes quiet (a sleeping watch), so apps can tell the user to press a button when the first request times out - the water temperature range comes from the /Summary Windows records, which hold Temperature.Min/Max in schema order on both watches; Ocean firmware writes the dive record's pair reversed. The dive record stays the fallback Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>

Two items from deepsealabs/libdc-swift#29 (trustthegoose, build 19 report):
suunto_nautic_device_handshake_acknowledged(device): 1 when the watch sent its Hello-Ack on open. The open carries on when only other frames arrived before the link went quiet, which is how a sleeping watch looks; its first request then times out (-7). Exposed so apps can say "press a button on the watch"./SummaryWindows records (2-4, Temperature.Min/Max at +101/+105). Both watches write those in schema order; Ocean firmware writes the dive record pair reversed. Lowest min / highest max across the Windows; the ordered dive record pair is the fallback.Tested from libdc-swift: fake-watch tests for the flag (acknowledged / withheld), a synthetic summary where the Windows disagree with a reversed dive record, and the git-ignored capture corpus (Ocean + Nautic dives checked against the Suunto app: 16 read the Windows, including the Ocean dive with the reversed pair).
