Home hides last night's sleep until the data edge is 1 h past wake, while the Sleep tab already shows it. #638
Description
What happened?
On Android (0.11.3), the morning after sleep, the Sleep tab already shows last night, but Home says "Last night is still being worked out" and shows no sleep for about an hour, and for hours if the band stops recording after waking. Two users reported the same thing.
Expected: Home shows the night as soon as the Sleep tab can, marked as still updating if it can still change.
Measured on a live band (local times, 2026-10-27, from two in-app database exports):
| export 08:40 (Home stuck) | export 09:32 (Home settled) | |
|---|---|---|
| sleep window | 00:32 to 08:26:36 | 00:32 to 08:17:38 |
| newest synced record | 08:26:36 | 09:27:02 |
| edge past wake | 0 min | 1 h 09 min |
| overnight / recovery state | building / night_in_progress | ready / final |
Cause: overnightSettled() in lib/compute/derivation_engine.dart only lets Home show today's night once the newest record is at least 1 h past wake, or 12 h after wake. While a sync is arriving, the stager closes the window at the newest record, so the "wake" is just where the sync stopped (here wake equals edge to the second).
The Sleep tab reads the stored row with no such gate. If the band keeps syncing, Home waits for the next sync and derive (about 70 min here). If the band stops recording after waking, it waits for the 12 h give-up.
This is the intended trade-off of #448 / #490, and #578 added provisional and final recovery states. It just hides the sleep figures longer than needed.
Proposal:
- Home shows a provisional night's sleep figures labelled "still updating", like the Sleep tab. Readiness stays withheld until final, as in fix(recovery): provisional/final states, no early pins, one headline source (refs #543) #578.
- Settle early when the band is quiet, with a persisted "drain complete" marker, so a charging band doesn't wait 12 h.
Question: is showing a provisional night on Home acceptable given #448?
Steps to reproduce
Wear the band overnight and sync. Open Home right after waking: the Sleep tab has the night, Home says "Last night is still being worked out". It happens most mornings.
It clears about an hour after wake if the band keeps syncing, or at wake + 12 h if it stops.

Adding a vote for the narrow half of this, since it's the most visible open bug in the tracker (most mornings, two reporters).
@abdulsaheel the open question is the one in the issue: is it acceptable for Home to show a night that
overnightSettled()hasn't settled yet, the way the Sleep tab already does?If yes, I'd keep the change small:
overnightSettled()itself, and no settle-early marker for now (that's the riskier half).Happy to open that as a PR if the direction is OK.
