Backend:
- ClosedWeekStore.SumDelta: single SQL aggregate returning total delta_ms and
row count across all closed_weeks
- WeekService.Balance: thin passthrough returning BalanceResult{TotalDeltaMs, ClosedWeekCount}
- GET /api/weeks/balance handler; route registered alongside /weeks list/close/reopen
- Tests: store-level SumDelta (empty + populated), service-level Balance (empty + 2 weeks)
Frontend:
- weeks.balance() added to API client
- History page: balance card at top, fetched in parallel with existing data
- Loading state shows '—'; once loaded shows formatDelta value in green/red/gray
- Shows 'across N closed weeks' count alongside the value
The naive formula used (jan4.Weekday() - time.Monday) produces -1
when Jan 4 is a Sunday (Weekday()==0), shifting the computed Monday
one week forward. 2026 is affected: Jan 4 is a Sunday, so every
week key in 2026 was mapped to the wrong 7-day range, causing
CloseWeek to look for closed_days on the wrong dates and finding
nothing — resulting in worked_ms=0 and a full -Nh delta.
Fix: use (weekday+6)%7 to get days-since-Monday (Mon=0…Sun=6),
which is always non-negative.
Adds table-driven TestWeekDayKeys covering 2024 (Thu), 2026 (Sun),
and 2023 (Wed) to prevent regression.
When a day is closed, re-closed, or reopened, DayService now
recomputes worked_ms and delta_ms on the closed week containing
that day (if the week is already closed). This prevents stale
delta values after editing entries and re-closing a day.
- DayService.recomputeWeek: sums worked_ms from all closed_days
in the week, updates closed_weeks row preserving expected_ms
- NewDayService now takes ClosedWeekStore
- WeekKeyForDayKey exported helper (used by DayService)
- TestWeekSnapshotUpdatesWhenDayReopened regression test
Previously any past workday without a closed_days record blocked week
close. Now only days that actually have entries require an explicit
close. Empty workdays count as 0h worked, which is reflected in the
weekly delta automatically.
- WeekService.CloseWeek: after finding no closed_days record, check
whether the day has any entries; only error if it does
- NewWeekService: takes EntryStore to support the above check
- Updated TestCloseWeekMissingDayFails to reflect the new semantic
(test now creates entries on Friday but leaves it unclosed)
CloseWeek was requiring every workday in the ISO week to have a
closed_days record, including days in the future. Now only workdays
up to and including today are checked; future workdays are skipped.
Adds TestCloseWeekMidWeek regression test.
