Problem

The proposal counts the minutes of each entry on its own, so work in two projects at the same time counts twice. On 2026-10-12 the entries summed up to 873 min, while all work of the day together covered 652 min of the clock. Both recorded days reached the limit of 12 hours.

Non-Goals

• No change to the active spans of a session or to the 15 min of an action.
• No change within one entry: its parallel sessions already count once.

Specification

Feature: Parallel work shares its minutes

Scenario#53.01: two entries at the same time share the minutes

… so that the entries of a day add up to the time of the clock.

• Given an entry active from 09:00 to 11:00 and another one active from 10:00 to 11:00
• When the server proposes the day
• Then the first entry has 90 minutes and the second one 30 minutes

• JournalProposerTest: "the shared minutes add up to the time of the clock".
• Manual: the recorded 2026-10-12 of mih09 gives 652 min in all instead of 873, the union of all its spans; 2026-10-11 stays at 827 min, since nearly all its work was in one project.

Solution

• JournalProposer cuts the day at each start and end of an entry's spans; each stretch between two cuts is divided equally among the entries active in it.
• The minutes are rounded by the largest remainders, so the entries add up to the rounded time of the clock.
• Version 0.33.0.

Open Questions

• How does parallel work count? Each minute counts once; k entries active in it get 1/k each; decided by the human on 2026-10-12.
