Practice Log Music Block for Solid

Edit START: each session has a date, a skill, the minutes and a note, newest first, and AS_OF is the day the block treats as today. The week is the Monday-to-Sunday span around AS_OF; the totals, the day columns, the skill shares and the streak are all worked out from the sessions, so nothing is typed twice. SKILLS holds the skill names, and SCALE sets how many minutes fill a day column.

It counts the days in a row that have at least one session, ending today if today has one, and yesterday while today is still empty. In the sample, Monday to Wednesday have sessions and Thursday has none, so the streak is three days and the cell says that logging today makes it four. Day arithmetic uses whole days since 1970, so no time zone can shift a date.

Minutes must be a whole number from 5 to 180; anything else is refused with the reason in the status line and nothing is added. A valid session goes to the top of the history under today's date. Undo last removes the newest session you logged here, one at a time, and never touches the sample sessions; with nothing to undo it says so.

Everything: sessions, the goal and the streak live in the page and reset on a reload, and nothing is sent. To make it real, post the new session from the log handler, store it with its date, and return the week's sessions to the same shape; the goal needs a field on the user. Nothing here reads the clock, so replace AS_OF with the real date after mount.

Tab runs from the goal field to the form, the Log button and Undo last, then to the session history, which is a named scroll region you can focus and scroll with the arrow keys. The status line announces each result.

The three figures stack, the seven columns stay in one row, the skills sit under them, and the form fields wrap onto two lines. The history keeps its height and scrolls, so logging never moves the page.
