38 minutes: building the planner that reads my calendar
One sitting, one feature, unedited — including eleven minutes lost to a bug that was my own test fixture.
PlaceholderThis is the whole build, uncut, including the eleven minutes I spent chasing a timezone bug that turned out to be my own test fixture. I leave those in deliberately. Edited build videos teach you that building is smooth, and that is the most expensive lie in this genre.
The feature: read the next seven days out of a calendar, classify every block as committed, movable or junk, and hand back the three windows where real work can actually happen. The model does the classifying. The rules — what counts as junk, how much recovery a bad day earns — are mine, written in plain text, and they are on screen at 12:40.
The file is linked under the video. Take it. The classifier is forty lines and it is not the hard part. The hard part is deciding what your week is supposed to feel like, and no model is going to do that for you.
