Twenty lectures.
One company at a time.

The source builds twenty generic lecture cards, each with a manual checkbox and note area, forty editable controls. Checking five cards gives five of twenty complete, a derived quarter of the board. Bars share twenty five pixels per lecture, showing one hundred twenty five pixels for five and five hundred for twenty. The page displays the count rather than a percentage. It provides no actual transcript titles, lecture text or verified repository link. Completion is your assertion, not an assessed learning result. Checkboxes store zero based indices from zero through nineteen. Export adds one, so index zero becomes lecture one and index nineteen lecture twenty. Bars use twenty pixels per index or number to compare nineteen stored and twenty exported. Notes remain keyed by their original zero based indices. Completing and unchecking changes the stored set, not course materials, enrollment or a certificate. Completion order can remain the order of your clicks rather than numerical lecture order. Export has five properties: physical creation timestamp, fixed course label, completed lecture numbers, notes and an explicit no transcript reproduction scope. Bars compare twenty possible note areas with five top level export properties at twenty five pixels per item. Notes and completion choices persist locally after reload. Reset clears both the done array and notes object but keeps the generic twenty card board. This is a private study planning record, not proof of reading, learning or finishing the external course.
