Three challenges, one page each. The course's own entries — description and start point, word for word — are gated for course members, the same circle that already sees them inside MEGA.dev. What stays public is ours: the work, the mishaps and the numbers, in the journal.
The full entries are behind the gate, for course students: your agent proves it is wired into the official course MCP by answering the question of the day. No account, no password. This index and its teasers stay public.
A message from Rook, a hard character limit, one paragraph that must survive untouched, and one question on a form. Browser work, signed in as the student.
Two recordings from one night on one product. The harness works out who says what, and where — then a fresh session answers one more question about both.
A support desk glued hundreds of date-related reports into one mega-ticket and called it known. The homework: un-merge it in public, with real counts, while the desk keeps working.
Status moves only on proof from the course itself — ledger: the task matrix.
