Why we publish syllabus diffs like open-source release notes

Every month we publish a diff against the previous syllabus: added labs, retired readings, and rationale paragraphs written for humans, not lawyers. The practice started after a cohort noticed a module quietly swapped reading order without announcement, which broke study groups that had pre-split the work.

Now, when we retire an exercise, we link to the replacement and explain the pedagogical reason—tighter feedback loops, fewer hidden dependencies, or a clearer bridge to portfolio review. Learners treat the feed like a changelog for their own calendars.

Instructors benefit too. Curriculum debates happen in the open, so newer mentors inherit context faster than digging through chat archives. We still protect partner-specific examples behind redaction markers, but the shape of each week stays visible.

If you mirror this internally, start with a single table: week number, change type, impact level, mitigation tip. That alone prevents silent drift.
