Project Chronicles A two-track documentation system that preserves both implementation history and product/process thinking across sessions. Built for the reality that future-you (or a future AI session) needs to orient fast — and that these two kinds of knowledge decay differently. The core distinction Working log — what changed and why. Tied to specific files, decisions, commits. Becomes outdated when the code changes; that's fine, it's a record. Usage notes — what you're learning about the problem, the product, the process. Observations about how the system behaves, where friction surfaces…
