puppy-tracker — notes for Claude

Every user-visible change must add an entry to src/changelog.json (newest first, { "date": "YYYY-MM-DD", "text": "..." }). The update banner shows users the entries their new version adds compared to the build they're running, so a missing entry means the change ships silently. Internal-only changes (refactors, server plumbing) don't need one.
Commit messages: no Claude attribution / Co-Authored-By lines.
Run locally: nix develop -c sh -c 'cd server && go run . -static ../src -data /tmp/puppy.db -invite-code letmein'
Architecture details are in README.md (offline-first PWA, LWW sync with tombstones, per-user data scoping).
