Session Logs
The running history — what changed each working session and why. One file per
day in month folders: sessions/YYYY-MM/YYYY-MM-DD.md.
../status.md holds the current state; these hold the story.
The system
Append to today's file (create it + the YYYY-MM/ folder if it's the first
entry of the day). Newest entry on top. Skeleton:
# YYYY-MM-DD — Session Log
## <short title> — <one-line outcome>
What changed, root cause if a bug, files touched, verification result, follow-up.
Plain English, no diff noise.
Cross-link to ../reference/ for reusable lessons and ../status.md for current
health. The changelog (../version.md) is per commit; this is per day.
