# /log-session, end-of-session notes update Keep `.claude/PROJECT_NOTES.md` an accurate living snapshot and `docs/BUILD_LOG.md` an honest history. A fresh session reads both first, so write for that reader. ## Steps 1. Review the conversation: what got built, what was decided, what broke and how it was fixed, what was tested and at which rung. 2. Append to `docs/BUILD_LOG.md`, newest at the top, under the format header: ``` ## YYYY-MM-DD: short title **Did:** what actually changed **Tested:** which rung (compiles / bench / ring / match), and the result **Learned:** anything that changes a future decision **Next:** the immediate next action ``` 3. Update `.claude/PROJECT_NOTES.md`: - Recent activity log: add today's entry. - Open questions: close anything that got answered, and add anything new that emerged. - Next actions: rewrite so the top item is the literal next action. - What we know versus what we're assuming: if something moved from assumed to confirmed, move it and note the date. - Convert relative dates ("today", "last week") to absolute ones. 4. If a rule or event detail was confirmed this session, treat it as significant and follow the rule-change protocol in `.claude/rules/competition_rules.md`. Update `docs/RULES.md`, `docs/COMPETITION.md`, `AGENTS.md`, and re-check every design decision made under the old assumption. 5. If a ring test happened, make sure `docs/BUILD_LOG.md` records the actual pass and fail numbers rat
