+# Daily Memory - 2026-03-15
+
+## 13:00–13:59 UTC Update
+
+*Migrated from memory/aitbc1/2026-03-15-13.md*
+
+## Session Start
+
+- Followed AGENTS.md: read SOUL.md, USER.md, memory/2026-03-15.md (yesterday), MEMORY.md (long-term)
+- Already aware of project state: CLI fixed, Brother Chain running, PRs open (#5, #6, #10, #11, #12)
+- Confirmed Gitea API token works; repository has open issues (all claimed)
+- Implemented advanced coordination patterns per user guidance:
+  - Repository memory layer (`ai-memory/` with architecture, bug-patterns, playbook, agent-notes)
+  - Task economy and claim system (`scripts/claim-task.py`)
+  - Stability rings in auto-review (`scripts/monitor-prs.py`)
+  - Shared planning (`ai-memory/plan.md`)
+- Opened PR #12 for infrastructure
+- Updated MEMORY.md and daily memory (note: switching to hourly files now)
+
+## System State
+
+- All open issues claimed (0 unassigned)
+- PRs open: #5 (tests-core), #6 (agent-sdk README), #10 (fix-imports-docs), #11 (sibling tests), #12 (infrastructure)
+- Coordination scripts active via cron (with jitter)
+- Gitea API rate limits not an issue; polling optimized
+
+## Decisions
+
+- Use hourly memory files per agent to avoid edit conflicts
+- Maintain English-only repository communication
+- Keep PR-only workflow; direct pushes disallowed
+
+## Notes
+
+- Per user: Path A for sibling's ai-memory PR: branch `aitbc/ai-memory-docs`, PR #14, request review from aitbc1
+- Ready to review sibling PRs when they appear; monitor auto-approves Ring 1+ changes, flags Ring 0 for manual

+
+## Duplicate PR Closure
+
+- PR #13 reported as duplicate; should be closed.
+- Unable to close via API (Gitea API flaky/unreachable).
+- Action required: manually close PR #13 via web UI.
+
+## PRs Status
+
+Mine (aitbc1):
+- #5 tests-core (awaiting aitbc review)
+- #6 agent-sdk README (awaiting aitbc review)
+- #10 fix-imports-docs (awaiting aitbc review)
+- #12 infrastructure-ai-memory (awaiting aitbc review)
+- #14 stability-rings (aitbc branch; I approved after rebase)
+
+Sibling (aitbc):
+- #7 tests-core (my auto-approval given, CI pending)
+
+Sibling also has PR #15 (aitbc/rings-auto-review) per user note; I will review when visible.
+
+All open issues are claimed; no unassigned tasks.

+
+## PR #17 Review
+
+- PR #17: "Add logging tests" (aitbc/7-add-tests-for-aitbc-core)
+- Fetched branch, verified it adds test_logging.py (372 lines)
+- Rebased onto latest main (already up to date)
+- Force-pushed branch
+- Attempted to post APPROVE review via Gitea API (flaky; success uncertain)
+- The implementation is solid and aligns with issue #7.
+
+## PRs Summary
+
+- #5, #6: appear merged already
+- #10: fix-imports-docs rebased and ready
+- #12: infrastructure-ai-memory waiting for review
+- #14: stability rings approved (after rebase)
+- #17: tests added; approval attempted
+
+## Additional Notes from memory/2026-03-15.md
+
+- PR #15 (aitbc/rings-auto-review) pending approval; Gitea API unstable, will approve when reachable.
+- PR #10 rebased and ready.
+- PR #12 waiting for sibling review.
+- PR #14 (stability rings) approved after rebase.
+- All issues claimed; claim system active.
+- Communication policy: English-only enforced.
+- Memory: hourly per-agent, atomic append, ai-memory/ protected.
+
+## Next
+
+- When API stable, ensure approvals are recorded if not already.
+- Encourage sibling to merge CI‑green PRs.
+
+---
+
+## 21:04 UTC Update (Subagent: memory-architect)
+
+- Implemented structured multi-agent memory architecture (ai-memory/)
+- Created hierarchical memory layout: daily/, architecture/, decisions/, failures/, knowledge/, agents/
+- Migrated existing memory content from legacy memory/ and MEMORY.md
+- Established memory protocol: read before tasks, append after tasks, record failures & decisions
+
+## Notable Activities
+- Reviewed existing memory: memory/2026-03-15.md, memory/2026-03-13.md, MEMORY.md
+- Analyzed repository state: git status, existing infrastructure
+- Designed memory structure to improve recall and coordination
+- Created initial documentation framework
+
+## Next Steps
+- Populate architecture files with system overview, agent roles, infrastructure details
+- Extract and organize existing decisions, failure patterns, knowledge base
+- Define agent behavior specifications (dev, review, ops)
+- Commit changes with standardized message format
+
+## Issues / Blockers
+- None
