Reviewed the runner/orchestration flow end to end from the agent side.
Main conclusion: the system is workable but not yet flowing. The biggest execution-friction point was that worktree tasks did not explicitly tell the agent the real task ID, execution root, checked-out branch, or where the shared runtime .brr/ directory lives. In this run, the task body said to use branch brr/evt-1776172059-5rn4, while the actual checked-out branch was brr/task-1776172089-sdlf. I fixed that prompt gap in src/brr/runner.py and src/brr/daemon.py, added coverage in tests/test_runner.py and tests/test_daemon.py, restored the missing KB page kb/review-concurrency-followup-2026-04-14.md, appended kb/log.md, and wrote the detailed review artifact to .brr/reviews/evt-1776172059-5rn4.md.
Other high-value recommendations are in the review artifact: add a small brr inspect command or per-task manifest linking event/task/trace/review paths, reduce triage prompt bloat, and add a short KB executio
