Multi-Loop Collision — CI Sweeper vs PR Babysitter on PR #318

Setup

  • CI Sweeper: /loop 15m, max 3 attempts
  • PR Babysitter: /loop 10m, same repo
  • Shared branch: fix/auth-token-refresh on PR #318

What Worked

  • Both loops correctly identified the failing auth test
  • State files showed the overlap when we audited Tuesday morning

What Broke

  • CI Sweeper spawned a worktree fix at 14:02
  • PR Babysitter spawned a different minimal fix on the same PR at 14:07
  • Two commits, conflicting approaches, reviewer confused
  • Combined token spend for that PR: ~400k (normally ~80k)

Metrics

Metric Value
Duplicate fix attempts 2
Human minutes to untangle 45
Root cause No acting_on collision check

Lesson

Action loops need a branch lock in state. We added collision detection to multi-loop.md: read all pattern state files before spawning a worktree. CI Sweeper now owns red CI; PR Babysitter skips if ci-sweeper-state.md shows acting_on for that PR.
