# Reopened Bug Ledger

**Policy:** If a debug doc is moved out of `.planning/debug/resolved/` a second time, add an
entry here with the reopen date and a one-sentence root cause. Patterns in this ledger inform
future mitigation priorities.

See RETRO-AGENT-FAILURE-PATTERNS.md for the retrospective that established this ledger (F4, F6).
