# Debug Operations Systematic debugging methodology with language-specific tooling and common scenario playbooks. ## Bug Classification Decision Tree ``` Bug Report / Symptom │ ├─ Crash │ ├─ Segfault / Access Violation │ │ └─ Check: null pointer, buffer overflow, use-after-free, stack overflow │ ├─ Panic / Fatal Error │ │ └─ Check: assertion failure, unrecoverable state, out-of-memory │ └─ Unhandled Exception │ └─ Check: missing error handler, unexpected input type, network failure │ ├─ Hang │ ├─ Deadlock │ │ └─ Check: lock ordering, mutex contention, channel blocking │ ├─ Infinite Loop │ │ └─ Check: loop termination condition, counter overflow, recursive call │ └─ Blocked I/O │ └─ Check: network timeout, DNS resolution, disk full, file lock │ ├─ Wrong Output │ ├─ Logic Error │ │ └─ Check: operator precedence, boundary conditions, boolean logic │ ├─ Data Corruption │ │ └─ Check: concurrent mutation, encoding mismatch, truncation │ └─ Off-by-One │ └─ Check: loop bounds, array indexing, fence-post errors │ ├─ Performance │ ├─ Slow Queries │ │ └─ Check: missing index, N+1 queries, full table scan, lock wait │ ├─ Memory Bloat │ │ └─ Check: cache without eviction, leaked references, large allocations │ └─ CPU Spikes │ └─ Check: hot loops, regex backtracking, excessive GC, busy-wait │ └─ Intermittent ├─ Race Condition │ └─ Check: shared mutable state, read-modify-write, check-then-act ├─ Timing-Dependent │ └─ Check: timeo...
