New operations runbook (enable/disable, fail-closed ApiKey rule, stop/start-
together, tombstone-retention window, MaxBatchSize row-count-vs-4MB, never
sqlite3-a-live-WAL-DB cp-triplet recipe). Configuration.md gains a LocalDb
section; Redundancy.md gains a pair-local config cache section (what boot-from-
cache does and does not cover); CLAUDE.md gains the Phase 1 scope paragraph.
