`[2026-07-01]` **Tier-3 stores RESET (operator-directed).** `memory.db` (29 chunks + vectors + idempotency) + `affect.db` (5 PAD snapshots + idempotency) wiped to zero via a live `DELETE`+`wal_checkpoint` through the shared WAL (no provider restart — the 3 long-running providers see empty on next dispatch); consistent online-backup at `/tmp/ratatoskr-tier3-reset-<ts>/`. **Boundary for a COMPLETE Sindra wipe (mapped):** our stores = mine (done); the agent DEFINITION `ratatoskr:sindra` + its sessions = mine via the owner key (DELETE, no coordination); Worldtree's internal promotion/dedup shadow = needs worldtree-dev (no public reset API, survives our wipe → for a clean promotion smoke use a BRAND-NEW agent+end_user).
