Accidental admin deletes of users/roles/subscriptions/plans/tariffs were hard and unrecoverable. Now they soft-delete into a recycle bin. Schema (migration 0012): nullable deleted_at + deleted_by on users, roles, subscriptions, subscription_plans, tariffs. Additive ADD COLUMN; verified against a copy of the live DB. Backend: each resource's DELETE route STAMPS instead of removing; every catalog list filters deleted_at IS NULL. New recycle-bin module + routes (GET /api/recycle-bin, POST .../restore, DELETE .../:id purge) gated on a new recyclebin:read/update/delete permission. A 6-hourly + startup sweep auto-purges items older than RECYCLE_BIN_RETENTION_DAYS (default 30; 0 = forever). Invariants: soft-deleted users can't log in (login rejects deleted_at; no-lockout counts live admins only); a soft-deleted subscription doesn't open the barrier; plans are versioned so a delete stamps all versions of the plan_id (bin shows one item); username/role-name UNIQUE spans deleted rows so reuse returns a clear 409 pointing at the bin; restore doesn't auto-cascade a dangling role (guard resolves missing role to empty perms). The signed append-only ledger is OUT of scope (no delete path). Web: a Recycle bin tab under Setup (RecycleBin.tsx) with Restore/Purge + purge confirm; api client + i18n (sq + en parity). Tests: recycle-bin.test.ts (9 unit) + recycle-bin-routes.test.ts (4 integration: delete -> can't-login -> restore -> login, purge, gating, 409 reuse). server 103/103; build+lint+test 19/19. Wiki: new concepts/soft-delete.md; local-jwt-auth + index + log updated. Claude-Session: https://claude.ai/code/session_01Xcm6ikLgGoCxxHrxtjkk5V
