+# ADR 0033: Restore De-Duplicates The Node Name On Sibling Conflict
+
+## Status
+
+Accepted.
+
+## Context
+
+ADR-0031 defined restore as "clear `deletedAt` on that node only". It did not cover
+the case where a same-name sibling was created **after** the deletion: D14's partial
+unique index (active siblings, case-insensitive) then rejects the restore with a 409
+`conflict`, leaving the entry permanently stuck in the bin — unrecoverable for
+non-admin users (who cannot purge) and cryptic for admins.
+
+## Decision
+
+Restore never fails on a name conflict. Before clearing `deletedAt`, the service
+checks active siblings; if the node's name is taken, it restores as
+`原名(已恢复)`, then `原名(已恢复 2)`, …, first free key wins (suffix is included
+in the `NODE_NAME_MAX_LENGTH` budget by truncating the base). The rename is part of
+the same transaction and is recorded in the restore audit entry as
+`{ name, renamedFrom }`. The API returns the final name so the UI can tell the user.
+
+Rationale: the bin's purpose is recovery; a restore that can deadlock on naming is a
+trap, not a safeguard. Users who care about the name can rename afterwards (they have
+MANAGE by definition of bin visibility).

+# ADR 0034: Permanent Delete Follows MANAGE, Not Website Administrator
+
+## Status
+
+Accepted. **Supersedes one clause of ADR-0031**: "Permanent delete (彻底删除) is
+website-administrator only".
+
+## Context
+
+ADR-0031 gated 彻底删除 to the website administrator as a high-risk-operation
+precaution. The product call is that this is inconsistent with the rest of the
+permission model: soft delete already requires only MANAGE on the node, and a
+MANAGE holder who can delete a node into the bin should also be able to purge it —
+the authority that grants deletion grants destruction. Admin-only purge strands
+non-admin managers with bins they cannot empty.
+
+## Decision
+
+Permanent delete uses **the same visibility rule as the bin entry itself**: website
+administrator, or an actor with an active MANAGE grant on the deleted node (direct
+grant, USER or resolved GROUP). Anyone else gets 404 (D8). The double confirmation
+in the UI and the `node.purge` audit entry are unchanged.
+
+## Consequences
+
+- Purge auth = restore auth = bin-entry visibility: one rule, three surfaces.
+- The operation remains irreversible and audited; no new capability is granted to
+  anyone who could not already delete the node (soft) and see it in the bin.

+# ADR 0035: Restore Keeps The Original Name; Conflict Is A Clear Error
+
+## Status
+
+Accepted. **Supersedes ADR-0033** (restore de-duplicates the node name on sibling
+conflict).
+
+## Context
+
+ADR-0033 made restore auto-rename to `原名(已恢复)` on sibling name conflict so
+restore never fails. In practice the suffix is unwanted noise - operators expect the
+original name back and prefer to resolve conflicts themselves.
+
+## Decision
+
+Restore clears `deletedAt` and keeps the node's **original name**. If an active
+sibling now occupies the same name (D14 partial unique index), the service throws a
+`409 name_conflict_on_restore` with a human-readable message ("同名节点已存在，请先
+重命名现有节点再恢复") - no silent renaming, no suffix. The restore audit records
+the original name only.
