//! server without interpreting their value. Properties are persisted to
//! `storage.webdav_dead_properties` and survive server restarts.
//!
//! Queries here use `sqlx::query()` (runtime-bound) rather than the
//! compile-time-checked `sqlx::query!()` macro. The macro would require either
//! a live DB at compile time OR committed `.sqlx/` offline metadata; the rest
//! of this codebase consistently uses the runtime variant (see
//! `user_pg_repository.rs` for the canonical style), so a fresh checkout
//! compiles without any DB connection. Trading the macro's compile-time column
//! check for that bootstrap-friendliness is the project's standing convention.
//! Keying contract (after migration 20260830000001): the row is keyed by
//! the underlying resource id — exactly one of `folder_id` / `file_id` is
//! set — not by the resource's current path. Three consequences:
//!
//! * Every delete code path (REST, WebDAV, NextCloud DAV, trash empty,
//! folder cascade) reaps dead-property rows for free via FK
//! `ON DELETE CASCADE`. The store has no `remove_resource()` method
//! because it isn't needed: deleting the file/folder row reaps the
//! attached dead properties as a database invariant.
//! * MOVE / RENAME never changes the resource id, so dead properties
//! follow the resource without any store-side bookkeeping. The store
//! has no `rename_resource()` method for the same reason.
//! * Dead properties are RESOURCE state (RFC 4918 §4.2), not user
//! state. Two users on a shared drive PROPFIND'ing the same resource
//! see the same dead properties. The `user_id` scope key from the
//! pre-rekey schema is gone; user-delete cleanup happens
//! transitively through `auth.users` → `storage.{folders,files}` →
//! this table.
//!
//! Queries use `sqlx::query()` (runtime-bound) rather than `sqlx::query!()`
//! to keep fresh checkouts compilable without a DB connection — the
//! codebase's standing convention.
//!
//! COPY semantics (RFC 4918 §8.8 — dead properties MUST be duplicated)
//! are NOT handled here. The COPY handler is responsible for explicitly
//! reading the source's dead properties via `get_all()` and writing them
//! against the new resource id via `set()`. Not done in this migration —
//! it was not handled by the path-based store either, so this is a
//! parity decision, not a regression.
