-- ════════════════════════════════════════════════════════════════════════════
-- WebDAV dead properties: rekey from (resource_path, user_id) to resource id
-- ════════════════════════════════════════════════════════════════════════════
-- The original schema (20260825000000) keyed dead properties on
-- `(resource_path, user_id, namespace, local_name)`. That model was wrong on
-- two counts:
--
-- 1. Dead properties are RESOURCE state per RFC 4918 §4.2 — not user
-- state. Two users on a shared drive PROPFIND'ing the same resource
-- must see the same dead-properties. The user_id key siloed them.
-- 2. Every non-WebDAV delete path (REST `DELETE /api/files/{id}`, bulk
-- delete, trash empty, folder cascade) operates on a resource id —
-- not a path. None of those code paths could cheaply call
-- `remove_resource(path, user_id)`, so they leaked dead-property
-- tombstones. WebDAV DELETE itself had a workaround explicit-cleanup
-- call, but the REST surface (which the SvelteKit web UI uses) is the
-- dominant delete path in practice.
--
-- This migration switches the key to a polymorphic resource reference:
-- exactly one of `folder_id` / `file_id` is set, each with `ON DELETE
-- CASCADE` to its owning table. After this lands every existing
-- delete code path — REST, WebDAV, NextCloud DAV, trash, folder
-- cascade — automatically reaps dead-property rows when the underlying
-- file or folder is removed, with no service-layer changes.
--
-- MOVE / RENAME also become no-ops at the dead-properties layer: a
-- folder's id is stable across renames, so its dead properties move
-- with it for free. The `rename_resource()` method on the store is
-- removed in the matching Rust change.
--
-- ── Migration shape ─────────────────────────────────────────────────────────
-- 1. ADD COLUMN folder_id / file_id (NULL-able for now).
-- 2. Backfill folder_id from any row whose resource_path matches a
-- folder row's `path` + `user_id`.
-- 3. Backfill file_id for the rest by joining through the parent folder
-- and matching `parent.path || '/' || fi.name`.
-- 4. Reap rows that didn't resolve — they're tombstones from before
-- the FK-cascade fix, and there's no resource left to attach them to.
-- 5. Add the CHECK constraint that exactly one column is set.
-- 6. Add two partial unique indexes (one per kind).
-- 7. DROP the old columns; PG drops the inline UNIQUE constraint and
-- the explicit path/user index along with them.
--
-- The migration runs in a single sqlx transaction. If any step fails
-- the schema rolls back to (20260825000000) intact.

-- Backfill: every row whose resource_path matches an existing folder

-- the live target of a PROPPATCH anyway, so any old row pointing at a
-- trashed folder is a tombstone (handled in step 4).

-- `parent.path || '/' || fi.name` — so the rewrite mirrors the
-- handler's runtime behaviour exactly.

-- Reap orphans. A row that didn't resolve to a folder or file is a
-- tombstone left by some pre-fix delete path: the resource is long
-- gone but the dead-property row was never reaped because the old
-- `(path, user_id)` key kept it disconnected from the resource's
-- lifecycle. The FK-cascade era makes this category structurally
-- impossible, so dropping them on migration is the right cleanup.
DELETE FROM storage.webdav_dead_properties
