+# Metadata Value Search & Entry Relations (DAG)
+
+## Overview
+
+Two new features for secrets-mcp:
+
+1. **Metadata Value Search** — fuzzy search across all JSON scalar values in `metadata`, excluding keys
+2. **Entry Relations** — directional parent-child associations between entries (DAG, multiple parents allowed, cycle detection)
+
+---
+
+## Feature 1: Metadata Value Search
+
+### Problem
+
+The existing `query` parameter in `secrets_find`/`secrets_search` searches `metadata::text ILIKE`, which matches keys, JSON punctuation, and structural characters. Users want to search **only metadata values** (e.g. find entries where any metadata value contains "1.2.3.4", regardless of key name).
+
+### Solution
+
+Add a new `metadata_query` filter to `SearchParams` that uses PostgreSQL `jsonb_path_query` to iterate over only scalar values (strings, numbers, booleans), then applies ILIKE matching.
+
+### Changes
+
+#### secrets-core
+
+**`crates/secrets-core/src/service/search.rs`**
+
+- Add `metadata_query: Option<&'a str>` field to `SearchParams`
+- In `entry_where_clause_and_next_idx`, when `metadata_query` is set, add:
+
+```sql
+EXISTS (
+  SELECT 1 FROM jsonb_path_query(
+    entries.metadata,
+    'strict $.** ? (@.type() != "object" && @.type() != "array")'
+  ) AS val
+  WHERE (val#>>'{}') ILIKE $N ESCAPE '\'
+)
+```
+
+- Bind `ilike_pattern(metadata_query)` at the correct `$N` position in both `fetch_entries_paged` and `count_entries`
+
+#### secrets-mcp (MCP tools)
+
+**`crates/secrets-mcp/src/tools.rs`**
+
+- Add `metadata_query` field to `FindInput`:
+
+```rust
+#[schemars(description = "Fuzzy search across metadata values only (keys excluded)")]
+metadata_query: Option<String>,
+```
+
+- Add same field to `SearchInput`
+- Pass `metadata_query` through to `SearchParams` in both `secrets_find` and `secrets_search` handlers
+
+#### secrets-mcp (Web)
+
+**`crates/secrets-mcp/src/web/entries.rs`**
+
+- Add `metadata_query: Option<String>` to `EntriesQuery`
+- Thread it into all `SearchParams` usages (count, list, folder counts)
+- Pass it into template context
+- Add `metadata_query` to `EntriesPageTemplate` and filter form hidden fields
+- Include `metadata_query` in pagination `href` links
+
+**`crates/secrets-mcp/templates/entries.html`**
+
+- Add a "metadata 值" text input to the filter bar (after name, before type)
+- Preserve value in the input on re-render
+
+### i18n Keys
+
+| Key | zh | zh-Hant | en |
+|-----|-----|---------|-----|
+| `filterMetaLabel` | 元数据值 | 元数据值 | Metadata value |
+| `filterMetaPlaceholder` | 搜索元数据值 | 搜尋元資料值 | Search metadata values |
+
+### Performance Notes
+
+- The `jsonb_path_query` with `$.**` scans all nested values recursively; this is a sequential scan on the metadata column per row
+- The existing GIN index on `metadata jsonb_path_ops` supports `@>` containment queries but NOT this pattern
+- For production datasets > 10k entries, consider a generated column or materialized search column in a future iteration
+- First version prioritizes semantic correctness over index optimization
+
+---
+
+## Feature 2: Entry Relations (DAG)
+
+### Data Model
+
+New table `entry_relations`:
+
+```sql
+CREATE TABLE IF NOT EXISTS entry_relations (
+    parent_entry_id UUID NOT NULL REFERENCES entries(id) ON DELETE CASCADE,
+    child_entry_id  UUID NOT NULL REFERENCES entries(id) ON DELETE CASCADE,
+    created_at      TIMESTAMPTZ NOT NULL DEFAULT NOW(),
+    PRIMARY KEY (parent_entry_id, child_entry_id),
+    CHECK (parent_entry_id <> child_entry_id)
+);
+
+CREATE INDEX idx_entry_relations_parent ON entry_relations(parent_entry_id);
+CREATE INDEX idx_entry_relations_child  ON entry_relations(child_entry_id);
+
+-- Enforce multi-tenant isolation: parent and child must belong to same user
+ALTER TABLE entry_relations ADD CONSTRAINT fk_parent_user
+    FOREIGN KEY (parent_entry_id) REFERENCES entries(id) ON DELETE CASCADE;
+ALTER TABLE entry_relations ADD CONSTRAINT fk_child_user
+    FOREIGN KEY (child_entry_id)  REFERENCES entries(id) ON DELETE CASCADE;
+```
+
+Shared secrets already use `entry_secrets` as an N:N relation, so this is consistent with the existing pattern.
+
+### Cycle Detection
+
+On every `INSERT INTO entry_relations(parent, child)`, check that no path exists from `child` back to `parent`:
+
+```sql
+-- Returns true if adding (parent, child) would create a cycle
+SELECT EXISTS(
+  SELECT 1 FROM entry_relations
+  WHERE child_entry_id = $1   -- $1 = proposed parent
+  START WITH parent_entry_id = $2   -- $2 = proposed child
+  CONNECT BY PRIOR child_entry_id = parent_entry_id
+);
+```
+
+Wait — PostgreSQL doesn't support `START WITH ... CONNECT BY`. Use recursive CTE instead:
+
+```sql
+WITH RECURSIVE chain AS (
+  SELECT parent_entry_id AS ancestor
+  FROM entry_relations
+  WHERE child_entry_id = $1   -- proposed child
+  UNION ALL
+  SELECT er.parent_entry_id
+  FROM entry_relations er
+  JOIN chain c ON c.ancestor = er.child_entry_id
+)
+SELECT EXISTS(SELECT 1 FROM chain WHERE ancestor = $2);
+-- $1 = proposed child, $2 = proposed parent
+```
+
+If `EXISTS` returns true, reject with `AppError::Validation { message: "cycle detected" }`.
+
+### secrets-core Changes
+
+**New file: `crates/secrets-core/src/service/relations.rs`**
+
+```rust
+pub struct RelationSummary {
+    pub parent_id: Uuid,
+    pub parent_name: String,
+    pub parent_folder: String,
+    pub parent_type: String,
+}
+
+pub struct AddRelationParams<'a> {
+    pub parent_entry_id: Uuid,
+    pub child_entry_id: Uuid,
+    pub user_id: Option<Uuid>,
+}
+
+pub struct RemoveRelationParams<'a> {
+    pub parent_entry_id: Uuid,
+    pub child_entry_id: Uuid,
+    pub user_id: Option<Uuid>,
+}
+
+/// Add a parent→child relation. Validates:
+/// - Both entries exist and belong to the same user
+/// - No self-reference (enforced by CHECK constraint)
+/// - No cycle (recursive CTE check)
+pub async fn add_relation(pool: &PgPool, params: AddRelationParams<'_>) -> Result<()>
+
+/// Remove a parent→child relation.
+pub async fn remove_relation(pool: &PgPool, params: RemoveRelationParams<'_>) -> Result<()>
+
+/// Get all parents of an entry (with summary info).
+pub async fn get_parents(pool: &PgPool, entry_id: Uuid, user_id: Option<Uuid>) -> Result<Vec<RelationSummary>>
+
+/// Get all children of an entry (with summary info).
+pub async fn get_children(pool: &PgPool, entry_id: Uuid, user_id: Option<Uuid>) -> Result<Vec<RelationSummary>>
+
+/// Get parents + children for a batch of entry IDs (for list pages).
+pub async fn get_relations_for_entries(
+    pool: &PgPool,
+    entry_ids: &[Uuid],
+    user_id: Option<Uuid>,
+) -> Result<HashMap<Uuid, Vec<RelationSummary>>>
+```
+
+**`crates/secrets-core/src/service/mod.rs`** — add `pub mod relations;`
+
+**`crates/secrets-core/src/db.rs`** — add entry_relations table creation in `migrate()`
+
+**`crates/secrets-core/src/error.rs`** — no new error variant needed; use `AppError::Validation { message }` for cycle detection and permission errors
+
+### MCP Tool Changes
+
+**`crates/secrets-mcp/src/tools.rs`**
+
+1. **`secrets_add`** (`AddInput`): add optional `parent_ids: Option<Vec<String>>` field
+   - Description: "UUIDs of parent entries to link. Creates parent→child relations."
+   - After creating the entry, call `relations::add_relation` for each parent
+
+2. **`secrets_update`** (`UpdateInput`): add two fields:
+   - `add_parent_ids: Option<Vec<String>>` — "UUIDs of parent entries to link"
+   - `remove_parent_ids: Option<Vec<String>>` — "UUIDs of parent entries to unlink"
+
+3. **`secrets_find`** and `secrets_search` output: add `parents` and `children` arrays to each entry result:
+   ```json
+   {
+     "id": "...",
+     "name": "...",
+     "parents": [{"id": "...", "name": "...", "folder": "...", "type": "..."}],
+     "children": [{"id": "...", "name": "...", "folder": "...", "type": "..."}]
+   }
+   ```
+   - Fetch relations for all returned entry IDs in a single batch query
+
+### Web Changes
+
+**`crates/secrets-mcp/src/web/entries.rs`**
+
+1. **New API endpoints:**
+
+   - `POST /api/entries/{id}/relations` — add parent relation
+     - Body: `{ "parent_id": "uuid" }`
+     - Validates same-user ownership and cycle detection
+
+   - `DELETE /api/entries/{id}/relations/{parent_id}` — remove parent relation
+
+   - `GET /api/entries/options?q=xxx` — lightweight search for parent selection modal
+     - Returns `[{ "id": "...", "name": "...", "folder": "...", "type": "..." }]`
+     - Used by the edit dialog's parent selection autocomplete
+
+2. **Entry list template data** — include parent/child counts per entry row
+
+3. **`api_entry_patch`** — extend `EntryPatchBody` with optional `parent_ids: Option<Vec<Uuid>>`
+   - When present, replace all parent relations for this entry with the given list
+   - This is simpler than incremental add/remove in the Web UI context
+
+**`crates/secrets-mcp/templates/entries.html`**
+
+1. **List table**: add a "关联" (relations) column showing parent/child counts as clickable chips
+2. **Edit dialog**: add "上级条目" (parent entries) section
+   - Show current parents as removable chips
+   - Add a search-as-you-type input that queries `/api/entries/options`
+   - Click a search result to add it as parent
+   - On save, send `parent_ids` in the PATCH body
+3. **View dialog / detail**: show "下级条目" (children) list with clickable links that navigate to the child entry
+4. **i18n**: add keys for all new UI elements
+
+### i18n Keys (Entry Relations)
+
+| Key | zh | zh-Hant | en |
+|-----|-----|---------|-----|
+| `colRelations` | 关联 | 關聯 | Relations |
+| `parentEntriesLabel` | 上级条目 | 上級條目 | Parent entries |
+| `childrenEntriesLabel` | 下级条目 | 下級條目 | Child entries |
+| `addParentLabel` | 添加上级 | 新增上級 | Add parent |
+| `removeParentLabel` | 移除上级 | 移除上級 | Remove parent |
+| `searchEntriesPlaceholder` | 搜索条目… | 搜尋條目… | Search entries… |
+| `noParents` | 无上级 | 無上級 | No parents |
+| `noChildren` | 无下级 | 無下級 | No children |
+| `relationCycleError` | 无法添加：会形成循环引用 | 無法新增：會形成循環引用 | Cannot add: would create a cycle |
+
+### Audit Logging
+
+Log relation changes in the existing `audit::log_tx` system:
+
+- Action: `"add_relation"` / `"remove_relation"`
+- Detail JSON: `{ "parent_id": "...", "parent_name": "...", "child_id": "...", "child_name": "..." }`
+
+### Export / Import
+
+**`ExportEntry`** — add optional `parents: Vec<ParentRef>` where:
+
+```rust
+pub struct ParentRef {
+    pub folder: String,
+    pub name: String,
+}
+```
+
+- On export, resolve each entry's parent IDs to `(folder, name)` pairs
+- On import, two-phase:
+  1. Create all entries (skip parents)
+  2. For each entry with `parents`, resolve `(folder, name)` → `entry_id` and call `add_relation`
+  3. If a parent reference cannot be resolved, log a warning and skip it (don't fail the entire import)
+
+### History / Rollback
+
+- Relation changes are **not** versioned in `entries_history`. They are tracked only via `audit_log`.
+- Rationale: relations are a cross-entry concern; rolling them back alongside entry fields would require complex multi-entry coordination. The audit log provides sufficient traceability.
+- If the user explicitly requests rollback of relations in the future, it can be implemented as a separate feature.
+
+---
+
+## Implementation Order
+
+### Phase 1: Metadata Value Search
+
+1. `secrets-core/src/service/search.rs` — add `metadata_query` to `SearchParams`, implement SQL condition
+2. `secrets-mcp/src/tools.rs` — add `metadata_query` to `FindInput` and `SearchInput`, wire through
+3. `secrets-mcp/src/web/entries.rs` — add `metadata_query` to `EntriesQuery`, `SearchParams`, pagination, folder counts
+4. `secrets-mcp/templates/entries.html` — add input field, i18n
+5. Test: existing `query` still works; `metadata_query` only matches values
+
+### Phase 2: Entry Relations (Core)
+
+1. `secrets-core/src/db.rs` — add `entry_relations` table to `migrate()`
+2. `secrets-core/src/service/relations.rs` — implement `add_relation`, `remove_relation`, `get_parents`, `get_children`, `get_relations_for_entries`, cycle detection
+3. `secrets-core/src/service/mod.rs` — add `pub mod relations`
+4. Test: add/remove/query relations, cycle detection, same-user validation
+
+### Phase 3: Entry Relations (MCP)
+
+1. `secrets-mcp/src/tools.rs` — extend `AddInput`, `UpdateInput` with parent IDs
+2. `secrets-mcp/src/tools.rs` — extend `secrets_find`/`secrets_search` output with `parents`/`children`
+3. Test: MCP tools work end-to-end
+
+### Phase 4: Entry Relations (Web)
+
+1. `secrets-mcp/src/web/entries.rs` — add API endpoints, extend `EntryPatchBody`, extend template data
+2. `secrets-mcp/templates/entries.html` — add relations column, edit dialog parent selector, view dialog children list
+3. Test: Web UI works end-to-end
+
+### Phase 5: Export / Import (Optional)
+
+1. `secrets-core/src/models.rs` — add `parents` to `ExportEntry`
+2. `secrets-core/src/service/export.rs` — populate parents
+3. `secrets-core/src/service/import.rs` — two-phase import with relation resolution
+
+---
+
+## Database Migration
+
+Add to `secrets-core/src/db.rs` `migrate()`:
+
+```sql
+CREATE TABLE IF NOT EXISTS entry_relations (
+    parent_entry_id UUID NOT NULL REFERENCES entries(id) ON DELETE CASCADE,
+    child_entry_id  UUID NOT NULL REFERENCES entries(id) ON DELETE CASCADE,
+    created_at      TIMESTAMPTZ NOT NULL DEFAULT NOW(),
+    PRIMARY KEY (parent_entry_id, child_entry_id),
+    CHECK (parent_entry_id <> child_entry_id)
+);
+
+CREATE INDEX IF NOT EXISTS idx_entry_relations_parent ON entry_relations(parent_entry_id);
+CREATE INDEX IF NOT EXISTS idx_entry_relations_child  ON entry_relations(child_entry_id);
+```
+
+This is idempotent (uses `IF NOT EXISTS`) and will run automatically on next startup.
+
+---
+
+## Security Considerations
+
+- **Same-user isolation**: `add_relation` must verify both `parent_entry_id` and `child_entry_id` belong to the same `user_id` (or both are `NULL` for legacy single-user mode)
+- **Cycle detection**: Recursive CTE query prevents any directed cycle, regardless of depth
+- **CASCADE delete**: When an entry is deleted, all its relation edges are automatically removed via the `ON DELETE CASCADE` foreign key. This is the same pattern used by `entry_secrets`.
+
+---
+
+## Testing Checklist
+
+### Metadata Search
+- [ ] `metadata_query=1.2.3.4` matches entries where any metadata value contains "1.2.3.4"
+- [ ] `metadata_query=1.2.3.4` does NOT match entries where only the key contains "1.2.3.4"
+- [ ] `metadata_query` works with nested metadata (e.g. `{"server": {"ip": "1.2.3.4"}}`)
+- [ ] `metadata_query` combined with `folder`/`type`/`tags` filters works correctly
+- [ ] `metadata_query` with special characters (`%`, `_`) is properly escaped
+- [ ] Existing `query` parameter behavior is unchanged
+- [ ] Web filter bar preserves `metadata_query` across pagination and folder tab clicks
+
+### Entry Relations
+- [ ] Can add a parent→child relation between two entries
+- [ ] Can add multiple parents to a single entry
+- [ ] Cannot add self-referencing relation (CHECK constraint)
+- [ ] Cannot create a direct cycle (A→B→A)
+- [ ] Cannot create an indirect cycle (A→B→C→A)
+- [ ] Cannot link entries from different users
+- [ ] Deleting an entry removes all its relation edges but leaves related entries intact
+- [ ] MCP `secrets_add` with `parent_ids` creates relations
+- [ ] MCP `secrets_update` with `add_parent_ids`/`remove_parent_ids` modifies relations
+- [ ] MCP `secrets_find`/`secrets_search` output includes `parents` and `children`
+- [ ] Web entry list shows relation counts
+- [ ] Web edit dialog allows adding/removing parents
+- [ ] Web entry view shows children with navigation links
