+
+### 1. URL Updates
+
+Changed in multiple snippets:
+
+| Old URL | New URL |
+|---------|---------|
+| `https://m5api.momentry.ddns.net` | `http://192.168.110.201:3002` |
+| `https://api.momentry.ddns.net` | `http://192.168.110.201:3002` |

+
+Affected snippets: #37, #43, #44, #48, #55, #59, #60, #61, #62, #63, #64, #66, #67
+
+### 2. Snippet #66 Fixes
+
+**Before (syntax error)**:
+```php
+$body = [
+ . 'query'     => $query,   // ❌ Invalid PHP syntax
+ . 'limit'     => 20,
+];
+```
+
+**After (fixed)**:
+```php
+// Semantic search body
+$body = [
+  'query'     => $query,
+  'limit'     => 20,
+  'page'      => 1,
+  'page_size' => 20,
+];
+
+// Universal search body
+$body = [
+  'query'     => $query,
+  'limit'     => 20,
+  'page'      => 1,
+  'page_size' => 20,
+];
+```
+
+Note: `file_uuid` was NOT added per user request.
+
+## Backup Location
+
+```
+/Users/accusys/momentry_core/backups/wp_snippets_20260529_181847/
+```
+
+Contains:
+- `wp_snippets_full.sql` - Full backup before any changes
+- `snippets_with_old_url.sql` - Snippets containing old URLs
+- `snippets_43_44_48_54_before_api_fix.sql`
+- `snippet_66_before_syntax_fix.sql`
+
+## Restore Command
+
+```bash
+mysql -u wp_user -p'wp_password_123' wordpress < /Users/accusys/momentry_core/backups/wp_snippets_20260529_181847/wp_snippets_full.sql
+```
+
+## Pending Issue: Semantic/Keyword Search Returns Empty
+
+### Symptoms
+
+- Direct API call to momentry_core: Returns results
+- WP proxy call: Returns `{"results": [], "total": 0}`
+
+### Direct API Test (Works)
+
+```bash
+curl -s http://192.168.110.201:3002/api/v1/search/smart \
+  -H 'Content-Type: application/json' \
+  -H 'X-API-Key: muser_68600856036340bcafc01930eb4bd839_1774418104_97221b69' \
+  -d '{"query":"love","limit":20,"page":1,"page_size":20}'
+# Returns 20 results
+```
+
+### WP Proxy Test (Empty)
+
+```bash
+curl -sk 'https://m5wp.momentry.ddns.net/wp-json/momentry/v1/search-proxy?mode=semantic&query=love'
+# Returns {"query":"love","results":[],"page":1,"page_size":20,"strategy":"semantic_vector_search"}
+```
+
+### Hypothesis
+
+1. WordPress `wp_remote_request` may encode JSON differently
+2. Header mismatch between WordPress and curl
+3. PHP `$body` array construction issue
+
+### Debug Steps Needed
+
+1. Add debug output to snippet to return the exact `$body` JSON being sent
+2. Check WordPress HTTP request logs
+3. Compare raw request payload from WordPress vs curl
+
+### Temporary Workaround
+
+Use people search (works) or call momentry_core directly from frontend bypassing WP proxy.
