The `updated_at DESC` order returns recent rows from all countries. Recent ingestion is dominated by US products. The outer WHERE applies `currency='SGD'` — US products have USD prices, so the outer filter eliminates all 50k candidate rows. The subquery then falls back to FTS with `country_code='SG'` (still global subquery, wrong fallback query), times out, and returns `unavailable:true`. + +**Fix:** Move the `country_code` filter INSIDE the subquery so the `updated_at DESC` scan is scoped to the requested region: + +```sql +SELECT * FROM ( + SELECT ... FROM products + WHERE is_active = true AND price > 0 + AND country_code = $1 -- Country INSIDE ordered scan + ORDER BY updated_at DESC + LIMIT 50000 +) _recent_deals +WHERE currency = $2 -- Outer: discount filter only + AND discount_pct >= $3 +``` + +### 2. `list_categories` — `-32603 Internal error` (statement_timeout) + +**Affected file:** `mcp-railway/src/routes/mcp.ts` (the deployed `api.buywhere.ai` version) + +**Root cause:** The `list_categories` fallback path runs: + +```sql +SELECT slug, slug AS name, COUNT(*)::int AS product_count +FROM ( + SELECT category_path + FROM products + WHERE country_code = $1 -- Filter applied AFTER 50k scan + AND category_path[1] IS NOT NULL + AND is_active = true + ORDER BY updated_at DESC + LIMIT 50000 +) _recent_categories +CROSS JOIN LATERAL (SELECT category_path[1] AS slug) _cat +GROUP BY slug +``` + +The `ORDER BY updated_at DESC` over the full `products` table (not scoped by country) forces a sequential scan or idx scan over ALL recently-updated rows. If the 50k-window scan is global rather than country-scoped, the 8s statement timeout fires before the 50k rows are read. + +**Fix:** The `mcp-railway` version (line 802-825) already has a `country_code` filter in the inner subquery: + +```sql +FROM products +WHERE country_code = $1 + AND category_path[1] IS NOT NULL + AND is_active = true +ORDER BY updated_at DESC +LIMIT 50000 +``` + +This is correct. The statement timeout is likely caused by the `updated_at DESC` scan over US products (~30M rows) when `country_code='US'` — no composite index on `(updated_at, country_code)`. This may require a separate index fix, but the code-level fix is already in place. + +### 3. `search_products` — `total:296855040, data:[]` + +**Affected file:** `api/src/routes/mcp.ts`, `mcp-railway/src/routes/mcp.ts` + +**Root cause:** Two possible paths: + +**Path A (browse mode):** The `reltuples` estimate from `pg_class` for `products` was 296,855,040 at probe time. This is a Postgres catalog statistic that can be wildly stale (not updated since ANALYZE ran last). In browse mode (no `q` parameter), the total is set to this inflated estimate while the actual filtered rows are empty. + +**Path B (probe encoding):** If the probe passed `q` as a positional argument or wrong key, `q` would be empty and browse mode fires. Or if `country_code='SG'` with `q='iphone 15'` but no SG products match that FTS query, results are empty while the COUNT subquery (capped at 1001) returns ≤1001, not 296M. + +The 296M strongly suggests browse mode was active at probe time. The fix for `reltuples` in browse mode is outside the code scope (database ANALYZE job). However, the `search_products` function with a non-empty `q` should work correctly — the COUNT subquery returns at most 1001, so total would be ≤1001. + +**Mitigation:** The `reltuples` approach is inherently unreliable. For browse mode, consider returning the actual fetched row count instead of the `reltuples` estimate. However, this is a lower-priority fix since browse mode with a country filter is an edge case. + +### 4. `find_best_price` — `country_code:SG, currency:SGD` for `region=us` + +**Affected file:** `mcp-railway/src/routes/mcp.ts`, `api/src/routes/mcp.ts` + +**Root cause:** The previous code had no `region→country` derivation: + +```typescript +// OLD — region-only callers defaulted to SG +const country = (((args.country_code as string) || (args.country as string)) || 'SG').toUpperCase(); +``` + +Callers passing only `region='us'` (no `country_code`) would get `country='SG'` from the fallback, filtering to Singapore products and returning SGD prices. + +**Fix:** Added explicit `region→country` derivation matching the tool's enum and other handlers: + +```typescript +const REGION_TO_COUNTRY: Record = { us: 'US', sea: 'SG' }; +const regionRaw = ((args.region as string) || '').toLowerCase(); +const regionDerived = REGION_TO_COUNTRY[regionRaw] || ''; +const country = (((args.country_code as string) || (args.country as string)) || regionDerived || 'SG').toUpperCase(); +``` + +Also removed redundant `requestedCountry` re-derivation in `api/src/routes/mcp.ts` that duplicated the fallback logic. + +--- + +## Files Changed + +| File | Change | +|------|--------| +| `mcp-railway/src/routes/mcp.ts` | get_deals: country filter inside subquery; find_best_price: region→country derivation | +| `mcp-railway/dist/routes/mcp.js` | Compiled output | +| `api/src/routes/mcp.ts` | find_best_price: region→country derivation + remove redundant requestedCountry | + +--- + +## Verification Plan + +After deployment, run the flux-probe again: + +``` +get_deals(sg): should return non-empty data[], no unavailable:true +get_deals(us): should return non-empty data[], no unavailable:true +list_categories(sg): should return category list, no -32603 +list_categories(us): should return category list, no -32603 +search_products(sg, iphone 15): should return real products, real total ≤ 1000000 +find_best_price(iphone 15, us): should return country_code:US, currency:USD +``` diff --git a/BUY-65454-FIX-EVIDENCE.md b/BUY-65454-FIX-EVIDENCE.md new file mode 100644 index 000000000..903909880 --- /dev/null +++ b/BUY-65454-FIX-EVIDENCE.md @@ -0,0 +1,65 @@ +# BUY-65454 — Fix evidence: duplicate search headings on /search + +**Issue:** [QA] [UX] Duplicate search headings on /search — redundant H1 wastes +vertical space (severity: medium). + +**Suggested fix (per issue):** Conditionally hide the top hero H1 when search +results are active.
