 **Frontend template** (`id_index.etlua`) можливо потребує adjustment коли backend exposes `mysettings.cur_archive_path` чи similar — depending on app.lua implementation.

+## D-canonical-archive-regression — REGRESSION у нових `getLinks()` (~20 sites)
+
+**Update 2026-05-05:** Audit deeper показав що це **regression**, не intended config.
+
+**Reference (correct behavior — pre-batch sites):**
+- broxxx.com (8133), pornv.xxx (8120): same `var.canonical_without_archive=1`, але archive route → `getLinks()` повертає `cur_canonical=""` → layout skip emit → **no canonical on archive** ✓
+- Це matching intent variable name "canonical_without_archive" = "canonical видається без archive context, тобто на archive не emit-иться".
+
+**Bug (regression — newer sites):**
+- 8161, 8159, 8163, 8158, 8151, 8152, 8153, 8154, 8155, 8156, 8157, 8158, 8160, 8162, 8140, 8141, 8142, 8145, 8148, 8149: same config `=1`, але archive route → `cur_canonical=<standard URL stripped>` → canonical EMITS до /v/.
+- Це over-engineered — backend strips archive prefix замість returning empty.
+
+**Scope:** ~20 sites with newer code version. Different `getLinks()` implementations у `lib/<port>/content.lua`.
+
+**Fix (backend dev task):**
+- Identify які content.lua versions мають regression.
+- Patch `getLinks()` to return `cur_canonical=""` when `canonical_without_archive=1` AND archive route.
+- Match broxxx/pornv behavior (старий правильний reference).
+- kor reboot per site.
+
+**Verify:** після fix на archive URL — `<link rel="canonical">` має бути absent (як у broxxx/pornv).
