+# Replacement rules for syncing rees46/flutter-sdk -> personaclick/flutter-sdk.
+# Consumed by rees46/workflow/.github/actions/sync/read-replacements (replacementsRepo: rees46/workflow)
+# and applied by @scripts/repo-replacement (renames paths + file contents, then deletions).
+#
+# Order matters: the api-domain rule must run BEFORE the generic "rees46" rule,
+# otherwise "api.rees46.ru" would become "api.personaclick.ru" (wrong TLD).
+replacements:
+  - from: "api.rees46.ru"
+    to: "api.personaclick.com"
+  - from: "REES46"
+    to: "PERSONACLICK"
+  - from: "Rees46"
+    to: "Personaclick"
+  - from: "rees46"
+    to: "personaclick"
+  # pub.dev package names are globally unique — the mirror must publish under a
+  # distinct name. Renames the package id + import paths + barrel file + podspec,
+  # without touching the internal `PersonalizationSdk` class / personalization_sdk.dart.
+  - from: "personalization_flutter_sdk"
+    to: "personaclick_flutter_sdk"
+
+# rees46-Firebase-project files: tied to project "rees46-com" / package com.rees46.* —
+# invalid in the personaclick mirror, which must provide its own Firebase config.
+# The source sync workflow itself must not be mirrored into the target.

+  - .github/workflows/sync.yaml

+# .github IS mirrored and renamed; the source sync.yaml is stripped via `deletions`.
