+# Fix: Conflicting `[Reference]` vs `[ReferenceDetail]` in RepositorySettingsView
+
+## Background
+
+`RepositoryDetailViewModel.branches` was recently changed from `[Reference]` to
+`[ReferenceDetail]` to support displaying commit dates in the Refs tab.
+`ReferenceDetail` has the same `name: String` and `target: String?` fields as
+`Reference`, plus an additional `date: Date?`.
+
+`RepositorySettingsView` and `RepositorySettingsViewModel` still declare their
+`branches` parameter as `[Reference]`, causing this compiler error:
+
+```
+RepositoryDetailView.swift:56:51
+Conflicting arguments to generic parameter 'T' ('[ReferenceDetail]' vs. '[Reference]')
+```
+
+The settings view model only uses `branches` for the HEAD branch picker
+(`selectedHeadReferenceForSave()` accesses `$0.name`). No mapping back to
+`Reference` is needed — just update the type throughout the settings layer.
+
+---
+
+## Changes Required
+
+### 1. `Hutch/Views/Repositories/RepositorySettingsViewModel.swift`
+
+**Change the stored property type:**
+
+Find:
+```swift
+var branches: [Reference]
+```
+
+Replace with:
+```swift
+var branches: [ReferenceDetail]
+```
+
+**Change the `init` parameter type:**
+
+Find:
+```swift
+init(
+    repository: RepositorySummary,
+    branches: [Reference],
+    client: SRHTClient
+) {
+```
+
+Replace with:
+```swift
+init(
+    repository: RepositorySummary,
+    branches: [ReferenceDetail],
+    client: SRHTClient
+) {
+```
+
+### 2. `Hutch/Views/Repositories/RepositorySettingsView.swift`
+
+**Change the stored property type:**
+
+Find:
+```swift
+let branches: [Reference]
+```
+
+Replace with:
+```swift
+let branches: [ReferenceDetail]
+```
+
+---
+
+## No Other Changes
+
+- Do not modify `Reference` or `ReferenceDetail` in `Git.swift`.
+- Do not modify `RepositoryDetailView.swift` — the call site is already correct.
+- Do not modify `ReferencesListView.swift` or `RepositoryDetailViewModel.swift`.
+- `selectedHeadReferenceForSave()` in the settings view model accesses only
+  `$0.name` on each branch, which exists on `ReferenceDetail` — no logic
+  changes are needed.
+
+## Verification
+
+Build the project. The compiler error at `RepositoryDetailView.swift:56` should
+be gone. Confirm the repository settings sheet still opens and the HEAD branch
+picker populates correctly.
