-name: Widget decomposition and provider subscriptions
-description: Prefer splitting screens into multiple focused files/widgets; each widget subscribes to its own relevant providers
-type: feedback
----
-
-Split screens into multiple smaller widgets across multiple files. Each widget should subscribe only to the providers it needs (`ref.watch` at lowest possible level), rather than having one large screen widget that watches everything and passes data down as parameters.
-
-**Why:** Reduces unnecessary rebuilds; improves readability; each file has one clear responsibility.
-
-**How to apply:** When building a new screen, identify which sub-widgets need their own provider subscriptions and extract them into separate files (e.g., `widgets/grant_card.dart` watches enrichment providers itself, rather than the screen doing it and passing resolved strings down).

-# Grant Grid View Implementation Plan
-
-> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
-
-**Goal:** Add an "EVM Grants" dashboard tab that displays all grants as enriched cards (type, chain, wallet address, client name) with per-card revoke support.
-
-**Architecture:** A new `walletAccessListProvider` fetches wallet accesses with their DB row IDs. The screen (`grants.dart`) watches only `evmGrantsProvider` for top-level state. Each `GrantCard` widget (its own file) watches enrichment providers (`walletAccessListProvider`, `evmProvider`, `sdkClientsProvider`) and the revoke mutation directly — keeping rebuilds scoped to the card. The screen is registered as a dashboard tab in `AdaptiveScaffold`.
-
-**Tech Stack:** Flutter, Riverpod (`riverpod_annotation` + `build_runner` codegen), `sizer` (adaptive sizing), `auto_route`, Protocol Buffers (Dart), `Palette` design tokens.

-## File Map
-
-| File | Action | Responsibility |
-|---|---|---|
-| `useragent/lib/theme/palette.dart` | Modify | Add `Palette.token` (indigo accent for token-transfer cards) |

-## Task 1: Add `Palette.token`
-
-**Files:**
-- Modify: `useragent/lib/theme/palette.dart`
-
-- [ ] **Step 1: Add the color**
-
-Replace the contents of `useragent/lib/theme/palette.dart` with:
-
-```dart
-import 'package:flutter/material.dart';
-
-class Palette {
-  static const ink = Color(0xFF15263C);
-  static const coral = Color(0xFFE26254);
-  static const cream = Color(0xFFFFFAF4);
-  static const line = Color(0x1A15263C);
-  static const token = Color(0xFF5C6BC0);
-}
-```
-
-- [ ] **Step 2: Verify**
-
-```sh
-cd useragent && flutter analyze lib/theme/palette.dart
-```
-
-Expected: no issues.
-
-- [ ] **Step 3: Commit**
-
-```sh
-jj describe -m "feat(theme): add Palette.token for token-transfer grant cards"
-jj new
-```
-

-
-## Task 2: Add `listAllWalletAccesses` feature function
-
-**Files:**
-- Modify: `useragent/lib/features/connection/evm/wallet_access.dart`
-
-`readClientWalletAccess` (existing) filters the list to one client's wallet IDs and returns `Set<int>`. This new function returns the complete unfiltered list with row IDs so the grant cards can resolve wallet_access_id → wallet + client.
-
-- [ ] **Step 1: Append function**
-
-Add at the bottom of `useragent/lib/features/connection/evm/wallet_access.dart`:
-
-```dart
-Future<List<SdkClientWalletAccess>> listAllWalletAccesses(
-  Connection connection,
-) async {
-  final response = await connection.ask(
-    UserAgentRequest(listWalletAccess: Empty()),
-  );
-  if (!response.hasListWalletAccessResponse()) {
-    throw Exception(
-      'Expected list wallet access response, got ${response.whichPayload()}',
-    );
-  }
-  return response.listWalletAccessResponse.accesses.toList(growable: false);
-}
-```
-
-Each returned `SdkClientWalletAccess` has:
-- `.id` — the `evm_wallet_access` row ID (same value as `wallet_access_id` in a `GrantEntry`)
-- `.access.walletId` — the EVM wallet DB ID
-- `.access.sdkClientId` — the SDK client DB ID
-
-- [ ] **Step 2: Verify**
-
-```sh
-cd useragent && flutter analyze lib/features/connection/evm/wallet_access.dart
-```
-
-Expected: no issues.
-
-- [ ] **Step 3: Commit**
-
-```sh
-jj describe -m "feat(evm): add listAllWalletAccesses feature function"
-jj new

-## Task 3: Create `WalletAccessListProvider`
-
-**Files:**
-- Create: `useragent/lib/providers/sdk_clients/wallet_access_list.dart`
-- Generated: `useragent/lib/providers/sdk_clients/wallet_access_list.g.dart`
-
-Mirrors the structure of `EvmGrants` in `providers/evm/evm_grants.dart` — class-based `@riverpod` with a `refresh()` method.
-
-- [ ] **Step 1: Write the provider**
-
-Create `useragent/lib/providers/sdk_clients/wallet_access_list.dart`:
-
-```dart
-import 'package:arbiter/features/connection/evm/wallet_access.dart';
-import 'package:arbiter/proto/user_agent.pb.dart';
-import 'package:arbiter/providers/connection/connection_manager.dart';
-import 'package:mtcore/markettakers.dart';
-import 'package:riverpod_annotation/riverpod_annotation.dart';
-
-part 'wallet_access_list.g.dart';
-
-@riverpod
-class WalletAccessList extends _$WalletAccessList {
-  @override
-  Future<List<SdkClientWalletAccess>?> build() async {
-    final connection = await ref.watch(connectionManagerProvider.future);
-    if (connection == null) {
-      return null;
-    }
-
-    try {
-      return await listAllWalletAccesses(connection);
-    } catch (e, st) {
-      talker.handle(e, st);
-      rethrow;
-    }
-  }
-
-  Future<void> refresh() async {
-    final connection = await ref.read(connectionManagerProvider.future);
-    if (connection == null) {
-      state = const AsyncData(null);
-      return;
-    }
-
-    state = const AsyncLoading();
-    state = await AsyncValue.guard(() => listAllWalletAccesses(connection));
-  }
-}
-```
-
-- [ ] **Step 2: Run code generation**
-
-```sh
-cd useragent && dart run build_runner build --delete-conflicting-outputs
-```
-
-Expected: `useragent/lib/providers/sdk_clients/wallet_access_list.g.dart` created. No errors.
-
-- [ ] **Step 3: Verify**
-
-```sh
-cd useragent && flutter analyze lib/providers/sdk_clients/

-## Task 4: Create `GrantCard` widget
-
-**Files:**
-- Create: `useragent/lib/screens/dashboard/evm/grants/widgets/grant_card.dart`
-
-This widget owns all per-card logic: enrichment lookups, revoke action, and rebuild scope. The screen only passes it a `GrantEntry` — the card fetches everything else itself.
-
-**Key types:**
-- `GrantEntry` (from `proto/evm.pb.dart`): `.id`, `.shared.walletAccessId`, `.shared.chainId`, `.specific.whichGrant()`
-- `SpecificGrant_Grant.etherTransfer` / `.tokenTransfer` — enum values for the oneof
-- `SdkClientWalletAccess` (from `proto/user_agent.pb.dart`): `.id`, `.access.walletId`, `.access.sdkClientId`
-- `WalletEntry` (from `proto/evm.pb.dart`): `.id`, `.address` (List<int>)
-- `SdkClientEntry` (from `proto/user_agent.pb.dart`): `.id`, `.info.name`
-- `revokeEvmGrantMutation` — `Mutation<void>` (global; all revoke buttons disable together while any revoke is in flight)
-- `executeRevokeEvmGrant(ref, grantId: int)` — `Future<void>`

-## Task 5: Create `EvmGrantsScreen`
-
-**Files:**
-- Create: `useragent/lib/screens/dashboard/evm/grants/grants.dart`
-
-The screen watches only `evmGrantsProvider` for top-level state (loading / error / no connection / empty / data). When there is data it renders a list of `GrantCard` widgets — each card manages its own enrichment subscriptions.
-
-- [ ] **Step 1: Write the screen**

-## Task 6: Wire router and dashboard tab
-
-**Files:**
-- Modify: `useragent/lib/router.dart`
-- Modify: `useragent/lib/screens/dashboard.dart`
-- Regenerated: `useragent/lib/router.gr.dart`
-
-- [ ] **Step 1: Add route to `router.dart`**
-
-Replace the contents of `useragent/lib/router.dart` with:
-
-```dart
-import 'package:auto_route/auto_route.dart';
-
-import 'router.gr.dart';
-
-@AutoRouterConfig(generateForDir: ['lib/screens'])
-class Router extends RootStackRouter {
-  @override
-  List<AutoRoute> get routes => [
-    AutoRoute(page: Bootstrap.page, path: '/bootstrap', initial: true),
-    AutoRoute(page: ServerInfoSetupRoute.page, path: '/server-info'),
-    AutoRoute(page: ServerConnectionRoute.page, path: '/server-connection'),
-    AutoRoute(page: VaultSetupRoute.page, path: '/vault'),
-    AutoRoute(page: ClientDetailsRoute.page, path: '/clients/:clientId'),
-    AutoRoute(page: CreateEvmGrantRoute.page, path: '/evm-grants/create'),

-        AutoRoute(page: AboutRoute.page, path: 'about'),
-      ],
-    ),
-  ];
-}
-```
-
-- [ ] **Step 2: Update `dashboard.dart`**
-
-In `useragent/lib/screens/dashboard.dart`, replace the `routes` constant:
-
-```dart
-final routes = [
-  const EvmRoute(),
-  const ClientsRoute(),
-  const EvmGrantsRoute(),
-  const AboutRoute(),
-];
-```
-
-And replace the `destinations` list inside `AdaptiveScaffold`:
-
-```dart
-destinations: const [
-  NavigationDestination(
-    icon: Icon(Icons.account_balance_wallet_outlined),
-    selectedIcon: Icon(Icons.account_balance_wallet),
-    label: 'Wallets',
-  ),
-  NavigationDestination(
-    icon: Icon(Icons.devices_other_outlined),
-    selectedIcon: Icon(Icons.devices_other),
-    label: 'Clients',
-  ),
-  NavigationDestination(
-    icon: Icon(Icons.policy_outlined),
-    selectedIcon: Icon(Icons.policy),
-    label: 'Grants',

-    icon: Icon(Icons.info_outline),
-    selectedIcon: Icon(Icons.info),
-    label: 'About',
-  ),
-],
-```
-
-- [ ] **Step 3: Regenerate router**
-
-```sh
-cd useragent && dart run build_runner build --delete-conflicting-outputs
-```
-
-Expected: `lib/router.gr.dart` updated, `EvmGrantsRoute` now available, no errors.
-
-- [ ] **Step 4: Full project verify**
-
-```sh
-cd useragent && flutter analyze
-```
-
-Expected: no issues.
-
-- [ ] **Step 5: Commit**

-# Grant Grid View — Design Spec
-
-**Date:** 2026-03-28
-
-## Overview
-
-Add a "Grants" dashboard tab to the Flutter user-agent app that displays all EVM grants as a card-based grid. Each card shows a compact summary (type, chain, wallet address, client name) with a revoke action. The tab integrates into the existing `AdaptiveScaffold` navigation alongside Wallets, Clients, and About.
-
-## Scope
-
-- New `walletAccessListProvider` for fetching wallet access entries with their DB row IDs
-- New `EvmGrantsScreen` as a dashboard tab
-- Grant card widget with enriched display (type, chain, wallet, client)
-- Revoke action wired to existing `executeRevokeEvmGrant` mutation
-- Dashboard tab bar and router updated
-- New token-transfer accent color added to `Palette`
-
-**Out of scope:** Fixing grant creation (separate task).
-
----
-
-## Data Layer
-
-### `walletAccessListProvider`
-
-**File:** `useragent/lib/providers/sdk_clients/wallet_access_list.dart`
-
-- `@riverpod` class, watches `connectionManagerProvider.future`
-- Returns `List<SdkClientWalletAccess>?` (null when not connected)
-- Each entry: `.id` (wallet_access_id), `.access.walletId`, `.access.sdkClientId`
-- Exposes a `refresh()` method following the same pattern as `EvmGrants.refresh()`
-
-### Enrichment at render time (Approach A)
-
-The `EvmGrantsScreen` watches four providers:
-1. `evmGrantsProvider` — the grant list
-2. `walletAccessListProvider` — to resolve wallet_access_id → (wallet_id, sdk_client_id)
-3. `evmProvider` — to resolve wallet_id → wallet address
-4. `sdkClientsProvider` — to resolve sdk_client_id → client name
-
-All lookups are in-memory Maps built inside the build method; no extra model class needed.
-
-Fallbacks:
-- Wallet address not found → `"Access #N"` where N is the wallet_access_id
-- Client name not found → `"Client #N"` where N is the sdk_client_id
-
----
-
-## Route Structure
-
-```
-/dashboard
-  /evm          ← existing (Wallets tab)
-  /clients      ← existing (Clients tab)
-  /grants       ← NEW (Grants tab)
-  /about        ← existing
-
-/evm-grants/create  ← existing push route (unchanged)
-```
-
-### Changes to `router.dart`
-
-Add inside dashboard children:
-```dart
-AutoRoute(page: EvmGrantsRoute.page, path: 'grants'),
-```
-
-### Changes to `dashboard.dart`
-
-Add to `routes` list:
-```dart
-const EvmGrantsRoute()
-```
-
-Add `NavigationDestination`:
-```dart
-NavigationDestination(
-  icon: Icon(Icons.policy_outlined),
-  selectedIcon: Icon(Icons.policy),
-  label: 'Grants',
-),
-```
-
----
-
-## Screen: `EvmGrantsScreen`
-
-**File:** `useragent/lib/screens/dashboard/evm/grants/grants.dart`
-
-```
-Scaffold
-└─ SafeArea
-   └─ RefreshIndicator.adaptive (refreshes evmGrantsProvider + walletAccessListProvider)
-      └─ ListView (BouncingScrollPhysics + AlwaysScrollableScrollPhysics)
-         ├─ PageHeader
-         │    title: 'EVM Grants'
-         │    isBusy: evmGrantsProvider.isLoading
-         │    actions: [CreateGrantButton, RefreshButton]
-         ├─ SizedBox(height: 1.8.h)
-         └─ <content>
-```
-
-### State handling
-
-Matches the pattern from `EvmScreen` and `ClientsScreen`:
-
-| State | Display |
-|---|---|
-| Loading (no data yet) | `_StatePanel` with spinner, "Loading grants" |
-| Error | `_StatePanel` with coral icon, error message, Retry button |
-| No connection | `_StatePanel`, "No active server connection" |
-| Empty list | `_StatePanel`, "No grants yet", with Create Grant shortcut |
-| Data | Column of `_GrantCard` widgets |
-
-### Header actions
-
-**CreateGrantButton:** `FilledButton.icon` with `Icons.add_rounded`, pushes `CreateEvmGrantRoute()` via `context.router.push(...)`.
-
-**RefreshButton:** `OutlinedButton.icon` with `Icons.refresh`, calls `ref.read(evmGrantsProvider.notifier).refresh()`.
-
----
-
-## Grant Card: `_GrantCard`
-
-**Layout:**
-
-```
-Container (rounded 24, Palette.cream bg, Palette.line border)
-└─ IntrinsicHeight > Row
-   ├─ Accent strip (0.8.w wide, full height, rounded left)
-   └─ Padding > Column
-        ├─ Row 1: TypeBadge + ChainChip + Spacer + RevokeButton
-        └─ Row 2: WalletText + "·" + ClientText
-```
-
-**Accent color by grant type:**
-- Ether transfer → `Palette.coral`
-- Token transfer → `Palette.token` (new entry in `Palette` — indigo, e.g. `Color(0xFF5C6BC0)`)
-
-**TypeBadge:** Small pill container with accent color background at 15% opacity, accent-colored text. Label: `'Ether'` or `'Token'`.
-
-**ChainChip:** Small container: `'Chain ${grant.shared.chainId}'`, muted ink color.
-
-**WalletText:** Short hex address (`0xabc...def`) from wallet lookup, `bodySmall`, monospace font family.
-
-**ClientText:** Client name from `sdkClientsProvider` lookup, or fallback string. `bodySmall`, muted ink.
-
-**RevokeButton:**
-- `OutlinedButton` with `Icons.block_rounded` icon, label `'Revoke'`
-- `foregroundColor: Palette.coral`, `side: BorderSide(color: Palette.coral.withValues(alpha: 0.4))`
-- Disabled (replaced with `CircularProgressIndicator`) while `revokeEvmGrantMutation` is pending — note: this is a single global mutation, so all revoke buttons disable while any revoke is in flight
-- On press: calls `executeRevokeEvmGrant(ref, grantId: grant.id)`; shows `SnackBar` on error
-
----
-
-## Adaptive Sizing
-
-All sizing uses `sizer` units (`1.h`, `1.w`, etc.). No hardcoded pixel values.
-
----
-
-## Files to Create / Modify
-
-| File | Action |
-|---|---|
-| `lib/theme/palette.dart` | Modify — add `Palette.token` color |
-| `lib/providers/sdk_clients/wallet_access_list.dart` | Create |
-| `lib/screens/dashboard/evm/grants/grants.dart` | Create |
-| `lib/router.dart` | Modify — add grants route to dashboard children |
-| `lib/screens/dashboard.dart` | Modify — add tab to routes list and NavigationDestinations |

+# Client Wallet Access Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Add a dedicated client details screen under `Clients` where operators can view a client and manage the set of accessible EVM wallets.
+
+**Architecture:** Keep the existing `Clients` list as the entry point and add a focused details route/screen for one `SdkClientEntry`. Use Riverpod providers for the wallet inventory, client-scoped access draft, and save mutation. Because the current proto surface does not expose client-wallet-access RPCs, implement the UI and provider boundaries with an explicit unsupported save path instead of faking persistence.

+# Client Wallet Access Design
+
+Date: 2026-03-25
+Status: Proposed
+
+## Goal
+
+Add a client-centric UI that lets an operator choose which EVM wallets are visible to a given SDK client.
+
+The mental model is:
+
+> For this SDK client, choose which wallets it can see.
+
+This UI should live under the existing `Clients` area, not under `Wallets`, because the permission is being edited from the client's perspective.
+
+## Current Context
+
+The current Flutter app has:
+
+- A top-level dashboard with `Wallets`, `Clients`, and `About`
+- A `Clients` screen that currently acts as a registry/list of `SdkClientEntry`
+- A `Wallets` screen that lists managed EVM wallets
+- An EVM grant creation flow that still manually asks for `Client ID`
+
+Relevant observations from the current codebase:
+
+- `SdkClientEntry` is already a richer admin-facing object than `WalletEntry`
+- `WalletEntry` is currently minimal and not suited to owning the relationship UI
+- The `Clients` screen already presents expandable client rows, which makes it the most natural entry point for a details view
+
+## Chosen Approach
+
+Use a dedicated client details screen.
+
+From the `Clients` list, the operator opens one client and lands on a screen dedicated to that client. That screen includes a wallet access section that shows:
+
+- Client identity and metadata
+- Current wallet access selection
+- A searchable/selectable list of available wallets
+- Save feedback and error states
+
+This is preferred over inline editing or a modal because it scales better when more capabilities are added later, such as:
+
+- Search
+- Bulk actions
+- Explanatory copy
+- Access summaries
+- Future permission categories beyond wallet visibility
+
+## User Experience
+
+### Entry
+
+The operator starts on the existing `Clients` screen.
+
+Each client row gains a clear affordance to open details, for example:
+
+- Tapping the row
+- A trailing button such as `Manage access`
+
+The existing list remains the overview surface. Editing does not happen inline.
+
+### Client Details Screen
+
+The screen is focused on a single client and should contain:
+
+1. A lightweight header with back navigation
+2. A client summary section
+3. A wallet access section
+4. Save/status feedback
+
+The wallet access section is the core interaction:
+
+- Show all available EVM wallets
+- Show which wallets are currently accessible to this client
+- Allow toggling access on/off
+- Allow filtering/searching wallets when the list grows
+- Show empty/loading/error states
+
+### Save Model
+
+Use an explicit save action rather than auto-save.
+
+Reasons:
+
+- Permission changes are administrative and should feel deliberate
+- Multiple checkbox changes can be staged together
+- It creates a clear place for pending, success, and failure states
+
+The screen should track:
+
+- Original selection from the server
+- Current local selection in the form
+- Whether there are unsaved changes
+
+## Information Architecture
+
+### Navigation
+
+Add a nested route under the dashboard clients area for client details.
+
+Conceptually:
+
+- `Clients` remains the list screen
+- `Client Details` becomes the edit/manage screen for one client
+
+This keeps the current top-level tabs intact and avoids turning wallet access into a global dashboard concern.
+
+### Screen Ownership
+
+Wallet visibility is owned by the client details screen, not by the wallets screen.
+
+The wallets screen can remain focused on wallet inventory and wallet creation.
+
+## State Management
+
+Use Riverpod.
+
+State should be split by concern instead of managed in one large widget:
+
+- Provider for the client list
+- Provider for the wallet list
+- Provider for the selected client details data
+- Provider or notifier for wallet-access editing state
+- Mutation/provider for saving wallet access changes
+
+Recommended shape:
+
+- One provider fetches the wallet inventory
+- One provider fetches wallet access for a specific client
+- One notifier owns the editable selection set for the client details form
+- One mutation performs save and refreshes dependent providers
+
+The editing provider should expose:
+
+- Current selected wallet identifiers
+- Original selected wallet identifiers
+- `hasChanges`
+- `isSaving`
+- Validation or request error message when relevant
+
+This keeps the UI declarative and prevents the screen widget from holding all state locally.
+
+## Data Model Assumptions
+
+The UI assumes there is or will be a backend/API surface equivalent to:
+
+- List SDK clients
+- List EVM wallets
+- Read wallet access entries for one client
+- Replace or update wallet access entries for one client
+
+The screen should work with wallet identifiers that are stable from the backend perspective. If the backend only exposes positional IDs today, that should be normalized before binding the UI tightly to list index order.
+
+This is important because the current grant creation screen derives `walletId` from list position, which is not a robust long-term UI contract.
+
+## Layout and Styling Constraints
+
+Implementation must follow these constraints:
+
+- Use Riverpod for screen state and mutations
+- Do not hardcode widths and heights
+- Prefer layout driven by padding, constraints, flex, wrapping, and intrinsic content
+- Keep widgets granular; a widget should not exceed roughly 50 lines
+- Do not place all client-details widgets into a single file
+- Create a dedicated widgets folder for the client details screen
+- Reuse existing UI patterns and helper widgets where it is reasonable, but do not force reuse when it harms clarity
+
+Recommended implementation structure:
+
+- `lib/screens/dashboard/clients/details/`
+- `lib/screens/dashboard/clients/details/client_details.dart`
+- `lib/screens/dashboard/clients/details/widgets/...`
+
+## Widget Decomposition
+
+The client details feature should be composed from small widgets with single responsibilities.
+
+Suggested widget split:
+
+- `ClientDetailsScreen`
+- `ClientDetailsScaffold`
+- `ClientDetailsHeader`
+- `ClientSummaryCard`
+- `WalletAccessSection`
+- `WalletAccessSearchField`
+- `WalletAccessList`
+- `WalletAccessListItem`
+- `WalletAccessEmptyState`
+- `WalletAccessErrorState`
+- `WalletAccessSaveBar`
+
+If useful, existing generic state panels or cards from the current screens can be adapted or extracted, but only where that reduces duplication without making the code harder to follow.
+
+## Interaction Details
+
+### Client Summary
+
+Display the client's:
+
+- Name
+- ID
+- Version
+- Description
+- Public key summary
+- Registration date
+
+This gives the operator confidence that they are editing the intended client.
+
+### Wallet Access List
+
+Each wallet item should show enough identity to make selection safe:
+
+- Human-readable label if one exists in the backend later
+- Otherwise the wallet address
+- Optional secondary metadata if available later
+
+Each item should have a clear selected/unselected control, most likely a checkbox.
+
+### Unsaved Changes
+
+When the current selection differs from the original selection:
+
+- Show a save bar or action row
+- Enable `Save`
+- Optionally show `Reset` or `Discard`
+
+When there are no changes:
+
+- Save action is disabled or visually deemphasized
+
+### Loading and Errors
+
+The screen should independently handle:
+
+- Client not found
+- Wallet list unavailable
+- Wallet access unavailable
+- Save failure
+- Empty wallet inventory
+
+These states should be explicit in the UI rather than collapsed into a blank screen.
+
+## Reuse Guidance
+
+Reasonable reuse candidates from the current codebase:
+
+- Existing color/theme primitives
+- Existing state/empty panels if they can be extracted cleanly
+- Existing wallet formatting helpers, if they are generalized
+
+Reuse should not be prioritized over good boundaries. If the existing widget is too coupled to another screen, create a new focused widget instead.
+
+## Testing Strategy
+
+Plan for widget and provider-level coverage.
+
+At minimum, implementation should be testable for:
+
+- Rendering client summary
+- Rendering preselected wallet access
+- Toggling wallet selection
+- Dirty state detection
+- Save success refresh flow
+- Save failure preserving local edits
+- Empty/loading/error states
+
+Given the current test directory is empty, this feature is a good place to establish basic screen/provider tests rather than relying only on manual verification.
+
+## Out of Scope
+
+The following are not required for the first version unless backend requirements force them:
+
+- Cross-client bulk editing
+- Wallet-side permission management
+- Audit history UI
+- Role templates
+- Non-EVM asset permissions
+
+## Recommendation Summary
+
+Implement wallet access management as a dedicated client details screen under `Clients`.
+
+This gives the cleanest product model:
+
+- `Clients` answers "who is this app/client?"
+- `Wallet access` answers "what wallets can it see?"
+
+It also gives the best technical path for Riverpod-managed state, granular widget decomposition, and future expansion without crowding the existing client list UI.
