+Arbiter is a **permissioned signing service** for cryptocurrency wallets. It consists of:
 - **`server/`** — Rust gRPC daemon that holds encrypted keys and enforces policies
-- **`useragent/`** — Flutter app (desktop + mobile + web targets) with a Rust core via `flutter_rust_bridge`
-- **`protobufs/`** — Protocol Buffer definitions shared between server and clients
-- **`docs/`** — `ARCHITECTURE.md` (peer types, flows, threat model) and `IMPLEMENTATION.md`; treat them as the design source of truth and update them when behaviour changes
-- **`scripts/`** — helper scripts, e.g. `gen_erc20_registry.py`
+- **`operator/`** — Flutter desktop app (macOS/Windows) with a Rust backend via Rinf
+- **`protobufs/`** — Protocol Buffer definitions shared between server and client
 
 The vault never exposes key material; it only produces signatures when requests satisfy configured policies.

 ### Architecture
 
-The server is actor-based using the **kameo** crate. Long-lived state lives in `GlobalActors` (`src/actors/mod.rs`):
+The server is actor-based using the **kameo** crate. All long-lived state lives in `GlobalActors`:
 
-- **`Bootstrapper`** — one-time bootstrap token, written to `~/.arbiter/bootstrap_token` on first run
-- **`Vault`** — encrypted root key and the Sealed/Unsealed state machine; on unseal decrypts the root key into a `memsafe`-backed `SafeCell`
-- **`FlowCoordinator`** — cross-connection flow between operators and SDK clients
-- **`OperatorRegistry`** — tracks currently connected operators
-- **`EvmActor`** — EVM transaction policy enforcement and signing
-- **`events`** — a `kameo_actors::MessageBus` (`DeliveryStrategy::Guaranteed`) for cross-actor notifications
+- **`Bootstrapper`** — Manages the one-time bootstrap token written to `~/.arbiter/bootstrap_token` on first run.
+- **`Vault`** — Holds the encrypted root key and manages the Sealed/Unsealed vault state machine. On unseal, decrypts the root key into a `memsafe` hardened memory cell.
+- **`FlowCoordinator`** — Coordinates cross-connection flow between operators and SDK clients.
+- **`EvmActor`** — Handles EVM transaction policy enforcement and signing.
 
-Per-connection state lives under **`src/peers/`**, not `actors/`: `peers/client/` and `peers/operator/`, each with `auth` (challenge-response) and `session` (post-auth) sub-modules; the operator side additionally has `vault_gate/` for the unseal handshake.
+Per-connection actors live under `actors/operator/` and `actors/client/`, each with `auth` (challenge-response authentication) and `session` (post-auth operations) sub-modules.
 
-The gRPC surface lives in **`src/grpc/`**, split per peer (`client/`, `operator/`, `common/`) and per direction (`inbound.rs` — requests to the daemon, `outbound.rs` — server-initiated streams), with `request_tracker.rs` correlating the two.
-
-EVM logic is in `src/evm/`: `policies/ether_transfer/`, `policies/token_transfers/`, `abi.rs`, `safe_signer.rs`.
-
-**Database:** SQLite via `diesel-async` + `bb8`. Schema in `src/db/schema.rs`, models in `src/db/models.rs`, embedded migrations in `crates/arbiter-server/migrations/`. DB file lives at `~/.arbiter/arbiter.sqlite`; tests use a temp-file DB via `db::create_test_pool()`.
-
-Entity ids are newtypes generated by the `declare_id!` macro in `db::models` (`OperatorId`, `ChainId`, …), each a `#[repr(transparent)]` wrapper over `i32` with `to_raw`/`from_raw`. Pass these around instead of bare `i32`.
-
-**Row integrity:** sensitive rows are covered by an HMAC-SHA256 envelope (`src/crypto/integrity/`, table `integrity_envelope`), keyed from the vault root key. A struct becomes coverable by deriving `arbiter_macros::Hashable` and implementing `Integrable` (`KIND` + `VERSION`). When adding or changing a covered entity, keep the derive and the payload version in sync — a mismatch surfaces as `PayloadVersionMismatch` or `MacMismatch` at runtime.
+**Database:** SQLite via `diesel-async` + `bb8` connection pool. Schema managed by embedded Diesel migrations in `crates/arbiter-server/migrations/`. DB file lives at `~/.arbiter/arbiter.sqlite`. Tests use a temp-file DB via `db::create_test_pool()`.
 
 **Cryptography:**
-- Authentication: **ML-DSA-87** (post-quantum, `arbiter-crypto::authn::v1`), challenge-response with per-peer nonce tracking
-- Encryption at rest: XChaCha20-Poly1305, versioned modules (`crypto/encryption/v1.rs`) with a `schema_version` column for transparent migration on unseal
+- Authentication: ed25519 (challenge-response, nonce-tracked per peer)
+- Encryption at rest: XChaCha20-Poly1305 (versioned via `scheme` field for transparent migration on unseal)
 - Password KDF: Argon2
-- Unseal transport: X25519 ephemeral key exchange (`peers/operator/vault_gate/`); `x-wing` (hybrid PQ KEM) is available via `arbiter-crypto`
-- TLS: self-signed certificate (rustls + aws-lc-rs, `prefer-post-quantum`), fingerprint distributed via `ArbiterUrl`
+- Unseal transport: X25519 ephemeral key exchange
+- TLS: self-signed certificate (aws-lc-rs backend), fingerprint distributed via `ArbiterUrl`
 
-Crypto modules are versioned by convention: `mod.rs` re-exports the current `vN`. Add a `v(N+1)` rather than editing an existing version in place.
-
-**Protocol:** gRPC with Protocol Buffers. `ArbiterUrl` encodes host, port, CA cert and bootstrap token into a single shareable string (printed to console on first run).

 ### Proto Regeneration
 
-`arbiter-proto/build.rs` compiles `arbiter.proto`, `operator.proto`, `client.proto` and `evm.proto` (with their `shared/`, `operator/`, `client/` includes) on build:
+When `.proto` files in `protobufs/` change, rebuild to regenerate:

-## User Agent (Flutter + flutter_rust_bridge at `useragent/`)
+## Operator (Flutter + Rinf at `operator/`)
 
-The Flutter app calls Rust through [flutter_rust_bridge](https://cjycode.com/flutter_rust_bridge/) 2.12.0. The Rust side is the `rust_lib_arbiter` crate at `useragent/rust/`; everything exposed to Dart is declared in `useragent/rust/src/api/` and lands in `useragent/lib/src/rust/` (see `useragent/flutter_rust_bridge.yaml`). Dart UI code is organised as `lib/features/`, `lib/screens/`, `lib/widgets/`, `lib/providers/`, `lib/theme/`, with routing in `lib/router.dart` (`router.gr.dart` is generated).
+The Flutter app uses [Rinf](https://rinf.cunarist.org) to call Rust code. The Rust logic lives in `operator/native/hub/` as a separate crate that uses `arbiter-operator` for the gRPC client.
+
+Communication between Dart and Rust uses typed **signals** defined in `operator/native/hub/src/signals/`. After modifying signal structs, regenerate Dart bindings:
+
+```sh
+cd operator && rinf gen
+```
 
 ### Common Commands
 
 ```sh
-cd useragent
+cd operator
 
-# Run the app
+# Run the app (macOS or Windows)
 flutter run
 
-# Regenerate Rust↔Dart bindings after editing rust/src/api/
-mise run codegen        # flutter_rust_bridge_codegen generate
+# Regenerate Rust↔Dart signal bindings
+rinf gen
 
-# Analyze Dart code (also run in CI)
+# Analyze Dart code
 flutter analyze
 ```
 
-Note: `app/` contains only stale generated Flutter artifacts and is not the application source.
+The Rinf Rust entry point is `operator/native/hub/src/lib.rs`. It spawns actors defined in `operator/native/hub/src/actors/` which handle Dart↔server communication via signals.

+# 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 |
+|---|---|---|
+| `operator/lib/theme/palette.dart` | Modify | Add `Palette.token` (indigo accent for token-transfer cards) |
+| `operator/lib/features/connection/evm/wallet_access.dart` | Modify | Add `listAllWalletAccesses()` function |
+| `operator/lib/providers/sdk_clients/wallet_access_list.dart` | Create | `WalletAccessListProvider` — fetches full wallet access list with IDs |
+| `operator/lib/screens/dashboard/evm/grants/widgets/grant_card.dart` | Create | `GrantCard` widget — watches enrichment providers + revoke mutation; one card per grant |
+| `operator/lib/screens/dashboard/evm/grants/grants.dart` | Create | `EvmGrantsScreen` — watches `evmGrantsProvider`; handles loading/error/empty/data states; renders `GrantCard` list |
+| `operator/lib/router.dart` | Modify | Register `EvmGrantsRoute` in dashboard children |
+| `operator/lib/screens/dashboard.dart` | Modify | Add Grants entry to `routes` list and `NavigationDestination` list |
+
+---
+
+## Task 1: Add `Palette.token`
+
+**Files:**
+- Modify: `operator/lib/theme/palette.dart`
+
+- [ ] **Step 1: Add the color**
+
+Replace the contents of `operator/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 operator && 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: `operator/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 `operator/lib/features/connection/evm/wallet_access.dart`:
+
+```dart
+Future<List<SdkClientWalletAccess>> listAllWalletAccesses(
+  Connection connection,
+) async {
+  final response = await connection.ask(
+    OperatorRequest(listWalletAccess: Empty()),
+  );
+  if (!response.hasListWalletAccessResponse()) {
+    throw Exception(
+      'Expected list wallet access response, got ${response.whichPayload()}',
+    );
+  }
+  return response.listWalletAccessResponse.accesses.toList(growable: false);
+}
+```
+
+Each returned `SdkClientWalletAccess` has:
+- `.id` — the `evm_wallet_access` row ID (same value as `wallet_access_id` in a `GrantEntry`)
+- `.access.walletId` — the EVM wallet DB ID
+- `.access.sdkClientId` — the SDK client DB ID
+
+- [ ] **Step 2: Verify**
+
+```sh
+cd operator && flutter analyze lib/features/connection/evm/wallet_access.dart
+```
+
+Expected: no issues.
+
+- [ ] **Step 3: Commit**
+
+```sh
+jj describe -m "feat(evm): add listAllWalletAccesses feature function"
+jj new
+```
+
+---
+
+## Task 3: Create `WalletAccessListProvider`
+
+**Files:**
+- Create: `operator/lib/providers/sdk_clients/wallet_access_list.dart`
+- Generated: `operator/lib/providers/sdk_clients/wallet_access_list.g.dart`
+
+Mirrors the structure of `EvmGrants` in `providers/evm/evm_grants.dart` — class-based `@riverpod` with a `refresh()` method.
+
+- [ ] **Step 1: Write the provider**
+
+Create `operator/lib/providers/sdk_clients/wallet_access_list.dart`:
+
+```dart
+import 'package:arbiter/features/connection/evm/wallet_access.dart';
+import 'package:arbiter/proto/operator.pb.dart';
+import 'package:arbiter/providers/connection/connection_manager.dart';
+import 'package:mtcore/markettakers.dart';
+import 'package:riverpod_annotation/riverpod_annotation.dart';
+
+part 'wallet_access_list.g.dart';
+
+@riverpod
+class WalletAccessList extends _$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 operator && dart run build_runner build --delete-conflicting-outputs
+```
+
+Expected: `operator/lib/providers/sdk_clients/wallet_access_list.g.dart` created. No errors.
+
+- [ ] **Step 3: Verify**
+
+```sh
+cd operator && flutter analyze lib/providers/sdk_clients/
+```
+
+Expected: no issues.
+
+- [ ] **Step 4: Commit**
+
+```sh
+jj describe -m "feat(providers): add WalletAccessListProvider"
+jj new
+```
+
+---
+
+## Task 4: Create `GrantCard` widget
+
+**Files:**
+- Create: `operator/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/operator.pb.dart`): `.id`, `.access.walletId`, `.access.sdkClientId`
+- `WalletEntry` (from `proto/evm.pb.dart`): `.id`, `.address` (List<int>)
+- `SdkClientEntry` (from `proto/operator.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>`
+
+- [ ] **Step 1: Write the widget**
+
+Create `operator/lib/screens/dashboard/evm/grants/widgets/grant_card.dart`:
+
+```dart
+import 'package:arbiter/proto/evm.pb.dart';
+import 'package:arbiter/proto/operator.pb.dart';

+}
+
+String _formatError(Object error) {
+  final message = error.toString();
+  if (message.startsWith('Exception: ')) {
+    return message.substring('Exception: '.length);
+  }
+  return message;

+
+**Files:**
+- Modify: `operator/lib/router.dart`
+- Modify: `operator/lib/screens/dashboard.dart`
+- Regenerated: `operator/lib/router.gr.dart`
+
+- [ ] **Step 1: Add route to `router.dart`**
+
+Replace the contents of `operator/lib/router.dart` with:
+
+```dart
+import 'package:auto_route/auto_route.dart';
+
+import 'router.gr.dart';
+
+@AutoRouterConfig(generateForDir: ['lib/screens'])

+
+```dart
+final routes = [
+  const EvmRoute(),
+  const ClientsRoute(),
+  const EvmGrantsRoute(),

+# Grant Grid View — Design Spec
+
+**Date:** 2026-03-28
+
+## Overview
+
+Add a "Grants" dashboard tab to the Flutter operator 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:** `operator/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:** `operator/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.
+
