-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).

-## Project Overview
-
-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 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.
-
-## Toolchain Setup
-
-Tools are managed via [mise](https://mise.jdx.dev/). Install all required tools:
-```sh
-mise install
-```
-
-Key versions: Rust 1.93.0 (with clippy), Flutter 3.38.9-stable, protoc 29.6, diesel_cli 2.3.6 (sqlite).
-
-## Server (Rust workspace at `server/`)
-
-### Crates
-
-| Crate | Purpose |
-|---|---|
-| `arbiter-proto` | Generated gRPC stubs + protobuf types; compiled from `protobufs/*.proto` via `tonic-prost-build` |
-| `arbiter-server` | Main daemon — actors, DB, EVM policy engine, gRPC service implementation |
-| `arbiter-useragent` | Rust client library for the user agent side of the gRPC protocol |
-| `arbiter-client` | Rust client library for SDK clients |
-
-### Common Commands
-
-```sh
-cd server
-
-# Build
-cargo build
-
-# Run the server daemon
-cargo run -p arbiter-server
-
-# Run all tests (preferred over cargo test)
-cargo nextest run
-
-# Run a single test

-# Lint
-cargo clippy
-
-# Security audit
-cargo audit
-
-# Check unused dependencies
-cargo shear
-
-# Run snapshot tests and update snapshots
-cargo insta review
-```
-
-### Architecture
-
-The server is actor-based using the **kameo** crate. All long-lived state lives in `GlobalActors`:
-
-- **`Bootstrapper`** — Manages the one-time bootstrap token written to `~/.arbiter/bootstrap_token` on first run.
-- **`KeyHolder`** — 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 user agents and SDK clients.
-- **`EvmActor`** — Handles EVM transaction policy enforcement and signing.
-
-Per-connection actors live under `actors/user_agent/` and `actors/client/`, each with `auth` (challenge-response authentication) and `session` (post-auth operations) sub-modules.
-
-**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: 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
-- TLS: self-signed certificate (aws-lc-rs backend), fingerprint distributed via `ArbiterUrl`
-
-**Protocol:** gRPC with Protocol Buffers. The `ArbiterUrl` type encodes host, port, CA cert, and bootstrap token into a single shareable string (printed to console on first run).
-
-### Proto Regeneration
-
-When `.proto` files in `protobufs/` change, rebuild to regenerate:
-```sh
-cd server && cargo build -p arbiter-proto
-```
-
-### Database Migrations
-
-```sh
-# Create a new migration
-diesel migration generate <name> --migration-dir crates/arbiter-server/migrations
-
-# Run migrations manually (server also runs them on startup)
-diesel migration run --migration-dir crates/arbiter-server/migrations
-```
-
-## User Agent (Flutter + Rinf at `useragent/`)
-
-The Flutter app uses [Rinf](https://rinf.cunarist.org) to call Rust code. The Rust logic lives in `useragent/native/hub/` as a separate crate that uses `arbiter-useragent` for the gRPC client.
-
-Communication between Dart and Rust uses typed **signals** defined in `useragent/native/hub/src/signals/`. After modifying signal structs, regenerate Dart bindings:
-
-```sh
-cd useragent && rinf gen
-```
-
-### Common Commands
-
-```sh
-cd useragent
-
-# Run the app (macOS or Windows)
-flutter run
-
-# Regenerate Rust↔Dart signal bindings
-rinf gen
-
-# Analyze Dart code
-flutter analyze
-```
-
-The Rinf Rust entry point is `useragent/native/hub/src/lib.rs`. It spawns actors defined in `useragent/native/hub/src/actors/` which handle Dart↔server communication via signals.

-## 3. Multi-Operator Governance
+## 3. Server Identity
-
-When more than one User Agent is registered, the vault is treated as having multiple operators. In that mode, sensitive actions are governed by voting rather than by a single operator decision.
-
-### 3.1 Voting Rules
-
-Voting is based on the total number of registered operators:
-
-- **1 operator:** no vote is needed; the single operator decides directly.
-- **2 operators:** full consensus is required; both operators must approve.
-- **3 or more operators:** quorum is `floor(N / 2) + 1`.
-
-For a decision to count, the operator's approval or rejection must be signed by that operator's associated key. Unsigned votes, or votes that fail signature verification, are ignored.
-
-Examples:
-
-- **3 operators:** 2 approvals required
-- **4 operators:** 3 approvals required
-
-### 3.2 Actions Requiring a Vote
-
-In multi-operator mode, a successful vote is required for:
-
-- approving new SDK clients
-- granting an SDK client visibility to a wallet
-- approving a one-off transaction
-- approving creation of a persistent grant
-- approving operator replacement
-- approving server updates
-- updating Shamir secret-sharing parameters
-
-### 3.3 Special Rule for Key Rotation
-
-Key rotation always requires full quorum, regardless of the normal voting threshold.
-
-This is stricter than ordinary governance actions because rotating the root key requires every operator to participate in coordinated share refresh/update steps. The root key itself is not redistributed directly, but each operator's share material must be changed consistently.
-
-### 3.4 Root Key Custody
-
-When the vault has multiple operators, the vault root key is protected using Shamir secret sharing.
-
-The vault root key is encrypted in a way that requires reconstruction from user-held shares rather than from a single shared password.
-
-For ordinary operators, the Shamir threshold matches the ordinary governance quorum. For example:
-
-- **2 operators:** `2-of-2`
-- **3 operators:** `2-of-3`
-- **4 operators:** `3-of-4`
-
-In practice, the Shamir share set also includes Recovery Operator shares. This means the effective Shamir parameters are computed over the combined share pool while keeping the same threshold. For example:
-
-- **3 ordinary operators + 2 recovery shares:** `2-of-5`
-
-This ensures that the normal custody threshold follows the ordinary operator quorum, while still allowing dormant recovery shares to exist for break-glass recovery flows.
-
-### 3.5 Recovery Operators
-
-Recovery Operators are a separate peer type from ordinary vault operators.
-
-Their role is intentionally narrow. They can only:
-
-- participate in unsealing the vault
-- vote for operator replacement
-
-Recovery Operators do not participate in routine governance such as approving SDK clients, granting wallet visibility, approving transactions, creating grants, approving server updates, or changing Shamir parameters.
-
-### 3.6 Sleeping and Waking Recovery Operators
-
-By default, Recovery Operators are **sleeping** and do not participate in any active flow.
-
-Any ordinary operator may request that Recovery Operators **wake up**.
-
-Any ordinary operator may also cancel a pending wake-up request.
-
-This creates a dispute window before recovery powers become active. The default wake-up delay is **14 days**.
-
-Recovery Operators are therefore part of the break-glass recovery path rather than the normal operating quorum.
-
-The high-level recovery flow is:

-        end
-        Server-->>Op: Recovery mode active
-    end
-```
-
-### 3.7 Committee Formation
-
-There are two ways to form a multi-operator committee:
-
-- convert an existing single-operator vault by adding new operators
-- bootstrap an unbootstrapped vault directly into multi-operator mode
-
-In both cases, committee formation is a coordinated process. Arbiter does not allow multi-operator custody to emerge implicitly from unrelated registrations.
-
-### 3.8 Bootstrapping an Unbootstrapped Vault into Multi-Operator Mode
-
-When an unbootstrapped vault is initialized as a multi-operator vault, the setup proceeds as follows:
-
-1. An operator connects to the unbootstrapped vault using a User Agent and the bootstrap token.
-2. During bootstrap setup, that operator declares:
-   - the total number of ordinary operators
-   - the total number of Recovery Operators
-3. The vault enters **multi-bootstrap mode**.
-4. While in multi-bootstrap mode:
-   - every ordinary operator must connect with a User Agent using the bootstrap token
-   - every Recovery Operator must also connect using the bootstrap token
-   - each participant is registered individually
-   - each participant's share is created and protected with that participant's credentials
-5. The vault is considered fully bootstrapped only after all declared operator and recovery-share registrations have completed successfully.
-
-This means the operator and recovery set is fixed at bootstrap completion time, based on the counts declared when multi-bootstrap mode was entered.
-
-### 3.9 Special Bootstrap Constraint for Two-Operator Vaults
-
-If a vault is declared with exactly **2 ordinary operators**, Arbiter requires at least **1 Recovery Operator** to be configured during bootstrap.
-
-This prevents the worst-case custody failure in which a `2-of-2` operator set becomes permanently unrecoverable after loss of a single operator.

-## Client Connection Flow
-
-### Authentication Result Semantics
-
-Authentication no longer uses an implicit success-only response shape. Both `client` and `user-agent` return explicit auth status enums over the wire.
-
-- **Client:** `AuthResult` may return `SUCCESS`, `INVALID_KEY`, `INVALID_SIGNATURE`, `APPROVAL_DENIED`, `NO_USER_AGENTS_ONLINE`, or `INTERNAL`
-- **User-agent:** `AuthResult` may return `SUCCESS`, `INVALID_KEY`, `INVALID_SIGNATURE`, `BOOTSTRAP_REQUIRED`, `TOKEN_INVALID`, or `INTERNAL`
-
-This makes transport-level failures and actor/domain-level auth failures distinct:
-
-- **Transport/protocol failures** are surfaced as stream/status errors
-- **Authentication failures** are surfaced as successful protocol responses carrying an explicit auth status
-
-Clients are expected to handle these status codes directly and present the concrete failure reason to the user.
-
-### New Client Approval
-
-When a client whose public key is not yet in the database connects, all connected user agents are asked to approve the connection. The first agent to respond determines the outcome; remaining requests are cancelled via a watch channel.
-
-```mermaid

-2. Both request approval from user agents → both receive approval.
-3. Both `INSERT` the client record → the second insert silently overwrites the first, resetting the nonce.
-
-This means the first connection's nonce is invalidated by the second, causing its challenge verification to fail. A fix requires either serialising new-client registration (e.g. an in-memory lock keyed on pubkey) or replacing the separate check + insert with an `INSERT OR IGNORE` / upsert guarded by a unique constraint on `public_key`.
-
-### Nonce Semantics
-
-The `program_client.nonce` column stores the **next usable nonce** — i.e. it is always one ahead of the nonce last issued in a challenge.
-
-- **New client:** inserted with `nonce = 1`; the first challenge is issued with `nonce = 0`.
-- **Existing client:** the current DB value is read and used as the challenge nonce, then immediately incremented within the same exclusive transaction, preventing replay.

 ## Cryptography
 
 ### Authentication
-- **Client protocol:** ed25519
+- **Signature scheme:** ed25519
-
-### User-Agent Authentication
-
-User-agent authentication supports multiple signature schemes because platform-provided "hardware-bound" keys do not expose a uniform algorithm across operating systems and hardware.
-
-- **Supported schemes:** RSA, Ed25519, ECDSA (secp256k1)
-- **Why:** the user agent authenticates with keys backed by platform facilities, and those facilities differ by platform
-- **Apple Silicon Secure Enclave / Secure Element:** ECDSA-only in practice
-- **Windows Hello / TPM 2.0:** currently RSA-backed in our integration
-
-This is why the user-agent auth protocol carries an explicit `KeyType`, while the SDK client protocol remains fixed to ed25519.

 ## Communication
 
 - **Protocol:** gRPC with Protocol Buffers
-- **Request/response matching:** multiplexed over a single bidirectional stream using per-connection request IDs
 - **Server identity distribution:** `ServerInfo` protobuf struct containing the TLS public key fingerprint
 - **Future consideration:** grpc-web lacks bidirectional stream support, so a browser-based wallet may require protojson over WebSocket
 
-### Request Multiplexing
-
-Both `client` and `user-agent` connections support multiple in-flight requests over one gRPC bidi stream.
-
-- Every request carries a monotonically increasing request ID
-- Every normal response echoes the request ID it corresponds to
-- Out-of-band server messages omit the response ID entirely
-- The server rejects already-seen request IDs at the transport adapter boundary before business logic sees the message
-
-This keeps request correlation entirely in transport/client connection code while leaving actor and domain handlers unaware of request IDs.

-## EVM Policy Engine
-
-### Overview
-
-The EVM engine classifies incoming transactions, enforces grant constraints, and records executions. It is the sole path through which a wallet key is used for signing.
-
-The central abstraction is the `Policy` trait. Each implementation handles one semantic transaction category and owns its own database tables for grant storage and transaction logging.
-
-### Transaction Evaluation Flow
-
-`Engine::evaluate_transaction` runs the following steps in order:
-
-1. **Classify** — Each registered policy's `analyze(context)` inspects the transaction fields (`chain`, `to`, `value`, `calldata`). The first one returning `Some(meaning)` wins. If none match, the transaction is rejected as `UnsupportedTransactionType`.
-2. **Find grant** — `Policy::try_find_grant` queries for a non-revoked grant covering this wallet, client, chain, and target address.
-3. **Check shared constraints** — `check_shared_constraints` runs in the engine before any policy-specific logic. It enforces the validity window, gas fee caps, and transaction count rate limit (see below).
-4. **Evaluate** — `Policy::evaluate` checks the decoded meaning against the grant's policy-specific constraints and returns any violations.
-5. **Record** — If `RunKind::Execution` and there are no violations, the engine writes to `evm_transaction_log` and calls `Policy::record_transaction` for any policy-specific logging (e.g., token transfer volume).

-### Policy Trait
-
-| Method | Purpose |
-|---|---|
-| `analyze` | Pure — classifies a transaction into a typed `Meaning`, or `None` if this policy doesn't apply |
-| `evaluate` | Checks the `Meaning` against a `Grant`; returns a list of `EvalViolation`s |
-| `create_grant` | Inserts policy-specific rows; returns the specific grant ID |
-| `try_find_grant` | Finds a matching non-revoked grant for the given `EvalContext` |
-| `find_all_grants` | Returns all non-revoked grants (used for listing) |
-| `record_transaction` | Persists policy-specific data after execution |
-
-`analyze` and `evaluate` are intentionally separate: classification is pure and cheap, while evaluation may involve DB queries (e.g., fetching past transfer volume).
-
-### Registered Policies
-
-**EtherTransfer** — plain ETH transfers (empty calldata)
-
-- Grant requires: allowlist of recipient addresses + one volumetric rate limit (max ETH over a time window)
-- Violations: recipient not in allowlist, cumulative ETH volume exceeded
-
-**TokenTransfer** — ERC-20 `transfer(address,uint256)` calls
-
-- Recognised by ABI-decoding the `transfer(address,uint256)` selector against a static registry of known token contracts (`arbiter_tokens_registry`)
-- Grant requires: token contract address, optional recipient restriction, zero or more volumetric rate limits
-- Violations: recipient mismatch, any volumetric limit exceeded
-
-### Grant Model
-
-Every grant has two layers:
-
-- **Shared (`evm_basic_grant`)** — wallet, chain, validity period, gas fee caps, transaction count rate limit. One row per grant regardless of type.
-- **Specific** — policy-owned tables (`evm_ether_transfer_grant`, `evm_token_transfer_grant`) holding type-specific configuration.
-
-`find_all_grants` uses a `#[diesel::auto_type]` base join between the specific and shared tables, then batch-loads related rows (targets, volume limits) in two additional queries to avoid N+1.
-
-The engine exposes `list_all_grants` which collects across all policy types into `Vec<Grant<SpecificGrant>>` via a blanket `From<Grant<S>> for Grant<SpecificGrant>` conversion.
-
-### Shared Constraints (enforced by the engine)
-
-These are checked centrally in `check_shared_constraints` before policy evaluation:
-
-| Constraint | Fields | Behaviour |
-|---|---|---|
-| Validity window | `valid_from`, `valid_until` | Emits `InvalidTime` if current time is outside the range |
-| Gas fee cap | `max_gas_fee_per_gas`, `max_priority_fee_per_gas` | Emits `GasLimitExceeded` if either cap is breached |
-| Tx count rate limit | `rate_limit` (`count` + `window`) | Counts rows in `evm_transaction_log` within the window; emits `RateLimitExceeded` if at or above the limit |
-
----
-
-### Known Limitations
-
-- **Only EIP-1559 transactions are supported.** Legacy and EIP-2930 types are rejected outright.
-- **No opaque-calldata (unknown contract) grant type.** The architecture describes a category for unrecognised contracts, but no policy implements it yet. Any transaction that is not a plain ETH transfer or a known ERC-20 transfer is unconditionally rejected.
-- **Token registry is static.** Tokens are recognised only if they appear in the hard-coded `arbiter_tokens_registry` crate. There is no mechanism to register additional contracts at runtime.
-
 ---
 
 ## Memory Protection
 
 The unsealed root key must be held in a hardened memory cell resistant to dumps, page swaps, and hibernation.
 
-- **Current:** A dedicated memory-protection abstraction is in place, with `memsafe` used behind that abstraction today
+- **Current:** Using the `memsafe` crate as an interim solution
-- **Planned:** Additional backends can be introduced behind the same abstraction, including a custom implementation based on `mlock` (Unix) and `VirtualProtect` (Windows)
+- **Planned:** Custom implementation based on `mlock` (Unix) and `VirtualProtect` (Windows)

-# 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.
-

-| `useragent/lib/features/connection/evm/wallet_access.dart` | Modify | Add `listAllWalletAccesses()` function |
-| `useragent/lib/providers/sdk_clients/wallet_access_list.dart` | Create | `WalletAccessListProvider` — fetches full wallet access list with IDs |

-| `useragent/lib/screens/dashboard/evm/grants/grants.dart` | Create | `EvmGrantsScreen` — watches `evmGrantsProvider`; handles loading/error/empty/data states; renders `GrantCard` list |
-| `useragent/lib/router.dart` | Modify | Register `EvmGrantsRoute` in dashboard children |

-## 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.

-## 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 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: DashboardRouter.page,
-      path: '/dashboard',
-      children: [
-        AutoRoute(page: EvmRoute.page, path: 'evm'),
-        AutoRoute(page: ClientsRoute.page, path: 'clients'),
-        AutoRoute(page: EvmGrantsRoute.page, path: 'grants'),
-        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',
-  ),
-  NavigationDestination(
-    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**
-
-```sh
-jj describe -m "feat(nav): add Grants dashboard tab"
-jj new
-```

-# 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 |
