-### 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

-
-### 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.

-## 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
-flowchart TD
-    A([Client connects]) --> B[Receive AuthChallengeRequest]
-    B --> C{pubkey in DB?}
-
-    C -- yes --> D[Read nonce\nIncrement nonce in DB]
-    D --> G
-
-    C -- no --> E[Ask all UserAgents:\nClientConnectionRequest]
-    E --> F{First response}
-    F -- denied --> Z([Reject connection])
-    F -- approved --> F2[Cancel remaining\nUserAgent requests]
-    F2 --> F3[INSERT client\nnonce = 1]
-    F3 --> G[Send AuthChallenge\nwith nonce]
-
-    G --> H[Receive AuthChallengeSolution]
-    H --> I{Signature valid?}
-    I -- no --> Z
-    I -- yes --> J([Session started])
-```
-
-### Known Issue: Concurrent Registration Race (TOCTOU)
-
-Two connections presenting the same previously-unknown public key can race through the approval flow simultaneously:
-
-1. Both check the DB → neither is registered.
-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.

 ## 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`, etc.) 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.
-- **Nonce management is not implemented.** The architecture lists nonce deduplication as a core responsibility, but no nonce tracking or enforcement exists yet.

-# Arbiter
-> Policy-first multi-client wallet daemon, allowing permissioned transactions across blockchains
-
-## Security warning
-Arbiter can't meaningfully protect against host compromise. Potential attack flow:
-- Attacker steals TLS keys from database
-- Pretends to be server; just accepts user agent challenge solutions
-- Pretend to be in sealed state and performing DH with client
-- Steals user password and derives seal key
-
-While this attack is highly targetive, it's still possible.

-//! Transport-facing abstractions shared by protocol/session code.
+use futures::{Stream, StreamExt};
-//!
+use tokio::sync::mpsc::{self, error::SendError};
-//! This module defines a small set of transport traits that actors and other
+use tonic::{Status, Streaming};
-//! protocol code can depend on without knowing anything about the concrete
-//! transport underneath.
-//!
-//! The abstraction is split into:
-//! - [`Sender`] for outbound delivery
-//! - [`Receiver`] for inbound delivery
-//! - [`Bi`] as the combined duplex form (`Sender + Receiver`)
-//!
-//! This split lets code depend only on the half it actually needs. For
-//! example, some actor/session code only sends out-of-band messages, while
-//! auth/state-machine code may need full duplex access.
-//!
-//! [`Bi`] remains intentionally minimal and transport-agnostic:
-//! - [`Receiver::recv`] yields inbound messages
-//! - [`Sender::send`] accepts outbound messages
-//!
-//! Transport-specific adapters, including protobuf or gRPC bridges, live in the
-//! crates that own those boundaries rather than in `arbiter-proto`.
-//!
-//! [`Bi`] deliberately does not model request/response correlation. Some
-//! transports may carry multiplexed request/response traffic, some may emit
-//! out-of-band messages, and some may be one-message-at-a-time state machines.
-//! Correlation concerns such as request IDs, pending response maps, and
-//! out-of-band routing belong in the adapter or connection layer built on top
-//! of [`Bi`], not in this abstraction itself.
-//!
-//! # Generic Ordering Rule
-//!
-//! This module consistently uses `Inbound` first and `Outbound` second in
-//! generic parameter lists.
-//!
-//! For [`Receiver`], [`Sender`], and [`Bi`], this means:
-//! - `Receiver<Inbound>`
-//! - `Sender<Outbound>`
-//! - `Bi<Inbound, Outbound>`
-//!
-//! Concretely, for [`Bi`]:
-//! - `recv() -> Option<Inbound>`
-//! - `send(Outbound)`
-//!
-//! [`expect_message`] is a small helper for linear protocol steps: it reads one
-//! inbound message from a transport and extracts a typed value from it, failing
-//! if the channel closes or the message shape is not what the caller expected.
-//!
-//! [`DummyTransport`] is a no-op implementation useful for tests and local
-//! actor execution where no real stream exists.
-//!
-//! # Design Notes
-//!
-//! - [`Bi::send`] returns [`Error`] only for transport delivery failures, such
-//!   as a closed outbound channel.
-//! - [`Bi::recv`] returns `None` when the underlying transport closes.
-//! - Message translation is intentionally out of scope for this module.
