Context

With HeroRpcServer and HeroUiServer (from #27) standardizing how all Hero services start, bind sockets, and expose endpoints, we can now build standard tooling on top.

1. Standard Test Helpers

Ship reusable test functions in hero_service::test that any service can import in its integration tests:

use hero_service::test;

#[tokio::test]
async fn test_mandatory_endpoints() {
    // Start the service (spawns process, waits for socket)
    let svc = test::start_service("hero_myservice_server").await;

    // These test the mandatory endpoints every HeroRpcServer provides
    test::assert_health(&svc).await;              // GET /health → 200 + status:ok
    test::assert_openrpc_valid(&svc).await;       // GET /openrpc.json → valid spec
    test::assert_discovery(&svc).await;           // GET /.well-known/heroservice.json
    test::assert_rpc_health(&svc).await;          // POST /rpc rpc.health → ok
    test::assert_rpc_discover(&svc).await;        // POST /rpc rpc.discover → spec

    svc.stop().await;
}

These would connect to ~/hero/var/sockets/{service_name}.sock via HTTP and validate responses.

2. E2E Test Harness

A test runner that starts server + ui, runs all standard tests, then service-specific tests:

// In hero_myservice_examples/tests/e2e.rs
use hero_service::test::ServiceHarness;

#[tokio::test]
async fn e2e() {
    let harness = ServiceHarness::new()
        .server("hero_myservice_server")
        .ui("hero_myservice_ui")
        .start()
        .await;

    // Standard tests run automatically
    // Then service-specific:
    let resp = harness.rpc_call("mymethod.get", json!({"sid": "123"})).await;
    assert!(resp.is_ok());

    harness.stop().await;
}

3. `hero_service` CLI Binary

A binary in hero_rpc that provides standardized commands across all services:

# Run both server + ui for a service
hero_service run hero_osis          # starts hero_osis_server + hero_osis_ui via zinit
hero_service stop hero_osis         # stops both
hero_service status                 # shows all running hero services

# Test a running service
hero_service test hero_osis          # runs standard endpoint tests
hero_service test --all              # tests all discovered services

# Discover services
hero_service list                    # lists all sockets in ~/hero/var/sockets/
hero_service health                  # health check all services
hero_service discover hero_osis      # fetch and print openrpc spec

This replaces per-repo Makefile targets with a single tool that knows the conventions.

4. Standardize Makefile Targets

With hero_service CLI, Makefiles become thin wrappers:

run:    hero_service run $(SERVICE_NAME)
stop:   hero_service stop $(SERVICE_NAME)
test:   hero_service test $(SERVICE_NAME)
status: hero_service status $(SERVICE_NAME)

Implementation Priority

Test helpers (hero_service::test) — highest value, enables CI
hero_service CLI binary — developer ergonomics
E2E harness — integration testing framework
Makefile standardization — convenience

Implementation Context

This issue builds on the unified server lifecycle from #27. Here's what exists now and what needs to be built.

Current State (from #27)

hero_service crate (in hero_rpc repo, branch development_home27):

HeroRpcServer — RPC server builder with mandatory endpoints (/health, /openrpc.json, /.well-known/heroservice.json)
HeroUiServer — UI server builder (no mandatory endpoint injection)
HeroServer — base: Unix socket binding, graceful shutdown, lifecycle CLI
HeroLifecycle — hero_init process management (run/start/stop/status/logs)
LifecycleCommand — clap enum with standard CLI subcommands
serve_unix() — shared UDS accept loop helper
NoServeArgs — empty args for simple services

Socket convention: ~/hero/var/sockets/{service_name}.sock

Mandatory endpoints (HeroRpcServer only):

GET /health → {"status":"ok","service":"...","version":"..."}
GET /openrpc.json → the spec passed at construction
GET /.well-known/heroservice.json → {"protocol":"openrpc","name":"...","version":"...","description":"..."}

Services already migrated:

hero_inspector_server → HeroRpcServer
hero_inspector_ui → HeroUiServer
hero_osis_server → HeroRpcServer (single socket, _context in params)
hero_osis_ui → HeroUiServer

hero_init (forked from zinit, at lhumina_code/hero_init, branch development_home27):

hero_init_sdk — Rust SDK for hero_init process supervisor
Socket: ~/hero/var/sockets/hero_init_server.sock
Env var: HERO_INIT_SOCKET

Key Files

File	Purpose
`hero_rpc/crates/service/src/hero_server.rs`	HeroServer, HeroRpcServer, HeroUiServer, serve_unix()
`hero_rpc/crates/service/src/lifecycle.rs`	HeroLifecycle (hero_init integration)
`hero_rpc/crates/service/src/cli.rs`	LifecycleCommand enum
`hero_rpc/crates/service/src/lib.rs`	Public exports
`hero_rpc/crates/service/Cargo.toml`	Dependencies (hero_init_sdk, axum, hyper, etc.)

What to Build

1. Test helpers (`hero_service::test` module)

Add a new module hero_rpc/crates/service/src/test.rs with:

/// Connect to a service's Unix socket and verify /health returns 200 + status:ok
pub async fn assert_health(service_name: &str) -> Result<()>

/// Connect and verify /openrpc.json returns a valid OpenRPC spec
pub async fn assert_openrpc_valid(service_name: &str) -> Result<()>

/// Connect and verify /.well-known/heroservice.json returns discovery manifest
pub async fn assert_discovery(service_name: &str) -> Result<()>

/// Connect and POST /rpc with rpc.health method
pub async fn assert_rpc_health(service_name: &str) -> Result<()>

/// Connect and POST /rpc with rpc.discover method  
pub async fn assert_rpc_discover(service_name: &str) -> Result<()>

/// Helper to make HTTP requests over Unix socket
pub async fn http_get(service_name: &str, path: &str) -> Result<(StatusCode, String)>
pub async fn http_post(service_name: &str, path: &str, body: &str) -> Result<(StatusCode, String)>

These connect to ~/hero/var/sockets/{service_name}.sock via HTTP over UDS (using hyper + hyperlocal or similar). They're meant for integration tests in service repos.

2. Service harness (`hero_service::test::ServiceHarness`)

pub struct ServiceHarness { /* ... */ }

impl ServiceHarness {
    pub fn new() -> Self;
    pub fn server(self, binary_name: &str) -> Self;
    pub fn ui(self, binary_name: &str) -> Self;
    pub async fn start(self) -> RunningHarness;
}

impl RunningHarness {
    pub async fn rpc_call(&self, method: &str, params: Value) -> Result<Value>;
    pub async fn stop(self);
}

Starts service binaries as child processes, waits for their sockets to appear, runs standard endpoint tests automatically, provides rpc_call for service-specific tests.

3. `hero_service` CLI binary

New binary in hero_rpc/crates/service/ (or a new hero_rpc/crates/hero_service_cli/ crate):

hero_service run <name>       # starts {name}_server + {name}_ui via hero_init
hero_service stop <name>      # stops both
hero_service status [name]    # shows status of one or all hero services
hero_service test <name>      # runs standard endpoint tests against running service
hero_service test --all       # tests all discovered services
hero_service list             # lists all .sock files in ~/hero/var/sockets/
hero_service health [name]    # health check one or all services
hero_service discover <name>  # fetch and print openrpc spec

Uses hero_init_sdk for lifecycle, hero_service::test for testing, and HTTP over UDS for endpoint checks.

Dependencies Available

Already in hero_service Cargo.toml:

axum, hyper, hyper-util, tower — for HTTP over UDS
hero_init_sdk — for lifecycle management
serde_json — for JSON parsing
dirs — for socket path resolution
clap — for CLI

May need to add:

hyperlocal — for HTTP client over Unix sockets (test helpers)
tokio::process — for spawning service binaries (harness)

All smoke tests pass: 55 passed, 0 failed, 2 skipped / 57 total.

The 2 skips are expected grace-period checks:

libraries.list — 1 library found (repos still cloning, threshold is 3)
device.list — 0 devices (device seeding has not run yet)

Both are intentionally coded as skip (not fail) because they depend on async background processes that may not complete within the test window.

The 6 failures from previous sessions (51/57) were resolved by:

#67: hero_aibroker TOML fix (removed invalid serve subcommand)
#68: zinit text cleanup across compute/lib/skills
#65: hero_proc migration (lifecycle SDK for all services)

Full build: 19/19 Rust builds, 42 binaries, 39 WASM islands, hero_zero:0.1.0-dev image verified.

No code changes needed — all services start correctly and respond to health checks.
