We want to create a runner. It's basically, let's see, like a runtime. We want to support the right language and Python language, where we have an opener PC interface following our best practices, and we embed the full Python environment, but also the right environment. And then we have the hooks to add in right features or python features, whatever we prefer. And then over RPC, we can basically start a job, which is starting, yeah, running Python codes in a certain directory. Um, same thing with rye in a certain directory, so it has, it can be script, uh, by this script. It's always a script, which we then execute. We can do it in a directory, we can have environmental variables, time outs, and then the idea is to fork the runtime process. So we load all the functionality in memory, and for each execution, we get a fork. so that we don't expand the memory too much and we don't have to reload the full python or ride kernel, if you want. I want us to write a performance test so we can see how fast it goes. Um, so for Python and for I for both, and um, Yeah. For logging, we want to do the exact same kind of logging, even we can copy paste the interface of how we did it for, um, our hero proc. I will give you the link.

see code from

• /Volumes/T7/code0/hero_proc/crates/hero_proc_lib

• also see the hero_proc_ui make similar one here, repeat how we did logging & jobs

in this case jobs are the scripts running in runtime python or rhai

(we only need the jobs, the idea is that the hero_proc will be able to call hero_runner when its a python or rhai script)

using following skills

• /hero_proc_service_selfstart
• /hero_crates_best_practices_check

test the _ui _server

Implementation Spec for Issue #1: Initial Hero Runner

Objective

Create a Rust workspace called hero_runner_v2 that provides a runner/runtime for executing Rhai and Python (via RustPython) scripts. The project exposes an OpenRPC (JSON-RPC 2.0) interface over a Unix domain socket, following the exact crate architecture established by hero_proc. hero_proc will call hero_runner when a Python or Rhai script needs to run. The runtime forks (or spawns) a pre-warmed child process for each script execution to avoid reloading the full interpreter kernel each time.

Requirements

• Workspace structure mirrors hero_proc: hero_runner_lib, hero_runner_server, hero_runner_sdk, hero_runner_ui, plus integration test crates
• Rust edition 2024, resolver = "3", workspace-level package metadata and lints
• OpenRPC interface with openrpc.json spec defining all RPC methods; SDK generated via openrpc_client! macro
• Rhai engine embedded (rhai crate)
• Python engine embedded via RustPython
• Job model: script execution request with engine type, script path/inline source, working dir, env vars, timeout, status lifecycle
• Process forking: pre-warmed worker pool that forks per execution
• Logging: replicate HeroLogger pattern from hero_proc_sdk
• UI dashboard: replicate hero_proc_ui pattern (Axum + Askama + Bootstrap 5)
• Self-start/stop: --start/--stop CLI flags for hero_proc registration
• Performance tests for both Rhai and Python
• Integration tests for full stack

Crate Structure

Crate	Type	Description
hero_runner_lib	Library	Shared SQLite-backed job & log storage
hero_runner_server	Binary	Server daemon with JSON-RPC over Unix socket, Rhai/Python engines, worker pool
hero_runner_sdk	Library	Generated typed client from OpenRPC spec
hero_runner_ui	Binary	Web admin dashboard (Axum + Askama + Bootstrap 5)
hero_runner_integration_test	Binary	Integration test runner + perf benchmarks

Implementation Plan (6 Steps)

Step 1: Scaffold workspace + hero_runner_lib
Create Cargo workspace, .gitignore, buildenv.sh. Build shared library with SQLite-backed job and log models, CRUD operations.

Step 2: Create hero_runner_server
OpenRPC spec, JSON-RPC dispatch over Unix socket, Rhai + Python engine integration, worker pool with process forking.

Step 3: Create hero_runner_sdk
Generated OpenRPC client, JobBuilder, HeroLogger, socket helpers, lifecycle (self-start/stop).

Step 4: Create hero_runner_ui
Web dashboard with job management, log viewer, engine status. Self-start/stop registration.

Step 5: Create test scripts + integration tests
Rhai/Python test scripts, job lifecycle tests, engine-specific tests, UI tests, performance benchmarks.

Step 6: Add Makefile + CI
Build/test/run targets, Forgejo Actions workflows.

Acceptance Criteria

• cargo build --workspace compiles
• cargo test -p hero_runner_lib passes
• Server responds to system.ping over Unix socket
• Rhai script execution via job.submit works
• Python script execution via RustPython works
• Timeout enforcement works
• Env vars passed to script contexts
• Job status lifecycle: pending → running → succeeded/failed
• UI dashboard serves on Unix socket
• Self-start registers with hero_proc
• Forked execution faster than cold-start
• Integration tests pass
• rpc.discover returns OpenRPC spec

Test Results

All tests passing after fixing 5 test failures.

Summary

• Total tests: 91 (across 10 test targets + 3 doctest targets)
• Passed: 91
• Failed: 0
• Ignored: 3 (doctests)

Fixes Applied

Fixed 5 failing tests caused by two bugs in crates/hero_runner_lib/src/db/jobs/model.rs:

1. JobFilter::default() set limit to 0 instead of 100 — The #[derive(Default)] produced limit: 0, but tests expected the serde default of 100. Fixed by implementing Default manually for JobFilter.

2. Job struct required id field during deserialization — The job.submit RPC handler deserializes params into a Job, but submit requests don't include id. Added #[serde(default)] to id, status, stdout, stderr, and created_at fields.
