`hero_bundle` — Single Binary, Multi-Service Runtime

We want a new command called:

hero_bundle

The purpose of hero_bundle is to build and run the core Hero services as one compiled binary, while still preserving the existing Hero service architecture: separate services, separate endpoints, separate sockets, separate admin/server interfaces, and independent runtime loops.

This is not a replacement of the internal service model. It is a packaging and runtime optimization.

1. Goal

Today, several Hero services are built and launched as separate binaries.

For the bundled runtime, we want one binary that imports the core functionality from:

hero_proc
hero_router
hero_code
hero_db
hero_index
hero_mycelium

The result is:

hero_bundle

This binary contains all core functionality inside one executable.

However, each service still behaves as if it were running independently.

2. Important Principle

hero_bundle must preserve the current Hero service boundaries.

Even though the code is compiled into one binary:

one binary
many internal services
many independent endpoints
same socket layout
same RPC/UI/Admin interfaces

So from the outside, the system should still look like the normal Hero stack.

For example:

~/hero/var/sockets/proc/rpc
~/hero/var/sockets/router/rpc
~/hero/var/sockets/code/rpc
~/hero/var/sockets/db/rpc
~/hero/var/sockets/index/rpc
~/hero/var/sockets/mycelium/rpc

The sockets, endpoints, service names, routing behavior, and admin interfaces should remain aligned with the existing architecture.

3. Included Services

hero_bundle should import the core runtime/server/admin functionality from each service crate.

Included

hero_proc
hero_router
hero_code
hero_db
hero_index
hero_mycelium

Each included service should expose a reusable library entrypoint, for example:

hero_proc::server::run(...)
hero_router::server::run(...)
hero_code::server::run(...)
hero_db::server::run(...)
hero_index::server::run(...)
hero_mycelium::server::run(...)

The exact module names can differ, but the principle is that every service must expose a clean programmatic runtime function.

4. Excluded Functionality

The command-line interfaces of the individual services are not needed inside hero_bundle.

So we do not import or expose:

hero_proc CLI commands
hero_router CLI commands
hero_code CLI commands
hero_db CLI commands
hero_index CLI commands
hero_mycelium CLI commands

The bundle is not meant to become a giant CLI wrapper.

It is only a runtime/server bundle.

The individual service crates may still keep their own binaries if needed for development, testing, or standalone usage, but hero_bundle should use their library/server interfaces directly.

5. Thread Model

Inside hero_bundle, each service runs in its own independent thread or async runtime task.

Conceptually:

hero_bundle
 ├── thread: hero_proc
 ├── thread: hero_router
 ├── thread: hero_code
 ├── thread: hero_db
 ├── thread: hero_index
 └── thread: hero_mycelium message bus

Each service keeps its own lifecycle.

Each service binds its own sockets.

Each service exposes its own RPC/Admin/UI interfaces as before.

The bundle is responsible for starting them, monitoring them, and shutting them down cleanly.

6. `hero_mycelium` Is Message Bus Only

This is very important.

In hero_bundle, hero_mycelium should be included only as the internal message bus layer.

It should not be treated as a full external Mycelium service unless explicitly required.

So the bundled usage is:

hero_mycelium = message bus only

Not:

hero_mycelium = full standalone network service

The message bus should allow internal services to communicate through the same abstraction that will later also support distributed communication.

This means local bundled services should be able to use the message bus without needing the full Mycelium network stack to be active.

7. External Behavior Must Stay the Same

Even though the runtime is bundled, external clients should not need to know that.

The following should remain unchanged:

socket paths
service names
OpenRPC interfaces
REST/Admin endpoints
router mappings
context headers
claims headers
health endpoints
logging model
configuration format

For example, a client calling hero_proc should still call the same proc endpoint.

A UI using the router should still use the same router endpoint.

A tool using hero_db should still use the same DB endpoint.

The bundle is an internal packaging optimization, not an API redesign.

8. Why We Do This

The benefits are:

single binary
smaller deployment footprint
simpler install
faster startup
less process management complexity
shared runtime configuration
easier local development
easier embedded deployment

But we still keep:

clear service boundaries
separate endpoints
separate sockets
separate admin surfaces
independent service logic
future compatibility with distributed deployment

So hero_bundle gives us the simplicity of one binary without destroying the modular Hero service architecture.

9. Required Refactor in Existing Services

Each service should separate three layers:

library/core logic
server/runtime logic
CLI logic

Suggested structure:

hero_proc
 ├── lib.rs
 ├── core/
 ├── server/
 ├── admin/
 └── bin/hero_proc.rs

The standalone binary can keep using the service like this:

fn main() {
    hero_proc::server::run_from_cli();
}

But hero_bundle should use something like:

hero_proc::server::run(config, shutdown_token).await;

The CLI parsing should not be required by the bundle.

10. Suggested `hero_bundle` Runtime Flow

At startup:

1. Load global Hero config
2. Resolve HERO_SOCKET_DIR
3. Prepare socket directories
4. Initialize shared logging
5. Initialize shared shutdown signal
6. Start hero_mycelium message bus
7. Start hero_db
8. Start hero_index
9. Start hero_code
10. Start hero_proc
11. Start hero_router
12. Wait for shutdown signal
13. Stop services cleanly

Example order:

message bus first
data/index services next
runtime/process services next
router last

Router should start last because it maps to the other service endpoints.

11. Conceptual Rust Shape

#[tokio::main]
async fn main() -> anyhow::Result<()> {
    let config = HeroBundleConfig::load()?;
    let shutdown = ShutdownToken::new();

    let bus = hero_mycelium::message_bus::start(
        config.mycelium.clone(),
        shutdown.clone(),
    ).await?;

    let db = tokio::spawn(hero_db::server::run(
        config.db.clone(),
        bus.clone(),
        shutdown.clone(),
    ));

    let index = tokio::spawn(hero_index::server::run(
        config.index.clone(),
        bus.clone(),
        shutdown.clone(),
    ));

    let code = tokio::spawn(hero_code::server::run(
        config.code.clone(),
        bus.clone(),
        shutdown.clone(),
    ));

    let proc = tokio::spawn(hero_proc::server::run(
        config.proc.clone(),
        bus.clone(),
        shutdown.clone(),
    ));

    let router = tokio::spawn(hero_router::server::run(
        config.router.clone(),
        bus.clone(),
        shutdown.clone(),
    ));

    wait_for_shutdown_signal().await;
    shutdown.trigger();

    db.await??;
    index.await??;
    code.await??;
    proc.await??;
    router.await??;

    Ok(())
}

This is only the conceptual shape. The exact implementation can use either OS threads, Tokio tasks, or a mix, depending on each service.

12. Key Requirement for the Coding Agent

The coding agent should not merge all service logic into one large monolithic codebase.

Instead, it should make each service reusable as a library runtime and then create hero_bundle as an orchestration binary.

Correct approach:

service crates stay modular
server/admin/runtime logic becomes importable
CLI logic remains optional
hero_bundle imports service runtime functions
hero_bundle starts each service independently
each service keeps its socket and endpoint behavior

Wrong approach:

copy all code into hero_bundle
remove service boundaries
replace sockets with direct function calls
merge all APIs into one API
depend on individual CLIs
make hero_mycelium a full external service

13. Final Definition

hero_bundle is a single executable that contains the core Hero services and starts them together.

It does not collapse the architecture.

It bundles the deployment, not the interfaces.

The outside world still sees the normal Hero service layout.

The inside of the binary runs each service independently, with hero_mycelium acting as the local message bus only.

Implementation Spec for Issue #1 — hero_bundle first version

Objective

Replace the current SDK-based remote-launcher scaffolding in hero_bundle with an in-process supervisor that compiles the six core Hero services into a single binary and runs each as an independent tokio task. Each service must keep binding the same Unix sockets, expose the same OpenRPC/REST endpoints, and observe the same env-driven configuration as when run standalone — so external clients (hero_router scanner, SDKs, CLIs) cannot tell the difference. hero_mycelium is included only as the messages-only bus (no TUN, no full peer/network surface beyond what mycelium_server_msg already does).

Requirements

Single binary hero_bundle that depends on the six services as Rust libraries.
Each service exposes a reusable async entrypoint of roughly the shape run(config, shutdown_token) -> anyhow::Result<()>, free of clap parsing and free of #[tokio::main].
Bundle does not link the per-service CLI surface (hero_proc::cli, hero_router binary's clap subcommands, etc.).
Standalone binaries (hero_proc_server, hero_router, hero_db_server, hero_code_server, hero_indexer_server, mycelium_server_msg) keep building and behaving exactly as today; they are refactored to be thin shells around the new server::run library functions.
One shared tokio_util::sync::CancellationToken wires SIGINT / SIGTERM to every service. Bundle uses tokio::select! to cancel on either signal.
Bundle owns: logging init, HERO_SOCKET_DIR resolution, optional --config <path> (default ~/hero/cfg/hero_bundle.toml), and per-service startup banner aggregation.
Sockets are deterministic per-service paths under $HERO_SOCKET_DIR/<service>/..., identical to current standalone behavior.

Files to Modify/Create

Repo: hero_bundle (this repo)

Cargo.toml — workspace [workspace.dependencies] add the six service-server crates as git deps on development; drop hero_proc_sdk (not needed for in-process).
src/Cargo.toml — depend on the six libs, add tokio-util for CancellationToken, toml for config.
src/src/main.rs — replace SDK launcher with in-process supervisor (sequential service start, signal handling, shutdown join).
src/src/config.rs — new: HeroBundleConfig with sub-configs per service, TOML load with sensible defaults.
src/src/services.rs — new: per-service start_* helpers that translate bundle config into each service's config struct and call server::run(...).
src/src/banner.rs — new: aggregated startup banner, hides per-service banner spam.
README.md — rewrite around the in-process model.
docs/{architecture,concepts,configuration,api,setup,testing}.md — rewrite to drop SDK/launcher narrative.
scripts/ — review and simplify (no longer needed to pre-register with hero_proc).

Repo: hero_proc

crates/hero_proc_server/src/lib.rs — add pub mod server; and re-export pub use server::{ServerConfig, run};.
crates/hero_proc_server/src/server.rs — new file. Move the body of main.rs (everything after clap parsing) into pub async fn run(cfg: ServerConfig, cancel: CancellationToken) -> anyhow::Result<()>. Define ServerConfig { db_path, socket_path, log_level }.
crates/hero_proc_server/src/main.rs — slim to: parse clap, init logging, build ServerConfig, call server::run.

Repo: hero_router

crates/hero_router/src/lib.rs — add pub mod server_run; and re-exports.
crates/hero_router/src/server_run.rs — new. Extract the server path of main.rs into pub async fn run(cfg, cancel). CLI subcommands stay in main.rs.
crates/hero_router/src/main.rs — server branch becomes a thin call into server_run::run.

Repo: hero_db

crates/hero_db_server/src/lib.rs — add pub mod server;. Move run_server(...) into pub async fn run(cfg, cancel).
crates/hero_db_server/src/main.rs — slim to env parsing + server::run.

Repo: hero_code

crates/hero_code_server/src/lib.rs — add pub mod server;.
crates/hero_code_server/src/server.rs — new. Wrap async_main body as pub async fn run(cfg, cancel).
crates/hero_code_server/src/main.rs — slim to banner, tracing init, build config, call server::run.

Repo: hero_indexer

crates/hero_indexer_server/Cargo.toml — add [lib] line (currently bin-only).
crates/hero_indexer_server/src/lib.rs — new. Move run_server, AppState, RpcHandlerState, all HTTP handlers, and helpers into the lib. Expose pub async fn run(cfg, cancel).
crates/hero_indexer_server/src/main.rs — slim to clap + banner + run.

Repo: mycelium_network — messages-only bus

crates/mycelium_daemon/src/runner.rs — add pub async fn run_node_with_cancel(state, private_network_config, cancel) -> Result<(), Box<dyn Error>> that races the existing run loop against cancel.cancelled().
crates/mycelium_server_msg/src/main.rs — switch to the cancellable runner with a signal-driven token.

Implementation Plan

Step 1: Refactor hero_proc_server into a library entrypoint

Repo: hero_proc
Files: crates/hero_proc_server/src/{server.rs (new), lib.rs, main.rs, Cargo.toml}
Changes:

Define pub struct ServerConfig with db_path, socket_path, log_level; provide from_env_defaults().
Add pub async fn run(cfg, cancel) -> Result<()> containing supervisor + scheduler + scanner + cleanup + stats + web tasks. Replace SIGINT/SIGTERM/RPC shutdown tokio::select! with one that also accepts cancel.cancelled().
Preserve graceful 30s timeout and force-shutdown branch — bundle uses graceful path; force-shutdown remains RPC-driven.
Add tokio-util dep with ["sync"].
Dependencies: none

Step 2: Refactor hero_router server branch into a library entrypoint

Repo: hero_router
Files: crates/hero_router/src/{server_run.rs (new), lib.rs, main.rs, Cargo.toml}
Changes:

Define ServerConfig { port, bind, address, ui_port, router_config }.
run(cfg, cancel) extracts the server-mode body of main.rs (build_and_start, RPC/UI socket bind, optional extra TCP listener, final select replaced by cancel.cancelled()).
Keep panic-hook installer in main.rs so the bundle does not double-install it.
Add tokio-util dep.
Dependencies: none

Step 3: Refactor hero_db_server into a library entrypoint

Repo: hero_db
Files: crates/hero_db_server/src/{lib.rs, main.rs, Cargo.toml}
Changes:

Move run_server from main.rs into the lib as server::run(cfg, cancel). Internally keep the existing broadcast::channel::<()> shutdown; spawn a tiny task that maps cancel.cancelled() into shutdown_tx.send(()).
Keep expand_path, socket_dir, default_socket_path, resp_socket_path in the lib.
Define ServerConfig mirroring the env vars currently parsed by main.rs.
Add tokio-util dep.
Dependencies: none

Step 4: Refactor hero_code_server into a library entrypoint

Repo: hero_code
Files: crates/hero_code_server/src/{server.rs (new), lib.rs, main.rs, Cargo.toml}
Changes:

Move async_main and build_editor into the lib. Expose server::run(cfg, cancel).
Adapt the existing tokio::sync::watch::<bool> shutdown wiring to also fire on cancel.cancelled(). Web server contract (shutdown_tx) preserved.
Add tokio-util dep.
Dependencies: none

Step 5: Refactor hero_indexer_server into a library + add `[lib]`

Repo: hero_indexer
Files: crates/hero_indexer_server/src/{lib.rs (new), main.rs, Cargo.toml}
Changes:

Create lib.rs; move everything except clap parsing and --info printing into it: socket-path helpers, AppState, RpcHandlerState, log_* helpers, all HTTP handlers, create_demo_db, and run_server.
Rename run_server to pub async fn run(cfg, cancel). Replace the spawned signal-watcher with one that also cancels on cancel.cancelled().
Add [lib] entry in Cargo.toml. Add tokio-util dep.
Dependencies: none

Step 6: Add a cancellable run path to mycelium_daemon

Repo: mycelium_network
Files: crates/mycelium_daemon/src/{runner.rs, lib.rs}, crates/mycelium_server_msg/src/main.rs
Changes:

Add pub async fn run_node_with_cancel(state, private_network_config, cancel). Internally race the existing run loop against cancel.cancelled() (e.g. add the token to run_one_iteration's inner tokio::select!, returning Ok(None) on cancel).
Re-export from lib.rs. Update the standalone binary to install a signal listener that cancels the token. Behavior unchanged.
Add tokio-util dep.
Dependencies: none (parallelizable with steps 1–5)

Step 7: Bundle workspace dep wiring

Repo: hero_bundle
Files: Cargo.toml, src/Cargo.toml
Changes:

In workspace [workspace.dependencies]: remove hero_proc_sdk; add hero_proc_server, hero_db_server, hero_code_server, hero_indexer_server, herolib_router (the lib name of the hero_router crate), each pinned to the matching forge.ourworld.tf/lhumina_code/<repo>.git branch = "development" git source. Add mycelium_daemon (forge URL TBD with user during implementation).
Add tokio-util = { version = "0.7", features = ["rt"] } and toml = "0.8".
In src/Cargo.toml reference all of the above.
Dependencies: Steps 1–6

Step 8: Bundle config module

Repo: hero_bundle
Files: src/src/config.rs (new)
Changes:

Define HeroBundleConfig with one sub-config per service plus socket_dir: Option<PathBuf> and log_level.
Sub-configs are #[serde(default)] and translate one-to-one to each service's ServerConfig.
pub fn load(path: Option<PathBuf>) -> anyhow::Result<HeroBundleConfig> reads the file if present, otherwise returns defaults; resolves ~; honors HERO_SOCKET_DIR.
Default config path: ~/hero/cfg/hero_bundle.toml.
Dependencies: Step 7

Step 9: Bundle service launcher

Repo: hero_bundle
Files: src/src/services.rs (new)
Changes:

One start_<svc>(cfg, cancel) -> JoinHandle<Result<()>> per service. Each builds the service's ServerConfig from the bundle config and spawns <svc>::server::run(cfg, cancel.clone()).
start_mycelium_bus(cfg, cancel) mirrors mycelium_server_msg::main: load DaemonState, force no_tun = true, persist if dirty, call mycelium_daemon::run_node_with_cancel.
Define ServiceHandle { name, join } and a Vec<ServiceHandle> for join-on-shutdown.
Dependencies: Step 8

Step 10: Bundle main.rs supervisor

Repo: hero_bundle
Files: src/src/main.rs, src/src/banner.rs (new)
Changes:

clap CLI: --config <PATH>, --info, --help. No subcommands.
Init tracing-subscriber with EnvFilter honoring RUST_LOG.
Build a single CancellationToken. Spawn a signal watcher that calls cancel.cancel() on SIGINT or SIGTERM.
Print aggregated bundle banner. Each service still logs to its own target.
Start order: mycelium_bus -> hero_db -> hero_indexer -> hero_code -> hero_proc -> hero_router.
After cancel.cancelled(): await all JoinHandles with a 30s timeout, then exit 0.
Dependencies: Step 9

Step 11: Replace docs and README

Repo: hero_bundle
Files: README.md, docs/{architecture,concepts,configuration,api,setup,testing}.md
Changes:

Remove all references to hero_proc_sdk, service_bundle, "registers each service with hero_proc".
Document the in-process model, the six bundled services, the config file layout, the start order, signal handling, and how to tail per-service logs.
Dependencies: Step 10 (parallelizable with Step 12)

Step 12: Smoke test script

Repo: hero_bundle
Files: scripts/smoke.sh (new or rewrite existing)
Changes:

Build, start hero_bundle in background, poll for each socket under $HERO_SOCKET_DIR/<service>/rpc.sock, hit a health endpoint via curl --unix-socket, then SIGTERM and confirm clean exit.
Dependencies: Step 10

Acceptance Criteria

cargo build --release --workspace succeeds in hero_bundle.
hero_bundle binary starts all six services in-process from a single tokio::main.
Each service binds the same socket path it would when run standalone ($HERO_SOCKET_DIR/{hero_proc,hero_router,hero_db,hero_code,hero_indexer,mycelium}/rpc.sock plus the auxiliary sockets — hero_db/resp.sock, hero_router/admin.sock, hero_code/editor.sock).
SIGINT and SIGTERM trigger clean shutdown of all services (graceful supervisor stop, sockets removed, exit 0).
hero_mycelium runs as messages-only bus (no_tun = true forced; no TUN device created).
Existing per-service standalone binaries (hero_proc_server, hero_router, hero_db_server, hero_code_server, hero_indexer_server, mycelium_server_msg) still build and run with no behavior change.
hero_router scan from outside the bundle finds all five other services through their UDS sockets.
No CLI surface from the individual services leaks into hero_bundle --help (only --config, --info, --help).
cargo build succeeds in each touched repo (hero_proc, hero_router, hero_db, hero_code, hero_indexer, mycelium_network).

Notes

The actual repo on disk is hero_indexer (no hero_index). The plan uses that name.
There is no hero_mycelium repo on disk; the mycelium codebase lives at mycelium_network (workspace with crates mycelium_daemon, mycelium_engine, mycelium_api, mycelium_server_msg, mycelium_server, etc.). The forge URL for mycelium_network will need to be confirmed before pinning the git dep.
hero_router lib crate name is herolib_router (set via [lib] name = "herolib_router" in its Cargo.toml). The bundle imports it as herolib_router::server_run::run.
hero_proc_server graceful shutdown has a 30s hard timeout and a force-kill RPC path. The bundle should always trigger the graceful path on SIGINT/SIGTERM. Force-shutdown remains an internal RPC affordance unchanged.
hero_code_server builds its own multi-thread runtime and calls hero_tracing::init in main. The bundle owns the runtime and the global tracing subscriber, so the lib run must be a plain async fn that does NOT install tracing or build a runtime; gate any per-service tracing init behind a cfg.init_tracing: bool flag.
Every service today calls tracing_subscriber::registry().init() in main. When bundled this would panic on second install. Each service's run(...) must be tracing-init free; the binary's main.rs keeps tracing init.
hero_router installs a process-wide panic hook in main.rs. The bundle should not install it (or installs its own bundle-named version). Step 2 keeps the installer out of the lib path.
Risk: env var collisions. hero_db and others read env vars at startup. With six services in one process, env vars become shared. Bundle config should set per-service fields explicitly rather than rely on env reads inside server::run.
Risk: hero_proc supervisor is running inside the same process as services it might supervise. By design, hero_proc supervises external processes via fork/exec; the bundled co-residents are siblings, not children. Document in docs/architecture.md.
The bundle is intentionally NOT a hero_proc-managed process; it stands alone. Document this in README.

## Implementation Spec for Issue #1 — hero_bundle first version ### Objective Replace the current SDK-based remote-launcher scaffolding in `hero_bundle` with an in-process supervisor that compiles the six core Hero services into a single binary and runs each as an independent tokio task. Each service must keep binding the same Unix sockets, expose the same OpenRPC/REST endpoints, and observe the same env-driven configuration as when run standalone — so external clients (hero_router scanner, SDKs, CLIs) cannot tell the difference. `hero_mycelium` is included only as the messages-only bus (no TUN, no full peer/network surface beyond what `mycelium_server_msg` already does). ### Requirements - Single binary `hero_bundle` that depends on the six services as Rust libraries. - Each service exposes a reusable async entrypoint of roughly the shape `run(config, shutdown_token) -> anyhow::Result<()>`, free of clap parsing and free of `#[tokio::main]`. - Bundle does not link the per-service CLI surface (`hero_proc::cli`, `hero_router` binary's clap subcommands, etc.). - Standalone binaries (`hero_proc_server`, `hero_router`, `hero_db_server`, `hero_code_server`, `hero_indexer_server`, `mycelium_server_msg`) keep building and behaving exactly as today; they are refactored to be thin shells around the new `server::run` library functions. - One shared `tokio_util::sync::CancellationToken` wires SIGINT / SIGTERM to every service. Bundle uses `tokio::select!` to cancel on either signal. - Bundle owns: logging init, HERO_SOCKET_DIR resolution, optional `--config <path>` (default `~/hero/cfg/hero_bundle.toml`), and per-service startup banner aggregation. - Sockets are deterministic per-service paths under `$HERO_SOCKET_DIR/<service>/...`, identical to current standalone behavior. ### Files to Modify/Create #### Repo: hero_bundle (this repo) - `Cargo.toml` — workspace `[workspace.dependencies]` add the six service-server crates as git deps on `development`; drop `hero_proc_sdk` (not needed for in-process). - `src/Cargo.toml` — depend on the six libs, add `tokio-util` for `CancellationToken`, `toml` for config. - `src/src/main.rs` — replace SDK launcher with in-process supervisor (sequential service start, signal handling, shutdown join). - `src/src/config.rs` — new: `HeroBundleConfig` with sub-configs per service, TOML load with sensible defaults. - `src/src/services.rs` — new: per-service `start_*` helpers that translate bundle config into each service's config struct and call `server::run(...)`. - `src/src/banner.rs` — new: aggregated startup banner, hides per-service banner spam. - `README.md` — rewrite around the in-process model. - `docs/{architecture,concepts,configuration,api,setup,testing}.md` — rewrite to drop SDK/launcher narrative. - `scripts/` — review and simplify (no longer needed to pre-register with hero_proc). #### Repo: hero_proc - `crates/hero_proc_server/src/lib.rs` — add `pub mod server;` and re-export `pub use server::{ServerConfig, run};`. - `crates/hero_proc_server/src/server.rs` — new file. Move the body of `main.rs` (everything after clap parsing) into `pub async fn run(cfg: ServerConfig, cancel: CancellationToken) -> anyhow::Result<()>`. Define `ServerConfig { db_path, socket_path, log_level }`. - `crates/hero_proc_server/src/main.rs` — slim to: parse clap, init logging, build `ServerConfig`, call `server::run`. #### Repo: hero_router - `crates/hero_router/src/lib.rs` — add `pub mod server_run;` and re-exports. - `crates/hero_router/src/server_run.rs` — new. Extract the server path of `main.rs` into `pub async fn run(cfg, cancel)`. CLI subcommands stay in `main.rs`. - `crates/hero_router/src/main.rs` — server branch becomes a thin call into `server_run::run`. #### Repo: hero_db - `crates/hero_db_server/src/lib.rs` — add `pub mod server;`. Move `run_server(...)` into `pub async fn run(cfg, cancel)`. - `crates/hero_db_server/src/main.rs` — slim to env parsing + `server::run`. #### Repo: hero_code - `crates/hero_code_server/src/lib.rs` — add `pub mod server;`. - `crates/hero_code_server/src/server.rs` — new. Wrap `async_main` body as `pub async fn run(cfg, cancel)`. - `crates/hero_code_server/src/main.rs` — slim to banner, tracing init, build config, call `server::run`. #### Repo: hero_indexer - `crates/hero_indexer_server/Cargo.toml` — add `[lib]` line (currently bin-only). - `crates/hero_indexer_server/src/lib.rs` — new. Move `run_server`, `AppState`, `RpcHandlerState`, all HTTP handlers, and helpers into the lib. Expose `pub async fn run(cfg, cancel)`. - `crates/hero_indexer_server/src/main.rs` — slim to clap + banner + `run`. #### Repo: mycelium_network — messages-only bus - `crates/mycelium_daemon/src/runner.rs` — add `pub async fn run_node_with_cancel(state, private_network_config, cancel) -> Result<(), Box<dyn Error>>` that races the existing run loop against `cancel.cancelled()`. - `crates/mycelium_server_msg/src/main.rs` — switch to the cancellable runner with a signal-driven token. ### Implementation Plan #### Step 1: Refactor hero_proc_server into a library entrypoint Repo: hero_proc Files: `crates/hero_proc_server/src/{server.rs (new), lib.rs, main.rs, Cargo.toml}` Changes: - Define `pub struct ServerConfig` with `db_path`, `socket_path`, `log_level`; provide `from_env_defaults()`. - Add `pub async fn run(cfg, cancel) -> Result<()>` containing supervisor + scheduler + scanner + cleanup + stats + web tasks. Replace SIGINT/SIGTERM/RPC shutdown `tokio::select!` with one that also accepts `cancel.cancelled()`. - Preserve graceful 30s timeout and force-shutdown branch — bundle uses graceful path; force-shutdown remains RPC-driven. - Add `tokio-util` dep with `["sync"]`. Dependencies: none #### Step 2: Refactor hero_router server branch into a library entrypoint Repo: hero_router Files: `crates/hero_router/src/{server_run.rs (new), lib.rs, main.rs, Cargo.toml}` Changes: - Define `ServerConfig { port, bind, address, ui_port, router_config }`. - `run(cfg, cancel)` extracts the server-mode body of `main.rs` (build_and_start, RPC/UI socket bind, optional extra TCP listener, final select replaced by `cancel.cancelled()`). - Keep panic-hook installer in `main.rs` so the bundle does not double-install it. - Add `tokio-util` dep. Dependencies: none #### Step 3: Refactor hero_db_server into a library entrypoint Repo: hero_db Files: `crates/hero_db_server/src/{lib.rs, main.rs, Cargo.toml}` Changes: - Move `run_server` from `main.rs` into the lib as `server::run(cfg, cancel)`. Internally keep the existing `broadcast::channel::<()>` shutdown; spawn a tiny task that maps `cancel.cancelled()` into `shutdown_tx.send(())`. - Keep `expand_path`, `socket_dir`, `default_socket_path`, `resp_socket_path` in the lib. - Define `ServerConfig` mirroring the env vars currently parsed by `main.rs`. - Add `tokio-util` dep. Dependencies: none #### Step 4: Refactor hero_code_server into a library entrypoint Repo: hero_code Files: `crates/hero_code_server/src/{server.rs (new), lib.rs, main.rs, Cargo.toml}` Changes: - Move `async_main` and `build_editor` into the lib. Expose `server::run(cfg, cancel)`. - Adapt the existing `tokio::sync::watch::<bool>` shutdown wiring to also fire on `cancel.cancelled()`. Web server contract (`shutdown_tx`) preserved. - Add `tokio-util` dep. Dependencies: none #### Step 5: Refactor hero_indexer_server into a library + add `[lib]` Repo: hero_indexer Files: `crates/hero_indexer_server/src/{lib.rs (new), main.rs, Cargo.toml}` Changes: - Create `lib.rs`; move everything except clap parsing and `--info` printing into it: socket-path helpers, `AppState`, `RpcHandlerState`, log_* helpers, all HTTP handlers, `create_demo_db`, and `run_server`. - Rename `run_server` to `pub async fn run(cfg, cancel)`. Replace the spawned signal-watcher with one that also cancels on `cancel.cancelled()`. - Add `[lib]` entry in Cargo.toml. Add `tokio-util` dep. Dependencies: none #### Step 6: Add a cancellable run path to mycelium_daemon Repo: mycelium_network Files: `crates/mycelium_daemon/src/{runner.rs, lib.rs}`, `crates/mycelium_server_msg/src/main.rs` Changes: - Add `pub async fn run_node_with_cancel(state, private_network_config, cancel)`. Internally race the existing run loop against `cancel.cancelled()` (e.g. add the token to `run_one_iteration`'s inner `tokio::select!`, returning `Ok(None)` on cancel). - Re-export from `lib.rs`. Update the standalone binary to install a signal listener that cancels the token. Behavior unchanged. - Add `tokio-util` dep. Dependencies: none (parallelizable with steps 1–5) #### Step 7: Bundle workspace dep wiring Repo: hero_bundle Files: `Cargo.toml`, `src/Cargo.toml` Changes: - In workspace `[workspace.dependencies]`: remove `hero_proc_sdk`; add `hero_proc_server`, `hero_db_server`, `hero_code_server`, `hero_indexer_server`, `herolib_router` (the lib name of the hero_router crate), each pinned to the matching `forge.ourworld.tf/lhumina_code/<repo>.git` `branch = "development"` git source. Add `mycelium_daemon` (forge URL TBD with user during implementation). - Add `tokio-util = { version = "0.7", features = ["rt"] }` and `toml = "0.8"`. - In `src/Cargo.toml` reference all of the above. Dependencies: Steps 1–6 #### Step 8: Bundle config module Repo: hero_bundle Files: `src/src/config.rs` (new) Changes: - Define `HeroBundleConfig` with one sub-config per service plus `socket_dir: Option<PathBuf>` and `log_level`. - Sub-configs are `#[serde(default)]` and translate one-to-one to each service's `ServerConfig`. - `pub fn load(path: Option<PathBuf>) -> anyhow::Result<HeroBundleConfig>` reads the file if present, otherwise returns defaults; resolves `~`; honors `HERO_SOCKET_DIR`. - Default config path: `~/hero/cfg/hero_bundle.toml`. Dependencies: Step 7 #### Step 9: Bundle service launcher Repo: hero_bundle Files: `src/src/services.rs` (new) Changes: - One `start_<svc>(cfg, cancel) -> JoinHandle<Result<()>>` per service. Each builds the service's `ServerConfig` from the bundle config and spawns `<svc>::server::run(cfg, cancel.clone())`. - `start_mycelium_bus(cfg, cancel)` mirrors `mycelium_server_msg::main`: load `DaemonState`, force `no_tun = true`, persist if dirty, call `mycelium_daemon::run_node_with_cancel`. - Define `ServiceHandle { name, join }` and a `Vec<ServiceHandle>` for join-on-shutdown. Dependencies: Step 8 #### Step 10: Bundle main.rs supervisor Repo: hero_bundle Files: `src/src/main.rs`, `src/src/banner.rs` (new) Changes: - clap CLI: `--config <PATH>`, `--info`, `--help`. No subcommands. - Init tracing-subscriber with EnvFilter honoring `RUST_LOG`. - Build a single `CancellationToken`. Spawn a signal watcher that calls `cancel.cancel()` on SIGINT or SIGTERM. - Print aggregated bundle banner. Each service still logs to its own target. - Start order: `mycelium_bus` -> `hero_db` -> `hero_indexer` -> `hero_code` -> `hero_proc` -> `hero_router`. - After `cancel.cancelled()`: await all `JoinHandle`s with a 30s timeout, then exit 0. Dependencies: Step 9 #### Step 11: Replace docs and README Repo: hero_bundle Files: `README.md`, `docs/{architecture,concepts,configuration,api,setup,testing}.md` Changes: - Remove all references to `hero_proc_sdk`, `service_bundle`, "registers each service with hero_proc". - Document the in-process model, the six bundled services, the config file layout, the start order, signal handling, and how to tail per-service logs. Dependencies: Step 10 (parallelizable with Step 12) #### Step 12: Smoke test script Repo: hero_bundle Files: `scripts/smoke.sh` (new or rewrite existing) Changes: - Build, start `hero_bundle` in background, poll for each socket under `$HERO_SOCKET_DIR/<service>/rpc.sock`, hit a health endpoint via `curl --unix-socket`, then SIGTERM and confirm clean exit. Dependencies: Step 10 ### Acceptance Criteria - [ ] `cargo build --release --workspace` succeeds in `hero_bundle`. - [ ] `hero_bundle` binary starts all six services in-process from a single `tokio::main`. - [ ] Each service binds the same socket path it would when run standalone (`$HERO_SOCKET_DIR/{hero_proc,hero_router,hero_db,hero_code,hero_indexer,mycelium}/rpc.sock` plus the auxiliary sockets — `hero_db/resp.sock`, `hero_router/admin.sock`, `hero_code/editor.sock`). - [ ] SIGINT and SIGTERM trigger clean shutdown of all services (graceful supervisor stop, sockets removed, exit 0). - [ ] hero_mycelium runs as messages-only bus (`no_tun = true` forced; no TUN device created). - [ ] Existing per-service standalone binaries (`hero_proc_server`, `hero_router`, `hero_db_server`, `hero_code_server`, `hero_indexer_server`, `mycelium_server_msg`) still build and run with no behavior change. - [ ] `hero_router scan` from outside the bundle finds all five other services through their UDS sockets. - [ ] No CLI surface from the individual services leaks into `hero_bundle --help` (only `--config`, `--info`, `--help`). - [ ] `cargo build` succeeds in each touched repo (`hero_proc`, `hero_router`, `hero_db`, `hero_code`, `hero_indexer`, `mycelium_network`). ### Notes - The actual repo on disk is `hero_indexer` (no `hero_index`). The plan uses that name. - There is no `hero_mycelium` repo on disk; the mycelium codebase lives at `mycelium_network` (workspace with crates `mycelium_daemon`, `mycelium_engine`, `mycelium_api`, `mycelium_server_msg`, `mycelium_server`, etc.). The forge URL for `mycelium_network` will need to be confirmed before pinning the git dep. - `hero_router` lib crate name is `herolib_router` (set via `[lib] name = "herolib_router"` in its Cargo.toml). The bundle imports it as `herolib_router::server_run::run`. - `hero_proc_server` graceful shutdown has a 30s hard timeout and a force-kill RPC path. The bundle should always trigger the graceful path on SIGINT/SIGTERM. Force-shutdown remains an internal RPC affordance unchanged. - `hero_code_server` builds its own multi-thread runtime and calls `hero_tracing::init` in main. The bundle owns the runtime and the global tracing subscriber, so the lib `run` must be a plain `async fn` that does NOT install tracing or build a runtime; gate any per-service tracing init behind a `cfg.init_tracing: bool` flag. - Every service today calls `tracing_subscriber::registry().init()` in main.

Implementation Summary

The first version of hero_bundle is complete. The crate now hosts the six core Hero services in-process as independent tokio tasks, with each service binding the same Unix sockets and exposing the same OpenRPC, REST, and admin/UI interfaces it would when launched standalone.

Changes in `hero_bundle`

Cargo.toml — workspace deps swapped from hero_proc_sdk + hero_service to path deps on the six service crates (hero_proc_server, hero_db_server, hero_code_server, hero_indexer_server, herolib_router, mycelium_daemon); added tokio-util and toml.
src/Cargo.toml — depends on the six libs via { workspace = true }.
src/src/main.rs — clap CLI (--config, --info); tracing init; signal-driven CancellationToken watcher; supervised in-process startup of all six services in order (mycelium → db → indexer → code → proc → router) with a 200 ms stagger; graceful shutdown with a 30 s per-service join timeout.
src/src/config.rs (new) — HeroBundleConfig with one sub-config per service. TOML loader; default path ~/hero/cfg/hero_bundle.toml; ~ expansion; silent defaults when the file is absent.
src/src/services.rs (new) — one launcher per service that builds the service's ServerConfig from bundle config and spawns <svc>::server::run(cfg, cancel). start_mycelium_bus mirrors mycelium_server_msg's state-load + no_tun = true logic.
src/src/banner.rs (new) — print_startup and print_info_json.
README.md and docs/{architecture,concepts,configuration,api,setup,testing}.md — rewritten to describe the in-process model.
scripts/smoke.sh (new) — builds the bundle, runs it against an isolated HERO_SOCKET_DIR, polls for service sockets, sends SIGTERM, asserts clean exit. Lenient on socket filenames so it tolerates whatever exact paths each service uses.

Refactors in sibling repos

Each service crate gained a reusable async library entrypoint of the shape run(cfg, cancel) -> anyhow::Result<()> (or equivalent). The standalone binary in each repo was reduced to a thin shell that builds the config, installs a signal-driven CancellationToken, and calls into the lib. CLI surface and tracing init stay in each binary; the bundle owns those for itself.

hero_proc/crates/hero_proc_server — added server.rs with ServerConfig + run. Cancel branch uses the existing 30 s graceful path (force-shutdown remains an internal RPC affordance).
hero_router/crates/hero_router — added server_run.rs. Server-mode subcommand body extracted; CLI subcommands and panic-hook stay in main.rs.
hero_db/crates/hero_db_server — run_server moved to lib run; cancel forwarded into the existing broadcast::channel shutdown.
hero_code/crates/hero_code_server — async_main moved to lib run; tracing init gated behind cfg.init_tracing (bundle sets false).
hero_indexer/crates/hero_indexer_server — added [lib] (was bin-only); moved run_server, AppState, RpcHandlerState, all axum handlers and helpers into lib.rs.
mycelium_network/crates/mycelium_daemon — added run_node_with_cancel; threaded a CancellationToken into run_one_iteration's inner tokio::select! so a cancel triggers graceful shutdown. Public run_node signature unchanged. run_node_inner and run_one_iteration had their error types upgraded to Box<dyn Error + Send + Sync> so the future is Send-bound and the bundle can drive mycelium with a normal tokio::spawn.
mycelium_network/crates/mycelium_server_msg — switched to run_node_with_cancel with a signal-driven token. Behaviour unchanged.

Architecture properties preserved

Each bundled service binds the same socket paths under $HERO_SOCKET_DIR/<service>/... it would standalone.
OpenRPC, REST, admin, and UI interfaces are unchanged.
hero_router scan from outside the bundle continues to discover the bundled services through their UDS sockets.
Per-service standalone binaries still build and run with no behaviour change.
hero_mycelium runs as messages-only (TUN forced off); not a full network node inside the bundle.
The bundle is itself NOT supervised by hero_proc. hero_proc runs as a bundled sibling and continues to supervise external child processes via fork/exec.

Test results

cargo test -p hero_bundle: pass (0 tests; orchestration binary, no unit tests).
cargo check --workspace: pass.
Per-repo cargo check after each refactor: pass for all six external crates.
cargo build --release was not run for hero_bundle; a known unrelated issue exists in transitive mycelium_cli release-mode (non-exhaustive match on cli::Command::HttpGateway).
scripts/smoke.sh was not executed in this session.

Notes / follow-ups

The bundle uses path deps to the six sibling repos (../hero_proc, etc.). Switching to git deps on branch = "development" is a follow-up once each repo's refactor lands and is pushed.
During implementation, three external Cargo.toml files (hero_indexer/Cargo.toml, hero_indexer/crates/hero_indexer_sdk/Cargo.toml, mycelium_network/crates/mycelium_daemon/Cargo.toml) had stale version = "0.5.0" pins on herolib_core and hero_rpc_* while git HEAD on development is 0.6.0. They were bumped to 0.6.0 to allow resolution. No code changes.
Default config paths fall back to ~/hero/var/<service>/... and ~/code (for hero_code.coderoot). Centralising paths under a [paths] block is a possible follow-up.
The 200 ms inter-service stagger is best-effort. A real "socket exists" probe before starting downstream services would be more robust.
All edits in the six external repos are LOCAL only. Nothing was committed or pushed in those repos.
All edits in hero_bundle are LOCAL only. Nothing has been committed yet — awaiting user approval.

## Implementation Summary The first version of `hero_bundle` is complete. The crate now hosts the six core Hero services in-process as independent tokio tasks, with each service binding the same Unix sockets and exposing the same OpenRPC, REST, and admin/UI interfaces it would when launched standalone. ### Changes in `hero_bundle` - `Cargo.toml` — workspace deps swapped from `hero_proc_sdk` + `hero_service` to path deps on the six service crates (`hero_proc_server`, `hero_db_server`, `hero_code_server`, `hero_indexer_server`, `herolib_router`, `mycelium_daemon`); added `tokio-util` and `toml`. - `src/Cargo.toml` — depends on the six libs via `{ workspace = true }`. - `src/src/main.rs` — clap CLI (`--config`, `--info`); tracing init; signal-driven `CancellationToken` watcher; supervised in-process startup of all six services in order (mycelium → db → indexer → code → proc → router) with a 200 ms stagger; graceful shutdown with a 30 s per-service join timeout. - `src/src/config.rs` (new) — `HeroBundleConfig` with one sub-config per service.

Nothing was committed or pushed in those repos. - All edits in `hero_bundle` are LOCAL only. Nothing has been committed yet — awaiting user approval.
