hero_proc — Central Process Manager

hero_proc replaces zinit as the unified process manager for all Hero services.

Self-starting services

  • Every service binary supports a --start flag
  • When called with --start, the binary uses the Hero SDK to register itself with hero_proc
  • The SDK can be embedded in any binary that needs to be launched as a service
  • No more custom service management code — one pattern for all services
  • Makefile targets call binaries directly: e.g. make run → hero_embedder --start

Startup sequence

  1. Service configures itself and registers a health check
  2. Verifies it is up and running
  3. If not → return error with a clear, actionable prompt
  4. If healthy → continue

Logging

  • All service logs are sent to hero_proc and stored in SQLite
  • Logs are buffered in the SDK (line by line, flushed every second)
  • Structured log prefixes: e.g. embedder.workspace.id.job.id.source
  • Multiple log levels, centralized for observability
  • External work is always tracked as a job; internal work as a log
  • Tree view of all log prefixes available in hero_proc

Status

Get hero_proc working properly, stress test it, then demo via terminal and UI.

OpenRPC / MCP / Inspector

Every Hero service must expose:

  • OpenRPC spec — the single source of truth for the service API
  • Health endpoint
  • MCP access — always provided through hero_inspector, never manually

hero_inspector is the bridge: it reads OpenRPC specs and automatically generates MCP interfaces. No service implements MCP directly. Inspector merges into the proxy and service layer.

Services Architecture

  • Services are a combination of actions (the "run" concept is removed)
  • Actions can connect to each other; jobs execute within actions
  • If a job runs internally, its log is captured automatically via the SDK
  • More modular, fewer mistakes

Git & Branches

  • development_kristof has been merged into development
  • All work continues on development
  • Some fixes may be needed to stabilize after the merge
  • Goal: everything clean on development, then ship

Testing Workflow

  1. Verify manually that things work
  2. If something is broken, capture a screenshot and file an issue
  3. Ask the AI to write a test that targets the issue — the test must fail, proving it catches the problem
  4. Fix the underlying issue
  5. Run the test again and confirm it passes — the fix is validated, and the test stays as a guard against regression

hero_auth & SSO

  • OAuth-based authentication
  • Hero SDK provides a login module for use in applications
  • hero_collab admin manages groups and user membership

hero_collab

  • Group communication tool (Slack alternative)
  • Built on SQLite, OSIS, and OpenRPC
  • Data export via WebDAV
  • Ship it fast — not waiting anymore

UI Theme

  • Revert to the original theme (current one is too plain)

Other Items

  • Nushell integration on Hero
  • Git worktrees for deployment workflows
  • Hero browser MCP in Rust

Shipping Plan

Bulk of code → integration → fix bugs → ship. Services go live one by one. Compute goes live, people can play.

Phase 1 complete: hero_proc replaces zinit in Docker deployment

Commit: bd14ea1 on hero_services development

Done

  • hero_proc_sdk replaces zinit_sdk in hero_services_server
  • hero_proc_server is the process manager in Docker
  • 21/21 services running, Hero OS login page serving
  • Recovery pass using hero_proc restart for failed services

Next phases

  • #52: Migrate 5 services to HeroRpcServer lifecycle CLI (hero_auth, hero_foundry, hero_osis, hero_proxy_ui, hero_indexer_ui)
  • Phase 2: Self-registering services via --start (each binary registers with hero_proc via SDK)
  • Phase 3: hero_services_server becomes optional orchestrator

Progress update — P1 Phase 3 + P2 complete

P1 Phase 3: Self-registration via HeroLifecycle (DONE)

  • Unified lifecycle: Removed ZinitLifecycle alias everywhere (13 binaries, 8 repos). Single pattern: HeroLifecycle from hero_service crate
  • hero_compute migrated: Replaced local zinit_sdk integration with hero_service::HeroLifecycle (3 crates, PR on development_mik_6_1)
  • HeroLifecycle::start() enhanced: Retry policy (max 20, 5s delay, backoff, 300s max, 60s stability), env vars support via .env() builder
  • Self-registration: profile.rs now calls {binary} start — each service registers itself with hero_proc. Falls back to SDK for non-standard exec (shell wrappers, bun scripts)
  • Build system: Added cargo-server-patches.toml — local path overrides for hero_rpc, hero_lib, hero_proc. Builds work from local repos without pushing first
  • Build verified: SKIP_WASM=1 make dist passed — 37 binaries, validation OK
  • All pushed: hero_rpc, hero_services, hero_redis, hero_books, hero_embedder, hero_voice, hero_indexer, hero_os → development

P2: Inspector/MCP cleanup (DONE)

  • Audit: Only hero_auth had manual /mcp endpoint (9 hardcoded tools in mcp.rs)
  • Fix: Added users.update_scope as proper JSON-RPC method + OpenRPC spec entry (was orphan MCP-only tool)
  • Removed: Deleted mcp.rs (417 lines), removed /mcp route from hero_auth
  • Result: MCP is now exclusively served via hero_inspector. Zero services implement /mcp directly. Inspector reads OpenRPC specs and auto-generates MCP tools for all services

P1 Phase 4 (Logging) — status

  • hero_proc SQLite log storage: already done (full CRUD, filtering, 7-day retention)
  • Passive stdout capture from child processes: working
  • Active structured log shipping from services: not yet (next)

Remaining

  • E: Centralized logging (SDK buffering, structured prefixes, log shipping)
  • C: AI/UX bug fixes (#32, #45, #48, #37, #46)
  • D: hero_collab (new service)
  • F: Ship (docs, integration testing, deploy to herodev)

Verified: P1 Phase 3 + P2 — Docker smoke test passed

Docker test results (hero_zero:dev)

  • 21/21 services running via hero_proc
  • 31 Unix sockets active
  • Proxy health: OK
  • Auth RPC + OpenRPC (9 methods incl. users.update_scope): OK
  • Foundry health: OK
  • Inspector health: OK
  • Books health: OK
  • Self-registration with --service-name overrides: working
  • SDK fallback for non-standard exec: working
  • 10s timeout detects binaries without HeroLifecycle

Key fixes since last update

  • start_service_via_binary() now passes --service-name, --run-args, --env to the binary's start command
  • 10s timeout kills binaries that don't support start (run as foreground servers)
  • Profile-prefixed names (user.hero_*) work correctly via --service-name override
  • hero_compute PR merged and pushed to development

Remaining

  • E: Centralized logging (SDK buffering, structured log shipping)
  • C: AI/UX bugs (#32, #45, #48, #37, #46)
  • D: hero_collab
  • F: Ship

All services now have HeroLifecycle

Migrated the last 3 Rust services that were missing lifecycle support:

  • hero_proxy_server: Added clap CLI + HeroLifecycle (keeps raw JSON-RPC protocol)
  • hero_foundry_admin: Added clap CLI + HeroLifecycle (keeps axum 0.8 socket binding)
  • hero_biz: Added HeroLifecycle alongside existing Serve/HashPassword commands

All 3 now support start, stop, status, logs, run subcommands.

Final lifecycle coverage

Pattern Services Count
HeroServer/HeroRpcServer/HeroUiServer auth, foundry, osis, inspector, os 10 binaries
HeroLifecycle direct redis, books, embedder, voice, indexer, aibroker, proxy, foundry_admin, biz 15 binaries
hero_service re-export compute (server, ui, explorer) 3 binaries
No lifecycle (non-Rust) hero_shrimp (Bun/TypeScript) 1 binary

Total: 28/29 Rust binaries have HeroLifecycle. Only hero_shrimp (TypeScript) uses SDK fallback.

Docker test: 20/21 services running, all smoke tests pass.

P1 Phase 4 (Logging) — E1-E4 complete

What was done

  • HeroLogger added to hero_proc_sdk — async buffered log shipper
    • 500-entry buffer, 1s flush interval
    • Ships to hero_proc via logs.insert RPC
    • Methods: info(), error(), warn(), debug(), info_tagged(), flush()
    • Non-blocking — silently skips if hero_proc unavailable
    • Structured src format: service.component.subcomponent (dotted notation)
  • Re-exported via hero_service::HeroLogger and hero_rpc_server::HeroLogger
  • Docker test: 20 services running, proxy OK, no regression

Lifecycle migration also complete

  • hero_proxy_server, hero_foundry_admin, hero_biz migrated to HeroLifecycle
  • 28/29 Rust binaries now have HeroLifecycle (only hero_shrimp = TypeScript excluded)
