# 0128 — agents_and_robots HTTP API + SSE + apikey + TLS

## Contexto

Hoy `agents_and_robots` solo expone control via `agentctl` CLI local (filesystem-based, `shell/process.Manager`). No hay forma remota de gestionar agentes.

Necesitamos backend HTTP seguro para que un frontend local C++ (issue 0129) pueda listar, start/stop/restart agentes, y streamear logs/status en vivo.

## Decision

**Integrar daemon HTTP DENTRO de `cmd/launcher`** como goroutine. Comparte `process.Manager` + acceso a `shell/memory/*.db` + Matrix clients. Un solo proceso, sin drift entre daemon y supervisor.

**Auth:** `Authorization: Bearer <AGENTS_API_KEY>` con `subtle.ConstantTimeCompare`. Clave 32 bytes hex en `.env` (`AGENTS_API_KEY`). 401 sin header o key invalida.

**TLS:** Traefik en VPS organic-machine.com con LE cert auto. Subdominio `agents.organic-machine.com` (DNS A record nuevo → IP del VPS). Ruta Traefik `agents.organic-machine.com → 127.0.0.1:8487`.

**SSE in-memory pubsub.** NATS OFF de momento (1 cliente local, broker = overhead). Documentar TODO en app.md para anadir bus si llega 2do consumidor.

## Scope v0.1 (lean)

| Verbo | Path | Wrap |
|---|---|---|
| GET | `/health` | 200 OK sin auth (liveness) |
| GET | `/agents` | `Scan` + `StatusAll` + `msg_count_24h` (query `shell/memory/*.db`) |
| GET | `/agents/{id}` | detail + config + `LogTail(200)` |
| POST | `/agents/{id}/start` | `Manager.Start` |
| POST | `/agents/{id}/stop` | `Manager.Stop` |
| POST | `/agents/{id}/restart` | Stop+Start con espera health |
| GET | `/agents/{id}/logs?n=200` | `LogTail` snapshot |

**SSE:**
- `GET /sse/status` — broadcast cambios de status (poll cada 2s + diff)
- `GET /sse/agents/{id}/logs` — tail -f del logfile, emite line events

**Fuera de scope v0.1** (queda v0.2):
- POST `/agents/{id}/message` (send Matrix message)
- PUT `/agents/{id}/config` (config edit)
- SSE messages stream

## Tareas

1. **Nuevo paquete `internal/api`** con server HTTP (stdlib `net/http`, sin gin/echo).
   - `api.New(mgr *process.Manager, apiKey string, port int) *Server`
   - `Server.Run(ctx) error` arranca y bloquea hasta ctx done.
   - Middleware: log + auth + recover.
2. **Handlers REST** sobre `process.Manager`. Tests unitarios con mock manager.
3. **SSE pubsub in-memory** (`internal/api/pubsub.go`):
   - `Bus` con `Subscribe(topic) <-chan event` + `Publish(topic, event)`.
   - Poller goroutine que llama `StatusAll` cada 2s y publica diffs.
   - Tail goroutine por logfile (`file_tail_follow` — buscar en registry o crear).
4. **Integrar en launcher** — `cmd/launcher/main.go` arranca `api.Server` en goroutine si `--api-port > 0`.
5. **Crear systemd unit** `/etc/systemd/system/agents_and_robots.service` con `Restart=always`, `EnvironmentFile=.env`, `ExecStart=.../bin/launcher --log-level info --api-port 8487`.
6. **Traefik route + DNS:**
   - Anadir `agents.organic-machine.com` en DNS (A record).
   - Anadir config Traefik (label en docker-compose del stack o file provider) apuntando a `127.0.0.1:8487`.
7. **Fix drift app.md** — `runtime: systemd-system` ahora es verdad. Verificar con `fn doctor services-spec`.
8. **Tests:**
   - Go: pkg `internal/api` con httptest.
   - e2e: `e2e_checks` en `app.md` con curl smoke.
9. **Deploy:**
   - `rsync_deploy_bash_infra` o `deploy_server` target nuevo.
   - Generar `AGENTS_API_KEY` con `openssl rand -hex 32` y escribir `.env` remoto.
   - `systemctl enable --now agents_and_robots.service`.

## Funciones del registry a usar / proponer

Buscar antes de codear:

- `mcp__registry__fn_search query="tail follow file" lang="go"` — ¿existe `file_tail_follow_go_infra`? Si no, delegar a fn-constructor.
- `mcp__registry__fn_search query="http auth bearer" lang="go"` — middleware auth.
- `mcp__registry__fn_search query="sse server" lang="go"` — helper SSE.
- `systemd_generate_unit_go_infra` + `systemd_install_go_infra` — generar/instalar unit.

## Acceptance

- [ ] `curl -fsS -H 'Authorization: Bearer $KEY' https://agents.organic-machine.com/agents` devuelve lista correcta.
- [ ] Sin header → 401. Con key invalida → 401. Key valida → 200.
- [ ] Start/Stop/Restart cambian estado real del proceso (verificable con `ps`).
- [ ] SSE logs entrega lineas en menos de 1s de aparecer en el archivo.
- [ ] SSE status broadcast tras stop/start manual.
- [ ] systemd unit activo y reinicia tras kill -9.
- [ ] `fn doctor services-spec` reporta OK.
- [ ] Tests Go pasan.

## DoD humano

- **Donde:** terminal local → `curl https://agents.organic-machine.com/agents`. SSE verificable con `curl -N`.
- **Latencia:** SSE log lag < 1s. REST list < 200ms.
- **Onboarding:** README de agents_and_robots actualizado con seccion "HTTP API" + ejemplos curl.

## Riesgos

- DNS propagation puede tardar (configurar con TTL bajo).
- Traefik en este VPS: verificar si esta gestionado por Coolify o standalone — anadir ruta donde corresponda.
- `LogTail` actual solo lee snapshot — necesitamos `tail -f` real para SSE. Si no existe en el registry, ronda previa.
