**ACLs (Access Control Lists):** - Ajout du type AclConfig dans sources/event.v (allowed_ips CIDR + allowed_tokens) - Chaque source webhook (Gitea, Uptime Kuma, Cron, Generic) supporte les ACLs - Validation IP via X-Forwarded-For / X-Real-IP avant HMAC - Validation Bearer token via Authorization header - Tests: 7 tests ACL (IP exact, CIDR, parse IPv4, ACL vide, IP+token combiné) **Plugin system:** - sources/plugin.v: runner exécutable externe, stdout JSON → Event - Exit 0 = publish, exit ≠ 0 = skip. Timeout configurable - Plugin loop dans server.v (goroutine, toutes les 60s) - Example: scripts/example-plugin-disk.sh (vérifie espace disque) **Docs:** - README.md: ajout source Plugin + section Features complète - ARCHITECTURE.md: flux Plugin, flux ACL, endpoints /metrics /api/silence - ROADMAP.md: Phase 5 → 8/8 complet, ajout v0.6.0 - ntfy-bridge.example.yaml: sections ACLs et Plugins commentées - Version bump: 0.5.0 → 0.6.0

| **Cron** | Webhook | Reçoit des notifs depuis des scripts shell |

## Features
|
||||
|
||||
- **ACLs** — Restriction par IP (CIDR) ou Bearer token sur chaque webhook
|
||||
- **Plugins** — Scripts externes exécutés toutes les 60s, contrat JSON stdout
|
||||
- **Dashboard** — Interface web avec stats, statuts, historique temps réel
|
||||
- **Filtres** — Règles conditionnelles drop/set_priority/add_tag par source
|
||||
- **Actions Ntfy** — Boutons click, vues, broadcast intégrés
|
||||
- **Prometheus** — Endpoint `/metrics` pour Grafana
|
||||
- **Outgoing webhooks** — Forward vers Slack, Discord, JSON
|
||||
- **Silence rules** — Mute temporaire des notifs via API
|
||||
- **Grouping** — Regroupement intelligent des notifs identiques
|
||||
- **State persistence** — Sauvegarde de l'état up/down et silence sur disque
