+## Analyse détaillée
+
+### Périmètre
+
+Analyse du nœud d’orchestration `lecoffre_node` et de son `docker-compose.yml` (services, images, ports, volumes, dépendances inter‑services).
+
+### Stack et orchestration
+
+- **Compose**: `version: "3.9"`
+- **Services**: `tor`, `bitcoin`, `blindbit`, `sdk_relay`, `lecoffre-back` (ext), `lecoffre-front` (ext), `ihm_client` (ext), `sdk_signer`, `sdk_storage`, `watchtower`.
+- **Réseau**: bridge `4nk_node_btcnet` (subnet 172.20.0.0/16).
+- **Volumes**:
+  - `4nk_node_bitcoin_data` → `/home/bitcoin/.bitcoin`
+  - `blindbit_data` → `/root/.blindbit-oracle`
+  - `sdk_data` → `/home/bitcoin/.4nk`
+
+### Ordre de démarrage et dépendances
+
+- `tor` → `bitcoin` (healthcheck) → `blindbit` (healthcheck) → `sdk_relay` (healthcheck)
+- Services applicatifs (`lecoffre-back`, `lecoffre-front`, `ihm_client`) démarrent ensuite.
+- `sdk_signer` et `sdk_storage` sont indépendants du pipeline Bitcoin/Blindbit.
+
+### Images et tags
+
+- `tor`: `btcpayserver/tor:0.4.8.10`
+- `bitcoin`: `git.4nkweb.com/4nk/bitcoin:latest`
+- `blindbit`: `git.4nkweb.com/4nk/blindbit-oracle:dev`
+- `sdk_relay`: `git.4nkweb.com/4nk/sdk_relay:dev`
+- `lecoffre-back`: `git.4nkweb.com/4nk/lecoffre-back-mini:ext`
+- `lecoffre-front`: `git.4nkweb.com/4nk/lecoffre-front:ext`
+- `ihm_client`: `git.4nkweb.com/4nk/ihm_client:ext`
+- `sdk_signer`: `git.4nkweb.com/4nk/sdk_signer:latest`
+- `sdk_storage`: `git.4nkweb.com/4nk/sdk_storage:latest`
+- `watchtower`: `containrrr/watchtower`
+
+### Ports exposés (localhost)
+
+- `blindbit`: 8000
+- `sdk_relay`: 8090
+- `lecoffre-back`: 8080
+- `lecoffre-front`: 3004→3000 (127.0.0.2)
+- `ihm_client`: 3003
+- `sdk_signer`: 3001
+- `sdk_storage`: 8081
+
+### Configuration et logs
+
+- `bitcoin`: monte `./bitcoin/bitcoin.conf` en lecture seule.
+- `blindbit`: copie `./blindbit/blindbit.toml` vers `$HOME/.blindbit-oracle/blindbit.toml`.
+- `sdk_relay`: `./relay/sdk_relay.conf` monté en lecture seule; sortie multiplexée vers `/home/bitcoin/.4nk/logs/sdk_relay.log`.
+
+### Healthchecks
+
+- `bitcoin`: `bitcoin-cli getblockchaininfo`
+- `blindbit`: sondage HTTP `GET /tweaks/1`
+- `sdk_relay`: `GET /health`
+
+### Risques et incohérences relevés
+
+- Tags d’images hétérogènes (`latest`, `dev`, `ext`). Préférer une convention unique et traçable.
+- Contrainte interne: usage recommandé du tag `docker-support-v2` au lieu de `latest`. Harmonisation à planifier.
+- `sdk_signer` listé alors qu’il n’est pas utilisé sur la machine. Éviter son démarrage par défaut pour réduire l’empreinte.
+- Exposition multi‑IP (`127.0.0.2` pour `lecoffre-front`). Vérifier la résolution locale et la compatibilité outillage.
+
+### Actions proposées
+
+- Normaliser les tags d’images (`dev-test` pour branches de test; `docker-support-v2` pour releases) et documenter la politique.
+- Paramétrer le démarrage conditionnel de `sdk_signer` (profil/override compose).
+- Centraliser les variables d’environnement communes dans `.env` et documenter leurs valeurs attendues.
+- Aligner la rotation des logs et vérifier la capacité des volumes (`sdk_data`, `bitcoin_data`).

+## Résumé des environnements (plateforme)
+
+### Contexte fonctionnel
+
+- **Site principal**: `https://dev4.4nkweb.com/lecoffre`
+- **Intégration Iframe**: hôte `https://dev4.4nkweb.com`
+- **Service Signer**: utilisé depuis `https://dev3.4nkweb.com`
+
+### Cartographie (compose et apps)
+
+- `lecoffre-front` (Next.js): basePath `/lecoffre`; variables `NEXT_PUBLIC_*` orientées vers `dev4.4nkweb.com` et services backend.
+- `lecoffre-back-mini` (Express): exposé en interne sur 8080; consommé par le front via `NEXT_PUBLIC_API_URL`.
+- `sdk_relay`: exposé sur 8090; consommé par les clients qui en ont besoin.
+- `ihm_client`: exposé sur 3003; intégré/embarqué si nécessaire.
+- `sdk_signer`: non utilisé localement sur la machine, signer consommé depuis `dev3.4nkweb.com`.
+
+### Valeurs attendues (synthèse)
+
+- Front (Next.js):
+  - `NEXT_PUBLIC_FRONT_APP_HOST=dev4.4nkweb.com`
+  - `NEXT_PUBLIC_FRONT_APP_PORT` (selon déploiement; non nécessaire en prod si 443)
+  - `NEXT_PUBLIC_4NK_URL=https://dev4.4nkweb.com`
+  - `NEXT_PUBLIC_4NK_IFRAME_URL=https://dev4.4nkweb.com`
+  - `NEXT_PUBLIC_API_URL` pointant vers l’API (`lecoffre-back-mini`) accessible depuis le navigateur
+  - `NEXT_PUBLIC_BACK_API_*` si utilisés pour construire l’URL back (protocol/host/port/root/version)
+  - `NEXT_PUBLIC_IDNOT_*`, `NEXT_PUBLIC_DOCAPOSTE_API_URL` selon intégrations
+  - `NEXT_PUBLIC_DEFAULT_*` (validator, storages) selon besoins
+
+- Back (`lecoffre-back-mini`):
+  - Variables DB, clés Stripe/Mail, endpoints externes (non détaillés ici; `.env` validés)
+
+- Signer (externe):
+  - Ciblage de `dev3.4nkweb.com` côté front/back pour les opérations de signature.
+
+### Remarques
+
+- Les fichiers `.env` existants sont validés OK.
+- S’assurer de la cohérence entre `basePath` `/lecoffre` et les URLs publiques (liens, redirections, assets).
+- Documenter un `.env.example` à jour dans chaque projet pour reproduire la configuration.
