+[`postit-debian`](https://forgejo.pschneider.fr/notazof/postit-debian)

-# Playbook d'usage des agents IA (Yavsc)
-
-Ce playbook normalise l'usage de Copilot, Plan et Explore dans le depot.
-Il privilegie des sorties verifiables: fichiers, commandes tests, risques.
-
-## Quand utiliser quel agent
-
-- Plan: quand la tache est ambigue, transverse ou risquee.
-- Explore: quand il faut cartographier rapidement des zones du code.
-- Copilot: quand les specifications sont claires et localisees.
-
-## Prompt type (base)
-
-Utiliser ce squelette avant toute tache non triviale:
-
-```text
-Contexte: <projet/fichier/fonction>
-Objectif: <resultat observable>
-Contraintes: <style, archi, perimetre>
-Verification: <tests exacts a lancer>
-Sortie attendue: <fichiers modifies + risques>
-```
-
-## 4 scenarios de reference
-
-## 1) Explorer un bounded context
-
-Intention:
-- Comprendre ou implementer un changement dans un BC sans regression laterale.
-
-Prompt minimal:
-```text
-Explore le BC <nom> avec profondeur medium.
-Retour: composants touches, points d'entree, tests existants et risques.
-```
-
-Preuves attendues:
-- Carte des fichiers a modifier.
-- Test(s) smoke/mandatory proposes.
-
-## 2) Ajouter un smoke test
-
-Intention:
-- Couvrir rapidement un endpoint ou une route publique.
-
-Prompt minimal:
-```text
-Propose un smoke test pour <route/endpoint> dans le projet de test approprie.
-Respecte les conventions de doc/testing.md.
-```
-
-Preuves attendues:
-- Fichier test cree/modifie.
-- Commande precise pour executer le test cible.
-
-## 3) Corriger une regression backend API
-
-Intention:
-- Corriger un bug sans casser un flux voisin.
-
-Prompt minimal:
-```text
-Planifie puis implemente un fix de <symptome> dans <projet>.
-Ajoute/ajuste un test NonRegression rouge puis vert.
-```
-
-Preuves attendues:
-- Explication cause racine.
-- Test non-regression associe.
-- Commande d'execution et resultat attendu.
-
-## 4) Tracer un flux PostIt/OIDC
-
-Intention:
-- Localiser une cassure d'authentification entre client et serveur.
-
-Prompt minimal:
-```text
-Cartographie le flux OIDC PostIt: entrypoints, callback, stockage token,
-refresh. Donne points de rupture probables et tests/verification proposes.
-```
-
-Preuves attendues:
-- Liste ordonnee des etapes du flux.
-- Fichiers critiques.
-- Hypotheses testables.
-
-## Anti-patterns a eviter
-
-- Prompt sans objectif verifiable.
-- Demande trop large sans perimetre de fichiers.
-- Validation basee uniquement sur "ca semble correct".
-- Pas de lien entre changement et niveau de test.
-
-## Gate PR minimale (agent-assiste)
-
-Avant validation:
-- Impact architecture explicite.
-- Rationale de choix agent explicite.
-- Test(s) executes et justifies.
-- Risques residuels documentes.

-# Onboarding guide: agents IA + architecture + tests
-
-Ce guide est optimise pour accelerer la prise en main des agents IA
-(Copilot, Plan, Explore) dans Yavsc, avec une verification rapide
-par les tests.
-
-## Resultat attendu
-
-A la fin du parcours, un contributeur doit pouvoir:
-- Identifier les projets impactes par une modification.
-- Choisir l'agent adapte a l'intention de travail.
-- Produire une proposition de changement verifiable par les tests.
-
-## Parcours en 3 modules
-
-## Module A - Comprendre le terrain (30-45 min)
-
-Objectif: acquerir une lecture fiable de l'architecture.
-
-1. Lire [README.md](../README.md) puis [Architecture.md](Architecture.md).
-2. Lire [architecture/decoupage-organisation.md](architecture/decoupage-organisation.md).
-3. Selon le domaine:
-   - Backend/API: [architecture/workflow-multi-parties.md](architecture/workflow-multi-parties.md)
-   - PostIt: [architecture/postit.md](architecture/postit.md) puis [architecture/postit-oidc.md](architecture/postit-oidc.md)
-
-Definition of done:
-- Expliquer en 5 phrases quelles couches sont touchees.
-- Citer le ou les points d'entree applicatifs a verifier.
-
-## Module B - Boucle tests rapide (20-30 min)
-
-Objectif: verifier rapidement sans lancer toute la suite.
-
-1. Lire [testing.md](testing.md).
-2. Lancer les smoke tests d'abord, puis mandatory selon le projet.
-3. N'elargir au test complet que si le scope depasse le BC touche.
-
-Definition of done:
-- Fournir la commande test executee.
-- Expliquer pourquoi ce niveau de test est suffisant.
-
-## Module C - Usage agentique en production (30-40 min)
-
-Objectif: utiliser les agents comme accelerateurs, pas comme boites noires.
-
-1. Plan: decomposer la tache en etapes verifiables.
-2. Explore: collecter le contexte code/doc precise.
-3. Copilot: implementer localement et verifier.
-
-Regles:
-- Toujours donner un contexte explicite (fichier, but, contrainte).
-- Demander des preuves observables (fichiers modifies, tests, risques).
-- Refuser toute sortie non verifiable.
-
-Definition of done:
-- Une tache simple est livree avec:
-  - Plan
-  - Changement local
-  - Preuve par test
-
-## Routine continue (sans echeance fixe)
-
-Rituels recommandes:
-- Hebdo: revue des prompts qui ont bien fonctionne.
-- Mensuel: mise a jour du present guide et du playbook.
-- A chaque incident: ajouter un anti-pattern dans le playbook.
-
-## Check-list de validation
-
-- Le changement indique son impact architecture.
-- Le choix de l'agent est justifie.
-- La preuve test est incluse.
-- Les risques residuels sont explicitement listes.

-# Cibles pour installer PostIt.Android en Debug sur l'AVD qemu.
-#
-# Usage typique :

-#   make android-install # (re)build l'APK et l'installe (AVD doit tourner)
-#   make android-build   # build l'APK seul (sans install)
-#   make qemu-run        # démarre l'AVD en background
-#   make qemu-stop       # arrête l'émulateur
-#   make qemu-wait-boot  # attend que l'AVD ait fini de booter
-#
-# Variables surchargeables (make VAR=valeur) :
-#   AVD_NAME        default: postit_test_avd
-#                    (l'AVD doit être listé par `avdmanager list avd`)
