-# LAI Automatisierung
+# LAI Coding Automation
 
-Kontrollierter Coding-Agent fuer Failure Reports aus
+This service turns explicitly queued Gitea issues into reviewed pull requests. It no longer reads the
-[`lai`](https://gitea.tisinfra.de/christian.meyer/lai). Der Orchestrator verwendet
+Laravel production database and does not merge changes automatically.
-[Aider](https://aider.chat/) headless als austauschbaren Coding-Kern. Git-, Gitea-,
-Policy- und Freigabelogik bleiben in diesem Projekt.
 
-## Warum Aider?
+## Workflow
 
-- scriptbarer Einmal-Auftrag mit `--message-file`
+1. LAI creates one Gitea issue for a wrong-answer report and labels it `ai:queued`.
-- gute Git- und Repository-Map-Unterstuetzung
+2. This worker replaces the label with `ai:running`, clones `main`, and creates `ai/issue-N`.
-- Mistral ueber LiteLLM nutzbar
+3. mini-SWE-agent 2.4.6 implements the issue in a credential-free, unprivileged command environment.
-- automatische Commits koennen deaktiviert werden
+4. The worker rejects protected paths, symlinks, empty patches, and oversized diffs.
-- deutlich kleinerer Betriebsumfang als OpenHands
+5. Deterministic setup and test commands run with isolated test database credentials.
+6. A pull request containing `Fixes #N`, the original problem, changed files, and checks is opened.
+7. The issue is labeled `ai:ready` or `ai:failed` and receives a status comment.
 
-OpenHands bleibt eine moegliche spaetere Alternative fuer komplexere, mehrstufige
+Human review and merge are always required.
-Agentenlaeufe. Sein Headless-Modus arbeitet jedoch immer mit `always-approve`; deshalb
-muessen auch dort unsere externen Policy-Gates erhalten bleiben.
 
-## Ablauf
+## Security boundary
 
-```text
+- Gitea and model credentials exist only in the root worker process.
-failure_reports(open)
+- Agent-issued commands receive a strict environment without inherited worker variables.
-	-> transaktionales Claiming (SKIP LOCKED)
+- The agent runs as the unprivileged `coder` user.
-	-> anonymisierter Agentenauftrag
+- Git metadata lives outside the writable worktree, and Git hooks are disabled for commits.
-	-> frischer Clone von lai.git
+- The Docker socket is not mounted. Repository cloning and pushing use HTTPS with a temporary
-	-> Aider-Aenderung ohne Commit
+  `GIT_ASKPASS` credential file that is deleted immediately.
-	-> Pfad-, Groessen- und Sicherheitsgates
+- `.env`, CI, Docker/deployment files, dependencies, generated storage, and symlinks are rejected.
-	-> Tests
-	-> Commit
-	-> PR oder kontrollierter Push auf main
-	-> failure_reports(resolved/agent_failed)
-```
 
-Der Coding-Agent erhaelt keinen Zugang zur ERP- oder Kundendatenbank. Rohdaten und
+The container is the intended execution boundary. Do not run the worker directly on a developer host.
-`.env`-Dateien sind ausgeschlossen. Repository-Pushes verwenden `GIT_ASKPASS`; Tokens
-werden nicht in Remote-URLs oder Prozessargumenten gespeichert. Der Orchestrator laeuft
-als privilegierter Containerprozess, startet Aider aber als separaten Benutzer `coder`.
-Dieser Unterprozess erhaelt nur Modell-Credentials, nicht die Failure-DB- oder
-Gitea-Zugangsdaten.
 
-Die nachgelagerten Testprozesse erhalten separat konfigurierte `TEST_DB_*`-Zugangsdaten.
+## Configuration
-Dieser Benutzer darf ausschliesslich die isolierten Testschemas bearbeiten. Fuer Laravel
-werden daraus `DB_*`, `ERP_DB_*` und `COCKPIT_CONFIG_DATABASE` gesetzt; Aider selbst sieht
-diese Werte nie. Produktive ERP- oder Kundenzugangsdaten duerfen hier nicht verwendet werden.
-Vor jedem Testlauf erstellt `npm run build` die Vite-Assets und initialisiert
-`php artisan migrate:fresh --force` das isolierte Laravel-Schema neu. Deshalb muessen alle
-`TEST_DB_*`-Schemas dediziert und vollstaendig entbehrlich sein.
 
-Laravel-Tests laufen mit PHP und Composer direkt im isolierten Worker. Der Docker-Socket
+Copy `.env.example` to `.env` and set `GITEA_TOKEN` plus `MISTRAL_API_KEY`. Existing test database
-des Hosts wird nicht eingebunden. Abgebrochene Claims werden nach standardmaessig 90
+settings can be retained. Commands are separated with `;;`. Laravel's default connection uses
-Minuten wieder freigegeben; `STALE_CLAIM_MINUTES` passt dieses Intervall an.
+`TEST_DB_NAME`, the ERP connection uses `TEST_CUSTOMER_DB`, and cross-schema cockpit fixtures use
-Schlaegt die isolierte Validierung fehl, erhaelt Aider standardmaessig genau einen
+`TEST_CONFIG_DB`. The worker enables database integration tests and supplies a non-secret
-Korrekturversuch mit redigierter Testausgabe. `MAX_AGENT_ATTEMPTS` ist auf 1 bis 3 begrenzt.
+placeholder AI key so mocked provider-discovery tests execute deterministically. Real Gitea and
+model credentials are never copied into the test or agent command environment.
 
-## Schnellstart
+Start the worker with Docker Compose. Use `lai-agent check` inside the image for configuration
+validation, `lai-agent preflight` for clean-clone setup and tests without a model call, or
+`lai-agent once` for a single polling cycle.
 
-```bash
+## Archived implementation
-cp .env.example .env
-# FAILURE_DB_PASSWORD und bei Bedarf MISTRAL_API_KEY eintragen
-# TEST_DB_PASSWORD fuer den Benutzer der isolierten Testschemas eintragen
-docker compose build
-docker compose run --rm automation check
-docker compose run --rm automation once
-```
-
-Der Default `AUTOMATION_MODE=dry-run` claimt einen offenen Report, erzeugt den
-anonymisierten Auftrag und setzt ihn danach wieder auf `open`. Es wird weder ein Agent
-gestartet noch gepusht.
-
-## Fortschritt beobachten
-
-```bash
-docker compose ps automation
-docker compose exec automation lai-agent check
-docker compose logs -f automation
-```
-
-Der Worker protokolliert nur sichere Metadaten, keine Prompts, SQL-Ergebnisse, Secrets oder
-Modellausgaben. Fuer jeden Report erscheinen Workspace-Vorbereitung, Agentenversuch, Anzahl
-und Pfade geaenderter Dateien, Policy-Pruefung, jeder Validierungsbefehl, Commit, PR-URL und
-Cleanup. Bei laengeren Agenten- oder Testphasen wird alle 30 Sekunden Laufzeitfortschritt
-ausgegeben. `agent_running` ohne Heartbeat oder Unterprozess deutet auf einen unterbrochenen
-Container hin; normale Claims werden nach `STALE_CLAIM_MINUTES` wieder freigegeben.
-
-## PR-Modus
-
-```dotenv
-AUTOMATION_MODE=pr
-GITEA_USERNAME=automation-bot
-GITEA_TOKEN=...
-MISTRAL_API_KEY=...
-```
-
-Der Bot benoetigt Schreibzugriff auf `christian.meyer/lai` und die Berechtigung,
-Branches sowie Pull Requests anzulegen. Jeder Lauf erstellt
-`ai/failure-{report_id}` und einen PR gegen `main`.
-
-## Direkter main-Modus
-
-```dotenv
-AUTOMATION_MODE=direct-main
-ALLOW_DIRECT_MAIN=true
-GITEA_TOKEN=...
-```
-
-Der zweite Schalter ist ein Kill-Switch. In diesem Modus sind Migrationen, Routes,
-Auth, Middleware, PermissionService und SQLValidatorService zusaetzlich blockiert.
-Branch Protection muss den Bot fuer direkte Pushes explizit zulassen. PR-Modus bleibt
-die empfohlene Betriebsart.
-
-## Modelle
-
-Das Modell wird ausschliesslich ueber `AGENT_MODEL` gewaehlt. Devstral ist der
-Default und ein Coding-Agent, nicht das Chat-Modell der Laravel-Anwendung:
-
-```dotenv
-AGENT_MODEL=mistral/devstral-latest
-MISTRAL_API_KEY=...
-```
-
-Codestral verwendet denselben Mistral-Zugang:
-
-```dotenv
-AGENT_MODEL=mistral/codestral-latest
-MISTRAL_API_KEY=...
-```
-
-Qwen 3.5 27B ueber OpenRouter:
-
-```dotenv
-AGENT_MODEL=openrouter/qwen/qwen3.5-27b
-OPENROUTER_API_KEY=...
-```
-
-Oder mit einem lokalen Ollama auf dem Docker-Host:
-
-```dotenv
-AGENT_MODEL=ollama_chat/qwen3.5:27b
-OLLAMA_API_BASE=http://host.docker.internal:11434
-```
-
-Nach einer Aenderung wird der Worker neu erstellt, damit Compose die neue Umgebung
-uebernimmt:
-
-```bash
-docker compose up -d --force-recreate automation
-docker compose exec -T automation lai-agent check
-```
-
-Aider waehlt das passende Edit-Format anhand des Modells. Das Chat-Modell und
-Coding-Modell sind bewusst getrennt. Fuer Coding-Agenten sollte ein
-agentisch/coding-optimiertes Modell verwendet werden. Ein Wechsel zu OpenHands oder
-einem anderen Backend erfordert einen neuen Adapter neben `AiderAgent`.
-
-## Tests
-
-```bash
-python -m venv .venv
-. .venv/bin/activate
-pip install ".[dev]"
-ruff check src tests
-pytest -q
-```

+The previous database-polling Aider implementation is preserved unchanged in `old_2026-08-31/`.

-- config/cockpit_semantics.php owns device and customer-database semantics.
-- app/Services/AIService.php owns provider calls, pseudonymization boundaries, and response parsing.
-- app/Services/TenantDatabaseService.php owns ERP/config/customer source selection and tenant metadata.
-- Cross-database workflows are orchestrated in ChatController/TenantDatabaseService; one SQL query
-    cannot join tables exposed through different Laravel connections unless the tracked architecture
-    explicitly supports qualified access.
-- app/Services/SQLValidatorService.php owns read-only SQL safety; do not weaken it to accept a fix.
-- app/Http/Controllers/ChatController.php orchestrates routing, execution, answers, and diagnostics.
-- app/Services/FailureTrackingService.php and FailureAutomationService.php own failure handoff.
-- tests/Unit is preferred for deterministic service/context rules; tests/Feature is for HTTP,

-Repair workflow:
-1. Inspect the owning implementation, its configuration, and the nearest existing test first.
-2. State one root-cause hypothesis and make the smallest change that can prove it.
-3. Put reusable business knowledge in tracked semantics configuration, not question-specific code.
-4. A prompt/context fix must test the real generated context. A deterministic SQL builder must test
-    its exact SQL and execute it against synthetic fixtures when useful.
-5. Tests must contain assertions that execute; reject empty loops and broad unrelated fallbacks.
-6. Do not expose protected production methods publicly for tests. Use a test-only subclass.
-7. Do not duplicate one rule in service code and semantics config, or add explanatory comments for
-    self-evident test setup.
-8. Inspect the final diff for malformed edits, unrelated files, hardcoded report values, and tests
-    that pass without exercising the changed behavior. Before retrying an edit, reread the current
-    file and never leave conflict markers or partial methods behind.
-9. PHP config files are executable code. Preserve brackets, commas, quotes, and array nesting; run
-    `php -l` on every changed PHP file before broader tests.
