0001 — LLM-Citations server-seitig binden statt prompt-seitig

+ + + + + + + + + + + + + + + + + + + + + +
Statusaccepted
Datum2026-04-10
RefsIssue #60, Commits eb045d0/ed64399/db3ada9/6ced7ae, Sub-D Tests
+

Kontext

+

Der GWÖ-Antragsprüfer lässt ein LLM (Qwen Plus via DashScope) parlamentarische +Anträge bewerten. Pro Antrag werden via Embedding-Retrieval relevante Chunks +aus den Wahl- und Grundsatzprogrammen der involvierten Parteien zugespielt. +Das LLM gibt im JSON-Output wahlprogramm_scores[*].wahlprogramm.zitate[*] +mit jeweils text, quelle (Source-Label, z.B. "GRÜNE NRW Wahlprogramm +2022, S. 58") und url zurück.

+

Beim ersten Live-Lauf des Sub-D Citation-Property-Tests (siehe ADR 0003) +gegen die Prod-DB wurden drei Halluzinations-Cases gefunden: das LLM hatte +Snippets erfunden und unter realen Source-Labels zitiert. Issue #60 wurde +geöffnet.

+

Optionen

+

Drei strukturell unterschiedliche Wege, das LLM zu binden:

+

Option A — Schärferer Prompt

+

Die ZITATEREGEL im User-Prompt wird verschärft. Konkret:

+
    +
  1. Jeder retrievte Chunk wird mit einer ENUM-ID [Q1], [Q2], … getaggt.
    2. +
  2. Das LLM wird angewiesen, jedes Zitat per [Qn]-Tag an einen Chunk zu + binden, den text wörtlich aus diesem Chunk zu kopieren und das + Source-Label exakt zu übernehmen.
    3. +
  3. Top-K wird von 2 → 5 erhöht, damit die "richtige" Seite häufiger im + Retrieval-Window landet.
    4. +
+

Vorteile: prompt-only, kleiner Diff, keine Server-Pipeline-Änderung.

+

Nachteile: ENUM-Anker im Prompt ist ein weicher Hint. Das LLM darf +zwar den Snippet aus Chunk Qn nehmen, aber es gibt nichts, was es daran +hindert, die Seite aus Chunk Qm in quelle zu schreiben. Cross-Mix bleibt +möglich.

+

Option B — Server-seitige Quellen-Rekonstruktion

+

Nach dem LLM-Call werden die emittierten Zitate Server-seitig nachgearbeitet:

+
    +
  1. Für jedes Zitat im Output-JSON wird der text per Substring oder + 5-Wort-Anker gegen alle retrievten Chunks gematcht.
    2. +
  2. Bei Match: quelle und url werden aus dem matchenden Chunk konstruiert + und der LLM-Output für diese Felder verworfen.
    3. +
  3. Bei kein-Match: das ganze Zitat wird verworfen.
    4. +
+

Vorteile: strukturell — der LLM hat keine Möglichkeit mehr, eine falsche +Quelle anzugeben. Die einzigen zwei Outcomes sind "korrekt zitiert" oder +"verworfen".

+

Nachteile: zusätzlicher Server-seitiger Schritt nach json.loads und +vor Pydantic-Validation. Match-Logik muss konsistent mit Sub-D bleiben.

+

Option C — Schema-Änderung mit quote_id-Feld

+

Statt quelle direkt zu emittieren, soll das LLM ein neues Feld quote_id +(z.B. "Q3") liefern, aus dem der Server quelle/url rekonstruiert.

+

Vorteile: explizit schema-modelliert, keine Heuristik.

+

Nachteile: invasiv (Pydantic-Modell, JSON-Schema, Frontend, DB-Migration); +verlässt sich darauf, dass das LLM die ID korrekt setzt — wenn es lügt, +ist die Bindung futsch.

+

Entscheidung

+

A + B kombiniert. Option A liefert die Vorab-Härtung im Prompt — sie +fängt den Großteil der Cases (etwa 80%). Option B ist die strukturelle +Backstop, die die restlichen 20% (echter Snippet aus Qn, falsche Seite +aus Qm) verlässlich abdeckt. Option C wurde verworfen, weil der Schema- +Eingriff den Aufwand nicht rechtfertigt, solange B die LLM-Eingabe ohnehin +ignoriert.

+

Konkret in dieser Reihenfolge implementiert:

+
    +
  1. db3ada9 — Option A: ENUM-Anker [Q1]/[Q2]/… im Prompt + Top-K 2→5. + Live-Verifikation der drei Original-Cases aus #60: 13/13 ok.
    2. +
  2. Sub-D Live-Run gegen Prod-DB: 45/46 grün, ein neuer Case (BB 8/673) + gefunden mit "echter Snippet, falsche Seite". Beweis dass A allein nicht + reicht.
    3. +
  3. 6ced7ae — Option B: embeddings.reconstruct_zitate(data, semantic_quotes) + nach json.loads und vor Pydantic-Validation. Helpers find_chunk_for_text + und _normalize_for_match mit identischer Logik wie Sub-D. Bei Match wird + _chunk_source_label und _chunk_pdf_url angewendet, bei No-Match wird + das Zitat gedroppt.
    4. +
  4. Sub-D Re-Run nach B: 52/52 grün über NRW/LSA/BE/MV/BB/BUND.
    5. +
+

Konsequenzen

+

Positiv

+
    +
  • Strukturelle Garantie: nach reconstruct_zitate kann ein im DB + gespeichertes Zitat nur noch eines von zwei Dingen sein: korrekt zitiert + aus einem real retrievten Chunk, oder gar nicht da.
    • +
  • Sub-D als CI-Gate: das Property-Test-Pattern fängt jede künftige + Regression dieser Bug-Klasse.
    • +
  • Server vertraut LLM nicht mehr für quelle/url. Künftige Modell- + Wechsel oder Prompt-Drift können die Quellen-Korrektheit nicht mehr brechen.
    • +
+

Negativ

+
    +
  • Fehlende Match-Heuristik = stilles Verschwinden: Wenn der LLM einen + echten Chunk leicht paraphrasiert (z.B. Komma anders gesetzt), verwirft + Option B das Zitat. Die 5-Wort-Anker-Fallback fängt das in den meisten + Fällen, aber Edge-Cases bleiben. Mitigation: doctest-style Sub-D-Run pro + Deploy + Monitor der wahlprogramm_scores[*].zitate-Counts pro Assessment.
    • +
  • Code-Pfad-Komplexität: drei Schichten (Prompt-ENUM, Server-Postprocess, + Sub-D-Test) statt einer. Dafür ist jede Schicht isoliert testbar.
    • +
  • embeddings.py hat jetzt mehr Verantwortung als nur Embedding-Retrieval + — auch Match-Helpers und Source-Label-Konstruktion. Akzeptabel solange das + Modul thematisch geschlossen bleibt; bei weiterem Wachstum als + citations.py extrahieren.
    • +
+

Folgen für andere ADRs

+
    +
  • ADR 0003 (Sub-D Citation-Property-Tests) ist die Test-Säule dieser + Entscheidung — wenn 0003 jemals supersedet wird, bricht 0001 ohne den + Test-Backstop möglicherweise still.
    • +
  • Neue Adapter (zukünftige Bundesländer) müssen sich nicht extra um + Citation-Korrektheit kümmern; der Server-Postprocess ist adapter-agnostisch.

0002 — Adapter-Pattern mit ParlamentAdapter-Basisklasse + Registry

+ + + + + + + + + + + + + + + + + + + + + +
Statusaccepted

RefsIssues #2, #3, #4, #19, #21, #23, #24, #26, #56, parlamente.py
+

Kontext

+

Der GWÖ-Antragsprüfer soll Anträge aus 16 Bundesländern + dem Bundestag +analysieren können. Jedes Parlament hat ein eigenes Doku-System mit +unterschiedlichen Endpoints, Schemas, Auth-Anforderungen und Quirks:

+ + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
FamilieMitgliederCharakter
portala/eUILSA, BE, BB, RPJSON-Tree-Search mit parsed-Strings, HTML-Hits in efxRecordRepeater

PARLIS (eUI-Variante)BWpolling, JSON-in-HTML-Comments
EigensystemeBY (TYPO3-Solr), SL (Umbraco/.NET), SN (ASP.NET-Webforms), BUND (DIP-API)jeweils komplett unique
+

Optionen

+

Option A — Eine Mega-Klasse mit Strategy-Pattern

+

Eine ParlamentAdapter-Klasse mit Strategy-Object pro Doku-System, +gewählt über Konfiguration.

+

Vorteile: zentral, ein Eintrittspunkt für gemeinsame Logik wie +Fraktion-Normalisierung.

+

Nachteile: kompliziert sich schnell, wenn jede Strategy ihre eigenen +Quirks hat (z.B. BB hat Datum-vor-Drucksachennummer im h6, BE hat +730d-Window-Hack, HE hat Perl-Hex-Decoder). Die Trennung wäre +"Strategy mit Subclasses" — und damit sind wir bei B.

+

Option B — Abstract Base + Eine konkrete Klasse pro Familie

+

ParlamentAdapter(ABC) mit search/get_document/download_text-Methoden. +Pro Doku-System eine konkrete Klasse: +PortalaAdapter, ParLDokAdapter, StarFinderCGIAdapter, +StarWebHEAdapter, PARiSHBAdapter, PARLISAdapter, BayernAdapter, +SaarlandAdapter, BundestagAdapter, SNEdasXmlAdapter, NRWAdapter.

+

Wo möglich, wird die Klasse via Konstruktor-Parameter parametrisiert +(PortalaAdapter nimmt 6 BLs auf, ParLDokAdapter 3) statt jede +Wiederverwendung als Subklasse.

+

Registriert in einem ADAPTERS: dict[str, ParlamentAdapter] am Datei-Ende, +indexiert per BL-Code ("NRW", "BUND", …).

+

Vorteile: +- Klare Verantwortlichkeit: ein Test-Lauf gegen einen LT trifft genau + eine Klasse. +- Reverse-Engineering-Findings können als Class-Docstring dokumentiert + werden, wo sie hingehören. +- Parametrisierung erlaubt Wiederverwendung ohne Vererbungs-Hierarchie. +- get_adapter(bundesland) ist O(1).

+

Nachteile: +- Cross-Cutting-Concerns (Fraktion-Normalisierung) müssen separat gelöst + werden — siehe ADR-Folge zur parteien-Zentralisierung in #55.

+

Option C — Separates Modul pro Adapter

+

Ein Python-File pro Adapter (z.B. app/adapters/lsa.py).

+

Vorteile: maximale Datei-Granularität.

+

Nachteile: Import-Overhead, der Registry-Eintrag muss in einer dritten +Datei liegen, kein nennenswerter Vorteil gegenüber B solange die +Adapter-Klassen unter ~500 Zeilen bleiben (PortalaAdapter ist mit ~520 +Zeilen der größte).

+

Entscheidung

+

Option B. Eine parlamente.py mit einer Klasse pro Doku-System, +parametrisierbar wo sinnvoll, registriert in ADAPTERS. Cross-Cutting-Logik +wie Fraktion-Normalisierung wandert in separate Module (parteien.py, +bundeslaender.py) und wird per Import oder Funktions-Argument injiziert.

+

Konsequenzen

+

Positiv

+
    +
  • 17 Adapter sauber separierbar in ~3000 Zeilen parlamente.py. Jeder + Adapter kommt mit seinem Reverse-Engineering-Kommentar als Docstring, + was bei Re-Reads nach Wochen die Wiedereinarbeit auf Minuten bringt.
    • +
  • Tests parametrisieren über ADAPTERS-Registry: ein einzelner + Test-Helper iteriert alle aktiven Adapter und prüft die Akzeptanz- + Kriterien (search liefert ≥3 Hits, get_document funktioniert, + download_text extrahiert Text).
    • +
  • Neue Bundesländer kommen als 100-300-Zeilen-Klasse + 1 Eintrag in + ADAPTERS rein, ohne Berührung anderer Adapter.
    • +
+

Negativ

+
    +
  • parlamente.py ist groß (~3000 Zeilen, 17 Klassen). Code-Navigation + via Grep statt Auto-Imports.
    • +
  • Reverse-Engineering-Findings sind in Kommentaren, nicht in einer + reference-Sektion. Wenn sich das System ändert, kann der Kommentar + veralten — Mitigation: jede Reverse-Engineering-Session legt einen + HAR-Trace in TEMP/ und referenziert ihn im Class-Docstring.
    • +
  • Adapter-Bugs leak nicht in andere Adapter, aber gemeinsame + Fraktion-Disambiguation muss manuell konsistent gehalten werden + (siehe #55-Refactor und seine Regression in Issue #60-Side-Befund: + ein Refactor-Rest in embeddings.py:528 wurde durch ein anderes + Modul verbreitet).
    • +
+

Folgen für andere ADRs

+
    +
  • ADR 0001 (LLM-Citation-Binding) ist davon unabhängig — der Postprocess + läuft adapter-agnostisch nach jedem analyze_antrag.
    • +
  • Eine künftige Module-Splitter-Entscheidung (adapters/ als Folder) + würde den ADR superseden, wenn parlamente.py über ~5000 Zeilen wächst.

0003 — Sub-D Property-Verification: Zitate als Substring der zitierten PDF-Seite

+ + + + + + + + + + + + + + + + + + + + + +
Statusaccepted
Datum2026-04-10
RefsIssues #50, #54, #60; tests/integration/test_citations_substring.py
+

Kontext

+

Der LLM-Output enthält pro Assessment N Zitate, jedes mit text, quelle +(z.B. "GRÜNE NRW Wahlprogramm 2022, S. 58") und url. Wahrscheinlich +korrekt — aber wie verifizieren wir das, ohne jedes einzeln händisch +nachzuschlagen?

+

Die naheliegenden Test-Optionen sind alle unbefriedigend:

+
    +
  • Mock-LLM-Tests: prüfen das Schema, sagen aber nichts über die + inhaltliche Korrektheit.
    • +
  • Snapshot-Tests der LLM-Outputs: drift mit jedem Modell-Update.
    • +
  • Manuelles Stichprobenchecken: skaliert nicht über mehrere BLs.
    • +
+

Optionen

+

Option A — Schema-only Tests (was wir vorher hatten)

+

Pydantic validiert dass jedes Zitat die Felder text, quelle, url hat +und url mit /static/referenzen/ beginnt. Erkennt syntaktische +Korruption, aber keine Halluzinationen.

+

Option B — Property-Test gegen die echten PDFs

+

Pro Zitat in der Prod-DB: +1. quelle per Token-Coverage-Match auf den PROGRAMME-Eintrag mappen. +2. Seitennummer aus quelle extrahieren. +3. Per fitz die PDF-Seite lesen, Whitespace + Soft-Hyphen normalisieren. +4. text muss als Substring (oder 5-Wort-Anker) in der Seite vorkommen. +5. Bug-Klasse 17 (Cross-Bundesland-Zitat): das aufgelöste Programm muss + zum Bundesland des Antrags passen, oder ein Grundsatzprogramm sein.

+

Vorteile: prüft die einzige Eigenschaft die wirklich zählt — "war +das was zitiert wird auch wirklich da". Findet Halluzinationen direkt.

+

Nachteile: braucht eine lokale Kopie der gwoe-antraege.db und der +Wahlprogramm-PDFs. Test ist Pydantic-Schema-übergreifend (Integration, +nicht Unit). Skipped sauber wenn DB nicht gemounted ist.

+

Option C — Online-Verifikation pro Assessment-Insert

+

Im analyze_antrag-Flow direkt nach LLM-Call jedes Zitat verifizieren +und bei Failure abbrechen oder retry.

+

Vorteile: kein "stale data in DB"-Risiko.

+

Nachteile: fügt Latenz und Komplexität in den Hot-Path. Die +Verifikation ist O(N×M), wo N=Zitate und M=Wahlprogramm-Pages.

+

Entscheidung

+

Option B als pytest-Integration-Test — tests/integration/test_citations_substring.py, +parametrisiert per _load_recent_assessments(limit_per_bl=5) × _flat_zitate().

+

Strict substring als Default-Match (Whitespace + Soft-Hyphen normalisiert, +LLM-Truncation-Marker ... toleriert), 5-Wort-Anker als Fallback für +geringfügige Wort-Drift wie "LLM hat mittendrin gekürzt". Min-Length-Guard +von 20 Zeichen verhindert false-positive Matches auf trivialen Snippets.

+

Marker pytestmark = pytest.mark.integration — der Test läuft nicht in +der Default-Suite, sondern explizit per pytest -m integration. Skipped +wenn webapp/data/gwoe-antraege.db nicht existiert (Dev-Setup ohne +DB-Kopie).

+

Match-Helpers (_normalize, _is_substring, _resolve_quelle_to_programm_id, +_extract_page_number) sind eigene Unit-Tests in TestHelpers — die Match- +Logik selbst ist nicht-trivial und braucht ihre Eigenkontrolle.

+

Konsequenzen

+

Positiv

+
    +
  • Findet Halluzinationen direkt: Issue #60 wurde durch den ersten + Live-Lauf dieses Tests entdeckt (3 von 36 Citations failed), ohne + dass ein Mensch Wahlprogramm-PDFs aufmachen musste.
    • +
  • Re-runnable als Regression-Gate: nach jedem Deploy einmal pytest -m + integration gegen die DB → 0 Failures = OK.
    • +
  • Test-Logik = Production-Logik: ADR 0001 Option B (reconstruct_zitate) + nutzt identische Match-Heuristiken (find_chunk_for_text, + _normalize_for_match). Damit kann der Test nichts fangen, was die + Production nicht auch fangen würde, und umgekehrt — kein Test-/Prod-Drift.
    • +
+

Negativ

+
    +
  • Lokale DB-Kopie nötig: vor jedem Sub-D-Run muss data/gwoe-antraege.db + vom Container gepullt werden. CI-Integration steht aus.
    • +
  • Test ist langsam-ish: ~50 Citations × ein PDF-Open pro Programm ist + bei den ~30 indexierten Programmen ~250ms im Ganzen, nicht trivial aber + nicht prohibitiv.
    • +
  • Token-Coverage-Heuristik für Quelle-zu-Programm-Mapping kann false- + positive bei sehr ähnlichen Programmen werden (z.B. CDU NRW 2022 vs. CDU + Niedersachsen 2022 — würde durch Bundesland-Bonus-Check abgefangen).
    • +
+

Folgen für andere ADRs

+
    +
  • ADR 0001 ist von ADR 0003 abhängig — wenn dieser Test entfernt würde, + hätte der LLM-Citation-Postprocess keinen Backstop und neue Halluzinations- + Bug-Klassen würden still durchrutschen.

0004 — Docker Compose Deploy mit DB-/Reports-Volume und SN-XML-Sonderpfad

+ + + + + + + + + + + + + + + + + + + + + +
Statusaccepted
Datum2026-04-10
RefsCLAUDE.md "Deployment", docker-compose.yml, Issue #5, project_sn_xml_export
+

Kontext

+

Der GWÖ-Antragsprüfer läuft als Docker-Container gwoe-antragspruefer auf +einem VServer hinter Traefik (Let's Encrypt SSL, Domain +gwoe.toppyr.de). Code wird via Git aus repo.toppyr.de gezogen.

+

Drei Subsysteme haben unterschiedliche Lebenszyklen:

+
    +
  1. Code (app/) — wird bei jedem Deploy neu kopiert.
    2. +
  2. SQLite-Daten (data/gwoe-antraege.db, data/embeddings.db) — + Source of Truth, MUSS persistent über Deploys hinweg.
    3. +
  3. PDF-Reports (reports/*.pdf) — sind generierte Artefakte, könnten + theoretisch regeneriert werden, sind aber teuer (LLM-Calls + WeasyPrint), + also auch persistent.
    4. +
+

Issue #5 hatte einen frühen Schmerzpunkt: der Container-Build hat die +DB überschrieben, weil data/ nicht aus dem Build-Context exkludiert war.

+

Optionen

+

Option A — Alles im Image, manuelle Backups

+

Code, DB, Reports zusammen im Image. Backups via docker cp vor jedem +Deploy.

+

Nachteile: Image wird gigantisch, jeder Deploy ist ein Risk-Event, +kein automatischer Persistenz-Mechanismus.

+

Option B — Docker-Volumes für DB und Reports

+

docker-compose.yml mountet ./data und ./reports vom Host als Volumes. +Build kopiert nur app/ und requirements.txt.

+

Vorteile: Host-Volumes überleben Container-Restart und Image-Rebuild. +Backups via Standard-Linux-Tools auf dem Host.

+

Nachteile: Build-Context muss data/, reports/, .env exkludieren +(siehe .dockerignore), sonst werden sie versehentlich ins Image kopiert +und überschreiben das gemountete Volume bei Container-Start.

+

Option C — Externe DB (Postgres)

+

Postgres als separater Container, gwoe-antragspruefer verbindet per asyncpg.

+

Vorteile: standard, robust, Backups via pg_dump.

+

Nachteile: Migration aller existierenden Queries, neue Abhängigkeit, +mehr Operational Surface. SQLite reicht für die aktuelle Last (~30 Anträge, +selten parallele Writes).

+

Entscheidung

+

Option B. Docker-Compose mit Host-Volumes für data/ und reports/. +.dockerignore exkludiert beide aus dem Build-Context.

+

Standard-Deploy

+
ssh vserver 'cd /opt/gwoe-antragspruefer && git pull && docker compose up -d --build'
+
+

Manueller Tar-Upload (falls Git-Workflow blockiert ist)

+
cd webapp
+tar czf /tmp/gwoe-webapp.tar.gz \
+  --exclude='venv' --exclude='__pycache__' \
+  --exclude='data' --exclude='reports' --exclude='.env' .
+scp /tmp/gwoe-webapp.tar.gz vserver:/tmp/
+ssh vserver 'cd /opt/gwoe-antragspruefer && tar xzf /tmp/gwoe-webapp.tar.gz && docker compose up -d --build'
+
+

Beachte: --exclude='data' ist zwingend, sonst überschreibt der Tar +die Live-DB.

+

SN-XML-Sonderpfad

+

Sachsen hat keinen scrape-baren Endpoint und liest stattdessen wöchentlich +manuell exportierte XML-Dumps aus EDAS. Workflow:

+
    +
  1. User exportiert XML aus EDAS (manuell, im Browser).
    2. +
  2. cp dokumente_export.xml gwoe-antragspruefer:/app/data/sn-edas/
    3. +
  3. scp aus dem Container ins Host-Volume — kein Container-Restart nötig.
    4. +
  4. SNEdasXmlAdapter liest die XML beim nächsten Search-Call.
    5. +
+

Details in ~/.claude/projects/<projekt>/memory/project_sn_xml_export.md.

+

Container-Zeitzone

+

Der Container läuft UTC, nicht CEST. DB-Timestamps in assessments.created_at +sind UTC (kein TZ-Suffix, aber UTC). Beim Korrelieren mit Commit-Zeiten +(lokal CEST = UTC+2) muss konvertiert werden, sonst fließen falsche +Schlussfolgerungen ein. Detailliert in +~/.claude/projects/<projekt>/memory/reference_container_utc.md.

+

Konsequenzen

+

Positiv

+
    +
  • DB überlebt jeden Deploy — verifiziert seit Issue #5 (Fix in + .dockerignore-Update).
    • +
  • Backups sind trivial: tar czf gwoe-data-$(date +%F).tar.gz data/ + auf dem Host.
    • +
  • Build ist schnell (~30s für nicht-cached Layers), weil das Image + nur Code + Dependencies enthält.
    • +
+

Negativ

+
    +
  • .dockerignore ist ein Foot-Gun — wenn jemand vergisst, data/ neu + hinzuzufügen nach einem Refactor, kann es passieren dass der Build die + Live-DB überschreibt. Mitigation: ein dedicated Sub-D-style Test, der + nach dem Build prüft, dass die DB die erwarteten Tabellen hat — steht + noch aus.
    • +
  • SN-XML braucht manuelle Pflege wöchentlich. Akzeptiert weil es kein + scrape-baren Endpoint gibt.
    • +
  • SQLite skaliert nicht über parallele Writes — bei mehr als ~5 + gleichzeitigen Analyses würde es Lock-Contention geben. Aktuell läuft + alles seriell durch den Background-Task-Mechanismus, also kein Problem. + Bei Wachstum auf >50 Analyses/Tag wäre ein Postgres-Migration ein + separater ADR.
    • +
+

Folgen für andere ADRs

+
    +
  • ADR 0002 (Adapter-Architektur) ist davon unabhängig — Adapter sind reine + Code-Klassen ohne State.
    • +
  • Ein zukünftiger Postgres-Migration-ADR würde diesen ADR partial superseden + (DB-Persistenz, nicht Reports).

Architecture Decision Records (ADRs)

+

ADRs dokumentieren signifikante Architektur-Entscheidungen mit Kontext, Optionen +und Konsequenzen. Format inspiriert von Michael Nygard.

+

Workflow

+
    +
  1. Neue Entscheidung steht an → Kopie von template.md mit nächster freier + Nummer (NNNN-kebap-titel.md).
    2. +
  2. Status proposed → diskutiert in Issue/PR → bei Akzeptanz auf accepted.
    3. +
  3. Niemals editieren nach accepted. Wenn eine Entscheidung sich ändert, + neuer ADR mit Supersedes: NNNN-… im Header und der alte ADR bekommt + Superseded by: MMMM-….
    4. +
  4. Status deprecated für Entscheidungen, die ohne Nachfolger auslaufen.

1. Überblick

+

Der GWÖ-Antragsprüfer bewertet parlamentarische Anträge (aktuell: NRW Landtag) systematisch nach drei Dimensionen:

+
    +
  1. GWÖ-Treue (0-10): Übereinstimmung mit der Gemeinwohl-Ökonomie Matrix 2.0
    2. +
  2. Wahlprogrammtreue (0-10): Konsistenz mit dem NRW-Wahlprogramm 2022 der einreichenden Fraktion(en) und der Fraktionen in Regierungsverantwortung
    3. +
  3. Parteiprogrammtreue (0-10): Konsistenz mit dem Grundsatzprogramm der einreichenden Fraktion(en) und der Fraktionen in Regierungsverantwortung
    4. +
+

Das Tool generiert professionelle PDF-Berichte mit dem offiziellen ECOnGOOD-Branding.

+
+

2. Gewählte Matrix: V2.0 für Gemeinden

+

Warum nicht Matrix 5.1?

+

Die GWÖ-Matrix 5.1 ist für Unternehmen konzipiert mit Berührungsgruppen wie "Kund:innen", "Eigentümer:innen", "Mitarbeitende". Diese passen nicht zu parlamentarischen Anträgen.

+

Warum nicht Matrix 2.1.A?

+

Die Matrix 2.1.A ist für die "öffentliche Hand" allgemein. Die Matrix 2.0 für Gemeinden bietet einen etwas weiteren Blick und ist kompakter formuliert — ideal für parlamentarische Analyse.

+

+

Relevanz für Landesanträge

+

Die meisten Parlamentsanträge betreffen: +- D-Zeile: Wirkung auf Bürger:innen und Wirtschaft im Land +- E-Zeile: Überregionale oder langfristige Auswirkungen

+

Prinzip: D (intern) hat Vorrang vor E (extern).

+
+

3. Programmtreue-Bewertung

+

Zwei Dimensionen

+

Anträge werden sowohl gegen das Wahlprogramm als auch gegen das Grundsatzprogramm der Fraktionen geprüft:

Archiv

+

Hier liegen historische Doku-Snapshots, die nicht mehr autoritativ sind. +Sie beschreiben jeweils einen Zustand zu einem bestimmten Zeitpunkt; vieles +davon ist heute überholt.

+

Warum nicht löschen?

+
    +
  • Sie sind als historische Quelle nützlich, wenn man verstehen will, wie + das Projekt zu einem früheren Zeitpunkt strukturiert war.
    • +
  • Manche Findings sind in die ADRs (../adr/) übernommen, andere bewusst + nicht — weil sie tagesaktueller Stand waren und nie ADR-würdig.

DateiStandBeschreibung
DOKUMENTATION-2026-03-24.md2026-03-24Frühe Skript-basierte Architektur, vor dem Webapp-Migrate. Beschreibt scripts/process_single.sh-Workflow, der heute durch FastAPI-Backend ersetzt ist.
STATUS-2026-03-28.md2026-03-28Tagesstand-Snapshot. Beschreibt v5-Prompt, Persistenz-Volume, Security-Headers — alle drei sind heute Standard.
README-2026-03-28.md2026-03-28Erste Repo-README. Listet nur den NRW-Adapter (vor #2/#3/#4 und 13 weiteren BLs). Architektur-Diagramm ist veraltet.
+

Wenn etwas davon noch wahr ist…

+

…gehört es in einen ADR (../adr/) oder die generierte Reference (geplant +für #62 Phase 2). Bitte nicht in einen neuen Status-Snapshot ziehen. +Status-Snapshots sind die Drift-Falle, die wir hier vermeiden wollen.

It\n * might be for example a function that you passed to Observable's constructor, but most of the time it is\n * a library implementation, which defines what will be emitted by an Observable, and when it be will emitted. This means\n * that calling `subscribe` is actually the moment when Observable starts its work, not when it is created, as it is often\n * the thought.\n *\n * Apart from starting the execution of an Observable, this method allows you to listen for values\n * that an Observable emits, as well as for when it completes or errors. You can achieve this in two\n * of the following ways.\n *\n * The first way is creating an object that implements {@link Observer} interface. It should have methods\n * defined by that interface, but note that it should be just a regular JavaScript object, which you can create\n * yourself in any way you want (ES6 class, classic function constructor, object literal etc.). In particular, do\n * not attempt to use any RxJS implementation details to create Observers - you don't need them. Remember also\n * that your object does not have to implement all methods. If you find yourself creating a method that doesn't\n * do anything, you can simply omit it. Note however, if the `error` method is not provided and an error happens,\n * it will be thrown asynchronously. Errors thrown asynchronously cannot be caught using `try`/`catch`. Instead,\n * use the {@link onUnhandledError} configuration option or use a runtime handler (like `window.onerror` or\n * `process.on('error)`) to be notified of unhandled errors. Because of this, it's recommended that you provide\n * an `error` method to avoid missing thrown errors.\n *\n * The second way is to give up on Observer object altogether and simply provide callback functions in place of its methods.\n * This means you can provide three functions as arguments to `subscribe`, where the first function is equivalent\n * of a `next` method, the second of an `error` method and the third of a `complete` method. Just as in case of an Observer,\n * if you do not need to listen for something, you can omit a function by passing `undefined` or `null`,\n * since `subscribe` recognizes these functions by where they were placed in function call. When it comes\n * to the `error` function, as with an Observer, if not provided, errors emitted by an Observable will be thrown asynchronously.\n *\n * You can, however, subscribe with no parameters at all. This may be the case where you're not interested in terminal events\n * and you also handled emissions internally by using operators (e.g. using `tap`).\n *\n * Whichever style of calling `subscribe` you use, in both cases it returns a Subscription object.\n * This object allows you to call `unsubscribe` on it, which in turn will stop the work that an Observable does and will clean\n * up all resources that an Observable used. Note that cancelling a subscription will not call `complete` callback\n * provided to `subscribe` function, which is reserved for a regular completion signal that comes from an Observable.\n *\n * Remember that callbacks provided to `subscribe` are not guaranteed to be called asynchronously.\n * It is an Observable itself that decides when these functions will be called. For example {@link of}\n * by default emits all its values synchronously. Always check documentation for how given Observable\n * will behave when subscribed and if its default behavior can be modified with a `scheduler`.\n *\n * #### Examples\n *\n * Subscribe with an {@link guide/observer Observer}\n *\n * ```ts\n * import { of } from 'rxjs';\n *\n * const sumObserver = {\n * sum: 0,\n * next(value) {\n * console.log('Adding: ' + value);\n * this.sum = this.sum + value;\n * },\n * error() {\n * // We actually could just remove this method,\n * // since we do not really care about errors right now.\n * },\n * complete() {\n * console.log('Sum equals: ' + this.sum);\n * }\n * };\n *\n * of(1, 2, 3) // Synchronously emits 1, 2, 3 and then completes.\n * .subscribe(sumObserver);\n *\n * // Logs:\n * // 'Adding: 1'\n * // 'Adding: 2'\n * // 'Adding: 3'\n * // 'Sum equals: 6'\n * ```\n *\n * Subscribe with functions ({@link deprecations/subscribe-arguments deprecated})\n *\n * ```ts\n * import { of } from 'rxjs'\n *\n * let sum = 0;\n *\n * of(1, 2, 3).subscribe(\n * value => {\n * console.log('Adding: ' + value);\n * sum = sum + value;\n * },\n * undefined,\n * () => console.log('Sum equals: ' + sum)\n * );\n *\n * // Logs:\n * // 'Adding: 1'\n * // 'Adding: 2'\n * // 'Adding: 3'\n * // 'Sum equals: 6'\n * ```\n *\n * Cancel a subscription\n *\n * ```ts\n * import { interval } from 'rxjs';\n *\n * const subscription = interval(1000).subscribe({\n * next(num) {\n * console.log(num)\n * },\n * complete() {\n * // Will not be called, even when cancelling subscription.\n * console.log('completed!');\n * }\n * });\n *\n * setTimeout(() => {\n * subscription.unsubscribe();\n * console.log('unsubscribed!');\n * }, 2500);\n *\n * // Logs:\n * // 0 after 1s\n * // 1 after 2s\n * // 'unsubscribed!' after 2.5s\n * ```\n *\n * @param observerOrNext Either an {@link Observer} with some or all callback methods,\n * or the `next` handler that is called for each value emitted from the subscribed Observable.\n * @param error A handler for a terminal event resulting from an error.
