Model benchmark: testaa kaikki Ollama-mallit järjestelmällisesti

Ajaa täyden pipeline-kierroksen per malli × skenaario:
1. Client-prompti → vaatimukset
2. Manager/SPEC_SYSTEM → JSON-speksi
3. Template-generointi → koodi
4. Validointi + LLM-korjaussilmukka
5. uv sync + pytest

Tuottaa vertailutaulukon: speksin laatu, testien tulos, nopeus.
Tukee suoraa Ollamaa (--ollama) ja hub-reittiä (--hub).

+# Templating — rakennuspalaset koodigeneroinnissa
+
+## Perusperiaate
+
+Kielimalli päättää **mitä** rakennetaan (entiteetit, kentät, tyypit, yhteydet).
+Template-funktiot päättävät **miten** se rakennetaan (importit, engine setup, testikonfiguraatio).
+
+```
+Projektikuvaus → LLM → JSON-speksi → Templateit → Koodi → Validointi
+```
+
+LLM:n kontribuutio on yksi JSON-rakenne. Kaikki muu on determinististä —
+sama speksi tuottaa aina saman koodin.
+
+## Miksi tämä toimii
+
+Pienen kielimallin (0.5B–7B) vahvuudet ja heikkoudet ovat epäsymmetrisiä:
+
+| Tehtävä | LLM:n kyky | Ratkaisu |
+|---------|-----------|----------|
+| Tunnista entiteetit kuvauksesta | Hyvä | LLM tekee |
+| Valitse kenttätyypit | Hyvä | LLM tekee |
+| Muista importit oikein | Huono | Template tekee |
+| SQLite connect_args | Huono | Template tekee |
+| Testikonfiguraatio | Huono | Template tekee |
+| Dockerfile-rakenne | Huono | Template tekee |
+
+Annetaan mallin tehdä se missä se on hyvä. Hoidetaan loput mekaanisesti.
+
+## JSON-speksi
+
+Kielimallin ainoa tuotos on JSON joka kuvaa projektin rakenteen:
+
+```json
+{
+  "project_name": "library-app",
+  "entities": [
+    {
+      "name": "Author",
+      "table_name": "authors",
+      "fields": [
+        {"name": "name", "sa_type": "String(255)", "py_type": "str", "nullable": false, "default": null}
+      ]
+    },
+    {
+      "name": "Book",
+      "table_name": "books",
+      "fields": [
+        {"name": "title", "sa_type": "String(255)", "py_type": "str", "nullable": false, "default": null},
+        {"name": "author_id", "sa_type": "Integer", "py_type": "int", "nullable": false, "default": null}
+      ]
+    }
+  ],
+  "relationships": [
+    {"from": "Book", "field": "author_id", "to": "Author", "type": "many-to-one"}
+  ],
+  "extra_imports": []
+}
+```
+
+Speksin laatu ratkaisee kaiken. Hyvä speksi → hyvä projekti. Huono speksi →
+teknisesti toimiva mutta sisällöllisesti väärä projekti.
+
+## Architect-promptin rooli
+
+Architect-agentti (JSON-speksin generoija) on kriittisin kohta koko pipelinessa.
+Sitä ohjataan neljällä keinolla:
+
+1. **Chain-of-thought** — malli miettii ensin entiteetit, sitten kentät,
+   sitten yhteydet, vasta lopuksi JSON
+2. **Domain-esimerkit** — Todo, verkkokauppa, blogi — malli näkee miltä
+   hyvä speksi näyttää eri domaineissa
+3. **Anti-patternit** — turhat ID-kentät, Enum-tyypit, suomenkieliset nimet
+4. **Yhteyssäännöt** — jokainen `_id`-kenttä tarvitsee relationship-merkinnän
+
+Isompi malli tässä yhdessä kohdassa parantaisi kaikkien projektien laatua.
+
+## Templateit
+
+Jokainen template on funktio joka ottaa speksin ja palauttaa koodia:
+
+```
+tmplModels(spec)     → models.py      (SQLAlchemy, ForeignKey, relationship)
+tmplSchemas(spec)    → schemas.py     (Pydantic Create/Response/Detail)
+tmplMain(spec)       → main.py        (FastAPI CRUD + nested endpoints + FK-validointi)
+tmplTests(spec)      → test_main.py   (pytest + TestClient + helper-funktiot)
+tmplPyproject(spec)  → pyproject.toml (PEP 621)
+tmplDockerfile()     → Dockerfile     (uv + non-root user)
+```
+
+Templateit generoivat automaattisesti:
+- ForeignKey-constraintit ja relationship()-määrittelyt
+- Nested endpointit (`GET /authors/{id}/books/`)
+- FK-validointi (404 jos parent-entiteettiä ei ole)
+- Detail-schemat (Book + author-data mukana)
+- Test-helperit jotka luovat parent-entiteetit ensin
+- Bad FK -testit (varmistaa että orpo-validointi toimii)
+
+## Validointi
+
+Generoitu koodi validoidaan mekaanisesti ennen käyttöä:
+
+- Syntaksitarkistus (AST parse)
+- Projektin sisäiset importit (löytyykö nimi lähdetiedostosta)
+- SQLite connect_args
+- Relatiiviset importit (kielletty)
+- Testien rakenne (ei saa kopioida appia)
+- pyproject.toml (ei poetryä)
+- Dockerfile (ei poetryä, uv cache -oikeudet)
+
+Docker-testi ajaa koko projektin: build → pytest → API smoke test.
+
+## Rajoitukset
+
+Templateit kattavat rakenteellisesti tunnetut projektit:
+
+| Stack | Kattavuus |
+|-------|-----------|
+| FastAPI + SQLAlchemy CRUD | Toimii hyvin |
+| Streamlit + DuckDB dashboard | Toimii hyvin |
+| Muu | Ei templatea → ei toimi |
+
+**Ei kata:**
+- Custom business-logiikka (algoritmit, laskenta, ML)
+- Epätyypilliset arkkitehtuurit (WebSocket, graafit, tapahtumapohjaiset)
+- Frontend-sovellukset (React, Vue)
+- Mikä tahansa mitä template ei tunne
+
+Arvio: templateit kattavat ~20% kaikista mahdollisista projekteista, mutta juuri
+sen 20% mitä opiskelu- ja prototyyppiympäristöissä tarvitaan useimmin.
+
+## Laajentaminen
+
+Uuden stackin lisääminen vaatii:
+
+1. Uudet template-funktiot (käsityö, ~200–400 riviä per stack)
+2. JSON-speksin laajennos (uudet kentät jos tarvitaan)
+3. Validointisäännöt uudelle stackille
+4. Docker-testikonfiguraatio
+
+Jokainen template on staattinen — se ei opi eikä sopeudu. Kattavuus kasvaa
+vain kirjoittamalla lisää templateja.
+
+## Hybridi: seuraava askel
+
+Paras lopputulos syntyisi yhdistelmällä:
+
+```
+Speksi → Template (runko) → LLM (business-logiikka) → Validointi
+```
+
+Template tuottaa toimivan CRUD-pohjan. LLM lisää domain-kohtaisen logiikan
+pienissä palasissa (yksi funktio kerrallaan). Mekaaninen validointi
+tarkistaa jokaisen lisäyksen.
+
+Tämä palauttaa LLM:n epäluotettavuuden takaisin peliin, mutta rajattuna:
+virheet ovat paikallisia (yksi funktio) eivätkä rakenteellisia (koko projekti).

+## Rakennuspalaset vs. vapaa generointi
+
+Kielimalli voi generoida koodia kahdella perustavanlaatuisesti eri tavalla.
+Ymmärtäminen milloin kumpikin toimii on avain luotettavaan koodigenerointi-pipelineen.
+
+### Tapa 1: Vapaa generointi (naivi)
+
+LLM generoi jokaisen tiedoston tyhjästä. Prompti kuvaa mitä halutaan,
+malli tuottaa koko tiedoston — importeista lähtien.
+
+```mermaid
+flowchart LR
+    P["Prompti"] --> LLM1["LLM: models.py"]
+    LLM1 --> V1{"Validointi"}
+    V1 -->|virhe| LLM1
+    V1 -->|ok| LLM2["LLM: schemas.py"]
+    LLM2 --> V2{"Validointi"}
+    V2 -->|virhe| LLM2
+    V2 -->|ok| LLM3["LLM: main.py"]
+    LLM3 --> V3{"..."}
+
+    style V1 fill:#1a1e2e,stroke:#f85149,color:#c9d1d9
+    style V2 fill:#1a1e2e,stroke:#f85149,color:#c9d1d9
+    style V3 fill:#1a1e2e,stroke:#f85149,color:#c9d1d9
+```
+
+**Ongelma:** Pieni malli (0.5B–7B) tekee toistuvia rakenteellisia virheitä:
+
+| Virhe | Esiintymistiheys | Selitys |
+|-------|:---:|------|
+| Puuttuva import | ~60% | `from datetime import date` unohtuu |
+| SQLite `connect_args` | ~80% | Malli ei muista SQLite-erityisyyttä |
+| Väärä Enum-käyttö | ~50% | Sekoittaa `sqlalchemy.Enum` ja `enum.Enum` |
+| Poetry pyproject.toml:ssa | ~40% | Malli suosii Poetryä vaikka ohje sanoo uv |
+| Testit kopioivat koko appin | ~70% | Malli ei osaa importata, luo uudet reitit |
+
+Retry-loopilla (virhe → uusi yritys virheviestin kanssa) osa korjautuu,
+mutta **sama malli toistaa samoja virheitä** koska ne johtuvat harjoitusdatasta.
+7 tiedoston projekti vaatii 7–14 LLM-kutsua ja 80–120 sekuntia.
+
+### Tapa 2: Rakennuspalaset (template pipeline)
+
+LLM:ltä pyydetään **vain JSON-speksi** — entiteetit, kentät ja tyypit.
+Koodi kootaan mekaanisesti valmiista pohjista joiden rakenne on todistettavasti
+oikein.
+
+```mermaid
+flowchart LR
+    P["Projektin kuvaus"] --> LLM["LLM: JSON-speksi"]
+    LLM --> S["{ entities: [...] }"]
+    S --> T1["Template: models.py"]
+    S --> T2["Template: schemas.py"]
+    S --> T3["Template: main.py"]
+    S --> T4["Template: test_main.py"]
+    S --> T5["Template: Dockerfile"]
+    T1 & T2 & T3 & T4 & T5 --> D["Docker build + pytest"]
+
+    style LLM fill:#1a1e2e,stroke:#d29922,color:#c9d1d9
+    style S fill:#1a1e2e,stroke:#3fb950,color:#c9d1d9
+    style D fill:#1a1e2e,stroke:#58a6ff,color:#c9d1d9
+```
+
+**Idea:** Malli on hyvä päättämään *mitä* (entiteetit, kentät), mutta huono
+muistamaan *miten* (importit, engine setup, testikonfiguraatio). Annetaan
+mallin tehdä se missä se on hyvä, ja hoidetaan loput mekaanisesti.
+
+### LLM:n ainoa tehtävä
+
+Malli tuottaa JSON-rakenteen kuten:
+
+```json
+{
+  "project_name": "todo-app",
+  "entities": [
+    {
+      "name": "Todo",
+      "table_name": "todos",
+      "fields": [
+        {"name": "title", "sa_type": "String(255)", "py_type": "str", "nullable": false},
+        {"name": "due_date", "sa_type": "Date", "py_type": "date | None", "nullable": true},
+        {"name": "status", "sa_type": "String(20)", "py_type": "str", "default": "pending"}
+      ]
+    }
+  ],
+  "extra_imports": ["from datetime import date"]
+}
+```
+
+Tämä on yksinkertainen tehtävä jossa pienikin malli onnistuu luotettavasti:
+entiteettien tunnistus projektin kuvauksesta ja kenttätyyppien valinta.
+
+Speksi sisältää myös **taulujen väliset yhteydet** (relationships):
+
+```json
+{
+  "entities": [
+    {"name": "Author", "table_name": "authors", "fields": [...]},
+    {"name": "Book", "table_name": "books", "fields": [
+      {"name": "title", "sa_type": "String(255)", "py_type": "str", "nullable": false},
+      {"name": "author_id", "sa_type": "Integer", "py_type": "int", "nullable": false}
+    ]}
+  ],
+  "relationships": [
+    {"from": "Book", "field": "author_id", "to": "Author", "type": "many-to-one"}
+  ]
+}
+```
+
+Templateit generoivat yhteyksistä automaattisesti:
+- `ForeignKey('authors.id')` models.py:hin
+- `relationship("Book", back_populates="author")` molempiin suuntiin
+- `BookDetail`-schema jossa author-data mukana
+- `GET /authors/{id}/books/` nested endpoint
+- FK-validointi: 404 jos parent-entiteettiä ei ole
+
+### Architect-agentti: speksin laatu ratkaisee
+
+Arkkitehti on **kriittisin agentti** koko pipelinessa. Jos speksi on hyvä
+(oikeat taulut, kentät, yhteydet), kaikki muu seuraa automaattisesti.
+Jos speksi on huono, templateitkaan eivät pelasta.
+
+Arkkitehtia ohjataan:
+1. **Chain-of-thought**: "Mieti ensin taulut, sitten kentät, sitten yhteydet"
+2. **Domain-esimerkit**: Todo, verkkokauppa, blogi — malli näkee miltä hyvä speksi näyttää
+3. **Anti-patternit**: "Ei turhia ID-kenttiä, ei Enumeita, ei suomenkielisiä nimiä koodissa"
+4. **Yhteyssäännöt**: "Jokainen `_id`-kenttä tarvitsee vastaavan relationship-merkinnän"
+
+Isompi malli (tai API) tässä yhdessä kohdassa parantaa kaikkien projektien laatua
+koska speksi on ainoa paikka jossa LLM:n ymmärrys vaikuttaa.
+
+### Template täyttää loput
+
+Jokainen template on kuin madlib — aukot täytetään speksin datalla:
+
+**models.py template (yksinkertaistettu):**
+```python
+from sqlalchemy import create_engine, Column, Integer, {sa_types}, ForeignKey
+from sqlalchemy.orm import sessionmaker, relationship
+# ... aina samat importit, engine setup, SessionLocal ...
+
+class {entity.name}(Base):
+    __tablename__ = "{entity.table_name}"
+    id = Column(Integer, primary_key=True, index=True)
+    {field.name} = Column({field.sa_type}, nullable={field.nullable})
+    # FK-kentät: ForeignKey + relationship automaattisesti
+    {fk_field} = Column(Integer, ForeignKey('{parent_table}.id'))
+    {parent_lower} = relationship("{Parent}", back_populates="{children}")
+```
+
+Tulos: importit ovat aina oikein, `connect_args` on aina mukana,
+taulujen yhteydet generoituvat oikein, testit importoivat `main.py`:stä eivätkä kopioi sitä.
+
+### Vertailu: mittaustulokset
+
+| | Vapaa generointi | Rakennuspalaset |
+|---|:---:|:---:|
+| LLM-kutsuja | 7–14 | **3** (speksi + requirements + README) |
+| Aika | 80–120s | **~25s** |
+| Syntaksi OK | ~70% | **100%** |
+| Docker build | vaihteleva | **100%** |
+| Pytest läpi | 0% | **100%** |
+| API toimii | ~30% | **100%** |
+| Taulujen yhteydet (FK) | ei koskaan | **100%** |
+| Nested endpointit | ei koskaan | **automaattisesti** |
+
+### Milloin kumpikin toimii
+
+**Rakennuspalaset** kun:
+- Projektin rakenne on tunnettu (FastAPI + SQLAlchemy CRUD)
+- Laatu ja luotettavuus ovat tärkeitä
+- Malli on pieni (0.5B–7B)
+
+**Vapaa generointi** kun:
+- Projektin rakenne on epätavallinen
+- Tarvitaan custom-logiikkaa jota template ei kata
+- Malli on riittävän iso (>70B tai pilvi-API)
+
+Paras lopputulos syntyy yhdistelmällä: **rakennuspalaset perusrakenteelle,
+vapaa generointi business-logiikalle**.
