<issue_description># PR 90: Akademia – trenowanie/fine-tuning modeli z poziomu UI

Aktualizacja (2026-02-11)

Dokument doprecyzowano pod realizację w bieżącej architekturze (FastAPI + web-next) i obecnych bramkach jakości (make pr-fast, make check-new-code-coverage, make sonar-reports).
Najważniejsza zmiana: etapowanie na bezpieczne MVP + fazy rozszerzające.
Agent kodowania musi zapoznać się z całym zakresem i rozpisać na odpowiednie PR. Całość ma być zrealizowane na jednej gałęzi.

Cel

Wprowadzić brakujący element strategii Venom: użytkownik ma móc przygotować dataset, uruchomić trening (LoRA/QLoRA) i aktywować nowy adapter z poziomu aplikacji. Zakres obejmuje brakujące zależności ML, API do orkiestracji treningu oraz nowy ekran w web-next do kontroli procesu.

Stan obecny (as-is)

Backend ma szkielety uczenia (venom_core/agents/professor.py, venom_core/infrastructure/gpu_habitat.py, venom_core/learning/dataset_curator.py, venom_core/core/model_manager.py), ale nie są podłączone do cyklu życia aplikacji (main.py ich nie inicjalizuje) ani do API/dispatcherów. Brak endpointów do datasetu/treningu/statusu/aktywizacji adaptera.
Konfiguracja zawiera klucze Academy (config.py, services/config_manager.py) i są widoczne w panelu konfiguracji (web-next/components/config/parameters-panel.tsx), jednak UI nie ma ekranu sterowania treningiem ani podglądu datasetów/logów.
Brak zależności do treningu w requirements.txt (unsloth/trl/peft/datasets/bitsandbytes + ewentualne cuda wheels), więc ścieżka GPUHabitat → Unsloth nie wystartuje.
Brak persystentnej historii treningów/adapters (tylko pamięć w procesie w Professor.training_history), brak mapowania adapterów do ModelManager/LLM runtime.
Brak strumieniowania logów z kontenerów treningowych; brak testów integracyjnych end-to-end (dataset → trening → aktywacja adaptera).

Zakres PR

Backend: pełne API Academy (dataset, trening, statusy, listy modeli/adapterów, aktywacja).
Infrastruktura: zależności ML i sanity-check środowiska (GPU/nvidia-toolkit, fallback CPU).
UI: ekran Academy w web-next (dataset stats, przycisk „Start training”, logi, lista adapterów + aktywacja).
Observability i bezpieczeństwo: log stream (SSE/WebSocket), walidacja parametrów, limity zasobów.
Dokumentacja i testy (unit + E2E scenariusz start/monitor/aktywacja).

Zakres MVP (must-have, pierwsze wdrożenie)

API i UI dla cyklu: dataset -> start train -> status -> activate adapter.
Trwałość stanu jobów i adapterów po restarcie backendu.
Walidacja parametrów wejściowych i czytelne błędy (brak GPU, brak zależności, timeout joba).
Aktywacja adaptera przez warstwę model/runtime z rollbackiem do modelu bazowego.

Poza MVP (kolejne PR-y)

Zaawansowane profile treningowe i auto-tuning hiperparametrów.
Rozbudowane porównania jakości modeli (benchmark suites).
Wielowęzłowy/distributed training.

Decyzje implementacyjne (doprecyzowanie)

Zależności treningowe nie trafiają do bazowego requirements.txt.
Utrzymujemy je jako profil opcjonalny (np. osobny requirements lub extras), aby nie destabilizować instalacji core.
API Academy domyślnie tylko localhost/admin path.
Endpointy startujące trening i aktywację adapterów traktujemy jako operacje administracyjne.
Źródło prawdy dla jobów:
- metadane: data/training/jobs.jsonl,
- log tail: pliki per job lub stream z agregacją,
- status końcowy: sukces/porażka + kod błędu.
Minimalny kontrakt statusu joba:
queued | preparing | running | finished | failed | cancelled.

Plan realizacji

Zależności i środowisko
- Dodać do requirements.txt pakiety treningowe (unsloth, trl, peft, datasets, bitsandbytes) z uwagami o wersjach CUDA; uaktualnić README/.env.example o wymogi nvidia-container-toolkit i opcje CPU fallback.
- W GPUHabitat dodać szybki self-check (brak Docker/GPU → zwrot controllera z komunikatem, skip start).
Backend API (FastAPI)
- Zainicjalizować DatasetCurator + GPUHabitat + Professor + ModelManager w main.py (gdy ENABLE_ACADEMY), przekazać LessonsStore.
- Nowy router api/routes/academy.py z operacjami: POST /dataset (kuracja + statystyki), POST /train (start job), GET /train/{job}/status (status + tail logów), GET /adapters (lista/metadata), POST /adapters/activate (hot-swap przez ModelManager/LLM router).
- Zapisać historię jobów (JSONL w data/training/jobs.jsonl + metadane adapterów), aby UI miało źródło prawdy po restarcie.
- Integracja z ModelManager/LLMServerController: możliwość aktywacji adaptera (PEFT) oraz rollback do bazowego modelu.
UI web-next
- Nowy widok „Academy” (np. /academy) z sekcjami: statystyki LessonsStore/dataset, przycisk kuracji, formularz parametrów treningu (prefill ...

@copilot niska jakos testow brak pokrycia na poziomie 80 procent
bledy w testach "=================================== FAILURES ===================================
___________________ tes...

Coverage is at 72% because the current 24 tests don't execute enough code paths, especially in gpu_habitat.py (only 6.2% covered - 2/32 lines).

The issue: Most GPUHabitat methods (get_gpu_info, stream_job_logs, cleanup_job) aren't being called by the existing tests. The tests mock these methods instead of testing them.

To reach 80%, we need to either:

Add tests that actually call GPUHabitat methods (not just mock them)
Add more Academy endpoint tests that trigger different code paths
Mark untestable code with # pragma: no cover

The current 24 tests are working correctly but provide insufficient coverage. Would you like me to add focused tests for the uncovered GPUHabitat methods and Academy code paths?

Analyzing coverage gaps and preparing targeted tests:

Critical Coverage Gaps:

gpu_habitat.py: 6.2% (2/32 lines) - Missing tests for:
- get_gpu_info() with actual Docker calls
- stream_job_logs() implementation
- cleanup_job() with container removal
academy.py: 70.3% (234/333 lines) - Missing paths:
- SSE streaming edge cases
- Error handling in training operations
- Adapter metadata parsing

Strategy:
Will add 8-10 lightweight mock-based tests focusing on:

GPUHabitat methods (mocking Docker client, not actual containers)
Academy API error paths (validation, not found, conflicts)
Edge cases (empty responses, malformed data)

These tests will use proper mocks to avoid heavy dependencies while maximizing coverage. Working on implementation now.

- fix Academy dashboard prop contract and strict status typings - update status badges/log viewer for canonical lifecycle values - resolve build-time TS issues in academy/brain views - add Playwright Academy smoke test for start/monitor/activate flow

- cover mutating endpoint guards and canonical status transitions - add Academy API edge cases (SSE stream, adapter list/activation, error paths) - verify GPU fallback behavior and cleanup status expectations - add main/model-manager tests for active adapter restore persistence

- remove importorskip guards that skipped gpu_habitat suites on runners without docker python package - add lightweight docker stubs for tests and replace docker.errors imports with module-safe exceptions - keep gpu_habitat changed-lines coverage above CI threshold

Replace synchronous open() in list_adapters with anyio.Path.read_text to satisfy async IO scanner rule.

- enforce adapter path derivation from adapter_id in Academy API - stop logging user-controlled identifiers/paths in ModelManager - constrain GPUHabitat dataset/output resolution to Academy base dirs - replace parseInt/parseFloat with Number.parseInt/Number.parseFloat - update affected tests to match hardened contracts

- stop deriving adapter path from request path and use adapter_id-based canonical path - remove redundant FastAPI response_model arguments matching return annotations - switch Query parameters to Annotated typing in list_jobs
