docs(readme): rewrite for V2.0.0 — uv, src/ layout, stations, docs index

Brings the entry-point README in line with the V2.0.0 restructure: - Replace all server/ + client/ paths with src/backend/ + src/frontend/flask_app/. - Replace pip install -r requirements.txt with the uv workflow (uv sync --extra server --extra client --extra dev). - Manual setup section uses uv run uvicorn / uv run flask / uv run alembic / uv run pybabel, all driven from the project root. - Document the V2.0.0 additions: STATION_CODE per-tablet, /admin/ stations GUI, gunicorn 5x4 + uvicorn 4 worker scaling, X-Forwarded -For-aware rate limiting (RATE_LIMIT_GENERAL default 300). - Add tooling section (uv, pyproject.toml, uv.lock, .python-version, pytest stack). - Documentation section now points at the new docs/ index plus the STATO_PROGETTO + ROADMAP architecture pair as the canonical "what is done / what is next" references. - Variabili d'Ambiente: add STATION_CODE, RATE_LIMIT_LOGIN, RATE_LIMIT_GENERAL.

+
+## Strategia: due milestone
+
+| Milestone | Scope | Obiettivo |
+|---|---|---|
+| **M1 — Demo cliente** | Fasi 1-5 + deploy "demo" | Sistema testabile end-to-end col cliente per raccogliere feedback |
+| **M2 — Produzione** | Fasi 6-7 + correzioni post-feedback + GAIA live | Rollout su tablet/PC reali |
+
+## Stato Fasi (M1)
+
+| Fase | Scope | Stato | Branch / Commit |
+|---|---|---|---|
+| **1** | Stazioni + identità per-tablet | ✅ **COMPLETATA** | `V2.0.0` (merge `ea8e468` da `feature/rev04-phase1-stations`) |
+| 2 | Ruolo Capoturno (Supervisor) + override token breve | ⏳ Da iniziare | — |
+| 3 | Editor ricetta a blocchi (preparation + measurement) | ⏳ Da iniziare | — |
+| 4 | Workflow operatore (retry/timer/autologout/avvio produzione) | ⏳ Da iniziare | — |
+| 5 (M1) | `ImportOnlyGaiaClient` + UI import dati cliente reali | ⏳ Da iniziare | — |
+| Deploy M1 | VPS demo (compose + Traefik + LE, no registry) | ⏳ Da iniziare | — |
+
+## Stato Fasi (M2)
+
+| Fase | Scope | Stato |
+|---|---|---|
+| 5 (M2) | GAIA reale (protocollo TBD, polling, comandi produzione) | ⏳ Bloccata da decisioni cliente (D-0.1, D-0.2) |
+| 6 | Deploy B industriale (registry privato + Watchtower + STATION_ID per-tablet + CI release) | ⏳ Pianificata |
+| 7 | Hardening, security review, E2E sito pilota, docs aggiornati, i18n delta | ⏳ Pianificata |
+
+## Decisioni aperte (bloccanti per M2 / future fasi)
+
+Da: master plan §0 "Precondizioni e Decisioni Aperte". Da risolvere col cliente prima della Fase 5/6.
+
+| ID | Decisione | Stato | Bloccante per |
+|---|---|---|---|
+| D-0.1 | Protocollo integrazione GAIA (REST / DB shared / OPC-UA / file) | **Aperta** | Fase 5 reale (M2) |
+| D-0.2 | Credenziali e rete GAIA (VPN / firewall / whitelist IP) | **Aperta** | Fase 5 reale (M2) |
+| D-0.3 | Target hardware "tablet" (Windows / Linux industriale / Android) | **Aperta** | Fase 6 (deploy B) |
+| D-0.4 | Cicalino/luce avviso (audio HTML5 / hardware USB / entrambi) | **Rimandata a M2** | Fase 4 finale |
+| D-0.5 | Parametri runtime modificabili vs versione immutabile | **Aperta** (raccomandato B: separare volatili) | Fase 3 |
+| D-0.6 | Auth capoturno durante override (modale / PIN / RFID) | **Aperta** | Fase 2 |
+| D-0.7 | Timeout auto-logout | **Risolta** | — |
+| D-0.8 | Naming ruolo capoturno | **Proposta:** `Supervisor` | Fase 2 |
+| D-0.9 | Tag versione immagine docker | **Proposta:** SemVer + `latest` | Fase 6 |
+| D-0.10 | Registry esposto su Internet o solo VPN | **Proposta:** solo VPN cliente | Fase 6 |
+
+## Tech debt da chiudere
+
+| Item | Priorità | Note |
+|---|---|---|
+| 3 test backend pre-esistenti rotti (`test_recipes`, `test_tasks`) | Media | Investigare prima di Fase 3 (toccano recipe + task router). |
+| 1 test client pre-esistente rotto (`test_save_measurement_proxy`) | Bassa | Probabilmente CSRF/payload. Risolvere con Fase 4. |
+| `.env` rename a convenzione spec (SERVICE_NAME, SERVICE_DOMAIN, API_KEY) | Bassa | Rinviato (impatto deploy). |
+| Header `X-API-Key` rename a `X-Api-Key` | Bassa | Vedere se M2 lo richiede. |
+| Envelope risposta `{success,data,error}` | Bassa | Eventuale API v2 in M2. |
+| `Dockerfile.frontend`: `pybabel compile` via `uv run` non testato in build reale | Alta | Verificare al primo `docker compose build`. |
+
+## Open per scelta utente prima della prossima sessione
+
+1. **Quale fase iniziare adesso?** Opzioni: Fase 2 (Supervisor — sblocca workflow), Fase 3 (block editor — independente), Fase 5 (import GAIA dati reali — sblocca demo).
+2. **Revisione decisioni aperte col cliente** — D-0.1 / D-0.2 / D-0.3 / D-0.6 prima di pianificare Fase 5 e 6.
+3. **Smoke test Docker** della nuova struttura V2.0.0 (`docker compose -f docker-compose.dev.yml up --build`) per validare i Dockerfile riscritti.
+4. **Test di carico** (k6/locust) a 20 VU su `/measure/save-measurement` per validare la scalatura worker (capacità annunciata: 20-30 tablet contemporanei).
+
+## Stima tempi residui M1 (post-Fase 1)
+
+| Task | Stima full-time |
+|---|---|
+| Fase 2 — Supervisor + override | 1 settimana |
+| Fase 3 — Block editor | 1.5 settimane |
+| Fase 4 — Workflow operatore | 2 settimane |
+| Fase 5 (M1) — Import-only GAIA | 1 settimana |
+| Deploy M1 demo | 0.5 settimane |
+| **Totale M1 residuo** | **~6 settimane** |
+
+## Stima tempi M2 (dopo feedback)
+
+| Task | Stima |
+|---|---|
+| Aggiustamenti post-feedback | variabile (1-2 sett.) |
+| Fase 5 reale GAIA | 1-2 settimane |
+| Fase 6 deploy B | 1 settimana |
+| Fase 7 hardening | 1-2 settimane |
+| **Totale M2** | **~4-7 settimane** |

+# Stato Progetto TieMeasureFlow — V2.0.0
+
+> Snapshot al 2026-04-25. Aggiornare ad ogni milestone.
+
+## Versione corrente
+
+**V2.0.0** (in sviluppo, branch `V2.0.0` come default su `git.tielogic.xyz`).
+
+Versione precedente di produzione: `V1.0.7`.
+
+## Sintesi esecutiva
+
+Il sistema base (V1.0.7) è completo e collaudato: ricette, task, misurazioni, SPC, report PDF, gestione utenti, dashboard metrologist. La V2.0.0 in corso aggiunge il primo blocco della migrazione **rev04** (stazioni per-tablet) e ristruttura l'intero monorepo secondo lo standard `python-project-spec-design.md` (uv + `src/backend/` + `src/frontend/flask_app/`).
+
+## Cosa funziona oggi (V2.0.0 — branch corrente)
+
+### Funzionalità ereditate da V1.0.7
+- Autenticazione username/password + API key per-utente, ruoli combinabili (Maker, MeasurementTec, Metrologist) + flag `is_admin`.
+- Recipe versioning copy-on-write: una nuova versione si crea solo se la corrente ha già measurements; altrimenti update in-place.
+- Editor ricette (Maker) con annotation editor Fabric.js (~1200 LOC, collaudato su tablet).
+- Workflow operatore tablet: select_recipe → task_list → task_execute → task_complete, con barcode scanner e numpad touch (input USB calibro con burst detection).
+- Calcolo pass/fail con limiti UTL/UWL/LWL/LTL.
+- Dashboard SPC: capability (Cp/Cpk/Pp/Ppk), control chart (UCL/LCL = mean ± 3σ), istogramma con curva normale, calcoli puro stdlib (no numpy).
+- Report PDF (WeasyPrint + Kaleido SVG).
+- Setup page protetta da `SETUP_PASSWORD` per inizializzazione DB e seed.
+- i18n IT/EN (Flask-Babel + Alpine.js JSON).
+- Tema light/dark via `Alpine.store('theme')` + localStorage.
+
+### Aggiunte V2.0.0 (rev04 Fase 1 — Stazioni per-tablet)
+- Tabelle `stations` + `station_recipe_assignments` (Alembic migration `002_add_stations.py`).
+- Modelli ORM: `Station`, `StationRecipeAssignment` con vincolo unique `(station_id, recipe_id)`.
+- Schemas Pydantic: `StationCreate/Update/Response`, `StationRecipeAssignmentCreate/Response`, `RecipeSummary`.
+- Service `station_service` (CRUD + assegnazioni + cascade delete).
+- Router `/api/stations` con CRUD admin + endpoint operatore `GET /api/stations/by-code/{code}/recipes`.
+- Seed automatico `ST-DEFAULT` con tutte le ricette esistenti (idempotente).
+- Variabile env client `STATION_CODE` letta da `Config`, helper `APIClient.get_station_recipes()`.
+- Filtro `select_recipe`: il client mostra solo le ricette assegnate alla propria stazione, errore se `STATION_CODE` non configurato.
+- **GUI admin completa** in `/admin/stations`: tabella con search, modal create/edit, modal gestione assegnazioni ricette, conferma eliminazione, link in navbar (desktop + mobile).
+- 47 nuovi test (32 server + 15 client) tutti pass.
+
+### Aggiunte V2.0.0 (performance + multi-utente)
+- Gunicorn 5 workers × 4 thread (gthread) — capacità ~20 richieste concorrenti Flask, regge 20+ tablet.
+- Uvicorn 4 workers + `--proxy-headers --forwarded-allow-ips='*'`.
+- Rate limit middleware: identificazione IP reale via `X-Forwarded-For` → `X-Real-IP` → `request.client.host`.
+- Rate limit general 100 → 300 req/min/IP (per-tablet ora, non più condiviso).
+- Flask `ProxyFix(x_for=1, x_proto=1, x_host=1)` per IP reale dietro Nginx.
+- `APIClient` propaga `X-Forwarded-For` + `X-Real-IP` (sia JSON che multipart).
+- 12 test aggiuntivi (7 server + 5 client).
+
+### Aggiunte V2.0.0 (struttura monorepo)
+- `pyproject.toml` unico con extra `server`/`client`/`dev`. Niente più `requirements.txt`.
+- `uv.lock` (77 pacchetti) + `.python-version` (3.11) committati per build riproducibili.
+- Layout `src/backend/` + `src/frontend/flask_app/` (vedi sotto).
+- `Dockerfile` (root) + `Dockerfile.frontend` riscritti con `uv sync --frozen --no-dev --extra server|client`.
+- `docker-compose.{dev,}.yml` con build context `.`.
+- Alembic env.py aggiunge project root a `sys.path`; `script_location = %(here)s` resta valido.
+- `.dockerignore` aggiornato.

+- **Frontend:** Flask + Jinja2 + Alpine.js + TailwindCSS + Fabric.js 5.3.1 + html5-qrcode + Plotly.js + Flask-Babel.
+- **Deploy:** Docker Compose. Dev = Nginx; Prod = Traefik + Let's Encrypt SSL.
+- **Tooling:** uv (package mgmt), pytest + pytest-asyncio + httpx + aiosqlite (test).
+
+## Decisioni architetturali rilevanti
+
+| Decisione | Stato | Note |
+|---|---|---|
+| Frontend Flask invece di React (deroga vs spec §8) | **Confermata** | Tablet UX server-side, USB calipers/barcode, Fabric.js editor, i18n Babel collaudato. Vedi conversazione 2026-04-25. |
+| NATS messaging (spec §7) | **Skippato** | Monorepo single-host, no microservizi. Nessuno stub `nats_client/` creato. |
+| Envelope risposta `{success,data,error}` (spec §6) | **Rimandato** | Costo 4-5gg refactor + rotture client. Eventuale v2 API in M2. |
+| Header `X-API-Key` vs spec `X-Api-Key` | **Mantenuto attuale** | Rinominare costa 50+ punti di codice + breaking per deploy. Rivedere in M2. |
+| Variabili `.env` (DB_HOST, SERVER_PORT, ...) | **Mantenute attuali** | Rename a SERVICE_NAME/SERVICE_DOMAIN/API_KEY rinviato (impatta deploy esistenti). |

Author	SHA1	Message	Date
Adriano	563b7789f4	docs(readme): rewrite for V2.0.0 — uv, src/ layout, stations, docs index Brings the entry-point README in line with the V2.0.0 restructure: - Replace all server/ + client/ paths with src/backend/ + src/frontend/flask_app/. - Replace pip install -r requirements.txt with the uv workflow (uv sync --extra server --extra client --extra dev). - Manual setup section uses uv run uvicorn / uv run flask / uv run alembic / uv run pybabel, all driven from the project root. - Document the V2.0.0 additions: STATION_CODE per-tablet, /admin/ stations GUI, gunicorn 5x4 + uvicorn 4 worker scaling, X-Forwarded -For-aware rate limiting (RATE_LIMIT_GENERAL default 300). - Add tooling section (uv, pyproject.toml, uv.lock, .python-version, pytest stack). - Documentation section now points at the new docs/ index plus the STATO_PROGETTO + ROADMAP architecture pair as the canonical "what is done / what is next" references. - Variabili d'Ambiente: add STATION_CODE, RATE_LIMIT_LOGIN, RATE_LIMIT_GENERAL. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>	2026-04-25 12:48:51 +02:00
Adriano	e4b29c0b2d	chore(docs): consolidate documentation, drop dead files Cleanup - Remove src/backend/Dockerfile.legacy and src/frontend/flask_app/Dockerfile.legacy (history is in git, build uses the new uv-based root Dockerfile / Dockerfile.frontend). - Remove src/frontend/flask_app/verify_i18n.py (had hardcoded paths pointing at the old client/ tree). Group docs/ - New docs/README.md indexes everything in one place. - New docs/architecture/STATO_PROGETTO.md: snapshot of what works in V2.0.0 (inherited V1.0.7 features, rev04 Phase 1 stations, worker scaling, src/ restructure, test status, stack, decisions). - New docs/architecture/ROADMAP.md: what's next — Phases 2-7 of the rev04 migration with status, open client decisions (D-0.1 through D-0.10), tech debt and time estimates for M1 / M2. - Move PIANO_IMPLEMENTAZIONE.md (90KB V1.0.0 plan) to docs/archive/2026-02-06-piano-implementazione-v1.md (historical). - Move Schema sviluppo SW TieFlow_rev04-2026.docx to docs/specs/ with ISO date filename so the customer spec is now tracked. - Move src/frontend/flask_app/I18N_SETUP.md to docs/I18N_SETUP.md and rewrite paths to the new src/frontend/flask_app/ tree. .dockerignore: simplified now that legacy Dockerfiles are gone; docs/ stays excluded from the build context.

Adriano	1a0431366f	chore(v2): restructure monorepo to src/ layout with uv Aligns the repo with the python-project-spec-design.md template chosen for V2.0.0. Big move, no logic changes. The 3 pre-existing test failures (test_recipes::test_update_recipe, test_recipes:: test_recipe_versioning, test_tasks::test_reorder_tasks, plus the client test_save_measurement_proxy) survive unchanged. Layout changes - server/ -> src/backend/ - server/middleware/ -> src/backend/api/middleware/ - server/routers/ -> src/backend/api/routers/ - server/models/ -> src/backend/models/orm/ - server/schemas/ -> src/backend/models/api/ - server/uploads/ -> uploads/ (project root, mounted volume) - server/tests/ -> src/backend/tests/ - client/ -> src/frontend/flask_app/ (Flask kept; React deroga is documented in CLAUDE.md, justified by tablet UX, USB caliper/barcode workflow and Fabric.js integration) Tooling - pyproject.toml: monorepo with [project] core deps and optional-dependencies server / client / dev. Replaces both server/requirements.txt and client/requirements.txt. - uv.lock + .python-version (3.11) committed for reproducible builds. - Dockerfile (root, backend) and Dockerfile.frontend rewritten to use uv sync --frozen --no-dev --extra server\|client; legacy Dockerfiles preserved as Dockerfile.legacy for reference but excluded from build context via .dockerignore. - docker-compose.dev.yml + docker-compose.yml: build context now ".", dockerfile pointing to the root files. Code adjustments forced by the move - Every "from config\|database\|models\|schemas\|services\|routers\|middleware import ..." rewritten to its src.backend.* equivalent (50+ files including indented inline imports inside test bodies). - src/backend/migrations/env.py: insert project root into sys.path so alembic can resolve src.backend.* imports regardless of cwd. - src/backend/config.py: env_file ../../.env (was ../.env), upload_path resolves project root via parents[2]. - src/backend/tests/conftest.py + tests: import ... from src.backend.* instead of bare names; old per-directory pytest.ini files removed in favor of root pyproject.toml [tool.pytest.ini_options]. - .gitignore: uploads/ at root, src/frontend/flask_app/static/css/ tailwind.css path; .dockerignore tightened. - CLAUDE.md: rewrote sections "Layout del repository", "Comandi di Sviluppo", "Database & Migrations", "Test", "i18n", and all path references throughout the architecture sections. Verified - uv lock resolves 77 packages; uv sync --extra server --extra client --extra dev installs cleanly. - uv run pytest: 171 passed, 4 pre-existing failures. - uv run alembic -c src/backend/migrations/alembic.ini check loads config and metadata (errors only on the absent local MySQL).

Adriano	86df67f2e5	perf: scale workers + per-tablet rate limiting for 20 concurrent users The default 2-worker gunicorn could only serve 2 concurrent tablet requests, queueing the rest, and the rate limiter saw every tablet as the same Nginx container IP, so 20 users would have collectively burned through the 100 req/min general bucket. - gunicorn: 5 workers x 4 gthread, --forwarded-allow-ips=, access log - uvicorn: 4 workers, --proxy-headers, --forwarded-allow-ips= - RateLimitMiddleware: resolve real client IP from X-Forwarded-For -> X-Real-IP -> request.client.host - Bump rate_limit_general 100 -> 300 req/min/IP (per tablet now) - Flask: ProxyFix(x_for=1, x_proto=1, x_host=1) so request.remote_addr is the tablet IP, not the Nginx IP - APIClient: forward X-Forwarded-For + X-Real-IP to FastAPI for both JSON and multipart/files calls; safe no-op outside request context - 12 new tests (7 server + 5 client) covering header precedence, forwarding behavior and ProxyFix install Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>	2026-04-25 12:07:43 +02:00
