test(s16): regression suite 35 flows + visual 60 snapshots + nightly + CI badges

Sprint 16 — постоянный regression-контур: flows + visual + nightly + CI workflow + README badges. Ключевые цифры: - 35 flow-тестов: 35/35 ✓ за ~30 секунд (workers=2 локально). - 60 visual snapshot'ов (15 страниц × 2 темы × 2 viewport'a): 60/60 ✓ за ~4 минуты с retries=1. - Полный регресс прогон: ~5 минут (цель была < 15). Что сделано: 1. tests/regression/ — Playwright + factories + 8 spec-файлов. OrgFactory builder создаёт org через API за O(N) HTTP вызовов (signup → token → refs → products → counterparties → posted supplies). Каждый flow независим, использует свой fresh-org. 2. tests/regression/visual/ — 15 страниц × 2 темы × 2 viewport'a. Маски на динамический контент (артикулы с Date.now, KPI'ы, delta-стрелки) чтобы 0.2% threshold не флакал. snapshotPathTemplate c {projectName} — desktop+mobile не затирают друг друга. 3. tests/regression/factories/OrgFactory.ts — builder с .withProducts .withCounterparties .withSupplies. Retry signup'a на 429. 4. .forgejo/workflows/regression.yml — on workflow_run после Docker API/Web; cache на pnpm-store + Playwright-browsers; артефакты при failure; Telegram-уведомление в обоих случаях. 5. ~/nightly-verify.sh + cron `0 4 * * *`: health → redeploy если нужно → smoke flows; в воскресенье полный flows+visual. Логи с ротацией 14 дней. Telegram на провал (~/.fm-watchdog/telegram-*). 6. scripts/generate-badges.sh — coverage из cobertura.xml в SVG через shields.io (offline fallback). 4 CI-status badge + coverage badge в README; CI step «Update coverage badge» авто-коммитит обновлённый SVG на push в main. Локальное число flake'ов: 1/60 visual на retry=1 (product-new light) — случайная гонка маски, retry'ит и проходит. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

+# Sprint 16 — E2E regression suite + visual regression + nightly verify
+
+Цель: построить «постоянный» regression-контур, чтобы регресс ловился
+сам — не «вспомнили посмотреть». 35 user-flow specs + 60 visual
+snapshot'ов + автоматический nightly + CI на каждый push в main.
+
+Старт: 2026-06-07 (после Sprint 15). Исполнитель: Claude Opus 4.7.
+
+## Принципы
+
+- Каждый flow — независимый, использует фабрику для подготовки данных
+  через API (не через UI-клики).
+- Visual baseline — fresh stage post-deploy. Diff threshold 0.2% +
+  маски на динамический контент (timestamps в артикулах, KPI).
+- Полный прогон < 15 минут (Playwright workers + retry=1 на CI).
+- НЕ трогать: `global.json`, prod admin.food-market.kz, POS WPF.
+
+## Чек-лист
+
+- [x] **1. Regression suite** — `tests/regression/flows/` — **35 ключевых
+  flow-тестов** в 8 spec-файлах (auth, catalog, documents post/unpost,
+  reports, multi-tenant isolation, i18n+permissions+2FA+audit,
+  realtime+misc). Прогон параллелен (workers=2 локально, 4 на CI).
+  Отчёт `reports/playwright-html/` + JSON `reports/results.json`.
+- [x] **2. Visual regression** — `tests/regression/visual/` —
+  **60 snapshot'ов** (15 страниц × 2 темы × 2 viewport'a:
+  desktop 1280×800 + mobile Pixel 5 375×667). Threshold 0.002 (0.2%) +
+  маски на артикулы/KPI/delta'ы для устойчивости к timestamp-дрейфу.
+- [x] **3. Test data factories** — `tests/regression/factories/` —
+  `OrgFactory.for(slug).withProducts(N).withCounterparties(M).withSupplies(K).build()`
+  собирает org через API за O(N) HTTP-вызовов (signup → token → refs →
+  products → counterparties → posted supplies). Используется в каждом
+  flow-тесте вместо signup-form.
+- [x] **4. Forgejo workflow `.forgejo/workflows/regression.yml`** —
+  on `workflow_run` после Docker API/Web, wait-for-ready → install
+  pnpm + chromium → flows + visual → артефакты + Telegram на падение.
+  Cache на pnpm-store + Playwright-browsers — повторный прогон ~3 мин.
+- [x] **5. Nightly cron** — `~/nightly-verify.sh` + cron `0 4 * * *`:
+  health-check → если падает, redeploy-stage → smoke flows
+  (`@smoke` tag) → в воскресенье ещё полный flows + visual.
+  Лог `~/.fm-watchdog/nightly-YYYYMMDD.log`, ротация >14 дней.
+  Telegram-уведомление если упало (читает токен из
+  `~/.fm-watchdog/telegram-token`).
+- [x] **6. README badges** — добавлены 4 CI-status badge (CI, Docker API,
+  Stage verify, Regression — берутся с Forgejo `actions/workflows/*.svg`)
+  + coverage badge (`badges/coverage.svg`, генерируется
+  `scripts/generate-badges.sh` из cobertura.xml, авто-коммит из CI step
+  «Update coverage badge»).
+
+## Замеры
+
+### Regression suite stats
+
+| Файл | Tests | Время (workers=2) |
+|---|---|---|
+| `flows/01-factory-smoke.spec.ts` | 1 | 5s |
+| `flows/02-auth.spec.ts` | 4 (login/signup/refresh/wrong-pw) | 4s |
+| `flows/03-catalog.spec.ts` | 5 (CRUD product/counterparty/store/price-type) | 6s |
+| `flows/04-documents.spec.ts` | 8 (supply/enter/retail-sale/loss/transfer/demand/supplier-return post+unpost) | 12s |
+| `flows/05-reports.spec.ts` | 4 (sales/stock/profit/abc с проверкой чисел) | 6s |
+| `flows/06-multi-tenant.spec.ts` | 3 (list-isolation, get-by-id-isolation, sales-isolation) | 4s |
+| `flows/07-i18n-permissions.spec.ts` | 5 (locale switch, 2FA enroll, audit log, anon→401) | 5s |
+| `flows/08-realtime-misc.spec.ts` | 5 (dashboard render, search, /health/ready) | 6s |
+| **Total** | **35** | **~30 секунд** ✓ |
+
+| Visual project | Snapshot count | Время |
+|---|---|---|
+| `desktop-chromium` 1280×800 | 30 (15 страниц × 2 темы) | 2m 10s |
+| `mobile-chromium` 375×667 (Pixel 5) | 30 | 2m 5s |
+| **Total** | **60** | **~4 минуты** |
+
+**Общий прогон**: ~30 сек (flows) + ~4 мин (visual) = **< 5 минут** end-to-end —
+существенно ниже 15-минутного целевого порога.
+
+### Coverage badge
+
+- `scripts/generate-badges.sh` берёт cobertura.xml, считает покрытие
+  по Application + Domain (combined), генерирует SVG через shields.io
+  (offline fallback inline).
+- Текущее значение: **80%** (от Sprint 15 baseline).
+- Цвет шкалы: <50% red, 50-69% yellow, 70-84% green, ≥85% brightgreen.
+- CI step «Update coverage badge» (`.forgejo/workflows/ci.yml`) на
+  каждый push в main:
+  1. `dotnet test --collect:"XPlat Code Coverage"`,
+  2. `bash scripts/generate-badges.sh`,
+  3. diff → commit `chore(badges): update coverage [skip ci]` → push.
+
+### Nightly cron
+
+- Скрипт `~/nightly-verify.sh` (217 строк bash).
+- Crontab: `0 4 * * * /home/nns/nightly-verify.sh`.
+- Последовательность:
+  1. `curl /health/ready` — если не Healthy → `~/deploy-stage.sh` → повторная проверка → если опять упала → Telegram + exit.
+  2. `pnpm install` (если node_modules нет) + `playwright test flows/ --grep @smoke`.
+  3. Если воскресенье — полный прогон `flows/ visual/`.
+  4. Telegram-уведомление при провале (`~/.fm-watchdog/telegram-{token,chat}`).
+- Логи: `~/.fm-watchdog/nightly-YYYYMMDD.log`, `find -mtime +14 -delete`
+  чистит каждый запуск.
+
+## Журнал
+
+### 2026-06-07 старт
+Sprint 15 закрыт (7/7 ✓). Поехали по regression-чек-листу.
+
+### 2026-06-07 п.3 (factory) — фундамент
+`tests/regression/factories/OrgFactory.ts` + `api-client.ts` + `types.ts`.
+Builder-pattern: `OrgFactory.for(slug).withProducts(N)…build()`.
+Реквест-клиент на `fetch` (Node 20+), retry на 429 со сдвинутым backoff
+(под Sprint 13 IP-лимит signup'a).
+
+### 2026-06-07 п.1 (35 flows)
+8 spec-файлов с тегами `@smoke` на ключевых flows для быстрого прогона.
+API-driven где возможно (быстрее UI-кликов), Playwright UI только там
+где нужно (form-login, dashboard render, локаль switch).
+
+Несколько мелких фиксов по ходу:
+- Profit/ABC report возвращают непосредственно List, не PagedResult — `rowsOf` helper.
+- Multi-tenant isolation проверять по `id`, не `name` (одинаковые
+  product-names в разных org'ах — норма).
+- Login редиректит на «/» (OnboardingPage) на свежей org, не /dashboard.
+- Loss-endpoint enum'у reason требует int, не строку.
+
+### 2026-06-07 п.2 (visual 60)
+2 spec'a (auth-pages + authenticated-pages). Baseline на свежий
+deploy. Маски на динамический контент:
+- `table td:nth-child(2)` (артикул с Date.now()),
+- `[data-kpi]` (зависит от текущей даты),
+- `[data-delta]` (стрелка от prev period).
+
+snapshotPathTemplate включает `{projectName}` чтобы desktop+mobile
+snapshot'ы не затирали друг друга.
+
+### 2026-06-07 п.4 (forgejo workflow)
+`.forgejo/workflows/regression.yml` — `on workflow_run` после
+Docker API/Web. Cache на pnpm-store + Playwright-browsers. Артефакты
+upload при failure, Telegram-уведомление в обоих случаях.
+
+### 2026-06-07 п.5 (nightly cron)
+`~/nightly-verify.sh` + crontab entry. Health → redeploy → smoke →
+weekly full + Telegram. Логи с ротацией.
+
+### 2026-06-07 п.6 (badges)
+`scripts/generate-badges.sh` — coverage из cobertura.xml → SVG через
+shields.io с offline-fallback. 4 CI-status badge + coverage badge
+добавлены в README. CI-step авто-обновляет coverage badge на push в main.
+
+## Итог
+
+Все 6 пунктов ✓. Локальные числа:
+- **35 flow-тестов**: 35/35 ✓ при workers=2 (~30 сек).
+- **60 visual snapshot'ов**: 60/60 ✓ при CI=1 (retries=1) (~4 мин).
+- **Полный прогон**: ~5 минут — **3× ниже** 15-минутного целевого порога.
+
+Контур регрессии работает:
+- На каждый push в main: Forgejo `Docker API`/`Docker Web` → `regression.yml`
+  → 35 flows + 60 visual + Telegram.
+- Каждую ночь: nightly cron → health → smoke (или полный в воскресенье)
+  + Telegram при провале.
+- Coverage и CI-status badges в README обновляются автоматически.
+
+Следующее расширение (не в этом sprint'е):
+- Перенести visual baseline'ы в LFS если они станут большими (сейчас 60
+  PNG ~10 МБ, в репе ок).
+- Добавить performance regression (k6 в CI nightly), сейчас k6 запускается
+  только вручную.
+- Заглушить flake в `product-new light` через определённый wait или
+  более широкую маску.

+ *  - Organization + Admin user (signup),
+ *  - access_token,
+ *  - N товаров,
+ *  - M контрагентов (опционально),
+ *  - K документов (опционально).
+ *
+ * Возвращает один объект OrgSession + опционально кеш ссылок (refIds,
+ * products, counterparties, supplies). Используется в каждом
+ * regression-flow вместо повторного signup + form-fill.
+ *
+ * Дизайн: builder-pattern с цепочкой `.withProducts(N).withSupplies(M).build()`,
+ * чтобы тест запросил ровно тот фикстур-набор который нужен. Без
+ * "монстро-фабрики" которая всегда делает всё.
