Production QA reported "Submit failed 413" on /generation and plain
"Upload failed" (no detail) on resource upload. Root cause is the
outer reverse-proxy nginx on the VPS — still on default
`client_max_body_size 1m` — rejecting requests before they reach
Odoo. The inner docker-nginx and Odoo limits were already raised in
earlier commits; only the VPS proxy was left unpatched.
UI side
- Add `describeApiError(err, fallback, context)` helper in
lib/api-client.ts. Maps common HTTP codes to human-readable,
actionable toast descriptions (413 → "ask ops to raise nginx
client_max_body_size", 504 → "server took too long, retry", 502
→ "Odoo is restarting", 401 → "sign in again", 4xx/5xx → server
error body + status code).
- Use it in GenerationPage submit, ResourceManager upload,
TeacherLibrary upload, CustomExamCreate save/publish. Replaces
four slightly-different ad-hoc mappings with one source of truth.
Deploy side
- Add deploy/nginx-vps.conf.example: full TLS reverse-proxy template
with the body/timeout knobs that must match Odoo's limit_request
(128 MB) and limit_time_real (900 s).
- Add docs/DEPLOY_413_504_FIX.md: step-by-step remediation guide for
the team lead covering the 3 layers that can block large bodies
(outer nginx, Cloudflare, Odoo worker) and how to verify each.
Made-with: Cursor
First-visit users now always land on the English UI regardless of
navigator.language. Arabic remains one click away via the toggle, and
the user's explicit pick is persisted to localStorage (encoach-lang)
and honoured on every subsequent load.
- src/i18n/index.ts: set lng: "en", drop navigator/htmlTag from the
detector order so an Arabic-locale browser no longer silently boots
the UI in Arabic before the user has chosen.
- src/lib/api-client.ts: mirror the same policy for the Accept-Language
header sent to the backend, so AI-generated content stays English on
first visit instead of echoing the browser locale.

Frontend
- i18n: install tailwindcss-rtl, Cairo font, RTL-aware direction in index.css.
- Language toggle: localize aria-label / menu label, persist choice, update
document dir synchronously.
- Sidebar: add `side` prop so the drawer pins to the right in RTL; wire up
AdminLmsLayout, RoleLayout (student/teacher) and AppSidebar to pass
side = i18n.dir() === 'rtl' ? 'right' : 'left'.
- AdminLmsLayout: convert every nav item from hard-coded title to titleKey,
translate group labels (incl. the collapsible Training), breadcrumbs,
user menu (Profile / Settings / Logout), help button and toggle aria
labels; replace physical mr-/right- utilities with logical me-/end-.
- AI components (AiTipBanner, AiInsightsPanel, AiAlertBanner, AiSearchBar,
AiAssistantDrawer): apply dir="auto" at the container level, localize
titles, loading / error / empty states.
- Dashboards (admin / student / teacher): wrap numeric values in <bdi>,
localize dates via ar-EG, fix flex direction for KPI and assignment cards.
- UI primitives (breadcrumb, calendar, carousel, dropdown-menu, menubar,
context-menu, pagination, sidebar): flip chevrons in RTL via a scoped
CSS rule, swap pl-/pr-/ml-/mr- for ps-/pe-/ms-/me-.
- Add logical-direction helpers and bidirectional isolation classes.
Locales
- Expand en.ts and ar.ts with full `nav`, `sidebarGroup`, `breadcrumb`,
`userMenu`, `chrome`, `ai`, and dashboard key sets; keep key parity.
API client
- `api-client.ts` reads the active language from localStorage/i18n and sends
`Accept-Language` on every request so the backend can localize AI output.
Backend (encoach_ai)
- openai_service: add _LANGUAGE_NAMES, normalize_language, language-aware
system prompt injection for every OpenAI call.
- coach_service + controllers (coach_controller, ai_controller): thread
the requested language from headers / user locale down to OpenAIService.
- ai_feedback: fix latent registry error by pointing course_id at op.course
instead of the non-existent encoach.course.
Other
- .gitignore: ignore runtime odoo logs and local caches.

Roadmap P0
- Ship /logo.svg fallback and rewire asset references (superseded later by
the project-manager PNG in a separate commit).
Roadmap P1
- Response envelope alignment ({items,total,page,size}) across services
and query hooks.
- Approval/ticket UX updates tied to the new backend rollback semantics.
Roadmap P2
- React.lazy + Vite manualChunks to split vendor-radix/charts/icons/forms
from the main bundle and cut initial JS.
- Fix the 181 tsc errors (PaginationParams class + per-service generics).
- Auto-refresh flow for JWT refresh tokens wired into api-client.ts.
Roadmap P3
- i18n: i18next + language detector, en/ar locales, RTL auto-switch,
LanguageToggle component in RoleLayout and AdminLmsLayout.
- GDPR: PrivacyCenter page for data export and right-to-erasure, backed
by gdpr.service.ts; logout via AuthContext after erasure.
- Human-in-the-loop exam review UI: admin ExamReviewQueue + ExamReviewDetail
pages, useExamReview hooks, exam-review.service.ts.
- AI quality loop: AIPromptEditor (versioning + render preview),
AIFeedbackButtons for students, AIFeedbackTriage admin page, dedicated
services, hooks, and types.
- Dark mode: ThemeProvider + ThemeToggle + chart color tokens.
- Accessibility: DialogDescription on every DialogContent; alert-dialog
and sheet updates.
- Retire dead pages: ExamPage marketing, Index, ProfilePage import.
- Playwright e2e scaffolding: playwright.config.ts + e2e/login.spec.ts
smoke tests, npm scripts test:e2e / test:e2e:install.
