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.

Addresses the QA notes on the end-to-end approval flow. Highlights:
Backend
- encoach_ai/generation_submit: create encoach.approval.request on submit so
submitted exams actually reach the approver queue (previously only the
workflow id was stored on the exam, leaving approvers with an empty inbox).
Initial exam status flips to pending_approval instead of draft.
- encoach_exam_template/approval_workflows:
* /api/approval-users filters out students (user_type='student',
op_student_id set, share=True) so the approver dropdown only lists staff.
* _ser_request enriches requests with target_name / target_status and the
current stage approver for UI badges.
* list_requests supports mine=1 / requester=1 so approvers only see queue
items awaiting their action.
* approve_request / reject_request now transition the underlying
encoach.exam.custom to published / rejected on final approval.
- encoach.exam.custom.status: add pending_approval and rejected states to
match the approval workflow transitions.
Frontend UX
- GenerationPage: rubric field shows "Auto-graded — no rubric" for Listening
and Reading (rubrics only apply to Writing / Speaking). Divider dropdowns
now carry explicit help text explaining None / Line / Space / Page Break
and where to write prompts. Selecting an official exam structure
auto-populates the required tasks/sections/parts, the delete button is
hidden for essential tasks, and submit is blocked if the user dropped
below the structure's required count.
- RubricsPage: "Add Criterion" is now a dropdown with IELTS-specific
presets (Task Achievement, Coherence & Cohesion, Fluency & Coherence, …)
keyed off the selected skill, plus a "Custom (blank row)" fallback.
- AdminCourses: added tooltips and helper copy clarifying Difficulty vs
CEFR Level in the Create Course dialog.
- CustomExamCreate: validate the whole form before Save/Publish, surface
backend error messages (413/504/401) instead of a generic toast, read the
exam id from the correct response field, and avoid marking Publish as
failed when only the optional Save-as-Template step errors.
- ResourceManager / TeacherLibrary: upload toast now shows a concrete
reason (HTTP 413 / 504 / 401) instead of a generic "Upload failed".
Config (504 / 413 / resource upload fixes)
- odoo.conf + odoo-docker.conf: raise limit_time_cpu to 600s,
limit_time_real to 900s, limit_request to 128 MB, and memory caps so
/api/exam/generation/submit and multipart resource uploads stop hitting
504 / 413 during QA.
- frontend/Dockerfile (nginx): add client_max_body_size 128m, bump
proxy_read_timeout / proxy_send_timeout to 900s, and disable request
buffering so large AI/resource payloads stream through the proxy.

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.
