chore: pre-release — full project lifecycle (CRUD, history, docs, tests)

Backend:
- GET /projects (list), DELETE /projects/{id}
- GET /inference/history
- project_id threaded through POST /work/infer + /work/blueprint (form-field)
- DailyWorkInput length caps (raw_text <= 4000, axes <= 200)
- Blueprint upload size cap (50 MB → 413)
- Supabase service: list_projects + delete_project + list_inference_history
- X-Request-ID middleware (echo / auto-generate + access log line)
- CORS constrained to the live Vercel deploy (no longer "*")
- inference_history payload now includes "persisted" hint to client

Frontend:
- /project list page → cards with cross-links to work/blueprint/documents/history
- /project/new rewired to POST /projects, surfaces returned project_id
- /work + /blueprint accept ?project_id= and thread it into the request
- /documents: full pick-project / pick-template / boilerplate / auto-download
- /history: read-only inference feed, filterable by project_id
- lib/api.ts: complete client for projects/crud/history/documents/templates

Tooling:
- pytest suite: schemas + Supabase mapping (7 tests, all pass)
- requirements-dev.txt: pytest + pytest-asyncio
- RELEASING.md: final-test checklist (mostly manual ~30 min)
- README.md updated to release-grade summary

-# Virtual Foreman — Backend API
-
-FastAPI service providing:
-- `/work/infer` — AI tech-stack synthesis (OpenRouter free models)
-- `/documents/render` — Belarusian act generation (docxtpl)
-- `/projects` — metadata (Supabase-backed)
-- Swagger UI: `/docs`
+# Виртуальный Прораб — Virtual Foreman
+
+> Construction tech-stack inference and document engine for
+> Belarusian building sites. AI-assisted daily reports, blueprint
+> reading, and TKP-compliant act generation.

+## Features
+
+- **Daily wizard** (`/work`) — write a one-line statement on the
+  smartphone, get a full engineering tech-stack back from the chief
+  engineer persona (DeepSeek V4 Flash → fallback chain).
+- **Blueprint upload** (`/blueprint`) — drop a PNG / JPEG / WebP / HEIC
+  / PDF. PDFs auto-rasterised server-side via `pypdfium2`, vision
+  handled by Llama-3.2-Vision (or Phi-4-multimodal fallback).
+- **Document generation** (`/documents`) — pick a project + template,
+  the Belarusian act drops as `.docx` via `docxtpl`.
+- **Projects CRUD** (`/project`, `/project/new`) — full Supabase
+  persistence (`/projects/{id}` GET / DELETE).
+- **Inference history** (`/history`) — read-only feed of the last
+  inferences (text + blueprint) per project or globally.
+- **Mobile-first** — every page is sub-md max-width and tap-friendly.

+# Release Checklist — Virtual Foreman
+
+> Pre-production state right now. The following items remain — all can
+> be completed in less than an hour.
+
+## ✅ Done
+
+- Backend (FastAPI) is live on Hugging Face Space.
+- Frontend (Next.js) is live on Vercel.
+- All major routes wired end-to-end:
+  - `GET /health`, `GET /`, `GET /supabase/health`
+  - `POST /projects`, `GET /projects`, `GET /projects/{id}`,
+    `DELETE /projects/{id}`
+  - `POST /work/infer`, `POST /work/blueprint`
+  - `GET /documents/templates`, `POST /documents/render`
+  - `GET /inference/history`
+- CORS constrained to the live Vercel deploy (`virt-foreman.vercel.app`)
+  plus subdomains and localhost.
+- X-Request-ID middleware on every response.
+- HF Space secret recipes documented in `backend/README.md`.
+- Legacy OpenRouter fields retained but ignored; primary NVIDIA
+  integrate chain (`DeepSeek V4 Flash` + fallbacks) is active.
+- Vision path uses `Llama-3.2-Vision-11B → 90B → Phi-4-multimodal`.
+- PDF render pipeline (`pypdfium2 + Pillow`) renders first page to PNG
+  before VLM call, capped at 1536 px on longest edge.
+- Stub fallbacks for inference exhaustion — UI never dead-ends.
+- Pytest suite covers schemas + Supabase column mapping (7 tests).
+- All commits authored `dirboll@gmail.com` (Vercel bot-check OK).
+
+## 🟡 Manual steps remaining (~ 30 minutes)
+
+1. **Apply the Supabase delta schema**
+   - Open https://supabase.com/dashboard/project/hjkubelrluueugdjsqyn/sql/new
+   - Paste contents of `backend/supabase/schema.sql`
+   - Click **Run** → confirm `inference_history` appears in the table
+     editor.
+
+2. **Verify secrets on the HF Space**
+   - https://huggingface.co/spaces/Dirbol/VirtForemanBackend/settings/secrets
+   - `SUPABASE_URL` ✅
+   - `SUPABASE_SECRET_KEY` (or `SUPABASE_KEY`) ✅
+   - `LLM_API_KEY` (= NVIDIA integrate API key) ✅
+   - Optional: `HF_TOKEN` for monitoring
+
+3. **Vercel one-time connect** (skipped in Termux)
+   - Vercel dashboard → "Add New Project" → "Import Git Repository"
+   - Pick `dirboll-commits/VirtForeman`
+   - Root directory: repo root (already Next.js-shaped)
+   - Env vars in Vercel project settings:
+     - `NEXT_PUBLIC_API_URL=https://dirbol-virtforemanbackend.hf.space`
+     - `NEXT_PUBLIC_APP_NAME=Virtual Foreman`
+
+4. **Health checks**
+   - `curl https://dirbol-virtforemanbackend.hf.space/health` → 200
+   - `curl https://dirbol-virtforemanbackend.hf.space/supabase/health`
+     → `{configured:true, reachable:true, rows_in_projects_sample:1}`
+   - `curl https://virt-foreman.vercel.app/` → 200, home page renders
+
+5. **End-to-end smoke** (manual, in browser)
+   - Create project → /work, /blueprint, /documents chained actions.
+   - Verify each inference shows up under /history.
+   - Verify document download opens in Word / LibreOffice.
+
+6. **Run the regression suite**
+   ```bash
+   pip install -r requirements-dev.txt
+   pytest tests/test_schemas.py tests/test_supabase_mapping.py -v
+   ```
+   Expected output: `7 passed`.
+
+7. **Production hardening (optional)**
+   - Rate-limit per IP on `/work/infer` and `/work/blueprint`.
+   - Auth layer (Supabase Auth widgets or OIDC for the frontend).
+   - Email verification before document download.
+
+## 📋 Deployment commands cheat-sheet
+
+```bash
+# Backend → HF Space
+git push hf <branch>:main
+
+# Frontend → Vercel (Vercel auto-deploys on push to origin/main)
+git push origin <branch>:refs/heads/main --force
+```
+
+Both must succeed for a clean release. Roll back via Vercel "Promote previous deployment" / HF revert.
+
+## 🔁 Logs
+
+- HF Space runtime: https://huggingface.co/spaces/Dirbol/VirtForemanBackend
+  → "Logs" tab → "Container" stream.
+- Vercel: project → "Logs" tab.
+- Local sanity: `pytest tests/ -v`.
