+# Preflight Checklist (Before Implementation)
+
+Use this checklist before starting Stage 20 development work.
+
+## Tools & Versions
+- [x] Circom v2.2.3+ installed (`circom --version`)
+- [x] snarkjs installed globally (`snarkjs --help`)
+- [x] Node.js + npm aligned with repo version (`node -v`, `npm -v`)
+- [x] Vitest available for JS SDK tests (`npx vitest --version`)
+- [ ] Python 3.13+ with pytest (`python --version`, `pytest --version`)
+- [ ] NVIDIA drivers + CUDA installed (`nvidia-smi`, `nvcc --version`)
+- [ ] Ollama installed and running (`ollama list`)
+
+## Environment Sanity
+- [x] `.env` files present/updated for coordinator API
+- [x] Virtualenvs active (`.venv` for Python services)
+- [x] npm/yarn install completed in `packages/js/aitbc-sdk`
+- [x] GPU available and visible via `nvidia-smi`
+- [x] Network access for model pulls (Ollama)
+
+## Baseline Health Checks
+- [ ] `npm test` in `packages/js/aitbc-sdk` passes
+- [ ] `pytest` in `apps/coordinator-api` passes
+- [ ] `pytest` in `apps/blockchain-node` passes
+- [ ] `pytest` in `apps/wallet-daemon` passes
+- [ ] `pytest` in `apps/pool-hub` passes
+- [x] Circom compile sanity: `circom apps/zk-circuits/receipt_simple.circom --r1cs -o /tmp/zkcheck`
+
+## Data & Backup
+- [ ] Backup current `.env` files (coordinator, wallet, blockchain-node)
+- [ ] Snapshot existing ZK artifacts (ptau/zkey) if any
+- [ ] Note current npm package version for JS SDK
+
+## Scope & Branching
+- [ ] Create feature branch for Stage 20 work
+- [ ] Confirm scope limited to 01–04 task files plus testing/deployment updates
+- [ ] Review success metrics in `00_nextMileston.md`
+
+## Hardware Notes
+- [ ] Target consumer GPU list ready (e.g., RTX 3060/4070/4090)
+- [ ] Test host has CUDA drivers matching target GPUs
+
+## Rollback Ready
+- [ ] Plan for reverting npm publish if needed
+- [ ] Alembic downgrade path verified (if new migrations)
+- [ ] Feature flags identified for new endpoints
+
+Mark items as checked before starting implementation to avoid mid-task blockers.
