backend/api/middleware/context.go (new): - Introduces an unexported ctxKey type and three constants (ctxKeyUserAddress, ctxKeyUserTrack, ctxKeyAuthenticated) that replace the bare string keys 'user_address', 'user_track', and 'authenticated'. Bare strings trigger go vet's SA1029 and collide with keys from any other package that happens to share the name. - Helpers: ContextWithAuth, UserAddress, UserTrack, IsAuthenticated. - Sentinel: ErrMissingAuthorization replaces the misuse of http.ErrMissingFile as an auth-missing signal. (http.ErrMissingFile belongs to multipart form parsing and was semantically wrong.) backend/api/middleware/auth.go: - RequireAuth, OptionalAuth, RequireTrack now all read/write via the helpers; no more string literals for context keys in this file. - extractAuth returns ErrMissingAuthorization instead of http.ErrMissingFile. - Dropped now-unused 'context' import. backend/api/track4/operator_scripts.go, backend/api/track4/endpoints.go, backend/api/rest/features.go: - Read user address / track via middleware.UserAddress() and middleware.UserTrack() instead of a raw context lookup with a bare string key. - Import 'github.com/explorer/backend/api/middleware'. backend/api/track4/operator_scripts_test.go: - Four test fixtures updated to seed the request context through middleware.ContextWithAuth (track 4, authenticated) instead of context.WithValue with a bare 'user_address' string. This is the load-bearing change that proves typed keys are required: a bare string key no longer wakes up the middleware helpers. backend/api/middleware/context_test.go (new): - Round-trip test for ContextWithAuth + UserAddress + UserTrack + IsAuthenticated. - Defaults: UserTrack=1, UserAddress="", IsAuthenticated=false on a bare context. - TestContextKeyIsolation: an outside caller that inserts 'user_address' as a bare string key must NOT be visible to UserAddress; proves the type discipline. - ErrMissingAuthorization sentinel smoke test. Verification: - go build ./... clean. - go vet ./... clean (removes SA1029 on the old bare keys). - go test ./api/middleware/... ./api/track4/... ./api/rest/... PASS. Advances completion criterion 3 (Auth correctness).
SolaceScan Explorer - Tiered Architecture
🚀 Quick Start - Complete Deployment
Execute this single command to complete all deployment steps:
cd ~/projects/proxmox/explorer-monorepo
bash EXECUTE_DEPLOYMENT.sh
What This Does
- ✅ Tests database connection
- ✅ Runs migration (if needed)
- ✅ Stops existing server
- ✅ Starts server with database
- ✅ Tests all endpoints
- ✅ Provides status summary
Manual Execution
If the script doesn't work, see START_HERE.md for step-by-step manual commands.
Frontend
- Production (canonical target): the current Next.js standalone frontend in
frontend/src/, built fromfrontend/withnpm run buildand deployed to VMID 5000 as a Node service behind nginx. - Canonical deploy script:
./scripts/deploy-next-frontend-to-vmid5000.sh - Canonical nginx wiring: keep
/api,/api/config/*,/explorer-api/*,/token-aggregation/api/v1/*,/snap/, and/health; proxy/and/_next/to the frontend service usingdeployment/common/nginx-next-frontend-proxy.conf. - Legacy fallback only: the static SPA (
frontend/public/index.html+explorer-spa.js) remains in-repo for compatibility/reference, but it is not a supported primary deployment target. - Architecture command center:
frontend/public/chain138-command-center.html— tabbed Mermaid topology (Chain 138 hub, network, stack, flows, cross-chain, cW Mainnet, off-chain, integrations). Linked from the SPA More → Explore → Visual Command Center. - Legacy static deploy scripts:
./scripts/deploy-frontend-to-vmid5000.shand./scripts/deploy.shnow fail fast with a deprecation message and point to the canonical Next.js deploy path. - Frontend review & tasks: frontend/FRONTEND_REVIEW.md, frontend/FRONTEND_TASKS_AND_REVIEW.md

Reusable libs (extraction)
Reusable components live under backend/libs/ and frontend/libs/ and may be split into separate repos and linked via git submodules. Clone with submodules:
git clone --recurse-submodules <repo-url>
# or after clone:
git submodule update --init --recursive
See docs/REUSABLE_COMPONENTS_EXTRACTION_PLAN.md for the full plan.
Testing
- All unit/lint:
make test— backendgo test ./...and frontendnpm test(lint + type-check). - Backend:
cd backend && go test ./...— API tests run without a real DB; health returns 200 or 503, DB-dependent endpoints return 503 when DB is nil. - Frontend:
cd frontend && npm run buildornpm test— Next.js build (includes lint) or lint + type-check only. - E2E:
make test-e2eornpm run e2efrom repo root — Playwright tests against https://blockscout.defi-oracle.io by default; useEXPLORER_URL=http://localhost:3000for local.
Status
✅ All implementation complete
✅ All scripts ready
✅ All documentation complete
✅ Frontend: C1–C4, M1–M4, H4, H5, L2, L4 done; H1/H2/H3 (escapeHtml/safe href) in place; optional L1, L3 remain
✅ CI: backend + frontend tests; lint job runs go vet, npm run lint, npm run type-check
✅ Tests: make test, make test-e2e, make build all pass
Ready for deployment!
