This commit allows Velxio to run embedded in Elemes lesson pages via iframe
with PostMessage communication for code loading, circuit state, and serial
monitoring.
Phase 2 of the OSS / pro split. The hook seams introduced in Phase 1
let stateless routes (compile, libraries, simulation, iot_gateway)
run without the auth/DB stack importable. Now we actually delete the
stack:
app/api/routes/auth.py
app/api/routes/projects.py
app/api/routes/admin.py
app/api/routes/metrics.py
app/models/{user,project,usage_event,password_reset_token}.py
app/schemas/{auth,admin,project}.py
app/core/{dependencies,security}.py
app/database/session.py
app/services/{metrics,odoo_mail,project_files}.py
app/utils/{geo,slug,boards}.py
Private deployments (velxio.dev) get the same modules back via the
velxio-prod overlay: pro/backend/app/api/routes/auth.py etc. are
COPYed onto /app/... at container build time, and register_pro()
includes their routers + registers the lifespan/metrics/auth hooks.
main.py shrank back to the stateless router includes + a single
`run_lifespan_startup()` call. The Phase-1 try-import block that wired
record_compile / get_current_user_id from upstream is gone — those
adapters live in pro now.
Verification:
OSS only: 20 routes (compile, libraries, simulation, gateway).
OSS + pro: 94 routes — identical to pre-refactor velxio.dev.
Net change: -2400 lines from OSS, all of which moved to velxio-prod's
overlay. Self-hosted OSS users lose accounts + project persistence;
the Phase 4 .vlx export/import gives them a portable replacement.

The project save/load pipeline only persisted a single `board_type`, so
multi-board workspaces silently lost every board except the active one
on save, and wires referencing the dropped boards' IDs orphaned to the
canvas corner on reload. An audit of the production backup found 74/306
projects (24%) with at least one orphaned wire and 174/301 non-trivial
projects whose code was still the default Blink template — strong signal
that users save once and never re-save.
Backend
- Add `boards_json` column on `projects` with idempotent ALTER TABLE in
the lifespan migration list.
- New `FileGroup` schema + `file_groups` array on
ProjectCreate/Update/Response. Legacy `files`/`code` kept for back-compat.
- `project_files.py` now uses `{pid}/{groupId}/{filename}` subdirs via
`read_groups`/`write_groups`. Legacy flat layouts are auto-promoted on
read; legacy single-list `files` only updates the active group, leaving
other boards' files intact.
- `_persist_files_from_body` honors file_groups → files → code priority.
Frontend
- `useSimulatorStore.addBoard` accepts an optional `explicitId` so
saved board IDs can be restored verbatim (wires reference IDs literally).
- New `loadProjectState({boards, fileGroups, components, wires,
activeBoardId})` action: tears down current boards, recreates from the
payload, restores file groups atomically, recalculates wire positions
on the next frame, and refreshes the Interconnect.
- `useEditorStore.replaceFileGroups` for atomic multi-group restore.
- `SaveProjectModal` and `ProjectByIdPage`/`ProjectPage` now go through
`buildSavePayload` / `buildLoadPayload` (handles pre-backfill projects
by synthesising a default board from `board_type`).
Auto-save (#useAutoSaveProject hook)
- 2.5s debounced silent PUT triggered ONLY when an authenticated user
has a `currentProject` with a UUID. State hash detects real changes
vs. UI-only churn; baseline is reset on project load so the just-loaded
state isn't immediately re-saved.
- `beforeunload` flush via `fetch keepalive: true` (supports PUT +
credentials, survives unload).
- Compact status indicator in `AppHeader` (idle/dirty/saving/saved/error).
Backfill script (one-off, idempotent)
- `backend/scripts/backfill_boards_2026_05.py` populates `boards_json`
for legacy projects. Heuristic per project, based on which board IDs
the wires reference:
Case A — wires only ref 'arduino-uno' but board_type ≠ uno:
rename id→board_type and rewrite wire endpoints.
Case B — single-board normal: keep verbatim.
Case C — multi-board: recreate one board per distinct ref, infer
kind by stripping trailing -N suffix.
Also moves any flat files into the active board's group subdir.
Stdlib-only, runs from host or `docker exec`.
Docker
- `Dockerfile.standalone` now copies `backend/scripts/` into the image
so the backfill is callable via `docker exec velxio-app python
/app/scripts/backfill_boards_2026_05.py --apply`.
Verified locally on the restored production backup (363 projects):
33 Case A, 316 Case B, 14 Case C, 135 wire endpoints renamed, 0 orphans.
Re-running the script after apply skips all 363 (idempotent).

Track per-user, per-project, and per-board usage to inform pricing tier
decisions. Adds an admin dashboard with KPIs (DAU/WAU/MAU, totals,
success rate), time-series charts for compiles/runs, board family +
FQBN breakdowns, "board diversity" pie chart (key freemium signal),
top users/projects, and per-country breakdown via Cloudflare's
CF-IPCountry header. Admin can now also view private projects.
Backend:
- New UsageEvent table (append-only event log with user_id, project_id,
event_type, board_fqbn/family, country, error_kind, duration_ms)
- Aggregate counters on User (total_compiles/runs/errors, last_active,
signup_country, last_country) and Project (compile/run/update counts,
last_compiled/run timestamps) kept in sync by MetricsService for O(1)
dashboard reads
- 10 admin endpoints under /api/admin/metrics/{overview, timeseries,
boards, board-diversity, top-users, top-projects, countries,
users/{id}, projects/{id}}
- POST /api/metrics/run for client-side run telemetry
- Country detection via cf-ipcountry header (no DB / no API calls)
- Auto-migrations in lifespan for legacy DBs
Frontend:
- recharts-powered Dashboard tab with KPI cards and 4 charts
- New Boards tab with per-family + per-FQBN breakdown
- Country column with flag emoji on Users tab
- Top countries card on Dashboard
- compileCode now forwards project_id; Run button reports via WS

Backend:
- project_files.py: read/write sketch files to /app/data/projects/{id}/
- GET /api/projects/{id}: load project by ID (public = anyone, private = owner only)
- create/update write files to disk volume; delete removes them
- ProjectResponse includes files[] list loaded from disk
Frontend:
- /project/:id canonical route -> ProjectByIdPage
- ProjectPage (legacy /:username/:slug) redirects to /project/:id after load
- SaveProjectModal sends files[] and navigates to /project/{id} after save
- DATA_DIR env var in both compose files
