Adds the transactional email pipeline driven from the Odoo SMTP relay so
new sign-ups get a Velxio-branded welcome and existing users can reset a
forgotten password without us running our own outbound mail server.
Backend:
- PasswordResetToken model: one-time, SHA-256-hashed (plain text never on
disk), TTL 60 min, marked used_at on consume to prevent replay.
- POST /auth/forgot-password — anti-enumeration (always 200 + generic
message), rate-limited 3/hour/user.
- POST /auth/reset-password — verifies token, hashes new password,
atomically marks token used.
- /auth/register hooked with asyncio.create_task to fire welcome mail —
registration is never blocked on Odoo being up.
- New service app/services/odoo_mail.py: async httpx wrapper, fire-and-
forget, swallows every error so the request lifecycle stays clean.
- Settings ODOO_URL / ODOO_API_KEY / ODOO_MAIL_TIMEOUT_S /
PASSWORD_RESET_TOKEN_TTL_MINUTES / PASSWORD_RESET_RATE_LIMIT_PER_HOUR.
Frontend:
- /forgot-password page (single email field + "check your inbox" state).
- /reset-password?token=XYZ page (new password + confirmation, redirects
to /login?reset=ok on success).
- "Forgot your password?" link + green confirmation banner on /login.
- authService gains requestPasswordReset() and resetPassword().

Adds 4 nullable columns to the users table so deployments that wire an
external billing system (e.g. velxio.dev with Odoo) have a place to cache
subscription status. Self-hosters never write these — defaults are safe
(no paid features unlock).
- models/user.py: is_paid_subscriber (bool, default false), subscription_status
(str|None), subscription_period_end (datetime|None), odoo_partner_id
(int|None, indexed).
- main.py: 4 ALTER TABLE statements appended to the legacy_migrations list
so existing deployments auto-migrate on next boot.
- schemas/auth.py: extend UserResponse with the 3 user-visible fields
(is_paid_subscriber, subscription_status, subscription_period_end). The
frontend useAuthStore already persists the whole UserResponse, so these
surface automatically without any frontend changes upstream.
odoo_partner_id stays internal — clients don't need it.
Zero behavioural change for existing OSS deployments.
Three small, backwards-compatible hooks let anyone with private features
(velxio.dev's analytics, custom integrations, paid tiers, …) layer them
on top of the open-source build without forking files.
Backend (app/main.py):
- After standard router registration, try-import an optional `app.pro`
module exposing `register_pro(app)`. ImportError is silently swallowed
(the OSS image doesn't ship `app.pro`, so this is a no-op there).
Frontend:
- EditorToolbar: new optional `rightSlot` prop renders extra elements
after the built-in right-group buttons (mirrors the existing
`centerSlot` pattern).
- main.tsx: dynamic `import('@pro/index')` gated by VITE_PRO_BUILD env.
When unset (OSS build), the branch is dead-code-eliminated and no pro
chunk is emitted.
- vite.config.ts: `@pro` alias resolves to `src/__pro_stub__/` by default.
Private builds set `VITE_PRO_BUILD=true` and `PRO_OVERLAY_PATH=<path>`
to point at their real overlay tree.
- src/__pro_stub__/index.ts: 1-line no-op `mountPro` so TypeScript and
Vite resolvers stay happy in OSS builds.
Verified: `npm run build:docker` succeeds; `npm test` passes 1161/1162;
the OSS bundle (43 MB) contains zero references to `__pro_stub__`,
`@pro`, or `pro/index` (verified via `grep dist/`).

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).

Replace arduino-cli with ESP-IDF 4.4.7 for ESP32 compilation — Arduino-compiled
firmware crashes in QEMU (9-28 reboots) while ESP-IDF boots cleanly (0 reboots).
The new espidf_compiler translates Arduino WiFi/WebServer sketches to native
ESP-IDF C code, compiles with cmake+ninja, and merges into 4MB flash images.
Key changes:
- ESP-IDF compiler: translates WiFi.begin/WebServer to esp_wifi/esp_http_server
- ESP-IDF project template with QEMU-optimized sdkconfig (DIO, 40MHz, no WDT)
- WiFi status parser for ESP-IDF serial logs (wifi_status, ble_status events)
- IoT Gateway HTTP reverse proxy for ESP32 web servers
- WiFi/BLE auto-detection from sketch content + visual status icons
- Static IP 192.168.4.15 matching slirp DHCP first-client range
- Docker: new espidf-builder stage with ESP-IDF 4.4.7 toolchain
- 157 tests covering WiFi/BLE for both ESP32 (Xtensa) and ESP32-C3 (RISC-V)
