The rack prototype lived behind /racklab with no backend. It now becomes a
third design_type alongside network and electrical, sharing the app shell:
same header, same left rail, same right panel, same design switcher. App
branches the renderer on design_type.
Backend
- racks / rack_devices / rack_cables, all design_id-scoped.
- rack_devices.device_id -> pending_devices is the primary link. Those rows
survive approval and node deletion, so unracking never removes the device
from the Device Inventory. node_id -> nodes is a second, optional link used
only for live status and for matching network-link imports. Both are
ON DELETE SET NULL and label is denormalized, so a rack keeps rendering
after an inventory purge.
- GET /racks, POST /racks/save (full-state upsert + prune, same contract as
canvas/save), GET /racks/inventory.
- POST /scan/pending adds an inventory entry by hand, for hardware no scan
can discover.
- design_type is now validated and actually branched on; the schema comment
calling it vestigial is gone.
- Design delete unwinds rack rows explicitly (SQLite does not always honour
the cascade); design copy duplicates racks, mounts and patches with fresh
ids and re-points the cables at the copies.
Frontend
- /racklab and RackLab are removed; no dual maintenance.
- Rack types lifted into @/types; rackSerializer maps the snake_case wire
shapes to them, narrowing every enum on the way in.
- The store gains load/save, dirty tracking and an editSeq, so racks get the
same explicit Save and the same opt-in autosave as the logical canvas.
- Header, sidebar and inspector adapt in rack mode: canvas-only actions are
hidden, Add Rack / Patch / cable visibility / type filter / Import links
take their place, the sidebar body becomes the inventory tray, and the
footer counts racks, mounts, cables and free U.
- rackTheme derives the rack palette from the active app theme rather than
declaring one per theme, so a new theme works here for free. Per-rack
chrome stays user-editable; only its default comes from the theme.
- New Canvas gains a Kind picker (hidden when copying, since a copy inherits
the source kind).
Tests: 24 backend, 5 frontend files (store, persistence, networkLinks,
rackTheme, rackSerializer) plus DesignModal coverage for the Kind picker.
ha-relevant: maybe
Frontend rack renderer is portable; the FastAPI routes and SQLAlchemy models
are standalone-only by the persistence/transport split. Discuss before porting.
