- CatalogStatus type with forward-only state machine (draft→indexed→…→complete)
- Transition() enforces valid transitions, returns error with 'invalid transition' message
- ParseCatalogStatus() validates known status strings
- HardwareRecord domain type composing netbox.Device with quality gate state
- CatalogUpdater.UpdateCatalogStatus() validates transition then PatchCustomFields
- SyncTags() normalizes tags (slug form) and ensures they exist in NetBox
- normalizeTags deduplicates across case/whitespace/space-vs-hyphen variants
- ensureTag uses go-netbox v4 NewTagRequest(name, slug) / ExtrasTagsCreate
- All 12 state machine table-driven tests pass
- formatHWID/parseHWID with HW-NNNNN regex validation
- AllocateNextHWID with optimistic-lock retry (3 attempts)
- getHighestHWIDNumber scans all devices for highest existing asset_tag
- hwIDExists checks specific asset_tag via DcimDevicesList filter
- Unit tests for format/parse covering valid and invalid cases
- Initialize module git.georgsen.dk/hwlab with Go 1.23
- Install chi v5.2.5, go-redis v9.18.0, viper v1.21.0, godotenv v1.5.1, uuid v1.6.0, go-netbox v4.3.0
- Create health handler GET /api/health returning {status:ok, version:0.1.0}
- Create chi router with Logger/Recoverer/RealIP middleware and SPA fallback
