+# Phase 1 Plan 04: HW-ID, Quality Gate, Tag Sync, Catalog Updater Summary
+
+**One-liner:** Sequential HW-XXXXX ID allocation with optimistic-lock retry, forward-only CatalogStatus state machine enforced via Transition(), AI tag slug-normalization and NetBox sync, and CatalogUpdater wiring quality gate to NetBox PATCH.
+
+## What Was Built
+
+### `internal/netbox/hwid.go`
+- `formatHWID(n int) string` — formats integer as `HW-NNNNN` (zero-padded 5 digits)
+- `parseHWID(s string) (int, error)` — parses `HW-NNNNN` with strict regex `^HW-(\d{5})$`
+- `(c *Client) AllocateNextHWID(ctx) (string, error)` — queries highest existing asset_tag, increments, checks candidate is unclaimed, retries up to 3 times on conflict
+- `getHighestHWIDNumber` — scans `DcimDevicesList(Limit=1000)` for highest HW-XXXXX number
+- `hwIDExists` — checks `DcimDevicesList(AssetTag=[candidate])` for conflict detection
+
+### `internal/inventory/quality_gate.go`
+- `CatalogStatus` string type with 5 constants: `StatusDraft`, `StatusIndexed`, `StatusNeedsResearch`, `StatusResearched`, `StatusComplete`
+- `validTransitions` map encodes the only permitted forward transitions
+- `(s CatalogStatus) CanTransitionTo(next)` — O(n) lookup in allowed list
+- `Transition(current, next)` — returns error with "invalid transition" message on rejection
+- `ParseCatalogStatus(s)` — validates string against validTransitions keys
+- `AllStatuses()` — returns statuses in lifecycle order
+
+### `internal/inventory/types.go`
+- `HardwareRecord` — domain struct composing `netbox.CustomFields`, `CatalogStatus`, HWID, NetBoxID, Name, AITags
+
+### `internal/inventory/catalog_updater.go`
+- `CatalogUpdater` — wraps `*netbox.Client`
+- `UpdateCatalogStatus(ctx, deviceID, current, next)` — calls `Transition()` for validation then `PatchCustomFields` with `{"catalog_status": string(newStatus)}` — T-04-01 mitigation enforced here
+
+### `internal/netbox/tags.go`
+- `normalizeTags(tags)` — lowercases, slug-converts (spaces→hyphens, non-slug chars stripped), deduplicates; "USB Cable"/"USB cable"/"usb-cable" all produce "usb-cable"
+- `tagNameToSlug(name)` — lowercase + trim + space-to-hyphen + strip non-[a-z0-9-_]
+- `TagRef` — holds ID, Name, Slug for a resolved NetBox tag
+- `(c *Client) SyncTags(ctx, tags)` — normalizes then ensureTag for each
+- `ensureTag` — `ExtrasTagsList(Slug=slug)` to check existence; `ExtrasTagsCreate(TagRequest{Name,Slug})` to create new

+## Test Results
+
+| Test | File | Result |
+|------|------|--------|
+| TestFormatHWID (3 cases) | hwid_test.go | PASS |
+| TestParseHWID (7 cases) | hwid_test.go | PASS |

+| TestParseCatalogStatus (5+1 cases) | quality_gate_test.go | PASS |
+| TestNormalizeTags | tags_test.go | PASS |
+| TestTagNameToSlug (4 cases) | tags_test.go | PASS |
+
+Integration tests (AllocateNextHWID live, SyncTags live): **SKIPPED** — placeholder token (correct behavior, will run once real HWLAB_NETBOX_TOKEN is set).
+
+`go build ./...`: PASS
+`go test ./internal/...`: 16 PASS, 3 SKIP (integration guards), 0 FAIL
+
+## Deviations from Plan
+
+### Auto-fixed Issues
+
+**1. [Rule 1 - Bug] normalizeTags needed slug conversion for dedup correctness**
+- **Found during:** Task 2 GREEN phase (TestNormalizeTags failure)
+- **Issue:** Original `normalizeTags` only lowercased/trimmed — "USB Cable" and "usb-cable" remained distinct (2 results, not 1)
+- **Fix:** Changed `normalizeTags` to delegate to `tagNameToSlug` internally — ensures space-to-hyphen and non-slug stripping before dedup; test comment says these three should all produce "usb-cable"
+- **Files modified:** internal/netbox/tags.go
+- **Commit:** 1f9621f
+
+## Known Stubs
+
+None. `ensureTag` uses real go-netbox v4 `NewTagRequest`/`ExtrasTagsCreate` API. `AllocateNextHWID` uses real `DcimDevicesList` API. No stubs in any shipped code.
+
+## Threat Surface Scan
+
+No new network endpoints introduced. All trust boundary mitigations from plan's threat model are implemented:
+- T-04-01: `UpdateCatalogStatus` enforces `Transition()` before any `PatchCustomFields` call — bypass impossible through this path
+- T-04-02: `normalizeTags` strips injection surface before NetBox write — all AI tag strings pass through slug normalization
