CSA Loom — the Microsoft Fabric experience for Azure tenants where Fabric isn't yet available: lakehouses, warehouses, notebooks, semantic models, Activator rules, Data Agents, across Commercial, GCC, GCC-High, and DoD IL5

Parity gap — /onelake OneLake catalog

Loom route: /onelake (rendered by apps/fiab-console/app/onelake/page.tsxItemsByTypePane) Fabric reference: Microsoft Fabric OneLake catalog — https://learn.microsoft.com/fabric/onelake/onelake-catalog Loom screenshot: temp/parity/page-onelake-loom.png — 5 real data items rendered Captured: 2026-05-26

Phase 3 — Side-by-side gap matrix

# Fabric OneLake catalog element Loom OneLake catalog element Status Severity
1 Page header "OneLake catalog" Present with full subtitle present
2 Filter input "Filter items by name or description…" input with search icon present
3 + New item button NewItemDialog (2-pane Fabric-style picker) present
4 Item card grid: lakehouses, warehouses, KQL stores, eventhouses, mirrored DBs 5 real items rendered: KQL database, Eventhouse, Lakehouse (RAG agent platform - Document corpus), Warehouse (test_DW), Lakehouse (test lakehous) present + live data
5 Item type badge "Real-Time Intelligence" / "Data Engineering" / "Data Warehouse" category badge per card present
6 Last-modified date "Updated MM/DD/YYYY" per card present
7 "Browse" / "Open" action on each card Card itself is a Link to /items/[type]/[id] present
8 Endorsement badges (Promoted / Certified) Not visible missing MAJOR
9 Sensitivity label per item Not visible missing MAJOR
10 Owner avatar + name per item Not visible missing MINOR
11 Domain badge Not visible (workspace info not surfaced on card) missing MINOR
12 Type filter (lakehouse vs warehouse vs eventhouse) Single text filter, no type-chip filter partial MINOR
13 "Get URL" / "Copy OneLake path" per item Not present missing MAJOR
14 Lineage hint / icon Not present (lineage is under /governance/lineage) acceptable
15 Empty state "No data items in this tenant yet" with hint to create via + New present

Phase 4 — Functional verification

Control Source Result
Filter input Real client-side filter via useMemo on displayName + description OK
+ New item dialog NewItemDialog opens Fabric-style 2-pane picker OK
Item card link href /items/[type]/[id] resolves to per-item editor OK
Backend /api/items/by-type?type=lakehouse&type=warehouse&... — real Cosmos query against itemsContainer with IN filter on itemType OK
Auth handling 401/403 → renders SignInRequired instead of error OK — honest

Honest grade

Grade: B

Reasoning: - Phase 3: 0 BLOCKER, 3 MAJOR (no endorsement, sensitivity, copy-OneLake-path), 4 MINOR. - Phase 4: 0 BROKEN — every visible control wires to a real backend, 5 live items are real Cosmos records. - Cards are clickable and resolve. Filter is functional. + New is real.

Not A because Fabric OneLake catalog surfaces endorsement + sensitivity prominently (key governance metadata) and offers "Copy OneLake path" as a primary card action. Also missing per-card owner.

  1. Add endorsement badge (Promoted / Certified) per card.
  2. Add sensitivity label chip.
  3. Add per-card overflow menu with "Copy OneLake path", "View lineage", "Get URL".
  4. Add type-chip filter row above the search input.
  5. Add owner avatar + workspace+domain on each card.
