EP-018: Multi-Property & Chain — Phase 1 Hardening
Phase 1 hardening sprint, 2026-04. Branch in
hmp-web-dashboard. Not yet pushed.
The multi-property epic gained one item in Phase 1: a Playwright E2E test suite that exercises the property switch flow and verifies tenant + property scope is enforced end-to-end. The work also surfaced one architectural finding about the API gateway proxy that's worth recording even though it's not a bug.
C3 — Multi-Property Isolation E2E Tests
Branch: feat/multi-property-isolation-tests (in hmp-web-dashboard)
What was added
e2e/tests/19-multi-property-isolation.spec.ts — 5 Playwright tests, all passing on the
first run. The suite uses two seeded properties (A and B) under the same tenant, with two
test users: one with access to A only, one with access to both.
| # | Test | What It Verifies |
|---|---|---|
| 1 | Login to property A, switch to property B, verify reservations list refreshes | Property switch updates active scope; cached state cleared |
| 2 | User with access to A only cannot fetch property B reservations via API | Tenant + role enforcement on direct API calls |
| 3 | Reservation created on property A is not visible on property B | Tenant scope on writes |
| 4 | HK task on property A floor 3 is not visible to property B users | Property scope on real-time channels (WebSocket rooms) |
| 5 | Folio close on property A doesn't trigger night audit on property B | Event topics are property-scoped |

Result
No bugs were found. The isolation boundary works as designed at every layer the tests exercise. The suite is now in CI as a regression net.
Architectural Finding (not a bug — documenting for future authors)
While reviewing the auth flow, the C3 work surfaced this from proxy.service.ts:407-408 in
hmp-api-gateway:
// Override any client-supplied X-Property-Id with the JWT claim
headers['x-property-id'] = req.user.propertyId;
headers['x-tenant-id'] = req.user.tenantId;
This means a user cannot spoof a different propertyId by setting the header in their own request — the gateway always overwrites it with whatever's in their JWT. To switch properties, the user must hit the auth endpoint that issues a new JWT bound to the new propertyId.
The implication for downstream service authors: treat x-property-id as authoritative for
the request. Don't add redundant validation against request body propertyId fields — the
header is already trusted. Documenting in
architecture/multi-property-isolation.md
so future endpoints don't reinvent the check.
Open Gaps
These were known before C3 and remain open:
- Cross-property reads within a tenant (chain manager viewing all 5 properties) are not yet covered by isolation tests. EP-018 has stories for chain rollups (US-018-005, US-018-006); tests will follow when those land.
- Audit log scoping.
auth-service'sauditLogtable scopes by tenantId only, not property. Acceptable for now since auditLog is admin-only, but worth noting for SOC 2 prep.
Summary
| Story | Status before | Status after | Notes |
|---|---|---|---|
| US-018-001 (Property Switch) | Built | Built | C3 verified end-to-end |
| US-018-002 (Tenant Scope) | Built | Built | C3 verified at API + WebSocket layers |
| US-018-007 (Chain Rollup) | Not Started | Not Started | Out of Phase 1 scope |
No story-level status promotions. The value added is regression coverage, not new features.
