Two gaps found by exercising the MSP pilot path live on a throwaway
multi-tenant instance:
1. CheckAccess granted any authenticated principal access to the default
org, so a token bound to a client org could read the provider's own
default-org estate if it leaked from a client site. Org-bound tokens
now fall through to the explicit binding check for the default org;
authenticated users and legacy unbound tokens keep default-org access,
and binding "default" explicitly still grants it.
2. The webhook private-target allowlist (instance-wide system setting)
only ever reached the default org's notification manager on
startup/reload, and only the request-context org on settings update.
Tenant orgs' webhooks to private targets (per-client Gotify over VPN,
the canonical MSP alert route) failed SSRF validation with no org-side
remedy, and any allowlist died with a restart. Settings updates and
reloads now fan out to every live tenant manager via the new
MultiTenantMonitor.ForEachMonitor, and tenant monitors inherit the
persisted allowlist and public URL at creation.
Both fixes verified live: org-bound token vs default org returns 403;
client-org webhooks to a private target succeed after restart and for
orgs created after the allowlist was saved. MSP.md validation checklist
gains the default-org probe and the allowlist guidance; MULTI_TENANT.md
documents the binding semantics. Contracts updated for api-contracts,
security-privacy, and monitoring with adjacency notes for
agent-lifecycle, storage-recovery, and performance-and-scalability.
Implements multi-tenant infrastructure for organization-based data isolation.
Feature is gated behind PULSE_MULTI_TENANT_ENABLED env var and requires
Enterprise license - no impact on existing users.
Core components:
- TenantMiddleware: extracts org ID, validates access, 501/402 responses
- AuthorizationChecker: token/user access validation for organizations
- MultiTenantChecker: WebSocket upgrade gating with license check
- Per-tenant audit logging via LogAuditEventForTenant
- Organization model with membership support
Gating behavior:
- Feature flag disabled: 501 Not Implemented for non-default orgs
- Flag enabled, no license: 402 Payment Required
- Default org always works regardless of flag/license
