Dead-code sweep. Functions flagged unreachable by golang.org/x/tools/cmd/deadcode
and confirmed unused across pulse, pulse-enterprise, pulse-pro and pulse-mobile by
adversarial cross-repo verification. Cross-module reachability was checked
explicitly (only pkg/ exported symbols are importable by other modules; internal/
packages and _test.go files are not). go build, go vet and test-compile all pass.
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
