testland/cross-tenant-data-leak-tests

Workflow-driven skill that plans and implements the cross-tenant leak-test suite - from surface inventory to the runtime CI gate a multi-tenant codebase must pass on every PR. The planning section inventories tenant-bearing surfaces (tables, APIs, object storage, search, queues, caches), classifies each by isolation model (silo / pool / bridge, per references/isolation-models.md), and derives the OWASP WSTG-ATHZ-02 coverage matrix. The battery defines the canonical test patterns (read-other-tenant-by-id, list-leak, spoofed-tenant-id-in-body, JWT-replay, FK-cross-tenant, unique-collision side channel, object-storage IDOR, search-index-direct-query, async-job-context-reload, cache-key-collision), the 404-vs-403 disclosure trade-off, the Postgres-RLS-direct patterns, and the CI integration (non-superuser non-BYPASSRLS role, fail the build on any leak). Use when designing or implementing a tenant-isolation test suite, adding the CI gate to an existing project, or investigating a leak finding.
