10000app #0070 · PMF pre-judgment 76/100 · cross-context leakage is costly, while framework isolation and red-team suites remain strong substitutes

Shared runtime.
Separate context.

Describe abstract allow and deny boundaries, then generate direct, concurrent-switch and stale-session cases with synthetic canary assertions. This is a test-design artifact—not a scanner—and it never connects to an agent, reads memory or executes a tool.

    Generated assertions are only a plan. A passing test proves only the fixture and harness behavior you actually ran; it does not prove tenant isolation, prevent prompt injection, inspect memory, certify security or cover production concurrency.
