tegwick 5734b280c6 T06: out-of-band self-verification ...

Checks written as plain functions over a serialized Evidence Pack, outside the
framework - no Oracle, no Runner, no Verdict aggregation. 12 tests that they
hold, 12 that they can fail. All four td://self identifiers covered.

The substantive check is verdict reproducibility from S3 evidence alone,
asserted on failing runs as well as passing ones.

F-0003 (open): actor isolation leaves no trace in ordinary evidence - the
self-test catches a shared memory store only because the harness plants
per-actor canaries. Isolation is currently a property of a scenario written
to expose it, not of runs in general. The mirror-image case is noted too: a
guarantee enforced by construction cannot be verified by observing real runs,
so four green self-tests are not four equivalent proofs. Carried to T10.
