test(yawning-titan): compose RAES conformance with simulator-specific probes

[Brad-Edwards]

Objective

Compose published RAES backend conformance with YAWNING-TITAN-specific mapping, control, and leakage probes.

Scope

• Validate the adapter manifest with the published RAES model.
• Run the applicable published backend profile and canonical fixtures against a fully constructed RuntimeTarget.
• Add adapter-local probes for source-ledger coverage, source/profile identity, reset/seed/clock controls, action and observation projection, evaluator projection, cleanup, and portable-output leakage.
• Define a small deterministic PR suite and a broader study/readiness suite.
• Emit machine-readable RAES diagnostics, conformance reports, evidence references, and declared weaknesses.
• Keep adapter probes additive; do not create a second profile table, fixture corpus, schema registry, or manifest authority.

Acceptance criteria

• Every applicable published fixture passes or returns a justified machine-readable unsupported result.
• Every manifest capability links to passing evidence.
• Success and failure paths for all four backend surfaces are leak-tested.
• The selected source protocol's reset, stochastic, action, observation, reward, and terminal controls have executable probes.
• Clean-install conformance runs in CI under the yawning-titan extra.
• Reports distinguish backend conformance from source-protocol reproduction and research claims.
