[Track] Deterministic simulation scenario library for agent training/evaluation

[SMC17]

Goal

Build reusable deterministic multi-node scenarios to evaluate protocol and agent behaviors.

Deliverables

• Scenario catalog with explicit seed/config profiles.
• Success/failure criteria per scenario.
• Trend-aware reporting for stability and performance drift.

Acceptance

• Simulation gate runs scenarios with reproducible outcomes.
• Artifacts include machine-readable summary and reasoned failure diagnostics.
• Scenarios map to concrete protocol risks (consensus timing, load, adversarial patterns).

Linked Epic

• [Vision Epic] Agent-native XRP Ledger daemon in Zig: execution program #4

Child delivery queue: #21 (good first issue), #22 (expert-only). Suggested order: #21 -> #22.

New child issue for this track: #37 (manifest-driven multi-scenario runner). #21 and #22 are complete.
