Stream loop — run topology & telemetry

+

The two-arm SWE-bench stream: frozen (F) vs supervised-learning (L), same instance in the same slot. This snapshots the request graph, the model routing, and the measured curve. Live run = glm-5.2 self-supervision · CONC=1

+ +
+

NOT a delegation tree. This experiment does not have a supervisor spawn workers a/b/c. The driver samples k=4 workers independently and in parallel (no supervisor involved), scores them, keeps the best — and only if it failed does the supervisor write one advice plan for a retry. The supervisor is a reviewer at the end, not a dispatcher at the start. (The delegation-tree topology — supervisor → workers — exists in the codebase via supervise()/coordination-MCP, but this run doesn't use it.)

Every model box calls one endpoint — api.z.ai/api/coding/paas/v4 over HTTPS; every docker box runs locally, network-isolated. In THIS run all three model roles are the same model (glm-5.2 = self-supervision); in the cross-strength config the worker is a cheaper model and only the supervisor is glm-5.2. Arms F and L share t0–t3 (same repro, same 4 candidates); they diverge only at t4 (raw-failure retry vs supervisor-plan retry). Timings per phase are in the ledger (imagePullMs, wallMs, judgeMs); per-model-call timestamps are not yet emitted — see the note below.

+

The supervisor's plan is grounded ONLY in execution-verified evidence (the failing diff + the jailed failure output) — never the worker's self-report — so the credulity hazard measured in the arena cannot occur. Every plan is stripped of code and audited for hidden-test leaks.

Prior full run (day-1, n=20) — reference

Day-1 arm L = memory recall only (no supervisor). L−F = −1 (noise). The live run adds the supervisor, testing whether execution-grounded advice moves the curve.
