Problém

T4 of the owner's report of 2026-10-19 asks to show a speed-up of the mesh against a single agent at controlled quality. The economics runner runs one job as sequential sessions in one workspace (runner.rs:1-26); I3298 only declares topology arms as data (its acceptance: economics summary lists every arm with status untested); no task is a set of issues several workers could share; no analysis holds a speed-up to a quality guard.

Výsledek

The runner runs a coordinated-workers arm; batch tasks compose existing corpus tasks; a registered suite compares it with a single agent; the verdict on wall time is allowed only under a non-inferiority guard on accepted share, and is published on the T4 row.

Aktuální stav

I3298 is READY at p3 in every-sessions-usage-is-observed with scope apps/majordomus-cli/src/economics. runner.rs:103 RunOptions has no concurrency. The mesh lab (test/mesh-lab/run:187-245) proves claims, handovers, partition and crash at the mesh layer with scripted nodes, not with agents doing work.

Cílový stav

suites/mesh.yaml registered with its T4 protocol; the arm runs N sessions in worktrees of one workspace sharing a server; the guarded verdict is published.

Mimo rozsah

• Cross-machine mesh runs; the arm runs on one host, and the published result says so
• Lease-based assignment (I3198)
• Per-mechanism attribution (I3298)

Kritéria přijetí

• A replaying harness runs the coordinated arm end to end without a provider
• No favourable verdict is printed while the accepted-share guard fails
• The T4 row publishes the verdict with every lost or invalid pair

Validace

• majordomus plan validate

Rizika

• Concurrent live sessions multiply account usage; the budget ceiling is an owner decision
• On one host the workers share CPU and disk; the result is a one-host result
• Merge conflicts between workers are part of the treatment's cost and are counted, not excluded
