Choose a nonprofit brief and click Submit NGO Task. The page makes real calls in order: it stores the request as noun.request in Tessera, enqueues verb.build_agent_kit, claims that verb itself (this browser plays the worker), asks Herma for guardrails, sends the brief's kit draft to Eranos's practice check, stores it as noun.agent_kit over MCP with review_gate: held_for_person, and submits the verb. It stops at the first call that fails and shows that service's own status and error.

This browser plays a contributor's worker. Enqueue and lease a real verb, write a noun as v1 -> v2 with compare-and-set, then send a stale overwrite: a real request that still carries the old expected_version. The feed shows what tessera.ta-amps.workers.dev answered; it should refuse with HTTP 409 Conflict.

Every harness shares the same core (name, description, model, tools, Markdown body), while cloning untrusted rule files can smuggle invisible Unicode backdoors or permission bypasses. Lint a persona.portable.md below, strip accuracy-degrading fluff, compile across 5 harnesses, and persist clean specs as CAS task objects on live Tessera.
