What GeraWitness Will Be: The Safety Layer for Agent Actions

Quick answer. GeraWitness is a human-review layer that plugs into GeraNexus and any other agent-commerce flow. High-risk agent actions route through trained human reviewers before committing; low-risk actions flow through automatically. The effect is to make agent commerce safe at scale without losing speed where it does not matter. Not shipping today; design public; pilot 2027.

The product in a paragraph

Agents are going to execute real-world actions on behalf of users. Some of those actions will be high-stakes: large payments, medical bookings, legal commitments, estate decisions. Trusting the model alone for all of those is the wrong risk profile. GeraNexus transactions flagged as high-risk route through GeraWitness, where a trained reviewer sees the proposed action, the context, and the consent chain, and approves or rejects before commit.

Risk tiers

  • T0 — auto: standard bookings, low-value transactions. No human review.
  • T1 — sampled: random 1-5% sample reviewed for calibration. Does not block commit.
  • T2 — mandatory pre-commit: high-value, medical, legal, irreversible. Human must approve before commit.
  • T3 — hard stop: categorically refused classes. Model cannot override.

Who the reviewers are

Full-time Gera trained reviewers in multiple time zones, plus a vetted contractor pool for surge capacity. Reviewers see the proposed action, the user’s consent token, the agent’s reasoning trace (where available), and the relevant category- specific policy. They approve, reject, or ask for more context (which delays commit but doesn’t kill it).

What GeraWitness is not

  • Not a dispute resolution service. Disputes happen after the fact; GeraWitness is pre-commit.
  • Not content moderation. Moderation is model-level; GeraWitness is action-level.
  • Not training. The reviewer signal does not train the underlying LLMs.

How it fits with GeraNexus

GeraNexus emits a risk tag with every transaction. Tier-T2 and above gate through GeraWitness. The review result is added to the signed receipt trail, so downstream audit shows a reviewer approved the action.

Timeline

  • Q3 2026 — policy drafting, tier taxonomy, reviewer workflow design.
  • 2027 — pilot within the Gera network only.
  • 2028 — open to third-party agent platforms via SDK.
  • 2030 — general availability with compliance-grade SLAs.
