Three rebuilt workers, three checkable receipts

Three rebuilt computers completed research trials and produced receipts that could be authenticated without contacting Grex.

New to Grex?

Grex coordinates AI teams on computers you control. You give a team an assignment, set its limits, and review the evidence of what happened.

Component key: the names used in this blog

You set a mission → a team does the work → checks assess the evidence → Grex records the result.

Mission: An assignment with a target, a time window, a budget, and rules for stopping.
Control plane: The central service that coordinates missions and records budgets, decisions, evidence, and outcomes.
Nidus · plural: Nidi: A worker computer you control. The fleet is the collection of these computers.
Sidecar: The Grex software on a worker computer that receives work, runs agents, and reports results.
Manipulus · plural: Manipuli: A reusable capability pack: the agent roles and tools for a job such as research or website growth.
Actor: An individual agent role within a pack. A planner chooses steps, a scout gathers evidence, and a drafter prepares output.
Strategist / supervisor: An agent role that reviews progress and proposes whether to continue, change approach, or ask for help.
Verifier / referee: Checks and a separate reviewer that assess an output and its evidence. The producer does not supply the final verdict.
Doctrina: Grex’s curated shared memory of known facts and completed work, used to ground plans and avoid repeats.
Artifact / brief: A saved work product. A brief is a short report with sources and an explanation of the finding.
Verified / ratified: Verified means specified checks passed. Ratified means Grex accepted the result under its rules. Neither proves more than those checks establish.
Receipt: A saved record of work, measured cost, evidence, and outcome. A signed receipt can be authenticated; its claims still need sound evidence.

All three Grex worker computers were rebuilt and enrolled again today. Each then completed the same competitor-research trial and produced a signed result record.

Grex coordinates AI teams on operator-controlled computers. Rebuilding those machines tested whether the system depended on accumulated manual fixes.

Research after a fresh enrollment

The reset removed worker state while preserving provider access. After enrollment, the three computers completed trials with 33, 28, and 49 accepted items.

All three recorded $0.00 of metered spend. That figure describes measured charges, not the cost of hardware, subscriptions, or engineering effort.

Checking receipts without contacting Grex

A receipt is the saved record of a mission’s result. The three receipts were exported and checked on the operator’s laptop without contacting Grex.

The checks used a separately obtained public key set. All three signatures verified.

That establishes that the exported records could be authenticated independently of the running service. It does not, by itself, prove every underlying research claim correct.

Two other trials tested completion and refusal

An unattended mission accepted 44 competitor briefs against a target of one. It concluded and wrote its own report after a person activated it.

A later mission inspected product pages and confirmed that the sites were live. It rejected the product-identity claim three times and stopped without an externally supplied judgment.

Onboarding still stopped at a real defect

The installation rehearsal failed at its withdrawal step. Grex refused to withdraw a duplicate mission with zero outputs because it counted 52 verified outputs belonging to another mission.

The safeguard was counting at team level when it needed to count within one mission. This was the exercise’s third distinct integration failure, reaching its predefined stop condition.

The rehearsal was suspended. It produced eleven filed defects, with onboarding-path fixes made that day. The completed research trials did not make the unfinished installation exercise a pass.
