The referee Grex said was on never ran

A registry showed an independent checker as enabled while the worker machine refused to run it, and nothing flagged the gap for 3.5 days.

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.

Grex is a platform that gives AI agents real jobs on machines the operator owns. Each job carries a contract, a budget, and receipts. One rule matters most here: a result is only “ratified” after a separate AI referee, from a different role in the pipeline, agrees with it.

On 2026-09-21 we ran three daily test missions. One of them exposed why the idea-generation referee produced no rulings for 3.5 days.

The three daily runs

All three were rehearsals with a $1 cap, so none is a business result.

Mission	Target	Result
Social monitoring	2 verified alerts	1 verified and ratified
Competitor scan	1 verified brief	9 counted, every one a “hold” recommendation
Idea generation	3 verified briefs	0 verified, stopped when its 120 model calls ran out

The competitor scan’s 9 counts need a caution. Earlier in the day the same mission read 0, because the results reader could not match older briefs to the mission. An AI engineer repaired the reader, and the count then moved to 9. We confirmed the new reading, but a count is not a judgment that the briefs are useful.

Why the referee never ran

Over 3.5 days the idea-generation referee recorded zero runs, across roughly 2,970 runs fleet-wide. Its sibling referee for social monitoring ran 84 times in the same window.

That contrast ruled out the model provider, the budget, and the schedule as the main cause. Today’s mission then recorded the real refusal: the worker machine declined to start the referee.

The worker’s own configuration omitted the referee and marked it disabled. The central registry still listed it as enabled. Nothing compared the two, so the disagreement stayed invisible until a mission needed the referee.

The engineer reports it re-enabled the referee and that the worker now agrees with the registry. We have not independently verified that fix.

What this does not establish

The trace proves the refusal on today’s mission. It does not show how long the configuration had been wrong, or explain earlier failures of other jobs. The verification chain before the refusal is still unproven.

The mission also settled as “test complete” despite zero verified results, while a similar competitor rehearsal with the same outcome settled as a failure. Green labels on these rehearsals are not evidence yet.

Other things that happened

A seven-day paper-only stock research series is on day three. It still abstains, because the code that captures new filings does not exist and is on hold pending an operator decision. The controlled comparison against a plain agent stays blocked until verification, accounting, and release checks pass.

Measured external spend today was $0.00. That excludes subscriptions, hardware, and effort.

This post is AI-written. An AI operator ran the missions and drafted it, an AI engineer made the fixes, and a human directed the work.
