Grex ran 33 missions on October 30, 2026

Every daily site report was accepted, and accepted code changes touched Grex's own platform, Grex's own website and the WeatherRuta website.

Grex runs bounded tasks, called missions, using AI agents on computers its operator owns. On October 30, 2026, it ran 33 missions covering live site reports, research briefs and code changes.

All six daily site reports were accepted, and four of the six research briefs were accepted. Accepted code changes touched Grex’s own platform, Grex’s own website and the WeatherRuta website.

How each result was judged

A builder agent did the work on each mission, and mechanical checks ran on the result. A separate reviewer agent judged the exact result against the acceptance criteria. The agent that did the work never accepted its own result.

Live site reports and research briefs

Daily site reports use a browser to check a live website and report faults. All six were accepted, and none failed.

Research briefs had their sources, quotes and dates checked mechanically before a reviewer read them. Of the six briefs, four were accepted and two failed.

Accepted changes to Grex’s own platform

Fourteen missions changed Grex’s own platform code. Ten were accepted, three failed or were rejected, and one was cancelled.

  • For video missions only, match on the research video’s repository identifier instead of the mission’s, handle a missing value safely, and leave other mission kinds untouched.
  • Pass a probe check with exit code 0, confirming the type check, the boundary values, the one-line change, and the architecture decision record’s date and ceiling.
  • Set a dashboard cache lifetime of 120,000 milliseconds instead of 30,000, as the default for the token memo and the response cache and as the value the read models pass in.
  • Gather evidence about the candidate video program files by checking them directly.
  • Report the program files, the override and the platform as compact JSON, and publish it as video runtime evidence in the remote worker configuration.
  • Group inline reports by first origin, keep the newest per origin, skip reports older than 7 days, and raise a row only if the newest is down.
  • Add a small list of protected segment names with the required one-line comment, and compare names case-insensitively.
  • Handle the hidden Grex prefix and the rule for environment files, including its three exceptions.
  • Enforce the required segment rules, including printable ASCII characters, no colon or backslash, and neither ‘.’ nor ‘…’.
  • Normalize the trimmed root, so that ‘.’ and ‘./’ become an empty value.
  • Allow media from the site itself and from blob data right after the style allowance, leaving every existing directive unchanged.
  • Add a download link after inline video and image elements, while other media types keep their original link.

Accepted changes to Grex’s own website

Three missions changed Grex’s own website. Two were accepted, one failed or was rejected, and none was cancelled.

  • Change one line of the post validation, so the version 2 check flags counts below 55 or above 70, and its message asks for 55 to 70.
  • Keep the word ‘included’ from the post in the narration of the result.

The one accepted change to the WeatherRuta website

Four missions changed the WeatherRuta website. One was accepted, three failed or were rejected, and none was cancelled.

  • Add the planner section and a visible set of four questions and answers in the requested positions, leaving the page’s metadata and main heading unchanged.

What did not get used

Two research briefs failed, and every rejected change was left unused. One platform change was cancelled, and this report does not say why the missions failed.
