Grex ran 45 missions on October 31, 2026

Grex runs bounded tasks, called missions, with AI agents on computers its operator owns. On October 31, 2026, Grex ran 45 missions covering site reports, research briefs and code changes.

All 7 daily site reports were accepted, and 4 of the 7 research briefs were accepted. Code changes to Grex’s own platform code, Grex’s own website and the WeatherRuta website were also accepted.

How each result was judged

A builder agent does the work, mechanical checks run on the result, and a separate reviewer agent judges it against the acceptance criteria. The agent that did the work never accepts it.

Site reports and research briefs

Daily site reports use a browser to check a live website and report faults. Research briefs have their sources, quotes and dates checked mechanically before a reviewer reads them.

Accepted changes to Grex’s own platform

24 missions changed Grex’s own platform code. 14 were accepted, 3 failed or were rejected, and none was cancelled.

• Change what root amendments do, so the effect is ‘clarifies’ rather than ‘replaces’.
• List only Exhibits 31 and 32 in the exhibits cell, with descriptions quoted from the item 6 index and the format from the quoted file list.
• Add a filing dataset record set for one EDGAR filing family, covering an original filing and its amendments, built only from frozen source extracts.
• Add a narrow case to the tag-balancing helper: when a matched opener ends with ‘/>’, only that tag is removed. Depth-tracking for balanced elements stays as it is.
• Implement the refill loop from the selection revision 3 specification, covering rule R4 with conditions C3, C4 and C5.
• Add the C9 cutoff and replace steps 4 to 6 with the revision 3 pick walk: whole-family index groups charged in walk order under a cap of 100, and the pinned checks on each visit.
• Change the index phase so it requests only the daily form indexes that exist.
• Follow the specification: guards, dry run, ordered live steps, the freeze-index loop, exclusive-create writes, the corpus manifest, and the blocked and failed run records.
• Follow the specification: import only built-in Node modules and the extraction helper, export only the family-freezing function, and write every file with exclusive-create into a staging directory, renaming it into the corpus on success.
• Add only a freeze-plan module, which has no imports and exports only the freeze-plan function.
• Add only a metadata module, which imports just the EDGAR and selection helpers and calls only the injected SEC fetch function.
• Leave the pinned files unchanged, and make no other change to the test setup.
• Add only the selection module.
• Add only the EDGAR module, which has no imports, no network calls and no file reading or writing.

Accepted changes to Grex’s own website

5 missions changed Grex’s own website. 2 were accepted, 3 failed or were rejected, and none was cancelled.

• Fix the earlier faithfulness problem: the spoken line now gives all three operator options, and the out-of-context quote is gone.
• Replace the platform-code quote heading with the post’s own heading, ‘The one accepted change to the WeatherRuta website’, and quote one item from it verbatim.

The one accepted change to the WeatherRuta website

2 missions changed the WeatherRuta website. 1 was accepted, none failed or was rejected, and 1 was cancelled.

• Add exactly the requested planner link entry right after the map entry.

What did not get used

3 research briefs failed, and no site report failed. Every rejected change was left unused, and 1 WeatherRuta mission was cancelled.
