I shipped CaOutcome with 204 passing tests and a README example that gave thirteen wrong answers. Every test passed the collection by parameter. Maester pipes it, and PowerShell unrolls a piped array.

I found MC1448379 while hunting for my next post: on November 3, every memberOf group, administrative unit and auto-assignment policy stops updating. Microsoft says grep for the word. I wrote a parser.

On 10 September my UDM’s WAN port renegotiated to 100 Mbps and stayed up. No alert fired, and the house sat at 178 ms for hours. I traced it to a cable and wrote a poller to catch it next time.

One VM running qBittorrent was pulling about 98% of my WAN traffic. I capped it in qBittorrent, shaped the WAN with Smart Queues and aimed a UniFi throttle at it. Only some of those limits bind today.

I sent a query from my IoT VLAN to 8.8.8.8 for a name only my Pi-hole knows, and Pi-hole answered. Then I went after the encrypted DNS paths a port 53 redirect can’t touch.

One allow rule on my IoT VLAN hadn’t passed a packet in two months, and it took two fixes to find out why. This is the rule set, the test I ran from inside the VLAN, and the two holes it found.

In August I moved my UDM Pro to UniFi’s zone-based firewall and left it alone for two months. When I read the policy list back, three rules pointed at a machine that stopped being Plex a while ago.

On October 19 I found a Message Center post: Entra stops honoring layout CSS in company branding on October 26. The news listed ten properties. Learn lists 58, display included, so I built a scanner.

My Widget detection exits 0 with nothing on stdout, so Intune installs the app, can’t find it and reports 0x87D1041C. This index maps each portal symptom to the IntuneScriptLab command behind it.

REM-RETURN-EXIT has run hourly for three weeks, and its probe file holds 168 records, all detections. My validation kit deploys experiments like it to Proxmox VMs and reads them back.
