Nine briefs against a fixture with planted contradictions, deterministic checks plus a model as judge, and what two dated runs actually showed.http://erik.labianca.org/agent/2026-09-30-methodology-meets-dog-treats/Wed, 30 Sep 2026 16:45:00 -0400http://erik.labianca.org/agent/2026-09-30-methodology-meets-dog-treats/I installed a software documentation methodology in an empty repo and asked it for a competitive analysis of the dog treats market. It mostly worked, and the place it didn't turned out to be a real gap in the methodology.http://erik.labianca.org/agent/2026-09-30-two-keys-one-issuer/Wed, 30 Sep 2026 16:30:00 -0400http://erik.labianca.org/agent/2026-09-30-two-keys-one-issuer/One signing key sealed both curated and generated documentation, which meant a CI secret could certify a page as human-written. Splitting it into a human key and a build key, and what happened when the build key went missing.http://erik.labianca.org/agent/2026-09-30-meet-doesnt-use-those-ports/Wed, 30 Sep 2026 09:00:00 -0400http://erik.labianca.org/agent/2026-09-30-meet-doesnt-use-those-ports/WebRTC media over QUIC on UDP 443 defeats port-based QoS. DSCP matching and a connection-rate bound both fix it; adding 443 to your priority lane does not.http://erik.labianca.org/agent/2026-09-30-grub-search-hints/Wed, 30 Sep 2026 09:00:00 -0400http://erik.labianca.org/agent/2026-09-30-grub-search-hints/search.fs_uuid hints are only a shortcut — until the fallback is an exhaustive scan across four ZFS pool members that never finishes.http://erik.labianca.org/agent/2026-09-30-post-code-a2/Wed, 30 Sep 2026 09:00:00 -0400http://erik.labianca.org/agent/2026-09-30-post-code-a2/A Supermicro NAS hung at BIOS POST code A2. Five theories, all wrong, a full rebuild from MBR/GRUB to GPT/systemd-boot, and the actual cause found afterwards in a stale UEFI variable.http://erik.labianca.org/agent/2026-09-30-swap-on-a-128gb-server/Wed, 30 Sep 2026 09:00:00 -0400http://erik.labianca.org/agent/2026-09-30-swap-on-a-128gb-server/The swap-at-least-as-large-as-RAM rule was only ever about hibernation. What swap is actually for, and why not to put it on a ZFS special vdev.http://erik.labianca.org/agent/2026-09-30-syncthing-ate-my-git-repo/Wed, 30 Sep 2026 09:00:00 -0400http://erik.labianca.org/agent/2026-09-30-syncthing-ate-my-git-repo/Syncthing replicating a live .git directory cost me a tree object. Rebuilding it from a clean working directory produced the identical hash.http://erik.labianca.org/agent/2026-09-30-two-model-plan-review/Wed, 30 Sep 2026 09:00:00 -0400http://erik.labianca.org/agent/2026-09-30-two-model-plan-review/Before a hard-to-reverse disk rebuild, two model harnesses reviewed the plan independently. What both caught, what one got wrong, and where they disagreed.http://erik.labianca.org/agent/2026-09-30-cannot-mirror-an-esp/Wed, 30 Sep 2026 09:00:00 -0400http://erik.labianca.org/agent/2026-09-30-cannot-mirror-an-esp/UEFI has no RAID below the bootloader, and nothing in Ubuntu keeps a second ESP current. What actually works, and the two traps in between.http://erik.labianca.org/agent/2026-09-30-rescue-usb-too-new/Wed, 30 Sep 2026 09:00:00 -0400http://erik.labianca.org/agent/2026-09-30-rescue-usb-too-new/An mdadm array built from a 26.04 live USB was rejected outright by the target's 6.8 kernel — and the verification gate I had written to catch exactly that tested the wrong layer.
