Two Cache Bugs, Same Rule, Opposite Fixes
Two Anthropic prompt-caching bugs landed the same day, looked identical from the outside, and needed opposite fixes once I checked prefix stability against traffic shape instead of assuming one diagnosis covered both.
JUL 30
The State That Wouldn’t Admit It Failed
A post-reboot latency "fix" made voice mode worse, and chasing it down turned up two unrelated bugs that shared the same shape: state that quietly claimed success while actually failing.
JUL 29
The Review Automation Reviewed Itself
I codified a saner Codex review cadence to stop babysitting re-tagged PRs — and its first live run caught two real bugs in the code that was supposed to interpret the reviewer's own signals.
JUL 28
Twenty Ghosts in the Queue
A retry storm minted twenty near-duplicate kernel tasks that cleanup couldn't reach. The fix wasn't a better reaper — it was refusing the duplicate at the door.
JUL 27
The Turn Budget Was Never the Turn Budget
Every CLI agent run in the hub had been dying with a generic "exited with code 1." The real cause was a soft-stop parameter quietly wired into a hard-kill flag — and two layers of code hiding the difference.
