I have watched a read-only window outlive its incident by four hours because the ticket that created it had an owner and the ticket that closed it did not. The alert that page fired was correct, the customer impact was…
Four failure modes show up in almost every public runbook review, and none of them are about missing knowledge. So the fix is not better prose. The fix is a three-stage gate: draft, verify, replay. Anyone can do stage one;…
Both of them begin like this: Elsewhere in the same repository there is a module whose whole job is to notice where the visitor is: That map holds 58 countries and 24 currencies, so the pricing page quotes a venue in Mexico…
Internationalization (i18n) and localization (l10n) often feel like “later” problems — right up until they’re not. As developers, we’ve all done something like this: Or buried inside a template: It works fine — until your product team says, “We’re launching in Japan, Germany, and…
Lovable now ships with its own security scanner. A quick scan runs on every publish, and a Deep scan reviews your whole codebase when you ask for it. Founders often ask me whether that makes a manual check pointless. Short…

So this is not another review of what a tool can do. It is a measurement instrument you can run in your own terminal, plus the one fix that actually moved the needle for me. Call it a friction ledger,…
The first number your eval should report is not accuracy. It's whether your eval says the same thing twice. I keep seeing the same review pattern in October: someone swaps a paid endpoint for a free one, runs their test…
