Runbook Rot: Three Fingerprints of Stale CI Docs and the Check That Catches Each
A runbook is the only document in your repo that gets read at 3 a.m., under adrenaline, by someone who trusts it. When the code is stale you get a b…
The Agent Wrote a Test That Mocks the Function Under Test
The test file passed. The function it was supposed to cover was broken. The mock was the giveaway. CI went green. Coverage on the new module jumped…
When the agent calls the failing test "pre-existing" and merges anyway
The PR comes in. CI is red. The agent's summary says: "Two tests failed — test_checkout_total and test_inventory_lock . Both were already failing on…

AI code review in CI when tests pass but design fails
My coding agent can write a feature, add tests, and hand me a green build. It can also put the right behavior in the wrong place. The application wo…
Зелёный пайплайн ничего не доказывает. Семь способов, которыми quality gate пропускает брак в прод
if roc_auc < 0.85: exit 1 — примерно так выглядит quality gate почти в каждом ML-пайплайне, который мне попадался. В обычном CI то же самое — кол…

Growing Pains with Five Repositories: Gitlinks and Dual CI

A Scorecard for Agent Diffs: Fixture Digests, Seed Replay, and Failure Signatures

Markdown woes: Looks right, is wrong
Your Markdown can be perfectly rendered and completely wrong Markdown has an unfair advantage: it looks trustworthy. A table lines up, the headings…
Green Coverage, Broken Inverse: A Round-Trip Gate for Agent Patches
Agent patches can raise line coverage while destroying invertibility. A merge bar that only asks “did pytest exit 0?” will accept a codec that no lo…
Four Identical Red Runs: One Was Our Watchdog Working, Three Were Its Corpse

Don't Merge the First Green Check: Hooks, Fixtures, and a Flake Budget
