On October 11, Phantom added one required check that blocks a merge if any expected test job is missing, failed, canceled or skipped by surprise.
On October 11, 2026, Phantom merged a change that adds a single check called "Merge Gate". Its pull request says the gate requires a successful classifier and exactly the set of test jobs that should run for that kind of change. A site-only change needs the site job. Every other change needs every full test group.
"Fail closed" means the gate fails when a job is missing, failed, canceled, neutral or ran when it should not have. The description says it does not replace any of the fifteen full qualification jobs.
The pull request also says the gate is not yet required by GitHub branch protection. The next step it lists is to protect the main branch with this check once the exact commit has passed the hosted checks and review. That means the gate exists, but on this day it was not yet enforced by GitHub.
Two other Ashlr repositories merged related changes minutes earlier. Ashlr Core Efficiency added an explicit merge verification contract, naming the typecheck, build and test commands and four files the verifier depends on. Ashlr Cortex removed a workflow file from its contract that did not exist, and kept the same required checks.
The core-efficiency description is candid about one test. A performance test measured 509 milliseconds against a 500 millisecond limit while the machine was busy, then 379 milliseconds when it was idle. The pull request says it did not relax the limit and that CI is the arbiter.
One required check that summarizes many jobs is easier to enforce than a list of fifteen. Make that summary fail when a job is missing, not only when a job fails. A skipped job is also a quiet way to lose coverage.
Ask how a vendor decides that a change is safe to release. Good answers name the checks, say what happens when one is missing, and admit what is not yet enforced.
Look at your own main branch. List the checks a change must pass, and then ask what happens if one of those jobs never runs.
