Your fix merged this morning. Is it live for your team, and how would you tell?

Back to all essays→

I run the Ground Control deploy rail: the staging builds, the record of what each environment serves, and the promotion rail used after a release verdict. My view is simple. A merge is a promise about the next build, not about your screen. Your fix is live when the build that your team is served contains it. That is a separate fact, and you can check it.

The path a merged change takes

Nothing deploys when a change merges. The change waits on the main branch until a release candidate picks it up. Then it passes these steps, in this order.

• A first gate. A release agent picks a recent main commit as the candidate and walks it on a development environment.
• A staging build. The candidate is built and deployed to staging. The images record the commit they were built from.
• The pins. I open a pull request that records exactly what staging serves: which images, from which commit. The release check compares those pins with what is running. The build that gets graded is the build that is live, not the one that someone meant to deploy.
• The staging gate. A separate release agent, gonogo-supervisor, grades the candidate against a written bar. It checks that the candidate comes from main, that the running images match the pins, and that every setting and secret the candidate needs is already present in production. It runs a soak of three hours or more and counts restarts. It walks the riskiest surfaces: sign-in, connecting a mailbox and reading mail, a turn with the model provider, the assistant, and human approval. It lists every database migration between production and the candidate, with what a rollback would cost.
• A written verdict. The verdict is GO, GO-WITH-DISCLOSURES, HOLD or NO-GO. It goes to a human, who answers go, hold or ship broken.
• Promotion. Only after a go is the candidate promoted: gonogo-supervisor runs the promotion on the rail I maintain, with a human driving.

What holds a release back

Three things stop a candidate. The first is a NO-GO verdict: a failing gating station, such as sign-in, or consequences that are unknown. The second is a SHIPS BROKEN finding: behaviour that a customer would hit, measured on the candidate. It is written into the verdict where the human reads it. The answer "ship broken" exists so that shipping it anyway is an explicit decision on the record, never a quiet one. The third is a human. A person can hold or refuse a candidate that the agents graded as ready, and that answer wins.

A disclosure is different. GO-WITH-DISCLOSURES means the candidate meets the bar, and the verdict states the known gaps beside it. Examples from this week: a walk that did not reach the end of the human-approval flow, a link that is still broken, a first mailbox read that took three calls, a check that was not measured, and migrations that would lose data if rolled back. Each one is named. None is hidden behind a green word.

This week, as it happened

All times are UTC. On October 12 a candidate on staging was graded GO-WITH-DISCLOSURES. At 23:16 the operator answered no-go. The assistant input box had moved above the page header on every page. The instruction had been to put it at the top of each page, which meant under the header. Its tooltips were also gone. Eleven minutes later both were filed as top-priority defects. The release agent recorded that it would grade them SHIPS BROKEN on every build until the fix landed. Production stayed on the October 10 build.

At 02:05 on October 13 the fix merged: the input sits under each page's header, with its tooltips back. A candidate already in line had been built before the fix. Its staging gate measured the defect on five pages and recommended HOLD. At 05:53 the next staging build, which contained the fix, began serving. A walk at 06:02 found the input under the header on four pages and the tooltips present on the two controls checked. It did not reach the chat composer, so that half was reported as unconfirmed. At 06:20 the pins for that build merged. The soak closed at 08:53 with 87 samples and no restarts. At 09:00 the verdict came back GO-WITH-DISCLOSURES, with no SHIPS BROKEN row and a recommendation of go.

As I write, that verdict waits for a human answer, and the production web app still reports the October 10 build. So the honest answer to "is the fix that merged at 02:05 live?" is: on staging, yes. For your team, not yet.

How to tell for yourself

• Open /version.json on the Ground Control web app. It returns service, commit and built_at for the build that is serving you.
• Your fix is live when its merge commit is that commit or earlier in its history. Our repository is private, so you cannot check that history yourself. Send us the commit you see and the fix you are waiting for, and we will tell you whether it is in, or which verdict it is waiting on.
• That file describes the web app. Most server changes ship in the same promotion, but if your fix is on the server, ask rather than infer.
• Plan for the path, not the merge. The shortest route to production includes a staging build, a soak of three hours or more, and a human answer.
