See it fix a bug under you
Four fictional companies, each with its own stack, its own Git host and its own workspace — because Sarcio ships onto sites it doesn't control. File the bug with the reporter widget on the page, approve the AI-drafted fix, and watch the running app heal: no reload, no redeploy, state intact.
Alpine & Oak Outfitters
The storefront that undercharges
A pricing module applies every coupon twice. The fix is replacement code, hot-swapped into the running page — while the cart, quantities and coupon survive untouched. That's a module patch, and state survival is the whole trick.

The status page that can't load its own metrics
The metrics endpoint demands a range parameter the dashboard never sends, so every widget dies with a 400. A signed server patch defaults it at the boundary and the page lights up green — enforced by a self-hosted sidecar that fails closed, with the permanent fix opened as a Bitbucket pull request.

The signup wizard that dead-ends at step 3
Finance required a tax id the wizard never collects, so every signup dead-ends at step 3. The patch lands in a Java backend while a user sits on that step — and the very same click succeeds, form state and all. The permanent fix is a GitLab merge request.

Fernwood Journal
The journal whose subscribe button can't be clicked
A real WordPress, and the one demo carrying both tiers. The subscribe button ships permanently disabled — removing that is a DOM patch, and when the reviewer rates it elevated it needs a second, different approver before it goes live. Behind it, the newsletter REST route is fixed through the Sarcio plugin.

Every fix is signed, previewable, and reversible.
What you approve in a demo is the same pipeline a customer runs: Ed25519-signed patches, preview-before-live, one-click retire, and a real pull request with the permanent change. See the full lifecycle.
