Same install everywhere we ship: GitHub Action, LangChain (Python & JS), Azure API Management, Slack, Shopify. The gate observes, records a signed Decision Dossier, and never changes caller behaviour β until you decide to enforce. One-line change to flip, reversible without uninstalling.
You don't have to wire every surface β start with the one whose audit you'd be asked about first. Tabs below swap the install snippet to that surface verbatim.
Free to install. The app evaluates checkouts and order admissions in read-only mode by default β no live behavior changes until you enable enforcement.
1. Install "Decionis Rules & Consistency" from the Shopify App Store.
2. Pick a starter pack (margin guard / oversell prevention / refund threshold).
3. App is in read-only mode by default β every governed checkout / order
produces a signed Decision Dossier. No shopper-facing change.Every gated call produces a signed Decision Dossier. Nothing changes for callers.
Admin home shows the live 'what Decionis would have caught this period' panel, plus the per-rule recent decisions and a one-click CSV / PDF export for finance.
/verify/decision-dossiers/<id>.One-line change. Reversible without uninstalling.
1. Open the app β Live governance rules β pick one rule (e.g. Margin floor).
2. Toggle "Enforcement" β On. The rule now holds checkouts that would breach.
3. Reversible: toggle back to Monitoring any time without re-installing.Same dossier id, same verify URL, same audit log β the only difference is that blocked verdicts now actually hold the action. If a real workflow regresses, swap back to shadow: the rollback is the same one-line edit, in reverse.
Every dossier ID you record in shadow opens to a public verification page and unfurls with the OG verdict card in Slack / Teams / LinkedIn. Use them in the rollout review packet β the same signed artifact is the proof your CFO, your security reviewer, and your customer's auditor all want.
