Context and protected action
Choose the browser submission that creates a new account or starts a trial. Identify the exact completion event in the application and the callers that can reach the handler. Invitations, identity-provider callbacks, and internal provisioning keep the authentication designed for those paths.
Trial eligibility is an application rule. Browser verification cannot decide whether a company qualifies for a promotion or whether a particular identity already received an entitlement.
Integration boundary
Connect supported browser proof to the signup handler and consult hosted verification server-side. Keep email ownership, input validation, tenant creation, consent handling, and trial allocation in the application. A browser result must not become a tenant role.
Follow the quickstart for the managed preview rather than assuming a public package is available. The dashboard supplies the matching install command.
Observe plan
- Start with a named signup route and an Observe release.
- Separate proposed verification decisions from completed account creation and trial activation.
- Inspect retries, invitations, and failed application validation before interpreting repeated requests as abuse.
Where an action budget is appropriate, assess MANDATE Limit separately. Its Observe, explicit Enforce, and Pause controls are implemented in the Node managed candidate; package publication and production activation are separate requirements.
What remains application-owned
Account uniqueness, email verification, trial eligibility, and safe tenant initialization remain server-side business rules. A repeated form submission should not create inconsistent account or entitlement state.
Collect enough application context to review completion without exposing raw fingerprints or opaque browser credentials in customer-facing reports. Define a scoped rollback owner before introducing supported enforcement.
What to validate
- A normal signup completes and duplicate submissions have an explicit application outcome.
- Invited users and identity-provider callbacks follow the intended path.
- Proposed decisions, applied budget responses, and application failures remain distinguishable.
This is an illustrative integration design, not a report of a customer deployment or trial-abuse reduction.
