Customer App configuration boundaries
Use this reference to identify which layer owns a Customer App variation and how to verify it safely. It describes responsibility and diagnostic boundaries; it does not publish configuration names, values, private response shapes, or instructions for changing a live environment.
Do not infer that every value available to one application read is public, safe to expose, or supported as an implementation input. Use only an approved public configuration surface and keep undocumented data out of examples, logs, screenshots, and tickets.
Configuration layers
| Layer | Resolved when | Can affect | Owner |
|---|---|---|---|
| Packaged release | Before distribution | App identity, native registrations, packaged presentation, and release mode | Release/build owner |
| Project and service | For the intended environment | Broad capability and presentation policy | Authorized Ordering/configuration owner |
| Business | For the selected business | Business-specific availability and choices | Business/configuration owner |
| Customer and order context | During the current journey | Accessible screens, required steps, and current options | Customer/order state plus Ordering authorization |
| Device and provider | At runtime or handoff | Permission, platform behavior, and external completion | Operating system/provider |
Build-time and runtime responsibilities
Packaged release inputs must be correct before distribution. Runtime project, business, customer, order, permission, and provider context can then narrow or alter what the customer sees. A correct packaged release does not by itself prove runtime eligibility, and a visible runtime control does not prove authorization or provider completion.
Some presentation and context inputs can refresh while the app runs; native registrations and packaged capabilities require a supported build. Do not assume a runtime value can install native code or change release identity.
How layered inputs affect a result
Verify the result in stages:
- Identify the intended release.
- Have the authorized release/configuration owner confirm the intended environment and project outside the app.
- Satisfy current business, customer, and order prerequisites.
- Verify the state Customer App presents.
- Complete any operating-system/provider handoff through its owning contract.
- Verify the final visible Customer App result.
This model does not promise one universal precedence order. A project policy, business state, account/order requirement, device permission, or provider result can each prevent a later stage.
Treat unknown value shapes as unavailable
If a required input is missing, stale, malformed, or not in an approved public shape, treat the capability as unverified and unavailable for implementation. Do not coerce the value, guess a default, infer authorization from presentation, or copy the raw data into diagnostics. Escalate the redacted condition to the owner of the public contract.
This is the required implementation posture; it is not a guarantee that every current runtime path already fails closed for malformed input.
Verify a configuration-dependent experience
- Use an isolated non-production environment.
- Record the exact app release and intended project using approved public identifiers only. Do not seed, switch, or persist a project inside the app as part of this verification; current stored-project behavior is not a certified public contract.
- Establish one expected capability state through the authorized owner.
- Verify presentation separately from authorization and external completion.
- Repeat only with a deliberately different approved context.
- Stop if an undocumented value, unexpected shape, or sensitive field appears.
A useful value-free decision record is: release recognized, project policy approved, business/customer prerequisites satisfied, device supported, control presented, action authorized, and final result observed. Keep each stage separate rather than reducing them to one enabled flag.
Failure ownership and troubleshooting
The expected screen or control is missing
Verify the release, intended project, business, account/order prerequisites, and platform support in that order. A missing control does not by itself reveal which configuration layer denied it.
The same release behaves differently for another business or customer
Treat business and customer/order context as separate owners. Compare only approved, synthetic contexts and do not copy raw customer or configuration data.
A change appears in one environment but not another
Confirm the exact release and authorized project/business owner. Do not promise immediate refresh or cache timing; keep the change unverified until the visible result is observed in the intended environment.
The app reaches a device or provider boundary and stops
Verify the operating-system permission or provider handoff separately, then return to Customer App and verify its final visible state. Client configuration does not prove provider readiness or completion.
An undocumented or unexpected configuration form appears
Stop. Do not normalize, guess, log, screenshot, or publish it. Retain only the minimum redacted release/environment/capability context and escalate to the security/configuration owner.
Security and privacy
Use only approved public configuration surfaces. Keep credentials, private identifiers, raw configuration, customer/order/payment/session data, precise coordinates, and provider callback material out of URLs, examples, logs, screenshots, and tickets. Documentation verification must remain read-only and must not initialize providers or change a live project.
When to recertify
Recertify after changes to packaged/native inputs, the public configuration contract, value shapes/defaults/normalization, project-selection or persistence behavior, navigation/provider/permission boundaries, the configuration-security disposition, or App/shared-components/API authority pins.
