Linked production route

Scope Global

Security

Local evidence Checksum/control replay + Security and implementation hints

Browser-checkable work only

Boundary No live source proof

Official state remains external

Why this exists

Know what can be trusted before wiring the value into production.

Webhook signatures pages in ValidoHub are tool-first. This reference layer explains the checks, fixtures, developer handoff, and source-system limits so teams can integrate the live workbench output deliberately.

Use for Implementation planning

Choose normalization, storage, masking, and fixture strategy.

Use for QA and CI fixtures

Keep pass, review, malformed, and edge examples beside the code.

Use for Developer handoff

Copy the live tool JSON instead of reverse-engineering display text.

Browser checks

Local evidence the workbench can expose.

Check Checksum/control replay

Use the workbench for current evidence.

Check Security and implementation hints

Use the workbench for current evidence.

Check Batch and import debugging

Use the workbench for current evidence.

Official boundary

Where local validation must stop.

Boundary Inputs stay browser-local; treat copied output as developer test data.

Boundary No live network, registry, bank, payment, or tax-office lookup is performed.

Integration traps

Small mistakes that create expensive debugging later.

Trap Never log raw personal, payment, or secret values when masked output is enough.

Trap Use stable machine fields and error codes; do not parse translated UI strings downstream.

Trap Keep malformed, short, wrong-prefix, and bad-checksum fixtures in CI.
