1 / Lost input
A failed request should not erase the brief.
The form keeps its values until a persisted receipt is returned. A timeout or server error shows a useful message and gives the visitor a retry.
Development case / Project intake
A form that survives
the real world.
A form can look finished and still fail on a slow connection or a second click. This case shows how input recovery and safe retries make a reliable inquiry workflow.

2 / Duplicate submissions
One intention should create one record.
A submission lock stops repeated clicks. The server also enforces a unique Idempotency-Key, so retrying a request after a lost response returns the same reference.
3 / False confidence
The server has the final say.
Client checks help the visitor. Server validation protects the stored data. A success message appears only after the brief has been saved, not simply after clicking a button.
More than a visual fix.
The live form on the home page uses a server endpoint and a persistent database. The sandbox above intentionally simulates the old and improved behavior so you can compare them without creating test records.
