Integration Fieldnotes

Short, evidence-led studies of the moments when two systems meet: the request, the reply, the record, and what a person should be told.

IF—01 / Wallet state

A signature is not a staking outcome

Separate wallet approval, network submission, confirmation and account state.

IF—02 / Safe retries

The reply timed out. Did the action?

Design retries for state-changing requests without quietly duplicating the effect.

IF—03 / Event delivery

Arrival order is not business order

Handle duplicate and delayed events while keeping records coherent.

IF—04 / Data freshness

Every status has a time window

Explain when a value was observed and when it needs checking again.
