Elevated decision risk1 synthetic confirmed constraint matched · payment-api in scope

Matched explicit rule · synthetic accepted fixture

Partner access tokens expire after 15 minutes.

This synthetic decision is marked accepted and owner-confirmed by Mina Chen for the walkthrough. The fixture citation is hand-authored; no repository or external source was fetched.

Fixture change: 15 * MINUTE → 24 * HOUR. The latter is forbidden by the cited rule.

Agent context protocol / example 02

Read the graph before you write.

A coding agent fetches the relevant systems, decisions and constraints. Its receipt makes that context legible in review.
