# clink-headless.sh — local-decode checks for `amy offer info` / `amy debit info`.
#
# These verbs are pure pointer decode (no network), so this suite needs no relay:
# it asserts that amy decodes the canonical CLINK interop vectors (the same fixtures
# the quartz ClinkInteropTest uses) to the right fields, in both success and error
# paths. The round-trip verbs (`offer request`, `debit pay`, `debit budget`) need a
# live CLINK service and are out of scope here.
#
# Usage: ./clink-headless.sh [--no-build]
