Home / The record / The amendment frame

The paragraph that counts the mechanisms is replaced. The count moves to fifteen and EdDSA is the addition. The history of which edition added what is otherwise kept, so the sentence an architecture note quotes has to be updated rather than rewritten.

What it asks

State the mechanism set your estate may use as fifteen named mechanisms, with EdDSA among them, and make the list match the edition you hold. Where a controlled document quotes a count, the citation must name the amendment as well as the base standard. A count carried from the 2018 text is now one short.

What the amendment does

Replaces the paragraph after Note 4 in the Introduction. So the 2018 wording is superseded for this clause.

Who it binds

The owner of the internal cryptography standard or the approved algorithm list.

Evidence an auditor samples

• The controlled cryptography standard, with its edition and amendment line (document control)
• The approved mechanism list, showing fifteen entries or a recorded subset (architecture)
• The change note that moved the count, with its approval date (change record)

The test you can run

Open the approved list and count. If it says fourteen, or cites the base edition without the amendment, the document lags the text.

Common failures

• The count is corrected in the policy but not in the design note engineers actually read.
• The amendment is cited in a footnote while the list still reflects an older edition.

How to close it

Take the approved list, add the amendment to its citation line, and check that every mechanism named is one the text specifies. Where a system uses a mechanism that is not on the list, record it as an exception with an owner rather than leaving the list short. Start with the controlled cryptography standard, with its edition and amendment line and let the row close when it exists with a date and a named holder.

Where it sits against the base standard

The base standard carries an earlier version of Introduction, Note 4, and the amendment replaces the paragraph named above. A citation to the base edition alone points at wording that no longer applies, which is the defect this record exists to catch.
