 - log: wizard.log.md
 
 ## what was built
 
 - wizard.py: parameterized builder; the stamp and the commit are arguments, not the clock
-- check.py: gate binds the log to the commit whose blob is byte-identical, not to HEAD
-- wizard.log.md: self-describing entry carrying its own stamp and its carrying commit
+- check.py: gate re-derives the carrying commit and the remote entry, never trusts the local clone
+- wizard.log.md: self-describing entry naming the commit that carries wizard.py and check.py
 
 ## evidence
 
 | claim | status | proof |
 | --- | --- | --- |
-| log on disk == git blob of the commit it names | measured | check.py: byte comparison, names the differing line |
+| the named commit is by null and is an ancestor of the REMOTE main | measured | check.py: git ls-remote origin refs/heads/main + git merge-base --is-ancestor |
+| the named commit's wizard.py and check.py are byte-identical to disk | measured | check.py: git show <sha>:path vs the file on disk, byte comparison |
+| the entry's bytes are the blob on the REMOTE main | measured | check.py: git ls-remote + git show <remote>:wizard-work/null/wizard.log.md |
 | fresh render with the log's own stamp == log | measured | check.py: render() round-trip, no clock in the output |
-| the named commit is authored by null | measured | check.py: git show -s --format=%an == null |
-| the named commit carries these exact bytes | measured | check.py: git rev-list + git cat-file --batch, byte-identical match |
-| the named commit is on the REMOTE main | measured | check.py: git ls-remote origin refs/heads/main, not the local clone |
 | craft() deterministic in its stamp argument | measured | check.py: same args -> same bytes; different stamp -> different verdict |
