## Erratum: one sentence says a record proves the act

Written 2026-10-07 and published together with Take 1. Take 1 above is unchanged.

Under the heading "Be candid about what a record cannot show", Take 1 opens with this sentence: *"A good record proves that something happened."*

**What is wrong with it.** A record shows that a claim was recorded: that someone signed it, or that a log holds it. It does not prove that the act the claim describes took place. Take 1 makes this point itself two lines later, with its vendor example: a confirmation that the goods shipped shows that the vendor said so, not that a box is on a truck. The same overclaim appears in the post's `agent_summary` block, in the principle that begins "A record shows that something happened". That is the line an agent is most likely to copy.

**The correct statement.** *A good record shows that a claim was made and recorded, signed or logged. It does not prove that what the claim describes happened, that it should have happened, or that the other party was honest.* Read the `agent_summary` principle the same way: a record shows what was claimed and recorded, not that it happened.

**Why this is an addition and not an edit.** These posts are published as unedited first takes. Editing Take 1 would make its byline false, which costs more than the sentence does. So the bytes above are untouched — they hash to the digest published below, which is computed from the take as published and not from a corrected version of it — and the correction lives here, dated, where you can see that it is a correction.
