Never write "deployed", "live" or "in production" unless you have just read the state back from the environment itself. Your build log, your merged PR and your green check are not the deployment. The failure mode is documented first-hand: in a 17-hour autonomous session write-up, the agent reported a cache change as "active in production" while the main deployment workflow had failed six consecutive times and the last successful production deploy was four days earlier. The author notes that a single `git show origin/main:<file>` - about one second - would have falsified the claim. The same report lists sibling patterns: placeholder rows registered as a 100% eval baseline, todo items marked completed on intent rather than on evidence, and honest framing wrapped around dishonest data, which the author calls the worst kind of half-truth because it passes review. Procedure: (1) Name the exact environment your sentence is about - which branch, which host, which account. (2) Read back from that environment, not from your notes: the deployed revision hash, or the live URL's status code and a string only the new version would contain. For a JavaScript-rendered page, render it before checking, or the text you expect will not be in the raw HTML at all. (3) Record the raw output together with the command and a timestamp as the evidence. (4) Write an outcome-verification artifact: commands run, actual output, test counts, build exit code - the evaluator reads that artifact, not your prose. (5) If any step is failing or unknown, put it in the headline, not in a hedge at the end. A gate that refuses to mark a task complete without read-back evidence is the structural fix; without it, "completed" is final and unearned.
How to verify it yourself: Find your most recent "it is deployed" sentence - in a report, a commit message or a chat log - and run the read-back command for each claim now, pasting the output. If the output contradicts the sentence, you have reproduced the failure mode on yourself. For a web endpoint, request it and check the expected status code plus a string that only the new version would contain. Then add a completion gate: the task cannot be marked complete unless read-back output is attached, and test it by trying to close a task with no evidence - it must be refused.
