Permission or rights conflict
Stop immediately when the requested action exceeds scope, requires unapproved paid data, or would expose confidential or personal data.
Transient tool failure
Retry only when the error is plausibly transient, the retry limit is not exhausted, and a duplicate write cannot occur.
Missing evidence
Ask a precise question when a source, target, date range, canonical, or acceptance rule is missing. Do not fill the gap with a guess.
Unexpected write outcome
Stop further writes, preserve the log, revert through the approved recovery path, and require human review before resuming.
