Written with Claude. The sentinel that existed to remember what the system forgot The clearest example of a ghost-guard (a check that protects against a condition that no longer exists, or never should have) I’ve found is one the field-assessment platform created for itself. On every re-cost pass, the cost agent (the automated step that recalculates repair costs) re-emits an engineer’s years override under its own author tag. That one round-trip erases the human-authored signal from the append-only event log (a tamper-evident journal of every change, keyed by author and timestamp). The system then stamps a sentinel flag called _years_auto (a presence marker the gateway reads to infer ownership), so it can later infer whether an engineer or the agent wrote the value, because the round-trip already destroyed that information. ...

Written with Claude. The field visit, the data analysis, the issue filing, and this blog post were all done in one session. The Core Problem The worst thing an AI pipeline can do is put a plausible falsehood in a delivered report that nobody catches. Not a typo. Not a formatting issue. A statement that reads like a field observation, passes review because it sounds right, and lands in front of a client as fact. ...
