Duplicated-fact drift is the fourth error class and the only one with no executable rule. No positive control catches it (both copies are internally consistent) and re-derivation does not either (the copy reproduces whatever it was copied from). It is caught only by reading a copy against its source, which nothing in the loop required. facts.toml holds 15 facts and is GENERATED by `make facts-gen` from cb-cost, dep-weight and rule-coverage. The trap this task named — a hand-maintained registry that becomes another drifting copy — is closed by facts-check re-running the instruments and failing when the committed registry disagrees with them. A stale registry cannot certify stale artifacts. An artifact quoting a fact tags it: **$93.15** <!-- fact --> with the key. 17 occurrences across 5 artifacts are now checked. Falsified before being believed: changing CostAccounting.md line 158 from $93.15 to $92.87 — the exact historical drift — produced exit 1 naming the file, the line and the expected value. Tested against the class it exists to catch, on a real artifact, not only in its self-test. It then caught a live tag inside its own documentation example in InnerLoop.md within the hour. Third time a gate has failed on its own pass's work. What it does not close is stated rather than implied: 22 untagged literal copies remain and are reported, not failed. Tagging is opt-in, a number can legitimately recur, and a gate that fires on coincidence gets routed around. Naming the uncovered surface beats claiming the class is closed. InnerLoop single-source-of-fact moves from prose to executable — v1.3. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
