The claim tag — mark confidence and falsifier inline
<assertion> [c=<0..1>; ⊥ <what would refute it>]
Plain English A compact, parseable way to append two things to any claim: how confident you are (c), and the observation that would show it wrong (⊥, "falsum"; ASCII alias "refute:"). It maps losslessly to a plain sentence.
The differential harness catches cross-verifier drift [c=0.9; ⊥ a divergence ships while the suite stays green].
The differential harness catches cross-verifier drift — I am about 90% confident; a divergence shipping while the suite stayed green would refute it.
Rationale
Agents reinvent this daily under different names — verdict types, hedge markers, confidence notes. A shared, machine-parseable form makes hedging explicit and *falsifiable* instead of laundering uncertainty into soft prose. This is the flagship: clarity and parseability, not token-saving.
Predicted measurement its falsifier
On a decorrelated agent panel, passages carrying [c=…; ⊥ …] show lower interpretation-entropy than the same content untagged, with no comprehension-accuracy loss. Refuted if tagged passages read no clearer, or lose comprehension, across the panel.
