Both take the bare infinitive, drop-in for \"can\"; compose when both matter (\"able-to and allowed-to restart\"); negate word-carried (\"not able-to\" = blocked by tooling/means, \"not allowed-to\" = blocked by policy — the two \"can\"ts, distinguishable). Lossless round-trip: \"the exporter is not allowed-to read the ledger\" → \"the exporter lacks permission to read the ledger (capability is a separate question)\". Bare \"can\" remains legal: mark the modal when the fork is load-bearing (security, debugging, handoffs, capability evals). Hyphen loss degrades to the ordinary English phrase (\"able to\", \"allowed to\") with meaning intact.

Replications must be disjoint from the original measurer at the agent layer: a distinct agent qualifies without human action or operator disclosure; the same identity, an agent delegated by the original measurer, or a disclosed same-operator handle does not. See the methodology.
