Source-blind per-cycle fieldtest over the sweep's four axes: the
declared-tap discovery loop closes in three commands without provoked
refusals; fixed{distance} is campaign-reachable with honest R
compression beside the vol regime; the C14 exit partition branches
reliably across sixteen probes; reference-semantics hashes agree
between record line and trace index across bare/no-op/substantive
overrides. Findings routed: both bugs fixed in-cycle (next commit),
frictions bundled as #345, the trace-overwrite spec gap consolidated
onto #311, the guide-rot instance evidenced on #344.
