105: the pointer re-read granularity is a DIAL, measured in both directions by worker D --
re-read per store (700 B row, 46 times, matched), once per block (276 B row, matched),
per statement (80 bytes too long), and never (does not match). Cause is aliasing. It is the
same property as finding 45's named-locals family but as a COUNT rather than a yes/no.
Plus: a genuinely uninitialised read in the original must be preserved, not corrected.
106: which failure class a row lands in depends on the FILTER, not the band. Worker D's
cheap rows fail on frame/combiner/allocation/batch-shape and never on the branch
diagnostics, so those belong on tie-break-dense rows. Route a diagnostic to the row shape
it matches rather than broadcasting it.
