reports/blend: record which evidence predates the seed-derivation change
data/README promised that re-running with an unchanged config reproduces exactly.
That is no longer true for three of the eight runs: adding failure domains put
n_regions and region_locality into the topology seed, which changes the graph
drawn for every config, including those leaving both at their defaults.

default, percolation and redundancy predate that change. A spot-checked cell moves
by 0.3%, about 1.5 standard errors -- ordinary variation between independent
realisations, not a change in behaviour, and within the error bars the report
already states. Closed-form quantities are identical either way.

The README now says which runs are current, which are not, and why.
