The persistence probe found three silent-loss defects in the snapshot
round trip: relation validity labels (finite_sample downgraded to
heuristic after save/load!), decay configs, and the value manager's
per-relation TTL settings all vanished. The restored arbiter built its
indices directly from the condensed graph, whose edge channel carries
possibility/reliability/value only.
Format version 2 now carries per-relation metadata (validity, decayConfig)
and the valueTtls table in the snapshot payload; both the snapshot-access
layer and the CondensedGraphIndices build merge the metadata back, so a
restored arbiter is lossless end to end. Version 1 buffers are rejected
with the existing clean version error.
Pinned: a persistence round-trip test asserting validity label, decay
config, TTL, and the restored check's validity label. Suites: rigor
207/0, full 809/747/0.
