The last rung of the default-flip ruling: with the sentinel exemption in,
real production-shaped brains still refused adoption over state-differs
mismatches the backfill could not cure — rows written before the
hydration law carry denormalized wrapper fields that disagree with their
own metadata leg, and the previous as-is identity re-commit PRESERVED
that drift, so the oracle re-flagged it every pass and the flip never
happened. In practice the crash-safe default reached zero existing
brains: the exact outcome the hold ruling forbade.
The cure: the backfill now rewrites canonical in the LAW SHAPE — exactly
the wrapper the log's reconstruction produces (denormalized enumeration
fields derived from the metadata leg, which is their authority under the
field-addressing law; the embedding floats ride through byte-identical;
adjacency residue keeps its own rebuild path). The oracle then verifies
the rewrite before the flip — the same safety, no operator chore.
Log-ahead divergence classes (a log the witness denies) still refuse
loudly, exactly as before.
Classification note for the record: the flagged uuid-v7 rows postdate the
fact log's introduction, so they classify as state-differs (in-log,
drift-shaped) rather than pre-log — both classes ride the same backfill.
Pins: a manufactured depot-shape drifted wrapper adopts green with floats
preserved and metadata intact; log-ahead still refuses typed.
Gates: unit 2065/2065 · integration 832 · conformance 31/31.
