abstract: >-
  DSFB-Database is an empirical prior-art demonstration of the
  Drift-Slew Fusion Bootstrap (DSFB) used as a deterministic, read-only
  structural observer over residuals already emitted by SQL database
  engines (PostgreSQL pg_stat_statements / pg_stat_io, SQL Server
  Query Store + DMVs, MySQL Performance Schema, Oracle ASH/AWR).
  Five operator-legible motif classes (plan-regression onset,
  cardinality-mismatch regime, contention ramp, cache/buffer collapse,
  workload phase transition) are emitted as a replayable episode
  stream with bytewise-deterministic SHA256 fingerprints. Evaluated on
  five public datasets: Snowset, SQLShare, CEB, JOB, and TPC-DS via a
  controlled perturbation harness.
