  data-driven mined-pattern substitution table + tuned xz: underperformed
  dict-auto-xz

Mined-pattern substitution table (frequent tags/words/fragments) + tuned xz. archive=24,616,268; decompressor.zip=943; total=24,617,211. Underperformed AutoZip's prior dict-auto-xz best (24,564,096) by ~53 KB. Likely overfitting/noisy substitutions versus a hand-curated candidate list. Roundtrip verified.
