Mathematical scope

• Defines bilateral deficiency intrinsically through bipolar residual
  restrictions.
• Proves a size-preserving bijection and solution-polynomial correspondence
  with independent dominating sets of formula graphs.
• Develops algebraic operations, MaxSAT recovery, and the fixed-width
  complexity boundary while separating exact clause width from exact signed
  occurrence.
• Establishes bilateral deficiency as the exact gap coordinate
  (i(G)-\mu^*(G)) for regular graphs equipped with a dominating induced
  matching.
• Proves the constructive regular-DIM upper bound, including the cubic
  (7/6) ratio bound.
• Gives a connected edge-cover amplifier and connected cubic-DIM families with
  linear gap; the (1/72) density is sharp within that construction.
• Proves that order 50 is minimum among finite simple cubic graphs admitting a
  dominating induced matching and satisfying (i(G)>\mu^*(G)).

Assurance additions

• Three named finite threshold encodings have native- and Lean-checked direct
  LRAT paths; four native derivations are retained across the three formulas.
• The eight-variable terminal signature is proved exactly in Lean from a
  visible hard-coded transcription of the ten attributed clauses.
• A standard-library clean-room validator independently reconstructs the
  threshold encoding and checks a seven-formula exhaustive semantic corpus.
  This is producer-side validation, not independent reproduction.
• Imported results now have a typed dependency ledger.
• The artifact is separated into compact core, optional 5.79 GB extended proof,
  and documentation layers.

Press or Zenodo payload. Later review, reproduction, formalisation, correction,
or extension should be separately versioned and linked.
