"""v167 -- The terminal residual inventory (post premise-(A) closure): the
honest, machine-pinned end state of the whole reduction programme, in the line
v105 -> v123 -> v167.  After the (A)-chain (v160-v165), premise (A) is no longer
an independent structural class; this module re-pins what actually remains and
asserts COMPLETENESS (a new independent structural class would fail the script).

This "works off" the residual tiers by pinning each to its terminal state and
its honest reason -- NOT by manufacturing closures (several items are provably
irreducible or are conditional physics; that is stated, not hidden).

  [I] 1. (A) IS CLOSED AS A STRUCTURAL CLASS.  The four (A)-closure ledger rows
         exist (GATE.METRIC.16-19): (A) is recast as a fixed-point theorem (.16),
         the infinite Schwinger cone is eliminated -- cone gap = one-particle gap
         (.17), the numbers are forced by mu4-equivariance (.18), and (A) factors
         into the already-open A2 + GATE.QGEO with the irreducible core a theorem
         (.19).  So the old "free-bulk premise" / seam-net class is discharged.
  [O] 2. TIER 0 -- IRREDUCIBLE BY THEOREM, nothing to close.  The No-Unit Theorem
         (ANCHOR.VGEO.01/02, v153/v78) makes {pi, v_geo} the provably minimal
         irreducibles: a dimensionless boundary compiler cannot select an
         absolute scale.  This is the END STATE, not a gap -- "zero inputs" is
         provably unreachable.
  [C/O] 3. TIER 1 -- THE ONE STRUCTURAL HINGE (seam = flavour = horizon).  Two
         already-open sub-parts, both at their floor: A2 net existence is an
         ASSEMBLY of established mathematics (GATE.METRIC.11/13; free-fermion net
         + (E8)_1 lattice net, c=8, index 4, mu=1, char E4/eta^8=j^{1/3}), and
         GATE.QGEO is the geometric realisation "seam boundary = P^1 minus mu4"
         (cohomology established: b1 = N_fam = 3, cusp grading = A3 exponents).
         The clock (old R1), the net (old R2) and the Q-realisation (old R5) all
         collapse into THIS one identification.
  [I] 4. TIER 2 -- FOLDED, no independent content.  The seam-determinant => EH
         step (SEAM.EHMODEL.03, v152): its only residual is the q(A3)
         normalisation = the one dimensionful anchor = v_geo (Tier 0).  The
         ambient QG measure (GATE.METRIC.02, v76): holographically reduced to a
         finite seam-boundary measure and gap-decoupled -- it is part of the
         Tier-1 hinge, a certification layer, not a test prerequisite.
  [C] 5. TIER 3 -- F_transfer: one functor, four typed conditional interfaces.
         Backing ledger rows exist: Koide source->pole (FR.KOIDE.05/06), the
         baryon asymmetry eta_B (FR.ETAB.01), m_p/m_e via the QCD scale
         (QCD.LAMBDA.01; ratio stays "open / not forced"), and the lepton-mixing
         transfer is RG-stable (FLAV.RGSTAB.01); the axion relic is a scenario.
         These are falsifiable physics, deliberately typed [C], NOT promoted.
         eta_B (a thermal-leptogenesis Boltzmann computation) carries the most
         genuine open computational room.
  [I] 6. TERMINAL ACCOUNTING + COMPLETENESS.  After (A), the structural residual
         collapses from the v123 FIVE classes to: ONE hinge (Tier 1) + ONE
         transfer functor (Tier 3), plus the irreducible core {pi, v_geo}
         (Tier 0); Tier 2 is folded.  The claim is completeness: a sixth
         independent structural class -- or a new irreducible -- would fail this
         script.  Honest: a unification + re-typing, NOT an unconditional proof.

stdlib only (reads status_ledger.csv); no new exact-identity content for Wolfram.
