   5# SI Bridge Closure: Unique Calibration Map From RS-Native Units to SI
   6
   7## Status: STRUCTURAL THEOREM (0 sorry, 0 RS-internal axiom; closure 2026-05-09).
   8
   9## What this module closes
  10
  11This module closes the SI **conversion map** (the named open frontier of the
  12dimensional bridge): once the dimensional anchor is supplied, the tick,
  13voxel, and coherence-mass conversion factors are uniquely determined.
  14
  15The framework predicts, in RS-native units, the dimensionless triple
  16  c_RS = 1,  ℏ_RS = φ⁻⁵,  G_RS = φ⁵/π
  17together with the recognition/Planck bridge identity
  18`G·π·ℏ = λ_rec²·c³` in the native gauge (`λ_rec = ℓ₀ = 1`).
  19
  20We formalise the SI bridge as three positive conversion factors
  21  a_T  = sec/tick    (one tick in seconds)
  22  a_L  = m/voxel     (one voxel in metres)
  23  a_M  = kg/cohmass  (one coherence-mass in kilograms)
  24together with three constraints obtained by matching dimensionless
  25RS predictions against the SI values of c, ℏ, G:
  26
  27  c-constraint:  c_SI = c_RS · a_L / a_T
  28  ℏ-constraint:  ℏ_SI = ℏ_RS · a_M · a_L² / a_T
  29  G-constraint:  G_SI = G_RS · a_L³ / (a_M · a_T²)
  30
  31Under SI-2019 conventions, `c_SI` and `ℏ_SI` are exact definitions. `G_SI` is
  32the CODATA measurement that anchors this particular bridge.  The module proves
  33uniqueness of the calibration; it does not predict the SI value of `G`.
  34
  35## Main result (this module)
  36
  37**`a_T_sq_eq`**: under the c, ℏ, G constraints with RS predictions plugged in,
  38
  39  a_T² = π · ℏ_SI · G_SI / c_SI⁵
  40
  41i.e. **τ₀ = √π · τ_Planck**. Uniquely determined; no further input.
  42
  43**`tau0_eq_sqrt_pi_planck_time`**: closed-form τ₀ in seconds.
  44
  45The full triple `(a_T, a_L, a_M)` is uniquely determined in closed form,
  46conditional on the supplied SI anchor.
  47
  48## Honest accounting
  49
  50The framework's claim is now precise:
  51* **Zero free dimensionless parameters**: all RS dimensionless ratios
  52  (φ-power expressions) are forced by T0–T8.
  53* **One dimensional anchor for SI display**: any pure-number theory needs a
  54  dimensional anchor to convert native units into SI. Modern SI (post-2019)
  55  makes this anchor concrete: with `c_SI` and `ℏ_SI` exact by definition, one
  56  additional dimensional measurement (here, `G_SI`) fixes the conversion map.
  57* **Reduction over the Standard Model**: the SM has 19+ free dimensional
  58  parameters (masses, mixing angles in GeV). RS reduces to 1.
  59
  60## Sub-frontier remaining (cosmic-Z hierarchy)
  61
  62Under the Planck-anchored bridge τ₀ = √π · τ_Planck, the rung-3 identification
  63of the electron (m_e^RS = φ³ in coherence-mass units) gives a substrate-frame
  64mass at the Planck scale, NOT at the observed 0.511 MeV. The hierarchy factor
  65between substrate and electroweak scales is the cosmic-Z dressing scale,
  66formalised separately in the Z-aging framework. This is a structural fact,
  67not a free parameter: the same hierarchy factor is shared by all SM masses.
  68
  69The framework's claim is NOT that the electron sits at φ³ × m_Planck.
  70The claim IS that the dimensionless electron-mass ratio in coherence-mass
  71units is φ³, with the substrate-frame coherence mass related to the Planck
  72mass by a Z-aging factor downstream.
