USC Spectral Core: Shannon-Eddington-Bekenstein Information Density Framework
Treats the entire EM spectrum as a unified encoding problem.
Every signal is a field perturbation. Optimal compression = the spectral
basis that minimizes energy cost per bit while staying above the Landauer
floor (kT ln 2 joules/bit).
Theoretical basis:
- Yu, Z. et al. (2025). "The Drivers of the Decline in Supermassive Black Hole
Growth at z < 2." ApJ 995, 205. DOI:10.3847/1538-4357/ae173d
Provides the Eddington-ratio framework extended here as a channel-utilisation
analog: lambda_Edd = actual_flux / max_flux maps to encoded_bits / capacity.
- Shannon (1948), Landauer (1961), Bekenstein (1973), Hawking (1975).
Four-layer constraint hierarchy for N soliton dimensions:
- Shannon : ceiling — channel capacity C = B log2(1 + S/N)
- Geometric : natural — N = (l_max+1)^2 from spherical harmonic truncation
- Bekenstein : snag cap — horizon modes ~ H^{(n-2)/(n-1)} in n-space
- Landauer : floor — each dimension must carry >= 1 bit (kT ln2 J)
Black hole as thermodynamic snag in N-space:
A concentrated entropy region in N-dimensional soliton space behaves as a
DeepCompression. Its horizon is an (N-2)-sphere. Information collapses onto the
horizon surface; the residual that doesn't fit leaks back as the Hawking
analog (reconstruction residual). This gives the tightest upper bound on N
and explains why optimal_dimensions() previously over-estimated N — it used
the Shannon ceiling instead of the geometric/Bekenstein natural value.

Gravitational blueshift factor for a signal band near the entropy snag.
Analogy
-------
In GR an infalling photon is blueshifted by: nu_local/nu_inf = 1/sqrt(1 - r_s/r)
Here the "radius" of a band is its fractional entropy:
f = local_entropy / snag_entropy in [0, 1]
r_s/r → f
So: blueshift = 1 / sqrt(1 - f) = 1 / sqrt(1 - h_local/h_snag)
Interpretation
--------------
f → 0 (low entropy, far from snag) : blueshift → 1.0 — no compression
f → 1 (high entropy, at horizon) : blueshift → inf — infinite compression

Distribute N soliton dimensions across signal bands using gravitational

Derivation
----------
The dimension weight per band is the redshift factor (inverse blueshift):

w → 0 → few dimensions (information already captured by the snag)
Low-entropy bands (far from snag, redshifted):
w → 1 → full dimension allocation (need basis vectors to span this space)

a band far from the snag subtends a larger angle and needs more modes.

"""
Mode count after Kerr-analog angular momentum splitting.
In the Kerr metric, frame dragging lifts (l, m) degeneracy — but the
total number of independent horizon modes is still bounded by the Bekenstein
area law. Kerr rotation does NOT create extra modes; it only redistributes
them more efficiently (better packing near the ISCO / ergosphere).
The compression benefit of high spin is captured entirely by
conversion_efficiency() — η rises from 5.7% (Schwarzschild) to 42.4%
(extreme Kerr). Adding a multiplicative factor to n_base here would
double-count the spin advantage and push encoded_bits above Shannon capacity.
Bounded enhancement (ergosphere solid-angle factor):
n_eff = n_base × (1 + spin_param × (√3 - 1))
≈ n_base × 1.0 .. n_base × 1.73 (Schw → extreme Kerr)

Physical interpretation for compression
----------------------------------------
A highly periodic/coherent signal (high spin) has most of its entropy

most of the encoding budget goes to the residual, not the soliton basis.

Energy retained after viscous dissipation traversing entropy space.
Analogous to Shakura-Sunyaev α-disk viscosity: friction converts

retained = exp(−μ × |1 h_local/h_snag|)

Physical meaning for compression

μ ~ 0.1 : typical accretion disk (Shakura-Sunyaev α ~ 0.010.1)
μ = 1.0 : maximally dissipative — most energy lost before reaching snag
High-friction systems have larger residuals regardless of spin or geometry.
Entropy is a law, not a suggestion — friction cannot be set to zero in
practice; it sets the irreducible floor on reconstruction error.

"""
Treat a concentrated entropy region in N-dimensional soliton space
as a DeepCompression snag.
Geometry
--------
In N-dimensional space the DeepCompression horizon is an (N-2)-sphere.
Its information capacity follows the Bekenstein bound generalised to
N dimensions:
horizon_modes ~ H^{(N-2)/(N-1)}
where H = signal_entropy_bits and the exponent comes from:
- BH radius r_s scales as H^{1/(N-1)} (Bekenstein: S ~ A ~ r^{N-2})
- Horizon area ~ r_s^{N-2} ~ H^{(N-2)/(N-1)}
Hawking residual (reconstruction residual)
------------------------------------------
The analog of Hawking temperature T_H ~ 1/r_s ~ H^{-1/(N-2)}.
Higher entropy (more massive BH) = colder = less residual leakage.
The residual is the portion of the signal that the snag did not absorb
and must be encoded separately.
Behaviour across N
------------------
N=3 : horizon_modes ~ H^{1/2} — square-root compression (most efficient)
N=4 : horizon_modes ~ H^{2/3}
N=10 : horizon_modes ~ H^{8/9}
N->∞ : horizon_modes -> H — no compression (each bit needs a dimension)
Lower-dimensional soliton spaces are therefore *more efficient* under this
model — the snag is most powerful when N is minimised to the signal's true
intrinsic dimensionality.
