+### Origin Probes (11-13)
+
+| Script | Tests |
+|--------|-------|
+| exp_11_gamma_origin.py | Gamma as enumeration cost: gamma/ln(2) = 0.833 bits/level, gamma = temporal partition cost independent of cascade geometry. |
+| exp_12_2d_bridge.py | 2D MVAE bridge: generalized formula fails at 3% error in 2D; MED suggests 2D needs only 2 patterns. |
+| exp_13_4d_divergence.py | 4D DNS validation: predicted k=20 vs DNS k=10.78; offset grows with dimension, not constant k-1. |
+
+### Euler Gap Analysis (14-16)
+
+| Script | Tests |
+|--------|-------|
+| exp_14_euler_gap_derivation.py | Euler gap closed form via 240=F3*F4*F5*F6 and Bernoulli B4. gamma enters irreducibly — not derivable from Fibonacci or cascade geometry. |
+| exp_15_delta_closed_form.py | Delta = ln2 - (3-phi)/2; l_MVAE shares CF prefix [1;1,1,1] with phi but is structurally distinct. |
+| exp_16_r_plus_geometry.py | R+ bridge geometry: Landauer-Schwarzschild manifold with curvature kappa = 2*ln^2(2) at the MVAE fixed point. |
+
+### Temporal & Cosmological (17-18)
+
+| Script | Tests |
+|--------|-------|
+| exp_17_temporal_euler_gap.py | 4th dimension is temporal (confluence period-4, not spatial cascade). 240 = cross-dimensional mode product F3*F4*F5*F6. Z_temporal/Z_spatial = ln(2) exactly — temporal ordering costs 1 Landauer bit. Gamma is period-independent enumeration cost. **PARTIALLY SUPPORTED** |
+| exp_18_entropic_pressure.py | Euler gap as entropic pressure signature. dtau/dt decomposes into spatial (SEC pump) + pressure (gap) terms. Pressure fraction grows 0%→0.65% from z=0→z=1000. Total effective time 403,384 Gyr; pressure contributes 2,435 Gyr. gap/sec_pump matches 1/(240*pi*sec_pump) at 0.48%. **PARTIALLY SUPPORTED** |
+
+### Gamma & Separation (19-20)
+
+| Script | Tests |
+|--------|-------|
+| exp_19_gamma_harmonic_pac.py | Tests gamma as harmonic residual in PAC trees. PAC sums are regular (no pole, no gamma). Li_2(1/phi) = pi^2/10 - ln^2(phi). sum(phi^{-k}*H_k) = phi*ln(phi). gamma = -psi(1) = cost of discrete enumeration. Xi = (arithmetic regularization) + (geometric PAC content). **PARTIALLY SUPPORTED** |
+| exp_20_separation_counting_branching.py | Physical separation of Xi = gamma + ln(phi). Branching-only: cost/level = ln(phi) exactly, gamma absent. Counting-only: residual = gamma exactly, ln(phi) absent. Interpolation shows Xi requires alpha > 1 (SUM, not average). Physical systems confirm: QHO shows gamma, trees show ln(phi). **CONFIRMED** |
+
+### Harmonic Bridge (23)
+
+| Script | Tests |
+|--------|-------|
+| exp_23_harmonic_bridge_spectral.py | Tests whether gamma-phi-pi^2 triangle arises from single spectral operator. PAC Laplacian: trace -> 1+phi, spectral radius ~ phi. Mixed spectral measure M(s) = sum(phi^{-k}/k^s): M(0)=phi, M(1)=2*ln(phi), M(2)=Li_2(1/phi). Li_2(1/phi) = zeta(2)*F_4/F_5 - ln^2(phi) confirmed exactly. PAC weights -> ln(phi), uniform weights -> gamma. Xi is irreducibly a SUM of two independent spectral invariants. **PARTIALLY CONFIRMED** |
+
+### Xi Spread (26)
+
+| Script | Tests |
+|--------|-------|
+| exp_26_xi_spread_resolution.py | Resolves the 0.12% spread between Xi = gamma+ln(phi) and Xi = 1+pi/55. Spread = gamma - (1+pi/55-ln(phi)): the Fibonacci spectral formula approximates gamma as 0.5759 (99.77% of actual 0.5772). Physical systems (CA 1.05787, Mobius 1.0581) fall BETWEEN the two, consistent with both being partial descriptions. Spectral Xi(N) crosses Xi_Fib at N=26.25, matching N*=3F_10/(2pi)=26.26. **RESOLVED** |
+
+### Physical Separation (25)
+
+| Script | Tests |
+|--------|-------|
+| exp_25_separation_physical_systems.py | Tests gamma/ln(phi) separation across 5 physical systems where Xi appears. Pure counting (Mertens product) → gamma at 0.03% error, no ln(phi). Pure branching (SEC stress field) → 1/phi equilibrium, no gamma. Mixed systems (CAs, She-Leveque, Landauer) show both. She-Leveque cascade: 83.5% branching (d*F_{d+1}), 16.5% counting (temporal correction). **CONFIRMED** |
+
+### Cascade Refinement (24)
+
+| Script | Tests |
+|--------|-------|
+| exp_24_cascade_spectral_correction.py | Sharpens exp_21's 2.8% error using pi^2 spectral correction from harmonic bridge. 8 models tested; winner: k(d+1) = d*F_{d+1} + d*(ln(2) - 1/pi^2). For 3+1: k = 10.776 vs DNS 10.78 (0.04% error, 66x improvement). Temporal correction decomposes into +ln(2) (Landauer ordering) and -1/pi^2 (spectral damping). Spectral correction is always 14.6% of Landauer term. Updated predictions: k(2+1)=5.18, k(4+1)=22.37. **CONFIRMED** |
+
+### Free-Streaming Cosmology (27)
+
+| Script | Tests |
+|--------|-------|
+| exp_27_free_streaming_signature.py | Derives testable predictions from PAC Eddington regulator + free-streaming exemption. Scale-dependent PAC dilation: k > k_fs (interacting) gets enhanced, k < k_fs (free-streaming) standard. P(k) boost ~5.8% at small scales. BAO shift: r_s ~ 142.9 Mpc (vs 147.1, 2.8% shift). H_0 shift +2.0 km/s/Mpc toward SH0ES. S8 tension direction correctly predicted. 5 falsifiable predictions for Euclid/Roman/Simons Observatory. **TESTABLE** |
+
+### Cascade & Cosmological (21-22)
+
+| Script | Tests |
+|--------|-------|
+| exp_21_4d_temporal_cascade.py | 3+1 spacetime temporal correction to She-Leveque cascade. Best model: k(d+1) = d*F_{d+1} + d*ln(2), giving k(3+1) = 11.08 vs DNS 10.78 (2.8% error). Structure function exponents computed. Predictions: k(2+1) = 5.39, k(4+1) = 22.77. **PARTIALLY SUPPORTED** |
+| exp_22_pac_eddington_regulator.py | MVAE rate limit as natural regulator for entropic time dilation. Hard cap: dtau/dt <= (1+z)*Xi. Soft regulation via tanh. JWST mass predictions: regulated model prevents overflow. CMB tension resolved via free-streaming exemption — PAC dilation is LOCAL (interacting systems only). **SUPPORTED WITH CAVEAT** |

 ### Open Questions
 
-- **gamma**: Xi = gamma + ln(phi) but gamma is NOT derivable from Fibonacci, cascade geometry, or MED. It enters through harmonic series / number theory — the origin is unknown.
+- **gamma**: Xi = gamma + ln(phi) but gamma is NOT derivable from Fibonacci, cascade geometry, or MED. It enters through harmonic series / number theory — the origin is unknown. Exp_11 shows gamma/ln(2) = 0.833 bits/level (enumeration cost), exp_17 shows it's period-independent.
 - **2D bridge**: The generalized bridge formula doesn't extend to 2D (3% error). MED suggests 2D needs only 2 patterns (not 3), which may require a dimension-dependent bridge.
 - **4D cascade**: DNS measured k=10.78 vs predicted k=20. The offset grows with dimension — not a constant k-1.
+- **Temporal vs spatial**: Exp_17 establishes 4th dimension as temporal (confluence period-4), with Z_temporal/Z_spatial = ln(2). Is there a unified formula for the spectral contribution across d spatial + 1 temporal?
+- **Entropic pressure regulator**: Exp_18 shows JWST mass predictions need a regulator (log M ~ 380 vs observed ~7). The entropic time dilation formula dtau/dt needs a saturation mechanism at high z.
+- **1/(240*pi) exactness**: The Euler gap approximation sits at 0.09% — structural but not exact. What is the correction factor?
