Contract — WEYL Cosmology

The contract defines the rules before evidence. All thresholds, embedding parameters, and reserved symbols are frozen here.

Identity

Field	Value
Contract ID	`WEYL.INTSTACK.v1`
Version	1.0.0
Parent Contract	`GCD.INTSTACK.v1`
Tier Level	2

Embedding Configuration

Parameter	Value
`interval`	`[0.0, 1.0]`
`face`	`pre_clip`
`oor_policy`	`clip_and_flag`
`epsilon`	`1e-08`

Reserved Symbols (Tier-1)

These symbols are frozen within a run. Any Tier-2 code that redefines them is automatic nonconformance.

GCD Kernel Invariants (inherited):

omega
F
S
C
tau_R
kappa
IC
IC_min

Domain-Specific Symbols:

hJ
hb
z_eff
Sigma
Sigma_0
sigma8
D1
H_z
chi
Omega_m
C_ell
T_Weyl
J
chi2_red
