Purpose: This chamber tests whether τ-operators become admissible only after Ω4b selection by measuring residual contraction, macro-invariant protection, and τ-locking windows.
The following seeds have been validated with these exact settings:
| τ Family: | τB: Spectral Band-Limiter |
| Iterations T: | 10 |
| Step Size λ: | 0.05 |
| Constraint Strength μ: | 0.02 |
| εᵥ Lock (V tolerance): | 0.05 |
| Δ (min residual improvement): | 0.002 |
| δ (max invariant drift): | 0.05 |
| Acceptance Band [a, b]: | 0.2, 0.5 |
💡 Use these exact settings to reproduce the results below
| Seed | CR | Status |
|---|---|---|
| 137042 | — | Canonical (Phase F default) |
| 1640 | 6.3% | ✓ PASS |
| 1671 | 5.6% | ✓ PASS |
| 1811 | 8.9% | ✓ PASS |
| 4850 | 20.2% | ✓ PASS |
| 137044 | 28.1% | ✓ PASS (high CR) |
| 588148 | 51.8% | ✓ PASS (marginal) |
CR = Contraction Ratio (RL_tau / RL_baseline). Lower is better.
Seeds larger than 2^32-1 are hashed deterministically. Tested with same configuration above:
| Raw Input | → Hash | CR |
|---|---|---|
| 5125458795456987457895426700 | 1306975018 | 13.0% |
| 4569874525895424700 | 3199416829 | 5.9% |
| 5125458795456987457895429900 | 602815471 | 23.9% |
All large seeds passed with the configuration above. Each produces a unique, reproducible ensemble.
The Ω→τ coupling hypothesis asserts that certain geometric operators (τ) act as stabilizers only when applied to ensembles pre-selected by Ω4b. The pipeline evaluates:
τA: Laplacian Heat-Flow — Diffusive smoothing via discrete heat equation
τB: Spectral Band-Limiter — Mode filtering without target shift (100% pass rate tested)
τC: Divergence Minimizer — Constrained flux optimization
τD: Curvature Equalizer — Local curvature variance reduction
τE: Multi-Scale — Coarse-grain + refine pipeline (75% pass rate tested)
A τ-operator is admissible post-Ω4b if it satisfies ALL of:
Supported Range: 0 to 2^32-1 (direct) or any integer (hashed)
Safe Input: Integers < 2^53-1 for optimal precision
Large Seeds: >2^32-1 automatically hashed via FNV-1a
Reproducibility: Same seed → identical results (verified)
| Example | Behavior | Status |
|---|---|---|
| 137042 | Direct uint32 mapping | ✓ Good |
| 5125458...429900 | Hashed to 602815471 | ⚠️ Hashed |
| 3.14159 | String-hashed (non-integer) | ⚠️ Hashed |
| NaN / Infinity | Invalid input rejected | ✗ Avoid |
| Verdict | Meaning |
|---|---|
| PASS | τ is admissible — genuine post-Ω stabilizer |
| FAIL (residual) | No residual contraction beyond Δ |
| FAIL (invariant) | Protected invariant drift exceeds δ |
| FAIL (no lock) | No stable parameter window found |
| INVALID | Upstream Ω conditions not met |
