One input can sustain two stable states.

Where the arguments meet

The Canonical Spectral-Curvature Field: A Unified Operator Origin for Coherence, Dissipation, and Spectral Budgets →
A positive selfadjoint carrier generates coherent evolution and dissipative relaxation through its functional calculus. The modular spectral measure identifies precisely what the ordered ratio readout retains.

Cross-Domain Spectral Ratio Structure: Refined Recurrence, Robustness and Diagnostic Limits →
Ordered spectral-ratio profiles recur across several hydrogen and image readouts, with more moderate Kerr comparisons. The full controls distinguish reproducible structure from exclusive privilege of the original library.

From Source Structure to Spectral Profiles: Generation Mechanisms and Observable Readouts in the Canonical Spectral-Curvature Framework →
Hydrogen radial shells, Gaussian exchange and Kerr resonance boundary conditions generate spectral profiles by distinct mechanisms. Exact counterexamples and calibrated responses show what pooled ratios lose and what observations recover.

Adaptive Spectral Carriers: Time Ordering, Reciprocal Memory, and Linked Coherent–Dissipative Response →
Reciprocal memory changes the carrier along the trajectory. Instantaneous alignment survives along realized histories, while time ordering and full feedback change the response.

Sustained Adaptive Spectral States: Global Attraction, Nonlinear Gain, and Linked Coherent–Dissipative Response →
A declared rate port sustains nonzero states, with global attraction under a strict curvature condition. Nonlinear gain and freely responding memory distinguish the adaptive system from a matched fixed carrier.

Slow Passage and Prepared Hysteresis in Adaptive Spectral Carriers →
A slow sweep delays switching past the static fold by a preparation-dependent amount. The prepared cycle has a nonzero geometric loop limit, while physical maintenance work grows as the sweep slows.

Transport and Projective Reduction in a Source–Readout Derivation of Einstein Gravity →
Reconstruct the affine connection from smooth transport, remove the projective ambiguity with a volume-restored observable, and follow the complete off-shell spin-two bootstrap to Einstein–matter dynamics within the admitted realization.
